High voltage vacuum circuit breaker

Abstract

The invention discloses a high-voltage vacuum circuit breaker. The high-voltage vacuum circuit breaker comprises a spring mechanism box. The spring mechanism box is communicated with a plurality of column-type insulation shell bodies. Each column-type insulation shell body is internally provided with a vacuum arc-extinguishing chamber. One end of a static conductive rod runs through the upper end of the vacuum arc-extinguishing chamber, and the other end is connected with an upper line-outgoing terminal; one end of a moving conductive rod runs through the lower end of the vacuum arc-extinguishing chamber, and the other end thereof is connected with a lower line-outgoing terminal; each vacuum arc-extinguishing chamber is externally covered by a translucent cover; the inner walls of the translucent cover and the outer walls of the vacuum arc-extinguishing chamber are enclosed to form an enclosed space, and the enclosed space is internally filled with colored gas; and each column-type insulation shell body is provided with a maintenance door. The high-voltage vacuum circuit breaker solves the problems that a common vacuum circuit breaker is enclosed, so that it is hard to carry out maintenance on the vacuum arc-extinguishing chamber therein and to observe whether the inner vacuum state is destroyed.

Description

Technical field [0001] The present invention relates to power equipment, in particular, to a high-voltage vacuum circuit breaker. Background technique [0002] The vacuum circuit breaker is named after its arc extinguishing medium and the insulating medium of the contact gap after the arc extinguishing are high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no need to overhaul the arc extinguishing. Chinese applications are more popular. The vacuum interrupter is equipped with a vacuum interrupter. The interior of the vacuum interrupter must be completely vacuumed. When the vacuum interrupter is damaged or leaks after long-term use, the vacuum circuit breaker will fail, while the general vacuum circuit breaker They are all airtight, it is difficult to overhaul the internal vacuum interrupter and observe whether the internal vacuum state is damaged. [0003] Therefore, providing a high-voltage vacuum circuit breaker capable of quick...
