摘要
分析了线路避雷器的防雷原理,根据易遭受雷击的110kV线路采用复合绝缘外套金属氧化物避雷器后的实际运行情况,对避雷器投运前后线路跳闸数据进行分析对比,从而说明了线路避雷器确实具有一定的防雷效果。最后对线路避雷器的一些使用问题提出了建议。
This paper analyzes the theory of line attesters. According to the operation results of the 110 kV lines in Zengcheng, Guangdong that are equipped with polymeric insulating overcoat arresters, an analytical comparison is made on the trip-out data of the lines to illuminate the good effects of the arresters. Lastly some suggestions are offered on the use of line arresters.
