Thaum Lub Xya Hli 25, Hami mus rau Chongqing ± 800 kV UHV DC kis tau tus mob qhov project tau txais qhov kawg 500 kV txhawb qhov project (Phase II) (tom qab no hu ua: Harbin thiab Chongqing txhawb txoj haujlwm) tau pib thawj lub hauv paus rotary excavation hauv Hechuan District, Chongqing, uas txhais tau tias qhov project yog nyob rau hauv tag nrho viav vias.
Nws tau tshaj tawm tias tag nrho cov peev txheej ntawm Harbin Heavy Industry txhawb nqa qhov project yog kwv yees li 1.57 billion yuan, suav nrog 5 txoj haujlwm overhead line project sub-projects thiab 9 transformer bay project sub-projects, suav nrog kev teeb tsa thiab commissioning ntawm cov cuab yeej tseem ceeb xws li hloov cov txee, cais tawm. switches, thiab xob laim ntes. Qhov project tau tsim tag nrho ntawm 311 lub tuam tsev hlau tshiab, 247.3 mais ntawm cov kab nyiaj siv ua haujlwm, thiab kho dua tshiab 37.6 mais ntawm cov kab xa hluav taws xob. Nws hla 6 lub nroog thiab nroog, 22 lub nroog thiab txoj kev hauv Tongliang, Hechuan, Beibei, Yubei, Changshou, thiab Bishan hauv Chongqing, thiab 1, 000 Tongliang tshiab tau tsim. Lub 500-kilovolt substation muaj ob lub sijhawm tawm mus, thiab yim 500-kilovolt substations suav nrog Changshou Chaw Nres Tsheb, Chenjiaqiao Chaw Nres Tsheb, thiab Banqiao Chaw Nres Nkoj tau raug kho dua tshiab, suav nrog kev hloov lub tshuab nqus tsev vacuum thiab ntxiv cov fuses tawm los txhim kho cov khoom siv. kev ua tau zoo.
Tom qab lub luag haujlwm tseem ceeb ntawm Harbin-Chongqing txhawb nqa qhov project tiav los ntawm qhov kawg ntawm 2025, nws yuav tuaj yeem xa ncaj qha Xinjiang lub zog huv mus rau hauv Chongqing nroog cheeb tsam. Lub peev xwm siv hluav taws xob ntau tshaj plaws txhua xyoo yuav ntau dua 36 billion kilowatt-teev (kWh), suav txog kwv yees li 20% ntawm tag nrho cov hluav taws xob siv hauv Chongqing hauv 2023. Ib lub hlis twg ntawm cov khoom siv hluav taws xob kuj tuaj yeem muab kev txhawb zog ruaj ntseg, nyab xeeb thiab huv si. Chongqing cheeb tsam, zoo txhawb kev tsim kho ntawm ntau lub zog kev ruaj ntseg hauv Chongqing, thiab txhawb nqa kev lag luam zoo thiab kev loj hlob ntawm lub nroog ncaj qha raws li tsoomfwv Central.
Nyob rau tib lub sijhawm, tom qab qhov project no tau muab tso rau hauv kev ua haujlwm, Xinjiang lub zog huv tuaj yeem muab faib rau hauv thaj chaw loj hauv nroog thiab sab qaum teb ntawm Chongqing, muab kev txhawb nqa ncaj qha rau 500 kV substations, tshwj xeeb tshaj yog los ntawm optimizing lub transformer configuration, txhawb Chongqing lub nruab nrab mus rau lub sij hawm ntev "ob lub voj voog thiab ob lub radiators" Kev tsim kho ntawm 500 kV lub ntsiab kab sib chaws tau txhawb nqa kev txhim kho thiab kev loj hlob ntawm Chongqing lub ntsiab kab sib chaws thiab pab ua kom tau raws li cov kev xav tau ntawm lub nroog kev lag luam ruaj khov thiab noj qab nyob zoo. thiab kev loj hlob ntawm kev sib raug zoo raws li qhov xwm txheej tshiab.
