Ukubaluleka komvikeli ohlinzayo ekukhiqizeni amandla e-photovoltaic

Njenganoma iyiphi idivayisi ye-elekthronikhi, ama-solar array angakwazi ukukhiqiza amandla kagesi angalimaza izingxenye futhi akhubaze idivayisi.idivayisi yokuvikela ukukhuphukaukusiza ukugcina isistimu isebenza.

Cabanga ngekhompyutha yasekhaya noma yasehhovisi.Ngokungeziwe kumadeskithophu noma amakhompyutha aphathekayo, kungase kube namamonitha angaphandle, izipikha noma ngisho namaphrinta.Izingxenye eziningi kakhulu azikwazanga ukuxhunywa odongeni, ngakho-ke abantu abaningi bathenge ibhodi lokushintsha.Nokho, iphaneli akuyona nje indlela elula yokunamathisela inqwaba yezinto esokhethini.Kuyasiza ngempela ukuvikela lawa ma-electronics emiphumeleni eyingozi yokuhlinzwa.

I-surge, eyaziwa nangokuthi i-voltage yesikhashana, ngokuvamile ibhekisela ekwenyukeni kwesikhashana kwamandla kagesi okuphakeme kakhulu kunokuvamile.Isibonelo, i-voltage ejwayelekile yekhaya noma ihhovisi ingu-120V.I-voltage ingacatshangwa njengomfutho kagesi.Ngakho-ke, njengoba nje umfutho wamanzi omningi ungabangela ukuthi ipayipi lengadi liqhume, i-voltage ephezulu kakhulu ingalimaza i-electronics.Lokhu kunyuka kungase kuvele emithonjeni yemvelo, efana nombani, kanye nangaphakathi noma ezintweni eziseceleni zegridi yamandla.

Idivayisi yokuvikela i-surgery isiza ukuvimbela ukulimala kwezinto zikagesi ngokudlulisela amandla ayinsalela isuka kolayini bamandla "Ashisayo" iye ezintanjeni eziphansi.Ezivikelini ezivamile zokuhlinzwa, lokhu kufezwa nge-metal oxide varistors (MOV) , ​​okungama-oxide ensimbi axhunywe kumandla nezintambo zaphansi ngama-semiconductors amabili.

Amandla elanga adinga i-Surge Protector

Amaphaneli elanga nawo angamadivayisi kagesi, ngakho-ke angaphansi kwezingozi ezifanayo zokulimala kokuhlinzwa.Amaphaneli elanga asengozini yokushaywa umbani ngenxa yendawo yawo enkulu kanye nokubekwa kwawo ezindaweni ezisobala, njengasophahleni noma ezindaweni ezivulekile phansi.

Osonkontileka abasebenzisa amandla elanga abahlale besazi noma bakha endaweni ejwayele ukushaya umbani.Hlanganisa idatha evela ku-US Lightning Detection Network ibe ithuluzi lamahhala elivumela osonkontileka belanga ukuthi bahlole izingozi zombani zamaphrojekthi abo.

Umbani ucishe ube ngu-50,000 ° F (uphakeme ngokuphindwe kahlanu kuneLanga), ngakho-ke akumangazi ukuthi ungaba yingozi emishinini yelanga.Uma ushaya iphaneli yelanga ngokuqondile, umbani ungase ushise izimbobo kudivayisi noma ubangele ukuqhuma, futhi lonke uhlelo luzobhujiswa.

Kodwa-ke, imiphumela yokukhanyisa nokunye okungaphezulu kwe-overvoltage ayibalulekile ngaso sonke isikhathi.Imiphumela yesibili yalezi zenzakalo ngeke ithinte kuphela izingxenye eziyinhloko ezifana namamojula nama-inverters, kodwa futhi nezinhlelo zokuqapha, izilawuli ze-spotter kanye neziteshi zesimo sezulu, kusho uSirava.

Ukuvikelwa kombani

Imiphumela yesibili ivamise ukuba yizingozi ezibonwa kancane.Ukulahleka kwemojula ye-PV kusho ukulahleka kwentambo, kuyilapho ukulahlekelwa kwe-inverter emaphakathi kuzosho ukulahlekelwa amandla ezingxenyeni eziningi zesitshalo.

Ukufakwa kwesivikeli sokuhlinza

Ngenxa yokuthi yonke imishini kagesi ivele ithinteke ngenxa yokuhlinzwa, i-SPD ingasetshenziselwa zonke izingxenye ze-solar array.Izinguqulo zezimboni zalezi zixhobo futhi zisebenzisa inhlanganisela ye-metal oxide varistors (MOV) nezinye izisetshenziswa ezingalindelekile ukuze zidlulisele ukugcwala ngokweqile komhlabathi.Ngenxa yalokho, i-SPD ivamise ukufakwa ngemva kokuba uhlelo lokubeka phansi oluvikelekile selusendaweni.

Kucatshangelwa umdwebo kagesi womugqa owodwa we-SPD ogelezayo osuka kusevisi yensizakalo ukuya kumpahla yamalungu afanayo, nempahla yokulungisa eqinile emnyango wokuqala, ukugwema ama-surge adlulayo amakhulu kanye namadivayisi amancane ukuthi afinyelele ekugcineni kwedivayisi emigwaqweni ebalulekile.

Amanethiwekhi e-SPD kufanele afakwe ekusatshalalisweni kwe-AC ne-DC kulo lonke uhlelo lwelanga ukuze kugcinwe amasekhethi abalulekile.Idivayisi ye-SPD izokhwezwa kokokufaka kwe-DC kanye nokuphumayo kwe-AC kwesiguquli sesistimu, futhi imigqa ye-DC ephozithivu nenegethivu izomiswa lapho isekelwe phansi.Ukugcinwa kwe-AC kuzosetshenziswa entanjeni ngayinye yamandla aphansi.Amasekhethi okuhlanganisa nawo azogcinwa, futhi wonke amasekhethi okulawula ngisho namasistimu okuqapha nawokugada azogcinwa ukuze kugwenywe ukuphazamiseka nokulahleka kwedatha.

Mayelana nohlelo lokuhlela ibhizinisi kanye nezinsiza, kunconywa umthetho we-10m.Kumadivayisi anobude bekhebula le-DC elingaphansi kuka-10m (33ft), idivayisi yokuvikela ukukhanya kwelanga le-DC kufanele ibekwe endaweni elula, njengendawo ye-inverter, ibhokisi lebhasi noma eduze kwemojuli yelanga.Okwamadivaysi anekhebula le-DC ubude elidlula i-10m,idivayisi yokuvikela ukukhuphuka kwelangaizofakwa ekugcineni kwe-inverter ye-inverter kanye nokuphela kwemojula yekhebula.

Amasistimu elanga okuhlala aneziguquli ezincane anezintambo ze-DC ezimfishane kakhulu, kodwa izintambo ze-AC ezinde.I-SPD efakwe ku-manifold ingavikela indlu emiphumeleni yokwanda kochungechunge.Ngokungeziwe kulokho kunyuka kwamandla kamasipala nezinye izisetshenziswa zangaphakathi, abavikeli bokuhlinzwa ebhodini lomama baphinde bavikele indlu ekuhlinzweni okuhlukahlukene.

Kumasistimu anoma yimuphi usayizi, i-SPD izosetshenziswa ochwepheshe bezogesi abanelayisensi ngokweseluleko somkhiqizi futhi ngokuhambisana nokufakwa nokufakwa okujwayelekile kukagesi ukuze kukhuliswe ukuphepha nokusebenza kahle.

Ezinye izinqubo zingamukelwa, njengokwengeza izinduku zombani ukuze uqhubeke nokugcina amaphaneli elanga ekukhanyeni.

Ngisho nohlelo olunamandla kakhulu lokulungisa ama-surge lunemikhawulo yalo.Isibonelo, i-SPD ayikwazi ukugwema ukulimala ngokomzimba okubangelwa umbani oqondile.

Lena into engcono kakhulu isayensi yesimanje engayenza:idivayisi yokuvikela ukukhuphuka
