摘要
在一起冶金企业变电站倒闸操作中，由于对变压器低压侧反充电产生励磁涌流，造成相邻负荷的误跳闸事故，文章分析了励磁涌流产生的机理、影响因素、特征及其对电网负荷的影响，并对稳定措施进行了初步探讨。
In the transfer switching operation of a substation in a metallurgical plant, the excitation inrush current occurred to cause the wrong trip of adjacent equipment due to the charging at the low voltage side of the transformer. The mechanism, factors, features and influence of excitation inrush current on the power network load are analyzed, and the measures to stabilize the operation are briefly discussed.
