摘要
对500 kV的全尺寸绝缘子进行覆冰闪络试验,得到了在不同覆冰条件下的闪络电压值,据此设计不同覆冰条件下具有95%耐受概率所需的线路绝缘子最优串长。最后提出改变绝缘子配置和使用防冰涂料等综合方式来提高绝缘子防冰效果的措施。
Icing flashover test is conducted on 500 kV full-length insulators and magnitudes of flashover voltage in different icing conditions are concluded. According to the test, the length of icing insulator strings with 95% probability of tolerance voltage in different icing thickness is designed. Furthermore, the paper put forward comprehensive methods by changing configuration and painting anti-icing coating to improve the anti-icing effect of insulators.
