| 耐污绝缘子主要是采取增加或加大绝缘子伞裙或伞棱的措施以增加绝缘子的爬电距离，以提高绝缘子污秽状态下的电气强度。同时还采取改变伞裙结构形状以减少表面自然积污量，来提高绝缘子的抗污闪性能。耐污绝缘子的爬电比距一般要比普通绝缘子提高20%～30%，甚至更多。中国电网污闪多发的地区习惯采用双层伞结构形状的耐污绝缘子，此种绝缘子自清洗能力强，易于人工清扫。 Pollution-resistant insulators mainly take measures to increase or increase insulator umbrella skirt or umbrella edge to increase the creepage distance of insulators, so as to improve the electrical strength ofinsulatorswww.fenqieji.net.cnwww.qiezhiji.net.cnwww.weishengzhiji.com.cnwww.gangxianwei.net.cn www.wushuichulii.cnwww.jiedixuanxian.cnunder contaminated condition. At the same time, the structure of umbrella skirt is changed to reduce the amount of natural contamination on the surface, so as to improve the anti-pollution flashover performance of insulators. The creepage ratio of pollution-resistant insulators is generally 20%-30% higher than that of ordinary insulators, or even more. In areas where pollution flashover occurs frequently in China's power grid, pollution-resistant insulators with double umbrella structure are used, which have strong self-cleaning ability and are easy to be cleaned manually. |
