產品特性
HDG系列硅鉬棒變壓器是我公司(si)根(gen)據市場需(xu)求，在(zai)低(di)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)大(da)電(dian)(dian)(dian)(dian)流變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的(de)(de)(de)基礎上研制而(er)成的(de)(de)(de)一種(zhong)干式電(dian)(dian)(dian)(dian)爐加熱(re)專用(yong)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)。硅(gui)鉬棒電(dian)(dian)(dian)(dian)熱(re)體(ti)(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)阻(zu)隨溫(wen)度升高急劇增大(da)，開始加熱(re)時，電(dian)(dian)(dian)(dian)熱(re)體(ti)(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)阻(zu)較小，所需(xu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)較低(di)，約為工作電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)(de)l/ 4—1/3，根(gen)據硅(gui)鉬棒電(dian)(dian)(dian)(dian)熱(re)體(ti)(ti)的(de)(de)(de)工作電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)及其電(dian)(dian)(dian)(dian)阻(zu)和(he)溫(wen)度的(de)(de)(de)正向特性，變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)輸出電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)采(cai)用(yong)多抽頭的(de)(de)(de)方式來滿足加熱(re)體(ti)(ti)在(zai)不同(tong)溫(wen)度時需(xu)要的(de)(de)(de)工作電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，從(cong)而(er)提高電(dian)(dian)(dian)(dian)網功率因數。由于需(xu)要在(zai)高溫(wen)的(de)(de)(de)環境里面連續工作，對變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的(de)(de)(de)性能(neng)提出了更高的(de)(de)(de)要求，本公司(si)生產的(de)(de)(de)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)鐵芯采(cai)用(yong)冷(leng)軋取(qu)向優(you)質硅(gui)鋼片(pian)迭積而(er)成，繞(rao)組初級(ji)(ji)采(cai)用(yong)H級(ji)(ji)耐高溫(wen)絕緣(yuan)雙層(ceng)玻(bo)璃絲包銅線繞(rao)制，次(ci)級(ji)(ji)繞(rao)組則采(cai)用(yong)裸銅排加工而(er)成。初次(ci)級(ji)(ji)留有通(tong)風道，保證了變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的(de)(de)(de)良好散熱(re)。產品符合GB19212-1991大(da)陸標準。
