Kunoma iyiphi iphrojekthi yelanga, udinga intambo yelanga ukuze uhlanganise i-hardware yelanga.Izinhlelo eziningi zephaneli yelanga zihlanganisa izintambo eziyisisekelo, kodwa ngezinye izikhathi kufanele uthenge izintambo ngokuzimela.Lo mhlahlandlela uzohlanganisa izinto eziyisisekelo zezintambo zelanga ngenkathi ugcizelela ukubaluleka kwalezi zintambo kunoma yisiphi isimiso selanga esisebenzayo.

Ikhebula lelanga, ngezinye izikhathi elaziwa ngokuthi 'PV Wire' noma 'PV Cable' iyikhebula elibaluleke kakhulu kunoma iyiphi isistimu yelanga ye-PV.Amaphaneli elanga akhiqiza ugesi okufanele udluliselwe kwenye indawo - kulapho izintambo zelanga zingena khona. Umehluko omkhulu ngosayizi uphakathi kwentambo yelanga engu-4mm nentambo yelanga engu-6mm.Lo mhlahlandlela uzofaka amanani amaphakathi ezintambo kanye nendlela yokubala ukuthi ungakanani usayizi owudingayo ekusetheni kwakho ilanga.

Isingeniso Sezintambo Zelanga

Ukuze uqonde ukuthi kanjaniizintambo zelangaumsebenzi, kufanele sifinyelele ekusebenzeni okuyinhloko kwekhebula: Intambo.Nakuba abantu becabanga ukuthi izintambo nezintambo ziyizinto ezifanayo, la magama ahluke ngokuphelele.Izintambo zelanga ziyizingxenye ezilodwa, ezaziwa ngokuthi 'amakhondatha'.Izintambo zelanga zingamaqembu ezintambo/amakhondatha ahlanganiswe ndawonye.

Empeleni, uma uthenga ikhebula lelanga uthenga intambo enezintambo eziningi ezazixhunywe ndawonye ukuze zenze ikhebula.Izintambo zelanga zingaba nezintambo ezi-2 ezincane kanye nezintambo eziningi, kuye ngosayizi.Zithengeka kahle futhi zithengiswa ngonyawo.Isilinganiso senani lekhebula lelanga ngu-$100 nge-spool ngayinye engu-300 ft.

Zisebenza Kanjani Izintambo Zelanga?

I-solar wire ngokuvamile yenziwa kusukela ku-conductive material engadlulisela ugesi njengethusi.I-Copper iyinto ethandwa kakhulu yezintambo zelanga, futhi ngezinye izikhathi izintambo zenziwe nge-aluminium.Intambo yelanga ngayinye iyikhondatha eyodwa ezisebenza yona yodwa.Ukwandisa ukusebenza kahle kwesistimu yekhebula, izintambo eziningi zihlanganiswa ndawonye.

Intambo yelanga ingaba eqinile (ibonakale) noma ifakwe into ebizwa ngokuthi 'ijakhethi' (ungqimba oluvikelayo olulwenza lungabonakali).Ngokwezinhlobo zezintambo, kunezintambo ezilodwa noma eziqinile.Zombili lezi zisetshenziselwa izinhlelo zokusebenza zelanga.Kodwa-ke, izintambo ezinezintambo yizona ezivame kakhulu ngoba zakhiwe amasethi ezintambo eziningi ezincane ezisonte ndawonye ukuze zakhe umnyombo wocingo.Izintambo ezi-Smellier single zitholakala kuphela kumageji amancane.

Izintambo ezinezintambo ziyizintambo ezivame kakhulu zezintambo ze-PV ngoba zinikeza izinga eliphezulu lokuzinza.Lokhu kulondoloza ubuqotho besakhiwo bentambo uma kuziwa kungcindezi evela ekudlidlizeni nokunye ukunyakaza.Isibonelo, uma izinyoni zinyakazisa izintambo noma ziqala ukuhlafuna phezu kophahla lapho kukhona ama-solar panel, udinga ukuvikeleka okwengeziwe ukuze uqinisekise ukuthi ugesi uzoqhubeka nokugeleza.

Ayini Amakhebula e-PV?

Izintambo zelanga ziyizintambo ezinkulu ezihlanganisa izintambo eziningi ngaphansi 'kwejakhethi' eyisivikelo.Kuye ngesistimu yelanga, uzodinga ikhebula elihlukile.Kungenzeka ukuthenga ikhebula lelanga elingu-4mm noma ikhebula lelanga elingu-6mm elizoba mkhulu futhi linikeze ukudluliswa kwamandla kagesi aphezulu.Kuphinde kube nomehluko omncane ezinhlotsheni zekhebula le-PV njengezintambo ze-DC nezintambo ze-AC.

Indlela Yokulinganisa Izintambo Zelanga: Isingeniso

Okulandelayo yisingeniso sokulungisa usayizi kanye namagama.Okokuqala, usayizi ovame kakhulu wezintambo zelanga yi-“AWG” noma i-'American Wire Gauge'.Uma une-AWG ephansi, lokhu kusho ukuthi ihlanganisa indawo enkulu ephambanayo ngakho-ke inokwehla kwamandla kagesi aphansi.Umkhiqizi wephaneli yelanga uzokunikeza amashadi abonisa ukuthi ungaxhuma kanjani amasekhethi ayisisekelo e-DC/AC.Uzodinga ulwazi olubonisa inani eliphezulu lamanje elivunyelwe endaweni ehlukanisayo yesistimu sonozungezilanga, ukwehla kwamandla kagesi, kanye ne-DVI.

Ubukhulu bekhebula lephaneli yelanga elisetshenzisiwe libalulekile.Ubukhulu bekhebula bungathinta ukusebenza kwawo wonke isimiso sonozungezilanga.Uma uthenga ikhebuli encane kunaleyo enconywe umkhiqizi wakho welanga, ungathola ukwehla okukhulu kwamandla kagesi ezintanjeni okuholela ekulahlekeni kwamandla.Ngaphezu kwalokho, uma unezintambo ezincane lokhu kungaholela ekukhuphukeni kwamandla okuholela emlilweni.Uma kuqubuka umlilo ezindaweni ezinjengophahla, ungasakazekela endlini yonke.

Indlela Amakhebula e-PV Alinganiswa Ngayo: I-AWG Meaning

Ukukhombisa ukubaluleka kosayizi wekhebula le-PV, cabanga ngentambo efana nepayipi elithwala amanzi.Uma unobubanzi obukhulu epayipini, amanzi azogeleza kalula futhi ngeke amelane nanoma yikuphi.Kodwa-ke, uma unepayipi elincane uzobhekana nokumelana njengoba amanzi engakwazi ukugeleza kahle.Ubude bubuye bube nomthelela - uma une-hose emfushane, ukugeleza kwamanzi kuzoshesha.Uma une hose enkulu, udinga ukucindezela okulungile noma ukugeleza kwamanzi kuzokwehla.Zonke izintambo zikagesi zisebenza ngendlela efanayo.Uma unekhebula le-PV elingelikhulu ngokwanele ukusekela iphaneli yelanga, ukumelana kungabangela ukuthi ama-watts ambalwa adluliselwe futhi avimbe isifunda.

Izintambo ze-PV zilinganiswa kusetshenziswa ama-American Wire Gauges ukuze kulinganiswe isikali segeji.Uma unocingo olunenombolo yegeji encane (AWG), uzoba nokumelana okuncane futhi ogelezayo kusuka kumaphaneli elanga uzofika ngokuphepha.Amakhebuli e-PV ahlukene anosayizi abahlukene begeji, futhi lokhu kungase kuthinte intengo yekhebula.Usayizi ngamunye wegeji unesilinganiso sawo se-AMP okuyinani eliphakeme lama-AMPs angahamba ngekhebuli ngokuphephile.

Ikhebula ngalinye lingamukela kuphela inani elithile le-amperage ne-voltage.Ngokuhlaziya amashadi ezintambo, kufanele ukwazi ukunquma ukuthi ungakanani usayizi ofanele wesistimu yakho sonozungezilanga (uma lokhu kungafakwanga kubhukwana).Uzodinga izintambo ezahlukene ukuze uxhume ama-solar panel ku-inverter eyinhloko, bese ufaka i-inverter kumabhethri, amabhethri ebhange lebhethri, kanye / noma i-inverter ngqo kugridi kagesi yendlu.Okulandelayo ifomula eklanyelwe ukukusiza wenze izibalo:

1) Linganisa i-VDI (I-Voltage Drop)

Ukuze ubale i-VDI yesistimu sonozungezilanga, uzodinga ulwazi olulandelayo (olunikezwe umkhiqizi wakho):

· Isamba se-amperage (ugesi).

· Ubude bekhebula ngendlela eyodwa (kukalwa ngezinyawo).

· Amaphesenti okwehla kwamandla kagesi.

Sebenzisa le fomula ukulinganisa i-VDI:

· I-Amperage x Izinyawo / % yokwehla kwamandla kagesi.

2) Nquma usayizi ngokusekelwe ku-VDI

Ukuze ubale ukuthi ungakanani usayizi owudingayo kukhebula ngalinye lohlelo, udinga i-VDI.Ishadi elilandelayo lizokusiza ukuthi uthole usayizi owudingayo wohlelo lokusebenza:

I-Voltage Drop Index Gauge

62 = # 2/0

78 = #3/0

99 =# 4/0

Isibonelo: Uma unama-AMPs angu-10, amafithi angu-100 ebanga, iphaneli engu-24V, kanye nokulahlekelwa okungu-2% ugcina unesibalo esingu-20.83.Lokhu kusho ukuthi ikhebuli oyidingayo yikhebuli engu-4 AWG.

PV Solar Cable Osayizi & Izinhlobo

Kunezinhlobo ezimbili zezintambo zelanga: izintambo ze-AC kanye nezintambo ze-DC.Izintambo ze-DC ziyizintambo ezibaluleke kakhulu ngoba ugesi esiwusebenzisa kumasistimu elanga nesiwusebenzisa ekhaya ugesi we-DC.Amasistimu elanga amaningi afika nezintambo ze-DC ezingahlanganiswa nezixhumi ezanele.Izintambo ze-solar DC nazo zingathengwa ngqo ku-ZW Cable.Osayizi abadume kakhulu bezintambo ze-DC yi-2.5mm,4mm, futhi6mmizintambo.

Kuye ngobukhulu besistimu yelanga kanye nogesi okhiqizwayo, ungase udinge ikhebula elikhulu noma elincane.Iningi lamasistimu elanga e-US lisebenzisa intambo ye-PV engu-4mm.Ukuze ufake lezi zintambo ngempumelelo, kufanele uxhume izintambo ezingezinhle nezilungile ezintanjeni ezisebhokisini lesixhumi eliyinhloko elihlinzekwa ngumkhiqizi welanga.Cishe zonke izintambo ze-DC zisetshenziswa ezindaweni ezingaphandle njengophahla lwendlu noma kwezinye izindawo lapho kubekwa khona amaphaneli elanga.Ukuze ugweme izingozi, izintambo ze-PV ezinhle nezingezinhle ziyahlukaniswa.

Ungawaxhuma Kanjani Amakhebula Elanga?

Kunezintambo ezingu-2 kuphela ezidingekayo ukuze kuxhunywe isistimu yelanga.Okokuqala, udinga ikhebula elibomvu okuvamise ukuba yikhebula eliphozithivu ukuthwala ugesi kanye nentambo eluhlaza okwesibhakabhaka enegethivu.Lezi zintambo zixhuma ebhokisini le-generator eliyinhloko lesistimu yelanga kanye ne-solar inverter.Izintambo ezincane ezinocingo olulodwa zingasebenza kahle ekudluliseleni amandla inqobo nje uma zisongwe ngokufakelwa.

Izintambo ze-AC nazo zisetshenziswa ezinhlelweni zelanga, kodwa kancane kancane.Izintambo eziningi ze-AC zisetshenziselwa ukuxhuma isiguquli selanga esiyinhloko kugridi kagesi yasekhaya.Amasistimu elanga asebenzisa amakhebuli angu-5-core AC anezintambo ezingu-3 zezigaba ezithwala i-current, intambo engu-1 ukuze igcine i-current kude nedivayisi, kanye nentambo engu-1 yokubeka phansi/ukuphepha exhuma isikhwama selanga nomhlaba.

Ngokuya ngosayizi wesimiso sonozungezilanga, kungase kudinge izintambo ezingu-3-core kuphela.Kodwa-ke, lokhu akufani neze kulo lonke ibhodi ngoba izifundazwe ezahlukene zisebenzisa imithetho ehlukene okufanele ilandelwe ochwepheshe abafaka izintambo.
