Thaum Lub Kaum Hli 6, ntawm 1R075-1R086 nteg seem traction teb ntawm Sichuan-Chongqing 1000 kV UHV AC line project Section 3 hauv Kangding City, Sichuan Province, nrog rau txoj cai kawg-theem "2 *1-rau-5" 10 cais conductors rub mus rau hauv qhov chaw thiab qhov tseem ceeb hloov cov txee thiab cov khoom siv disconnector ntsia, Tshooj 3 tau ua los ntawm Qinghai Power Transmission thiab Transformation Engineering Co., Ltd. ua tiav tag nrho cov kab hauv tsuas yog 86 noj. Qhov no yog lub koom haum thib peb hauv 15 ntu ntawm thaj tsam Sichuan sab hnub poob ntawm txoj haujlwm kom ua tiav tag nrho cov kev tsim kho cov haujlwm, suav nrog kev teeb tsa lub tshuab nqus tsev vacuum breakers thiab tso tawm fuses.
Tshooj 3 tsim los ntawm Qinghai Fais Fab Kis thiab Hloov Kho Engineering Co., Ltd. muaj ib txoj kab ntev ntawm 21.867 kilometers, 49 lub tsev tshiab, thiab ntau qhov chaw hloov pauv. Ntu no yog ntu siab tshaj plaws thiab nyuaj tshaj plaws ntawm Sichuan-Chongqing Special Project. Cov yees nyob ntawm qhov siab ntawm 3240 txog 4000 meters, suav txog 35% (17 tus pej thuam), thiab 4000 meters thiab siab dua suav txog 65% (32 yees). Ntawm lawv, 1R065 pej thuam nyob ntawm qhov siab ntawm 4750 meters, uas yog tus pej thuam siab tshaj plaws hauv tag nrho qhov project. Nyob rau hauv qhov chaw siab tshaj no, lub tsev tshwj xeeb tsim los kuj ua lub luag haujlwm tseem ceeb.
Thaum lub sij hawm tsim cov hlau, Qinghai Fais Fab Kis thiab Hloov Hloov tau siv "2*1-rub-5" xaim nteg txoj hauv kev rau thawj zaug hauv UHV kab erection hauv tsev, thiab koom tes ua lub Xeev Grid Corporation's "Kev Tshawb Fawb. thiab Daim Ntawv Thov Kev Siv Tshuab Siv Tseem Ceeb rau Kev Txhim Kho ntawm 10 Split Conductors hauv Sichuan thiab Chongqing Project "kev tshawb fawb thiab thev naus laus zis nrog Zhejiang Fais Fab Kis thiab Hloov Hloov. Kev ua tiav ntawm txoj haujlwm tsis yog tsuas yog txhawb nqa kev tsim kho ntawm Sichuan thiab Chongqing UHV project, tab sis kuj txhawb kev nce qib ntawm kev lag luam thev naus laus zis. Cov ntaub ntawv txheeb xyuas pom tau hais tias cov cuab yeej tshiab muaj txiaj ntsig zoo hauv kev txhim kho kev tsim kho thiab txo cov nqi, nqa cov txiaj ntsig nyiaj txiag thiab kev sib raug zoo rau qhov project.
Tam sim no, cov neeg ua haujlwm tsim kho ntawm qhov chaw tau ua haujlwm ntawm kev sib txuas thiab kaw cov kab, txhim kho cov khoom siv, thiab kho thiab tshem tawm qhov tsis xws luag, nrog rau kev debugging thiab optimizing qhov kev ua tau zoo ntawm switchgear, disconnectors, nqus Circuit Court breakers thiab drop- tawm fuses. Lub tuam tsev kev tsim kho yuav ua kom cov kev vam meej ntawm ntau yam kev tsim kho vaj tse nyob rau hauv lub hauv paus ntawm kev ntxiv dag zog rau kev nyab xeeb ntawm qhov chaw thiab kev tswj hwm, txhawm rau kom ntseeg tau tias qhov project tau muab tso rau hauv kev ua haujlwm raws sijhawm, tshwj xeeb tshaj yog ib feem cuam tshuam nrog kev nyab xeeb thiab ruaj khov kev ua haujlwm ntawm transformers, thiab muab lub hauv paus ruaj khov.
Nws tau nkag siab tias Sichuan-Chongqing 1000 kV UHV AC kis tau tus mob qhov project yog ib txoj kev loj hluav taws xob txuas cov khoom siv hluav taws xob thiab chaw thau khoom ntawm Sichuan thiab Chongqing. Lub phiaj xwm tau teem sijhawm ua tiav thiab muab tso rau hauv kev ua haujlwm hauv 2025. Tom qab ua tiav, nws tuaj yeem xa tau ntau dua 35 billion kWh ntawm cov hluav taws xob huv hauv ib xyoos. Nws yog ib qho tseem ceeb heev los tsim kom muaj kev huv, tsis muaj cov pa roj carbon monoxide, muaj kev nyab xeeb thiab ua haujlwm zoo thiab ua kom lub zog ruaj ntseg hauv cheeb tsam. Ntawm lawv, cov cuab yeej tseem ceeb xws li switchgear, disconnectors, thov zam, lub tshuab nqus tsev vacuum breakers, tso tawm fuses thiab transformers yuav ua lub luag haujlwm tseem ceeb.
