干式變壓器和油浸式變壓器的區別

1、外觀

封裝形(xing)式(shi)不同，干式(shi)變壓(ya)器(qi)能直接看(kan)到鐵芯(xin)和線(xian)圈，而油式(shi)變壓(ya)器(qi)只能看(kan)到變壓(ya)器(qi)的外殼；

2、引線形式不同

干式變壓(ya)器(qi)大(da)多使用(yong)硅橡膠套(tao)管，而油式變壓(ya)器(qi)大(da)部分使用(yong)瓷套(tao)管；

3、容量及電壓不同

干式變壓(ya)(ya)(ya)(ya)器(qi)(qi)一般適用于(yu)配電(dian)(dian)用，容(rong)(rong)量大都(dou)在(zai)1600KVA以下，電(dian)(dian)壓(ya)(ya)(ya)(ya)在(zai)10KV以下，也有(you)個別做(zuo)到35KV電(dian)(dian)壓(ya)(ya)(ya)(ya)等(deng)級的(de)(de)(de)；而油式變壓(ya)(ya)(ya)(ya)器(qi)(qi)卻可以從小到大做(zuo)到全部容(rong)(rong)量，電(dian)(dian)壓(ya)(ya)(ya)(ya)等(deng)級也做(zuo)到了所有(you)電(dian)(dian)壓(ya)(ya)(ya)(ya)；我國正在(zai)建設的(de)(de)(de)特高(gao)壓(ya)(ya)(ya)(ya)1000KV試驗線(xian)路，采用的(de)(de)(de)一定是油式變壓(ya)(ya)(ya)(ya)器(qi)(qi)。

4、絕緣和散熱不一樣

干(gan)式變壓(ya)(ya)器(qi)一(yi)般用樹脂(zhi)絕緣，靠(kao)(kao)自(zi)然風冷，大容量靠(kao)(kao)風機冷卻，而油式變壓(ya)(ya)器(qi)靠(kao)(kao)絕緣油進行(xing)絕緣，靠(kao)(kao)絕緣油在變壓(ya)(ya)器(qi)內部的(de)(de)循(xun)環將線(xian)圈(quan)產生的(de)(de)熱(re)帶到變壓(ya)(ya)器(qi)的(de)(de)散熱(re)器(qi)（片）上進行(xing)散熱(re)。

5、適用場所

干式變(bian)壓器(qi)(qi)大多應(ying)用(yong)在(zai)需要“防火、防爆(bao)”的場所(suo)，一般大型建(jian)筑、高層建(jian)筑上易(yi)采用(yong)；而油式變(bian)壓器(qi)(qi)由于“出事”后可能(neng)有(you)(you)油噴出或泄漏，造成火災，大多應(ying)用(yong)在(zai)室外(wai)，且(qie)有(you)(you)場地挖(wa)設“事故油池”的場所(suo)。

6、對負荷的承受能力不同

一(yi)般干(gan)式(shi)變壓(ya)器(qi)應在額定(ding)容量下運行(xing)，而油式(shi)變壓(ya)器(qi)過載能力比較好。

7、造價不一樣

對同容量(liang)變(bian)壓器來說(shuo)，干(gan)式變(bian)壓器的采(cai)購價(jia)格比油式變(bian)壓器價(jia)格要(yao)高許多。

干(gan)式(shi)變壓器型號一般開頭為SC（環(huan)(huan)氧樹脂(zhi)澆注包封式(shi)）、SCR（非環(huan)(huan)氧樹脂(zhi)澆注固體(ti)絕緣(yuan)包封式(shi)）、SG（敞開式(shi)）

選擇干式變壓器還是油式變壓器？

價格上干(gan)變(bian)(bian)(bian)(bian)(bian)(bian)比油(you)變(bian)(bian)(bian)(bian)(bian)(bian)貴。容量上，大容量的(de)油(you)變(bian)(bian)(bian)(bian)(bian)(bian)比干(gan)變(bian)(bian)(bian)(bian)(bian)(bian)多。在(zai)綜合建筑(zhu)內（地(di)下(xia)室、樓層中、樓頂(ding)等）和人員密集場(chang)所(suo)需使(shi)用(yong)干(gan)變(bian)(bian)(bian)(bian)(bian)(bian)。油(you)變(bian)(bian)(bian)(bian)(bian)(bian)采(cai)用(yong)在(zai)獨立的(de)變(bian)(bian)(bian)(bian)(bian)(bian)電(dian)場(chang)所(suo)。箱變(bian)(bian)(bian)(bian)(bian)(bian)內變(bian)(bian)(bian)(bian)(bian)(bian)壓器一般(ban)采(cai)用(yong)箱變(bian)(bian)(bian)(bian)(bian)(bian)。戶外臨時(shi)(shi)用(yong)電(dian)一般(ban)采(cai)用(yong)油(you)變(bian)(bian)(bian)(bian)(bian)(bian)。在(zai)建設(she)時(shi)(shi)根據空(kong)(kong)間來選擇(ze)干(gan)變(bian)(bian)(bian)(bian)(bian)(bian)和油(you)變(bian)(bian)(bian)(bian)(bian)(bian)，空(kong)(kong)間較大時(shi)(shi)可以選擇(ze)油(you)變(bian)(bian)(bian)(bian)(bian)(bian)，空(kong)(kong)間較為擁擠時(shi)(shi)選擇(ze)干(gan)變(bian)(bian)(bian)(bian)(bian)(bian)。區(qu)域氣(qi)候(hou)比較潮濕悶(men)熱地(di)區(qu)，易使(shi)用(yong)油(you)變(bian)(bian)(bian)(bian)(bian)(bian)。如果使(shi)用(yong)干(gan)變(bian)(bian)(bian)(bian)(bian)(bian)的(de)情況(kuang)下(xia)，必(bi)須配有強制風冷設(she)備。
