[0004] However, the electrical equipment maintenance system is usually set up on the workbench. Due to the small space underground in the mine, the traditional workbench takes up more space. In addition, the electrical equipment such as transfer transformers, power feeders, and comprehensive protection devices have long distances for daily leakage tests and power outages after failures. Each time the power is stopped, an electrician needs to be assigned to the head of the equipment train to deliver the transfer transformer and to the tail of the locomotive to deliver the lighting comprehensive protection device. Due to the long distance, it brings inconvenience to electrical maintenance and other maintenance work. Utility Model Content
