style="text-indent:25px">玻璃絕緣子自爆的原因可分為產(chǎn)品自身質(zhì)量原因與外部運(yùn)行環(huán)境原因兩類(lèi)，產(chǎn)品質(zhì)量由于主要是玻璃絕緣子玻璃件內(nèi)部含有雜質(zhì)顆粒外部原因，主要是污穢和溫差變化。雜質(zhì)顆粒位于玻璃件的內(nèi)部張應(yīng)力層時(shí)，產(chǎn)生自爆的概率更高，因玻璃本身是一種脆性材料，耐壓但不耐拉，所以玻璃的大部分破碎是張應(yīng)力引發(fā)的。在積污、受潮和電場(chǎng)三者同時(shí)作用下，絕緣子表面泄露電流過(guò)大，產(chǎn)生部分干帶，干帶位置發(fā)生空氣擊穿時(shí)，產(chǎn)生的電弧將蝕傷玻璃傘裙，當(dāng)蝕傷深度較深時(shí)將造成自爆。如果上述過(guò)程中絕緣子遭受雷擊，已經(jīng)受到電弧侵蝕的玻璃絕緣子自爆概率將大幅增加。積污過(guò)重是其中關(guān)鍵，可能是積污鹽密過(guò)高，也可能是污穢中金屬粉末顆粒過(guò)多。</p><p style="text-indent:25px">對(duì)瓷絕緣子而言，當(dāng)絕緣子頭部瓷件存在細(xì)微裂紋等缺點(diǎn)，隨著運(yùn)行中潮氣的侵入，絕緣子頭部絕緣電阻降低（形成零值絕緣子），一旦絕緣子串遭受雷擊或其他原因造成的閃絡(luò)，由于頭部電阻很小、沿傘盤(pán)放電距離較長(zhǎng)電阻相對(duì)較大，所以大部分能量都從瓷絕緣子頭部的放電通道泄放，電弧從絕緣子頭部通過(guò)時(shí)產(chǎn)生的熱量使絕緣子炸開(kāi)，產(chǎn)生斷串。瓷絕緣子的膠裝界面工藝不良、瓷件材質(zhì)不良會(huì)導(dǎo)致零值絕緣子的產(chǎn)生瓷絕緣子膠裝界面存在瓷、水泥、鋼等散熱膨脹系數(shù)不同的材質(zhì)，一般需要涂覆瀝青等材料作為緩沖層，當(dāng)如緩沖層太薄或與瓷、水泥等材質(zhì)配合度不夠，絕緣子承受外界溫度變化導(dǎo)致界面開(kāi)裂。瓷絕緣子瓷件中存在砂眼，或瓷件晶粒尺寸過(guò)大，長(zhǎng)期運(yùn)行中瓷件內(nèi)部產(chǎn)生微裂紋，裂紋擴(kuò)展到一定程度導(dǎo)致低零值絕緣子的產(chǎn)生。關(guān)于絕緣子的知識(shí)你知道多少？</p><div

style="text-indent:25px">常見(jiàn)的絕緣子的材質(zhì)有哪些？南京瓷針式絕緣子</p><p style="text-indent:25px">絕緣子的放電特性在工頻電壓、操作過(guò)電壓、雷電過(guò)電壓下是不一樣的。工頻電壓下的絕緣配合，一般只要求爬距滿(mǎn)足要求。畢竟，工頻電壓是長(zhǎng)時(shí)間施加在絕緣子上的。操作過(guò)電壓與雷電過(guò)電壓的放電特性，主要受絕緣子串長(zhǎng)影響，其中，操作過(guò)電壓為內(nèi)部過(guò)電壓，故不考慮塔高的影響，而雷電過(guò)電壓為外部過(guò)電壓，需要考慮塔高。另外，操作過(guò)電壓的過(guò)電壓波形更逼近于工頻電壓的波形，所以，零值絕緣子會(huì)影響其放電特性，故在進(jìn)行操作過(guò)電壓下的耐張絕緣子計(jì)算時(shí)，需要考慮比懸垂串多加一定數(shù)量的零值絕緣子；而雷電過(guò)電壓因放電時(shí)間很短而主要考慮有效串長(zhǎng)，零值絕緣子不會(huì)降低絕緣子串的有效串長(zhǎng)，所以在進(jìn)行雷電過(guò)電壓的絕緣配合時(shí)不必考慮添加零值絕緣子。不管是工頻電壓還是操作過(guò)電壓與雷電過(guò)電壓，海拔升高后，因受空氣密度的影響，絕緣子表面的去游離特性會(huì)變差，因而，都需要進(jìn)行海拔的修正。南京瓷針式絕緣子</p><p
