為(wei)更新(xin)觀念，引進新(xin)科技，8月(yue)(yue)份，鉛(qian)鋅事(shi)業部在盧(lu)均勝副總的(de)指導下，召(zhao)集(ji)事(shi)業部相(xiang)關技術(shu)人員(yuan)，探(tan)討改(gai)裝高(gao)壓(ya)電(dian)動機(ji)的(de)啟動運行(xing)方(fang)式，以(yi)達到(dao)節能環保的(de)目的(de)。經(jing)過多方(fang)考察、請教，不斷論證，采購的(de)4臺高(gao)壓(ya)變(bian)頻(pin)器(qi)10月(yue)(yue)到(dao)貨。鉛(qian)鋅事(shi)業部機(ji)電(dian)班(ban)利(li)用(yong)11月(yue)(yue)、12月(yue)(yue)的(de)檢(jian)修時間，將4臺高(gao)壓(ya)變(bian)頻(pin)器(qi)全部安裝到(dao)位并投入運行(xing)。    

      目(mu)前(qian)4臺高(gao)(gao)壓(ya)(ya)(ya)變頻(pin)器總體運(yun)行效(xiao)果良(liang)好。主要體現在兩個方(fang)面(mian)。一(yi)是(shi)高(gao)(gao)壓(ya)(ya)(ya)變頻(pin)器投(tou)入(ru)前(qian)，鉛鋅事業部(bu)的(de)高(gao)(gao)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)全(quan)部(bu)是(shi)直接啟動(dong)(dong)，啟動(dong)(dong)過(guo)程中(zhong)，大(da)量吸(xi)收電(dian)(dian)(dian)(dian)網(wang)(wang)無功功率來(lai)建(jian)立(li)磁場，從而造(zao)成(cheng)(cheng)(cheng)電(dian)(dian)(dian)(dian)網(wang)(wang)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)降(jiang)(jiang)低。運(yun)行電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)由10.3KV左右降(jiang)(jiang)至9KV左右。如果電(dian)(dian)(dian)(dian)網(wang)(wang)中(zhong)此時(shi)啟動(dong)(dong)大(da)功率設(she)備，將造(zao)成(cheng)(cheng)(cheng)設(she)備因(yin)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過(guo)低而停止運(yun)行，影響生產。改裝后高(gao)(gao)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)啟動(dong)(dong)方(fang)式，彌補了因(yin)大(da)功率設(she)備啟動(dong)(dong)而造(zao)成(cheng)(cheng)(cheng)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)降(jiang)(jiang)低這一(yi)缺點(dian)。高(gao)(gao)壓(ya)(ya)(ya)變頻(pin)調速(su)系(xi)統用的(de)是(shi)功率單元(yuan)串聯的(de)方(fang)案，用多繞組高(gao)(gao)壓(ya)(ya)(ya)移相(xiang)變壓(ya)(ya)(ya)器，完全(quan)滿足了設(she)備對電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)流諧波(bo)含量的(de)要求。高(gao)(gao)壓(ya)(ya)(ya)變頻(pin)器在電(dian)(dian)(dian)(dian)網(wang)(wang)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)-15%～+15%范圍內，仍然(ran)正常工(gong)作，并(bing)根據運(yun)行工(gong)控參(can)數的(de)實際情況(kuang)，自(zi)動(dong)(dong)調整(zheng)加減速(su)時(shi)間，從而平滑啟動(dong)(dong)，解決了因(yin)啟動(dong)(dong)大(da)功率設(she)備而造(zao)成(cheng)(cheng)(cheng)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)降(jiang)(jiang)低這一(yi)難題。

      另一(yi)方(fang)面改變(bian)(bian)了設(she)備(bei)的(de)(de)(de)調整方(fang)式。原來(lai)(lai)風(feng)機(ji)(ji)(ji)(ji)都是調整風(feng)機(ji)(ji)(ji)(ji)閥門的(de)(de)(de)開度(du)來(lai)(lai)調整風(feng)量(liang)，滿足(zu)運行條件的(de)(de)(de)需求(qiu)(qiu)，但電(dian)(dian)機(ji)(ji)(ji)(ji)總體出力沒變(bian)(bian)。改裝后的(de)(de)(de)高(gao)壓電(dian)(dian)機(ji)(ji)(ji)(ji)通過調頻而調速，控制電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)(de)轉(zhuan)速，來(lai)(lai)調整風(feng)機(ji)(ji)(ji)(ji)風(feng)量(liang)。這(zhe)一(yi)改變(bian)(bian)，大大降(jiang)低(di)了用(yong)電(dian)(dian)量(liang)，預計這(zhe)4臺(tai)高(gao)壓變(bian)(bian)頻器每月將節約40萬KWH左右。以(yi)前一(yi)臺(tai)額定功率(lv)630KW的(de)(de)(de)風(feng)機(ji)(ji)(ji)(ji)，在出力相同的(de)(de)(de)情況(kuang)下，工頻運行達到450KW，變(bian)(bian)頻運行后達到200KW，即可滿足(zu)風(feng)量(liang)的(de)(de)(de)要(yao)求(qiu)(qiu)。由于風(feng)機(ji)(ji)(ji)(ji)的(de)(de)(de)轉(zhuan)速降(jiang)低(di)，風(feng)機(ji)(ji)(ji)(ji)運行時的(de)(de)(de)噪(zao)音也基本消失。

      這一項目的(de)(de)(de)成功投運，只是公司節能降耗改革方面的(de)(de)(de)一個縮影。相(xiang)信在(zai)集(ji)團(tuan)公司領導的(de)(de)(de)決策下，在(zai)廣大干部(bu)職工(gong)的(de)(de)(de)團(tuan)結下，萬洋集(ji)團(tuan)這艘大船將乘風破浪，永(yong)不退縮，抵達新(xin)的(de)(de)(de)彼岸。
