Problems solved by technology
[0002] The existing communication cabinets or intelligent control cabinets all need automatic control and remote control functions. For the convenience of control, contactors are basically used for control. However, due to infrequent operations, using contactors has the disadvantages of high energy consumption and high cost. shortcoming
If the contactor is replaced with an electrically operated circuit breaker, both will need to be equipped with an electrically operated device, which will be more costly

The invention relates to an electric operating device of a circuit breaker. The electric operating device comprises a shell, wherein a transmission mechanism is installed in the shell, one side wall of the shell serves as an operating surface and is provided with a first sliding groove communicated with the interior of the shell, a sliding rod is installed in the shell, the sliding rod is providedwith a driving piece controlled by the transmission mechanism, the driving piece is provided with a closing operation part and an opening operation part, the driving piece penetrates through the first sliding groove and extends out of the shell, the driving piece moves along the sliding rod under the control of the transmission mechanism, and the closing operation part and the opening operation part operate the handle of the circuit breaker to be closed and opened respectively. According to the invention, the sliding rod for providing the motion trail for the driving piece is arranged in theshell, so that the driving piece operates the closing and opening of the circuit breaker through the closing operation part and the opening operation part in the process of moving along the sliding rod; and the closing operation part and the opening operation part can be widened according to the number of the handles of the circuit breaker, so that one electric operation device can operate the handles of a plurality of circuit breakers.
Description
technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an electric operating device for a circuit breaker. Background technique [0002] The existing communication cabinets or intelligent control cabinets all need automatic control and remote control functions. For the convenience of control, contactors are basically used for control. However, due to infrequent operations, using contactors has the disadvantages of high energy consumption and high cost. shortcoming. If the contactor is replaced with an electrically operated circuit breaker, both will need to be equipped with an electrically operated device, which will be more expensive. Therefore, it is very necessary to design a device that can control multiple handles of multiple miniature circuit breakers by one electric operating mechanism through the cooperation of other installation devices to reduce the energy consumption and cost of the communication cabinet or intel...
