Description

Technical field

[0001] The invention relates to a device and method for testing track circuit compensation capacitors in UM71, ZPW series and sections with track circuit compensation capacitor standard equipment for railway electric affairs departments. Background technique

[0002] At present, the railway has entered a period of leaping development. In order to open high-speed trains, railway signal technology has continued to develop. Based on the introduction of French UM71 non-insulated track circuit technology, the ZPW automatic block track circuit system has been developed again in combination with national conditions. The Ministry of Railways has designated ZPW and UM71 as the block system for the development of the whole road in the future, providing technical support for "the main body of the locomotive signal". With a large number of UM71 and ZPW equipment being put into use on the track, there is no test method for the failure of the track circuit compensation capacito...
