(ZEp TAVRIDA ELECTRIC Excellence in Engineering VACUUM CIRCUIT BREAKER

This User Guide describes the Vacuum Circuit Breakers manufactured by Tavrida Electric. Tavrida Electric circuit breakers are designed for rated voltages up to 24 kV. Vacuum Circuit Breakers described in the current document can be used in various kinds of switchgear and RMUs and are intended to perform switching operations in network rated and faulty modes. The breakers are comprised of following main components: • Indoor Switching Module (ISM) - The air insulated ISM incorporates Tavrida Electric vacuum interrupters with monostable magnetic actuators and solid dielectric insulating...

Table 1 - Main technical parameters 1) For VCB ISM15_Shell with Low upper terminal - up to 1250 A, with High upper terminal - up to 2000 A. 2) Rating for metal enclosed switchgear with limited ventilation. Temperature rise type test at 2500 A in Cradle was successfully passed in KEMA. 4) The information in brackets refers to the national Chinese standards GB1984-2003 and installation altitude of maximum 1000 m. 5) Parameter valid only when ISM is used with insulation kit. For details see dimensional drawings and accessory information. 6) Parameter valid only when ISM is used with insulation...

The number of sequential Close-Trip operations with interval 10 seconds should not exceed 10. The number of Close-Trip operations should not exceed 60 per hour. Sequence of 10s Close-Trip operations can be repeated only after 260 s pause. At Cos j >0.66. At Cos j >0.33. Up to an installation altitude of 1000 m above sea level. Above 1000m, the external insulation measurement of the ISM must be increased by the atmospheric correction factor Ka according to IEC 62271-1 compared to the insulation measurement at sea level. The maximum allowed altitude is 2000 m above sea level. 1.3 Disclaimers...

The Vacuum Circuit Breakers itself does not have nameplates or seals but main components (ISM, CM and manual generators) it is comprised of have them. ISM nameplates and seals Each ISM has the following plate and labels:    Label Serial number plate Seals Manufacturer Rated voltage Ur Rated power frequency withstand voltage Vd Rated impulse withstand voltage Up Applicable standards ISM designation Rated duration of short circuit tk Rated short-circuit current Isc Rated normal current Ir Phase center distance p Weight W Year of manufacturing Rated operating sequence The serial number...
