四、整流调压电路的工作特性如上所述,8K机车的牵引整流调压电路,是由一段全晶闸管控制桥和一段半控桥,再加电机磁场晶闸管无级削弱电路组成的(见图1)。每一转向架的两个电机串联就由这样的一组电路独立供电和控制,两节四轴机车共有四组这样的电路。除磁场削弱晶闸管臂为单独 Rectifier circuit work characteristics As mentioned above, 8K locomotive traction rectifier regulator circuit is a full SCR control bridge and a half-control bridge, coupled with the motor field thyristor stepless weakening circuit (see Figure 1 ). The two motors for each bogie are independently powered and controlled by such a set of circuits, with a total of four such sets of circuits on two four-axis locomotives. Throttling the thyristor arm apart from the field is separate
