據介(jie)紹，GIS/GIL現(xian)(xian)場(chang)(chang)交流(liu)耐(nai)(nai)(nai)壓(ya)試(shi)驗(yan)(yan)(yan)(yan)是(shi)發現(xian)(xian)組合電(dian)(dian)器(qi)設(she)備(bei)(bei)絕緣缺(que)陷的(de)有效手(shou)段，是(shi)確保組合電(dian)(dian)器(qi)設(she)備(bei)(bei)投運后具(ju)備(bei)(bei)承受(shou)過電(dian)(dian)壓(ya)能(neng)力的(de)重要保證。GIS/GIL設(she)備(bei)(bei)現(xian)(xian)場(chang)(chang)耐(nai)(nai)(nai)壓(ya)試(shi)驗(yan)(yan)(yan)(yan)作(zuo)為(wei)現(xian)(xian)場(chang)(chang)難(nan)(nan)度高、工(gong)作(zuo)量大的(de)交接試(shi)驗(yan)(yan)(yan)(yan)，工(gong)頻(pin)耐(nai)(nai)(nai)壓(ya)試(shi)驗(yan)(yan)(yan)(yan)裝置(zhi)具(ju)有成(cheng)套裝置(zhi)部件多、體積龐(pang)大、現(xian)(xian)場(chang)(chang)組裝搭建(jian)耗時費力，需多次依賴(lai)吊(diao)車等難(nan)(nan)題，當前(qian)普通的(de)1100千伏 GIS耐(nai)(nai)(nai)壓(ya)設(she)備(bei)(bei)從正(zheng)式(shi)搭建(jian)到耐(nai)(nai)(nai)壓(ya)試(shi)驗(yan)(yan)(yan)(yan)開(kai)始往往需要12小(xiao)時,嚴重制約了現(xian)(xian)場(chang)(chang)工(gong)頻(pin)耐(nai)(nai)(nai)壓(ya)試(shi)驗(yan)(yan)(yan)(yan)的(de)開(kai)展；本次新型工(gong)頻(pin)交流(liu)耐(nai)(nai)(nai)壓(ya)試(shi)驗(yan)(yan)(yan)(yan)裝置(zhi)的(de)成(cheng)功試(shi)驗(yan)(yan)(yan)(yan)，標志著省(sheng)電(dian)(dian)科院GIS/GIL交流(liu)耐(nai)(nai)(nai)壓(ya)試(shi)驗(yan)(yan)(yan)(yan)技術能(neng)力邁上了新臺階(jie)。

新型試(shi)(shi)驗(yan)裝(zhuang)(zhuang)(zhuang)置的(de)研制過程中，省電科院結(jie)合1100千(qian)(qian)伏(fu)(fu) GIS設備現場(chang)經(jing)驗(yan)和(he)1100千(qian)(qian)伏(fu)(fu)蘇通GIL管(guan)廊工程需求(qiu)，在深(shen)入分(fen)析研究耐壓(ya)試(shi)(shi)驗(yan)設備關鍵性難點問題的(de)基(ji)礎上，提出了(le)特高壓(ya)GIS/GIL一(yi)體化(hua)耐壓(ya)試(shi)(shi)驗(yan)裝(zhuang)(zhuang)(zhuang)置設計(ji)方案，該試(shi)(shi)驗(yan)裝(zhuang)(zhuang)(zhuang)置創新研制了(le)大容(rong)量自升(sheng)舉式(shi)高壓(ya)電抗(kang)器、融入式(shi)電感分(fen)壓(ya)測量系統(tong)、大直徑(jing)充氣式(shi)均壓(ya)環(huan)等新型部件，試(shi)(shi)驗(yan)時(shi)無需安裝(zhuang)(zhuang)(zhuang)均壓(ya)環(huan)及(ji)分(fen)壓(ya)器，具有結(jie)構緊湊、高度集成、質量輕便、易(yi)于(yu)拆裝(zhuang)(zhuang)(zhuang)等優勢，使1100千(qian)(qian)伏(fu)(fu) GIS現場(chang)工頻耐壓(ya)裝(zhuang)(zhuang)(zhuang)置搭建時(shi)間(jian)從12小時(shi)(550千(qian)(qian)伏(fu)(fu) GIS耐壓(ya)試(shi)(shi)驗(yan)裝(zhuang)(zhuang)(zhuang)置搭建也需5-8小時(shi))縮(suo)短至2小時(shi)，極大地(di)提升(sheng)現場(chang)耐壓(ya)試(shi)(shi)驗(yan)效率。
