Abstract

The invention provides a novel vacuum circuit breaker insulating sheath, which relates to the technical field of circuit breaker protective sheaths. The novel vacuum circuit breaker insulating sheath includes a rear insulating sheath whose left side is fixed Connected with a front-end insulating sheath, the left side of the front-end insulating sheath is provided with a wire fixing assembly, the bottom of the rear-end insulating sheath is threaded with an insulating sheath fixing seat, and the upper end of the insulating sheath fixing seat is threaded Attached with protective nut. After the insulating sheath is assembled, the rubber strip and the sealing rubber strip are clamped, so that the connection between the insulating sheath shells has a good seal, which can effectively prevent moisture and dust in the outside air and protect the The joint of the circuit breaker is not disturbed, which can effectively prolong the service life of the vacuum circuit breaker.

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] The vacuum circuit breaker can realize the isolation of large current through the excellent insulation performance and isolation performance in vacuum. In order to improve the safety performance of the vacuum circuit breaker, an insulating sheath is generally installed on the vacuum circuit breaker. The insulating sheath is to improve the distribution network. A sharp tool for insulation and power supply reliability, it can effectively prevent power outages and electric shock accidents caused by (human touch, small animals or sundries lapping, acid rain and chemical gas corrosion) on the electrical connectors of exposed power equipment. The degree of network insulation is continuously improved, and higher requirements are put forward for the structural rationality and config...
