12月8日(ri)，江(jiang)蘇無錫(xi)市區(qu)首座(zuo)20千伏(fu)電(dian)(dian)壓(ya)線路供電(dian)(dian)110千伏(fu)雙廟變電(dian)(dian)站成功(gong)投運，為(wei)無錫(xi)年內9座(zuo)20千伏(fu)變電(dian)(dian)站密(mi)集投入運行拉開了序幕。
至(zhi)此，無錫(xi)供電公(gong)司(si)管(guan)轄的城區(qu)110千伏及(ji)以下的變電站將(jiang)迅(xun)速增至(zhi)111座(zuo)。在黨中央(yang)、國務院(yuan)提出擴大內需的一(yi)系列政(zheng)策后，該(gai)公(gong)司(si)深入生(sheng)產企(qi)業，了解到(dao)企(qi)業積(ji)極(ji)擴大生(sheng)產的情況，加快電網建(jian)設步伐，把計劃于(yu)明年(nian)投運的一(yi)些電網建(jian)設項目，提前(qian)到(dao)今年(nian)年(nian)底前(qian)竣工，以滿足企(qi)業發(fa)展(zhan)用電。
據了解，110千伏等(deng)級及以下變(bian)電(dian)(dian)(dian)(dian)(dian)站一般采(cai)(cai)用傳統(tong)的(de)(de)(de)10千伏電(dian)(dian)(dian)(dian)(dian)壓等(deng)級供電(dian)(dian)(dian)(dian)(dian)方式。20千伏供電(dian)(dian)(dian)(dian)(dian)與(yu)10千伏、35千伏配電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓等(deng)級相(xiang)比，供電(dian)(dian)(dian)(dian)(dian)容量(liang)大(da)、損(sun)耗小，電(dian)(dian)(dian)(dian)(dian)能(neng)質(zhi)量(liang)高，可節(jie)約社會投資、減少資源占用，具(ju)有顯著(zhu)的(de)(de)(de)技術經(jing)濟優勢(shi)，符合(he)資源節(jie)約型、環(huan)境友好(hao)型要求。目前，無錫市(shi)新建的(de)(de)(de)變(bian)電(dian)(dian)(dian)(dian)(dian)站都采(cai)(cai)用先(xian)進的(de)(de)(de)一次設(she)備(bei)和具(ju)備(bei)綜合(he)自動化功能(neng)的(de)(de)(de)二次設(she)備(bei)，其(qi)中空港(gang)、新明、唐義等(deng)三座變(bian)電(dian)(dian)(dian)(dian)(dian)站還具(ju)備(bei)遠方程序化操作的(de)(de)(de)功能(neng)。
為(wei)確(que)保各新建(jian)變(bian)電(dian)站安(an)全投運(yun)(yun)(yun)(yun)，無(wu)錫供(gong)電(dian)公(gong)司克服(fu)工作(zuo)量大、投運(yun)(yun)(yun)(yun)間隔(ge)短等(deng)困難，提前(qian)介入，精心(xin)謀劃，做好投運(yun)(yun)(yun)(yun)驗(yan)收(shou)(shou)各項準備(bei)工作(zuo)。該公(gong)司實(shi)行(xing)新建(jian)變(bian)電(dian)站驗(yan)收(shou)(shou)項目負責人制(zhi)，對新建(jian)變(bian)電(dian)站逐個制(zhi)定(ding)了詳(xiang)細的(de)驗(yan)收(shou)(shou)方案，編寫現(xian)場運(yun)(yun)(yun)(yun)行(xing)規(gui)程，編制(zhi)了驗(yan)收(shou)(shou)作(zuo)業卡。運(yun)(yun)(yun)(yun)行(xing)管理人員深入現(xian)場，實(shi)地勘察，及時掌握各變(bian)電(dian)站設備(bei)、接線及二次回路的(de)危險(xian)點(dian)和(he)技(ji)術難點(dian)，從(cong)組織措(cuo)施和(he)技(ji)術措(cuo)施兩方面(mian)進(jin)行(xing)把(ba)關。
