Abstract

The invention discloses a heat dissipation structure of a high-voltage and high-current vacuum circuit breaker. , the heat dissipation guide rod and the upper end cover of the vacuum circuit breaker are sealed by a shaft seal; it also includes a finned radiator arranged on the outer periphery of the lower flange and extending out of the outer edge of the lower flange, and the finned radiator is connected to the lower flange. The flange is integrally cast; this design can effectively increase the heat dissipation area of ​​the circuit breaker, reduce the temperature rise, and significantly increase the rated current of the high-voltage vacuum circuit breaker. The manufacturing process is simple, the cost is low, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of high-voltage circuit breaker heat dissipation, in particular to a high-voltage high-current vacuum circuit breaker heat dissipation structure. Background technique [0002] Currently in 126kV and above high voltage and extra high voltage circuit breakers SF 6 Circuit breakers are mainstream products. SF 6 The gas has been designated as a strong greenhouse gas by the "Kyoto Protocol", and it is recommended to completely ban SF in 2030 6 gas. Vacuum circuit breakers have the advantages of environmental protection and high product performance, and are currently the mainstream products in the medium voltage class. Replace SF with high voltage vacuum circuit breaker 6 A circuit breaker is a good option. Vacuum circuit breakers have outstanding capabilities in breaking short-circuit currents, but it is not easy to improve rated current parameters. Contents of the invention [0003] In order to overcome...
