Study on influence of ice disaster on properties of composite insulator
摘要
湖南是一个冰冻重灾区
冰冻灾害给电网的安全运行带来巨大危害
如大量的断线、掉串等。本文通过对运行复合绝缘子在冰冻灾害前后的机电性能试验研究
认为冰冻灾害前后复合绝缘子机电性能无明显变化
不存在遗留隐患
仍然能安全稳定运行
并提出在重冰区宜采用间插特大伞裙设计的防冰型复合绝缘子。
Abstract
Hunan is in a severe ice disaster area and it had produced serious harm to the safe and stable operation of power grid
such as power line breakage and insulator strings dropping.The mechanical properties test result shows that electrical and mechanical properties of composite insulators did not change significantly before and after freezing and there is no hidden trouble left after tests.It is strongly recommended that the anti-ice composite insulator with special shed should be adopted in the heavy frozen area.
