Drum shearer electrical module detection test bed and detection method

Abstract

A drum shearer electrical module detection test bed comprises a main control box and an electrical detection module. The main control box comprises an indicating lamp, a display screen, a button switch, a signal generator, an analog potentiometer, an EPU module detection interface, a motor controller module detection interface and an electric leakage detection module interface. The electrical detection module comprises an EPU module, a motor protector module, an electric leakage detection module, a communication cable, a coupling module, a signal converter module and a main controller IPC module. The EPU module comprises a motor protector module, a current transformer and a vacuum contactor; the signal generator is connected to a shearer to-be-tested module through a wire, and the signal converter module and the coupling module are sequentially connected to the shearer to-be-tested module; the signal converter module is connected with the EPU module, the motor protector module and theelectric leakage detection module and then connected to the main controller IPC module. According to the detection method, whether each shearer electrical module is normal is detected, and the fault processing capacity is improved.

Description

Technical field [0001] The invention relates to a test bench for detecting electrical modules of a drum shearer and a detecting method. Background technique [0002] With the continuous improvement of mine production equipment conditions, the requirements for the reliability of large-scale fully-mechanized mining electrical equipment increase, and the fault detection technology of the drum shearer becomes more and more important. In order to ensure the normal operation of the drum shearer in the fully mechanized mining face, improve production efficiency, and prevent the shearer from delaying production due to the failure of the electronic control part, the fault detection of the electronic control part is increased, especially the inspection before the overall assembly. It seems very urgent. Drum shearer electrical modules mainly include isolation switch module, vacuum contactor module, current transformer module, power supply module, main control module STS, analog module HMA,...
