1.Summary
ZW32-12 type outdoor high-pressure vacuum circuit breaker (hereafter referred to as the circuit breaker) ,It is the outdoor high-pressure switching equipment of the three-phase alternating current 50Hz, 12KV, are used in on-off, turn off and shut the load current, overcurrent and short circuit current in the electric system, place that is suitable for frequently operating.
The matched CTB spring operating mechanism of the circuit breaker, can realize electronic stored energy, electronic divide-shut brake, stored energy and manual divide-shut brake that can also be manual.
The circuit breaker has surge control function of switching-in, meet and control and measure the requirement, mix the electronic control unit, can realize & ldquo; Four distant & rdquo; Control.
The circuit breaker is the oilfree first-selected products that are reelected of urban and rural power grids.
2.Normal service conditions
