Product Description

ZN85-40.5/2000-31.5 type VCB adopt module spring Operating mechanism is used for the breaker. simple,mature,robust and convenient,the mechanism adds to the reliability of circuit breaker`s performance,and allows frequent operations or multiple breaks of the short-circuit current within the range of the operating current.


ZN85-40.5/2000-31.5Vacuum Circuit Breaker, vacuum, when the dynamic and static contact in the operating mechanism under the action of electric trip, the contact will produce a vacuum arc, and because of the special structure of the contact, the gap in the contact Also produce the appropriate longitudinal magnetic field, to promote the vacuum arc to maintain the diffusion type, and make the arc evenly distributed in the contact surface combustion, to maintain a low arc voltage, current zero crossing, the residual ions, electrons and metal vapor in the micro Sec order of magnitude within the time can be compounded or gathered in the contact surface and shield, interrupter dielectric fracture strength of the fracture is quickly restored, so the arc was extinguished to achieve the purpose of breaking, the vacuum circuit breaker using magnetic field control Vacuum arc, which has a strong and stable breaking current capacity.

 

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.
