Overview

If a grounding fault occurs in the line connected to the 10KV outdoor circuit breaker on the primary and secondary fusion column, and the circuit breaker trips, but the grounding fault point is not cleared, the insulation of the busbar to ground should also be borne by the vacuum gap of the circuit breaker fracture; When various faults are disconnected, the vacuum insulation gap between a pair of contacts on the fracture surface should withstand the effects of various recovery voltages without breakdown.

Complete set of high-voltage vacuum circuit breakers on the primary and secondary fusion columnsAs a common outdoor high-voltage circuit breaker, there are the following mainstream models:

ZW32-12/630-20, ZW32-12/T630-25 (spring operated mechanism)

ZW32－12／1250－20，ZW32－12／T1250－25，ZW32－12／1250－31．5

ZW32－12／T2000－25，ZW32－12／2000－31．5

The main body of the high-voltage vacuum circuit breaker is composed of a conductive circuit, an insulation system, sealing components, and a housing. The overall structure is a three-phase common box. Among them, the conductive circuit is composed of incoming and outgoing conductive poles, incoming and outgoing insulation supports, conductive clamps, flexible connections, and vacuum arc extinguishing chambers. The mechanism is mainly used for electric energy storage, electric opening and closing, and also has manual functions. The entire structure consists of closing springs, energy storage systems, overcurrent release devices, opening and closing coils, manual opening and closing systems, auxiliary switches, and energy storage indicators.
