一、加装目的监视牵引电动机三个支路的电流分配情况,从而能及时地查找出电流分配不均的原因,予以排除,以保证204电机的正常工作条件。二、加装方法我段所采用的改装方法,可使分路电流表既能显示牵引工况的电机电流,亦能显示电阻制动工况的电机电流。按东风机车电路的原设计,电阻制动工况流过牵引电动机电枢的电流
First, the installation purpose To monitor the current distribution of the three branches of the traction motor, which can find out the current cause of uneven distribution in time to be excluded in order to ensure the normal working conditions 204 motor. Second, the installation method I paragraph modified method used, can shunt ammeter can show both traction motor current conditions, can also display the resistance braking conditions of the motor current. According to the original design of Dongfeng locomotive circuit, the current flowing through the armature of the traction motor through the resistance braking condition
