江蘇華辰(chen)發(fa)明了一(yi)種干式(shi)變壓(ya)器(qi)低壓(ya)箔(bo)式(shi)線圈引線結(jie)構(gou)(gou)及引線繞制工藝，涉及變壓(ya)器(qi)領(ling)域(yu)。發(fa)明采用雙層(ceng)箔(bo)分流(liu)疊繞結(jie)構(gou)(gou)纏(chan)繞，每層(ceng)銅箔(bo)采用單(dan)獨的引出結(jie)構(gou)(gou)，使得(de)低壓(ya)線圈額(e)定(ding)電流(liu)平分到每組(zu)引線銅排(pai)上，有(you)效避免了電流(liu)過大時導致的銅排(pai)適用度小的問(wen)題，同(tong)時也有(you)效縮(suo)減了現場使用場地。

施耐德電(dian)(dian)(dian)(dian)(dian)氣發(fa)明了一種變壓(ya)器(qi)保(bao)護(hu)(hu)方法(fa)、裝置(zhi)、繼(ji)電(dian)(dian)(dian)(dian)(dian)保(bao)護(hu)(hu)器(qi)及(ji)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)系統(tong)(tong)。該(gai)方法(fa)提供(gong)(gong)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)系統(tong)(tong)的(de)(de)拓(tuo)(tuo)(tuo)撲結(jie)構與保(bao)護(hu)(hu)電(dian)(dian)(dian)(dian)(dian)流(liu)整定值之(zhi)間的(de)(de)預(yu)(yu)設對(dui)應(ying)關(guan)(guan)系，任(ren)一繼(ji)電(dian)(dian)(dian)(dian)(dian)保(bao)護(hu)(hu)器(qi)在獲(huo)取(qu)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)系統(tong)(tong)的(de)(de)拓(tuo)(tuo)(tuo)撲結(jie)構信(xin)息(xi)之(zhi)后，基于該(gai)預(yu)(yu)設對(dui)應(ying)關(guan)(guan)系確定與供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)系統(tong)(tong)的(de)(de)當(dang)前拓(tuo)(tuo)(tuo)撲結(jie)構對(dui)應(ying)的(de)(de)目(mu)標保(bao)護(hu)(hu)電(dian)(dian)(dian)(dian)(dian)流(liu)整定值，還會(hui)獲(huo)取(qu)其所(suo)屬(shu)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)子系統(tong)(tong)內的(de)(de)變壓(ya)器(qi)的(de)(de)進(jin)線(xian)側(ce)電(dian)(dian)(dian)(dian)(dian)流(liu)以及(ji)所(suo)屬(shu)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)子系統(tong)(tong)內的(de)(de)弧光傳感(gan)器(qi)的(de)(de)弧光檢(jian)測(ce)信(xin)號，在進(jin)線(xian)側(ce)電(dian)(dian)(dian)(dian)(dian)流(liu)大于等于目(mu)標保(bao)護(hu)(hu)電(dian)(dian)(dian)(dian)(dian)流(liu)整定值，且弧光檢(jian)測(ce)信(xin)號表征檢(jian)測(ce)到弧光的(de)(de)情(qing)況下，斷開所(suo)屬(shu)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)子系統(tong)(tong)內的(de)(de)變壓(ya)器(qi)與供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)網絡的(de)(de)連接(jie)，方案(an)兼(jian)顧保(bao)護(hu)(hu)靈敏度及(ji)保(bao)護(hu)(hu)穩定性(xing)，能夠解決(jue)現有(you)技術中變壓(ya)器(qi)保(bao)護(hu)(hu)方法(fa)存在的(de)(de)問題。

保(bao)變(bian)電(dian)氣發明了一種變(bian)壓(ya)(ya)器有載開關電(dian)位電(dian)阻的(de)安(an)裝結(jie)構及方(fang)法(fa)，屬于變(bian)壓(ya)(ya)器制作技術(shu)領域。發明的(de)有益效果是(shi)：既滿足安(an)裝需求(qiu)，同時又能降低(di)開關固定板的(de)強度要求(qiu)，并且能充(chong)分(fen)利用油箱內的(de)空間(jian)，方(fang)便引線的(de)裝配。

特變電(dian)工(gong)申請了一種(zhong)“變壓器絕(jue)緣件(jian)的(de)測(ce)試工(gong)裝”發明(ming)專利。采用此發明(ming)測(ce)試工(gong)裝能夠得(de)到對(dui)應不(bu)同(tong)(tong)抽真空階段的(de)絕(jue)緣件(jian)樣品，以及得(de)到對(dui)應不(bu)同(tong)(tong)注油階段的(de)絕(jue)緣件(jian)樣品。

小編在(zai)(zai)國家(jia)知識產(chan)權局網(wang)站中以“變(bian)(bian)壓(ya)器(qi)”為“發明名稱(cheng)”進(jin)行檢(jian)索，發現截至(zhi)2023年(nian)10月(yue)20日，變(bian)(bian)壓(ya)器(qi)行業(ye)(ye)共計有115067項專利(li)(li)。在(zai)(zai)2018年(nian)至(zhi)2022年(nian)期間，變(bian)(bian)壓(ya)器(qi)專利(li)(li)申請數量整體呈(cheng)波動趨勢，其中2020年(nian)全行業(ye)(ye)申請最(zui)多，全年(nian)共申請了13673項變(bian)(bian)壓(ya)器(qi)專利(li)(li)。
