The circuit breaker comprises a contact, a release, a rotary operating handle and other components, and the contact is mechanically linked with a circuit breaker main circuit opening and closing mechanism and is mainly used for displaying the opening and closing state of the circuit breaker, and is connected in a control circuit of the circuit breaker to control or interlock related electric appliances through opening and closing of the circuit breaker. The trip unit is a device mechanically coupled to the circuit breaker for releasing the hold-down mechanism and automatically opening the circuit breaker. The rotating operation handle is a structure which is in transmission connection with the release and used for manual and automatic pushing to reconnect, generally arranged outside the shell of the circuit breaker, and the push rod of the motor operation structure arranged on one side is in transmission connection with the operation handle, so that the effect of automatic control superposition is realized. As can be seen from fig. 1 and 2, the automatic reclosure 2 is composed of two parts, namely a circuit breaker with a control lever, and a motor operating mechanism with an arc-shaped cover arranged outside.

In order to achieve the effect of remote control, a separate communication module is further arranged on one side of the motor operation structure, and stable and low-power-consumption communication equipment needs to be adopted in consideration of the fact that the equipment can be used for a long time and cannot be frequently maintained on site.

However, even in a terminal device with low power consumption, heat is generated even after long-term use, and if communication is blocked in a short time or the data amount is large, the internal temperature of the communication module is increased, and electronic components may be affected unless heat is dissipated.
