摘要
机车启动和运行过程中经常发生牵引封锁故障,若不能及时排除就会影响机车行车安全。发生封锁牵引的因素较多,要按故障现象作出准确判断。对牵引封锁常见故障进行了分析,并给出排除故障的方法,确保了机车性能和行车安全。
Traction blockage usually occurs when the locomotive starts off or in the course of running. If the failure was not removed in time, it would have influence on the running security of the locomotive. There are lots of reasons for traction blockage, so correct judgment should be made according to different phenomena. This article makes a theoretical analysis on the failures frequently resulted from traction blockage and puts forward ways of troubleshooting to ensure the running performance and security of the locomotive.
