Izintambo ze-Solar PVziyizingxenye ezibalulekile zanoma iyiphi isistimu ye-solar PV futhi zibonwa njengomzila wempilo oxhuma amaphaneli ngamanye ukuze enze uhlelo lusebenze.Amandla akhiqizwa ama-solar panel adluliselwa kwenye indawo okusho ukuthi sidinga izintambo zokudlulisa amandla avela kuma-solar panel - yilapho izintambo zelanga zingena khona.
Lo mhlahlandlela uzosebenza njengesiqondiso sesethulo sezintambo zelanga ezingu-4mm - izintambo zelanga okuyizona ezisetshenziswa kakhulu eduze kwezintambo ezingu-6mm.Sizohlukanisa umehluko phakathi kwezintambo/izintambo, izindlela zokulinganisa, nokufakwa kwekhebula lelanga elingu-4mm.
Izintambo Zelanga vs.Izintambo: Uyini Umehluko?
Amagama athi “intambo” kanye “nekhebula” kucatshangwa ukuthi ayafana emphakathini, kodwa empeleni kunomehluko omkhulu phakathi kwakho kokubili.Iphaneli yelanga iyiqembu lamakhondatha amaningi kuyilapho ucingo luyikhondatha eyodwa kuphela.
Lokhu kusho ukuthi izintambo empeleni ziyizingxenye ezincane ezakha ikhebula elikhulu.Ikhebuli yelanga engu-4mm inezintambo ezincane eziningi ngaphakathi kwekhebuli ezisetshenziselwa ukudlulisa ugesi phakathi kwamaphoyinti ahlukene ekusetheni ilanga.
Izintambo Zelanga: 4mm Isingeniso
Ukuze siqonde ukuthi izintambo zelanga ezingu-4mm zisebenza kanjani, kufanele sihlukanise izingxenye eziyisisekelo ezakha ikhebula: Izintambo.
Intambo ngayinye engaphakathi kwekhebula engu-4mm isebenza njengekhondatha futhi ikhebuli iqukethe amakhondatha anjalo amaningi.Izintambo zelanga zenziwe ngezinto eziqinile njengethusi noma i-aluminium.Lezi zinto zinikeza ukuxhumana okuthembekile kanye nekhono lokudlulisa ugesi kusuka kuma-solar panel ukuya ekhaya.
Kunezinhlobo ezimbili zezintambo: ucingo olulodwa kanye nocingo oluyimicu.Intambo eyodwa noma intambo eqinile isebenza njengekhondatha eyodwa ngaphakathi kwekhebula futhi ucingo ngokuvamile luvamise ukugqunywa ungqimba oluyisivikelo ukuze luvikeleke ezintweni.Izintambo ezizodwa zisetshenziselwa izintambo zikagesi eziyisisekelo ekhaya kuhlanganise nezintambo zelanga.Zivame ukuba yinketho eshibhile uma iqhathaniswa nezintambo eziboshiwe kodwa zingatholakala kuphela ngamageji amancane.
Izintambo eziboshiwe ziwumfowabo omkhulu wezintambo ezingazodwa futhi "ezihlanganisiwe" kusho ukuthi izintambo ziwukuxhuma kwezintambo ezihlukene eziphothwa ndawonye ukuze zenze ucingo olulodwa oluwumgogodla.Izintambo eziboshiwe zisetshenziswa ezinhlelweni zikanozungezilanga kodwa futhi zinezinye izinhlelo zokusebenza - ikakhulukazi izimoto ezihambayo njengezimoto, amaloli, ama-trailer, njll. Izintambo eziboshiwe zinenzuzo yokuba ziminyene futhi lokhu kuzenza zikwazi ukumelana nokudlidliza nezakhi, yingakho zinamandla. ibiza kakhulu.Izintambo eziningi zelanga ziza nezintambo eziboshiwe.
Iyini i-4mm Solar Cable?
Ikhebula lelanga elingu-4mm ikhebula eliwugqinsi elingu-4mm eliqukethe okungenani izintambo ezimbili ezimbozwe ndawonye ngaphansi kwekhava eyodwa yokuzivikela.Kuya ngomkhiqizi, ikhebuli engu-4mm ingaba nezintambo zamakhondatha ezi-4-5 ngaphakathi noma ingaba nezintambo ezi-2 kuphela.Ngokuvamile, izintambo zihlukaniswa ngokusekelwe enanini lezintambo zegeji.Kunezinhlobo ezahlukene zezintambo zelanga: Izintambo zezintambo zelanga, izintambo ze-solar DC, nezintambo ze-solar AC.
Izintambo zeSolar DC
Izintambo ze-DC yizintambo ezisetshenziswa kakhulu zokuhlanganisa izintambo zelanga.Lokhu kungenxa yokuthi i-DC current isetshenziswa ezindlini nasemaphaneli elanga.
- Kunezinhlobo ezimbili ezidumile zezintambo ze-DC: Izintambo ze-Modular DC nezintambo ze-DC zezintambo.
Zombili lezi zintambo zingahlanganiswa namaphaneli akho elanga le-PV futhi okudingayo nje isixhumi esincane ukuze uxhume izintambo ezahlukene ze-DC.Ngezansi sichaza indlela yokuxhuma izintambo zelanga ezingu-4mm usebenzisa izixhumi ezingathengwa kunoma yisiphi isitolo sezingxenyekazi zensimbi.
Ikhebula leSolar DC: 4mm
I-4mm DCikhebula le-pvingenye yezintambo ezisetshenziswa kakhulu ekuxhumeni i-solar.Uma ufuna ukuxhuma ikhebula lelanga elingu-4mm, ngokuyisisekelo kufanele uxhume izintambo eziphozithivu nezinegethivu ukusuka ezintanjeni ngokuqondile uye kusiguquli samandla elanga (ngezinye izikhathi okubizwa ngokuthi 'ibhokisi lejeneretha').Amandla okukhipha amamojula anquma intambo oyidingayo.Izintambo ezingu-4mm zisetshenziswa kuyilapho ezinye izinhlobo ezidumile ezifana nezintambo zelanga ezingu-6mm nezintambo zelanga ezingu-2.5mm zitholakala kuye ngezidingo zakho.
Amakhebuli elanga angu-4mm asetshenziswa kakhulu ngaphandle lapho ukukhanya kwelanga okunamandla kucwebezela kuwo, okusho ukuthi iningi lawo alikwazi ukumelana ne-UV.Ukuze uhlale uphephile kumasekhethi amafushane, uchwepheshe kufanele aqinisekise ukuthi awaxhumi izintambo eziphozithivu nezinegethivu kukhebula efanayo.
Ngisho nezintambo ze-DC ezinocingo olulodwa ziyasebenziseka futhi zinganikeza ukwethembeka okuphezulu.Ngokuya ngombala, uvamise ukuba nentambo ebomvu (ethwala ugesi) kanye nohlaza okwesibhakabhaka (negative charge).Lezi zintambo zizungezwe i-insulation panel ewugqinsi ukuze zivikeleke ekushiseni nasemvuleni.
Kungenzeka ukuxhuma i-intambo yelangaizintambo ku-inverter yamandla elanga ngezindlela eziningi.Okulandelayo izinketho zokuxhuma ezidume kakhulu:
- Indlela yeyunithi yezinhlamvu.
- Ibhokisi lokuhlanganisa le-DC.
- Ukuxhumana okuqondile.
- Ikhebuli yokuxhuma ye-AC.
Uma ufuna ukuxhuma usebenzisa intambo yokuxhuma i-AC, uzodinga ukusebenzisa okokuvikela ukuze uxhume iziguquli kugridi kagesi.Uma i-solar inverter iyisiguquli esinezigaba ezintathu, ukuxhumana okuningi kwe-voltage ephansi kwalolu hlobo kwenziwa kusetshenziswa izintambo ezinhlanu ze-AC.
Izintambo ezinhlanu ze-AC zinezintambo ezingu-3 zezigaba ezi-3 ezihlukene ezithwala ugesi: okulungile, okunegethivu, nokungathathi hlangothi.Uma unesistimu sonozungezilanga ene-inverter yesigaba esisodwa uzodinga amakhebuli angu-3 ukuze uyixhume: intambo ebukhoma, intambo yaphansi, nentambo emaphakathi.Amazwe ahlukene angase abe nemithetho yawo maqondana nokuxhumana nelanga.Hlola kabili ukuze uqinisekise ukuthi uthobela amakhodi endawo.
Ukulungiselela ukufakwa: Ungawasayizi Kanjani Amakhebula Elanga Kusistimu Yelanga
Ukulinganisa kungenye yezinto ezibaluleke kakhulu uma uxhuma izintambo ezahlukene ohlelweni lwe-PV.Ukulinganisa usayizi wezindaba ukuze uvikeleke ukuze ugweme ama-fuse amafushane kanye nokushisa ngokweqile lapho unamandla akhuphukayo - uma ikhebula ingakwazi ukuphatha amandla engeziwe, izoqhuma futhi lokhu kungabangela umlilo esimiso sonozungezilanga.Ngaso sonke isikhathi gibela phezu kwekhebula olidingayo ngoba ukuba nekhebula elincane kusho ukuthi usengozini yokudutshulwa futhi ushushiswe ngumthetho ngoba akukho emthethweni ezindaweni eziningi.
Nazi izinto eziyinhloko ezinquma usayizi odingekayo wekhebula lelanga:
- Amandla amaphaneli elanga (okungukuthi amandla okukhiqiza - uma unamanje amaningi, udinga usayizi omkhulu).
- Ibanga phakathi kwama-solar panel kanye nemithwalo (uma unebanga elikhulu phakathi kokubili, udinga ukumbozwa okuphezulu / usayizi ukuze uqinisekise ukudlula okuphephile).
I-Cable Cross-Sections Yekhebula Elikhulu Lelanga
Uma uxhuma iphaneli yelanga ngochungechunge (indlela edume kakhulu), iziguquli zakho kufanele zibe seduze nekhawunta yokuphakelayo ngangokunokwenzeka.Uma ama-inverters etholakala kude ne-cellar, ubude bekhebula lelanga bungabangela ukulahlekelwa okungaba khona ku-AC kanye nohlangothi lwe-DC.
Umongo lapha uwukuqinisekisa ukuthi ugesi okhiqizwa ama-solar panels uyakwazi ukufinyelela ngangokunokwenzeka ngaphandle kokulahlekelwa noma yikuphi ukuguqulwa kwe-solar inverter.Amakhebuli elanga anokumelana nokulahlekelwa uma esezingeni lokushisa elizungezile.
Ubukhulu bekhebula kukhebula lelanga le-DC eliyinhloko lingaba nomthelela ekuvimbeleni ukulahlekelwa noma ukugcina ukulahlekelwa kusezingeni elifanele - yingakho ikhebula elishubile, kuba ngcono nakakhulu.Abakhiqizi baklama izintambo zelanga ze-DC ngendlela yokuthi ukulahlekelwa kube kuncane kunokukhishwa okuphezulu kwejeneretha.Izintambo zelanga zinokumelana futhi ukwehla kwamandla kagesi kuleli phuzu lokumelana kungabalwa.
