Disk type motor mechanism-based mine disconnecting switch breaking inspection system and method

Abstract

The invention discloses a mine disconnecting switch breaking inspection system and method based on a disc type motor mechanism, and the system comprises a controller which is connected with a power distribution module which is used for supplying power to a disconnecting switch; the current and voltage transformer module is used for detecting a current and voltage detection signal and feeding back the signal to the controller; a main shaft of the disc type motor mechanism is connected with a rotating shaft of the mine disconnecting switch, and the disc type motor mechanism is used for controlling breaking of the mine disconnecting switch; and the flashover detection circuit is used for detecting flashover signals generated by the mine disconnecting switch and feeding back the flashover signals to the controller. Through the arrangement of the current and voltage transformer module, the disc type motor mechanism and the flashover detection circuit, automatic detection of breaking of the mine disconnecting switch is realized, and the problems of low success rate, poor safety and the like caused by the fact that an existing detection system depends too much on experiences of experimenters are effectively avoided. For mine disconnecting switch life prediction, the influence of arcing time on the contact life during fault current breaking is comprehensively considered, and the prediction accuracy is high.

Description

technical field [0001] The invention relates to the field of breaking inspection of a mine isolating switch, in particular to a breaking inspection system and method for a mine isolating switch based on a disc-type motor mechanism. Background technique [0002] At present, my country's mine safety production situation continues to improve, and the total number of safety production accidents and death tolls are decreasing year by year. However, the mine safety production situation is still complex and severe, with unreasonable mine industrial structure, increased mining depth, increasingly serious disasters, uncertain external environment and personnel shortages. Factors such as insufficient experience and ability have brought hidden dangers of accidents to mine safety production. Electromechanical accidents refer to safety production accidents caused by equipment failures such as mining electrical appliances. In recent years, electromechanical accidents have become one of th...

Problems solved by technology

[0004] The existing isolating switch breaking test mainly adopts manual operation and pneumatic mechanism operation. Manual operation requires the tester to provide operating force for the action of the mine isolating switch. The test process requires the cooperation of two people. One tester is responsible for starting the breaking test system, and the other A tester pulls the rope to drive the rotating shaft of the isolation switch to complete the breaking test. This operation method relies too much on the experience of the tester, the test success rate is low, the safety is poor, and there are potential accidents.
