35KV干式變壓器廠家解析干(gan)式變壓器的溫度在不能(neng)超(chao)過多(duo)少(shao)度

1、國家標準《干式(shi)(shi)變壓(ya)器》GB6450-1986對干式(shi)(shi)變壓(ya)器的溫(wen)(wen)(wen)(wen)升(sheng)(sheng)限(xian)值做出了規(gui)定。1、對干式(shi)(shi)變壓(ya)器的線圈，當采(cai)用A級(ji)(ji)絕(jue)(jue)(jue)(jue)緣(yuan)材(cai)(cai)(cai)(cai)(cai)料(liao)時(shi)，其(qi)(qi)(qi)極(ji)(ji)限(xian)工(gong)作溫(wen)(wen)(wen)(wen)度(du)在(zai)105℃時(shi)，最(zui)(zui)高(gao)溫(wen)(wen)(wen)(wen)升(sheng)(sheng)應小于(yu)(yu)60K；當采(cai)用E級(ji)(ji)絕(jue)(jue)(jue)(jue)緣(yuan)材(cai)(cai)(cai)(cai)(cai)料(liao)時(shi)，其(qi)(qi)(qi)極(ji)(ji)限(xian)工(gong)作溫(wen)(wen)(wen)(wen)度(du)在(zai)120℃時(shi)，最(zui)(zui)高(gao)溫(wen)(wen)(wen)(wen)升(sheng)(sheng)應小于(yu)(yu)75K；當采(cai)用B級(ji)(ji)絕(jue)(jue)(jue)(jue)緣(yuan)材(cai)(cai)(cai)(cai)(cai)料(liao)時(shi)，其(qi)(qi)(qi)極(ji)(ji)限(xian)工(gong)作溫(wen)(wen)(wen)(wen)度(du)在(zai)130℃時(shi)，最(zui)(zui)高(gao)溫(wen)(wen)(wen)(wen)升(sheng)(sheng)應小于(yu)(yu)80K；當采(cai)用F級(ji)(ji)絕(jue)(jue)(jue)(jue)緣(yuan)材(cai)(cai)(cai)(cai)(cai)料(liao)時(shi)，其(qi)(qi)(qi)極(ji)(ji)限(xian)工(gong)作溫(wen)(wen)(wen)(wen)度(du)在(zai)155℃時(shi)，最(zui)(zui)高(gao)溫(wen)(wen)(wen)(wen)升(sheng)(sheng)應小于(yu)(yu)100K；當采(cai)用H級(ji)(ji)絕(jue)(jue)(jue)(jue)緣(yuan)材(cai)(cai)(cai)(cai)(cai)料(liao)時(shi)，其(qi)(qi)(qi)極(ji)(ji)限(xian)工(gong)作溫(wen)(wen)(wen)(wen)度(du)在(zai)180℃時(shi)，最(zui)(zui)高(gao)溫(wen)(wen)(wen)(wen)升(sheng)(sheng)應小于(yu)(yu)125K；當采(cai)用C級(ji)(ji)絕(jue)(jue)(jue)(jue)緣(yuan)材(cai)(cai)(cai)(cai)(cai)料(liao)時(shi)，其(qi)(qi)(qi)極(ji)(ji)限(xian)工(gong)作溫(wen)(wen)(wen)(wen)度(du)在(zai)220℃時(shi)，最(zui)(zui)高(gao)溫(wen)(wen)(wen)(wen)升(sheng)(sheng)應小于(yu)(yu)150K。

2、鐵芯(xin)、金(jin)屬部(bu)件和與其相鄰(lin)(lin)的(de)材(cai)料，在(zai)任(ren)何情況下，不會出現使鐵芯(xin)本身、其他部(bu)件或與其相鄰(lin)(lin)的(de)材(cai)料受(shou)到損害的(de)溫度。

現在大多數干式變壓器都采用H級絕緣材料，故一般說干式變壓器的溫度應在180℃以下。
