1) triple-harmonic field
三次谐波磁场
2) second harmonic magnetic field
偶次谐波磁场
3) High harmonic waves of magnetic field
磁场的高次谐波
4) the third harmonics of leakage magnet
三次谐波漏磁通
1.
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.
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。
5) third-harmonic flux
三次谐波磁通
1.
A new method for reducing core loss and excitation current in transfor- mers that utilizes the fundamental principles of third-harmonic flux modulation is proposed in this paper.
文中认为当在变压器基波磁通中加入某一幅值的三次谐波磁通后,能显著地降低铁耗和励磁电流。
