摘要
以留古220 kV变电站主变压器低压绕组损坏为例,介绍各种接线方式下变压器低压侧短路电流状况,分析控制变压器低压绕组短路电流措施的适应性及可行性,指出河北省南部电网在今后的变电站设计中应予以关注的问题。
This paper analyzes the low-voltage short-circuit current of transformer under various conditions,taking of low-voltage winding burned of Liugu 220 kV main transformer as an example,brings forward the control measures of transformer low-voltage winding short-circuit current,and points out that the matters should be paid attention to in the future substation design in Hebei Southern Grid.
