异步电机新'Г'形等值电路

摘要

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 new Г-shape equivalent circuit has reduced the computation error compared with the old one. Therefore, the accuracy of engineering computation is improved.%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.
