ZN28-12K/630-25 type product is manufactured by introducing German company SIEMENS technology. The circuit breaker Operating mechanism is spring stored energy type, can be used in AC / DC operation, manual operation. It is applicable to controlling and protecting of transmission and distribution system such as power plant and substation, especially to disconnecting the important load and frequent operation places.
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.
