Background

At present, the application of the power switch cabinet is very wide in power distribution facilities such as a transformer substation, an opening and closing station and the like. The power switch cabinet is divided into a switch cabinet and a handcart switch, and when power is cut off or power is transmitted, an operator pulls out or sends the handcart switch into the switch cabinet on the spot, so that the switch among a breaker overhaul state, a cold standby state and a hot standby state is realized. The opening and closing operation of the circuit breaker is operated by an operator at a remote place.

When the breaker is closed, the opening spring keeps the stored energy state. The handcart switch brake-separating relay is enabled to act through a remote (or local) brake-separating command, the charged brake-separating electromagnet releases the stored energy state of the brake-separating spring through the striker, and the breaker is disconnected by using the energy released by the brake-separating spring.

When any link between a remote (or local) tripping signal and a firing pin of the opening electromagnet has a problem, the electric opening operation of the circuit breaker cannot be realized. For this purpose, a mechanical tripping button is arranged on the tripping spring. The operator can also release the stored energy state of the opening spring by pressing the button, thereby disconnecting the switch.

However, in the process of the switch cabinet running with load, when the auxiliary switch of the breaker fails and the opening coil fails, the breaker cannot be electrically opened, and meanwhile, under the condition of unknown reasons, the mechanical opening button is pressed to try to open the breaker emergently, so that great potential safety hazards exist, not only explosion of equipment is possible, but also injury to operators is caused. Therefore, the existing method can only stop the bus where the switch cabinet is located, and after the load is thrown off, the maintainer enters the fault switch cabinet to perform on-site brake opening. Although the existing processing method can also solve the fault, the power failure range is expanded, the power supply reliability is reduced, and the people power supply service acquisition feeling is reduced.
