Abstract
The utility model discloses an insulating sleeve for a vacuum circuit breaker. The insulating sleeve comprises a sleeve body with openings on the two ends thereof. Insulating sheds are distributed on the outer wall of the sleeve body. A sealing cover is installed on the top of the sleeve body. A pedestal is installed on the bottom of the sleeve body. A wire hole is disposed on the sealing cover. A limiting step hole used for cooperating with an insulating pull rod is disposed on the pedestal. An inlet wire guiding sleeve is disposed on the outer wall on the lower end of the sleeve body and close to the pedestal. A ripple insulation lining is arranged on the inner wall of the sleeve body. The insulating sleeve for a vacuum circuit breaker has characteristics of simple and reasonable structure and easy installation and debugging. The design of arranging the ripple insulation lining in the insulating sleeve effectively improves the electric field environment of the inner wall of the insulating sleeve, alleviates partial discharge, guarantees the stability of the vacuum circuit breaker, and prolongs the service life of an insulating box.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker, is specially a kind of vacuum circuit-breaker insulating sleeve.
Background technology
