Description
Technical field
The present invention relates to a kind of electric switch namely breakers.
Background technology
Existing electric switch, there are following some defects：One, the poles N are not provided with arc initiation device, when switch breaking current
When, because electric arc cannot guide to other positions or arc-chutes from moving contact and static contact, cause switch dynamic/static contact scaling loss serious,
Or even if being equipped with arc initiation device, but arc-chutes are not provided with, it causes electric arc to be stagnated for a long time in arc initiation device, product is caused to burn
Phenomenon is ruined or bursts, because the poles general circuit N cannot disconnect, but above-mentioned switch product, because dynamic/static contact scaling loss effectively causes electricity
Gas short life causes line broken circuit failure and other harm, cannot meet market demands；Two, L is extremely generally gone out using smaller
Arc chamber, or using upper and lower asymmetric arc-chutes, partly electric arc can not introduce arc-chutes caused by striking channel is small, cause
Switch product breaking capacity is low or bursts phenomenon, cannot meet circuit breaking capacity increasingly higher demands；Three, the poles L, N are extremely dynamic
Contact is separately fixed at the poles L, on the moving contact rack of the poles N, and then the poles L, the poles N moving contact rack are arranged in the both sides of lever, lock
It is also disposed on lever with tripping, organization volume is big at this time, and mechanism kinematic is dumb, and breaking speed is slow, the poles L, the poles N moving contact point
Not Wei Yu middle seat both sides up and down, because the poles L, the poles N moving contact rack are arranged in the both sides of lever, the poles mechanism section L cannot with the poles N
Isolation, electric arc and gaseous conductor are easy short circuit product are caused to burst product disjunction is made to fail when disjunction high current.And exists and divide
The risk that pressure resistance of having no progeny punctures, cannot meet user's requirement.
