相對于油式變壓器，scb10干式變(bian)壓器因沒有油，也就沒有火災、爆炸、污(wu)染等(deng)題目，故電(dian)氣(qi)規(gui)范(fan)(fan)、規(gui)程等(deng)均不要求scb10干(gan)式(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)置于單先房間內。特別是新(xin)的(de)系(xi)列(lie)(lie)(lie)，SCB9 系(xi)列(lie)(lie)(lie)三(san)相環繞糾纏式(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)，SCB10 系(xi)列(lie)(lie)(lie)三(san)相箔式(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)SCB9 系(xi)列(lie)(lie)(lie)三(san)相箔式(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)。其電(dian)壓(ya)(ya)等(deng)級(ji)一(yi)般(ban)都在(zai)6-35KV 范(fan)(fan)圍內，較大容量可達25MVA。現結合SC 系(xi)列(lie)(lie)(lie)三(san)相環繞糾纏式(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)，對(dui)scb10干(gan)式(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)的(de)特點及(ji)安裝調試做具體闡述。損(sun)耗(hao)和噪聲降到了新(xin)的(de)水平，更為變(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)與低壓(ya)(ya)屏(ping)置于統一(yi)配電(dian)室內創(chuang)造了前提。

　scb10-500/35變(bian)壓器作用：

　　1.是發(fa)電(dian)(dian)廠和變(bian)(bian)電(dian)(dian)所的(de)主要(yao)(yao)設備之一。變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的(de)作用(yong)是多方(fang)面(mian)的(de)不僅能升高電(dian)(dian)壓(ya)(ya)(ya)把(ba)電(dian)(dian)能送到用(yong)電(dian)(dian)地區，還(huan)能把(ba)電(dian)(dian)壓(ya)(ya)(ya)降低為各級使(shi)用(yong)電(dian)(dian)壓(ya)(ya)(ya)，以滿足用(yong)電(dian)(dian)的(de)需要(yao)(yao)。總之，升壓(ya)(ya)(ya)與(yu)降壓(ya)(ya)(ya)都必須由變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)來完成(cheng)。在電(dian)(dian)力(li)系統傳送電(dian)(dian)能的(de)過程中(zhong)，必然會產生電(dian)(dian)壓(ya)(ya)(ya)和功率(lv)兩部分損(sun)耗(hao)，在輸送同一功率(lv)時(shi)電(dian)(dian)壓(ya)(ya)(ya)損(sun)耗(hao)與(yu)電(dian)(dian)壓(ya)(ya)(ya)成(cheng)反比(bi)，功率(lv)損(sun)耗(hao)與(yu)電(dian)(dian)壓(ya)(ya)(ya)的(de)平(ping)方(fang)成(cheng)反比(bi)。利用(yong)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)提(ti)高電(dian)(dian)壓(ya)(ya)(ya)，減少(shao)了送電(dian)(dian)損(sun)失。
