摘要
变电站支柱绝缘子的合理选型可有效防止污闪。分析了配电网变电站支柱绝缘子污闪事故原因,提出了解决绝缘子污闪的方法是避免配电网变电站室内环境污湿和有效提高绝缘子的爬电比距。对7种支柱绝缘子进行了防污闪能力的选型研究,并根据研究结果选取了最优型号。
The proper model selection of the post insulator in substation can effectively prevent the flashover. The flashover fault causes of the post insulator in the distribution substation is analyzed. To keep the trans- former chamber dry and clean and effectively increase the creepage distance of the insulators are the way to pre- vent the flashover of the insulator. Through the model selection research on the flashover prevention capability of 7 kinds of insulators, the best model is chosen according to the research result.
