Idivayisi yokuvikela ukukhuphuka kwelanga exhumayo yokuvikela uhlelo lwelanga noma i-inverter yephaneli yelanga
Ama-Surge Protective Devices (ama-SPD) abalulekile ekuvikeleni ama-solar photovoltaic (PV) inverters ekukhuphukeni kukagesi kanye nasezinhlansini, ikakhulukazi lawo abangelwa umbani. Ezindaweni ezinomsebenzi omkhulu wombani, izinhlelo ze-PV ezingavikelekile zingabhekana nomonakalo ophindaphindayo nomkhulu, okuholela ezindleleni ezinkulu zokulungisa, isikhathi eside sokungasebenzi, kanye nokulahlekelwa yimali engenayo. Ama-SPD afakwe kahle abalulekile ekunciphiseni umthelela wokushaywa umbani kanye nokuvikela izingxenye ezibucayi zezinhlelo ze-PV, kufaka phakathi ama-AC/DC inverters, amadivayisi okuqapha, kanye nama-PV arrays. Ngokutshala imali ekuvikelweni kokuqhuma okusebenzayo, ungaqinisekisa ukuthi uhlelo lwakho lwamandla elanga luhlala isikhathi eside futhi luthembekile.
Ungayikhetha kanjani idivayisi yokuvikela ukukhuphuka efanele yesicelo sakho esithile?
Ukukhetha idivayisi yokuvikela ukukhuphuka (i-SPD) efanele yohlelo lwakho lokusebenza kubalulekile. Qala ngokuhlonza uhlobo lwe-SPD oludingayo. Amadivayisi e-T1 asebenza kahle ezindaweni ezinobungozi obukhulu, njengezindawo ezivame ukushaywa umbani oqondile. Lokhu kuvamile ezakhiweni zezimboni noma ezinhlelweni ze-photovoltaic. Amadivayisi e-T2 asetshenziswa ngaphakathi endlini ukusingatha ukukhuphuka okungaqondile, kuyilapho amadivayisi e-T3 enikeza isivikelo esengeziwe kuma-electronics abucayi.
Hlola isilinganiso se-voltage ukuqinisekisa ukuthi ihambisana nesistimu yakho. Kumasistimu e-DC afana nokusethwa kwe-photovoltaic, ukukhetha idivayisi ene-voltage efanele kubalulekile. Uzofuna futhi ukuqinisekisa ukuthi umthamo wokukhipha ungabhekana namazinga okunyuka okulindelekile. Ezindaweni ezinobungozi obukhulu, umthamo ophezulu ubalulekile. Futhi ungakhohlwa ngesikhathi sokuphendula—ukusabela okusheshayo kubalulekile ekuvikeleni imishini ebucayi ekukhuphukeni kwamandla kagesi.
Cabanga ngendawo lapho i-SPD izofakwa khona. Uma ivezwe ezimweni ezinzima, khetha imiklamo engangenisi isimo sezulu noma evimbela ilangabi. Ngezinhlelo zokusebenza ezibalulekile, ama-SPD anokuqapha okude ahlinzeka ngezibuyekezo zokusebenza zesikhathi sangempela, ezisiza ngokulungiswa kanye nokufakwa esikhundleni. Okokugcina, qiniseka ukuthi i-SPD ihlangabezana nezindinganiso zemboni njenge-IEC 61643 futhi inezitifiketi ezifana ne-ISO noma i-CE.
Ama-SPD efektri yethu ahlangabezana nazo zonke izici ezibalulekile ezidingekayo ukuze kuvikelwe ngokwethembeka. Ngokukhetha amadivayisi ethu okuvikela ukukhuphuka, uzoqinisekisa ukuvikelwa okuhle kakhulu kanye nokuthembeka kwesikhathi eside kwemishini yakho.
Amakhono okuqapha akude angathuthukisa kanjani ukulungiswa kokuvikelwa kokukhuphuka?
Lokhu kuvumela izinkinga ezingaba khona ukuthi zitholakale kusenesikhathi, okuvumela ukulungiswa okusebenzayo ngaphambi kokuba kwenzeke ukwehluleka. Ngokubona izinkinga kusenesikhathi, amabhizinisi angahlela ukuhlolwa noma ukushintshwa ngesikhathi esifanele, okunciphisa ingozi yokungasebenzi okubizayo noma ukulimala kwemishini. Izexwayiso ezisheshayo zinciphisa nokuphazamiseka kwesistimu, ikakhulukazi engqalasizinda ebalulekile njengezinhlelo ze-photovoltaic noma izikhungo zezimboni, lapho ukuphazamiseka kukagesi kungaholela ekulahlekelweni okukhulu kwezezimali.
Ngaphezu kwalokho, ukuqapha kude kunciphisa izindleko zabasebenzi nezokulungisa ngokuqeda ukuhlolwa okungadingekile endaweni, kuyilapho kuqinisekiswa ukuthi amadivayisi okuvikela ukukhuphuka asebenza kahle. Ekufakweni okukhulu, ukulawulwa okuhlanganisiwe kwamadivayisi amaningi ezindaweni ezahlukene kwenza inqubo ibe lula, kuqinisekiswe ukuthembeka kanye nezimpendulo ezisheshayo ezinkingeni.
