Application of low voltage DC/AC inverter in explosion-proof battery-powered heavy vehicles for coal mine
HU Peng
Abstract：In order to improve the overall performance of coal mine explosion-proof battery-powered heavy vehicles,a brand new design concept was adopted for explosion-proof low-voltage DC/AC frequency conversion technology on the controller,driving circuit and program control.The author also analyzed the working state of the inverter in explosion-proof 35 tons shovel plate bracket carrier,and effectively improved the cooling function of the inverter and the vehicle's loading capacity."Mining" traction system improved the vehicle's soft features of high torque at low speed,to realize the inverse proportion change of rotational speed and torque,improve vehicle traction,meanwhile,the motor output current and rated current were basically the same,the work efficiency reached 98％.
