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.
