干式變壓(ya)器(qi)是一個(ge)巨大的(de)部(bu)件。里(li)面有(you)很(hen)多缺口。一般來說，電壓(ya)和電流(liu)可以在(zai)間(jian)(jian)隙(xi)(xi)之(zhi)間(jian)(jian)傳輸(shu)。如果你不(bu)小心(xin)，你會觸電的(de)。干式變壓(ya)器(qi)的(de)間(jian)(jian)隙(xi)(xi)也應加以保(bao)護(hu)，否則容易(yi)失(shi)效(xiao)。干式變壓(ya)器(qi)的(de)間(jian)(jian)隙(xi)(xi)保(bao)護(hu)要有(you)一定的(de)技術(shu)支(zhi)持，那么(me)干式變壓(ya)器(qi)的(de)間(jian)(jian)隙(xi)(xi)保(bao)護(hu)是什么(me)？

間隙(xi)保護是指線(xian)路(lu)的(de)(de)兩(liang)(liang)極由角(jiao)棒組(zu)成，一極固(gu)定(ding)在干式(shi)變壓器的(de)(de)絕緣上，與帶電(dian)(dian)導(dao)體連接，另一極接地。間隙(xi)擊穿后，電(dian)(dian)弧在角(jiao)條之間上升變長，當(dang)電(dian)(dian)弧電(dian)(dian)流變小時(shi)，可(ke)(ke)以自行(xing)熄滅。間隙(xi)保護技術(shu)的(de)(de)缺點是當(dang)電(dian)(dian)弧電(dian)(dian)流高于幾十安培(pei)時(shi)，不能(neng)自行(xing)熄滅。當(dang)雷電(dian)(dian)過電(dian)(dian)壓時(shi)，單相、兩(liang)(liang)相或(huo)三相間隙(xi)可(ke)(ke)能(neng)擊穿大地，導(dao)致(zhi)接地故(gu)障、兩(liang)(liang)相或(huo)三相短路(lu)故(gu)障，從(cong)而(er)

在其開發使用初期，電(dian)(dian)(dian)(dian)(dian)力設(she)備(bei)多通過(guo)裸導(dao)線(xian)架空(kong)線(xian)傳(chuan)輸電(dian)(dian)(dian)(dian)(dian)力，架空(kong)導(dao)線(xian)一般在距地面6 ~ 18m的空(kong)間(jian)(jian)內(nei)。雷(lei)電(dian)(dian)(dian)(dian)(dian)侵入波引起的雷(lei)電(dian)(dian)(dian)(dian)(dian)過(guo)電(dian)(dian)(dian)(dian)(dian)壓(ya)導(dao)致線(xian)路或設(she)備(bei)絕(jue)(jue)(jue)緣擊(ji)穿(chuan)(chuan)并損壞它們。當(dang)時(shi)，人們在線(xian)路或設(she)備(bei)上人為制造絕(jue)(jue)(jue)緣薄弱點，即間(jian)(jian)隙(xi)裝置。間(jian)(jian)隙(xi)擊(ji)穿(chuan)(chuan)電(dian)(dian)(dian)(dian)(dian)壓(ya)低于(yu)線(xian)路或設(she)備(bei)的雷(lei)電(dian)(dian)(dian)(dian)(dian)沖擊(ji)絕(jue)(jue)(jue)緣水平(ping)。在正常工作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)下，間(jian)(jian)隙(xi)被(bei)隔離和絕(jue)(jue)(jue)緣。雷(lei)電(dian)(dian)(dian)(dian)(dian)發生(sheng)(sheng)時(shi)，強過(guo)電(dian)(dian)(dian)(dian)(dian)壓(ya)引起間(jian)(jian)隙(xi)擊(ji)穿(chuan)(chuan)，產生(sheng)(sheng)接地保護，起到保護線(xian)路或設(she)備(bei)絕(jue)(jue)(jue)緣的作(zuo)用。

干(gan)(gan)(gan)式(shi)變(bian)(bian)壓(ya)(ya)(ya)器廠熱(re)情提醒我們的客戶：當您(nin)購買(mai)干(gan)(gan)(gan)式(shi)變(bian)(bian)壓(ya)(ya)(ya)器時，您(nin)必須(xu)檢(jian)查是否有間隙保(bao)護(hu)。如果沒有間隙保(bao)護(hu)，讓廠家趕緊做，否則干(gan)(gan)(gan)式(shi)變(bian)(bian)壓(ya)(ya)(ya)器在運行中會擊穿。關于(yu)干(gan)(gan)(gan)式(shi)變(bian)(bian)壓(ya)(ya)(ya)器的知識和各方(fang)面的故障問題，請咨(zi)詢我們的干(gan)(gan)(gan)式(shi)變(bian)(bian)壓(ya)(ya)(ya)器廠。我們有專業(ye)人員(yuan)為您(nin)解(jie)決(jue)問題！
