Abstract

The invention discloses a fixation and encapsulation pole for an all-condition intelligent vacuum circuit breaker. The fixation and encapsulation pole comprises an insulating encapsulation body and an insulating pull rod. A vacuum arc-extinguishing chamber is fixed and encapsulated in the insulating encapsulation body. The movable end of the vacuum arc-extinguishing chamber is connected with a sliding connecting piece. The insulating pull rod is located at the lower portion of the insulating encapsulation body. One end of the insulating pull rod is connected with the movable end of the vacuum arc-extinguishing chamber which is fixed and encapsulated, and the other end of the insulating pull rod is connected with an operating rod which extends out of the insulating encapsulation body. The fixation and encapsulation pole has the advantages of being simple and compact in structure, low in cost, wide in application range, capable of improving reliability and safety and the like.

Description

technical field [0001] The invention mainly relates to the field of high-voltage switchgear in an electric power system, in particular to a solid-sealed pole for an intelligent vacuum circuit breaker under all working conditions. Background technique [0002] In the field of high-voltage switchgear in power systems, high-voltage vacuum circuit breakers are the most widely used products in power transmission and transformation equipment. Vacuum circuit breakers have completely occupied the market of 40.5kV and below systems due to their high reliability of arc extinguishing performance, long life, and no pollution to the environment and human body, and have been favored by the majority of users due to their small size and anti-pollution recognized. [0003] However, according to incomplete statistics, accidents caused by external insulation have accounted for more than 50% of 40.5kV and below, so how to effectively ensure the insulation level of switches is one of the import...
