脉流牵引电动机变压器电势测量方法的研究

Research on Measure Method of Transformer Potential in Pulsating Current Tronction Motor

本文提出了一种用50HZ交流代替100HZ交流来测量变压器电势的新方法。对不同频率时的激磁电流与电枢电流,磁通与变压器电势间的相位差和数值进行了理论计算。实验结果表明,用这种方法测量变压器电势是简便的。

In the paper, a novel method in which the 100HZ AC is replaced with 50HZ AC to measaue the transformer potential of the motor is presented. The phase differences between excitation current and armature current, magentic flux and transformer potential and the amplitudes of all these variales have all been calculated at the two frequencies. The test result shows that the method is simple and convenient to measure the transformer potential.
