11月6日，水電四局向家壩機電安裝工程項目部承擔安裝的向家壩水電站1號機定子通過整體交直流耐壓試驗，各項數據顯示首臺80萬千瓦機組發電機定子均達到了優良標準。
向家壩水(shui)(shui)電(dian)(dian)(dian)(dian)站發電(dian)(dian)(dian)(dian)機定(ding)子(zi)(zi)(zi)(zi)繞組(zu)采用全密閉空氣循環(huan)水(shui)(shui)冷卻方式，試驗(yan)(yan)是(shi)對定(ding)子(zi)(zi)(zi)(zi)各項(xiang)安(an)(an)裝(zhuang)(zhuang)(zhuang)質(zhi)量(liang)指(zhi)標的(de)(de)一個檢驗(yan)(yan)，定(ding)子(zi)(zi)(zi)(zi)是(shi)發電(dian)(dian)(dian)(dian)機的(de)(de)核心部(bu)件(jian)，安(an)(an)裝(zhuang)(zhuang)(zhuang)過(guo)(guo)程(cheng)中還要防(fang)止灰(hui)塵(chen)，在與(yu)土建(jian)相互施工(gong)(gong)(gong)(gong)的(de)(de)環(huan)境下，給(gei)安(an)(an)裝(zhuang)(zhuang)(zhuang)帶來了很大的(de)(de)困(kun)難，再加上安(an)(an)裝(zhuang)(zhuang)(zhuang)技術(shu)和質(zhi)量(liang)要求高(gao)，水(shui)(shui)電(dian)(dian)(dian)(dian)四局向家壩機電(dian)(dian)(dian)(dian)安(an)(an)裝(zhuang)(zhuang)(zhuang)工(gong)(gong)(gong)(gong)程(cheng)項(xiang)目部(bu)根(gen)據施工(gong)(gong)(gong)(gong)現場情況(kuang)，為保證1號機定(ding)子(zi)(zi)(zi)(zi)的(de)(de)施工(gong)(gong)(gong)(gong)質(zhi)量(liang)，在定(ding)子(zi)(zi)(zi)(zi)組(zu)裝(zhuang)(zhuang)(zhuang)施工(gong)(gong)(gong)(gong)中，從(cong)定(ding)子(zi)(zi)(zi)(zi)機座到疊片(pian)、上下層線(xian)棒安(an)(an)裝(zhuang)(zhuang)(zhuang)、焊接、匯流環(huan)安(an)(an)裝(zhuang)(zhuang)(zhuang)、驗(yan)(yan)收等(deng)等(deng)一系(xi)列的(de)(de)工(gong)(gong)(gong)(gong)序，搭設了防(fang)護棚，嚴格施工(gong)(gong)(gong)(gong)規范，以質(zhi)量(liang)求進度，嚴把每(mei)一道(dao)安(an)(an)裝(zhuang)(zhuang)(zhuang)工(gong)(gong)(gong)(gong)序，做到質(zhi)量(liang)控制、精(jing)心、精(jing)細(xi)，從(cong)而保證了施工(gong)(gong)(gong)(gong)質(zhi)量(liang)。通過(guo)(guo)對定(ding)子(zi)(zi)(zi)(zi)繞組(zu)絕緣(yuan)電(dian)(dian)(dian)(dian)阻測量(liang)、吸收比測量(liang)、極化指(zhi)數測量(liang)、繞組(zu)直流耐(nai)壓(ya)試驗(yan)(yan)、交流耐(nai)壓(ya)試驗(yan)(yan)等(deng)各項(xiang)試驗(yan)(yan)，此次首臺1號機組(zu)定(ding)子(zi)(zi)(zi)(zi)整體(ti)耐(nai)壓(ya)試驗(yan)(yan)的(de)(de)成(cheng)功(gong)，為該機組(zu)下一步轉子(zi)(zi)(zi)(zi)吊裝(zhuang)(zhuang)(zhuang)贏得了時間。
