旨在为超高压以上等级罐式避雷器的设计提供技术支持。

Abstract

The uniformity of shared-voltage on resistors of the 800 kV tank-type lightning arrester is of significance to safe operation of the arrester. In this paper

the potential distribution of 800 kV tank-type lightning arrester is analyzed via the software Ansys

and the influences of the parameters

such as the distance between two grading rings as well as the shell height and diameter of the grading ring

on the potential distribution and electric field intensity of the arrester are analyzed. This study may provide technical support for design of the tank-type lightning arrester of super-high voltage level.
