在行车途中,节压器部分出现一时不能立即修复的故障时,通常都爱釆用把直流发电机的磁场和电枢接线柱直接用导线联起来的办法使发电机继续发电。但这样做,发电机的输出电压就失去了控制。结果,其输出电压随着转速的增高而增加,甚至有可能大大超过车上用电设备的最大允许电压,从而严重影响发电机,蓄电池和其它用电设备的使用寿命。故这种 On the way of traveling, the section of the economizer may not be able to be repaired immediately, and usually the generator is to be continued to generate electricity by directly connecting the DC field and the armature terminal with wires. But doing so, the generator’s output voltage loses control. As a result, the output voltage increases with increasing speed and may even exceed the maximum allowable voltage of on-board electrical equipment, seriously affecting the service life of generators, accumulators and other electrical equipment. So this
