9月18日，“35千伏(fu)戶(hu)外式節能(neng)型電網限流(liu)裝(zhuang)置(zhi)研制與(yu)應用”在寧(ning)夏銀川通(tong)過了寧(ning)夏科技(ji)成(cheng)果管理中心組(zu)織(zhi)的鑒定。鑒定委(wei)員會認為(wei)，該裝(zhuang)置(zhi)在戶(hu)外限流(liu)裝(zhuang)置(zhi)的集成(cheng)技(ji)術(shu)上填補了國內(nei)空白。
當系統短(duan)(duan)路(lu)(lu)電(dian)(dian)(dian)(dian)(dian)流(liu)達到設定的(de)(de)(de)動作值(zhi)時(shi)(shi)，該(gai)裝(zhuang)置(zhi)能在極短(duan)(duan)時(shi)(shi)間(jian)內(nei)將限流(liu)電(dian)(dian)(dian)(dian)(dian)抗器(qi)快速接(jie)入限制短(duan)(duan)路(lu)(lu)電(dian)(dian)(dian)(dian)(dian)流(liu)，避免過大(da)(da)的(de)(de)(de)短(duan)(duan)路(lu)(lu)電(dian)(dian)(dian)(dian)(dian)流(liu)沖擊變壓器(qi)和系統。同(tong)時(shi)(shi)有效避免了限流(liu)電(dian)(dian)(dian)(dian)(dian)抗器(qi)運行時(shi)(shi)造成的(de)(de)(de)系統電(dian)(dian)(dian)(dian)(dian)壓降低和運行損耗(hao)巨大(da)(da)的(de)(de)(de)問題(ti)。這種全新(xin)的(de)(de)(de)節能環保型電(dian)(dian)(dian)(dian)(dian)網(wang)限流(liu)裝(zhuang)置(zhi)不(bu)僅(jin)可(ke)解決220千伏及以下電(dian)(dian)(dian)(dian)(dian)網(wang)短(duan)(duan)路(lu)(lu)電(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)超標問題(ti)，還會帶(dai)來巨大(da)(da)的(de)(de)(de)經濟效益。
該裝(zhuang)置由寧夏電力科學研(yan)究院與安徽眾(zhong)鑫電力技術有(you)限公司歷經(jing)兩年(nian)研(yan)制成(cheng)功，8月31日在(zai)銀川電網(wang)投入運(yun)行。
