1. Taw qhia
Ib qho impulse voltage generator (feem ntau ua rau ntawm Marx generatortopology) yog ib qho ntawm cov khoom kim tshaj plaws thiab kev xav tau ntawm cov khoom siv hauv ib qho kev ntsuas siab -voltage test. Yuav qhov kev ntsuas tsis raug thiab koj yuav siv nyiaj pov tseg rau ntawm chav tsev tsis siv lossis, qhov phem dua, ua tsis tau raws li qhov yuav tsum tau ua ntawm IEC 60060 / GB / T 16927 rau koj cov khoom kuaj.
Phau ntawv qhia no taug kev los ntawm rau qhov kev txiav txim siab uas tseem ceeb thaum koj qhia lossis yuav qhov kev ntsuas qhov ntsuas hluav taws xob tsis zoo - kos los ntawm ntau tshaj kaum xyoo ntawm kev teeb tsa los ntawm 20 kV qhia chav mus txog 2400 kV UHV hom- kuaj tshuab.
2. Kauj Ruam 1 - Match Generator Voltage rau Koj Cov Khoom Siv Xeem BIL
Qhov feem ntau yuam kev yog sizing lub tshuab hluav taws xob mus rauntsuas qhov system voltagentawm cov khoom kuaj (piv txwv li . 35 kV), thaum koj xav tau qhov loj me rau qhov khoomBasic Insulation Level (BIL).
BIL yog lub zog hluav taws xob tiv thaiv hluav taws xob ib yam khoom yuav tsum muaj sia nyob, thiab nws ib txwm siab dua nws qhov ntsuas hluav taws xob:
| Ntsuas cov khoom ntsuas voltage | Hom BIL | Yam tsawg kawg nkaus generator voltage |
|---|---|---|
| 10 kV tsi | 75 - 95 kV | 200 kV ua |
| 3 5kv kwb | 200 kV ua | 400 kV ua |
| 66 kv ua | 325-350 kV | 600 kV ua |
| 110 kV TSI | 450-550 kV | 8 00kv |
| 220 kV TSI | 9 50kv | 1200 kV tsi |
Raws li txoj cai ntawm tus ntiv tes xoo, ntxiv ~ 20% headroom saum BIL kom suav rau lub tshuab hluav taws xob tsis muaj -load efficiency (feem ntau 85–90%) thiab waveform kam rau ua.
Yog tias koj tab tom sim faib-chav hloov pauv, bushings, surge arresters, switchgear lossis cables mus txog 35 kV chav kawm, a400 kV / 30 kV impulse voltage generatoryog tus qauv xaiv.
3. Kauj Ruam 2 - Loj Zog (kJ) mus rau Qhov Kev Ntsuas Qhov Ntsuas
Lub zog txiav txim siab seb koj puas tuaj yeem xa tag nrho cov ntsuas hluav taws xob mus rau hauv aloj, capacitive kuaj khoomtsis muaj lub waveform collapsing.
Rough guideline:
Hauv qab 2000 pF load(instrument transformers, me me bushings, MV switchgear): 10-30 kJ txaus.
2000-4000 pF load(fais fab transformers, GIS bays, ntev cable ntev): 30-60 kJ pom zoo.
Tshaj 4000 pF load(EHV fais fab transformers, lub tshuab hluav taws xob loj theem-nce units): 120 kJ thiab nce.
Cov chav kawm 400 kV / 30 kV tuav ntau dua lossis sib npaug li 90% kev siv hluav taws xob txog li 2000 pF load thiab Ntau dua lossis sib npaug li 85% txog 4000 pF - uas suav nrog feem ntau ntawm kev faib khoom-chav kawm apparatus.
Yog tias koj cov khoom sim ntsuas hnyav -duty 35 kV-chav transformers lossis reactors, nce mus rau400 kV / 60 kJversion es tsis dhau - qhia qhov voltage.
4. Kauj Ruam 3 - Koj Puas Yuav Tsum Tau Txiav -Wave Capability?
Tus qauv 1.2/50 µs puv -wave test stresseslongitudinal rwb thaiv tsevntawm windings. Atws yoj- terminated artificially ntawm 2–6 µs - ntxiv kev ntxhov siabinter-tig thiab inter-section rwb thaiv tsev, uas yog vim li cas lub hwj chim transformers thiab ntsuas transformers yuav luag ib txwm xav tau ob qho tib si.
Yog tias koj tus qauv xeem (IEC 60076-4 / GB 1094) hu rau chopped-wave tests, pob nyiaj siv rau ntau-gap chopping ntaus ntawv (feem ntau nyob ntawm 75% ntawm lub tshuab hluav taws xob voltage, xws li . 300} kV chopper ntawm 400 kV generator). Hla nws txhais tau tias koj tsis tuaj yeem ua tiav daim ntawv tshaj tawm hom kev xeem.
5. Kauj Ruam 4 - Roj-Pilled vs Qhuav-Hom Capacitor
Qhov no yog kev txiav txim siab ib puag ncig thiab kev saib xyuas, tsis yog kev ua haujlwm:
Roj-pulse capacitor puv: Tus nqi qis dua, muaj zog ntau dua, tab sis yuav tsum tau kuaj xyuas cov roj tsis tu ncua thiab tsis tsim nyog rau cov chav huv huv, chav kuaj sab hauv tsev nrog cov kev cai nruj nruj, lossis huab cua- tswj cov chaw tshawb fawb.
Qhuav- hom insulated capacitors: xoom roj to, ua haujlwm huv, me ntsis nqi tsev. Pom zoo rau thib peb- cov chaw kuaj mob, ib puag ncig hauv tsev kawm qib siab, thiab txhua qhov chaw uas muaj roj nchuav tsis tuaj yeem lees txais.
Ob hom tsim waveforms zoo tib yam - qhov kev xaiv yog hais txog yuav ua li cas koj xav khiav lub chaw.
6. Kauj Ruam 5 - Phau Ntawv Qhia, Semi- Tsis Siv Neeg, lossis Tsis Siv Neeg?
Phau ntawvNws yog qhov zoo rau R & D lab tua ob peb txhaj tshuaj ib hnub.
Semi- tsis siv neeg (PLC + phau ntawv txhais)yog qhov chaw qab zib rau feem ntau hom- kuaj pem teb - pib them, pib hauv av, tab sis tus neeg teb xov tooj nias hluav taws.
Tsis siv neeg puv(configurable shot count, interval time, auto-trigger and report export) them rau nws tus kheej thaum koj tab tom khiav ntau lawm batch los yog tas mus li kev ntsuam xyuas. Saib rau lub kaw lus uas khaws cov ntawv waveforms thiab xa tawm PDFs tau txais - phau ntawv nkag cov ntaub ntawv yog qhov uas tib neeg yuam kev nkag mus.
7. Kauj Ruam 6 - Npaj kom nthuav dav
Generators yog tsim los ntawm modular 100 kV theem. Tib qhov kev them nyiaj, tswj lub console thiab ntsuas cov saw uas tsav lub 4-theem (400 kV) chav tsev feem ntau tuaj yeem txuas ntxiv mus rau - qhov chaw mus rau 6, 8, 12 lossis 24 theem los ntawm kev ntxiv cov seem ntauwd - tsis muaj cov txheej txheem hauv paus.
Yog tias koj cia siab tias yuav sim siab dua - lub tshuab hluav taws xob hauv 5 xyoos, yuav qhov kev them nyiaj thiab kev tswj hwm ntawm cov kab ke loj dua hnub no thiab ntxiv ntau theem tom qab. Nws yuav luag ib txwm pheej yig dua li hloov tag nrho cov rig.
