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。

Abstract

Wall bushing is one of the core components of 40.5 kV air-insulated switchgear

and its insulation performance determines the insulation level of the whole switchgear.In this paper

the key technologies of bushing installation and use are clarified through in-depth analysis and research on the causes of many typical accidents of wall bushings.Corresponding preventive measures are proposed for the typical causes of accidents in the process of bushing selection and installation.
