style="text-indent:25px">一般在住宅樓中大家可能覺(jué)得變壓器好像不是很常見(jiàn)，但其實(shí)它可能都是隱藏在電箱背后的，只不過(guò)大家看不見(jiàn)。湖南變壓器檢測(cè)儀</p><p style="text-indent:25px">配電變壓器的防雷保護(hù)接線具體要求如下： (1)一般要求避雷器安裝在跌開(kāi)式熔斷器和變壓器之間，避雷器要求盡量靠近變壓器安裝，距離越近越好。 (2)避雷器的接地線應(yīng)與變壓器低壓繞組中性點(diǎn)及變壓器金屬外殼連接在一起共同接地，亦稱作“三位一體”的接地方式。這種接法的目的是保證當(dāng)變壓器高壓側(cè)受雷擊引起避雷器放電時(shí)，變壓器主絕緣所承受的電壓僅是避雷器的殘壓，而接地裝置上的電壓并不作用在變壓器主絕緣上，使避雷器與變壓器得到較好的絕緣配合，能減少高、低壓繞組間和高壓繞組對(duì)變壓器外殼之間發(fā)生絕緣擊穿的危險(xiǎn)。 (3)對(duì)于低壓，架空線路引出3~10kV，Y，yn0配電變壓器，為防止低壓側(cè)落雷造成絕緣擊穿事故，要求在配電變壓器低壓出線上安裝一組低壓避雷器，這樣不僅可保護(hù)變壓器的低壓繞組，同時(shí)還能保護(hù)當(dāng)雷電波從低壓繞組折換到高壓繞組時(shí)，不致使高壓繞組絕緣損壞。湖南變壓器檢測(cè)儀</p><p
