Kwiposti yethu yangaphambili, sinikeze abafundi isikhokelo esiluncedo kwiipaneli zelanga zasekhaya.Apha siya kuqhubeka nalo mxholo ngokukunika isikhokelo esahlukileyo kwiintambo zelanga.
Iintambo zelanga, njengoko igama libonisa, ziindlela zokuhambisa umbane.Ukuba umtsha kwiinkqubo zePV, kubalulekile ukufunda iziseko.
Funda ukuze ufunde ngakumbi ngolu hlobo lwentambo, kubandakanywa nendlela abasebenza ngayo, into abasetyenziselwa yona, kunye nendlela yokukhetha intambo efanelekileyo.
Intambo yelanga kwi-photovoltaic system
Logama nje kukho umbane, kufuneka kubekho iingcingo neentambo.Iinkqubo ze-Photovoltaic azikho ngaphandle.
Iingcingo kunye neentambo zidlala indima ebalulekileyo ekufumaneni ukusebenza kakuhle kwiinkqubo zombane.Kwimeko yeenkqubo ze-photovoltaic, imfuno yomgangatho ophezulu weentambo zelanga kunye neentambo ziba zibaluleke kakhulu.
Iinkqubo ze-Photovoltaic ziquka iipaneli zelanga enye okanye ngaphezulu ezidityaniswe ne-inverters kunye nezinye izixhobo.Isebenzisa amandla elanga ukwenza umbane.
Ukufumana ubuninzi belanga, inkqubo ye-photovoltaic okanye iphaneli yelanga kufuneka isebenze "ngokucacileyo" kunye nokulandelelana.Elinye lamacandelo abalulekileyo yintambo yelanga.
Bazintoni?
Iintambo zelanga zenzelwe ukuhambisa amandla elanga e-DC ngokusebenzisa iinkqubo ze-photovoltaic.Zisetyenziselwa njengeentambo ezidibeneyo kwiipaneli zelanga kunye ne-photovoltaic arrays kwigridi yelanga.
Banamandla omatshini aphezulu kwaye banokumelana neemeko zemozulu ezinzima.Kwiiprojekthi zelanga, iintambo zelanga zibekwe ngaphandle kwaye zibekwe kubushushu obuphezulu.
Ebudeni bobomi babo obude obumalunga nama-20 ukuya kuma-25 eminyaka, banokujamelana nemekobume enzima.Ngoko ke, kubalulekile ukuxhobisa inkqubo yakho yelanga kunye neengcingo eziphezulu zelanga kunye neentambo.
Iintambo zelanga zihlelwa ngokusekelwe kwinani leentambo kunye neenkcukacha zazo.Ukongezelela, ububanzi buxhomekeke kwinani leengcingo kunye neenkcukacha zabo.
Ngokuqhelekileyo, kukho iintlobo ezintathu zeentambo zelanga ezisetyenziswa kwiinkqubo ze-photovoltaic:
Dc intambo yelanga
Intambo engundoqo yeSolar DC
Intambo ye-solar ac
Iintlobo zentambo yelanga
Kwiiprojekthi zombane welanga, iintlobo ezahlukeneyo zeentambo ziyafuneka ukuze kwenziwe umsebenzi.Zombini iintambo ze-DC kunye ne-AC zinokusetyenziswa.
Iphaneli ye-photovoltaic kunye ne-inverter, kubandakanywa nebhokisi ye-junction, ixhunyiwe ngentambo ye-DC.Ngexesha elifanayo, i-inverter kunye ne-sub-station ixhunywe ngekhebula le-AC.
1. Intambo yelanga yeDc
Iintambo zelanga zeDc ziintambo zobhedu ezinondoqo ezine-insulation kunye nesheathed.Zisetyenziselwa ngaphakathi kweepaneli zelanga ze-photovoltaic kwaye zingaba neentambo zemodyuli okanye iintambo zeentambo.
Ukongeza, beza kunye nezixhumi ezifanelekileyo kwaye zakhiwe ngaphambili kwiphaneli.Ngoko ke, awuyi kukwazi ukuzitshintsha.
Kwezinye iimeko, uya kufuna intambo yeentambo zelanga ze-DC ukuyidibanisa kwezinye iiphaneli.
2. Intambo enkulu yelanga ye-DC
Intambo enkulu yeDC yintambo enkulu yokuqokelela amandla.Badibanisa ibhokisi ye-generator junction kwiintambo ezintle kunye nezibi ze-inverter ephakathi.
Ukongeza, banokuba yintambo eyodwa okanye ezimbini ezingundoqo.I-single core wire kunye ne-insulation kabini sisisombululo esisebenzayo sokubonelela ngokuthembeka okuphezulu.Ngexesha elifanayo, ukudibanisa phakathi kwe-inverter yelanga kunye nebhokisi ye-junction ye-generator, ukusetyenziswa kakuhle kwe-double-core DC cable.
Iingcali ngokubanzi zikhetha ukufakelwa kwangaphandle kweentambo eziphambili zelanga ze-DC.Ubukhulu buqhele ukuba yi-2mm, 4mm kunye ne-6mm.
Qaphela: Ukuze ugweme iingxaki ezifana nokujikeleza okufutshane kunye nokumisa phantsi, kucetyiswa ukuba iintambo ezine-polarity ezichaseneyo zihanjiswe ngokwahlukeneyo.
3. Intambo yeAc
Iintambo ze-Ac zidibanisa i-inverter yelanga kwizixhobo zokukhusela kunye negridi yamandla.Kwiinkqubo ezincinci ze-PV ezine-inverters zesigaba sesithathu, intambo ye-AC ye-five-core isetyenziselwa ukuxhuma kwigridi.
Ukuhanjiswa kweengcingo ngolu hlobo lulandelayo:
Iingcingo ezintathu eziphilayo,
Ucingo olunye olusezantsi kunye nolunye ucingo olungathathi hlangothi.
Ingcebiso: Ukuba isixokelelwano sakho sePV sinesigaba esinye soguqulo, sebenzisa intambo ye-AC enemigangatho emithathu.
Ukubaluleka kwentambo yelanga kwiiprojekthi zePV
Njengoko bekutshiwo ngaphambili, iintambo zelanga zihambisa amandla elanga e-DC ukusuka kwindawo enye yesixhobo se-photovoltaic ukuya kwenye.Ulawulo olululo lwekhebula lubalulekile xa kufikwa kukhuseleko kunye nobomi benkqubo nganye yePV.
Ukufakwa kweentambo kwiiprojekthi zelanga kuxhomekeke kwimitha ye-ultraviolet, amaqondo obushushu agqithisileyo kunye nomswakama womoya.Bangakwazi ukumelana neemfuno ezinzima zeenkqubo ze-photovoltaic - zombini ngaphakathi nangaphandle.
Ukongeza, ezi ntambo azinamandla nje kuphela, kodwa ziyakwazi ukumelana nemozulu.Banokumelana noxinzelelo loxinzelelo, ukugoba okanye ukolula, kunye noxinzelelo lweekhemikhali ngohlobo lwe:
Khetha intambo yelanga efanelekileyo kwinkqubo yakho yePV
Iintambo zelanga kufuneka zanele kwezona nkqubo zifunwayo kakhulu zePV.Khetha imodeli enokumelana okuphezulu nemiceli mngeni yomoya efana ne-UV, i-ozone, kunye nokufuma.
Akunjalo kuphela, kodwa intambo kufuneka ikwazi ukumelana namaqondo okushisa anzima (-40 ° C ukuya kwi-120 ° C).Kukho ukuguga, impembelelo, ukukrazula kunye noxinzelelo.
Inyathelo elinye ukuya phambili, uhlobo olufanelekileyo lwelanga
