Imililo yeNkqubo yaMandla eSola kunye noTshitshi lwe-Isolator yophahla oluqhushumbayo

Kubekho izehlo zomlilo ezininzi eNew South Wales kwiveki ephelileyo okanye ezibandakanya iinkqubo zamandla elanga â kwaye ubuncinci zimbini kucingelwa ukuba zibangelwe zizitshixo zokwahlulahlula eluphahleni.
Izolo, i-Fire and Rescue New South Wales ibike ukuba uye waya kwisiganeko kwikhaya lase-Woongarrah kuNxweme oluphakathi emva kokuba umnxeba we-triple-zero ubike umsi ophuma eluphahleni lwendlu.
âAbacimi-mlilo abasuka kwizikhululo zomlilo zaseHamlyn Terrace naseDoyalson bafike kwindawo yexhwayelo emva kwexesha elifutshane kwaye bakwazi ukuwucima ngokukhawuleza umlilo kwaye baqinisekisa ukuba awunwenwanga ngakumbi,â utshilo uMlilo noHlangulo. âIYunithi yoPhando loMlilo yeFRNSWâs ngoku isebenzela ukufumanisa unobangela womlilo, ekukholelwa ukuba uqalile kutshiso lodwa.â
Ngomhla wama-30 kuDisemba, abacimi-mlilo kunye namapolisa babizelwa kwidilesi ekwidolophu yaseNewcastle eBar Beach emva kweengxelo zokuba iipaneli zesola eziphezu kophahla zaziqhuma. Kwakhona, umlilo wacinywa phambi kokuba kwenzeke nawuphi na umonakalo omkhulu kwisakhiwo. Unobangela onokubakho awukhankanywanga.
Umlilo noHlangulo i-NSW ithe kulo nyaka uphelileyo imililo enxulumene nephaneli yelanga yonyuke ngokuphindwe kahlanu kule minyaka mihlanu idlulileyo, kodwa ayizange ibonelele ngamanani. Ngaphezulu kwe-600,000 yeenkqubo zamandla elanga zifakelwe eNew South Wales, kwaye naphi na apho izixhobo zombane ezixhaphakileyo zibandakanyeka kuya kubakho izehlo â kodwa oku akufunekanga kwamkelwe nje ukuba kukho indawo yokuphucula.
I-FRNSW ikhe yaphawula ngaphambili ukuba i-isolator switches ibalwe malunga nesiqingatha somlilo wenkqubo yamandla elanga kurhulumente. Ngelixa umlinganiselo wabahlukanisi bophahla lwendlu engunobangela awukhankanywanga, kusenokwenzeka ukuba uninzi lwabo lunikwe irekhodi yezi zixhobo ziyingxaki.
Uphahla lwe-DC isolator iswitshi lutshintsho oluqhutywa ngesandla olufakwe ecaleni koluhlu lwephaneli yelanga eyenza ukuba i-DC yangoku phakathi koluhlu kunye ne-solar inverter ivalwe. Okumangalisayo kukuba, yayijongwe njengendlela eyongezelelweyo yokhuseleko kwaye iyimfuneko kuzo zonke iinkqubo zamandla elanga e-Australia. Kodwa kubonakala ngathi kuphela kwelizwe elisafuna ukusetyenziswa kwabo.
Uninzi lwabafakeli belanga bajongela phantsi ukufakela uphahla lwe-DC izitshixo zokwahlulahlula kwaye kukho iintshukumo zokususwa kweemfuno kwiMigangatho yase-Australia â kwaye ayinakuza kwakamsinyane. Kukwakho utyhalo lokususa izinto zokwahlula ezixhonywe eludongeni; endaweni yoko ifuna i-isolator efakwe ngaphakathi kwi-inverter yelanga.
Ezo zimpucuko ezimbalwa ezinokwenziwa â enye ngabanini bajonga iinkqubo zabo.
Izitshixo zokwahlulahlula zodwa ze-DC ezifakwe ngokufanelekileyo kwaye zikhuselwe ngokufanelekileyo ngeqhiya zikhuselekile ngokubanzi. Iqhiya yenye imfuneko esele ikhona kangangexesha elithile kwaye isitshixo soyedwa kwisehlo sayizolo khange sibonakale sinayo. Mhlawumbi ufakelo lwangaphambili kwimfuno, kodwa ukuseta ngokubanzi kujongeka njengento ebambekayo.
Ukhuseleko lomlilo sesinye isizathu esibalulekileyo sokukhetha i-installer efanelekileyo yelanga. Kodwa nokuba leliphi icandelo kunye nomgangatho wofakelo kunye neemeko ezirhabaxa kuphahla lwe-DC izitshixo zokwahlukanisa kunye nezinye iinxalenye zesixokelelwano samandla elanga kufuneka zinyamezele kwiminyaka emininzi, kubalulekile ukuba kubekho uhlolo kunye novavanyo lwenkqubo lwenziwa rhoqo emva kweminyaka embalwa.
UMichael ubambe isiphene samandla elanga emva kokuthenga izinto zokudibanisa inkqubo encinci ye-PV engaphandle kwegrid ngo-2008. Ebesenza ingxelo ngeendaba zamandla elanga zase-Australia kunye nezamazwe ngamazwe ukusukela ngoko.
Ngapha koko, yiyo loo nto banyanzelise imfuno yobudenge yokubeka izahluli ze-DC phezu kwezindlu, ukuze zibangele iingxaki, akunjalo?
Kufana nokufuna iinkqubo zamanzi ashushu ukuba zizale kwaye zisasaze i-legionella, ngokuvala amanzi ashushu kwizifudumezi zamanzi.
Andizange ndiqonde ukuba ingqiqo ye-DC isolator kufuneka ibe kwiiphaneli zophahla. Umsebenzisi oqhelekileyo akayi kuvuka ileli ukuze ahlukanise iipaneli ngenxa yaso nasiphi na isizathu. Izixhobo zokwahlula zodwa kufuneka zibe kumgangatho osezantsi ekufikeleleni lula.
Ndineesistim ezi-3 zelanga. Eyokuqala ifakwe ngo-2011. Akukho isolator ye-DC kwiphaneli kodwa kukho i-DC isolator ecaleni kwe-inverter.
Inkqubo yesithathu ifakwe kwi-2018, ine-DC isolators kwiipaneli zephahla kunye nokuba kufuphi ne-inverter (isethi ephindwe kabini ye-DC isolators).
Isigqubuthelo sigcina ilanga kwi-DC isolator iswitshi esinceda ukuba siyeke ukuba shushu kakhulu kwaye sinqande ukuthotywa kwe-UV. Ikwagcina eyona mvula imbi kakhulu kuyo.
I-ADELS NL1 Series I-DC Isolator Switshi isetyenziswe kwi-1-20KW indawo yokuhlala okanye inkqubo ye-photovoltaic yorhwebo, ibekwe phakathi kweemodyuli ze-photovoltage kunye ne-inverters. Ixesha le-Arcing lingaphantsi kwe-8ms, egcina inkqubo yelanga ikhuselekile ngakumbi. Ukuqinisekisa uzinzo kunye nobomi benkonzo ende, iimveliso zethu zenziwe ngamacandelo anomgangatho ophezulu. Amandla ombane aphezulu ukuya kuthi ga kwi-1200VDC. Ibamba ukhokelo olukhuselekileyo phakathi kweemveliso ezifanayo.
