目前ND_5型机车“恒功率励磁调节”和“警哨粘着控制”两电子系统故障率高,危及行车安全正点,针对上述惯性故障,本文介绍ND_5型机车电子系统的故障走车电路.经加装技改后的机车在运行途中发生电子故障,出现降功电流小等情况,乘务员在司机室内能很方便地实施三种故障工况转换,维持机车运行返段.该项技改实施简便,费用极少,使常见电子故障应急处理程序化,安全可靠,是减少机破、临修的有效措施.
At present, the failure rates of two electronic systems of ND_5 locomotive “constant power excitation regulation” and “police whistle sticking control” are high, endangering the punctuality of traffic safety. In view of the above inertia failure, this article introduces the faulty driving circuit of ND_5 locomotive electronic system. After the technical transformation of the locomotive in the operation of the way electronic fault occurs, the emergence of small work current and other small cases, the flight attendant in the driver’s room can be easily implemented three fault conditions to maintain the locomotive to run back section of the technical implementation of simple, cost Very few, so that common electronic failure emergency procedures, safe and reliable, is to reduce the machine broken, temporary repair effective measures.
