脉冲电压法测直流电机匝间短路的分析
|
摘要
本文针对直流电机绕组匝间短路的问题,研究了脉冲电压法测试电机匝间短路的情况,进行了电路设计,理论分析,仿真模拟,数据分析。脉冲电压法是交流电经整流后对电容充电,然后电容对电气元件放电,RLC电路发生振荡,通过研究振荡波形的峰值、周期、消散时间来判断元件短路情况。研究发现振荡波形频率越高、周期越小、系统消散越快,元件短路匝数越多。该方法方便、快捷、高效。
In this paper, the short-circuit between turns of dc motor winding is studied, and the circuit design, theoretical analysis, simulation and data analysis are carried out. Impulse voltage method is capacitor charging after rectification of AC, capacitor then discharge electric elements, and the RLC circuit will oscillate. through the study of peak value, period and dissipation time of the oscillation waveform, the short-circuit time of the component is judged. The study found that the higher the frequency of the oscillation wave, the smaller the period, the faster the system dissipated, the more the component short-circuit turns. The method is convenient, fast and efficient.
