Structure and Function

GPL(R) type switch consist of operating mechanism and arc-extinguish chambers in front-back arrangement, its main conductive circuit is of floor model structure. The vacuum arc-extinguish chamber is fixed in a vertical cannular insulation column structure made of epoxy resin by APG technology, therefore with very good anti-creepage Such structure design great that reduces the accumulation of dusts on the surface of vacuum arc-extinguish chamber, it not only can prevent the vacuum extinguish chamber from outside influence, but also can ensure to present high resistance state against the voltage effect even in warm-wet climate or heavy pollution environment.

The spring operating mechanism arranged in plane disposal can be charged by manual or motor, the operating mechanism located in the iron box fixed in front of arc-extinguish chamber. The box is divided into five assembly space by four clapboards, in this space there are charging section, diving section, releasing section and buffer of mechanism separately. The structure of GPL(R) type switch which the operating mechanism and arc-extinguish chambers are arranged into an integrate front-back layout can match well the operating performance of operating mechanism and the performance needed for breaking and making of arc-extinguish chamber. Also, can reduce the needless midway terms and reduce the noise and energy consumed therefore to lead the operation performance of GPL(R) much reliable.
