4月1日(ri),國網寧夏超(chao)高(gao)壓(ya)(ya)公(gong)司檢修人員應(ying)用自主研制的變(bian)壓(ya)(ya)器中性(xing)點接(jie)(jie)地跨接(jie)(jie)分流(liu)裝置,帶電(dian)(dian)完成(cheng)330千(qian)伏(fu)迎(ying)水(shui)橋變(bian)電(dian)(dian)站(zhan)330千(qian)伏(fu)變(bian)壓(ya)(ya)器中性(xing)點限流(liu)電(dian)(dian)抗器接(jie)(jie)入,不(bu)停(ting)電(dian)(dian)完成(cheng)主變(bian)壓(ya)(ya)器抗短路能力不(bu)足(zu)隱患治(zhi)理(li)。
據了解,在變(bian)壓器(qi)中性(xing)點(dian)處加裝(zhuang)(zhuang)限流電(dian)抗器(qi)是(shi)提升(sheng)設備抗短路能力的有效解決措施,但由于需要停電(dian)開展(zhan),使得隱患(huan)治(zhi)理工作進展(zhan)緩慢。該公司研(yan)制的變(bian)壓器(qi)中性(xing)點(dian)接地跨接分(fen)流裝(zhuang)(zhuang)置(zhi),可避免因系(xi)統(tong)異常造成中性(xing)點(dian)電(dian)壓升(sheng)高的安全隱患(huan),實現(xian)不停電(dian)加裝(zhuang)(zhuang)中性(xing)點(dian)限流電(dian)抗器(qi)。
