摘要
Y/y联结绕组和Y/△联结绕组安装于同一三相心式铁心上的整流变压器具有特殊的三次谐波磁场分布,Y/y联结绕组产生的较大的三次谐波漏磁通使穿过它的线圈导体产生严重的涡流损耗是绕组最上部4匝线圈导体绝缘损坏的原因,同时同一位置的一次绕组存在过热的可能性。
When the Y/y linked coiling and the Y/△ linked coiling were installed on the same three-phase heart type iron in large rectifier transformer,the distribution of the third harmonics of leakage magnetic was special.The bigger third harmonics of leakage magnetic made by the Y/y linked coiling of the rectifier transformer make serious eddy current loss in the conductor of coiling under leakage magnet and make the isolation of four circle conductors at the topmost department of the Y/y linked coiling damaged,and the primary Y coiling at the same position is likely to be hot.
