摘要

通过对某型1 100 kV变压器套管（A型）的抗震计算

发现瓷件圆弧处的应力比瓷根部直线部分的应力大的现象。在另一种结构的1 100 kV变压器套管（B型）的抗震试验中

证实了计算中遇见的瓷件圆弧处的应力比直线部分应力大的现象

因此仅以瓷根处直线部分的应力作为抗震试验通过与否的标准并不准确

如何判断抗震试验是否通过还需进一步的探讨。

Abstract

By anti-seismic calculation of one type of 1 100 k V transformer bushing（Type A）

it reveals the arc area stress is bigger than it in straight line area

and this is verified in anti-seismic test of another type of 1 100 k V transformer bushing（Type B）. Therefore

it is not accurate to take root-section area stress to determine whether the seismic test is pass or not. It needs further discussion to how to judge the seismic test is pass or not.
