A multi-plate high thermal conductivity high voltage vacuum circuit breaker

Abstract

The invention discloses a high-voltage vacuum circuit breaker with high heat conduction of multiple plates. Fastened with the connecting cover plate, when the equipment is in use, through the multi-plate heat dissipation mechanism, the present invention can realize the avoidance that the high-voltage circuit breaker is easily affected by high temperature. The existing equipment is usually in the static state of the vacuum interrupter. Installing a radiator at the end requires a separate power supply system, which is troublesome to install and has a limited heat dissipation effect. However, there are many heating elements in high-voltage circuit breakers, and the existing equipment cannot effectively conduct heat and dissipate heat for high-voltage circuit breakers in a targeted manner, so as to affect the normal operation of the equipment. It will have a certain impact on the problem, so that the equipment can conduct heat conduction to the internal heat in a targeted manner, reduce the trouble of installing redundant equipment and be more targeted, and the heat dissipation of the main body of the circuit breaker is more complete.

Description

technical field [0001] The invention is a multi-plate high-thermal-conduction high-voltage vacuum circuit breaker, which belongs to the field of circuit breakers. Background technique [0002] High-voltage vacuum circuit breaker is a kind of high-voltage switchgear widely used in distribution network. Because it can reliably extinguish the arc when it is frequently broken, it has high safety. It can be used as electrical equipment in industrial and mining enterprises, power plants, and substations. It is used for protection and control, especially suitable for places requiring oil-free, less maintenance and frequent operation. [0003] The existing technology has the following disadvantages: because the high-voltage circuit breaker is easily affected by high temperature, the existing equipment usually installs a radiator at the static end of the vacuum interrupter, which requires a separate power supply system, which is troublesome to install and has a limited heat dissipati...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a multi-plate high-thermal-conduction high-voltage vacuum circuit breaker to solve the problem that the existing equipment is usually installed in a vacuum interrupter because the high-voltage circuit breaker is easily affected by high temperature. Installing a radiator at the static end of the high-voltage circuit breaker requires a separate power supply system, which is cumbersome to install and has limited heat dissipation effects. However, there are many heating elements in high-voltage circuit breakers, and the existing equipment cannot effectively conduct heat and dissipate heat for high-voltage circuit breakers in a targeted manner. Normal work will have a certain impact on the problem
