Gis ib nrab tawm kuaj thiab sim hipot

Tus

AC wall withsttalis chatage kuaj Rau GIS yog cov txheej txheem tseem ceeb hauv kev ua haujlwm ntawm hluav taws xob engineering. GIS, uas sawv rau roj-insulated Switchgear, yog hom ntawm cov khoom siv hluav taws xob siab uas siv hluav taws xob ntau. Txhawm rau kom muaj kev cia siab thiab kev nyab xeeb ntawm GIS khoom, nws yog qhov tseem ceeb kom ua AC wallage ntsuas. AC withstand voltage ntsuas yog ua los ntawm kev thov cov cuab yeej hluav taws xob siab thiab ntsuas nws lub peev xwm los ua kom lub voltage tsis muaj tawg. Qhov kev ntsuas no yog qhov tseem ceeb thaum nws muaj cov khoom siv uas cov khoom siv tau thaum lub sijhawm ua haujlwm, xws li sortning surning lossis sur voltage loj.

Ntu kev tawm tsam (PD)Puas yog lwm qhov kev sim tseem ceeb heev rau cov roj-insulated Switchgear (GIS) cov tshuab los xyuas kom lawv txoj kev ntseeg tau thiab kev ntseeg tau. Kev txheeb xyuas qhov tshwm sim ib ntu yog qhov tshwm sim uas tuaj yeem tshwm sim hauv GIS lub tshuab vim yog cov rwb thaiv tsev tsis xws luag thiab tuaj yeem ua rau lub rwb thaiv tsev thiab, thaum kawg, ua tsis tiav ntawm lub system. Yog li ntawd, ua cov ntawv xeem PDD yog qhov tseem ceeb los kuaj xyuas qhov tsis xws luag thaum ntxov thiab tiv thaiv cov teeb meem muaj peev xwm nyob rau yav tom ntej.

Muaj ntau txoj hauv kev ntawm kev xeem PDD rau gis, suav nrog hluav taws xob, acoustic, thiab txoj kev kho qhov muag. Ib txoj kev ib txwm muaj yog cov qauv hluav taws xob, uas cuam tshuam nrog kev siv hluav taws xob rau GIS system thiab ntsuas ib qho kev tawm tsam uas yuav tshwm sim. Los ntawm kev txheeb xyuas cov ntaub ntawv sau los ntawm cov ntawv xeem no, cov kws ua choj tuaj yeem ntsuas qhov mob ntawm lub rwb thaiv tsev thiab txheeb xyuas qee qhov teeb meem uas yuav tsum tau daws.

Cov Khoom Kuaj

1. Tus qauv sib txawv heev Series Cov Kev Ntsuas Kuaj Syuam yog siv rau kev sim gis. Tus ua haujlwm ua haujlwm tau txais yuav los ua Circuit Court mus txog lub xeev resonant resonant lub xeev los ntawm kev kho cov zaus thiab txo lub hwj chim muaj peev xwm. Nws suav nrog cov khoom siv sib txawv ua kom muaj zog, muaj kev zam dhau los, cov reactor, thiab capital reactor, thiab hluav taws xob reactor, thiab hluav taws xob reactor, thiab hluav taws xob muaj zog.

2. Feem ntau rho tawm cov qauv siv thoob ntiaj teb thiab kev tswj hwm kev tswj hwm thiab tso tawm vaj huam sib luag kom kawm sai nrog kev kawm tsawg kawg. Ib qho ntxiv, cov ntsiab lus tshaj xws li yog qhov tseem ceeb dua, cov ntawv sau cia hauv calibration, cov ntaub ntawv tsom xam yog cov qauv. Nws muaj tag nrho cov kev pab cuam Ua raws li IEC {-270 Xws li daim ntawv qhia kev tso tawm ntawm PD kab ntawv, thiab lwm yam, ua rau nws tau yooj yim dua kom tau txais txiaj ntsig. Cov kev ntsuas tshiab digital thiab cuam tshuam nrog kev nplua nuj nrog kev nplua nuj thiab muaj kev txheeb xyuas cov qauv ntawm cov qauv. Txoj kev kuaj pom, ntsuas cov voj, thiab kev ua tau kev ua tau zoo ua raws li GB7354 thiab i {} "}"} "cov qauv kev ntsuas". Muaj feem rau txhua hom kev siv hluav taws xob ntau cov cuab yeej siv hluav taws xob, npog cov kev siv hluav taws xob tag nrho, rau qib ntawm cov cuab yeej siv digital PD tshuab ntawm cov thev naus laus zis ntau tshaj plaws

Tus Txheej Txheem Tseem Ceeb:

Ua ntej kev sim, kev npaj yuav tsum ua tiav los xyuas kom paub tseeb tias qhov kev ntsuas kev nyab xeeb thiab ua tau zoo

1. Xyuas kom cov gis installation thiab roj xwm txheej raws li qhov yuav tsum muaj.
2. Ua lwm yam kev ntsuas tsim nyog (piv txwv li, kev tawm tsam, noo noo, thiab xau dej).
3. Cov cuab yeej tsis koom nrog kev sim.
4. Npaj daim ntawv thov ntawm cov kev xeem voltage thiab ntsuas staging.
5. Kev ntsuas kev nyab xeeb, xws li kev tiv thaiv thiab kev tiv thaiv.

Cov kauj ruam tseem ceeb yog li hauv qab no;

1. Kev kho mob ua ntej: Thov 30% ntsuas voltage rau 5 feeb kom tshem tawm cov nqi them uas tseem tshuav
2. Theem Voltage Boost: Txhawb cov hluav taws xob los ntawm 25%, 50%, 75%, thiab 100%, thiab tuav txhua theem li 1 feeb
3. Cov kev soj ntsuam hauv zos hauv zos: ntawm 100% kev xeem voltage rau 30 feeb, khaws cia hauv zos tawm (tsawg dua lossis sib npaug)
