Bipolar hand wheel formula high voltage isolator

The utility model discloses a rotatory vase, high -voltage switch support, operation hand wheel, connection key, earthing pole, connection handle of a knife, handle of a knife interface and binding post, its characterized in that: be equilateral triangle between two rotatory vases on the high -voltage switch support and the earthing pole and arrange that every rotatory vase both can be connected with the earthing pole alone, also can two rotatory vases interconnect and be in the same place. Compared with the prior art, the utility model, obvious advantage and positive effect below having: 1. Normal during operation, two rotatory vases interconnect two the such connection handle of a knifes of being in the same place and simultaneously through the high tension current, have alleviateed their load, are favorable to improving the life -span, the high pressure eliminator supply stops work needed and overhauls often, and two rotatory vases can all be connected with the earthing pole, ensure constructor's safety. 2. The operation hand wheel is through connecting key and the continuous safe and reliable of rotatory vase, and is high to the bit rate.
