摘要

根据用于海拔2 500 m地区的2 400 kV直流电压发生器顶端均压罩和均压环的结构

有针对性地给出了电场强度控制值

使用有限元软件COMSOL对2 400 kV直流电压发生器的电场进行仿真和校验

发现顶端均压罩的最大场强是8.12 kV/cm

均压环的最大表面场强是9.58 kV/cm。为提高2 400 kV直流电压发生器的绝缘性能

有必要对均压环进行结构优化

在多次尝试后

增加了表面场强较大的几个均压环的曲率半径

并调整了均压环的位置。经过优化后

均压环的最大表面场强降低至8.12 kV/cm

降低约15.2%

提高了2 400 kV直流电压发生器的绝缘性能。

Abstract

According to the structures of both grading shield and grading ring on top of 2 400 k V DC voltage generator for the areas at altitude of 2 500 m

the control value of electric field intensity is specifically given. The finite element software COMSOL is used to simulate and calibrate the electric field of 2 400 k V DC voltage generator

finding that the maximum electric field intensity of the grading shield on the top is8.12 kV/cm

and the maximum surface electric field intensity of the grading ring is 9.58 kV/cm. In order to improve the insulation performance of the 2 400 kV DC voltage generator

it is necessary to optimize the structure of the grading ring. After many attempts

the curvature radius of several grading rings with large surface electric field intensity is increased and positions of grading rings are adjusted. After optimization

the maximum surface electric field intensity of the grading ring is reduced to 8.12 kV/cm

a reduction of about 15.2%

and the insulation performance of the 2 400 kV DC voltage generator has been improved.
