單相變(bian)壓器(qi)(qi)(qi)(qi)--隨著國家(jia)節能政策的(de)深入推進(jin)，節能單相變(bian)壓器(qi)(qi)(qi)(qi)日(ri)益普(pu)及，據山東聊(liao)城變(bian)壓器(qi)(qi)(qi)(qi)有限公(gong)司統計，2012旋(xuan)轉變(bian)頻變(bian)壓器(qi)(qi)(qi)(qi)銷量(liang)同(tong)比增長(chang)7%，遠(yuan)遠(yuan)高(gao)于普(pu)通變(bian)壓器(qi)(qi)(qi)(qi)的(de)銷量(liang)。高(gao)能效變(bian)壓器(qi)(qi)(qi)(qi)的(de)普(pu)及對干式變(bian)壓器(qi)(qi)(qi)(qi)等配(pei)套產業也提出了更(geng)高(gao)的(de)要求。 

110千伏干式變壓器格(ge)構式構架最高的一基(ji)塔高達40米(mi)(mi)、最低的(de)也有20米(mi)(mi)。安裝時要求樁(zhuang)(zhuang)基(ji)澆鑄與(yu)之(zhi)配(pei)套(tao)更加精(jing)準。32個基(ji)礎地角螺栓，哪怕有一個出現誤差(cha)，就會造成干式變壓(ya)器整(zheng)基(ji)構(gou)架無法安裝。為達到構(gou)架與(yu)樁(zhuang)(zhuang)基(ji)螺栓的(de)無縫(feng)對接，電網建設員工(gong)事先(xian)采用微差(cha)爆破技術，對孔樁(zhuang)(zhuang)巖石施(shi)工(gong)爆破，以滿足單相變壓(ya)器樁(zhuang)(zhuang)基(ji)澆筑要求。

為了做好前(qian)期策(ce)劃(hua)，山(shan)東(dong)聊城變壓器有限公司抽調精(jing)銳力量參與施(shi)工(gong)。根據冬季(ji)施(shi)工(gong)特點，開(kai)展(zhan)冬季(ji)安全(quan)質量大檢(jian)查(cha)活動，落實安全(quan)防范措施(shi)，對(dui)重(zhong)點項目(mu)、重(zhong)點環(huan)節、重(zhong)點部位加強安全(quan)監(jian)督(du)，強化過(guo)程管控(kong)，確(que)保(bao)該(gai)工(gong)程按(an)計劃(hua)開(kai)工(gong)、按(an)節點推進、按(an)目(mu)標投運，為山(shan)東(dong)電網安全(quan)迎峰度冬以及春節保(bao)電工(gong)作交上一份滿意的答卷

單相(xiang)變壓(ya)器在(zai)造成低(di)電(dian)壓(ya)的眾多原因中，配變過載是關鍵。2012年3月(yue)起，惠(hui)州供(gong)電(dian)局對各縣區進(jin)行臺區普查工(gong)作，詳細考察各臺區容量、臺區負(fu)荷、低(di)壓(ya)用(yong)戶(hu)數、低(di)壓(ya)出線(xian)情況、首末端電(dian)壓(ya)等(deng)情況，按實(shi)際(ji)情況提(ti)出解決措施。9月(yue)，現場施工(gong)改造工(gong)作在(zai)各縣區局陸續(xu)鋪開。

隨著(zhu)單相變(bian)(bian)(bian)壓(ya)器(qi)(qi)發展，國(guo)家(jia)電(dian)網公司(si)提(ti)出(chu)(chu)了(le)建設新一代(dai)智能(neng)變(bian)(bian)(bian)電(dian)站的規劃，對智能(neng)干式變(bian)(bian)(bian)壓(ya)器(qi)(qi)性能(neng)提(ti)出(chu)(chu)了(le)更(geng)高要求。2011年12月，公司(si)先后兩次(ci)召開關于“智能(neng)高壓(ya)設備檢(jian)測試驗(yan)”的會議，明確變(bian)(bian)(bian)壓(ya)器(qi)(qi)制造商必須對智能(neng)變(bian)(bian)(bian)壓(ya)器(qi)(qi)整體(ti)（變(bian)(bian)(bian)壓(ya)器(qi)(qi)本(ben)體(ti)、傳感器(qi)(qi)、智能(neng)組件）負責，具備智能(neng)變(bian)(bian)(bian)壓(ya)器(qi)(qi)的檢(jian)測試驗(yan)能(neng)力。這(zhe)為智能(neng)變(bian)(bian)(bian)壓(ya)器(qi)(qi)的發展指明了(le)方向(xiang)，提(ti)出(chu)(chu)了(le)新的要求，對于企業而言，機遇與挑(tiao)戰并存。

山東聊(liao)城變(bian)壓(ya)器(qi)(qi)有(you)限公(gong)司生(sheng)產的單相隔離變(bian)壓(ya)器(qi)(qi)功(gong)能特點：

特點：
1、單相變壓器抗干擾作用：如通過Y/△接線的隔離變壓器后，能夠阻止一部分諧波的傳輸；
2、單相變壓器阻抗變換作用：增加系統阻抗，使保護裝置等容易配合；
3、單相變壓器穩定系統電壓的作用：如啟動大負荷設備時，減少對系統電壓的影響；
4、防止系統接地的作用：當隔離變壓器負荷側發生單相接地時，不會造成整個系統（隔離變壓器以上部分）單相接地；
5、降低短(duan)路(lu)電(dian)流：當負荷側(ce)發生短(duan)路(lu)事(shi)故時，限制系(xi)統的(de)短(duan)路(lu)電(dian)流；
