Abstract: The double-machine traction speed-raising switch used on Lanzhou-Xinjiang conventional speed line is not in place in the switch conversion process for many times, and the switch is normal after replacing the relay (1DQJ). Through the test and analysis of the combination fault replacement relay of the speed-raising switch, this paper puts forward a solution to the problem, which has been implemented in the field and achieved good results.

Key words: 1DQJ, contact corrosion, stop circuit, solution
