Outdoors On Pole vacuum circuit breaker

1 Purpose and Usage
Outdoors AC high voltage vacuum circuit breaker of Model ZW32-12 (hereinafter referred to as circuit breaker) is an outdoors three phase AC distribution equipment of 12kV, 50Hz. It is mainly used to close and open the load current, overload current and short circuit current in the distribution net. It can be used electric substation, industrial and mining establishments' distribution systems as protector and controller, especially be suitable for the electric power net reconstructions of urban and countryside. 2 Features
1The circuit breaker adopts the frame of three poles brace. It has characters of reliable capability of open circuit, no danger of burning or explosion, non-maintenance, compactness, low weight, long service life, etc.
2The circuit breaker has whole sealing structure and good sealing performance, which help it to proof moisture and condensation. It can be used in high temperature, low temperature and moist consitions.
3The operating mechanism adopts miniaturized spring-control mechanism with low energy consumption. The drive mechanism adopts direct transmittal mode to reduce acting parts and improve dependability. The operating mechanism is in a sealed mechanism case, resolving the problem of corrosion and probing dependability.
4The action of open circuit and close circuit can be acted by manual, electric or remote means. It can automatically distribute by matching the controller. It can form automatic circuit re-closer or sectionalizer with re-close controller.
5Two-phase or three-phase CT can be installed on the circuit breaker for the current automatic release protection and for the intelligent controller to analyze the information. CT can be installed according to customer's demand.
6Isolating switch or three-phase linkage can be installed. Visible fracture appears in isolating switch open mode. It has mistake-proof interlock with the noumenon of the circuit breaker. Lightning arrester post isolator can be installed. It can be maintained easily and safely.
7Weight of the circuit breaker: 80Kg (without isolation); 95Kg (with isolation).
