Battery locomotive resistance speed regulation is one of the locomotive speed control mode, which mainly adjusts the speed of the locomotive by changing the size of the resistor to change the current, and there are vulnerable parts in the resistance speed regulation, then the electric locomotive. What are the drawbacks of resistance speed regulation?
(1) The speed regulation performance is poor, the maximum speed cannot be set, and the climbing ability is insufficient. In actual operation, the speed cannot be set,
The track is ramped up, causing the locomotive to overspeed, which is prone to casualties and equipment accidents, and brings a threat to safety production;
(2) With resistance start and speed regulation, high energy consumption, long main transportation line in the well, in order to ensure the turnover rate of the mine locomotive, each locomotive runs for a long time, and also causes great waste in electricity consumption;
(3) The mechanical and controller are easily damaged and the maintenance workload is large;
(4) The traction force is small, the climbing ability is insufficient, and the motor has a short service life.
