摘要

为提高220kV电容套管的电气性能

在保持产品原有的绝缘裕度和高可靠性前提下

从改善心子主绝缘的利用效率着手

通过调整心子的径向和轴向场强分布

减小场强分布的不均匀程度

提高产品的起始局放水平。

Abstract

On the condition that the insulation margin and the high relability remain the same as the original product

starting from improving the utilization factor of the dominant insulation of the core

by adjusting the electric field strength distribution in radial and axial direction to lower the non-uniformity of electric field strength

the initial partial discharge level is raised

hence the electric performance of220kV capacitive bushing is improved.
