Product Description

ZW7-40.5 series outdoor high voltage AC vacuum circuit breaker is 3 phase AC 50Hz 

outdoor high voltage Switchgear;Equips the CT19BW type spring operating device spring 

actuator,applies to control and protect of 35kv power transmission and distribution system;

This product has the advantages of the big breaking capacity,safe and reliable operation,

frequent operation,low maintenance and so on;Also could be used in the places of the networkinterconnecting circuit breaker,open/close capacitor bank.


The working principle of the Vacuum Circuit Breaker is: When the moving and static contact in the Operating mechanism under the action of the gate, the contact between the arc, the contact surface at high temperature volatile steam, the contact design for the special shape, Through the magnetic field generated when the arc under the action of the magnetic field along the contact surface tangential direction of rapid movement in the metal cylinder (shield) on the condensation of some metal vapor, the arc in the natural zero-crossing, the contact between Medium strength and quickly recover.
