摘　　要：针对组合电器盆式绝缘子漏气故障,从现场检查和试验检测两方面对盆式绝缘子漏气原因进行分析,认为盆式绝缘子安装孔积水,冬季孔内积水结冰膨胀,导致绝缘子运行过程中出现裂纹是造成盆式绝缘子漏气的主要原因,并提出防范措施和建议。Combined with electrical insulator leakage fault ba-sin,the paper analyzes the cause of the leak form through theon-site inspection and test for detection, and considers thatwater basin insulator mounting holes, bore water freezes inwinter swell, causing the process appears to run against theinsulator crack is the main cause basin insulator leakage, andproposes preventive measures and proposals.
