HXD1D型机车主变压器故障防治

Fault Prevention of Main Transformer of HXD1D Locomotive

HXD1D型机车主变压器为机车本身和牵引车辆提供转换后的电能,在机车上占据非常重要的作用,其包含很多附属保护装置,如油流继电器、温度传感器、压力释放阀、布赫继电器等,这些传感器起到保护主变压器始终处于正常工作状态的作用。在机车实际运用中,该段发生了很多非主变压器本身故障,而附属保护装置起保护引发的机破,影响了机车的正常运行。该文就如何防治主变压器附属保护装置动作进行了研究。

HXD1D locomotive main transformer provides converted electric energy for the locomotive itself and traction vehicles,and plays a very important role in the locomotive.It contains many auxiliary protection devices,such as oil flow relay,temperature sensor,pressure release valve,Bucher relay,etc.These sensors protect the main transformer from always working normally.In the actual application of the locomotive,many non main transformer faults have occurred in this section,and the auxiliary protection device has Locomotive Failure caused by protection,which affects the normal operation of the locomotive.This paper studies how to prevent the action of auxiliary protection device of main transformer.
