Nowadays, battery electric locomotives are widely used in branch roadways, small-scale mine transportation or shunting in medium-sized mines. Because of long-term application in industry and mining, heavy load and rugged road, traction power has become the primary consideration in the design of battery electric locomotive. Generally, AC traction and DC traction are used in electric locomotives, but now AC traction power occupies the market more. Why is AC traction the main power system of battery electric locomotives? Let's have a look.
The climbing ability is stronger:
The climbing ability of ordinary DC battery electric locomotive is 11 and that of locomotive with AC variable frequency speed control system is 60. Under the same sticking condition, the traction rearrangement of AC traction variable frequency speed regulating vehicle can operate on the slope of the line that the DC vehicle can not go to.
Speed regulation performance is better:
Stepless uniform speed regulation, high precision, the lowest adjustable frequency 1HZ, the lowest adjustable speed 0.5r/min.
The speed can be preset. Once a certain speed is set, even downhill driving will not exceed the set value. It can avoid accidents caused by speeding and is safe and reliable. The increase in frequency takes 5 seconds, and even if the driver suddenly accelerates, the locomotive still increases to its maximum in 5 seconds.
