电动铲运机以其噪声小、污染低、出矿量大及操纵方便而得到日益广泛的应用。然而,矿山井下的作业环境是高温、潮湿、多水以及有害气体和导电尘埃 浓度高,电动铲运机在这样的条件下工作很容易使设备的绝缘程度降低,导致电气设备经常发生漏电,引起设备烧毁及人身触电事故的发生。为了防止这些事故的发生,确保井下矿山移动设备的使用状况良好及操纵人员作业安 Electric scraper with its low noise, low pollution, a large amount of ore and easy operation and get more and more widely used. However, the working environment in the mine shaft is high temperature, humidity, water and high concentrations of harmful gases and conductive dust. Operating under such conditions, the electric scraper can easily reduce the degree of insulation of the equipment and cause frequent leakage of electrical equipment, causing Equipment burned and personal electric shock occurred. In order to prevent the occurrence of these accidents, to ensure that the underground mine mobile equipment is in good condition and operator safety
