一、电机烧毁和保护现状电机是煤矿井下使用的主要动力设备,特别是中小型交流感应电动机所占数量更多,因此,如何使电机不被烧毁和少被烧毁是个值得重视的问题。但是,目前电动机烧毁非常严重。根据“江西省煤矿电机烧损情况调查报告”中对部分煤矿的调查结果,每生产一万吨煤炭平均烧毁电机达1.66台,这是十分惊人的。电动机烧毁不仅损失设备本身的价值,更重要的是造成停产而影响煤炭生 First, the motor burned and protection of the status quo Motor is the main power plant used in coal mines, especially the small and medium AC induction motor account for a greater number, therefore, how to make the motor is not burned and less burned is a problem worthy of attention. However, the motor is currently burned very seriously. According to the Survey Report of Coal Mine Electrical Burning in Jiangxi Province, the survey results of some coal mines show that each production of 10,000 tons of coal burns an average of 1.66 motors, which is quite alarming. Burning motor not only the loss of the value of the equipment itself, more importantly, the production is cut off and affect the health of coal
