AI Technical Summary
When in use, existing circuit breaker boxes, especially at the connection between the extension copper strip and the conductor, may overheat due to current overload or poor contact, and cannot be properly cooled, which may lead to safety hazards such as fire or leakage.
A power circuit breaker box designed to prevent leakage current is used to achieve targeted forced heat dissipation by setting up structures such as elastic clips, sliding columns, air outlet slots and heat-conducting baffles. Combined with a high-pressure gas delivery system and a heat-sensitive metal sheet, the opening and closing of the gas channel is controlled to improve the stability of wire fixing and heat dissipation efficiency. The box is equipped with structures such as airbags and solenoid valves to ensure safety.
It effectively avoids loosening and overheating between the conductor and the extended copper strip, achieves targeted forced heat dissipation, reduces high-voltage gas consumption, improves the safe operation of the circuit breaker box, reduces the risk of short circuits, fires and leakage, and can extinguish fires in time in the event of spontaneous combustion.
