一、絕緣子串的作用是什么

絕(jue)(jue)(jue)緣(yuan)子(zi)(zi)串指兩(liang)個(ge)或多個(ge)絕(jue)(jue)(jue)緣(yuan)子(zi)(zi)元件組合在一起，柔性懸(xuan)掛導線的組件。絕(jue)(jue)(jue)緣(yuan)子(zi)(zi)串是帶有固定和運行需(xu)要的保護(hu)裝置(zhi)，用(yong)于(yu)懸(xuan)掛導線并使導線與桿(gan)塔(ta)和大地(di)絕(jue)(jue)(jue)緣(yuan)，那么絕(jue)(jue)(jue)緣(yuan)子(zi)(zi)串的作用(yong)是什么呢(ni)？

絕緣子串起著隔離(li)作用(yong)，其實不是有絕緣的作用(yong)，主(zhu)要是防(fang)止接地不合格(ge)的情況下(xia)感(gan)應電傷人。

二、絕緣子串和電壓的關系是什么

在(zai)交流電(dian)(dian)(dian)(dian)壓(ya)作用下的絕(jue)(jue)緣(yuan)(yuan)子串，無(wu)論其片(pian)(pian)數多(duo)少，其分(fen)布(bu)電(dian)(dian)(dian)(dian)壓(ya)（絕(jue)(jue)緣(yuan)(yuan)子串在(zai)系統(tong)運行(xing)相(xiang)電(dian)(dian)(dian)(dian)壓(ya)下，每一片(pian)(pian)絕(jue)(jue)緣(yuan)(yuan)子所承受(shou)(shou)到的電(dian)(dian)(dian)(dian)壓(ya)）曲線(xian)(xian)都具(ju)相(xiang)同的特(te)征：電(dian)(dian)(dian)(dian)壓(ya)分(fen)布(bu)曲線(xian)(xian)呈兩端高、中(zhong)間低的馬鞍形(xing)。這是(shi)由于(yu)絕(jue)(jue)緣(yuan)(yuan)子的自(zi)身電(dian)(dian)(dian)(dian)容(rong)(rong)C以及對導線(xian)(xian)雜散(san)電(dian)(dian)(dian)(dian)容(rong)(rong)C1、對地(di)的雜散(san)電(dian)(dian)(dian)(dian)容(rong)(rong)Ce所致。從分(fen)布(bu)電(dian)(dian)(dian)(dian)壓(ya)值中(zhong)可以看出，靠近導線(xian)(xian)側的數片(pian)(pian)絕(jue)(jue)緣(yuan)(yuan)子所承受(shou)(shou)的電(dian)(dian)(dian)(dian)壓(ya)較高，電(dian)(dian)(dian)(dian)場強度較大。

絕(jue)緣子(zi)(zi)(zi)串(chuan)電(dian)(dian)壓(ya)(ya)(ya)(ya)分(fen)布規律：由(you)于每個絕(jue)緣子(zi)(zi)(zi)的(de)(de)金屬部(bu)分(fen)與桿(gan)(gan)塔（地）間、導(dao)(dao)線間均(jun)存在雜散電(dian)(dian)容，絕(jue)緣子(zi)(zi)(zi)串(chuan)中(zhong)每個絕(jue)緣子(zi)(zi)(zi)實際所分(fen)擔(dan)的(de)(de)電(dian)(dian)壓(ya)(ya)(ya)(ya)并不相同。沿絕(jue)緣子(zi)(zi)(zi)串(chuan)的(de)(de)電(dian)(dian)壓(ya)(ya)(ya)(ya)分(fen)布是極不均(jun)勻(yun)的(de)(de)，靠近導(dao)(dao)線的(de)(de)絕(jue)緣子(zi)(zi)(zi)電(dian)(dian)壓(ya)(ya)(ya)(ya)降最大，離導(dao)(dao)線愈遠(yuan)的(de)(de)絕(jue)緣子(zi)(zi)(zi)兩端壓(ya)(ya)(ya)(ya)降愈小，當絕(jue)緣子(zi)(zi)(zi)靠近桿(gan)(gan)塔橫(heng)擔(dan)時，絕(jue)緣子(zi)(zi)(zi)電(dian)(dian)壓(ya)(ya)(ya)(ya)降又升高。絕(jue)緣子(zi)(zi)(zi)串(chuan)愈長(chang)，電(dian)(dian)壓(ya)(ya)(ya)(ya)分(fen)布愈不均(jun)勻(yun)，愈容易導(dao)(dao)致某些部(bu)位的(de)(de)絕(jue)緣損壞。
