[0002] With the continuous expansion of power system scale, the reliability and stability of power equipment have become particularly important. As a key protective device in the power system, the circuit breaker plays a vital role in the normal operation of the power system. The automatic break-in controller of the circuit breaker can run in the key components inside the circuit breaker body to ensure its normal operation and extend its service life. Through automatic break-in, the failure rate of the mechanical system can be reduced and the overall operational reliability can be improved. Regular automatic break-in can reduce equipment failures caused by component wear, thereby extending the service life of the equipment. After break-in, the equipment operates more smoothly and its performance is more stable, reducing the performance degradation caused by insufficient component break-in. Traditional circuit breaker body maintenance methods have problems such as high labor costs and low efficiency. Especially under frequent operation, it is easy to cause accelerated wear of the circuit breaker body and affect its service life. Therefore, it is necessary to develop a device that can automatically control the circuit breaker body and improve its reliability.

[0021] Working Principle: When using this utility model, the automatic break-in controller body 3 is connected to the circuit breaker body 1 via a universal wiring harness 2. The universal wiring harness 2 includes cable assemblies connecting the controller to external devices (such as the circuit breaker body 1, sensors, etc.), featuring wide compatibility, standard connector types, and high-quality cables, facilitating installation and maintenance. The control unit 4 on the automatic break-in controller body 3 can automatically execute the operation of the circuit breaker body 1 according to a preset time interval or number of operations, including opening (tripping) and closing (closing) actions. It can also simulate the working state of the circuit breaker body 1 under normal operating conditions to test its response speed and reliability. For circuit breaker bodies 1 that require energy storage to complete opening and closing operations, the power module 5 can automatically complete the energy storage process and record relevant data to ensure the good operation of the energy storage mechanism.

The automatic break-in controller body 3 uses a position sensor to detect the open and closed status of the circuit breaker body 1 and transmits the data to the controller through the output module 6. It can promptly alarm in case of a fault. The power module 5 monitors the energy storage status and displays the energy storage status on the display screen. If necessary, the energy storage motor will be automatically started. The device is designed with an emergency braking button as a safety measure. Together with the high-brightness alarm light 9 and the manual operation module 10, it can quickly stop all operations of the controller and its connected equipment in an emergency, ensuring the safety of personnel and equipment. The communication module 8 is used to transmit information, sending the data collected by the control unit 4 and interacting with the user.
