AI Technical Summary

Technical Problem

In rainy weather outdoors, the vacuum circuit breaker in the center cabinet has a lower heat dissipation efficiency due to the enhanced sealing effect, which brings inconvenience to use.

Method used

A multi-plate high thermal conductivity vacuum circuit breaker was designed. It uses a lifting rod and a collection cover to collect rainwater. Through the combined structure of guide grooves and heat dissipation holes, combined with extended waterproof plates and heat dissipation plates, rainwater guidance and heat transfer are achieved, preventing rainwater intrusion and improving heat dissipation efficiency.

Benefits of technology

It effectively prevents rainwater from intruding into the circuit breaker cabinet on rainy days, and at the same time improves heat dissipation efficiency through heat conduction and air convection, ensuring that the circuit breaker can operate normally under severe weather conditions.

Abstract

The present invention discloses a multi-plate high thermal conductivity vacuum circuit breaker, including a circuit breaker cabinet for heat dissipation protection of the circuit breaker body, wherein a lifting rod is vertically limited and slidably connected to the upper portion of the circuit breaker cabinet, and a collection cover for collecting rainwater is passed through and fixedly connected to the top of the lifting rod, and a drop hole is provided on the top of the lifting rod to guide the rainwater collected in the collection cover to fall, and a guide groove is provided on the upper surface of the circuit breaker cabinet to guide the flow of rainwater falling from the drop hole, and a heat dissipation hole is provided on the side of the circuit breaker cabinet for transferring and circulating hot air in the circuit breaker cabinet. The present invention, through the coordinated use of the above structures, solves the problem that in actual use, due to the fact that in order to prevent rainwater from intruding in rainy weather outdoors, the sealing effect of the cabinet body such as the central cabinet is strengthened, thereby reducing the heat dissipation efficiency of the circuit breaker in the central cabinet and causing inconvenience in use.
