【干式(shi)變(bian)壓(ya)器(qi) 油浸(jin)式(shi)變(bian)壓(ya)器(qi)】干式(shi)變(bian)壓(ya)器(qi)和油浸(jin)式(shi)變(bian)壓(ya)器(qi)的區別(bie)

干式變壓器和油浸式變壓器的區別

1、外觀

封(feng)裝(zhuang)形式(shi)不(bu)同(tong)，干式(shi)變(bian)壓器(qi)能直(zhi)接看到鐵(tie)芯(xin)和線圈，而油(you)式(shi)變(bian)壓器(qi)只能看到變(bian)壓器(qi)的外殼；

2、引線形式不同

干(gan)式(shi)變(bian)壓器(qi)(qi)大多(duo)使用(yong)(yong)硅橡(xiang)膠套管，而(er)油(you)式(shi)變(bian)壓器(qi)(qi)大部分使用(yong)(yong)瓷套管；

3、容量及電壓不同

干(gan)式變壓(ya)(ya)(ya)(ya)器一(yi)般(ban)適(shi)用(yong)(yong)于配電用(yong)(yong)，容量(liang)大都在1600KVA以(yi)下(xia)，電壓(ya)(ya)(ya)(ya)在10KV以(yi)下(xia)，也有個別做(zuo)到(dao)35KV電壓(ya)(ya)(ya)(ya)等級(ji)的；而油式變壓(ya)(ya)(ya)(ya)器卻可以(yi)從小(xiao)到(dao)大做(zuo)到(dao)全部容量(liang)，電壓(ya)(ya)(ya)(ya)等級(ji)也做(zuo)到(dao)了所(suo)有電壓(ya)(ya)(ya)(ya)；我國正在建設的特高壓(ya)(ya)(ya)(ya)1000KV試驗(yan)線(xian)路，采用(yong)(yong)的一(yi)定是油式變壓(ya)(ya)(ya)(ya)器。

4、絕緣和散熱不一樣

干式變壓器一般用樹脂絕(jue)緣，靠(kao)自然風冷，大容量靠(kao)風機(ji)冷卻，而(er)油式變壓器靠(kao)絕(jue)緣油進(jin)行絕(jue)緣，靠(kao)絕(jue)緣油在變壓器內部的循環將線(xian)圈產生(sheng)的熱(re)帶到變壓器的散(san)熱(re)器（片）上進(jin)行散(san)熱(re)。

5、適用場所

干式變壓器(qi)大(da)(da)多(duo)應(ying)用在需要“防火、防爆”的(de)場所，一(yi)般大(da)(da)型建(jian)筑(zhu)、高層建(jian)筑(zhu)上(shang)易采(cai)用；而油(you)式變壓器(qi)由于“出(chu)事(shi)”后可能有油(you)噴出(chu)或(huo)泄漏(lou)，造(zao)成火災(zai)，大(da)(da)多(duo)應(ying)用在室外(wai)，且有場地挖設“事(shi)故油(you)池”的(de)場所。

6、對負荷的承受能力不同

一(yi)般干式變(bian)壓器應在額定容(rong)量(liang)下運行，而(er)油式變(bian)壓器過載能力比(bi)較好。

7、造價不一樣

對同容(rong)量變(bian)(bian)壓器(qi)來說(shuo)，干式(shi)變(bian)(bian)壓器(qi)的采(cai)購價格比油式(shi)變(bian)(bian)壓器(qi)價格要(yao)高許多(duo)。

干式(shi)變壓器型號一般開頭(tou)為SC（環(huan)氧(yang)樹脂(zhi)澆注包封式(shi)）、SCR（非環(huan)氧(yang)樹脂(zhi)澆注固體絕(jue)緣包封式(shi)）、SG（敞開式(shi)）

選擇干式變壓器還是油式變壓器？

價格上(shang)干變(bian)(bian)(bian)(bian)比油(you)變(bian)(bian)(bian)(bian)貴。容量(liang)上(shang)，大容量(liang)的(de)油(you)變(bian)(bian)(bian)(bian)比干變(bian)(bian)(bian)(bian)多。在(zai)綜合建(jian)筑(zhu)內（地下室、樓層中、樓頂等）和(he)人員密集場(chang)所需使(shi)用(yong)干變(bian)(bian)(bian)(bian)。油(you)變(bian)(bian)(bian)(bian)采用(yong)在(zai)獨立(li)的(de)變(bian)(bian)(bian)(bian)電(dian)場(chang)所。箱變(bian)(bian)(bian)(bian)內變(bian)(bian)(bian)(bian)壓(ya)器一般采用(yong)箱變(bian)(bian)(bian)(bian)。戶外(wai)臨(lin)時(shi)用(yong)電(dian)一般采用(yong)油(you)變(bian)(bian)(bian)(bian)。在(zai)建(jian)設時(shi)根據(ju)空(kong)(kong)間(jian)來選擇干變(bian)(bian)(bian)(bian)和(he)油(you)變(bian)(bian)(bian)(bian)，空(kong)(kong)間(jian)較大時(shi)可(ke)以(yi)選擇油(you)變(bian)(bian)(bian)(bian)，空(kong)(kong)間(jian)較為擁擠時(shi)選擇干變(bian)(bian)(bian)(bian)。區域氣(qi)候比較潮濕悶(men)熱地區，易使(shi)用(yong)油(you)變(bian)(bian)(bian)(bian)。如果使(shi)用(yong)干變(bian)(bian)(bian)(bian)的(de)情況下，必須配有強制風冷(leng)設備。
