The invention discloses an automatic brake switching and closing operation device comprising a shell, a handle device, a handle driving member, a circuit board and a motor. The circuit board is fixedly arranged relative to the shell. One side surface of the circuit board is provided with a state detection sensor, and the other side surface is provided with a brake switching detection sensor and a brake closing detection sensor which are arranged in a spacing way. The handle device is provided with a first magnet and can move between a brake switching position and a brake closing position so as to drive the first magnet to be inductive to the brake switching detection sensor or the brake closing detection sensor and detect the brake switching position or the brake closing position. The handle driving member can drive the handle device to move and can be separated from the handle device. The handle driving member is provided with a second magnet which is inductive to the state detection sensor so as to detect the free state of free rotation of the handle device relative to the handle driving member. The motor is connected with the circuit board in a signaling way and connected with the handle driving member through transmission so as to accurately control the brake switching and closing state and the free state and drive and realize automatic brake switching and closing control of a circuit breaker.
Description
technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an automatic opening and closing operation device. Background technique [0002] With the development of the technical level, in order to meet the different electricity demands of users, the smart grid develops rapidly, so the demand for smart appliances is more and more extensive. [0003] For example, the demand for automatic opening and closing of miniature circuit breakers is becoming more and more urgent. However, most of the prepayment functions existing on the market are prepaid electric meters and prepaid miniature circuit breakers used in conjunction with each other, so that the miniature circuit breaker automatically disconnects the circuit when the electricity charge is zero. However, after the renewal, it cannot automatically close the switch to connect the circuit, but requires staff or users to manually close the switch, which cannot meet the needs of the ...
