摘要
本文通过对±2400 kV/200 mA特高压直流试验电源不同种类屏蔽罩不同区域的电场进行分析,得到电场强度最大值及其位置,为绝缘结构优化设计提供依据。利用Ansoft软件分别对设备均压环区域进行电场的二维有限元分析,论证了整体式均压环在有限空间内具有设计尺寸小的优势。本文的仿真分析结果可为后续特高压直流电源试验设备的优化设计提供参考。
The electric field in different regions of various types of shielding enclosures for a±2400 kV/200 mA ultra high voltage direct current test equipment is analyzed to obtain the maximum electric field value and its location and provide evidence for the optimized design of insulation structures.Ansoft software is used to conduct a two-dimensional finite element analysis of the electric field in the equipment’s grading ring area.The advantage of an integral grading ring in having smaller design dimensions in indoor environments with limited space is demonstrated.The simulation analysis results presented in this article provide reference for subsequent optimized designs of ultra high voltage direct current test equipment.
