Abstract
The insulator is an important part of the HVDC converter valve,and the electric field analysis of the converter valve is very important for the design of the HVDC converter valve.In this paper,the surface electric field distribution of the converter valve shield system considering the post insulators.In order to improve the calculation efficiency,the integral equation field domain dement and boundary element coupling method is proposed.The integral equation field domain element method is introduced into boundary element method (BEM) to deal with the calculation.The method is proved to be correct through the comparison with 2D finite element method result.The post insulator models in different situation is built,by use of coupling method,the surface electric field intensity of shielding system and the electric field in the insulator are analyzed,and the range of application of boundary element method is broaden.关键词
