五、电传动装置及电气控制系统(一)概况东风4型内燃机车的将柴油机功率转变为驱动车轮的牵引力的传动装置是交-直流电传动装置,它的工作原理是牵引发电机——三相交流同步发电机在柴油机的驱动下发出三相交流电,经硅整流柜变成直流电,再输送给六台将电能转变成驱使车轮旋转的机械能的牵引电动机,牵引列车运行。牵引发电机是由一个交流同步励磁机发出的交流电,经励磁整流柜变为直流电后给其转子绕组励磁。为了使牵引发电机能充分利用柴
V. Electrical Transmission Device and Electrical Control System (I) Overview The transmission device of Dongfeng 4 diesel locomotive that converts the power of diesel engine into traction force for driving the wheel is AC-DC transmission device. Its working principle is traction generator-three-phase The AC synchronous generator, which is driven by a diesel engine, sends out three-phase alternating current, which is converted to direct current through a silicon rectifier cabinet and then sent to six traction motors that convert electric energy into mechanical energy that drives the wheels to rotate, and trains the train to run. Traction generator is an AC synchronous excitation machine issued by the exchange of electricity, after the excitation rectifier into a direct current to the rotor winding excitation. In order to make the traction generator can make full use of wood
