Cov Chaw Saib Xyuas Cov Ntawv
Modular UPS with two-stage PFC: input PF>0.99, tag nrho cov tshuab efficiency mus txog 96%
Cov ntaub ntawv ntsuas: Tom qab kev hloov pauv ntawm PFC ntawm Chav Idc Computer, Tus Ntaus Transformer Siv tau nce los ntawm 27%
Chaw Ua Haujlwm Tshiab
Photovoltaic inverter: sib xyaw ua ke MPP thiab PFC dual - Ua haujlwm tswj, Txhim Kho Daim phiaj hloov kho
Charging pile system: Adopt totem pole PFC architecture, full load efficiency>97%
IV. Cov Ntsiab Lus Tseem Ceeb ntawm Kev Siv Kev Siv
Parameter txuam tsim qauv
Kev them nyiaj tau peev xwm kev xam: QC=p (tanqu 1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -}
Zam kev resonance point: configuring lim reactor nrog 7% reactance
Cov Khoom Siv Xaiv Tshwj Xeeb
Capacitcess unites: xaiv tus kheej - kho tau me me mets capacitor (withstand ac)
Sweet Ntaus: Gan ntaus ntawv yuav tsum tau hloov cov zaus ntau dua lossis sib npaug rau 100kHz
Cov ntsiab lus tseem ceeb ntawm kev sib xyaw ua ke
Cov qauv ua cua sov dissipation: yuam cua txias zog yuav tsum tau ntsib ΔT<30K
EMC kev kho: Teeb tsa X2 / Y2 Kev Nyab Xeeb Kev Nyab Xeeb los txhawm rau txhawm rau txhawm rau txhawm rau kev cuam tshuam
V. Kev Lag Luam Cov Nyiaj Tau Los rau Zog Kev Txhim Kho
Noj 10kV / 1000Kva fais fab xa tawm system ua piv txwv:
Cov tsis muaj ua ntej kho kom raug tom qab kho
Pf tus nqi 0.75 0.95
Kab poob 8% 5.2%
Lub Hlis Lub Zog Txuag - 21600 kwh
Peev Nyiaj Them Rov Qab - 14 lub hlis
VI. Kev loj hlob ntawm kev txiav-} ntug thev naus laus zis
