【Abstract】 There are safety hazards in the long-term operation of explosion proof electrical equipment in the harsh environment of the mine. In order to predict the operation reliability of key components and structures of mine explosion-proof electrical equipment, it uses posWeibull software to establish four fault component data tables respectively to verify the life distribution, and uses Weibull distribution to effectively model the failure process of explosion-proof motor, The reliability curve of key components is drawn, and the average life of the motor is predicted. It is pointed out that the service life of motor obeys Weibull distribution, and strengthening the reliability of winding components can effectively improve the service life of motor.更多还原
