Hauv qhov xav tau ntawm high-voltage (HV) infrastructure, txheeb xyuas qhov tseeb thiab kev ruaj ntseg ntawm cov cuab yeej xws li Voltage Transformers (VT) thiab Capacitive Voltage Transformers (CVT) ntawm 400kV yog lub luag haujlwm tseem ceeb. Kev lig kev cai, kev sim ntawm cov qib no yuav tsum muaj cov khoom siv hauv chaw kuaj mob loj heev.
Txawm li cas los xij, nrog kev nce qib ntawm Series Resonance thev naus laus zis, 400kV kev sim tau tsiv tawm ntawm chav kuaj mus rau thaj chaw. Ntawm no yog qhov tob tob rau hauv cov kev cai thiab kev siv ntawm - tiam tom ntej 400kV / 1A AC Resonant Test System.
1. Kev qhia tshwj xeeb ntawm ib sab
Txhawm rau kom ua tau raws li cov qauv siv hluav taws xob thoob ntiaj teb (xws li IEC 61869), cov txheej txheem kev sim yuav tsum sib npaug ntawm cov khoom siv hluav taws xob loj nrog cov khoom siv nkag.
Kev tawm tswv yim Voltage: 230V AC, 50 Hz (ib theem) -Siv tau los ntawm tus qauv chaw fais fab lossis lub tshuab hluav taws xob portable.
Cov zis hluav taws xob: 400 kV AC, 50 Hz -Muaj peev xwm tuav EHV (Extra High Voltage) cov cuab tam kis tau tus mob.
Cov zis tam sim no: 1A -Muab tag nrho cov peev txheej ntawm 400 kVA.
Waveform: Ntshiab Sinusoidal (THD <1%) -Qhov tseem ceeb rau metrology thiab calibration raug.
2. The Core Technology: Yuav ua li cas 230V tsim 400kV
Qhov zais cia tom qab qhov kev txav mus los ntawm qhov system no yog Series Resonance Principple.
Los ntawm kev sib piv cov inductance (LL) ntawm lub kaw lus reactors nrog lub capacitance (CC) ntawm cov khoom kuaj (VT lossis CVT), lub kaw lus nkag mus rau lub xeev ntawm resonance ntawm 50 Hz.
Q-Qhov Zoo Tshaj Plaws: Hauv lub xeev resonant, lub kaw lus "amplifies" qhov voltage los ntawm qhov zoo ntawm 30 txog 80 (Qhov Zoo Tshaj Plaws).
Efficiency: Lub hwj huam mov tsuas yog yuav tsum tau muab lub zog "poob" xwb. Qhov no tso cai rau 230V ib zaug - theem tawm tswv yim los tsav lub zog loj 400kV tso tawm, tshem tawm qhov xav tau hnyav - lub luag haujlwm muaj zog hluav taws xob ntawm - qhov chaw.
3. High-Cov ntawv thov muaj nqis
A. Capacitive Voltage Transformers (CVT) Calibration
CVTs yog cov pob txha ntawm cov nyiaj tau los ntsuas thiab kev tiv thaiv hauv 400kV daim phiaj. Vim tias lawv yog cov capacitive, lawv yog cov neeg sib tw zoo tshaj plaws rau kev sim resonant. Peb lub kaw lus muab kev ruaj ntseg thiab zaus precision yuav tsum ntsuas qhov sib piv thiab theem yuam kev ntawm CVTs yam tsis muaj kev cuam tshuam ntau hauv "brute-force" transformers.
B. Gas-Insulated Switchgear (GIS/GSS) VT Testing
Kev sim VTs hauv ib puag ncig GIS yuav tsum muaj kev daws teeb meem vim qhov chaw txwv. Cov qauv tsim qauv ntawm peb cov Resonant Reactors tso cai rau qhov hloov pauv tau yooj yim, ua rau nws muaj peev xwm ua AC tiv taus thiab qhov tseeb ntawm GIS VTs txawm tias nyob hauv nroog loj substations.
C. Onsite High-Voltage Withstand Tests
Tshaj li calibration, 400kV 1A tso zis yog zoo tagnrho rau cov qauv AC Hipot kuaj. Nws txheeb xyuas qhov tsis muaj zog ntawm rwb thaiv tsev nyob rau hauv "Lub Xeem Mile" ntawm kev teeb tsa- kuaj pom kev puas tsuaj lossis kev sib dhos ua haujlwm uas lub Hoobkas kuaj tsis tuaj yeem ntes tau.
4. Vim li cas qhov tseeb thiab Waveform teeb meem
Rau lub hom phiaj calibration, 400kV cov zis yuav tsum "huv" li sai tau.
Harmonic Suppression: Lub resonant Circuit Court ua raws li lub ntuj qis- dhau lim, xa cov ntshiab 50Hz sine yoj. Qhov no ua kom ntseeg tau tias VT / CVT raug ntsuas raws li -kev ua haujlwm hauv ntiaj teb.
Zero-Voltage Start: Integrated controllers kom ntseeg tau tias qhov hluav taws xob nce siab los ntawm xoom, tiv thaiv cov cua ntsawj ntshab thib ob ntawm lub ntsuas hluav taws xob los ntawm cov hluav taws xob tam sim ntawd.
5. Tsav tsheb ROI rau cov chaw muab kev pabcuam kuaj
Rau EPC cov neeg cog lus thiab cov chaw kuaj sim, qhov kev txav mus los ntawm 400kV Series Resonance Test Set sawv cev rau qhov muaj txiaj ntsig zoo sib tw:
Txo Logistics: Modular Cheebtsam (hauv qab 60- 80} kg ib chav tsev) tuaj yeem thauj mus rau hauv tus qauv van.
Kev teeb tsa sai dua: Kev sib sau ceev ceev ntawm cov reactors tso cai rau "tib-hnub" kuaj thiab tshaj tawm.
Qib Metrology: Muab cov ntaub ntawv kev ntseeg siab xav tau los ua kom txaus siab rau kev soj ntsuam xyuas thiab kev xa khoom siv hluav taws xob.
