　　寧(ning)夏電力工(gong)程安(an)裝公司生產的(de)干(gan)式變壓器(qi)：由硅鋼板組成(cheng)的(de)鐵芯和環氧樹(shu)脂(zhi)鑄(zhu)入的(de)線圈(quan)組成(cheng)，在高低壓線圈(quan)之(zhi)間放置絕(jue)緣筒增加電絕(jue)緣，并通過墊塊支撐(cheng)和約束線圈(quan)，該零件(jian)(jian)重復的(de)緊(jin)固件(jian)(jian)均具有(you)防松性(xing)能。機械強度好，抗裂性(xing)好，耐濕性(xing)好，散熱效果好。干(gan)式變壓器(qi)：適用于間歇過載或緊(jin)急過載操作(zuo)。

　　干式變(bian)壓(ya)器(qi)(qi)(qi)(qi)繞組(zu)散(san)(san)熱只是一種變(bian)壓(ya)器(qi)(qi)(qi)(qi)，因(yin)為(wei)干式變(bian)壓(ya)器(qi)(qi)(qi)(qi)繞組(zu)散(san)(san)熱是使用(yong)空氣自(zi)然散(san)(san)熱或強制風冷(leng)(與風扇強制空氣對流)，不存在(zai)易燃(ran)易爆材料，廣泛應用(yong)于(yu)(yu)建筑物地下室等苛刻場所。與油(you)浸式變(bian)壓(ya)器(qi)(qi)(qi)(qi)不同，由于(yu)(yu)變(bian)壓(ya)器(qi)(qi)(qi)(qi)油(you)褶(zhe)積(ji)的(de)散(san)(san)熱，變(bian)壓(ya)器(qi)(qi)(qi)(qi)油(you)不能直(zhi)接安裝在(zai)上(shang)述位(wei)置，變(bian)壓(ya)器(qi)(qi)(qi)(qi)油(you)不能直(zhi)接安裝在(zai)上(shang)述位(wei)置，因(yin)為(wei)變(bian)壓(ya)器(qi)(qi)(qi)(qi)油(you)在(zai)事故工況或泄漏中的(de)燃(ran)燒風險。

　　干式變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)與油(you)(you)式變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)的(de)(de)(de)區(qu)別(bie)：油(you)(you)浸式變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)以油(you)(you)作為(wei)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)的(de)(de)(de)主要(yao)絕緣手段，利用油(you)(you)作為(wei)冷(leng)(leng)卻介(jie)質(自冷(leng)(leng))。風冷(leng)(leng)水(shui)冷(leng)(leng)一般升壓(ya)(ya)(ya)站的(de)(de)(de)主要(yao)變(bian)(bian)(bian)(bian)化都是油(you)(you)浸式的(de)(de)(de)，變(bian)(bian)(bian)(bian)化到20KV/500KV。干式變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)依靠空氣對流進(jin)行(xing)冷(leng)(leng)卻。小容量變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)變(bian)(bian)(bian)(bian)比6000V/400V。 干式變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)和油(you)(you)式變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)相(xiang)比，除工作原理(li)相(xiang)同外，最大的(de)(de)(de)區(qu)別(bie)就是變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)內部(bu)有沒有油(you)(you)，同時(shi)還(huan)有許多區(qu)別(bie)。
