摘要
提出了异步电机的一种新的"Г"形等值电路。利用星角变换法展示了推导过程。分析表明,新"Г"形等值电路比旧"Г"形等值电路降低了计算误差,从而能提高工程计算精度。
A new kind of Г-shape equivalent circuit of asynchronous machine is proposed.With the help of Y-△ transformation method,the derivation process is demonstrated. The analysis shows that the newГ-shape equivalent circuit has reduced the computation error compared with the old one. Therefore,the accuracy of engineering computation is improved.
