干式變壓器和油浸式變壓器的區別

1、外觀

封裝(zhuang)形式不同，干式變壓(ya)器(qi)能直(zhi)接看(kan)到(dao)鐵(tie)芯和線圈，而油式變壓(ya)器(qi)只能看(kan)到(dao)變壓(ya)器(qi)的外殼；

2、引線形式不同

干(gan)式(shi)變壓(ya)器(qi)大(da)多使(shi)用硅橡膠套管，而(er)油式(shi)變壓(ya)器(qi)大(da)部分(fen)使(shi)用瓷套管；

3、容量及電壓不同

干式(shi)變(bian)壓器(qi)一(yi)般(ban)適用于配電(dian)用，容(rong)量大都在(zai)1600KVA以下，電(dian)壓在(zai)10KV以下，也有個別(bie)做到(dao)35KV電(dian)壓等級(ji)的(de)；而油(you)式(shi)變(bian)壓器(qi)卻(que)可以從小到(dao)大做到(dao)全部容(rong)量，電(dian)壓等級(ji)也做到(dao)了所有電(dian)壓；我國正在(zai)建設(she)的(de)特高壓1000KV試(shi)驗線路，采用的(de)一(yi)定(ding)是油(you)式(shi)變(bian)壓器(qi)。

4、絕緣和散熱不一樣

干(gan)式變壓(ya)器(qi)(qi)一般(ban)用樹脂(zhi)絕緣，靠自然風冷，大容量靠風機冷卻，而油式變壓(ya)器(qi)(qi)靠絕緣油進行(xing)絕緣，靠絕緣油在變壓(ya)器(qi)(qi)內部的(de)循環將線圈(quan)產生的(de)熱(re)帶到(dao)變壓(ya)器(qi)(qi)的(de)散熱(re)器(qi)(qi)（片）上進行(xing)散熱(re)。

5、適用場所

干式(shi)(shi)變壓(ya)器(qi)大(da)多應(ying)用在需(xu)要“防火、防爆(bao)”的場所，一般大(da)型建(jian)筑、高(gao)層建(jian)筑上易采用；而油式(shi)(shi)變壓(ya)器(qi)由于“出(chu)事(shi)”后可能有(you)油噴出(chu)或(huo)泄漏，造成火災，大(da)多應(ying)用在室外，且有(you)場地挖設“事(shi)故油池”的場所。

6、對負荷的承受能力不同

一般干式(shi)變壓(ya)器(qi)應在(zai)額(e)定容量(liang)下運行(xing)，而油式(shi)變壓(ya)器(qi)過載能力(li)比較(jiao)好(hao)。

7、造價不一樣

對同容量變壓器來說(shuo)，干式(shi)變壓器的采購價格比油式(shi)變壓器價格要高許多。

干式變壓器型號一般(ban)開頭為SC（環氧(yang)樹(shu)脂澆(jiao)注包封式）、SCR（非環氧(yang)樹(shu)脂澆(jiao)注固(gu)體絕緣(yuan)包封式）、SG（敞開式）

選擇干式變壓器還是油式變壓器？

價格上干(gan)(gan)變(bian)(bian)(bian)(bian)比油(you)變(bian)(bian)(bian)(bian)貴。容量上，大(da)(da)容量的(de)油(you)變(bian)(bian)(bian)(bian)比干(gan)(gan)變(bian)(bian)(bian)(bian)多。在綜合建筑(zhu)內（地(di)下室、樓層中、樓頂等）和人員密集(ji)場所需(xu)使用(yong)(yong)(yong)干(gan)(gan)變(bian)(bian)(bian)(bian)。油(you)變(bian)(bian)(bian)(bian)采(cai)(cai)用(yong)(yong)(yong)在獨立的(de)變(bian)(bian)(bian)(bian)電場所。箱變(bian)(bian)(bian)(bian)內變(bian)(bian)(bian)(bian)壓器一般采(cai)(cai)用(yong)(yong)(yong)箱變(bian)(bian)(bian)(bian)。戶外(wai)臨時(shi)用(yong)(yong)(yong)電一般采(cai)(cai)用(yong)(yong)(yong)油(you)變(bian)(bian)(bian)(bian)。在建設時(shi)根據(ju)空間(jian)(jian)來選擇(ze)干(gan)(gan)變(bian)(bian)(bian)(bian)和油(you)變(bian)(bian)(bian)(bian)，空間(jian)(jian)較(jiao)大(da)(da)時(shi)可以選擇(ze)油(you)變(bian)(bian)(bian)(bian)，空間(jian)(jian)較(jiao)為擁擠時(shi)選擇(ze)干(gan)(gan)變(bian)(bian)(bian)(bian)。區域氣候比較(jiao)潮濕悶熱(re)地(di)區，易使用(yong)(yong)(yong)油(you)變(bian)(bian)(bian)(bian)。如果使用(yong)(yong)(yong)干(gan)(gan)變(bian)(bian)(bian)(bian)的(de)情況下，必須配有強制風冷設備。
