Abstract

The invention provides an electronic control mechanism for a circuit breaker closing device, which includes a prepaid opening circuit and a closing control circuit; the prepaid opening circuit includes first and second rectifying diodes and an opening processing circuit; the first rectifying diode After being connected with the outgoing line of the phase line, it is connected with the opening processing circuit; after being connected with the output control line of the ammeter, the second rectifier diode is connected with the opening processing circuit and the closing control circuit; the opening processing circuit is also connected with the opening coil for obtaining When the output signal level value of the second rectifying diode is 0V, the opening coil is controlled to be energized to realize the opening of the circuit breaker; the closing control circuit is also connected to the motor to obtain the level value of the output signal of the second rectifying diode greater than 0V , control the working mode of the motor, drive the sector gear to rotate and close, and realize the closing of the circuit breaker. By implementing the present invention, it is possible to intelligently control the circuit breaker to realize the opening and closing action according to the prepaid electricity fee of the electric meter user.

Description

technical field [0001] The invention relates to the technical field of a circuit breaker closing device, in particular to an electronic control mechanism of a circuit breaker closing device. Background technique [0002] With the development of my country's smart grid, under the premise of requiring the grid to operate safely, it is urgent to control electrical appliances intelligently. For example, the combined use of prepaid energy meters and prepaid miniature circuit breakers (such as MM7S and MM10S series products produced by Zhejiang Macleigh Electric Co., Ltd.) can allow electricity users to automatically cut off the power supply when the prepaid electricity fee is exhausted, so great It is convenient for the power supply unit to control the distribution of electric energy. However, after the user renews the fee, the user's circuit breaker cannot be automatically closed in time, and the user or the power supply staff need to manually operate, which brings inconvenienc...
