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

This User 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 per...

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 Main Technical Parameters Main technical data and circuit breaker technical parameters are presented in the tables below. Table 1 - Main 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. 2) For PCD 275 mm 3) The information in parentheses is in accordance with the national Chinese standard GB1984-2003 at an installation altitude...

For 2000 A For 3150 A At Cos j > 0.66. At Cos j > 0.33. Up to an installation altitude of 1000 m above sea level. Above 1000 m, the external insulation measurement of the VCB must be increased by the atmospheric correction factor Ka in accordance with IEC 62271-1 compared to the insulation measurement at sea level. The maximum allowed altitude is 2000 m above sea level. 1.4 Disclaimers Tavrida Electric will not accept any claims for damages caused by improper transport, storage as well as unpacking. Transport damage must be reported in writing to the supplier as soon as it is discovered....

The vacuum circuit breaker itself does not have labels or seals; however, its main components (ISM, CM and manual generators) have them. VCB, ISM Labels and Seals Each VCB has an electrical data label with a serial number: The electrical data label contains information about the VCB type, its technical parameters and serial number. The placement of the electrical data label is shown below. Figure 2 Electrical data label placement The serial number plate contains information about the ISM type and serial number. The label contains brief information about the VCB technical parameters. There...
