【干式變(bian)(bian)壓(ya)(ya)器(qi) 油浸式變(bian)(bian)壓(ya)(ya)器(qi)】干式變(bian)(bian)壓(ya)(ya)器(qi)和(he)油浸式變(bian)(bian)壓(ya)(ya)器(qi)的區別

干式變壓器和油浸式變壓器的區別

1、外觀

封裝形式不(bu)同，干(gan)式變壓器能(neng)(neng)直接看到(dao)鐵芯和(he)線圈，而油(you)式變壓器只(zhi)能(neng)(neng)看到(dao)變壓器的(de)外殼；

2、引線形式不同

干式(shi)變壓器(qi)大多使用硅(gui)橡(xiang)膠(jiao)套管，而油式(shi)變壓器(qi)大部(bu)分使用瓷套管；

3、容量及電壓不同

干(gan)式變(bian)壓(ya)(ya)器一般適用于(yu)配電(dian)(dian)(dian)用，容量大(da)都在1600KVA以(yi)下，電(dian)(dian)(dian)壓(ya)(ya)在10KV以(yi)下，也有(you)個別做(zuo)到(dao)35KV電(dian)(dian)(dian)壓(ya)(ya)等(deng)級(ji)的；而油(you)式變(bian)壓(ya)(ya)器卻可以(yi)從(cong)小到(dao)大(da)做(zuo)到(dao)全(quan)部容量，電(dian)(dian)(dian)壓(ya)(ya)等(deng)級(ji)也做(zuo)到(dao)了所有(you)電(dian)(dian)(dian)壓(ya)(ya)；我(wo)國正在建設的特高壓(ya)(ya)1000KV試驗線路，采用的一定是油(you)式變(bian)壓(ya)(ya)器。

4、絕緣和散熱不一樣

干(gan)式(shi)變壓(ya)器(qi)一般用樹脂絕(jue)緣，靠自然風(feng)(feng)冷，大(da)容量(liang)靠風(feng)(feng)機(ji)冷卻，而油(you)(you)式(shi)變壓(ya)器(qi)靠絕(jue)緣油(you)(you)進(jin)行(xing)絕(jue)緣，靠絕(jue)緣油(you)(you)在(zai)變壓(ya)器(qi)內部的循(xun)環將線圈產(chan)生的熱(re)帶到(dao)變壓(ya)器(qi)的散熱(re)器(qi)（片）上(shang)進(jin)行(xing)散熱(re)。

5、適用場所

干式(shi)變(bian)(bian)壓(ya)器大多應(ying)用在需要“防火、防爆(bao)”的(de)場(chang)(chang)所，一(yi)般大型(xing)建筑(zhu)、高(gao)層建筑(zhu)上易采用；而油式(shi)變(bian)(bian)壓(ya)器由于“出事(shi)(shi)”后可能有(you)油噴(pen)出或泄(xie)漏，造成火災，大多應(ying)用在室外，且有(you)場(chang)(chang)地挖設“事(shi)(shi)故油池(chi)”的(de)場(chang)(chang)所。

6、對負荷的承受能力不同

一般干式(shi)變(bian)(bian)壓器應在額定容量下運行(xing)，而油式(shi)變(bian)(bian)壓器過載能力比較好。

7、造價不一樣

對同容(rong)量變壓器來說(shuo)，干式變壓器的(de)采購價格比油式變壓器價格要高(gao)許多。

干式(shi)(shi)變壓器(qi)型號一般(ban)開頭為SC（環(huan)氧樹脂(zhi)澆注(zhu)包封式(shi)(shi)）、SCR（非環(huan)氧樹脂(zhi)澆注(zhu)固體絕緣包封式(shi)(shi)）、SG（敞開式(shi)(shi)）

選擇干式變壓器還是油式變壓器？

價格上(shang)干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)比油(you)(you)變(bian)(bian)(bian)(bian)(bian)貴。容量上(shang)，大容量的(de)油(you)(you)變(bian)(bian)(bian)(bian)(bian)比干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)多(duo)。在綜合建筑(zhu)內（地下室、樓(lou)層中、樓(lou)頂等）和人員密集(ji)場所需使(shi)用干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)。油(you)(you)變(bian)(bian)(bian)(bian)(bian)采用在獨立的(de)變(bian)(bian)(bian)(bian)(bian)電場所。箱變(bian)(bian)(bian)(bian)(bian)內變(bian)(bian)(bian)(bian)(bian)壓器一般(ban)采用箱變(bian)(bian)(bian)(bian)(bian)。戶外(wai)臨時用電一般(ban)采用油(you)(you)變(bian)(bian)(bian)(bian)(bian)。在建設(she)時根據空(kong)間(jian)來(lai)選擇干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)和油(you)(you)變(bian)(bian)(bian)(bian)(bian)，空(kong)間(jian)較大時可(ke)以選擇油(you)(you)變(bian)(bian)(bian)(bian)(bian)，空(kong)間(jian)較為擁擠時選擇干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)。區域氣候比較潮濕悶(men)熱地區，易使(shi)用油(you)(you)變(bian)(bian)(bian)(bian)(bian)。如果使(shi)用干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)的(de)情況(kuang)下，必須配有(you)強制風冷設(she)備。
