Zeziphi izinto eziluncedo zoTshintsho loKhuseleko loMlilo wePV?

   Iswitshi yokhuseleko lomlilo wePVsisisombululo sokuvalwa kwepaneli yelanga esihambelanayo nazo zonke ii-inverters zeentambo eziqhelekileyo.Okwangoku, ii-photovoltaics ezisasazwa ngophahla zisetyenziswe ngokubanzi e-China, e-United States, e-Australia, eYurophu naseJapan.Indlela yokuqinisekisa ukhuseleko lomntu, indlela yokuthintela umngcipheko womlilo wezixhobo ze-photovoltaic, kunye nendlela yokuqinisekisa ukuba abangengabo abachwephesha bachonga kwaye banqumle imingcipheko ngexesha lokuqala baye baba yinkxalabo eqhelekileyo kuwo onke amazwe.I-Slocable iphambili kubuchwephesha obuphuhliswe ngokukodwa kwimarike yamandla ahlaziyekayo, ngakumbi amandla elanga, ehlangabezana neemfuno zokutshintsha okukhuselekileyo nokusebenzayo kwe-DC, ehlangabezana neyona migangatho iphezulu yobugcisa neyorhwebo.

Kwiinkqubo ze-photovoltaic, kukho iingozi ezimbini zokhuseleko: "ingozi ye-DC ephezulu" kunye "nomngcipheko wokuhlangula".Kwinkqubo yochungechunge lwendabuko, i-voltage iyonke yomgca wechungechunge inokufikelela kwi-600V ~ 1000V.Ngenxa yoqhagamshelwano olukhululekileyo lwezihlanganisi ze-photovoltaic, uqhagamshelwano olubi, iingcingo ezimanzi, kunye nokugqabhuka kwe-insulation, kulula ukubangela i-DC arcing, enokubangela umlilo.Ukongezelela, xa ingozi yomlilo ivela ngenxa yokutsala i-arc okanye izizathu zangaphandle, kwimeko yecala le-DC, i-current iveliswa nje ngokuba kukho icandelo lokukhanya.Amandla ombane aphezulu ahlala ekhona.Ukulwa nomlilo kuyingozi kakhulu kwaye abacimi-mlilo abakwazi ukuhlangula indawo kwaye banokulawula kuphela umlilo kude.

I-Slocable iye yasungula i-DC isolator switches kunye ne-PV firefighter switching yokhuseleko ngokwemfuno yemarike.Kwiinkqubo ezininzi zePV,Iiswitshi zokuqhawula i-DCzihlanganiswe kwi-DC / AC inverter yamandla, kwaye injongo yazo ephambili kukunqumla i-inverter DC ngexesha lokugcinwa, kodwa ayikwazi ukwenza nantoni na malunga ne-DC (600 ~ 1500V) ukusuka eluphahleni ukuya kwicandelo le-inverter.Iintambo phakathi kweemodyuli zelanga ze-DC kunye ne-DC / AC inverters zamandla zisaxhomekeke kwi-1000 VDC ngelixa zisebenza ngaphakathi kwesakhiwo emva kokuba i-DC yokuqhawula intambo icinyiwe.Kwimeko yomlilo, abacimi-mlilo banokubonakala kwiingozi eziyingozi kakhulu.

I-Slocable firefighter switch switch inika isisombululo apho abacimi bomlilo baqhawula isiphaluka samandla e-AC ngaphambi kokucima umlilo ukuze baqalise ukulwa nomlilo ngaphandle komngcipheko wokutshatyalaliswa kwe-electrocution.Umtshini wokhuseleko lomlilo ufumanisa ukungaphumeleli kwegridi kwaye ucima ngokuzenzekelayo ukutshintshwa kwe-isolator emva kwemizuzwana ye-5, ukudala indawo ekhuselekileyo kubacimi bomlilo.(Amandla e-AC avaliwe = umbane we-DC ucinywe ngokuzenzekelayo; ukusetha kwakhona ngokuzenzekelayo xa amandla e-AC ebuyiselwa = ukubuyiswa kombane we-DC) Inkqubo yokutshintsha ukhuseleko lomlilo we-PV inokukhawuleza, ngokupheleleyo kwaye ikude ikhutshwe kwi-PV yokufakela kunye nesenzo esilula kwi-interface yepaneli yokulawula, kwaye inokusetyenziswa ukude kwinethiwekhi yefowuni ephathwayo.Ngokuqhawula ukufakwa kwe-PV, akukho mandla e-DC aqhutywayo kwi-PV array, kunye ne-high-voltage DC amandla avela kwiimodyuli ze-PV aya kuba yedwa ngokupheleleyo, ebonelela ngeemeko ezikhuselekileyo kubacimi bomlilo ukucima umlilo kwaye bangene kwisakhiwo.

Ngokusebenza okugqwesileyo, ixesha lokuhambisa ngokukhawuleza kunye neqela leengcali emva kokuthengisa ngokukhawuleza ukuphendula kwiimfuno zabathengi, iiswitshi zokhuseleko lomlilo we-Slocable zithengisa kakuhle kwimarike yaseYurophu kwaye ziqhubeka zamkelwa kakuhle ngabathengi.

Nangona sinemizila yokuvelisa ngokuzenzekelayo yokuvelisa ubuninzi kunye noluhlu olupheleleyo lwezisombululo eziqhelekileyo, abathengi bethu banezidingo ezikhethekileyo ezilungiselelwe, kwaye siya kusebenza naba bathengi ukuphuhlisa isisombululo esona sihle kwiimfuno zabo.

Iimfuno ezingqale ngqo kuMthengi zisenokwahluka ngokwendibano ethile yemathiriyeli esele ikho, kodwa inokubandakanya uphuhliso lwamaqhina akhethekileyo okanye iindlela.I-Slocable iyakwazi ukubonelela abathengi ngenkonzo ebanzi kakhulu, sineqela leenjineli, abaqulunqi kunye namagcisa.

I-NEC2017 idinga ukufakelwa kwe-PV kuzo zonke izakhiwo ukuze zikwazi ukufikelela ngokukhawuleza ukuvalwa kwemodyuli kwiimeko ezingxamisekileyo.I-NEC 2017 690.12 nayo ineemfuno ezingqongqo zokutshintsha ukucima ngokukhawuleza.Umgama ongaphakathi kwe-305mm ukusuka kwi-photovoltaic array ngumda.Ngaphakathi kwe-30 emva kokuba isixhobo sokucima ngokukhawuleza siqaliswe, i-voltage ye-array ngaphandle komda ihla ngaphantsi kwe-30V, kwaye i-voltage ngaphakathi komda iyancipha ngaphantsi kwe-80V, oko kukuthi, ukuvala kwinqanaba lepaneli kuyadingeka.Lo mqathango uqale ukusebenza nge-1 kaJanuwari 2019.

Emva kokufaka i-PV yokukhusela ukhuseleko lomlilo, imodyuli nganye ye-photovoltaic inokwahlulwa ukuphepha ingozi yombane ophezulu.Kwimeko yomlilo, i-voltage ephumayo yemodyuli inokunqunyulwa ngexesha lokuqala ukuqinisekisa ukhuseleko lwabacimi bomlilo.

Ungayikhetha njani iModeli yokuTshintsha yoMlilo woMlilo oLungileyo:

1. Qinisekisa i-voltage kunye nekhoyo ngoku efunekayo yinkqubo ye-photovoltaic
2. Iimfuno ze-Interface: I-Knockouts |Amadlala ekhebhile |MC4 isidibanisi ngokuzithandela
3. I-1 imitha yentambo ye-AC efunekayo okanye hayi
4. 1 ~ 5 imitya ekhoyo
