摘 要:在大短路电流作用下,机械损伤的基本形式是变压器绕组变形,它们发展的典型方式是变形引起局部放电,匝、层间短路,整段主绝缘放电或完全击穿导致主绝缘破坏。因此,变压器出口短路后的检测试验一项必要的关系到运行安全的重要工作。

Abstract: In the large short circuit current, mechanical damage in basic form is transformer winding deformation, which development is deformation causing partial discharge, short circuit between turn and interlayer, the entire main insulation breakdown or completely destroyed of the main insulation. Therefore, Electrical test of transformer in outlet short circuit is a necessary work which relate to the safe operation. Keyword: transformer; outlet short circuit; electrical test
