摘要

通过对氧化铝陶瓷中气泡引起局部电场畸变导致绝缘故障进行了研究

建立了存在气泡缺陷氧化铝陶瓷绝缘子静态电场计算的三维数学模型;比较了有无气泡缺陷时氧化铝陶瓷绝缘子的电场强度;重点分析了气泡存在不同电场强度区域和距离下表面不同距离时对电场强度的影响

从而得到气泡缺陷对电场的影响规律。

Abstract

This paper summarizes some problems in Al2O3 insulator operation

and carries out the research on the insulation failure caused by local electric field distortion induced by the bubble in Al2O3 insulator. The three-dimensional mathematical model of electric field calculation of Al2O3 insulator with bubble defect has been established. The electric fields of the insulator with or without bubble defects are compared. It mainly analyzes the influence of bubble on electric field when it is in different electric field region and different distance. And it obtains the law of the influence of bubble on electric field distribution.
