摘　　要：采用有限元法软件分别计算了126kV SF6套管在有无接地内屏蔽时瓷套内部和外部的场强分布和电位分布。分析了接地内屏蔽的位置和尺寸与电场分布的影响,并对接地内屏蔽的结构进行了优化设计,为126kV SF6套管接地内屏蔽的设计提供了理论依据。Based on finite element method, the interior and exterior electric field strength and potential distribution of 126 kV SF6 bushing, without grounding inner shield and with grounding inner shield, was analyzed. The relationship between the position, the size of the grounding inner shield and electric field distribution was analyzed also. The structure of the grounding inner shield was optimized for supplying theoretical references to design the grounding inner shield of 126 kV SF6.
