This solution adopts a modular and platform-based design, and single-phase and three-phase share a development platform. Nws kov yeej qhov tsis txaus ntseeg ntawm tsuas yog ib qho kev sib xyaw ua ke, qhov yuav tsum tau rov ua dua tshiab thiab tsim kho cov khoom siv, thiab yuav tsum tau siv sijhawm ntev los txheeb xyuas qhov kev ntseeg tau thiab kev ruaj khov. Txoj kev daws teeb meem no muaj qhov tseem ceeb dua, mus txog 0.5s qib; Qhov yuam kev yog 50% ntawm theem 1 meter '. Nws muaj kev ncaj ncees zoo dua thiab cov tswv yim - zis rau cov tuam txhab fais fab. Qhov yuam kev xwm yeem yog qhov zoo dua thiab anti - sib xyaw ua ke muaj kev cuam tshuam. Nyob rau hauv ntau qhov kev cuam tshuam: suav nrog qhov kub thiab txias, feem ntau ua rau thaj chaw, thiab sib nqus, qhov yuam kev me me. Qhov siab tshaj plaws tam sim no tuaj yeem ncav cuag 200a.
2. Hluav taws xob Meter module
2.1 voltage diamond thiab voltage teeb liab piv txwv circuit Circuit Court module
Qhov hluav taws xob hluav taws xob hloov pauv sab nraud 220V cov ntsiab lus sib txawv rau hauv lub chaw nres nkoj ntawm SOF los ntawm V3P thiab v3n.
2.2 Lub transformer tam sim no tau teeb liab Sampling Circuit Court 1 module
Kev Siv Cov Ntsiab Cai: Sab Nrauv taw tes sab nraud dhau los ntawm cov paib hluav taws xob (R41
2.3 Hloov hluav taws xob tam sim no teeb liab Sampling Circuit 2 module
Kev siv cov hauv paus ntsiab lus: sab nraud taw qhia tam sim no los ntawm cov chaw nres nkoj tam sim no los ntawm cov cim hluav taws xob tam sim no los ntawm cov cim hluav taws xob tam sim no los ntawm kev tiv thaiv hluav taws xob tiv thaiv hluav taws xob. Ntawm lawv, R43 thiab R45 yog voltage dividers, R46 thiab R48 yog cov dividers dividers, thiab C49 ua si lub siab.
2.4 Lub Hwj Pwm Module
Lub zog hluav taws xob module muab ntau cov khoom siv hluav taws xob rau txhua qhov chaw ua haujlwm. Nws cov Circuit Court yog qhia hauv daim duab 5. Lub ntsiab hluav taws xob tau qhia los ntawm N thiab hloov mus rau qhov hluav taws xob ntawm txog 15v + dc_in los ntawm Circuit Court. Tom qab ntawd, tom qab tau ruaj khov los ntawm v3, MVDD tau muab rau analog zog thiab DVDD tau muab rau digital fais fab.
2.5 Mem Tes Rau Cov Ntaus Nrig Qauv
Kev ua haujlwm tshwj xeeb: Cov zis kos npe kos npe PIN ntawm lub ntsiab tswj tau raug cais tawm ntawm cov khoom siv kho kho tshiab los ntawm cov khoom siv kho kho kho tshiab thiab tawm rau ap1 thiab AP2. E1 yog lub luag haujlwm ntawm cov khoom siv kho kho kom raug kev rho tawm, thiab C24 yog lub luag haujlwm ntawm kev cuam tshuam thiab lim. AP1 thiab AP2 tuaj yeem sib txuas nrog ib lub rooj ntsuas hluav taws sab nraud kom ua tiav kev ua yuam kev thiab nrhiav kom pom.
Kev ua haujlwm tshwj xeeb: YCD tsav tsheb tsav nti tau txuas nrog cov pins tswj tau ntawm lub ntsiab tswj cov porns thiab lwm yam seg ntu ntu tswj. Cov zis tswj hwm ntu cov ntaub ntawv los tswj cov ntsiab lus saib ntawm LCD npo.
2.7 cia module
Cov ntaub ntawv cia module suav nrog cov chips cia rau hauv U2 thiab U3, lub khw twg thiab tswj cov ntaub ntawv xws li lub zog. Cov ntaub ntawv ntsuas hluav taws xob khaws cia hauv U2, thiab cov ntaub ntawv fais fab tau khaws cia hauv U3.
3. Meter Ua haum
Los ntawm cov qauv tsim qauv, lub ntsiab tseem ceeb thiab metering nti yog tib {} {{{1} {{{1} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {1} Lub network ntsuas uas yuav tsum tau pom tau tias twb npaj tau lawm rau pawg ntau lawm. Tsuas yog
Kev txiav tawm yuav tsum ua kom tiav cov zis tawm los ntawm cov qauv me me thiab cov tshuaj ntsuam me me me me. Kev ntsuas hluav taws xob yog cov tsim kev ua kom paub tab.
3.1 Hluav Taws Xob Hluav Taws Xob Kev Ua Haujlwm
Cov qauv tsim kho vajtse: Tus qauv tsim kho vajtse yog lub ntsuas metering nti thiab tswj lub ntsiab tswj tau txais kev txhawb nqa thiab lwm yam haujlwm. Ncaj qha txuas cov teeb liab analog rau peb lub analog cov tswv yim sib txawv ntawm lub ntsuas metering.
Software Tsim: Lub software tsim yog kom paub cov software ntau thiab kev tswj hwm cov ntaub ntawv ntawm cov ntaub ntawv ntsuas hauv lub metering module.
3.2 Kev muaj nuj nqi ntau tam sim no
Cov kev ntsuas lub siab tam sim no txhais tau tias lub ntsuas hluav taws xob tau muab tso rau hauv qhov hluav taws xob siab tam sim no yog 200A, vim hais tias lub siab tam sim no yog 200A
3.3 Kev Siv Hluav Taws Xob
Los ntawm kev ua kom sib haum ntawm cov hlua khi tshwj xeeb, ntu thiab kho vajtse,
Cov kev sib tw ua haujlwm ntawm ib qho -}} - xaim yog pom tau.
