摘要：运行中的全封闭气体绝缘高压设备组合电器（GIS），由于内部导电杆电流磁场的电磁感应，在GIS外壳产生环流和涡流，会产生功率损耗，使得GIS外壳或其他零部件发热，本文应用电磁式电流互感器原理及其误差公式分析了GIS外壳环流的机理及现象，且应用互感器原理粗略计算了环流及其损耗，本方法机理简洁清晰，可用于计算感应电流及其损耗。计算表明GIS设备外壳分段绝缘是一种很好的解决方法。

Abstract：the circulating current and eddy current，induced by electromagnet in the AC on the conductor pole fixed in the enclosure GIS，can generate some power loss.and heat on the medal shell and other components，By the principle of electro-magnetic current transformer and error calculation equation，we analyzed the physical phenomenon of the circulating current in the enclosure of GIS，and simply calculated the circulating current and its power loss in the enclosure.Meanwhile，we discussed the influences of circulating current and its power loss on the operation of GIS and earth wire.The computaion shows that sectional insulation shell is a good sulation.
Key words：GIS；medal shell；circulating current；power loss；sectional insulation
