辅助机组的正常工作对于保证主电路功率的发挥及各种性能的实现有着重大的作用,而辅助机组的正常工作又是由控制电路协调实现的。图1是8G型电力机车辅助电路简图,它没有专职的劈相机,而是将压缩机电机或两台通风机电机之一兼作劈相机,利用C_(117)、C_(118)电容分相起动后供给其它辅助电机三相交流电。
The normal work of the auxiliary unit plays an important role in ensuring the power of the main circuit and the realization of various performances, and the normal work of the auxiliary unit is coordinated by the control circuit. Figure 1 is a schematic diagram of an auxiliary circuit of an 8G electric locomotive. It does not have a full-time split-phase camera. Instead, one of the compressor motor or one of the two ventilator motors is also used as a split-phase camera. The phase splitter uses the C_ (117) and the C_ (118) After the start of other auxiliary motors to supply three-phase AC.
