Abstract

The embodiment of the invention discloses a train power supply load test device. The device comprises a first power connector, a second power connector, a first main contactor, a second main contactor, a rectifying circuit, a switch module, at least two first load modules, a first switch, a second switch, a pulsating voltage detection module and a controller, wherein the first switch and the second switch correspond to the first load modules. Whether a direct-current power supply and an alternating-current power supply are connected to a first load or not is determined by controlling the firstmain contactor, the second main contactor, the first switch and the second switch to be switched on or off through the controller to realize load detection testing. Therefore, a problem that no passenger locomotive train power supply system load test equipment compatible with two power supply systems exists in an existing locomotive depot is solved, and the effect that the load test requirementsof trains compatible with two power supply systems of an internal combustion locomotive and an electric locomotive can be met is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of locomotive power supply, in particular to a load test device for train power supply. Background technique [0002] Electric locomotives and diesel locomotives mainly engaged in passenger transport are equipped with train power supply devices to meet the electricity needs of air conditioning, heating, lighting, furnaces and other electrical appliances in passenger cars. The quality of the power supply system of passenger locomotives is closely related to the travel life of passengers. Therefore, after the major, medium and minor repairs of passenger locomotives, the train power supply system must be tested and inspected, and even the train power supply system of the back-haul locomotives should be tested and inspected before they leave the warehouse and go online, especially the train power supply of passenger locomotives. System load test. [0003] However, at present, many locomoti...
