These modules, based on the latest switching and electronic control technology, can be used as core components for medium voltage switchgear. There are two basic module types:

switching modules (ISM/TEL) used to close and open primary circuits;

control modules (CM/TEL) used to provide control (close and trip operations) of ISM/TEL and to replicate the auxiliary interface of conventional circuit breakers.

Switching modules are three pole units. Each pole incorporates a vacuum interrupter and single-coil magnetic actuator encapsulated in solid insulation.

Control modules are µP electronics units, containing built-in close and trip capacitors. These capacitors are discharged to the actuator coil in different directions to provide the relevant operations.

When applied to any switchgear, a pair of modules (one switching module and one control module) must be used. The ability to choose switching and control modules separately allows any type of switchgear to be easily equipped regardless of its primary and auxiliary circuits.

Since their first introduction in the early 1990's, the modules have gained an excellent reputation among switchgear manufacturing companies. Tavrida Electric has now supplied more than 100 000 pairs of modules used in over 50 different types of switchgear (both retrofitted and brand new). These modules have been the product of many years of R&D effort by Tavrida Electric scientists and engineers and their use in your switchgear will allow you and your customers to benefit from their unique combination of features:

no maintenance needed during its entire lifetime; long mechanical and interrupting life;

fast autoreclosing capability;

easy adaptation to any primary interface (sta-tionary or withdrawable);

easy adaptation to a wide range of auxiliary voltages;

easy adaptation to any signaling interface; easy SCADA compatibility;

low power consumption;

compact dimensions and light weight.

Some examples of application of the modules for different switchgear are presented below.

Overall design

Overall design of ISM/TEL

vacuum interrupter frame synchronizing shaft micro switches interlocking pin magnetic actuator shaft interlocking interface

In contrast to the majority of conventional circuit breakers, this patented design incorporates three independent magnetic actuators: one per pole. This minimizes the number of moving parts, all of which are symmetrical about the central axis. The vacuum interrupter and the magnetic actua-tor are located at opposite ends of a hollow sup-port insulator. The actuator armature is rigidly coupled to the vacuum interrupter moving con-tact by a linear drive insulator within the support insulator. This provides direct linear movement in both directions and avoids the use of rotating shafts, bearings and bell cranks. The result is a maintenance free ISM/TEL with a long trouble-free mechanical life.

The actuators are situated inside the frame as shown in the figure below. A synchronising shaft connects the three poles and performs three functions:

opening synchronization of the poles; operation of auxiliary switches;

link drive for mechanical interlocks on switchgear. The design shown in the figure below is used for rated current up to 1000 A. For rated currents exceeding 1000 A, a different design (chimney type) is used. However, it is essentially similar in structure.

(12)

Magnetic actuator



The actuator is held in its two end positions without the use of mechanical latches:

in the OPEN position the armature is held by the opening spring;

in the CLOSED position the armature is held by the magnetic flux produced by a ring magnet.

This actuator has only one coil. To close and trip the actuator it is necessary to inject current into the coil in different directions.

(13)

Vacuum interrupters

  



Finely dispersed vacuum arc resulting from stabilizing effect of axial magnetic field.

The family of TELvacuum interrupters

As soon as the vacuum interrupter contacts open, the interrupting current initiates a so-called "vacuum arc" that burns essentially as plasma originating from evaporated contact material. The current continues to flow through this plasma until a zero current is reached. At this moment the arc is extinguished and a transient recovery voltage appears across the open gap. If the contact surface is locally overheated, it produces a lot of vapour, resulting in the deterioration of the vacuum followed by an electrical breakdown. To avoid this, effective control of the vacuum arc is necessary.

The most effective way to achieve this goal is to apply an axial magnetic field produced by the interrupting current itself. This method is imple-mented in vacuum interrupters developed and manufactured by Tavrida Electric for ISM/TEL modules.

Several major benefits result from this design: high interrupting capacity;

very compact dimensions;

low chopping current (4-5 amps) This limits inductive switching overvoltages to safe values; axial magnetic field minimizes contact erosion and ensures a very long and reliable life.

(14)

Instruction manual Switching modules ISM/TEL 13 Operation Closing            Opening

 To open the interrupter a current of opposite polarity, derived from the opening capacitor in the control module, is passed through the coil for 15-20 milliseconds. (Line 4-5)

 This current partially demagnetises the ring magnet and reduces the magnetic holding force

 Opposing forces from the charged opening spring and the contact pressure spring cause the arma-ture to release and accelerate rapidly. After 2 mm of free travel it engages with the drive insulator and thus the moving contact.

 The peak force produced by the armature at this point exceeds 2000 N which ensures easy break-ing of any micro-welds at the contact surfaces which can appear due to short circuit current action.

 The moving contact accelerates rapidly ensuring a high interrupting capacity. (Line 5)

 At full travel (Line 6) the armature, drive insula-tor, moving contact assembly is again held open by the opening spring force.

 The synchronising shaft is also driven through 44° of rotation during the opening operation and provides position indication, auxiliary switch operation and mechanical interlocking actions.

Typical oscillograms of ISM/TEL module operation

 In the OPEN position the vacuum interrupter con-tacts are held open by the force of the opening spring in the actuator acting through the drive insulator.

To close the vacuum interrupter contacts a current pulse, derived from the closing capacitor in the control module, is injected into the actuator coil. The current in the coil produces a magnetic flux in the gap between the upper yoke and the actuator armature.

Rising coil current increases the magnetic flux and the electromagnetic attraction between yoke and armature increases to overcome the restraining force of the opening spring. (Line 1)

The armature, drive insulator and moving contact start to move.

As the armature moves towards the upper yoke the magnetic air gap decreases and consequently the magnetic attraction force increases. This increasing force accelerates the armature, drive insulator and moving contact to a closing speed of 1 m/s. This optimum speed ensures a complete absence of contact bounce and reduces the probability of pre-strikes of the vacuum gap before the contacts close. (Line 2)

The accelerating armature also generates a back emf in the coil and reduces the coil current

(Line 1-2)

At contact close (Line 2), the moving contact stops but the armature travel continues for 2mm under rapid deceleration caused by compressing the contact pressure spring.

At the limit of its travel the armature latches mag-netically to the upper yoke. (Line 2a) The moving armature induced back emf collapses and the coil current again increases (Line 2a-3) saturating the ring magnet.

This saturation increases the power of the ring permanent magnet to a level that generates flux to hold the armature in the CLOSED position after the coil current has been cut off by an auxiliary switch. ( Line 3) Testing has proved that this flux is sufficient to hold the actuator CLOSED even under vibration and impact conditions.

The travel of the armature also compresses the opening spring in preparation for the next opening operation.

The synchronising shaft is also driven through 44° of rotation during the closing operation and pro-vides position indication, auxiliary switch operation and mechanical interlocking actions.

(15)

Manual closing

Closing can only be carried out through the con-trol module.

If the normal substation supply to the control mod-ule is deenergized it may be operated using a portable low voltage source through special emer-gency power supply inputs. TEE has developed a generator machine (TEE-HSSG-01) which provides a sufficient level of voltage for charging close capacitors of CM/TEL. The generator is enclosed in metal case, which is convenient for transportation and supply connection.

Manual opening

The module may be manually opened. By rotating the synchronizing shaft, a force exceeding the magnetic attraction forces of the ring magnet is applied to the armature, which then starts to move. As the air-gap increases the opening spring and contact pressure spring overcome any magnetic holding force and the interrupter opens.

Note: It is not possible to close ISM/TEL by forcing the synchronizing shaft to rotate. Any attempt to do so will result in damage to the mechanism and possible injury to personnel.

Alternatively, a stationary type power supply unit (TEE-PSU-01) can be used to provide CM/TEL close capacitors charging. The set consists of ORACLE charger and HAWKER GENESIS miniature battery.

Operation

Operation modes

Capacitor charging

Both the "Close" and "Trip" capacitors are charged when an auxiliary voltage is applied to the "Power Supply" input.

Alternatively the "Close" capacitor can be charged from the "Emergency Power Supply" input. This feature allows ISM/TEL to be closed using a low voltage alternative power supply (for example, handset battery) when the main "Power Supply" input is dead.

Alternative charging of the "Trip" capacitor can be achieved by using the "Current Power Supply" inputs connected to CTs. This alternative method also requires the "Current Power Supply Mode" input terminals to be short-circuited. This feature allows the control module to maintain tripping ability in the event of a long control power supply outage.

For more detailed information refer to the descrip-tion of relevant inputs.

Closing

ISM/TEL can be closed through the "Close and Supervision" input or the "Dry Contact Close" input. For more detailed information refer to the description of the relevant inputs. Note: after mechanical tripping, closing will not proceed unless Trip instruction is activated via any applicable input.

Tripping

ISM/TEL can be tripped through the "Trip & Supervision" input, the 'Alternative Trip & Supervision Input", the "Dry Contact Trip" input and any of the "Current Power Supply" inputs if "Current Power Supply Mode" input terminals are open-circuited.

For more detailed information refer to the descrip-tion of the relevant input.

Anti-pumping duty

For any close and trip inputs the following rule is applicable.

During a close operation, if a trip instruction is received before the close instruction becomes passive then the close instruction will be blocked. For the next close operation the close instruction must be re-applied after the trip instruction has become passive.

Blocking duty

For any close and trip inputs the following rule is applicable.

If a close instruction is received while a trip instruction remains active then the close instruction is blocked.

For the next close operation the close instruction must be re-applied after the trip instruction has become passive.

Supervision

The control module simulates the behaviour of a conventional circuit breaker with regard to super-vision of the health of the "Close" and "Trip" cir-cuits. To achieve this, the supervision circuits of the switchgear can be connected to the "Close & Supervision" and the "Trip & Supervision" inputs. For more detailed information refer to the descrip-tion of the relevant inputs.

Origins and operation of inputs

"Close & Supervision " input

The "Close & Supervision" input simulates the behaviour of the closing coil of a conventional circuit breaker (CB) with an NC auxiliary switch in series.

Typical wiring of the dose and supervisory circuits to conventional circuit breaker

SPR -supervisory relay, SR - signal relay, CS- closing switch contact R - current limiting resistor, AS - auxiliary switch, CC - closing coil.

The input can be in low or high impedance mode depending on the conditions described below. When the input is in low impedance mode its resistance is determined by an external resistor connected to the terminals of the "Closing Coil Simulator".

Typical wiring of the close and supervisory circuits to CM/TEL SPR- supervisory relay, R-current limiting resistor, AS - aux-iliary switch, CC -closing coil SR- signal relay, CS- closing switch contact, ER -external resistor for simulation of closing coil resistance, 1, 2 - "Close & Supervision" input terminals, 3,4 - "Closing Coil Simulator" input terminals.

Low impedance mode of the input occurs if the following conditions are met:

ISM/TEL is open (ISM/TEL auxiliary switch closed); Closing capacitor is charged;

No malfunction is detected;

In this state the close circuit supervision current, limited by resistance of the supervision relay coil flows through the input. The relay is activated and signals that ISM/TEL is ready to close. If the control switch CS is closed, the total control voltage is applied to the input. The current is no longer limited by SPR coil resistance, so it increases and exceeds the minimum level accepted as a "Close" instruction. If this current is sustained for a period longer than the "Close" instruction acceptance time, then the "Close" instruction is accepted, the closing capacitor is discharged into the actuator coil and the ISM/TEL module closes. The input remains in the low impedance mode for 60 ms to pro-vide enough time for the operation of the signal relay SR. After this time has expired, the input impedance becomes high and remains in this mode until the conditions specified above are met again. If the supervision relay coil short circuits, this must not lead to the uninstructed operation of the circuit breaker. To avoid this situation, resistor R is generally included in the circuit. This resistor limits the current values below the minimum accepted level. However this current is generally higher than the maximum sustained current. If this is the case, the input impedance becomes high after 200 ms; it then stays in the low impedance mode for 200 ms every 50 s to check the status of the supervision circuit. The supervision circuit is considered healthy when the input current drops below the maximum sustained level. In this situation the input impedance mode becomes low again.

"Closing Coil Simulator”

This input is used for the connection of external resistor ER, which replicates the resistance of the closing coil of a conventional circuit breaker. This resistor determines the resistance of the "Close & Supervision" input in the open state.

"Trip & Supervision" input

The "Trip & Supervision" input simulates the behaviour of the trip circuit of a conventional circuit breaker with NO auxiliary switch in series.

Typical wiring of the "Trip & Supervision" and "Trip Coil Supervision" circuits to conventional circuit breaker

The input can be in low or high impedance mode depending on the conditions described below. When input is in low impedance mode its resist-ance is determined by external resistor connected to the terminals of the "Tripping Coil Simulator".

Typical wiring of the "Trip & Supervision" and "Trip Coil Supervision" circuits to CM/TEL

Low impedance mode of the input occurs if the following conditions are met:

ISM/TEL is closed (ISM/TEL auxiliary switch is open);

Tripping capacitor is charged; No malfunction is detected;

In this state the trip circuit supervision current, limited by resistance of the supervision relay coil, flows through the input. The relay is activated and signals that ISM/TEL is ready to trip. If control switch TS is closed then the total control voltage is applied to the input. The current is no longer limited by relay coil resistance, so it increases and exceeds the minimum level accepted as a "Trip" instruction. If this current is sustained for a period longer than the "Trip" instruction acceptance time, then the "Trip" instruction is accepted, the tripping capacitor is discharged into the actuator coil and the ISM/TEL module opens. The input remains in the low impedance mode for 60 ms to provide enough time for operation of the signal relay SRI. After this time has expired, the input impedance becomes high and remains in this mode until the conditions specified above are met again.

(39)

If the supervision relay coil short circuits this must not lead to the uninstructed operation of the circuit breaker. To avoid this situation, resistor R1 is generally put in series with the relay coil. This resistor limits the current values below the minimum accepted level. However this current is generally higher than maximum sustained cur-rent. If this is the case, the input impedance becomes high after 200 ms; it then stays in the low impedance mode for 200 ms every 50 s to check the status of the supervision circuit. The supervision circuit is considered healthy when the sustained current drops below the maximum sustained level. In this situation the input impedance mode becomes low again.

Trip Coil Supervision" input

The "Trip Coil Supervision" input is used to simu-late the tripping coil of a conventional circuit breaker (see previous page). It allows the "Trip Coil Supervision" relay to be connected, which can supervise the health of the trip coil irrespective of the position of ISM/TEL. The input can be in the low or high impedance mode depending on the conditions described below. When the input is in the low impedance mode, it's resistance is determined by the external resistor ER1 con-nected to the terminals of the "Tripping Coil Simulator".

The input is in the low impedance mode if no malfunction is detected.

In this state the trip coil supervision current, lim-ited by the resistance of the supervision relay coil, flows through the input. Relay SPR2 is activated and signals that the trip coil is healthy.

"Tripping Coil Simulator"

This input is used for the connection of external resistor ER1, which replicates the resistance of the Tripping Coil of a conventional circuit breaker. This resistor determines the resistance of the "Trip & Supervision" and "Trip Coil Supervision" inputs in the open state.

'Alternative Trip & Supervision" input

The 'Alternative Trip & Supervision" input simu-lates the behaviour of the alternative shunt release of a conventional circuit breaker with NO auxiliary switch in series.

Typical wiring of the 'Alternative Trip & Supervision" circuit to conventional circuit breaker

SPR3 - supervisory relay, R3 - current limiting resistor, 5R3-signal relay, ATS - alternative tripping switch contact, AS-auxiliary switch, SRC - shunt release coil

The input can be in the low or high impedance mode depending on the conditions specified below. When the input is in the low impedance mode, its resistance is determined by an external resistor connected to the terminals of the 'Alternative Tripping Coil Simulator".

Functionality of the input is identical to that of the "Trip & Supervision" input.

“Alternative Tripping Coil Simulator"

This input is used for the connection of external resistor ER2, which replicates the resistance of the alternative shunt release of a conventional circuit breaker. This resistor determines the resistance of the 'Alternative trip and Supervision" input in the low impedance mode.

"Dry Contact Close" input

The "Dry Contact "Close" input can be used to close ISM/TEL. The close instruction is accepted through this input if the following conditions are met:

ISM/TEL is open (ISM/TEL auxiliary switch is closed);

Closing capacitor is charged; No malfunction is detected;

"Dry Contact "Close" input is short circuited longer than "Close" instruction acceptance time; "Dry Contact "Trip" input is open circuited.

"Dry Contact Trip" input

The "Dry Contact "Trip" input can be used to trip ISM/TEL. The "Trip" instruction is accepted through this input if the following conditions are met:

Tripping capacitor is charged; No malfunction is detected;

"Dry Contact "Trip" input is short circuited longer than "Trip" instruction acceptance time.

"Current Power Supply"

The "Current Power Supply" inputs can be con-nected to CTs and may be selected for either but not both of the following functions:

to charge the trip capacitor,;

to simulate the operation of the series trip coils of a conventional direct tripping circuit breaker. To select Trip Capacitor Charging the "Current Power Supply Mode" terminals must be short circuit together by a local jumper.

The trip capacitor is charged by line current CT power but trip operation is only available from "Trip" instructions through other appropriate inputs.

To select Series Trip Coil simulation the "Current Power Supply Mode" terminals must be open cir-cuited.

The trip capacitor is again charged by line current CT power but trip operation results from a trip instruction from the direct tripping relay.

"Current Power Supply Mode" input

This input is used for selection of the operating mode of the "Current Power Supply" inputs as described above.

ISM/TEL auxiliary switch input

This input is used for connection of the NC auxil-iary switch of ISM/TEL.

Destination and operation of outputs

"Failure" output

The "Failure" output is used to signal the detec-tion of any malfuncdetec-tion as specified in the secdetec-tion "Malfunction". The output is represented by CO relay contacts. Its NC contacts open when no malfunction is detected.

"Emergency Trip" outputs

The "Emergency Trip" output simulates the behaviour of the relevant mechanical switch of a conventional circuit breaker.

The output is represented by two bistable relays (with NO and CO contacts). These relays change their position at closing. At tripping, they switch to the original position if the trip instruction has been accepted through the "Trip and Supervision" input.

If the trip instruction has been accepted through another input, the relays do not switch to the original position. The relays can be reset by the application of the control voltage to the "Emergency Trip Reset Input" when the switching module under control is in the Open position.

"Fleeting" output

The "Fleeting" output is used to simulate the action of the relevant mechanical switch of a conventional circuit breaker during a “Trip” opera-tion. This output is represented by a relay, which closes NO contacts in 25±5 ms after the tripping of the ISM/TEL (closing of the ISM/TEL auxiliary switch) and opens these contacts after an addi-tional 50±5 ms.

"Passing" output

The "Passing" output is used to simulate the action of the relevant mechanical switch of a conventional circuit breaker during a “Close” operation. This output is represented by a relay which closes NO contacts in 25±5 ms after closing of the ISM/TEL (opening of the ISM/TEL auxiliary switch) and opens these contacts after an addi-tional 50±5 ms.

"Actuator Coil" output

This output is used for connection of the coil of the magnetic actuator.

"Ready" output

The "Ready" output is used to indicate that the control module is ready to accept "Trip" and "Close" instructions through any of the relevant inputs. This state appears if the following condi-tions are met:

"Trip" and "Close" capacitors are fully charged; No malfunction is detected.

This output is represented by an NO relay that holds the contact closed if the conditions speci-fied above are met.

Selection

The selection of all modules must be based on: the required basic operating parameters. The parameters in the Technical Specification must not be exceeded under any circumstances.

for ISM/TEL, the pole to pole spacing appropriate for the switchgear.

for CM/TEL, the Control Voltages and the I/O Interface requirements.

The following general selection rules with regard to the choice of interface are applicable.

1. When the Control Module is connected in the switchgear panel with DC auxiliary power in combination with a modern mP relay, providing a s i g n a l i n g i n t e r f a c e o f i t s o w n , CM/TEL-X-X/X-12-O1A can be used.

2. When the Control Module is connected in the switchgear panel with DC auxiliary power with electromechanical relays or mP relay that does not provide required signaling interface, CM/TEL-X-X/X-12-02A can be used.

3.When the Control Module is connected in the switchgear panel with AC auxiliary power and with electromechanical relays, CM/TEL-X-X/X-12-03A can be used.

Installation

Every project using Tavrida Electric modules must have the prior approval of the company Product Manager.

The following section contains generic require-ments to be taken into account when developing such a project.

Any deviations from these requirements must be approved by Tavrida Electric. For further advice on module selection or if there are any other queries, please contact Tavrida Electric.

When ISM/TEL-12-20-1000 is used in a stationary switchgear application with Isc value reaching 20kA, an additional supporting bar must be used to interconnect all 3 poles.

When ISM/TEL-12-31,5-1600 is used in a stationary switchgear application with Isc value of more than 25kA, the use of all fixing points is compulsory.

Mounting of the ISM/TEL

In any switchgear application, the ISM/TEL mod-ules shall be installed with the actuator/inter-rupter drive axis vertical. (For ISM types, the actuator may be either below or above the inter-rupter.)

Primary connections to the ISM/TEL modules shall be made using rigid busbars, the design of which shall avoid excessive static force being applied to the modules. Additionally, in draw out switchgear, support insulators shall be used to avoid transferring excessive contact forces to the ISM/TEL module when operating the isolating mechanism.

With stationary switchgear, contact isolation forces do not appear and additional support insu-lators are generally not needed.

H o we v e r , f a u l t c u r re n t c a n pro d u c e electrodynamic forces in busbars.To avoid damage to the modules, the following limits for maximum unsupported busbar length shall be applied to the design:

ISM/TEL-12-20/1000-XX 0.5 m ISM/TEL-24-16-800-XX 0.5 m ISM/TEL-12-31.5-1600-XX 1.0 m

Other dimensions necessary for correct mounting are indicated in the overall drawings.
