Eposini lethu eledlule, sinikeze abafundi umhlahlandlela owusizo wamaphaneli elanga asekhaya.Lapha sizoqhubeka nale timu ngokukunikeza umhlahlandlela ohlukile wezintambo zelanga.
Izintambo zelanga, njengoba negama lisho, zingamapayipi okuhambisa ugesi.Uma umusha ezinhlelweni ze-PV, kubalulekile ukufunda okuyisisekelo.
Qhubeka ufunde ukuze ufunde kabanzi ngalolu hlobo lwekhebula, okuhlanganisa indlela esebenza ngayo, ukuthi isetshenziselwa ini, nokuthi ungayikhetha kanjani ikhebula elifanele.
Ikhebula lelanga kuhlelo lwe-photovoltaic
Uma nje ugesi usekhona, kufanele kube nezintambo namakhebuli.Amasistimu e-Photovoltaic awahlukile.
Izintambo nezintambo zidlala indima ebalulekile ekutholeni ukusebenza okuhle kakhulu ezinhlelweni zikagesi.Endabeni yezinhlelo ze-photovoltaic, isidingo sekhwalithi ephezulu yezintambo zelanga kanye nezintambo ziba kubaluleke kakhulu.
Amasistimu we-Photovoltaic aqukethe i-solar panel eyodwa noma ngaphezulu ahlanganiswe nama-inverters nezinye ihadiwe.Isebenzisa amandla elanga ukukhiqiza ugesi.
Ukuze uthole okuningi elangeni, isistimu ye-photovoltaic noma iphaneli yelanga idinga ukusebenza "iphelele" futhi ihlelekile.Enye yezingxenye ezibalulekile yikhebula lelanga.
Bayini?
Izintambo zelanga zenzelwe ukudlulisa amandla elanga e-DC ngokusebenzisa izinhlelo ze-photovoltaic.Asetshenziswa njengezintambo ezixhumanisayo zamaphaneli elanga kanye nama-photovoltaic arrays kugridi yelanga.
Zinamandla amakhulu emishini futhi zingamelana nezimo zezulu ezinzima.Emisebenzini yelanga, izintambo zelanga zibekwe kakhulu ngaphandle futhi zivezwe emazingeni okushisa aphezulu.
Phakathi nesikhathi sabo sokuphila eside esiyiminyaka engaba ngu-20 kuya kwengu-25, bangabhekana nezimo ezinzima.Ngakho-ke, kubalulekile ukuhlomisa isimiso sakho sonozungezilanga ngezintambo eziphezulu zelanga nezintambo.
Izintambo zelanga zihlukaniswa ngokusekelwe enanini lezintambo kanye nokucaciswa kwazo.Ngaphezu kwalokho, ububanzi bubuye buncike kwinani lezintambo kanye nokucaciswa kwazo.
Ngokuvamile, kunezinhlobo ezintathu zezintambo zelanga ezisetshenziswa ezinhlelweni ze-photovoltaic:
Dc ikhebula lelanga
Ikhebula elikhulu le-Solar DC
Ikhebula le-solar ac
Izinhlobo zekhebula lelanga
Emisebenzini yamandla elanga, izinhlobo ezahlukene zezintambo ziyadingeka ukuze kwenziwe umsebenzi.Zombili izintambo ze-DC ne-AC zingasetshenziswa.
Iphaneli ye-photovoltaic kanye ne-inverter, kuhlanganise nebhokisi le-junction, ixhunywe ngekhebula le-DC.Ngesikhathi esifanayo, i-inverter kanye nesiteshi esincane sixhunywe ngekhebula le-AC.
1. Dc ikhebula lelanga
Izintambo ze-solar ze-Dc ziyizintambo zethusi ezinomgogodla owodwa ezine-insulation kanye ne-sheathed.Zisetshenziswa ngaphakathi kwamaphaneli elanga e-photovoltaic futhi zingaba izintambo zemojula noma izintambo zezintambo.
Ngaphezu kwalokho, ziza nezixhumi ezifanele futhi zakhiwe ngaphambili kuphaneli.Ngakho-ke, ngeke ukwazi ukuwashintsha.
Kwezinye izimo, uzodinga intambo yezintambo zelanga ze-DC ukuze uyixhume kwamanye amaphaneli.
2. Ikhebula elikhulu le-solar DC
Ikhebula le-DC eliyinhloko yikhebula elikhulu lokuqoqa amandla.Baxhuma ibhokisi le-generator junction kuzintambo ezinhle nezimbi ze-inverter ephakathi.
Ngaphezu kwalokho, zingaba izintambo eziwumgogodla owodwa noma ezimbili.I-Single core wire ene-double insulation iyisixazululo esisebenzayo sokuhlinzeka ngokuthembeka okuphezulu.Ngesikhathi esifanayo, ukuxhumana phakathi kwe-solar inverter kanye nebhokisi le-generator junction, ukusetshenziswa okungcono kakhulu kwe-dual-core DC cable.
Ochwepheshe ngokuvamile bakhetha ukufakwa ngaphandle kwezintambo ezinkulu ze-solar DC.Osayizi bavamise ukuba ngu-2mm, 4mm no-6mm.
Qaphela: Ukuze ugweme izinkinga ezifana nokujikeleza okufushane kanye nokubeka phansi, kunconywa ukuthi amakhebuli ane-polarity ephambene ahanjiswe ngokuhlukana.
3. Ikhebula le-Ac
Izintambo ze-Ac zixhuma isiguquli selanga kuzinto zokuvikela kanye negridi yamandla.Kuzinhlelo ezincane ze-PV ezinama-inverter ezigaba ezintathu, ikhebula le-AC elinezisekelo ezinhlanu lisetshenziselwa ukuxhuma kugridi.
Ukusatshalaliswa kwezintambo kanje:
Izintambo ezintathu ezibukhoma,
Intambo yaphansi eyodwa kanye nentambo eyodwa engathathi hlangothi.
Ithiphu: Uma isistimu yakho ye-PV ine-inverter yesigaba esisodwa, sebenzisa ikhebuli ye-AC yamacore amathathu.
Ukubaluleka kwekhebula lelanga kumaphrojekthi we-PV
Njengoba kushiwo ngaphambili, izintambo zelanga zidlulisela amandla elanga e-DC ukusuka kwenye ingxenye yedivayisi ye-photovoltaic kuya kwenye.Ukuphathwa kwekhebula ngendlela efanele kubalulekile uma kuziwa ekuphepheni nasekuphileni isikhathi eside kwesistimu ngayinye ye-PV.
Ukufakwa kwezintambo kumaphrojekthi welanga kungaphansi kwemisebe ye-ultraviolet, amazinga okushisa aphezulu kanye nomswakama womoya.Bangakwazi ukumelana nezidingo ezinzima zezinhlelo ze-photovoltaic - kokubili ngaphakathi nangaphandle.
Ngaphezu kwalokho, lezi zintambo azinamandla kuphela, kodwa futhi ziphikisana nesimo sezulu.Bangakwazi ukumelana nokucindezeleka okuvela ekucindezelweni, ukugoba noma ukwelula, kanye nokucindezeleka kwamakhemikhali ngendlela:
Khetha intambo yelanga elungile yohlelo lwakho lwe-PV
Amakhebuli elanga kufanele anele izinhlelo zokusebenza zesistimu ye-PV efunwa kakhulu.Khetha imodeli enokumelana okuphezulu kakhulu nezinselele zomkhathi njenge-UV, i-ozone, nomswakama.
Akugcinanga lapho, kodwa ikhebula kufanele likwazi ukumelana namazinga okushisa aqinile (-40°C kuya ku-120°C).Kukhona ukuguga, umthelela, ukudabuka kanye nengcindezi.
Isinyathelo esisodwa ngaphezulu, uhlobo olulungile lwelanga
