山東聊城變壓器廠業內人士認為 整流變壓器廠家告訴你 gy額(e)(e)(e)定(ding)(ding)容(rong)量(liang)是(shi)指主分(fen)接(jie)下視在(zai)功率的(de)(de)慣用(yong)值。在(zai)變壓(ya)(ya)(ya)(ya)(ya)器(qi)銘(ming)牌上規定(ding)(ding)的(de)(de)容(rong)量(liang)就是(shi)額(e)(e)(e)定(ding)(ding)容(rong)量(liang)重大(da)遺(yi)漏，它(ta)是(shi)指分(fen)接(jie)開(kai)關位于(yu)(yu)主分(fen)接(jie)，是(shi)額(e)(e)(e)定(ding)(ding)空(kong)(kong)載(zai)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)、額(e)(e)(e)定(ding)(ding)電(dian)(dian)(dian)流(liu)(liu)與相(xiang)應的(de)(de)相(xiang)系數的(de)(de)乘(cheng)積。對三相(xiang)變壓(ya)(ya)(ya)(ya)(ya)器(qi)而言(yan)整(zheng)(zheng)流(liu)(liu)整(zheng)(zheng)流(liu)(liu)變壓(ya)(ya)(ya)(ya)(ya)器(qi)廠家，額(e)(e)(e)定(ding)(ding)容(rong)量(liang)等于(yu)(yu)=√3×額(e)(e)(e)定(ding)(ding)空(kong)(kong)載(zai)線電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)×額(e)(e)(e)定(ding)(ding)相(xiang)電(dian)(dian)(dian)流(liu)(liu)，額(e)(e)(e)定(ding)(ding)容(rong)量(liang)一般以(yi)kVA或MVA表示。額(e)(e)(e)定(ding)(ding)容(rong)量(liang)是(shi)在(zai)規定(ding)(ding)的(de)(de)整(zheng)(zheng)個正常(chang)使(shi)用(yong)壽(shou)命期間持續疲軟整(zheng)(zheng)流(liu)(liu)整(zheng)(zheng)流(liu)(liu)變壓(ya)(ya)(ya)(ya)(ya)器(qi)廠家，如(ru)30年，所能(neng)連(lian)續輸出最大(da)容(rong)量(liang)。而實際輸出容(rong)量(liang)為有負(fu)載(zai)時(shi)的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(感(gan)性負(fu)載(zai)時(shi)，負(fu)載(zai)時(shi)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)小于(yu)(yu)額(e)(e)(e)定(ding)(ding)空(kong)(kong)載(zai)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya))、額(e)(e)(e)定(ding)(ding)電(dian)(dian)(dian)流(liu)(liu)與相(xiang)應系數的(de)(de)乘(cheng)積。。
