40.5 kV大电流固封极柱绝缘结构电场分析及优化设计

Gaoya dianqi, 2019
大电流固封极柱必须大量采用软连接,容易造成局放超标及沿面放电,因而对其进行绝缘结构分析及优化设计件具有重要意义。文中运用有限元分析方法得出了40.5 kV大电流固封极柱的电场分布云图,并提取分布较为集中的软连接及固定螺栓周围气体域的电场分布,指出软连接附近SF6气体中电场畸变,造成局放过大及沿面放电。依据复合绝缘电场理论,提出了在软连接周边固封极柱腔体内浇筑屏蔽网,并使屏蔽网与软连接等电位的优化方法。通过电场分析,优化后的软连接固定螺栓附近SF6气体电场强度由12 kV/mm降低为7.5 kV/mm ...
