The invention provides detection equipment for a low-voltage cabinet of an electric locomotive, and the equipment comprises a first signal transmission device which outputs a plurality of target to-be-detected signals corresponding to the to-be-detected low-voltage cabinet of the electric locomotive to the to-be-detected low-voltage cabinet of the electric locomotive from N preset to-be-detected signals according to the model of the to-be-detected low-voltage cabinet of the electric locomotive, the N preset to-be-tested signals comprise various to-be-tested signals of the to-be-tested electric locomotive low-voltage cabinet of different models, and the second signal transmission device receives a plurality of target feedback signals which are output by the to-be-tested electric locomotive low-voltage cabinet and correspond to the target to-be-tested signals respectively and outputs the target feedback signals to the processing device, and the processing device processes each target feedback signal to obtain a detection result of the target signal to be detected and outputs the detection result to the result output device, and the result output device outputs the detection result. Therefore, the electric locomotive low-voltage cabinet detection device can flexibly detect the electric locomotive low-voltage cabinets of various models.
Description
technical field [0001] The present application relates to the technical field of electric locomotive detection, and in particular, to a detection device for a low-voltage cabinet of an electric locomotive. Background technique [0002] There are many electrical components in the low-voltage cabinet of the DC electric locomotive, and the lines are complex. Before installing it on the locomotive, the low-voltage cabinet needs to be tested to ensure that the control lines and electrical components in the low-voltage cabinet after loading are in normal operation and improve the overall performance. The detection efficiency of the car can be avoided, and the second repair can be avoided. [0003] At present, when testing the low-voltage cabinet of a DC electric locomotive, it is necessary to use the low-voltage cabinet testing equipment corresponding to the locomotive model. Test equipment to test. Therefore, the detection flexibility of the low-voltage cabinet of the electric ...
