Test device for train power supply system of electric locomotive

Abstract

The invention discloses a test device for a train power supply system of an electric locomotive. The distribution boxes of the device are connected with the locomotive through locomotive power supply sockets and leads; the distribution boxes are connected with each other through leads and wiring terminals; the distribution boxes and load control cabinets are connected through leads and wiring terminals; the load control cabinets are arranged in the box type transformer; a resistance band is arranged in a load resistance cabinet; a centralized control experiment control box for detecting signal and fault of a centralized control device of an analogue locomotive is arranged between a locomotive centralized control socket and a locomotive portable lamp plug; a control circuit arranged in each distribution box and load control cabinet selects experiment load resistance according to an operation button of each distribution box and load control cabinet; and a main loop arranged in each distribution box and load control cabinet conducts test and state display in each distribution box and load control cabinet according to the experiment load resistance selected by the control circuit. According to the invention, the requirements of ground load experiment of a train power supply cabinet are met, and the test efficiency is improved; and moreover, the operation is simple and reliable, the manufacturing cost is relatively low, and the demands of existing experiment site are met.

Description

technical field [0001] The invention belongs to test equipment, in particular to a test device for an electric locomotive train power supply system. Background technique [0002] With the rapid development of the modernization of domestic railway technology and equipment, new electric locomotives must have the ability to convert passengers and freight, and at the same time alleviate the tense situation of 120km / h passenger transportation on the basis of satisfying railway freight. Therefore, the train power supply system of the locomotive should be capable of directly Capable of providing DC600V power supply. In order to meet the test requirements of the train power supply system for newly built locomotives, most of the train power supply systems are tested on DC600V test benches for direct power supply locomotives. The test bench is composed of software test bench, load control cabinet, load resistance cabinet, test machine room and other parts. The control part of the te...
