    2、高壓配電線路電纜分(fen)支(zhi)箱(xiang)，環網(wang)柜防雷分(fen)析 

　　配電(dian)(dian)(dian)(dian)線路(lu)中(zhong)(zhong)，電(dian)(dian)(dian)(dian)纜之間(jian)，電(dian)(dian)(dian)(dian)力和(he)其(qi)他設(she)備(bei)之間(jian)進行連接(jie)的中(zhong)(zhong)間(jian)部(bu)件就是(shi)電(dian)(dian)(dian)(dian)纜分支(zhi)箱(xiang)，具(ju)有全封閉、耐腐蝕、絕緣性能(neng)好、連接(jie)方式靈活(huo)、方便(bian)、安全性能(neng)高等特征，得到了越(yue)來(lai)越(yue)多的應用(yong)；在鋼板金屬柜(ju)中(zhong)(zhong)放(fang)置一組高壓開(kai)關設(she)備(bei)組成了環(huan)網柜(ju)，具(ju)有體積小(xiao)、價格低廉、供電(dian)(dian)(dian)(dian)安全等優點。高壓 配電(dian)(dian)(dian)(dian)線路(lu)中(zhong)(zhong)電(dian)(dian)(dian)(dian)纜分支(zhi)箱(xiang)，環(huan)網柜(ju)等如果沒有防雷(lei)(lei)設(she)施，那(nei)么一旦在高壓配電(dian)(dian)(dian)(dian)線路(lu)中(zhong)(zhong)巡受雷(lei)(lei)電(dian)(dian)(dian)(dian)過電(dian)(dian)(dian)(dian)壓，那(nei)么隨著架空線路(lu)，雷(lei)(lei)電(dian)(dian)(dian)(dian)波(bo)就侵入電(dian)(dian)(dian)(dian)纜線路(lu)，不管是(shi)電(dian)(dian)(dian)(dian)纜分支(zhi)箱(xiang)還是(shi)環(huan)網柜(ju)中(zhong)(zhong)，電(dian)(dian)(dian)(dian)纜頭都(dou)是(shi)電(dian)(dian)(dian)(dian)纜線路(lu)容易被擊穿(chuan)的地方，電(dian)(dian)(dian)(dian)纜頭一旦被絕緣擊穿(chuan)，就會成為(wei)永久性的故障，因此(ci)，在高壓配電(dian)(dian)(dian)(dian)線路(lu)中(zhong)(zhong)進行電(dian)(dian)(dian)(dian)纜分支(zhi)箱(xiang)和(he)環(huan)網柜(ju)的防雷(lei)(lei)是(shi)非常重要的。 

    二、高壓配電線(xian)路防(fang)雷措施(shi) 

    1、提高(gao)高(gao)壓配電線路絕緣(yuan)水平 

    和直(zhi)擊雷(lei)過電(dian)(dian)(dian)壓幅值相(xiang)比(bi)，感應(ying)雷(lei)過電(dian)(dian)(dian)壓幅值較(jiao)(jiao)(jiao)小(xiao)，但是(shi)由(you)于雷(lei)電(dian)(dian)(dian)的(de)活動以及放(fang)(fang)電(dian)(dian)(dian)的(de)形式影響了感應(ying)雷(lei)過電(dian)(dian)(dian)壓，因(yin)(yin)此，其幅值變化的(de)范圍較(jiao)(jiao)(jiao)大。如果雷(lei)云的(de)活動距離與高(gao)壓配(pei)電(dian)(dian)(dian)線(xian)路(lu)(lu)較(jiao)(jiao)(jiao)近，并且有云對地放(fang)(fang)電(dian)(dian)(dian)發生時，感應(ying)雷(lei)的(de)過電(dian)(dian)(dian)壓的(de)幅值就比(bi)較(jiao)(jiao)(jiao)大，這樣容易影響到高(gao)壓 配(pei)電(dian)(dian)(dian)線(xian)路(lu)(lu)，從而發生絕緣(yuan)擊穿現象；架(jia)空線(xian)路(lu)(lu)主(zhu)要受到感應(ying)雷(lei)過電(dian)(dian)(dian)壓的(de)影響，目前配(pei)電(dian)(dian)(dian)網中廣泛采用(yong)的(de)絕緣(yuan)線(xian)路(lu)(lu)，能(neng)夠一定程度上使(shi)得配(pei)電(dian)(dian)(dian)線(xian)路(lu)(lu)的(de)絕緣(yuan)水平(ping)提(ti)高(gao)。然而，對防(fang)雷(lei)來說，由(you)于架(jia)空導線(xian)絕緣(yuan)主(zhu)要解決的(de)是(shi)豎相(xiang)問題，因(yin)(yin)此，不(bu)能(neng)根本上解決配(pei)電(dian)(dian)(dian)線(xian)路(lu)(lu)的(de)防(fang)雷(lei)危害(hai)。通常通過使(shi)用(yong)沖擊放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)壓比(bi)較(jiao)(jiao)(jiao)高(gao)的(de)絕緣(yuan)子，從而使(shi)得配(pei)電(dian)(dian)(dian)線(xian)路(lu)(lu)的(de)絕緣(yuan)水平(ping)提(ti)高(gao)，最終使(shi)得配(pei)電(dian)(dian)(dian)線(xian)路(lu)(lu)的(de)防(fang)雷(lei)能(neng)力得到提(ti)高(gao)。 

    2、 加強對架空絕緣(yuan)導線(xian)雷(lei)擊斷線(xian)的防護 

    （1）可以提高(gao)配電(dian)線(xian)(xian)路(lu)(lu)局部的(de)絕(jue)(jue)緣(yuan)(yuan)水平。基于(yu)線(xian)(xian)路(lu)(lu)造價的(de)考慮，利用架空絕(jue)(jue)緣(yuan)(yuan)導線(xian)(xian)使得(de)局部絕(jue)(jue)緣(yuan)(yuan)得(de)到(dao)強化，這樣放電(dian)僅僅從絕(jue)(jue)緣(yuan)(yuan)加強邊(bian)緣(yuan)(yuan)或(huo)者(zhe)占穿絕(jue)(jue)緣(yuan)(yuan)皮反擊(ji)穿導線(xian)(xian)，從而使得(de)線(xian)(xian)路(lu)(lu)的(de)沖(chong)擊(ji)放電(dian)電(dian)壓(ya)得(de)到(dao)提高(gao)。 

    （2）對配(pei)(pei)(pei)電線(xian)(xian)(xian)路(lu)(lu)安裝(zhuang)避(bi)雷(lei)器，進行(xing)防雷(lei)。高壓(ya)配(pei)(pei)(pei)電線(xian)(xian)(xian)路(lu)(lu)借鑒輸電線(xian)(xian)(xian)路(lu)(lu)采用(yong)避(bi)雷(lei)器能夠(gou)(gou)有(you)效(xiao)防雷(lei)，在(zai)配(pei)(pei)(pei)電線(xian)(xian)(xian)路(lu)(lu)中(zhong)安裝(zhuang)避(bi)雷(lei)器，從而能夠(gou)(gou)有(you)效(xiao)保(bao)護架空絕(jue)緣線(xian)(xian)(xian)路(lu)(lu)。由于(yu)長(chang)期承受(shou)工頻(pin)電樂(le)，并且間歇承受(shou)雷(lei)電過電壓(ya)以(yi)及工頻(pin)續(xu)流的(de)影(ying)響，因此無間隙避(bi)雷(lei)器非常(chang)容易發生老化(hua)現(xian)象，從而容易出現(xian)故(gu)障，使得配(pei)(pei)(pei)電線(xian)(xian)(xian)路(lu)(lu)的(de)安全(quan)(quan)受(shou)到(dao)影(ying)響。基(ji)于(yu)此，高壓(ya)配(pei)(pei)(pei)電線(xian)(xian)(xian)路(lu)(lu)中(zhong)，選(xuan)擇(ze)氧(yang)化(hua)鋅避(bi)雷(lei)器，并且選(xuan)擇(ze)配(pei)(pei)(pei)電線(xian)(xian)(xian)路(lu)(lu)中(zhong)容易遭受(shou)雷(lei)擊的(de)位置進行(xing)安裝(zhuang)，同時，在(zai)容易遭受(shou)雷(lei)擊的(de)線(xian)(xian)(xian)路(lu)(lu)的(de)配(pei)(pei)(pei)電變(bian)壓(ya)器等設備處安裝(zhuang)氧(yang)化(hua)鋅避(bi)雷(lei)器，全(quan)(quan)面保(bao)護配(pei)(pei)(pei)電線(xian)(xian)(xian)路(lu)(lu)。 

    （3）為預(yu)防(fang)絕緣導線絕緣層擊(ji)穿，采用(yong)絕緣子兩端并聯放電間(jian)隙(xi)的(de)(de)方式。將間(jian)隙(xi)放電電壓(ya)調整到不小于絕緣子的(de)(de)沖擊(ji)電壓(ya)，那(nei)么配(pei)電線路(lu)的(de)(de)雷電放電就(jiu)會發生在保護間(jian)隙(xi)，這樣就(jiu)有效解決了絕緣導線遭受雷擊(ji)斷(duan)線現象。 

    （4）高(gao)(gao)壓(ya)(ya)配電(dian)線(xian)路(lu)配電(dian)設(she)備(bei)的(de)(de)(de)防(fang)(fang)(fang)(fang)雷(lei)(lei)。高(gao)(gao)壓(ya)(ya)配電(dian)線(xian)路(lu)中，對(dui)配電(dian)變壓(ya)(ya)器(qi)(qi)保(bao)護(hu)(hu)(hu)需要(yao)(yao)在低壓(ya)(ya)側(ce)(ce)安(an)(an)裝(zhuang)(zhuang)(zhuang)低壓(ya)(ya)避(bi)(bi)雷(lei)(lei)器(qi)(qi)，同(tong)時(shi)保(bao)證高(gao)(gao)壓(ya)(ya)側(ce)(ce)避(bi)(bi)雷(lei)(lei)器(qi)(qi)，低壓(ya)(ya)避(bi)(bi)雷(lei)(lei)器(qi)(qi)，低壓(ya)(ya)側(ce)(ce)中性點，以(yi)及變壓(ya)(ya)器(qi)(qi)外(wai)殼同(tong)時(shi)接地，實現(xian)四(si)點共地。基于(yu)電(dian)網(wang)(wang)(wang)運行(xing)安(an)(an)全(quan)穩(wen)定(ding)的(de)(de)(de)考慮，高(gao)(gao)壓(ya)(ya)電(dian)網(wang)(wang)(wang)中，安(an)(an)裝(zhuang)(zhuang)(zhuang)了一(yi)定(ding)數量的(de)(de)(de)開(kai)關和(he)刀閘(zha)，對(dui)這些設(she)備(bei)的(de)(de)(de)防(fang)(fang)(fang)(fang)雷(lei)(lei)不到位，非(fei)常(chang)容易在雷(lei)(lei)害事故發生時(shi)，造成對(dui)開(kai)關設(she)備(bei)的(de)(de)(de)損(sun)害，因此(ci)，配電(dian)網(wang)(wang)(wang)線(xian)路(lu)防(fang)(fang)(fang)(fang)雷(lei)(lei)保(bao)護(hu)(hu)(hu)中，開(kai)關設(she)備(bei)的(de)(de)(de)防(fang)(fang)(fang)(fang)雷(lei)(lei)是十分重(zhong)要(yao)(yao)的(de)(de)(de)有(you)機組成部分，為(wei)了防(fang)(fang)(fang)(fang)止(zhi)高(gao)(gao)壓(ya)(ya) 配電(dian)線(xian)路(lu)中防(fang)(fang)(fang)(fang)雷(lei)(lei)存在缺陷，必須通過在開(kai)關，刀閘(zha)兩側(ce)(ce)都安(an)(an)裝(zhuang)(zhuang)(zhuang)避(bi)(bi)雷(lei)(lei)器(qi)(qi)的(de)(de)(de)方(fang)式，對(dui)其進行(xing)防(fang)(fang)(fang)(fang)雷(lei)(lei)保(bao)護(hu)(hu)(hu)。高(gao)(gao)壓(ya)(ya)配電(dian)線(xian)路(lu)中，電(dian)纜分支箱(xiang)以(yi)及環(huan)(huan)網(wang)(wang)(wang)柜是應用越來越多的(de)(de)(de)設(she)備(bei)，對(dui)其防(fang)(fang)(fang)(fang)雷(lei)(lei)也尤(you)為(wei)重(zhong)要(yao)(yao)。通常(chang)采(cai)用在高(gao)(gao)壓(ya)(ya)配電(dian)線(xian)路(lu)的(de)(de)(de)每個單元(yuan)增加避(bi)(bi)雷(lei)(lei)器(qi)(qi)或者有(you)選擇的(de)(de)(de)在環(huan)(huan)網(wang)(wang)(wang)單元(yuan)安(an)(an)裝(zhuang)(zhuang)(zhuang)避(bi)(bi)雷(lei)(lei)器(qi)(qi)。為(wei)了實現(xian)防(fang)(fang)(fang)(fang)雷(lei)(lei)效(xiao)果(guo)，具(ju)有(you)防(fang)(fang)(fang)(fang)爆脫(tuo)離功能(neng)以(yi)及免維護(hu)(hu)(hu)氧(yang)化鋅避(bi)(bi)雷(lei)(lei)器(qi)(qi)效(xiao)果(guo)良好。由于(yu)具(ju)有(you)體積小(xiao)(xiao)，方(fang)便安(an)(an)裝(zhuang)(zhuang)(zhuang)，質量小(xiao)(xiao)，防(fang)(fang)(fang)(fang)水，防(fang)(fang)(fang)(fang)爆，密閉(bi)性能(neng)強等優點，在高(gao)(gao)壓(ya)(ya)配電(dian)線(xian)路(lu)中，通常(chang)選擇型號為(wei) HY5WS-12.7/50 避(bi)(bi)雷(lei)(lei)器(qi)(qi)。
