Abstract

See full text

The present invention discloses a protection module for a control and protective switching device, comprising a control power supply processing unit, an auxiliary power supply processing unit, a power supply converting unit, a signal processing and controlling unit, a trip electromagnet driving unit, a control electromagnet driving unit, and a man-machine interaction device. The control power supply processing unit and the auxiliary power supply processing unit receive a power supply signal from a high voltage power supply, and process the signal for supplying power for other components. The signal processing and controlling unit receives a mutual-induction signal from a current mutual inductor, outputs a first control signal and a second control signal to the trip electromagnet driving unit and the control electromagnet driving unit, and receives a first feedback signal and a second feedback signal from an operation mechanism and a control electromagnet. The trip electromagnet driving unit outputs a first operation signal to a trip electromagnet, and the trip electromagnet outputs a mechanical signal to the operation mechanism. The control electromagnet driving unit outputs a second operation signal to the control electromagnet. The man-machine interaction device performs signal interaction with the signal processing and controlling unit.
