Abstract

The invention provides a train power supply system for a diesel locomotive. The train power supply system comprises a power source conversion device and a microcomputer control device. The power source conversion device is the core of the whole power supply system, the microcomputer control device guarantees safety and reliability in operation of the power source conversion device, and a source ofenergy provided by the diesel locomotive is acquired through a diesel engine, so that adoption of the power grid for power supply is avoided. Aiming at thyristor three-phase rectification adopted forvariable frequency and variable voltage outputted by a synchronous traction generator of the diesel locomotive adopt, the train power supply system is additionally mounted on the diesel locomotive torealize DC600V stable output. Once the power grid on a line has faults or an electric locomotive fails in operation, the diesel locomotive with the direct power supply system can be put into operation to guarantee normal operation of railway transportation.

Description

technical field [0001] The invention belongs to the field of locomotive power supply, in particular to a train power supply system for diesel locomotives. Background technique [0002] The current 25G and 25T passenger trains all need DC600V DC power supply, and adopt the power supply mode of "centralized power supply for electric locomotives and decentralized conversion for passenger cars". The electric locomotive train power supply system rectifies the grid voltage, and the output DC600V power supply is supplied to passenger trains, and then the inverter power supply under the passenger train converts the input DC600V direct current into three-phase AC380V, 50HZ alternating current for air conditioning units and other loads, charging power supply The input DC600V direct current is converted into a DC120V power supply for battery charging, interior lighting and other loads, which can ensure the safe and comfortable ride of passengers. [0003] Diesel locomotive, as one of ...
