Tsis ntev los no, thawj zaug UHV AC project nyob rau sab hnub poob ntawm Tuam Tshoj, Sichuan-Chongqing 1000 kV UHV AC project ntawm State Grid Co. Qhov project yuav tsim plaub qhov tshiab UHV substations hauv Ganzi, Tianfu South, Chengdu East thiab Tongliang, Chongqing, nrog rau transformer. muaj peev xwm ntawm 24 lab kVA thiab 658 km ntawm cov kab tshiab ob npaug rov qab UHV, nrog rau tag nrho cov peev ntawm 28.8 billion RMB, thiab tau teem sijhawm yuav tsum tau muab tso rau hauv kev ua haujlwm ua ntej lub caij ntuj sov ncov xyoo 2025.
Piv nrog rau cov haujlwm zoo sib xws ua tiav kom deb li deb, Sichuan-Chongqing UHV AC project yog lub ntiaj teb qhov siab tshaj plaws UHV AC kis tau tus mob qhov project, qhov siab tshaj plaws ntawm UHV kis tau tus mob yuav dhia los ntawm qhov uas twb muaj lawm 2300 meters mus rau ntau tshaj 4700 meters; qhov siab tshaj plaws ntawm Tuam Tshoj lub 1000 kV substation yuav dhia los ntawm 1300 meters mus rau 3500 meters, thiab cov khoom siv loj yuav nce ntau dua 30 feem pua. Kev tsim kho ntawm qhov project ntsib qhov kev sib tw triple ntawm qhov siab siab, hnyav dej khov npog thiab siab seismic siv tib lub sijhawm. Txog rau qhov kawg no, pab pawg tshawb fawb kev lag luam ntawm Xeev Grid Corporation tau kov yeej cov thev naus laus zis tseem ceeb ntawm qhov chaw siab siab huab cua sib txawv, kev rwb thaiv tsev sab nraud, hluav taws xob ib puag ncig thiab cov khoom siv txhim kho, thiab ua tiav cov txheej txheem tag nrho ntawm qhov siab siab EHV cov cuab yeej siv thiab cov cuab yeej siv tshwj xeeb, tso cov technical foundation thawj zaug nyob rau hauv lub ntiaj teb no ua kom tiav kev tsim kho ntawm EHV ntawm qhov siab siab thiab hnyav ice npog.
Sichuan-Chongqing UHV AC project yog qhov pib ua haujlwm txuas rau Sichuan thiab Chongqing lub zog thiab chaw thau khoom thiab tsim cov pob txha ntawm sab hnub poob UHV AC network. Tom qab ua tiav ntawm qhov project, qhov voltage theem ntawm lub network tseem ceeb ntawm Tuam Tshoj txoj kab hluav taws xob sab qab teb sab hnub poob yuav raug tsa los ntawm 500 kV mus rau 1000 kV, uas yuav xa hluav taws xob huv ntawm ntau dua 35 billion degrees hauv ib xyoos, uas tuaj yeem ua tau raws li qhov xav tau ntawm ntau haiv neeg. kev tsim hluav taws xob thiab kev sib txuas lus, ua haujlwm tau zoo ntawm hluav taws xob los ntawm sab hnub poob Tuam Tshoj thiab Tibet, thiab txhim kho tag nrho lub zog ruaj ntseg muaj peev xwm ntawm ob lub nroog kev lag luam hauv Chengdu thiab Chongqing. Nws yog ib qho tseem ceeb los tsim kom muaj lub zog huv, tsis tshua muaj roj, muaj kev nyab xeeb thiab muaj txiaj ntsig zoo thiab lav lub zog ruaj ntseg hauv cheeb tsam.
