Imililo Yesistimu Yamandla Elanga Kanye Nokushintsha Kokuhlukanisa Ophahleni Oluqhumile

Kube khona izehlakalo zomlilo ezimbalwa eNew South Wales evikini eledlule noma ngaphezulu ezibandakanya amasistimu kagesi welanga â futhi okungenani ezimbili kucatshangwa ukuthi zidalwe amaswishi ahlukanisayo ophahleni.
Izolo, iFire and Rescue New South Wales ibike ukuthi ihambele isigameko somuzi oseWoongarrah eCentral Coast ngemuva kokuthi umuntu oshaye ucingo oluphindwe kathathu ebike intuthu ephuma ophahleni lwendlu.
âIzicishamlilo ezivela eziteshini zokucima umlilo i-Hamlyn Terrace nase-Doyalson zifike endaweni yesigameko ngemuva kwesikhashana futhi zakwazi ukucisha umlilo ngokushesha zaphinde zaqinisekisa ukuthi awusabalali ngokuqhubekayo,â kusho i-Fire and Rescue. âI-FRNSWâs Fire Investigation and Research Unit okwamanje isebenzela ukuthola imbangela yomlilo, okukholakala ukuthi uqale kumshini wokuzihlukanisa.â
Ngomhla zingama-30 kuZibandlela, izicishamlilo namaphoyisa babizelwa ekhelini elisendaweni yaseNewcastle e-Bar Beach ngemuva kwemibiko yokuthi amaphaneli elanga ophahleni lwendlu ayeshunqa. Nalapha futhi, umlilo wacishwa ngaphambi kokuba kwenzeke noma yimuphi umonakalo omkhulu wesakhiwo. Imbangela engaba khona ayishiwongo.
I-Fire and Rescue i-NSW ithe ngonyaka odlule imililo ehlobene namaphaneli elanga inyuke ngokuphindwe kahlanu eminyakeni emihlanu edlule, kodwa ayizange inikeze izinombolo. Ngaphezu kuka-600,000 amasistimu wamandla elanga afakiwe eNew South Wales, futhi nomaphi lapho izinto zikagesi ezisabalele ezihilelekile kuzoba nezigameko â kodwa lokhu akufanele nje kwamukelwe uma kukhona isikhala sokuthuthukiswa.
I-FRNSW phambilini ike yaphawula ukuthi ukushintsha kwe-isolator kubalele cishe ingxenye yomlilo wesistimu yamandla elanga esifundazweni. Nakuba ingxenye yezihlukanisi ezisophahleni kuyimbangela ayizange ikhulunywe, cishe iningi labo linikezwe irekhodi lale mishini eyinkinga.
I-rooftop DC isolator switch iyiswishi esebenza ngesandla efakwe eduze kwephaneli yelanga evumela ukuthi i-DC yamanje phakathi kwe-array kanye ne-solar inverter ivalwe. Okuxakayo ukuthi ibihloselwe njengendlela yokuphepha eyengeziwe futhi iyimfuneko yazo zonke izinhlelo zamandla elanga e-Australia. Kodwa kubonakala kuyizwe kuphela elisadinga ukusetshenziswa kwabo.
Izifaki eziningi ze-solar ziyakwenyanya ukufaka amaswishi e-isolator e-sophahleni ye-DC futhi kukhona ukunyakaza ukuze kususwe imfuneko kokuthi Amazinga ase-Australia â futhi lokho ngeke kuze maduzane. Kukhona futhi ukuphusha ukuze uqede izihlukanisi ezibekwe odongeni; esikhundleni salokho idinga i-isolator efakwe ngaphakathi kwe-inverter yelanga.
Lokho ukuthuthukiswa okumbalwa okungenziwa â okunye abanikazi abahlolwa amasistimu abo.
Amaswishi e-isolator ekhwalithi enhle ye-DC afakwe kahle futhi avikelwe ngempumelelo ngendwangu ngokuvamile aphephile. I-shroud enye imfuneko ekhona isikhathi eside futhi isihlukanisi esishintshayo esehlakalweni sayizolo asizange sibe naso. Mhlawumbe ukufakwa kubikezele imfuneko, kodwa ukusetha ngokuvamile kwakubukeka kuyinqaba.
Ukuphepha komlilo kungesinye isizathu esibalulekile sokukhetha isifaki esihle selanga. Kodwa ngokunganaki ingxenye nekhwalithi yokufaka futhi uma kubhekwa izimo ezinzima zokushintsha kwesihlukanisi sophahla lwe-DC nezinye izingxenye zesistimu yamandla elanga kufanele kubekezelele iminyaka eminingi, kubalulekile ukuba nokuhlolwa nokuhlolwa kwesistimu kwenziwe njalo ngemva kweminyaka embalwa.
U-Michael ubambe isiphazamisi samandla elanga ngemva kokuthenga izingxenye zokuhlanganisa isistimu encane ye-PV ye-off-grid ngo-2008. Ubelokhu ebika ngezindaba zamandla elanga zase-Australia nezamazwe ngamazwe kusukela ngaleso sikhathi.
Phela, yingakho babeka imfuneko yobuwula yokubeka izihlukanisi ze-DC ophahleni lwezindlu, ukuze zibangele izinkinga, akunjalo?
Kufana nokudinga izinhlelo zamanzi ashisayo ukuzalanisa nokusabalalisa i-legionella, ngokuvimbela amanzi ashisayo kwizishisi zamanzi.
Angikaze ngiqonde ukuthi i-logic ye-isolator ye-DC kufanele ibe kumaphaneli ophahleni. Umsebenzisi ojwayelekile ngeke avuke isitebhisi ukuze ahlukanise amaphaneli nganoma yisiphi isizathu. Ama-isolator kufanele abe sezingeni eliphansi endaweni okufinyeleleka kalula kuyo.
Nginamasistimu elanga angu-3. Eyokuqala efakwe ngo-2011. Ayikho i-isolator ye-DC kuphaneli kodwa kune-isolator ye-DC eduze kwe-inverter.
Uhlelo lwesithathu lwafakwa ngo-2018, lunama-isolators e-DC kumaphaneli ophahleni kanye nokuba eduze kwe-inverter (isethi ephindwe kabili ye-DC isolator).
I-shroud igcina ilanga lingangeni kuswishi ye-isolator ye-DC esiza ukuyiyeka ishise kakhulu futhi ivimbele ukuwohloka kwe-UV. Iphinde ivimbele imvula embi kakhulu.
I-ADELS NL1 Series DC Isolator Switches isetshenziswa ku-1-20KW isistimu ye-photovoltaic yezohwebo, ebekwe phakathi kwamamojula we-photovoltage nama-inverters. Isikhathi se-arcing singaphansi kuka-8ms, okugcina isimiso sonozungezilanga siphephe kakhudlwana. Ukuqinisekisa ukuzinza nempilo ende yesevisi, imikhiqizo yethu yenziwa izingxenye ezinekhwalithi ephezulu. I-voltage enkulu ifinyelela ku-1200VDC. Iphethe ukuhola okuphephile phakathi kwemikhiqizo efanayo.
