避雷器均壓環(huán)

    目前避雷器均壓環(huán)按電壓等級分有110kV避雷器均壓環(huán)、220kV避雷器均壓環(huán)、330kV避雷器均壓環(huán)、500kV避雷器均壓環(huán)、550kV避雷器均壓環(huán)、750kV避雷器均壓環(huán)、800kV避雷器均壓環(huán)、1000kV避雷器均壓環(huán).....

   避雷器均壓環(huán)作用

   由于高壓避雷器對地有雜散電容,使得沿避雷器的電壓分布不均勻,這樣電壓高的地方就容易發(fā)生損壞,所以加一個(gè)避雷器均壓環(huán),用來均衡對地雜散電容,使電壓分布均勻,不發(fā)生局部擊穿而損壞。電壓等級越高,對地雜散電容越大。
