Abstract
The present utility belongs to high voltage electricity distribution apparatus, relating to indoor integral separation switch which comprise a insulating shell with cylindrical internal chamber, main axle mounted at a insulating shell center, dynamic contact knife mounted on main axle and rotating with main axle, the dynamic contact knife being divided into upper arm and lower arm parts. Upper, lower and ground contact is inlayed in upper part, lower part and side part of internal wall of insulating shell. The upper contact connects wiring-in end with insulating material-wrapped upper conductor, while the lower contact connects wiring-out end with insulating material-wrapped lower conductor. Part of ground contact is in chamber of insulating shell, other part of is exposed outside of insulating shell. The present utility is compact and has good insulation performance.
Description
Technical field
The utility model belongs to the high pressure equipment for power transmission and distribution, relates to a kind of indoor integrated insulation switch.
