(ZEp TAVRIDA ELECTRIC Excellence in Engineering VACUUM CIRCUIT BREAKER PRODUCT GUIDE

This Product Guide describes the withdrawable vacuum circuit breakers manufactured by Tavrida Electric. Tavrida Electric circuit breakers are designed for rated voltages up to 17.5 kV. Withdrawable vacuum circuit breakers are designed for indoor installation in air-insulated switchgear panels and are intended to perform switching operations in network rated and faulty modes. The breakers consist of the following main components: • Indoor Switching Module (ISM) - The air-insulated ISM incorporates Tavrida Electric vacuum interrupters incorporated in solid dielectric insulator controlled by...

1.2 Definitions Closing Time The closing time is the time period from the moment the close command is applied to the CM to the time when all ISM poles make contact. Opening Time The opening time is the time period from the moment the trip command is applied to the CM to the time when all ISM poles are separated. Break Time The break time is the time period from the moment the trip command is applied to the CM to the time when the arcs in all phases are extinguished. 1.3 Disclaimers Tavrida Electric will not accept any claims for damages caused by improper transport, storage as well as...

2.1 Product Application Field The circuit breaker is usually installed in radial or loop cable or overhead distribution systems. The main applications are:   Switching different types of load in normal and fault modes. Isolating faults in the cable or overhead network. Due to their short closing and opening times (see Table 11), Tavrida Electric circuit breakers can bring significant benefits to the following applications:   Arc flash protection. Automatic backfeed restoration. 2.2 Key Benefits Tavrida Electric circuit breakers provide the following competitive advantages: ...

3.1 Circuit Breaker Coding VCB15_XX_16D(Par1.. ._Par12) Product group ISM type CM and VCB implementation type Table 1 - Product Group Description 1) Please contact your local sales representative for information. 2) 95 kV BIL.

Each VCB has an electrical data label which contains the circuit breaker‘s serial number: Figure 1 VCB electrical data label with serial number The nameplate contains information about the VCB type, the VCB technical parameters and the serial number. The placement of the electrical data label is shown below. 3.2 Circuit Breaker Component Coding3.2.1 ISM Coding ISM15_MD_1 (Par1_(Par2)) Indoor switching module Rated voltage

ISM15 - indoor switching module with rated voltage up to 17.5 kV See Table 2 for the ISM type secriptions. The following ISM implementation types are available: • ISM15_MD_1(Par1_Par2) - Medium duty indoor switching module with rated normal current up to 1250 A. • ISM15_HD_1(Par1) - Heavy duty indoor switching module with rated normal current up to 3150 A. Table 5 - ISM Parameters Description 1) This parameter describes the ISM type(s) that the CM can control. To optimize the operation of each ISM, corresponding settings are used in the CM firmware. Usage of the CM with the incorrect type...

3.2,4 Optional Manual Generator Coding CBunit_ManGen_1 Circuit breaker unit Manual generator Generator type CBunit_ManGen is used to charge the CM_16_1 in cases where the main auxiliary power supply is unavailable. Table 8 - Generator Type Description Figure 11 CBunit_ ManGen_1 (CBunit_ ManGen_2) Figure 12 Designation label

SGkit_Connector_1 (Par1_Par2) Switchgear kit Main circuits connector kit Kit type The SGkit_Connector_1 is used to provide the switchgear fixed contact counterpart for the DOU main circuits connection. Table 9 - Switchgear Kit Parameters Description Figure 14 SGkit_Connector_1(17.5_2000) scope of supply The difference between the kits is the dimensions of the fixed contacts.

3.2.6 Optional Circuit Breaker Interlock Kit Coding CBkit_Interlock_6(Par1) Circuit breaker kit Interlock kit Kit type The CBkit_Interlock_6 is used with the DOU to provide it with optional interlock in case this interlock is required after DOU production. The interlock blocks the DOU rack in/out functionality in case auxiliary voltage (provided for solenoid installed on DOU plate) is unavailable. Table 10 - Circuit Breaker Kit Parameters Description

Optional kit for Control module installation on a DIN rail CBmount_CM_1 Circuit breaker mounting kit Control module Kit type The CBmount_CM_1 is used to mount CM_16_1 on the DIN rail.

Table 11 - VCB Technical Parameters 1) Rating for metal-enclosed switchgear with limited ventilation. Temperature rise type test at 2500 A in Cradle was successfully passed in KEMA. 3) The information in parentheses is in accordance with the national Chinese standard GB1984-2003 at an installation altitude of 1000 m maximum. 5) Smaller timing available upon request. 8) The number of sequential close-trip operations with a 10 second interval should not exceed 10. The number of close-trip operations should not exceed 60 per hour. A sequence of 10s close-trip operations can be repeated only...

Table 11 (Continued) - VCB Technical Parameters 10) At 5 min short-term duty. Continuous current - 5 A. 11) In case of dry contacts “close” and “trip” are open. 12) At Cos j >0.66. 13) At Cos j >0.33.

1) The cable from the electronic relay to the connector block should be shielded and the case should be grounded near the connector. The total length of unshielded wires from the connector block to the CM WAGO connector should not exceed 200 mm. Electromagnetic compatibility requirements are not applicable for the CM USB port, as this port is used only for CM programming during production and not used under service conditions. 2) Test influence is not applicable for the CM “Close” and “Trip” dry contacts.
