摘要
通过对从采用新换位方式的试验线棒上获得的数据的再分析,指出了发电机定子线棒中股线间温差主要是由发电机转子励磁磁通引起,新换位方式固然能消除线棒中股线温升过高现象,但并没有削弱端部漏磁通,要降低端部漏磁通可以通过改善发电机端部结构进行。
By re-analyzing the data acquired from tested bars that new transposition pattern is adopted, puts forward the temperature difference between bar strands is caused by generator rotor excitation flux. Even though the new transposition pattern is able to reduce the excessive temperature rise,it cannot re- duce the end magnetic leakage unless the generator end structure is changed.
