SCB14-800KVA干式變壓器

　　一般(ban)認為(wei)SCB14-800KVA干(gan)式(shi)變(bian)壓(ya)器(qi)(qi)在(zai)正常運(yun)行中達到(dao)95℃的(de)(de)(de)溫(wen)(wen)(wen)度(du)(du)(du)較高(gao)(gao)。我們不能再增加負荷了。低(di)壓(ya)機械設備一般(ban)要(yao)求溫(wen)(wen)(wen)升(sheng)(sheng)不超過60度(du)(du)(du)(即工(gong)作溫(wen)(wen)(wen)度(du)(du)(du)+60度(du)(du)(du))。過高(gao)(gao)的(de)(de)(de)溫(wen)(wen)(wen)度(du)(du)(du)會加速機械設備絕(jue)(jue)緣(yuan)(yuan)層(ceng)(ceng)的(de)(de)(de)老化(hua)，縮短其(qi)使(shi)用(yong)壽(shou)命。125K限值(zhi)為(wei)H級(ji)絕(jue)(jue)緣(yuan)(yuan)層(ceng)(ceng)，國家(jia)行業(ye)標準《SCB14-800KVA干(gan)式(shi)變(bian)壓(ya)器(qi)(qi)》GB6450-1986對SCB14-800KVA干(gan)式(shi)變(bian)壓(ya)器(qi)(qi)溫(wen)(wen)(wen)升(sheng)(sheng)限提(ti)出了要(yao)求。1.SCB14-800KVA干(gan)式(shi)變(bian)壓(ya)器(qi)(qi)的(de)(de)(de)電磁線圈，使(shi)用(yong)a級(ji)絕(jue)(jue)緣(yuan)(yuan)層(ceng)(ceng)材(cai)(cai)料(liao)時(shi)(shi)，其(qi)高(gao)(gao)工(gong)作溫(wen)(wen)(wen)度(du)(du)(du)應(ying)為(wei)105℃，高(gao)(gao)溫(wen)(wen)(wen)上升(sheng)(sheng)應(ying)小(xiao)于(yu)60K，選(xuan)(xuan)擇(ze)電子(zi)級(ji)保(bao)溫(wen)(wen)(wen)層(ceng)(ceng)材(cai)(cai)料(liao)時(shi)(shi)，120℃時(shi)(shi)的(de)(de)(de)高(gao)(gao)工(gong)作溫(wen)(wen)(wen)度(du)(du)(du)應(ying)小(xiao)于(yu)75K。選(xuan)(xuan)擇(ze)B級(ji)保(bao)溫(wen)(wen)(wen)層(ceng)(ceng)材(cai)(cai)料(liao)時(shi)(shi)，溫(wen)(wen)(wen)度(du)(du)(du)升(sheng)(sheng)高(gao)(gao)130℃時(shi)(shi)，高(gao)(gao)工(gong)作溫(wen)(wen)(wen)度(du)(du)(du)應(ying)在(zai)80K以下(xia)。使(shi)用(yong)F級(ji)絕(jue)(jue)緣(yuan)(yuan)層(ceng)(ceng)材(cai)(cai)料(liao)時(shi)(shi)，155℃下(xia)的(de)(de)(de)高(gao)(gao)工(gong)作溫(wen)(wen)(wen)度(du)(du)(du)應(ying)小(xiao)于(yu)100K，使(shi)用(yong)H級(ji)絕(jue)(jue)緣(yuan)(yuan)層(ceng)(ceng)材(cai)(cai)料(liao)時(shi)(shi)，180℃下(xia)的(de)(de)(de)高(gao)(gao)工(gong)作溫(wen)(wen)(wen)度(du)(du)(du)應(ying)小(xiao)于(yu)125K，選(xuan)(xuan)擇(ze)C級(ji)絕(jue)(jue)緣(yuan)(yuan)層(ceng)(ceng)材(cai)(cai)料(liao)時(shi)(shi)，220℃下(xia)的(de)(de)(de)高(gao)(gao)工(gong)作溫(wen)(wen)(wen)度(du)(du)(du)應(ying)小(xiao)于(yu)150K。

　　目(mu)前大多數SCB14-800KVA干(gan)式變壓器都使用H級絕緣層(ceng)材料，因此SCB14-800KVA干(gan)式變壓器的環境溫(wen)度一般應在180℃以下。

　　因此，95度(du)的工作溫度(du)是安(an)全(quan)可靠(kao)的。安(an)裝(zhuang)方便，不影響布線!電氣設備(bei)之間的距離相當大!可以降低鐵格(ge)子的高(gao)度(du)!減少核心使(shi)用
