一、絕緣子串的作用是什么

絕(jue)緣(yuan)(yuan)(yuan)子(zi)(zi)串指兩個或(huo)多個絕(jue)緣(yuan)(yuan)(yuan)子(zi)(zi)元件組(zu)合(he)在一起，柔性懸(xuan)掛導線(xian)的組(zu)件。絕(jue)緣(yuan)(yuan)(yuan)子(zi)(zi)串是帶有固定和運(yun)行需要的保護裝置(zhi)，用于(yu)懸(xuan)掛導線(xian)并使導線(xian)與桿塔和大地絕(jue)緣(yuan)(yuan)(yuan)，那么絕(jue)緣(yuan)(yuan)(yuan)子(zi)(zi)串的作用是什么呢？

絕緣子串起著(zhu)隔離作用，其實不(bu)是有絕緣的作用，主要(yao)是防止接地不(bu)合格的情況下(xia)感(gan)應電(dian)傷(shang)人(ren)。

二、絕緣子串和電壓的關系是什么

在交(jiao)流電(dian)(dian)(dian)(dian)壓(ya)作用下的(de)(de)絕(jue)(jue)(jue)緣(yuan)(yuan)子(zi)串(chuan)，無論(lun)其(qi)片(pian)數多少，其(qi)分(fen)布(bu)(bu)電(dian)(dian)(dian)(dian)壓(ya)（絕(jue)(jue)(jue)緣(yuan)(yuan)子(zi)串(chuan)在系統運行相(xiang)電(dian)(dian)(dian)(dian)壓(ya)下，每(mei)一片(pian)絕(jue)(jue)(jue)緣(yuan)(yuan)子(zi)所(suo)承受到的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)）曲(qu)(qu)線(xian)都具(ju)相(xiang)同(tong)的(de)(de)特(te)征：電(dian)(dian)(dian)(dian)壓(ya)分(fen)布(bu)(bu)曲(qu)(qu)線(xian)呈兩(liang)端(duan)高、中間低的(de)(de)馬鞍形。這是由于絕(jue)(jue)(jue)緣(yuan)(yuan)子(zi)的(de)(de)自身(shen)電(dian)(dian)(dian)(dian)容C以及(ji)對導線(xian)雜散電(dian)(dian)(dian)(dian)容C1、對地(di)的(de)(de)雜散電(dian)(dian)(dian)(dian)容Ce所(suo)致。從分(fen)布(bu)(bu)電(dian)(dian)(dian)(dian)壓(ya)值中可(ke)以看出，靠近導線(xian)側的(de)(de)數片(pian)絕(jue)(jue)(jue)緣(yuan)(yuan)子(zi)所(suo)承受的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)較(jiao)高，電(dian)(dian)(dian)(dian)場(chang)強(qiang)度較(jiao)大(da)。

絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)子(zi)(zi)串電(dian)壓(ya)分布規律：由于每(mei)個(ge)絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)子(zi)(zi)的(de)金屬部(bu)分與桿(gan)塔(ta)（地(di)）間(jian)(jian)、導(dao)線(xian)(xian)間(jian)(jian)均存在雜散(san)電(dian)容，絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)子(zi)(zi)串中(zhong)每(mei)個(ge)絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)子(zi)(zi)實(shi)際所分擔(dan)的(de)電(dian)壓(ya)并(bing)不相(xiang)同。沿絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)子(zi)(zi)串的(de)電(dian)壓(ya)分布是(shi)極不均勻的(de)，靠(kao)近導(dao)線(xian)(xian)的(de)絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)子(zi)(zi)電(dian)壓(ya)降(jiang)最(zui)大，離(li)導(dao)線(xian)(xian)愈遠的(de)絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)子(zi)(zi)兩端壓(ya)降(jiang)愈小，當絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)子(zi)(zi)靠(kao)近桿(gan)塔(ta)橫擔(dan)時，絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)子(zi)(zi)電(dian)壓(ya)降(jiang)又升高。絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)子(zi)(zi)串愈長，電(dian)壓(ya)分布愈不均勻，愈容易(yi)導(dao)致(zhi)某些部(bu)位的(de)絕(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)損壞。
