ZN28A-12/630-25 series Vacuum Circuit Breaker is the indoor high voltage Switchgear with 12kV rated voltage , three phase AC 50HZ . It is mainly used for fixed type switch cabinet or substituting minimum oil circuit breaker in old-fashioned kinds, also applies to protecting and controlling unit of mobile switching equipment. It is suitable for occasions with frequent operation.
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.
