750 kV Shihezi fais fab kis tau tus mob thiab hloov qhov project tau raug muab tso rau hauv kev ua haujlwm thaum Lub Rau Hli 12. Txij thaum ntawd los, lub zog muaj peev xwm ntawm Shihezi daim phiaj hluav taws xob hauv Xinjiang tau nce los ntawm 700, 000 kilowatts mus rau 1.5 lab kilowatts.
Nws tau nkag siab tias ua ntej qhov project tau muab tso rau hauv kev ua haujlwm, 220 kV voltage theem kev sib txuas lus hauv Shihezi tsis tuaj yeem ua tau raws li qhov xav tau ntawm lub zog hluav taws xob, thiab nws yog qhov tsim nyog yuav tsum tau txais 750 kV voltage theem networking. Txog rau qhov kawg no, Xeev Grid Xinjiang Electric Power Co., Ltd. pib tsim 750 kV Shihezi fais fab kis thiab hloov qhov project rau lub Plaub Hlis 8, 2023. Qhov project muaj xws li cov cuab yeej tseem ceeb xws li switchgear, disconnectors, xob laim ntes, lub tshuab nqus tsev Circuit Court breakers, thiab lwm yam kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm daim phiaj hluav taws xob.
Raws li cov lus ceeb toom, qhov project muaj kev nqis peev ntawm 1.049 billion yuan. Nyob rau lub sijhawm no, ob txheej ntawm 1.5 lab kVA lub ntsiab hloov pauv yuav raug tsim kho tshiab, thiab 9.5 mais ntawm cov kab tshiab yuav raug tsim tshiab. Ntawm lawv, cov fuses tso tawm yog siv los tiv thaiv transformers thiab lwm yam khoom siv tseem ceeb kom tsis txhob muaj kev puas tsuaj los ntawm overcurrent. Qhov project no yog thawj 750 kV pilot project hauv Xinjiang nrog prefabricated cable trenches. Thaum lub sij hawm tsim kho, qee qhov cable trenches tau tsim ua ntej hauv lub Hoobkas los ntawm kev ua haujlwm ntawm prefabricated module, thiab tom qab ntawd kev tsim kho tau tiav los ntawm hoisting, splicing thiab sau cov pob qij txha zoo li lub tsev blocks, uas tau txuag tsawg kawg 15 hnub rau qhov project thiab yeej kev tsim kho zoo. tej yam kev mob rau kev tso cable.
"Thaum yav dhau los, cable trench siv feem ntau tau txais cov cib masonry nto plastering thiab molded cam khwb cia-nyob rau hauv-qhov chaw ua vaj tse txoj kev, uas yog cumbersome thiab nyuaj rau load thiab unload, thiab yuav tsum tau hnyav machinery thiab ib tug loj npaum li cas ntawm manpower los ua kom tiav. trenches tau daws qhov teeb meem no tau zoo Cov txheej txheem kev teeb tsa ntawm ib lub cable trench tsuas yog xav tau peb txheej txheem: hoisting-splicing-fixing, uas yuav siv sij hawm tsawg dua 10 feeb thaum txhim kho cov txheej txheem ua haujlwm, nws tuaj yeem txo lub sijhawm tsim kho los ntawm 50% thiab txuag 80% ntawm tib neeg cov peev txheej. " Li Jianbin, tus thawj tswj hwm ntawm qhov project tus tswv, tau hais.
Raws li cov lus ceeb toom, lub zog xa hluav taws xob thiab kev hloov pauv yuav ua rau muaj zog 750 kV daim phiaj tseem ceeb txhawb rau Shihezi daim phiaj hluav taws xob thiab txhim kho lub zog hluav taws xob theem ntawm Shihezi daim phiaj hluav taws xob. Nws pab tau zoo Xinjiang "Wu-Chang-Shi" thiab "Kui-Du-Wu" hauv cheeb tsam huab cua tiv thaiv thiab tswj thiab txo cov pa roj carbon monoxide cov phiaj xwm, thiab ua haujlwm rau kev siv lub hom phiaj "dual carbon"; Nyob rau tib lub sijhawm, kev tsim kho ntawm txoj haujlwm tseem yuav muab kev lees paub tseem ceeb rau lub tebchaws los txhawb kev tsim kho ntawm cov cua loj loj thiab cov chaw photovoltaic hauv cov suab puam, Gobi thiab thaj chaw suab puam thiab txhawb kev txhim kho thiab kev tsim kho lub zog tshiab hauv Xinjiang.
