Qhov sib txawv tseem ceeb ntawm 5kVnruab nrab voltage cable, 15kV nruab nrab voltage cable, thiab 35kV mv cable lies nyob rau hauv lawv voltage theem thiab siv scenarios. cov
Ua ntej, nyob rau hauv cov nqe lus ntawm voltage, theem voltage ntawm 5kV nruab nrab voltage cable yog 5kV, voltage theem ntawm 15kV nruab nrab voltage cable yog 15kV, thiab voltage theem ntawm 35kV nruab nrab voltage cable yog 35kV. Lub ntsiab lus ntawm cov qib voltage no yog nyob ntawm qhov siab tshaj plaws voltage uas lub cable tuaj yeem tiv taus, thiab cov kab hluav taws xob sib txawv yog tsim rau cov kev xav tau sib txawv ntawm cov hluav taws xob sib txawv.
Qhov thib ob, los ntawm qhov kev xav ntawm cov xwm txheej, cov kab hluav taws xob nruab nrab feem ntau yog siv los xa cov hluav taws xob nruab nrab hluav taws xob, xws li cov kab xa tawm hauv cov phiaj xwm hauv nroog. 5kV nruab nrab voltage cables yog tsim rau kev faib tshuab nrog qis voltage yuav tsum, 15kV nruab nrab voltage cable yog haum rau tis systems nrog nruab nrab voltage yuav tsum, thiab 35kV nruab nrab voltage cable yog haum rau tis systems nrog ntau dua voltage yuav tsum tau. Kev xaiv ntawm cov cables no nyob ntawm qhov tshwj xeeb ntawm kev xa hluav taws xob thiab kev xa tawm, nrog rau cov qauv tsim thiab cov lus qhia tshwj xeeb ntawm lub kaw lus.
Thaum kawg, hais txog kev ua tau zoo thiab kev nyab xeeb, raws li qib voltage nce, cov ntaub ntawv rwb thaiv tsev thiab cov qauv tsim ntawm cables kuj yuav tsum tau ua kom yooj yim dua thiab txhim khu kev qha. Cov kab hluav taws xob siab (xws li 35kV nruab nrab voltage cable) yuav tsum muaj cov qauv kev nyab xeeb siab dua thiab kev sim nruj dua thaum tsim thiab tsim khoom kom ntseeg tau tias kev ua haujlwm ruaj khov hauv qhov chaw muaj hluav taws xob siab. Tsis tas li ntawd, cov kab hluav taws xob sib txawv muaj cov kev xav tau sib txawv rau kev teeb tsa thiab kev saib xyuas kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm qhov system
