Abstract
The utility model discloses an insulating box for a vacuum circuit breaker. The insulating box comprises a box body. Sidewalls on the two ends of the box body are connected with inlet wire guiding bushings. A cover plate is arranged on the top of the box body. Multiple heat-dissipating strip holes are distributed in the cover plate at intervals. An opening for an operating mechanism to pass through is arranged between one end of the cover plate and a sidewall of the box body. A positioning bracket used for installing a vacuum arc-extinguishing chamber is disposed at the bottom in the box body. A group of installing legs are disposed on the bottom of the box body and are provided with an integrated voltage equalizing wing plate. The insulating box for a vacuum circuit breaker has characteristics of simple and reasonable structure, easy installation and debugging, and good heat-dissipating performance. The design of arranging the voltage equalizing wing plate on the installing legs of the insulating box effectively improves the electric field environment between the insulating box and the housing of the vacuum circuit breaker, alleviates partial discharge, guarantees the stability of the vacuum circuit breaker, and prolongs the service life of the insulating box.
