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，金華瓷針式絕緣子、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，金華瓷針式絕緣子、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，金華瓷針式絕緣子，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。</p><div

絕緣子俗稱瓷瓶，它是用來(lái)支持導(dǎo)線的絕緣體。因此，絕緣子既要有良好的電氣性能，又要有足夠的機(jī)械強(qiáng)度。絕緣子的好壞對(duì)線路的可靠運(yùn)行是十分重要的。電容測(cè)試儀采用新型勵(lì)磁線圈進(jìn)行真空度的不拆卸測(cè)量,具有使用方便,不拆卸測(cè)量和測(cè)試精度高等優(yōu)點(diǎn),是一種實(shí)用的檢測(cè)儀器,適用于電力,鋼鐵,石化,紡織,煤炭,鐵路等部門。絕緣子按結(jié)構(gòu)可分為支持絕緣子、通常并不失掉絕緣性能;擊穿發(fā)生在絕緣子的內(nèi)部，通過(guò)鐵帽與鐵腳間瓷體放電，外表可能不見(jiàn)痕跡，但已失去絕緣性能，也可能因產(chǎn)生電弧使絕緣子完全破壞。對(duì)于擊穿，應(yīng)注重檢查鐵腳的放電痕跡和燒傷情況。
