Power Supply Device for Trolley Locomotive

The control power supply device for trolley electric locomotive is a kind of overhead industrial and undergtround mining electric locomotive with independent control power supply device. The specific independent control power supply device saves narrow gauge locomotive the function of manual power supply, improves the performance configuration of overhead electric locomotive, and reduces the battery. The probability of frequency conversion also increases the service life of locomotives. We have the following specific understanding:

At present, the control power supply of railway transportation overhead electric locomotive in underground mine, metallurgy and other industries in China is all supplied by 24V system. The power supply used is provided by DC converter. The control power supply is directly introduced from the power grid to high voltage DC, and then converted to 24V DC by DC converter. Use of locomotive control system. Because of the poor quality of power supply in the overhead network of coal mine and metallurgical industry, the impact of power grid  narrow gauge locomotive and the large voltage difference between the head and the end of the network, the introduction of HVDC voltage has many AC impurities and sudden changes in voltage, which lead to the very easy damage of DC-DC converter and the high failure rate, narrow gauge locomotive which make the lighting and other electrical equipment unable to work normally and control it. Failure or absence of No. 1 causes locomotive control failure and danger.

The overhead industrial and mining electric locomotive with independent control power supply device, including air compressor, also includes 24V DC generator and lead-acid battery fixed on the electric locomotive. The 24V DC generator is connected with the belt pulley of the compressor through a belt, and the lead-acid battery is connected with 24V DC. The output terminal of the generator is connected. When in use, the original power is provided by the air compressor on the industrial and mining electric locomotive, and the 24V DC generator is driven by belt to generate electricity. The electricity generated is stored in the storage battery, and then the power required by the control signal is supplied to the outside through the storage battery.
