| 摘 要： | 佛山供电局220kV南北线路发生污闪跳闸，对该线路的绝缘子进行性能评价试验，试验结果表明瓷质绝缘子具有较好的运行性能及可靠性。分析认为，发生污闪的主要原因是大气污染加重导致绝缘子污秽耐受电压降低，爬电比距不能满足环境变化对于外绝缘配置的要求。最后．提出防止线路发生污闪的相关对策。 |
| 关 键 词： | 污闪 瓷质绝缘子 污秽耐受电压 |

| Abstract: | In view of the pollution-flashover-caused tripping operation of 220 kV Nanbei Line of Foshan Power Supply Bureau, a performance estimation test on insulators removed from the line was conducted, the results of which showed the favorable operation characteristics and reliability of porcelain insulators. Upon analysis, this paper points out that the main reason of the pollution flashover was that the increased air pollution led to the reduction in the pollution withstand voltage of insulators, and the specific creepage distance could not meet the requirement of the changed environment on the configuration of external insulation. Lastly, countermeasures against pollution flashover on lines are put forward. |
| Keywords: | pollution flashover porcelain insulator pollution withstand voltage |
