Some Faults Judgment of Battery Electric Locomotive

The Device Voltage Of Battery Electric Locomotive Power Source Drops Sharply

1. Direct short circuit of positive and negative poles in power supply devices due to internal or external factors

2. In the battery electric locomotive pack, there are several "reverse poles" of the electric locomotive battery .

3. Poor contact between power cord and battery electric locomotive pole or pin connector

"Out of Control" of Pulse Speed Regulating Electric Locomotive

2. Out of control in the process of accelerating speed regulation: the sudden change of the electric locomotive from low speed to full speed

3. From full-speed to low-speed speed speed regulation to out-of-control: the performance of the electric locomotive can not decelerate. There are many reasons for "out of control". The main reason is that the components are damaged or the converter capacitors are not charged or insufficiently charged, and the thyristor (thyristor) is shut down continuously because of low voltage, which causes electric locomotive out of control (thyristor).
