INDUSTRIAL COMPUTER DISPLAY CONTROL DEVICE FOR MINE COMPREHENSIVE PROTECTION SYSTEM DETECTION DEVICE BY PLC

摘要

The invention patent relates a PLC type mine comprehensive protection system detection device industrial personal computer display and control device. With the PLC type mine comprehensive protection system detection device industrial personal computer display and control device adopted, the detection of the overload, phase failure, overvoltage, undervoltage and earth leakage lock-out of an electronic comprehensive protector in a mine comprehensive protection system can be realized, and the display and control of the detection of the synchronous pull-in time, withstand voltage and contact resistance of a vacuum AC contactor are also realized. A PLC is adopted as a main controller; an industrial personal computer serves as a display and control device; the display and control device is provided with electronic protector performance test and the vacuum AC contactor performance test buttons; an electronic protector performance test involves an overload, phase failure, overvoltage, undervoltage and earth leakage lock-out test display and control interface; and a vacuum AC contactor performance tests involves a synchronous time testing, insulation voltage and contact resistance test display interface. The device of the invention has the advantages of simple structure, convenient use, complete functions and reliable performance.
