[0002] Breaker running-in is an important step in ensuring the safe operation of the power system, and reclosing operation is an indispensable part of this work. The break-in test simulates the process of the circuit breaker quickly disconnecting the fault current and then automatically closing and putting it into operation when a fault occurs in the power system, so as to assess the dynamic and static characteristics of the switch during reclosing and its overcurrent tolerance. Through break-in, the switch can gradually reach its optimal state and play its maximum role, thereby extending the life of the equipment and ensuring the safe operation of the power system.

The number of running-in times and speed are restricted by the movement speed of the cylinder, the running-in speed is slow, and the running-in cycle is long. Therefore, it is necessary to design a switch running-in mechanism driven by a motor cam to replace the traditional cylinder push-pull running-in method, increase the number of running-in times per unit time, and shorten the switch running-in cycle.
