The invention discloses a high-voltage vacuum circuit breaker with high stability and easy to dissipate heat, which includes a case, the upper surface of the case is equidistantly installed with three solid-sealed poles from left to right, and the bottom end of the solid-sealed poles is A mounting plate is integrally formed, and the bottom surface of the mounting plate is embedded with a metal cover and an internally threaded pipe. The internally threaded pipe is connected to the upper surface of the chassis through bolts. The metal cover is provided with a spring, and the solid-sealed pole There is a cavity inside, and the left side of the solid-sealed pole is provided with a lower outlet pipe and an upper outlet pipe connected with the cavity, the upper outlet pipe is located on the top of the embedded pole, and the lower outlet pipe is located of the middle. The high-stability high-voltage vacuum circuit breaker that is easy to dissipate heat uses the cooperation of the heat dissipation plate, the heat dissipation through hole and the heat dissipation cavity to dissipate heat from the solid-sealed pole. malfunction occurred.
Description
technical field [0001] The invention relates to the technical field of high-voltage vacuum appliances, in particular to a high-stability high-voltage vacuum circuit breaker that is easy to dissipate heat. Background technique [0002] The high-voltage vacuum circuit breaker is named for its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum; the vacuum circuit breaker has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. It is widely used in distribution network. High-voltage vacuum circuit breakers generally include a chassis and poles. Among them, the poles include assembled poles and solid-sealed poles. The insulating shell of the vacuum interrupter of the assembled pole is exposed to the In the air, there is a problem of being polluted by dust and moisture from the outside. In order to reduce this effect, the outer shell of the vacuum interrupt...
