探析船舶电气设备铁损及其如何抑制

带有线圈的铁心在线圈接通正弦交流电流时会被反复磁化,因为磁滞现象会出现磁滞损失。加之铁心内部由于磁感应的作用,会出现涡流,涡流会在铁心内部流动,就会出现功率的损耗,也就是涡流损失。我们要谈及的铁损就是磁滞损失和涡流损失的综合。我们在此对铁损进行研究,就具有重要的现实意义。

@@@@With the core of coil in the coil through sinusoidal alternating current wil be magnetized repeatedly, because of the hysteresis phenomenon wil appear hysteresis losses. Internal due to magnetic induction effect, combined with core eddy current and eddy current in iron core internal flow, there wil be loss of power of eddy current losses. We want to talk about the iron loss is integrated magnetic hysteresis loss and eddy current loss. We are in the study of iron losses, and has important practical significance.
