500kV耐张塔内转角跳线串合成绝缘子舞动脱落原因分析

Cause Analysis of Galloping Shedding for Composite Insulators with Angle Jumper String in 500kV Tension Tower

针对数起500kV耐张塔内转角跳线合成绝缘子舞动脱落的情况,结合合成绝缘子的特点、耐张塔内转角跳线的特殊性进行分析,发现耐张塔内转角跳线加装合成绝缘子的问题,提出防止耐张塔内转角跳线串舞动脱落的建议。

Aiming at several incidents of galloping shedding of composite insulators of angle jumper string in 500 kV tension tower, this paper analyzes the characteristics of composite insulators and the particularity of the angle jumper string in the tension tower and finds out the problems of adding composite insulators to the angle jumper string in the tension tower. And the paper also raises some suggestions to prevent the galloping shedding of the angle jumper string in the tension tower.
