摘要

为检测GIS内局部放电特高频信号

需在盆式绝缘子金属法兰开孔处设置局部放电传感器

而金属法兰开孔会对盆式绝缘子表面及开孔处电场强度产生一定影响。笔者应用有限元分析软件ANSYS对三相分箱式252 kV GIS中盆式绝缘子电场强度进行了仿真计算

研究金属法兰开孔尺寸大小和结构对盆式绝缘子表面和浇注孔表面电场强度的影响。仿真结果表明

浇注孔结构对盆式绝缘子表面电场强度影响显著

金属法兰开孔大小对盆式绝缘子表面电场强度影响较小

经过优化后的小尺寸浇注孔绝缘子表面电场强度最大值比无浇注孔时高出3.21%

达到了预期目标。

Abstract

In order to detect the UHF signal of GIS inner partial discharge

it’s necessary to install partial discharge sensor on the metal flange pouring hole of basin-type insulator

which will produce influences on the electric field of basin-type insulator surface.To study the effect of the dimension and structure of pouring hole of metal flange to the electric field of basin-type insulator surface

ANSYS is adopted to calculate the electric field of basin-type insulator of 252 kV three phase in three tank type GIS.The simulation results show that the structure of pouring hole has a significant effect on the electric field of basin-type insulator surface.The dimension of pouing hole of metal flange has few influence on the electric field of basin-type insulator surface.Compared with no pouring hole

the maximum electric field of basin-type insulator surface increases by 3.21%

which achieved the anticipated target.
