Ukuqinisekisa ukhuseleko kunye nokusebenza: Isikhokelo kunxibelelwano lwe-DC-icala le-DC

Njengoko iinkqubo zokugcina amandla ekhaya ziya kuthandwa ngakumbi, kuqinisekisa ukhuseleko kunye nokusebenza kwe-wiring yazo, ngakumbi kwi-DC-icala le-DC, yinto enkulu. Uqhagamshelo oluthe ngqo (i-DC) phakathi kweephaneli zesolar, iibhetri, kunye namantshontsho afunekayo ekuguquleni amandla elanga kumbane onokusetyenziswa kwaye awuwugcinile ngokufanelekileyo. Esi sikhokelo sinika isishwankathelo sokuqwalaselwa okuphambili, iinkqubo ezilungileyo, kunye neempazamo eziqhelekileyo zokuthintela xa kuthelekiswa nokugcina i-DC-icala le-DC

Ukuqonda i-DC-icala le-interters yekhaya

I-DC-icala le-Inverter ye-Inverter kulapho kuhamba khona umbane ngqo kwi-solar kunye nebhanki ye-solar ngaphambi kokuba iguqulwe ibe yinye yokutshintsha kwangoku (AC) yokusetyenziswa kwekhaya. Eli cala lenkqubo libalulekile kuba liphatha ngokungqalileyo isizukulwana kunye nokugcinwa kwamandla.

Kwiseti yesiqhelo yelanga, iiphaphane zelanga zivelisa umbane we-DC, ohamba ngeentambo kunye nezinye izinto ukubiza iibhetri. Amandla agciniweyo kwiibhetri kukwimo yeDC. I-Inverter ke iguqula lo mbane we-DC wamandla o-AC ukubonelela ngezinto zombane zekhaya.

Izinto eziphambili ze-DC-icala zibandakanya:

Intambo ye-PV yelanga ehambisa umbane ukusuka kwiiphaneli ukuya kwi-inverter kunye nebhetri.
Izifundo eziqhagamshela iintambo kunye nezixhobo, ukuqinisekisa ukuhanjiswa kwamandla.
I-Fus kunye nokuguqula ukhuseleko, ukulawula kunye nokuxhobisa amandla njengoko kufuneka.

Ukuqwalaselwa kukhuseleko oluphambili kwi-DC-icala le-DC

Amanyathelo afanelekileyo okhuseleko osetyenziso lonxibelelwano lwe-DC lubalulekile ukuthintela iingozi zombane kwaye uqinisekise ukusebenza kwexesha elide. Nazi ezinye izinto eziphambili zokugcina engqondweni:

I-Incy yentambo kunye nokuBopha: Sebenzisa iintambo ezinokufakwa ngokufanelekileyo kuthintela ukuvuza kombane kwaye kunciphisa umngcipheko wesekethe emifutshane. Intambo yokusebenzisa intambo kufuneka ihambelane nomthwalo wangoku ukuthintela ukugqithisa kunye ne-voltage ihla, enokwenzakalisa ukusebenza kwenkqubo kwaye yenza umonakalo.

Ipomority echanekileyo: kwiinkqubo ze-DC, ukutshintsha kwakhona kwe-polarey kunokubangela ukungaphumeleli izixhobo okanye ukonakala. Ukuqinisekisa ukuba uqhagamshelo oluchanekileyo locingo lubalulekile ekuphepheni ukungasebenzi kakuhle.

Ukukhuselwa okungaphezulu Khusela inkqubo ngokusebenzisa i-fus kunye neesekethe zesekethe ezihambelana nokuhamba kwangoku kwi-wiring ye-DC.

Ukuphakama: Ukuqiniswa okufanelekileyo kokuqinisekisa ukuba nakuphi na ukuphazamiseka okukhoyo kubhekiswa ngokukhuselekileyo emhlabeni, ukunciphisa umngcipheko wothusi wombane nokuqinisekisa ukuzinza kwenkqubo. Izinto ezifunyayo ziyahluka lilizwe kodwa kufuneka zihlala zilandelwe ngokungqongqo.

Iindidi zeentambo ezisetyenziselwa uqhagamshelo lwe-DC

Ukukhetha i-carbs efanelekileyo yonxibelelwano lwe-DC lubalulekile kulo lonke ukhuseleko kunye nokusebenza. Ezinye iintlobo eziqhelekileyo zibandakanya:

I-SOLL PV ye-PV (H1z2z2-K, i-4703, i-TUV PV1-F) * Babonisa inqanaba eliphezulu lokuguquguquka, libenze balungele iinkqubo zamandla elanga.

Ukunyamezelana kobushushu obuphezulu: Iintambo ze-DC-Ecaleni kufuneka zikwazi ukumelana namaqondo obushushu aveliswe ngumbane ophumeleleyo ukusuka kwi-inverter ukuya kwi-inverter, ngakumbi ngexesha leeyure zokukhanya kwelanga.

Umgangatho oqinisekisiweyo: ukusebenzisa intambo eqinisekisiweyo iqinisekisa ukuthotyelwa kwemigangatho yokhuseleko kwaye inceda ukukhusela ukusilela kwenkqubo. Soloko ukhetha iintambo ezidibana ne-IEC, i-TUV, okanye imigangatho ye-UL.

Izenzo ezilungileyo zokufaka i-wiring ye-DC

Ukuqinisekisa ukhuseleko kunye nokuthembeka kwi-DC-icala le-DC, landela ezi ndlela zilungileyo:

Intambo inyibilika: Indlela efanelekileyo kwaye ikhuselekile i-DC ye-DC ukunciphisa ukubonakaliswa kweemeko zemozulu kunye nomonakalo womzimba. Kulumkele ukugoba okubukhali, okunokuphazamisa iintambo kwaye unobangela wangaphakathi ngokuhamba kwexesha.

Ukunciphisa i-voltage yehla: Ukugcina iintambo ze-DC ngokufutshane kangangoko kunokwenzeka kunciphise i-voltaged yehla, enokuthi inciphise ukusebenza kwenkqubo. Ukuba imigama emide ayinakuphepheka, yonyusa ubungakanani bekhebula ukubuyisela.

Sebenzisa izixhasi ezifanelekileyo: Qinisekisa ukuba amaKhaya ayongaphezulu kwemozulu kwaye ahambelana neentambo ezisetyenzisiweyo. Iziqhulo ezisemgangathweni ezisemgangathweni zinokubangela ilahleko yamandla okanye ingozi yomlilo.

Ukuhlolwa rhoqo kunye nolondolozo: Vavanya i-DC nge-DC rhoqo yokunxiba kunye nokukrazula, kubandakanya ukufakwa okuphathelele, uqhagamshelo olukhululekileyo, kunye neempawu zokungasebenzi. Ukulungiswa kwesiqhelo kunokuthintela imiba emincinci ukuba iguqukele kwiingxaki ezinkulu.

Iimpazamo eziqhelekileyo zokuphepha i-DC Wiring

Nokuba iinkqubo ezizenzelwe kakuhle zinokusilela ngenxa yeempazamo ezilula kwinkqubo yokufaka. Kunqande lo mjikelo uqhelekileyo:

Intambo engaphantsi okanye esezantsi-isebenzisa: ukusebenzisa iintambo ezincinci kakhulu komthwalo wangoku wenkqubo kunokukhokelela ekulahlekeni, ukulahleka kwamandla, kunye nemililo. Soloko ukhetha iintambo ezinokuthi ziphathe ngokupheleleyo iziphumo zakho zenkqubo yakho.

I-polay engalunganga: Ukubuyiswa kwakhona kwePolari kwiNkqubo ye-DC kunokubangela ukonakala kwizinto okanye ukusilela kwenkqubo. Jonga uqhagamshelo kabini ngaphambi kokuxhamla inkqubo.

I-birbs exineneyo: I-wiring exineneyo inokubangela iintambo ukuya kwicala elingaphezulu. Ukuqinisekiswa kwesithuba esifanelekileyo kunye nokufihlakeleyo, ngakumbi kwiindawo ezivaliweyo ezifana neebhokisi zejunction.

Ukutyeshela iikhowudi zasekhaya: Ummandla ngamnye unezikhowudi zogoso zombane, ezinje nge-NEC kwiMigangatho yase-US okanye ye-IEC yamazwe aphesheya. Ukusilela ukulandela oku kunokukhokelela ekungaphumeleli kwenkqubo okanye kwimicimbi yezomthetho.

Ukuthobela imigangatho yehlabathi kunye nemigaqo

Iinkqubo zokugcina amandla, kubandakanya ukudinwa kwe-DC-icala le-DC, kufuneka zihambelane nemigangatho eyahlukeneyo yamazwe aphesheya ukuqinisekisa ukusebenza okukhuselekileyo nenokuthenjwa:

IMigangatho ye-IEC: IKhomishini yeKhomishini yeZizwe zeZizwe zeMigangatho (IEC) ibonelela ngesikhokelo sehlabathi sokhuseleko lombane kunye nokusebenza.

IMigangatho ye-UL: IMigangatho yeLabhoratri ye-ALCRIes (il) isetyenziswe ngokubanzi eNyakatho Melika, inika isikhokelo malunga nokhuseleko lwemveliso kunye nesiqinisekiso.

I-NEC (Ikhowudi yoMbane kaZwelonke): I-NEC ibonelela ngemithetho nemigaqo yokufakelwa kombane e-US. Ukulandela isikhokelo se-NEC kuqinisekisa ukuthotyelwa kunye nokuthotyelwa.

Ukuthobela le migangatho ayikokuthi, Ihlala iyimfuneko kwimfuno yeinshurensi kwaye inokuchaphazela ukufaneleka kwenkqubo yenkuthazo kunye nezaphulelo.

Ukubeka iliso kunye nokugcina unxibelelwano lwe-DC-icala

Nditsho neenkqubo ezifakiweyo ezibalaseleyo zifuna ukubeka esweni rhoqo kunye nokugcinwa kwesondlo ukuze kuqinisekiswe ukusebenza kwe-PeAk. Nantsi indlela yokuhlala esebenza ngayo:

Ukuhlolwa rhoqo: Ishedyuli ye-Shedlic ijongeka kwi-Moures yomzimba, inxibe kunye nokukrazula, kunye nokunxibelelana okukhulu. Jonga iimpawu zokungasebenzi, ngakumbi kwizicwangciso zangaphandle.

Ukubeka iliso kwiNkqubo yokuBekwa kweliso: I-Anthers ezininzi ize neenkqubo zokubeka esweni ezivumela abasebenzisi ukuba balandele ukuveliswa kwamandla kunye nokusebenzisa. Izixhobo zokubeka iliso zinokukulumkisa iingxaki ezinjengelahleko yamandla ongalindelekanga, enokutyikitya umba wokudinisa.

Ukujongana nemicimbi ngokukhawuleza: Ukuba kukho naziphi na iimpawu zokunxiba okanye ukonakala kufunyanwa ngexesha lokuhlola, ukulungisa okanye ukutshintsha iindawo ezichaphazelekayo kwangoko. Inyathelo ngokukhawuleza linokuthintela imiba emincinci ukuba ingaphumeleli kulungiso lweendleko.

Ukuqukumbela

Ukhuseleko kunye nokusebenza kwe-interters yezamazama i-anthers ixhomekeke kakhulu kufakelo olufanelekileyo kunye nolondolozo lonxibelelwano lwe-DC. Ngeendlela ezilungileyo zokusebenzisa, ukusebenzisa izixhobo ezisemgangathweni eziphezulu, kunye nokulandela imigangatho yendawo, unokuqinisekisa inkqubo yokugcina ethembekileyo nenenjongo esebenzayo exhasa iimfuno zekhaya lakho. Soloko uqwalasela iingcali zokubonisana kwifreyimu entsokothileyo, ngakumbi xa ukuthotyelwa kwemigangatho yokhuseleko yehlabathi kuyafuneka.

Ngokulandela ezi ziKhokelo, awuyi kuphucula kuphela ukhuseleko lwakho kunye nokusebenza kwenkqubo yakho kodwa ukwandise ixesha lokuphila kunye nokwandisa imbuyekezo kutyalo-mali lwakho.
