Vacuum interrupter drive mechanism is provided with, the isolation blade installation axle is held to be connected between earthing static contact by isolating blade
Connect, and the side for isolating blade is connected by tripping mechanism with vacuum interrupter drive mechanism, the bottom of the isolation blade leads to
Insulated tension pole support clip fixed insulation pull bar is crossed, and is connected between insulated tension pole and earthing static contact by action bars.
Preferably, the bottom of the high-pressure vacuum switch support is fixed with support clip.
Preferably, second support insulator and the first support insulator are made up of ceramic material component.
Preferably, the action bars is connected by fastener with earthing static contact.
Preferably, the earthing static contact and earthing are made up of metallic material components.
Compared with prior art, the beneficial effects of the utility model are：The utility model is designed reasonably, it is simple in construction, lead to
Cross and action bars is separately fixed on earthing static contact and insulated tension pole, vacuum switch earthing that can link when disconnecting is quiet
Contact is touched on earthing, so as to which remnants electric charge fast and effectively is imported into the earth, and then further ensures electricity
The safety of power maintainer, vacuum switch and earthing is set to be combined as a whole, it is more perfect using function, while cause structure more
Step up to gather, using reliable, security performance is high, is easy to promote the use of.
