Abathengi abaninzi bahlala benemibuzo enje: Kutheni kufakelo lweenkqubo ze-pv, uqhagamshelo oluhambelanayo lweemodyuli zepv kufuneka lusebenzise iintambo ze-pv DC ezizinikeleyo endaweni yeentambo eziqhelekileyo?
Ukuphendula le ngxaki, masiqale sijonge umahluko phakathi kweentambo ze-pv DC kunye neentambo eziqhelekileyo:
1. Cable core: Iintambo eziqhelekileyo zisebenzisa iingcingo zobhedu ezisulungekileyo, ezityheli ngenkangeleko kwaye zinokufikelela kuphela iimfuno ezisisiseko zokuqhuba umbane.Intambo ye-pv DC isebenzisa intambo yobhedu enkonkxiweyo, kwaye inkqubo inzima ngakumbi kunocingo lobhedu olungenanto. Imbonakalo yesilivere.Ucingo lobhedu olutotiweyo luthambile kwaye lunonxibelelwano oluhle lombane.Xa kuthelekiswa nocingo olungenanto lobhedu, lunokuthintela iqokobhe lerabha ukuba linamathele, kwaye ukuxhathisa kwayo kwe-corrosion kunye nokumelana ne-oxidation kunamandla, okunokwandisa kakhulu ubomi benkonzo yeentambo zangoku ezibuthathaka.
2. Izinto zeqokobhe ezigqumayo:Iintambo eziqhelekileyo zisebenzisa i-XLPE insulation sheath.PV DC iintambo zigqunyiwe kwaye zigqunywe nge-irradiated cross-linked polyolefin.Isalathisi esingundoqo “i-irradiation” idla ngokuba emva kokukhanyiswa yi-radiation accelerator, ubume bemolekyuli yentambo. imathiriyeli iya kutshintshwa ukuze kufunyanwe ukusebenza ngamandla.Umzekelo:
3. Kwiqondo lokushisa eliphakamileyo kunye nemozulu ebandayo, uxinzelelo kunye nokugoba ukuxhathisa kuyaqina, kwaye kunomlinganiselo othile we-flame retardant effect, okungekho lula ukuvelisa amadangatye avulekileyo, njl. Ngaphezu koko, intambo ekhethekileyo ye-pv iya kuba ne- umaleko owongezelelweyo wokukhusela iqokobhe le-insulating kuneentambo eziqhelekileyo.
Ngamafutshane, intambo ye-pv DC inobomi obomeleleyo kunye nokuqina kuneentambo eziqhelekileyo, kwaye iyintambo yokuqhagamshela ifaneleke ngakumbi kwiinkqubo zokuvelisa amandla e-pv.Ke ngoko, ngokuqwalasela ukhuseleko kunye nokuzinza kwenkqubo ye-pv, kufuneka ukhethe ingcali.Intambo yePV DC.
I-TOCHN iyakhululaI-3kw kunye ne-5kw Power frequency inverters ngo-Agasti 1st, ngokubonakala okuphezulu, ukusebenza kweendleko eziphezulu, kunye ne-WIFI.Yenzelwe ukukuvumela ukuba uthenge iimveliso eziluncedo nezihle, ukonga iindleko kunye nexesha.
