Koj puas npaj yuav teeb tsa lub tshuab khaws hluav taws xob hauv tsev tab sis koj xav tias cov ntsiab lus ntawm kev siv tshuab nyuaj dhau lawm? Txij li cov inverters thiab cov roj teeb mus txog rau cov xov hlau thiab cov laug cam tiv thaiv, txhua yam khoom muaj lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ua haujlwm zoo thiab kev nyab xeeb. Cia peb piav qhia txog cov yam tseem ceeb uas yuav tsum xav txog thaum xaiv koj lub tshuab.
Kauj Ruam 1: Pib nrog Inverter
Lub inverter yog lub plawv ntawm koj lub kaw lus khaws cia hluav taws xob, hloov DC fais fab los ntawm roj teeb mus rau AC fais fab rau kev siv hauv tsev. Nwskev ntsuas hluav taws xobncaj qha cuam tshuam rau kev ua tau zoo thiab tus nqi. Txhawm rau txiav txim siab qhov loj me, xam koj liqhov xav tau hluav taws xob siab tshaj plaws.
Piv txwv li:
Yog tias koj siv lub qhov cub induction uas muaj zog 2000W thiab lub lauj kaub hluav taws xob 800W, tag nrho lub zog xav tau yog 2800W. Yog tias xav txog qhov ua tau ntau dhau ntawm cov lus qhia ntawm cov khoom, xaiv lub inverter uas muaj tsawg kawg yogMuaj peev xwm 3kW(lossis siab dua rau qhov kev nyab xeeb).
Qhov Input Voltage Tseem Ceeb:
Cov inverters ua haujlwm ntawm cov voltages tshwj xeeb (piv txwv li, 12V, 24V, 48V), uas qhia koj lub roj teeb lub voltage. Cov voltages siab dua (xws li 48V) txo qhov poob zog thaum lub sijhawm hloov pauv, txhim kho kev ua haujlwm zoo. Xaiv raws li koj lub cev qhov loj me thiab peev nyiaj.
Kauj Ruam 2: Xam Cov Kev Xav Tau ntawm Lub Txhab Nyiaj Roj Teeb
Thaum xaiv lub inverter lawm, tsim koj lub roj teeb. Rau lub kaw lus 48V, cov roj teeb lithium iron phosphate (LiFePO4) yog qhov kev xaiv nrov vim lawv muaj kev nyab xeeb thiab siv tau ntev. Lub roj teeb 48V LiFePO4 feem ntau muaj cov hauv qab no:16 lub hlwb hauv series(3.2V ib lub cell).
Tus Qauv Tseem Ceeb rau Qhov Kev Ntsuas Tam Sim No:
Yuav kom tsis txhob kub dhau, xam qhovqhov siab tshaj plaws ua haujlwm tam sim nosiv ob txoj kev:
1.Kev Xam Xam Raws Li Inverter:
Tam Sim No = Lub Hwj Chim Inverter (W) Lub Hwj Chim Tawm (V) × 1.2 (qhov kev nyab xeeb) Tam Sim No = Lub Hwj Chim Tawm (V) Lub Hwj Chim Inverter (W) × 1.2 (qhov kev nyab xeeb)
Rau 5000W inverter ntawm 48V:
500048 × 1.2 ≈125A485000×1.2 ≈125A
2.Kev Xam Xam Raws Li Cell (Kev Ceev Faj Dua):
Tam Sim No = Lub Hwj Chim Inverter (W) (Tus Naj Npawb Cell × Qhov Hluav Taws Xob Tsawg Tshaj Plaws) × 1.2 Tam Sim No = (Tus Naj Npawb Cell × Qhov Hluav Taws Xob Tsawg Tshaj Plaws) Lub Hwj Chim Inverter (W) × 1.2
Rau 16 lub hlwb ntawm 2.5V tso tawm:
5000 (16 × 2.5) × 1.2 ≈150A (16 × 2.5) 5000 × 1.2 ≈150A
Cov Lus Qhia:Siv txoj kev thib ob rau qhov muaj kev nyab xeeb siab dua.
Kauj Ruam 3: Xaiv Cov Khoom Siv Hluav Taws Xob thiab Kev Tiv Thaiv
Cov Cables thiab Busbars:
- Cov Cables Tso Tawm:Rau 150A tam sim no, siv 18 sq.mm tooj liab hlau (ntsuas ntawm 8A/mm²).
- Cov Txuas Txuas Inter-cell:Xaiv cov 25 sq.mm tooj liab-txhuas composite busbars (ntsuas ntawm 6A/mm²).
Pawg Neeg Tiv Thaiv (BMS):
Xaiv ib qho150A-rated roj teeb tswj system (BMS). Xyuas kom meej tias nws qhia meejmuaj peev xwm tam sim no tas mus li, tsis yog qhov siab tshaj plaws tam sim no. Rau ntau lub roj teeb teeb tsa, xaiv BMS nrogcov haujlwm txwv tam sim no sib luaglos yog ntxiv ib lub module sab nraud sib luag kom sib npaug cov loads.
Kauj Ruam 4: Cov Txheej Txheem Roj Teeb Sib Npaug
Kev khaws cia hluav taws xob hauv tsev feem ntau xav tau ntau lub roj teeb ua ke.cov modules sib luag uas tau ntawv pov thawjlos yog BMS nrog kev sib npaug ua ke kom tiv thaiv kev them / tso tawm tsis sib xws. Tsis txhob txuas cov roj teeb tsis sib xws kom ntev lub neej.
Cov Lus Qhia Kawg
- Ua qhov tseem ceebLiFePO4 hlwbrau kev nyab xeeb thiab lub neej voj voog.
- Xyuas kom tseeb tias muaj daim ntawv pov thawj (piv txwv li, UL, CE) rau txhua yam khoom.
- Tham nrog cov kws tshaj lij rau kev teeb tsa nyuaj.
Los ntawm kev sib dhos koj lub inverter, lub txhab roj teeb, thiab cov khoom tiv thaiv, koj yuav tsim kom muaj lub kaw lus khaws cia hluav taws xob hauv tsev uas txhim khu kev qha thiab ua haujlwm tau zoo.
