Two Specific Implementation Mode Of Stringing Mining Electric Locomotive

The utility model relates to a stringing type industrial and mining electric locomotive with an independent control power supply device. It solves the problems that the DC-DC converter brought by the control power supply device of the existing stringing type industrial and mining electric locomotive is easy to be damaged, the failure rate is high, and the locomotive control failure and danger are caused by the instability or lack of control signal.

The control power supply device of the stringing type industrial and mining electric locomotive includes a 24V DC generator and a lead-acid battery. The 24V DC generator is connected with the air compressor pulley through a belt, and the lead-acid battery is connected with the 24V DC generator.

Compared with the traditional trolley type electric locomotive with DC traction motor, it has the characteristics of high efficiency, large output torque and smooth speed regulation. The adopted AC traction motor armature wireless coil, no commutator, no carbon brush, simple manufacturing process, strong and durable, low cost, high driving efficiency, low torque ripple, low noise, no position sensor, high speed limit, good moisture-proof performance, reliable operation, obvious advantages.

In addition, the main body of the frequency converter is set in the vehicle body, and the controller of the frequency converter is set in the cab, which can increase the space in the cab, and facilitate the operation, maintenance and commissioning of the driver and maintenance personnel.
