Failure analysis of microcomputer control system for SS4 0038 locomotive

简要介绍了国内第一台采用微机控制的电力机车ＳＳ４－００３８号在宝成线上的运行情况，对微机控制系统的可靠性作了一些探讨，并分析了该ＳＳ４００３８号机车最初十万公里运行期间控制系统发生较多的故障，最后对微机控制系统在电力机车上的广泛应用提出了一些改进意见．

It is brtefly depicted the running performance of the first microcomputer control eleCtriclocomotive in China,SS4 0038,on Baoji-Chengdu line. The reliability of microcomputer control syStem isexplored. Control system failures are analySed which occur mostly during the initial 100 000 km running ofthis locomotive. bedsides,some advices for further application of microcomputer control system to locomotiveare put forward.
