Train power supply control system test device and method thereof

Abstract

The invention discloses a train power supply control system test device and a method thereof. The train power supply control system test device comprises a test machine case, a control computer, and an alternating current (AC) power source or a direct current (DC) power source. An external alternating current power source provides power for the test machine case through the AC power source or the DC power source. The test machine case is connected with the control computer. The test machine case collects output signals of an external train power supply control system and transmits data to the control computer to calculate and display. According to the work state of the current train power supply control system and test requirements, the control computer operates a test model of the train power supply control system in real time, sends operation instructions to the test machine case, and outputs corresponding test signals to the train power supply control system. According to the train power supply control system test device and the method thereof, test project is complete, compatibility is good, test is fast and convenient to conduct, regular inspection and test to the train power supply control system can be achieved, and operation reliability of the train power supply control system is improved.

Description

technical field [0001] The invention relates to a power supply control system testing device and a method thereof, in particular to a power supply control system testing device and a method applied to railway train vehicles. Background technique [0002] The train power supply cabinet is a converter device on passenger electric locomotives. It can rectify rated single-phase AC 860V into DC 600V output, and provide working power for air conditioners, ventilators, lighting and other equipment of passenger trains. At present, in order to promote energy saving and consumption reduction of railways and improve transportation efficiency, the Ministry of Railways of my country has canceled power generation cars on a large scale and promoted DC600V train power supply cabinets for electric locomotives. Electric locomotive train power supply cabinets have been used on a large scale on electric locomotives including AC and DC electric locomotives (SS7C / SS7D / SS7E / SS8 / SS9 / SS9G, etc.) and...

AI Technical Summary

Problems solved by technology

[0007] (1) The test items of the existing train power supply control system are not complete enough, especially the protection function and logic function test cannot be realized;

[0008] (2) The cost of the load test bench of the train power supply cabinet in the prior art is relatively high, the price of a single unit is basically around 700,000-1 million, and each locomotive depot can basically only be e
