摘要
穿墙套管是40.5 kV空气绝缘开关柜的核心元器件之一,其绝缘性能决定了开关柜的绝缘水平。文中通过对穿墙套管的多起典型事故原因进行深入分析研究,明确了套管在安装使用过程中的关键技术。针对套管在选型和安装使用过程中出现的典型事故原因,提出了相应的预防措施。
Wall bushing is one of the core components of 40.5 kV air-insulated switchgear,and its insulation perfor-mance determines the insulation level of the whole switchgear.In this paper,the key technologies of bushing installa-tion and use are clarified through in-depth analysis and research on the causes of many typical accidents of wall bush-ings.Corresponding preventive measures are proposed for the typical causes of accidents in the process of bushing se-lection and installation.
