6月5日(ri)，國網天(tian)津電(dian)科院(yuan)技術(shu)人(ren)員完成濱海(hai)500千伏變電(dian)站(zhan)4號主變壓器局部放(fang)電(dian)試(shi)驗。

濱海(hai)變(bian)(bian)電(dian)(dian)站擴建工程計劃新投1號(hao)(hao)、4號(hao)(hao)兩組單(dan)相(xiang)主變(bian)(bian)，4號(hao)(hao)主變(bian)(bian)首(shou)先安裝完(wan)畢并具備(bei)試(shi)驗(yan)(yan)條(tiao)件(jian)，需要電(dian)(dian)科(ke)院(yuan)完(wan)成4號(hao)(hao)主變(bian)(bian)三臺(tai)單(dan)相(xiang)變(bian)(bian)壓器(qi)局(ju)部放(fang)電(dian)(dian)試(shi)驗(yan)(yan)。電(dian)(dian)科(ke)院(yuan)對此次(ci)檢(jian)測任(ren)務高度重視(shi)，提前(qian)開展試(shi)驗(yan)(yan)前(qian)現(xian)場(chang)(chang)勘察與風險(xian)點辨識，編制了局(ju)部放(fang)電(dian)(dian)試(shi)驗(yan)(yan)方(fang)案，梳(shu)理了現(xian)場(chang)(chang)安全措施、防疫措施、試(shi)驗(yan)(yan)設(she)備(bei)清單(dan)及大型作業(ye)車(che)輛協同工作流程，充(chong)分做(zuo)好試(shi)驗(yan)(yan)前(qian)期(qi)各項準(zhun)備(bei)。

在現(xian)(xian)場(chang)，電(dian)科院技術人員(yuan)完(wan)(wan)成試(shi)驗(yan)設備布設和試(shi)驗(yan)回路連接后，在復雜的現(xian)(xian)場(chang)環(huan)境下，通過放(fang)電(dian)信號相(xiang)位同步、紫外(wai)檢(jian)測(ce)等方法(fa)有效排除現(xian)(xian)場(chang)干擾源，保證局部放(fang)電(dian)試(shi)驗(yan)順(shun)利進行，最終完(wan)(wan)成了三(san)臺單相(xiang)變壓器(qi)的局部放(fang)電(dian)試(shi)驗(yan)。

下一(yi)步，電(dian)科院將持續(xu)發(fa)揮(hui)人才和技術優勢，為(wei)電(dian)力運(yun)行單位提供更(geng)有(you)力技術支撐，為(wei)天津電(dian)網安全運(yun)行保駕護航(hang)。
