The traditional small-sized breaker and switch opening and closing actions need to be completed by manual operation. With the development of smart power grids, small-sized circuit breakers and switch products capable of reliably realizing automatic switching on and off are urgently needed. Therefore, an electric operation device capable of driving opening and closing operations of a small-sized circuit breaker and a switch, which is used in cooperation with the small-sized circuit breaker and the switch, has appeared in the market. By sending instructions to the electric operating device, the miniature circuit breaker and the switch can be driven to automatically open and close without manual operation, thereby effectively saving manpower and material resources and being increasingly widely applied.
In the conventional small circuit breaker electric operation device, the trip linkage is in a free state or in a closed position relative to the circuit breaker. The technical defects are that firstly, when an electric operation device is assembled with a small-sized circuit breaker, the assembly is usually carried out in an off state, and whether the tripping linkage piece of the electric operation device is at an off position relative to the small-sized circuit breaker is uncertain under the condition that the tripping linkage piece of the electric operation device is in a free state, and errors are easy to occur during the assembly, so that poor working or damage is caused after the assembly; secondly, under the condition that the tripping linkage piece of the electric operation device is at a closing position relative to the circuit breaker, the assembly of the electric operation device and the miniature circuit breaker can only be carried out in a closing state, if the assembly of the electric operation device and the miniature circuit breaker is carried out in an opening state, errors occur during the assembly, and poor or damaged operation after the assembly is caused; finally, with the trip linkage of the electrically operated device in the closed position relative to the miniature circuit breaker, the trip movement of the miniature circuit breaker is affected when the miniature circuit breaker trips.
