摘　　要：三菱500 kV HGIS设备在长期运行过程中,由于长期在户外受到自然环境中雨水的侵蚀和风化等,导致出现刀闸地刀轴封处漏气、分合不到位等情况,因此操作隔离开关时经常出现卡阻或操作失效的故障。如果不及时预防设备的隐患,就会逐步发展甚至量变发展为质变,从而发生设备事故,对人生安全、电网和设备安全造成极大的威胁。研制防雨罩进行防雨防晒,避免轴封处渗漏水导致锈蚀漏气、分合时卡滞等缺陷。During long-term operation,Mitsubishi 500 kV HGIS equipment often experiences malfunctions such as jamming or operational failure when operating isolation switches due to factors such as outdoor exposure to natural rainwater erosion and weathering,as well as air leakage and inadequate opening and closing at the switch shaft seal.If the hidden dangers of equipment are not prevented in a timely manner,they will gradually develop,even from quantitative to qualitative changes,leading to equipment accidents and posing a great threat to human safety,power grid and equipment safety.This project aims to develop a rain cover for rain and sun protection,avoiding defects such as rust,air leakage,and jamming during opening and closing caused by water leakage at the shaft seal.
