Analysis and Handling of Common Electrical Faults in Electric Traction Coal Mining Machine
As a key equipment for underground production in coal mines,ensuring the operating rate of the coal mining machine is crucial for improving the quality and efficiency of coal mine production.This article takes the MG250/600-QWD electric traction shearer used in the 10805 working face of Erhai Coal Mine of Qianxi City Erhai Mining Co.,Ltd.as the analysis object,analyzes the operating principle of the electrical system of the shearer,and focuses on the common problems in the electrical part of the shearer,such as the inability to start the main engine or self-protection after starting,the failure of the rocker arm,and the inability of the traction frequency converter to be powered on normally Targeted maintenance and handling measures have been proposed for common faults such as motor faults,combined with the operation practice of coal mining machines.This has certain reference significance for electrical faults similar to coal mining machines.
