Thaum lub Cuaj Hlis 10, nrog rau lub ntsiab transformer energized, 500 kV kis tau tus mob thiab transformation project ntawm Zhangjiakou Bashang nyob rau hauv Jibei Fais fab Grid tau officially muab tso rau hauv lub lag luam. Lub phiaj xwm tsis yog tsuas yog nruab nrog ntau cov cuab yeej tseem ceeb, suav nrog cov hloov pauv tseem ceeb thiab lub tshuab nqus tsev vacuum rau kev tswj lub hauv thiab tawm ntawm tam sim no, tab sis kuj tau nruab nrog cov hloov hluav taws xob cais kom ntseeg tau tias hluav taws xob sib cais thaum lub sijhawm tu, thiab cov cuab yeej hluav taws xob los tiv thaiv cov khoom siv los ntawm xob laim. .
Qhov project pib tsim nyob rau lub Peb Hlis 2023, thiab peb qhov tshiab 1200 MVA lub ntsiab transformers tau tsim. Cov transformers no yog lub hauv paus ntawm lub zog hluav taws xob thiab muaj lub luag haujlwm rau kev hloov pauv hluav taws xob thiab hluav taws xob faib. Nyob rau tib lub sijhawm, Zhangnan tshiab-reconnected Bashang ob-circuit 500 kV kis tau tus mob tau tsim, nrog txoj kev ntev ntawm 46.5 kilometers. Cov kab no tau nruab nrog cov fuses tso tawm kom txiav tawm qhov hluav taws xob hauv qhov xwm txheej luv luv lossis overload los tiv thaiv kev nyab xeeb ntawm tag nrho cov kab.
Lub 500 kV substation project nyob rau hauv Bashang tau tsim siab heev, siv lub dynamic reactive fais fab nyiaj them nyiaj ntaus ntawv (SVG) voltage saj zawg zog dynamic regulation technology, as well as advanced digital, networked, information sharing and safe protection technology monitoring systems. Tsis tas li ntawd, lub tsev tau txais kev sib sau ua ke, thiab lub tsev tiv thaiv tau txais ib chav tsev prefabricated-hom auxiliary chav, uas txhim kho kev tsim kho thiab kev nyab xeeb.
Txoj kab muaj txoj hauv kev nruj nruj, ntau qhov chaw rhiab heev, thiab ntau qhov kev hla ntawm txoj kab. Nws yuav tsum tau xyaum los ntawm Zhangbei-Xiong'an 1000 kV kab, Zhangbei yoog raws ± 500 kV kab, thiab hla Beijing-Zhangjiakou Expressway, Beijing-Zhangjiakou High-speed Railway, thiab ntau cov kav dej tseem ceeb (kab). Tau ntsib nrog cov kev cov nyom no, pab pawg tsim tsim tau ua tiav cov qauv zoo ntawm kev ua siab tawv sib ntaus sib tua, tsis ntshai ntawm kev nyuaj, thiab kev ua haujlwm nyuaj, kov yeej ntau yam teeb meem, thiab ua tiav cov qauv tsim qauv zoo raws li lub sijhawm, escorting qhov project kom tiav cov lub hom phiaj tsim kho.
Kev ua tiav thiab kev ua haujlwm ntawm qhov project tau muab kev txhawb nqa zoo rau kev txhim kho zoo ntawm Zhangjiakou Renewable Energy Demonstration Zone, uas tsis yog tsuas yog nce qhov feem ntawm lub zog huv zog noj hauv cheeb tsam Beijing-Tianjin-Hebei, tab sis kuj muab kev ruaj khov thiab huv zog muab kev txhawb nqa rau lub zog thov ntawm Beijing-Tianjin-Hebei load center.
