Amandla amasha ahlanzekile, njengamandla e-photovoltaic namandla omoya, afunwa umhlaba wonke ngenxa yezindleko zawo eziphansi kanye nokuluhlaza. Enqubweni yezingxenye zesiteshi sikagesi se-PV, izintambo ezikhethekile ze-PV ziyadingeka ukuze kuxhunywe izingxenye ze-PV. Ngemva kweminyaka yokuthuthuka, imakethe yasekhaya yesiteshi samandla e-photovoltaic isibe ngempumelelo ngaphezu kwama-40% okukhiqizwa kwamandla kagesi we-photovoltaic emhlabeni. Ngakho yiziphi izinhlobo zemigqa ye-PV evame ukusetshenziswa? UXiaobian uhlele ngokucophelela izindinganiso zekhebula le-PV zamanje namamodeli avamile emhlabeni jikelele.
Okokuqala, imakethe yaseYurophu idinga ukuphasisa isitifiketi se-TUV. Imodeli yayo yi-pv1-f. ukucaciswa kwalolu hlobo lwekhebula ngokuvamile kuphakathi kuka-1.5 no-35 mm2. Ngaphezu kwalokho, inguqulo ethuthukisiwe yemodeli ye-h1z2z2 inganikeza ukusebenza okunamandla kagesi. Okwesibili, imakethe yaseMelika idinga ukuphasisa isitifiketi se-UL. Igama lesiNgisi eliphelele lalesi sitifiketi liyasebenziseka. Ukucaciswa kwezintambo ze-photovoltaic ezidlula isitifiketi se-UL ngokuvamile zingaphakathi kwebanga le-18-2awg.
Inhloso ukudlulisa i-current. Umehluko wukuthi izidingo zendawo yokusetshenziswa zihlukile uma udlulisa okwamanje, ngakho-ke izinto zokwakha kanye nezinqubo ezakha ikhebula zihlukile.
Amamodeli wekhebula elivamile le-photovoltaic: PV1-F, H1Z2Z2-K, 62930IEC131, njll.
Amamodeli wekhebula avamile: i-RV, BV, BVR, YJV, VV nezinye izintambo eziwumgogodla owodwa.
Umehluko ezidingweni zokusetshenziswa:
1. Ama-voltage akalwe ahlukene
Intambo ye-PV: 600/100V noma 1000/1500V yezinga elisha.
Ikhebuli evamile: 300/500V noma 450/750V noma 600/1000V (uchungechunge lwe-YJV/VV).
2. Ukuguquguquka okuhlukile kwemvelo
Intambo ye-Photovoltaic: Kudingeka ukuthi imelane nezinga lokushisa eliphezulu, ukubanda, amafutha, i-asidi, i-alkali, imvula, i-ultraviolet, i-flame retardant kanye nokuvikelwa kwemvelo. Ingasetshenziswa esimweni sezulu esibi ngempilo yesevisi engaphezu kweminyaka engama-25.
Ikhebula elivamile: ngokuvamile lisetshenziselwa ukubeka endlini, ukubeka amapayipi angaphansi komhlaba kanye noxhumo lwempahla kagesi, linokushisa okuthile nokumelana nowoyela, kodwa ayikwazi ukuvezwa ngaphandle noma ezindaweni ezinokhahlo. Ukuphila kwayo kwenkonzo ngokuvamile kusekelwe esimweni sangempela, ngaphandle kwezidingo ezikhethekile.
Umehluko phakathi kwezinto ezingavuthiwe kanye nobuchwepheshe bokucubungula
1. Izinto zokusetshenziswa ezihlukene
Ikhebuli ye-PV:
I-Conductor: i-conductor yocingo lwethusi olufakwe ethini.
I-insulation: ukufakwa kwe-polyolefin okuxhumene ngokuphambana.
Ijakhethi: ukufakwa kwe-polyolefin okuxhumene ngokuphambana.
Ikhebuli evamile:
Umqhubi: umqhubi wethusi.
Ukushisa: I-PVC noma i-polyethylene insulation.
Isigqoko: I-PVC sheath.
2. Ubuchwepheshe bokucubungula obuhlukene
Intambo ye-Photovoltaic: isikhumba sangaphandle siye saxhunyaniswa futhi safakwa imisebe.
Izintambo ezijwayelekile: ngokuvamile azingeni emisebeni exhumanisa, futhi amakhebuli kagesi ochungechunge lwe-YJV YJY azoxhunywa ngokuphambanayo.
3. Izitifiketi ezahlukene
Izintambo ze-PV ngokuvamile zidinga isitifiketi se-TUV, kuyilapho amakhebuli avamile ngokuvamile adinga isitifiketi se-CCC noma ilayisense yokukhiqiza kuphela.
