【干式(shi)變(bian)壓器(qi)(qi) 油浸式(shi)變(bian)壓器(qi)(qi)】干式(shi)變(bian)壓器(qi)(qi)和油浸式(shi)變(bian)壓器(qi)(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(shi)不(bu)同(tong),干式(shi)變(bian)(bian)壓(ya)器能直接看到鐵(tie)芯和(he)線圈,而油(you)式(shi)變(bian)(bian)壓(ya)器只能看到變(bian)(bian)壓(ya)器的外殼(ke);
2、引線形式不同
干式(shi)(shi)變(bian)壓(ya)器大(da)多(duo)使(shi)用硅橡膠(jiao)套管,而(er)油式(shi)(shi)變(bian)壓(ya)器大(da)部分使(shi)用瓷(ci)套管;
3、容量及電壓不同
干式變壓(ya)(ya)(ya)器一般適用(yong)于配電(dian)(dian)(dian)用(yong),容量大都(dou)在1600KVA以下(xia),電(dian)(dian)(dian)壓(ya)(ya)(ya)在10KV以下(xia),也有(you)個別做(zuo)到35KV電(dian)(dian)(dian)壓(ya)(ya)(ya)等級(ji)的(de);而油式變壓(ya)(ya)(ya)器卻可以從小到大做(zuo)到全部容量,電(dian)(dian)(dian)壓(ya)(ya)(ya)等級(ji)也做(zuo)到了所有(you)電(dian)(dian)(dian)壓(ya)(ya)(ya);我國(guo)正在建設(she)的(de)特(te)高壓(ya)(ya)(ya)1000KV試驗線路,采用(yong)的(de)一定是油式變壓(ya)(ya)(ya)器。
4、絕緣和散熱不一樣
干式變壓器(qi)一般(ban)用樹脂(zhi)絕緣,靠(kao)自然風冷,大容量(liang)靠(kao)風機(ji)冷卻,而油式變壓器(qi)靠(kao)絕緣油進行絕緣,靠(kao)絕緣油在變壓器(qi)內(nei)部的(de)循環(huan)將線圈產生的(de)熱(re)帶到變壓器(qi)的(de)散熱(re)器(qi)(片)上進行散熱(re)。
5、適用場所
干式(shi)變(bian)壓(ya)器(qi)大(da)多(duo)應(ying)用在需要“防(fang)火、防(fang)爆”的場所(suo),一般大(da)型建筑、高(gao)層建筑上易采(cai)用;而油式(shi)變(bian)壓(ya)器(qi)由于“出事”后(hou)可能(neng)有油噴出或泄(xie)漏,造成火災,大(da)多(duo)應(ying)用在室外,且(qie)有場地挖設“事故油池”的場所(suo)。
6、對負荷的承受能力不同
一般(ban)干式變(bian)壓器(qi)應在額定(ding)容量下運行,而油式變(bian)壓器(qi)過載能力比較好。
7、造價不一樣
對同容量(liang)變壓器來說,干式(shi)變壓器的采(cai)購(gou)價(jia)格比油(you)式(shi)變壓器價(jia)格要高許(xu)多。
干式(shi)變壓(ya)器型號一般開(kai)頭為(wei)SC(環氧樹(shu)脂(zhi)澆注包封式(shi))、SCR(非環氧樹(shu)脂(zhi)澆注固體絕緣包封式(shi))、SG(敞開(kai)式(shi))
選擇干式變壓器還是油式變壓器?
價格上(shang)(shang)干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)比(bi)油(you)(you)(you)(you)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)貴。容量上(shang)(shang),大容量的(de)油(you)(you)(you)(you)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)比(bi)干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)多。在綜(zong)合(he)建筑(zhu)內(nei)(地下室、樓層中、樓頂等)和人(ren)員密集(ji)場所需使用(yong)(yong)(yong)干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)。油(you)(you)(you)(you)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)采(cai)(cai)用(yong)(yong)(yong)在獨立的(de)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)電(dian)場所。箱變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)內(nei)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)壓(ya)器一(yi)般采(cai)(cai)用(yong)(yong)(yong)箱變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)。戶外臨時用(yong)(yong)(yong)電(dian)一(yi)般采(cai)(cai)用(yong)(yong)(yong)油(you)(you)(you)(you)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)。在建設時根據(ju)空(kong)(kong)間(jian)來選擇干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)和油(you)(you)(you)(you)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian),空(kong)(kong)間(jian)較大時可以選擇油(you)(you)(you)(you)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian),空(kong)(kong)間(jian)較為擁擠(ji)時選擇干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)。區(qu)(qu)域(yu)氣候比(bi)較潮(chao)濕悶熱地區(qu)(qu),易使用(yong)(yong)(yong)油(you)(you)(you)(you)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)。如果使用(yong)(yong)(yong)干(gan)(gan)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)(bian)的(de)情況下,必須配(pei)有強制風冷設備。
