Description

Technical Field

[0001] This utility model relates to the technical field of EMU lighting systems, specifically to a power supply testing device for EMU headlights. Background Technology

[0002] When the power supply of the headlight assembly of a high-speed train fails, it will cause the high and low beam headlights and signal lights of the train to dim or not light up, which will seriously affect the safe operation of the train.

[0003] The existing headlight power supply of high-speed trains mainly consists of multiple individual power modules, and the power supply method of the combined power supply is basically the same. They all step down the 110V DC power supplied by the train to the voltage required by the lights, and supply power to the high and low beams and signal lights on the left and right sides of the train. Each individual power module does not affect each other and can work independently. When one power module fails, it can be replaced individually for small module repair, which has a very high repairability.

[0004] However, when the headlight power supply of a high-speed train fails, it is impossible to directly identify the specific faulty power module. The current practice still requires replacing the entire headlight power supply of the high-speed train and then removing and testing each power module individually to identify the faulty module. This involves a large amount of maintenance work, and the overall disassembly can also easily damage other normal modules.

[0005] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content
