在东风型及东风_2型内燃机车上,辅助发电机向蓄电池充电回路,看起来并不十分复杂,但是一旦出现故障,要根据不同的故障现象,做到稳、准、快排除故障,并不是那么容易。辅助发电机充电回路常出现的故障,从表面上看不外乎两种,即辅助发电机电压过高或不发电。当然,充电回路的故障往往同电压调整器的故障有关。不过就辅助发电机本身而论,归纳起来实际常出现的故障多属于辅助发电机不发电或称蓄电池放电一种。而由电压调整器造成的控制部分或激磁部分故障,一种可能是使辅助发电机不发电,另一种可能是由三
In the Dongfeng and Dongfeng _2 diesel locomotive, the auxiliary generator to the battery charging circuit, does not seem very complicated, but in the event of failure, according to different symptoms, so stable, accurate and quick troubleshooting Not so easy. Auxiliary generator charging circuit failures often appear on the surface no more than two, that is, auxiliary generator voltage is too high or not generating electricity. Of course, the fault of the charging circuit is often related to the failure of the voltage regulator. However, in terms of auxiliary generators themselves, summed up the actual failures often belong to auxiliary generators do not generate electricity or a battery discharge. The voltage regulator caused by the control part or the excitation part of the fault, one may be to make the auxiliary generator does not generate electricity, the other may be three
