Environmental-friendly novel pre-assembled vacuum switch pole

Abstract

The invention discloses an environmental-friendly novel pre-assembled vacuum switch / vacuum circuit breaker pole, the pole comprises an assembly casing formed by a cover plate and an insulating casing, a vacuum arc-extinguishing chamber is fixed between the cover plate and the insulating casing, one end of the vacuum arc-extinguishing chamber is connected with an insulating pull rod, the other end and a static end bus are fixed to the insulating casing, and a movable end bus outlet is arranged on side wall of one end corresponding to the insulating pull rod on the insulating casing. Two ends of the vacuum arc-extinguishing chamber respectively comprise protruding portions, a protruding portion on one end is connected with the insulating pull rod, and a copper gasket is arranged between a protruding portion on the other end and the static end bus. According to the invention, the insulating casing is pre-assembled, element interchangeability is high, finished product utilization rate is improved, and the pole has advantages of environmental friendly, no maintenance, high reliability, low cost, light weight and the like.

Description

technical field [0001] The invention relates to a vacuum circuit breaker, in particular to an environmentally friendly novel pre-installed vacuum switch pole. Background technique [0002] The vacuum circuit breaker is one of the core components of the circuit breaker unit of the gas-filled ring main unit, and the pole of the vacuum circuit breaker is responsible for the positioning and insulation of the vacuum interrupter. High efficiency, environmental protection, simple structure, greatly reducing the cost of the core components of the ring main unit; good stability, which helps to improve the mechanical characteristic parameters of the vacuum circuit breaker. Research on a new environmentally friendly vacuum circuit breaker pole can reduce manufacturing costs. [0003] The existing solid-sealed pole generally consists of an insulating pull rod, a flexible connection, a lower outlet terminal, an epoxy resin shell, and an upper outlet terminal. This product satisfies the...
