Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new type of vacuum circuit breaker insulating sheath, which solves the problem that the sealing of the entire insulating shell is not strong, causing a large amount of water vapor and dust in the outside air to enter the interior of the insulating sheath , which will still cause some adverse effects on the joints of the vacuum circuit breaker, shortening the service life of the vacuum circuit breaker

Abstract

The invention provides a novel vacuum circuit breaker insulating sheath, and relates to the technical field of breaker protective sleeves. The novel vacuum circuit breaker insulating sheath comprisesa rear-end insulating sheath, the left side of the rear-end insulating sheath is fixedly connected with a front-end insulating sheath, the left side of the front-end insulating sheath is provided witha wire fixing component, the bottom of the rear-end insulating sheath is in threaded connection with an insulating sheath fixing seat, and the upper end of the insulating sheath fixing seat is in threaded connection with a protective nut. After the insulating sheath is assembled, a rubber strip clamping strip is clamped with a sealing rubber strip, so that the connection between the shells of theinsulating sheath has the good sealing performance, moisture and dust in external air can be effectively avoided, the joint of the circuit breaker is protected from being interfered, and the servicelife of the vacuum circuit breaker can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of circuit breaker protective sleeves, in particular to a novel vacuum circuit breaker insulating sheath. Background technique [0002] Vacuum circuit breakers can realize the isolation of large currents through the excellent insulation performance and isolation performance in high vacuum. In order to improve the safety performance of vacuum circuit breakers, insulating sheaths are generally installed on vacuum circuit breakers. It is a sharp tool for network insulation and power supply reliability. It can effectively prevent power outages and electric shock accidents caused by (human touch, small animals or sundries, acid rain and chemical gas corrosion) caused by exposed electrical connectors of power equipment. The degree of full insulation of the distribution network is continuously improved, and higher requirements are put forward for the structural rationality and configuration selection suitability of...
