二、三相組合式過電壓保護器的結構特點
前(qian)文已(yi)經(jing)簡單了解到了三相(xiang)(xiang)組合(he)式過(guo)電壓(ya)保(bao)護(hu)器(qi)(qi)是一(yi)種(zhong)新型的避雷器(qi)(qi),那么三相(xiang)(xiang)組合(he)式過(guo)電壓(ya)保(bao)護(hu)器(qi)(qi)的結構(gou)特(te)點有哪些么?
1、結(jie)構新穎獨特,四元(yuan)件星形接(jie)法,技術性能優異(yi),絕緣耐高(gao)壓,極大地利用和縮減(jian)了使用空(kong)間(jian)。
2、復合外(wai)套整體模壓,具有良好的密封、防(fang)爆、防(fang)潮性(xing)能,抗漏(lou)痕、抗電蝕(shi),耐污,憎水性(xing)好。
3、高壓電纜(lan)接線(xian),保證絕緣強度,安(an)裝靈活。
4、體積小,重量輕,節(jie)省(sheng)占地(di),特別適合(he)在各種開關柜內安裝(既(ji)可垂直安裝,也可水平安裝)。
