The battery and the emergency busbar can be disconnected by controlling the switch, but most of the batteries and the battery direct busbar of the aircraft do not have control switches for safety requirements, and are directly connected, so that the connection between the battery and the direct busbar cannot be directly disconnected, and the power supply of the equipment on the busbar cannot be directly disconnected. In low temperature weather, the nickel-cadmium battery pack commonly used by the aircraft needs to be removed for heat preservation treatment, and the heat preserved battery pack is installed before the flight of the aircraft to ensure sufficient power of the battery during the flight. At the same time, when the battery fails, the normal battery cannot be quickly replaced.

This brings the operation of replacing the battery, which needs to disconnect and restore multiple circuit breakers multiple times, and the operation is complicated, the low temperature working time of the aircraft maintenance personnel is increased, the working intensity is increased, and the thermal circuit breaker is mainly used for the protection of the circuit of the aircraft and cannot be used as a control switch. Frequent operation will cause the reliability of the thermal circuit breaker to decrease, the service life of the thermal circuit breaker to decrease, and additional operation cost to increase. When the aircraft dismounts and mounts the battery, misoperation is easy to cause the ablation of the battery terminal post. SUMMARY
