Kev tsim kho ntawm UHV AC Transmission thiab Transformation Equipment

UHV series them nyiaj ntaus ntawv

Rau kev tsim kho loj ntawm ultra-high voltage tej yaam num, cov khoom siv tseem ceeb yog qhov tseem ceeb.

Txhawm rau txhawb kev txhim kho ntxiv ntawm UHV AC kis tau tus mob thev naus laus zis, kev tsim kho tshiab tshaj plaws ntawm cov cuab yeej tseem ceeb

xws li UHV AC transformer, roj insulated hlau enclosed switchgear (GIS), series them nyiaj ntaus ntawv thiab xob laim ntes yog

summarized thiab prospected.

Cov txiaj ntsig qhia tau tias:

Tus nqi tso cai ntawm lub zog hluav taws xob thaum qhov kev tso tawm ib nrab ntawm UHV transformer yog 1 ‰ yuav tsum raug xaiv raws li

tso cai teb zog;

Magnetic to tswj kev ntsuas xws li sib nqus shielding kawg ntawm lub cev, hluav taws xob tiv thaiv ntawm cov roj tank, sib nqus shielding

ntawm cov roj tank, thiab cov hlau tsis sib nqus hlau phaj tuaj yeem txo qhov sib nqus nqus thiab kub nce ntawm 1500 MVA

muaj peev xwm loj UHV transformer;

Lub peev xwm tawg ntawm UHV Circuit Court breaker tuaj yeem ncav cuag 63kA.Kev ntsuas hluav taws xob hluav taws xob raws li "peb txoj hauv kev" tuaj yeem tawg

los ntawm kev txwv ntawm cov khoom siv kuaj thiab ua kom tiav qhov kev xeem tawg ntawm 1100kV Circuit Court breaker;

Nws yog qhov tseeb tias qhov amplitude thiab zaus ntawm VFTO raug txwv los ntawm kev txhim kho damping resistors ntawm qhov chaw sib txuas ntawm "ntsej muag"

disconnectors;

Los ntawm qhov pom ntawm kev ua haujlwm tsis tu ncua, nws muaj kev nyab xeeb los txo qhov ntsuas hluav taws xob ntawm UHV ntes rau 780kV.

Lub neej yav tom ntej UHV AC fais fab kis tau tus mob thiab cov cuab yeej hloov pauv yuav tsum tau kawm tob txog kev ntseeg siab, muaj peev xwm loj,

tshiab ua hauj lwm hauv paus ntsiab lus thiab kev ua tau zoo parameter optimization.

UHV AC transformer, switchgear, series them nyiaj ntaus ntawv thiab xob laim ntes yog cov khoom tseem ceeb ntawm UHV AC kis tau tus mob

qhov project.Lub sijhawm no, peb yuav tsom mus rau kev txheeb xyuas thiab xaus qhov kev txhim kho thev naus laus zis tshiab ntawm plaub hom khoom siv no.

Kev tsim kho ntawm UHV series them nyiaj ntaus ntawv

UHV series them nyiaj ntaus ntawv tsuas yog daws cov teeb meem hauv qab no: kev cuam tshuam ntawm daim ntawv thov ntawm cov nyiaj them ua haujlwm rau

cov yam ntxwv ntawm lub cev, kev ua kom zoo ntawm qhov tseem ceeb ntawm cov txheej txheem ntawm cov nyiaj them poob haujlwm, muaj zog tiv thaiv electromagnetic

cuam ​​tshuam kev muaj peev xwm ntawm kev tswj, kev tiv thaiv thiab ntsuas qhov system, tsim thiab kev tiv thaiv ntawm lub txhab nyiaj super capacitor,
