產品特性
HDG系列硅鉬棒變壓器是我公司根據(ju)市場需(xu)(xu)求，在(zai)低電(dian)(dian)(dian)壓大(da)電(dian)(dian)(dian)流變(bian)壓器(qi)的(de)(de)(de)基礎上研制而(er)成的(de)(de)(de)一(yi)種干式電(dian)(dian)(dian)爐加(jia)熱(re)(re)(re)專用(yong)變(bian)壓器(qi)。硅(gui)鉬棒電(dian)(dian)(dian)熱(re)(re)(re)體的(de)(de)(de)電(dian)(dian)(dian)阻隨溫度(du)升(sheng)高(gao)(gao)急劇增大(da)，開始(shi)加(jia)熱(re)(re)(re)時，電(dian)(dian)(dian)熱(re)(re)(re)體的(de)(de)(de)電(dian)(dian)(dian)阻較(jiao)小，所需(xu)(xu)電(dian)(dian)(dian)壓較(jiao)低，約為工(gong)(gong)作(zuo)電(dian)(dian)(dian)壓的(de)(de)(de)l/ 4—1/3，根據(ju)硅(gui)鉬棒電(dian)(dian)(dian)熱(re)(re)(re)體的(de)(de)(de)工(gong)(gong)作(zuo)電(dian)(dian)(dian)壓及其電(dian)(dian)(dian)阻和溫度(du)的(de)(de)(de)正向特性，變(bian)壓器(qi)輸出電(dian)(dian)(dian)壓采(cai)(cai)用(yong)多抽頭的(de)(de)(de)方式來滿足加(jia)熱(re)(re)(re)體在(zai)不(bu)同溫度(du)時需(xu)(xu)要的(de)(de)(de)工(gong)(gong)作(zuo)電(dian)(dian)(dian)壓，從而(er)提高(gao)(gao)電(dian)(dian)(dian)網功(gong)率因數。由于需(xu)(xu)要在(zai)高(gao)(gao)溫的(de)(de)(de)環境里面連續(xu)工(gong)(gong)作(zuo)，對變(bian)壓器(qi)的(de)(de)(de)性能(neng)提出了(le)更(geng)高(gao)(gao)的(de)(de)(de)要求，本公司生(sheng)產(chan)(chan)的(de)(de)(de)變(bian)壓器(qi)鐵芯采(cai)(cai)用(yong)冷軋取向優質硅(gui)鋼片迭積而(er)成，繞(rao)組初級采(cai)(cai)用(yong)H級耐高(gao)(gao)溫絕(jue)緣雙層玻璃(li)絲(si)包銅(tong)線繞(rao)制，次級繞(rao)組則采(cai)(cai)用(yong)裸(luo)銅(tong)排加(jia)工(gong)(gong)而(er)成。初次級留(liu)有通風道，保證了(le)變(bian)壓器(qi)的(de)(de)(de)良好散熱(re)(re)(re)。產(chan)(chan)品符合GB19212-1991大(da)陸標準(zhun)。
