Patent for useful model №163178(4.6 MB)

Description

The utility model relates to electrical engineering, in particular to horizontal-type disconnectors, and can be used in complete distribution devices of high-voltage lines of the distribution network. The task of the utility model is to reduce the overall dimensions of the disconnector, expanding its functionality, ensuring the protection of electrical equipment insulation from the effects of atmospheric and switching overvoltages.

The technical result achieved by the claimed utility model is to reduce the overall dimensions of the disconnector, as well as ensuring the protection of electrical equipment from overvoltage.

The technical result is achieved by the fact that a disconnector containing a frame with one pivot and one fixed insulators, contact blades with contact, terminal leads according to the utility model, the fixed insulator is made of non-halogenated silicone rubber with end flanges and fiberglass cylinder leads, inside of which are placed metal-oxide varistors .
