Intshayelelo: Ukunyuka kweBalcony PV kunye noMngeni woMbane oBuyayo
Utshintsho lwehlabathi oluya ekususeni icarbonization lukhuthaza utshintsho oluzolileyo kumandla okuhlala: iinkqubo ze-balcony photovoltaic (PV). Ukusuka "kwizityalo zamandla amancinci" kumakhaya aseYurophu ukuya kwiimarike ezisakhulayo kwihlabathi liphela, i-balcony PV inika abanini bezindlu amandla okuba ngabavelisi bamandla.
Nangona kunjalo, olu setyenziso lukhawulezileyo luzisa umngeni obalulekileyo kwezobuchwepheshe: ukubuyela umva kombane. Xa inkqubo ye-PV ivelisa umbane omninzi kunowo usetyenziswa yindlu, umbane ogqithisileyo unokubuyela kwigridi kawonke-wonke. Oku kunokubangela:
- Ukungazinzi kweGrid: Ukuguquguquka kweVoltha okuphazamisa umgangatho wamandla endawo.
- Iingozi zoKhuseleko: Iingozi kubasebenzi beenkonzo zombane abasenokungalindeli iisekethe ezibukhoma ezivela ngezantsi.
- Ukungathobeli imithetho: Iinkonzo ezininzi ziyakwalela okanye zihlawulisa ukungena okungagunyaziswanga kwigridi.
Kulapho isisombululo sokukhusela amandla esikrelekrele, esijikeleze isixhobo sokujonga esichanekileyo njengeZigBee Power Clamp, siba yinto ebalulekileyo kwinkqubo ekhuselekileyo, ethobelayo, nesebenzayo.
Isisombululo Esiphambili: Indlela Esebenza Ngayo Inkqubo Yokukhusela Amandla Abuyela Umva
Inkqubo yokukhusela amandla angasemva yiluphu ekrelekrele.Imitha yeZigBee Power Clampisebenza "njengamehlo," ngelixa isango elixhunyiweyo kunye nomlawuli we-inverter zenza "ubuchopho" obuthatha inyathelo.
Umgaqo Wokusebenza Ngamafutshane:
- Ukubeka esweni ngexesha langempela: I-power clamp, efana ne-PC321 model, isoloko ilinganisa indlela kunye nobukhulu bokuhamba kwamandla kwindawo yoqhagamshelo lwegridi ngesampulu yesantya esiphezulu. Ilandelela iiparameter eziphambili ezifana ne-Current (Irms), i-Voltage (Vrms), kunye ne-Active Power.
- Ukufumanisa: Kubona ngoko nangoko xa amandla eqala ukuhambaukusukaikhayatoigridi.
- Isignali kunye noLawulo: I-clamp ithumela le datha ngeprotocol yeZigBee HA 1.2 ukuya kwisango elihambelanayo ne-home automation okanye inkqubo yolawulo lwamandla. Emva koko inkqubo ithumela umyalelo kwi-PV inverter.
- Uhlengahlengiso lwaMandla: I-inverter inciphisa amandla ayo okukhupha ukuze ihambelane nokusetyenziswa kwekhaya ngoko nangoko, isusa naluphi na ujikelezo olubuyela umva.
Oku kudala inkqubo ethi "Akukho Kuthunyelwa Ngaphandle", ukuqinisekisa ukuba onke amandla elanga asetyenziswa apha ekhaya.
Iimpawu eziphambili ekufuneka uzijonge kwisisombululo sokujonga esikumgangatho ophezulu
Xa ukhetha isixhobo esiphambili sokujonga iiprojekthi zakho ze-PV zebhalkhoni, cinga ngezi mpawu zibalulekileyo zobugcisa ezisekelwe kubuchule beClamp yamandla yePC321.
Iinkcukacha zobugcisa ngokujonga nje:

|---|---|
| Iprotokholi engenazingcingo | I-ZigBee HA 1.2 - Ivumela ukuhlanganiswa okungenamthungo nokuhambelanayo kunye namaqonga amakhulu olawulo lwasekhaya olukrelekrele kunye namandla okulawula okuthembekileyo. |
| Ukuchaneka okulinganisiweyo | < ±1.8% yokufunda - Ibonelela ngedatha ethembekileyo ngokwaneleyo yokwenza izigqibo zolawulo ezichanekileyo kunye nokuqinisekisa ukuba akukho kuthunyelwa ngaphandle kwe-zero. |
| IiTransformers zangoku (CT) | Iinketho ze-75A/100A/200A, Ukuchaneka < ±2% - Iguquguqukayo kwiisayizi ezahlukeneyo zomthwalo. Ii-CT ezifakwe kwi-plug-in, ezinemibala zithintela iimpazamo zocingo kunye nexesha lokufakwa kwe-slash. |
| Ukuhambelana kweSigaba | Iinkqubo zesigaba esinye kunye nesesigaba esi-3 - Ziyasebenziseka kwiindawo ezahlukeneyo zokuhlala. Ukusetyenziswa kwee-CT ezi-3 zesigaba esinye kuvumela ukuphononongwa komthwalo ngokweenkcukacha. |
| IiParamitha eziPhambili eziLinganisiweyo | I-Current (Irms), iVoltage (iiVrms), Amandla asebenzayo kunye namandla, Amandla asebenzayo kunye namandla - Idatha epheleleyo yokuqonda nokulawula inkqubo epheleleyo. |
| Ukufakwa kunye noYilo | I-DIN-Rail encinci (86x86x37mm) - Igcina indawo kwiibhodi zokusasaza. Ilula (435g) kwaye kulula ukuyifaka. |
Ngaphaya kwePhepha leNgcaciso:
- Isignali Ethembekileyo: Ukhetho lwe-antenna yangaphandle luqinisekisa unxibelelwano oluqinileyo kwiindawo ezinzima zokufakela, nto leyo ibalulekileyo kwiluphu yokulawula ezinzileyo.
- Uvavanyo Olusebenzayo: Ukukwazi ukujonga iiparameter ezifana neReactive Power kunokunceda ekuchongeni impilo yenkqubo iyonke kunye nomgangatho wamandla.
Imibuzo Ebuzwa Rhoqo (FAQ) yeeNgcali
Umbuzo 1: Inkqubo yam isebenzisa iWi-Fi, hayi iZigBee. Ndingayisebenzisa na le nto?
A: I-PC321 yenzelwe i-ZigBee ecosystem, enika inethiwekhi ye-mesh ezinzileyo nenamandla aphantsi efanelekileyo kwizicelo zolawulo ezibalulekileyo ezifana nokukhusela amandla angasemva. Ukuhlanganiswa kufezekiswa ngesango elihambelana neZigBee, elinokuthi emva koko lidlulisele idatha kwiqonga lakho lefu.
Umbuzo 2: Inkqubo idibana njani ne-inverter ye-PV yokulawula?
A: I-power clamp ngokwayo ayilawuli ngqo i-inverter. Ibonelela ngedatha ebalulekileyo yexesha langempela kwi-logic controller (enokuba yinxalenye yesango lokuzenzekela kwekhaya okanye inkqubo yolawulo lwamandla ezinikeleyo). Le controller, xa ifumana isignali "yokuhamba kwamandla okubuyela umva" evela kwi-clamp, ithumela umyalelo ofanelekileyo "wokunciphisa" okanye "wokunciphisa isiphumo" kwi-inverter nge-interface yayo exhaswayo (umz., i-Modbus, i-HTTP API, unxibelelwano olomileyo).
Umbuzo 3: Ngaba ukuchaneka kwanele ukuhlawulisa iinkonzo ezisemthethweni?
A: Hayi. Esi sixhobo senzelwe ukujonga nokulawula amandla, kungekhona ukuhlawulisa ngexabiso leenkonzo. Ukuchaneka kwaso okuphezulu (<±1.8%) kugqibelele kwingqiqo yolawulo kwaye kubonelela ngedatha yokusetyenziswa ethembekileyo kakhulu kumsebenzisi, kodwa asinazo iziqinisekiso ezisemthethweni ze-MID okanye ze-ANSI C12.1 ezifunekayo ekulinganiseni ingeniso esemthethweni.
Q4: Iyintoni inkqubo yokufakela eqhelekileyo?
A:
- Ukufakela: Qinisekisa iyunithi ephambili kwireyile ye-DIN kwibhodi yokuhambisa.
- Ufakelo lwe-CT: Cima umbane kwinkqubo. Bopha ii-CT ezinemibala ejikeleze imigca ephambili yonikezelo lwegridi.
- Uqhagamshelo lweVolthi: Qhagamshela iyunithi kwivolthi yomgca.
- Ukuhlanganiswa kweNethiwekhi: Hlanganisa isixhobo nesango lakho leZigBee ukuze udibaniswe idatha kwaye usete ingqiqo yokulawula.
