ZN63A(VS1)-12, 11kV, 4000A VCB adopts integral design. Its spring Operating mechanism is very mature, simple, reliable. The Vacuum Circuit Breaker box is divided into several function units, which brings easy maintenance. It is widely used in power distribution and transforming systems of power stations, power generators, mines, industries, airport, subways, and residential area.Compared with VD4, VS1 type VCB has more competitive price.
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.
