均压环结构对800kV罐式避雷器电位分布影响分析
|
摘要
800kV罐式避雷器电阻片电压分担的均匀性对避雷器的可靠运行意义重大。文中通过Ansys软件分析800kV罐式避雷器的电位分布,通过调整均压环两环间距、均压罩高度、均压罩直径等尺寸,分析各尺寸变化对800kV罐式避雷器电位分布及电场强度的影响规律,旨在为超高压以上等级罐式避雷器的设计提供技术支持。
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.
