High voltage isolation vacuum circuit breaker embedded pole

Abstract

The invention discloses a high voltage isolation vacuum circuit breaker embedded pole comprising a vacuum arc-extinguishing chamber, an incoming wire conductive seat and an operating lever component,wherein the vacuum arc-extinguishing chamber is used as a central framework; the vacuum arc-extinguishing chamber and the incoming wire conductive seat fixed and linked in advance, and a voltage equalizing shield, a grounded screen metal net and multiple inserts that are preset are jointly placed into a gel mold in which pressure is preset; epoxy resin is used as a main material and integrally molded by vacuum pressure gel, and thus fixedly sealing is performed to acquire the needed embedded pole; the lower movable end of the vacuum arc-extinguishing chamber is linked with an outgoing wire conductive seat arranged on the lower end face of the cylindrical cavity via a preset conductive soft connection; the lower movable end of the vacuum arc-extinguishing chamber is in threaded connection with the operating level component arranged in the cylindrical cavity, and the operating level component stretches out of the lower end face of the cylindrical cavity to be linked with a preset isolation circuit breaker mechanism transmission chain; the embedded pole has the effects of being miniature, simplified, high in reliability and free of maintenance.

Description

technical field [0001] The invention relates to the field of high-voltage switchgear for control and protection in a high-voltage power transmission and distribution system, in particular to a solid-sealed pole of a high-voltage isolation vacuum circuit breaker. Background technique [0002] Since the 1990s, in the field of high-voltage switchgear, since the research results of vacuum arc theory have achieved substantial breakthroughs in large-scale engineering applications, a generation of miniaturized, highly reliable, environmentally friendly, material-saving and energy-saving vacuum switches has become so far. The mainstream products equipped with power transmission and distribution systems have produced huge social and economic benefits. However, as far as its overall structural design is concerned, it is still based on the traditional single-function basic theory and experience. Until the beginning of this century, through the efforts and exploration of our patentee t...

Problems solved by technology

However, in the early stage of structural design of the isolated vacuum circuit breaker pole (switch body) with multiple functions, limited by material technology, it still inherited the traditional insulating cylinder structure and air composite insulation method, which has a large volume and is affected by the working environment. The impact is obvious, the mechanical stability is weak, the pressure equalization and thermal conductivity are insufficient, etc.
