摘　　要：有机合成绝缘子以其重量轻、抗污能力强、憎水性能优越等特征 ,在电网防污闪方面发挥了积极的作用 ,被广泛应用于重污秽及高山、边远等地区。青海电网自 1 992年首次挂网合成绝缘子试运行 ,从 1 994年开始 ,逐步在全省电网输电线路所处的Ⅲ、Ⅳ级重污区 ( 35kV～ 330kV)直线串上大面积挂网试运行。取得了较为显著的防污闪效果。但是 ,合成绝缘子在挂网运行当中 ,也发生过多次闪络故障。本文就青海电网合成绝缘子运用及运行状况进行了详细的统计分析 。Organic composite insulator having weight light, anti-dirty capability strong, hydro-quality superiority etc, it exerts active action in electric power netting preventing pollution flashover, and is widely applied in heavy pollution flashover, alp, and remote area etc. Qinghai electric power netting first hung netting to test running composite insulator since 1992.From 1994 beginning, it hung netting step by step to test running in all Province Ⅲ,Ⅳ grade heavy pollution flashover area (35kV-330kV). It acquires remarkable effect to preventing pollution flashover. Whereas, when composite insulator hung netting to test running, it happened time after time flashover failure. The paper analyses in detail composite insulator's working and running status in Qinghai electric power netting, and summarizes accident reason.\ Composite insulator Hydro-quality Pollution flashover Mechanical strength Analysis
