Thaum Lub Kaum Ob Hlis 23, Tianjin Dagang 500 kV kab txoj haujlwm tau ua tiav tiav.
Qhov project no nyob rau hauv Binhai Tshiab Thaj Chaw ntawm Tianjin City thiab yog ib qho ntawm cov kev tsim kho tseem ceeb ntawm "Top Ten Projects" hauv kev tsim kho kom zoo nkauj "Bincheng". Qhov project tau pib nrog 500 kV qauv ntawm 1, 000 kV Tianjin Nante High Voltage Station thiab xaus nrog tus tshiab No. 84 Ntauwd. Txoj kev ntev yog 2 × 35.11 kis lus mev, nrog 85 lub tsev tshiab, suav nrog 50 ob-circuit linear towers, 34 ob-circuit corner towers, thiab 1 ob-circuit davhlau ya nyob twg ntauwd, suav nrog 14 qhov tseem ceeb hla.
Thaum lub sijhawm ua tiav ntawm qhov project, ntau yam khoom siv hluav taws xob tau siv. Piv txwv li, lub transformer yog ntsia ntawm 500 kV qauv ntawm qhov chaw nres tsheb UHV thawj zaug los hloov high voltage mus rau qhov tsis tshua muaj hluav taws xob kom tau raws li qhov xav tau ntawm hluav taws xob. Kev rho tawm cov hloov pauv thiab cov khoom hloov pauv yog siv ntawm cov ncej yees kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub voj voog. Qhov twg tam sim no yuav tsum tau tswj, lub tshuab nqus tsev Circuit Court breakers los yog tso tawm fuses raug ntsia los txiav tawm tam sim no thaum tsim nyog. Tsis tas li ntawd, cov neeg tua hluav taws kuj raug ntsia rau ntawm qhov chaw tsim nyog los tiv thaiv kab los ntawm kev puas tsuaj ntuj xws li xob laim.
Nws tau tshaj tawm tias tom qab qhov project tau muab tso rau hauv kev ua haujlwm, nws yuav muab lub zog txhim khu kev qha rau cov haujlwm tseem ceeb xws li lub teb chaws tseem ceeb petrochemical project "Big Ethylene" hauv Tianjin Nangang Industrial Zone thiab LNG rau Beijing-Tianjin-Hebei roj. Los ntawm kev siv cov khoom siv hluav taws xob, qhov project no tau txhim kho lub zog tau txais lub peev xwm, muaj peev xwm kis tau tus mob thiab cov khoom siv hluav taws xob lav muaj peev xwm ntawm Tianjin Power Grid. Nyob rau tib lub sijhawm, qhov project no tseem ceeb heev hauv kev ua kom nrawm ntawm kev tsim kho ntawm 500 kV nthuav lub nplhaib network nyob rau sab qab teb sab hnub tuaj Tianjin, txhawb kev sib koom ua ke ntawm ntug dej hiav txwv cua rau hauv Tianjin 500 kV daim phiaj hluav taws xob hauv Nang's "14th Tsib Xyoo Plan", thiab txhawb kev sib koom ua ke thiab siv lub zog huv.
