Idivaysi yokuvikelwa kwe-jcspv Photovoltaic Surge: Ukuvikela Ukutshalwa Kwezimali Kwakho Ngobunzima Bama-Lightning
Esikhathini esingokwendawo esivuselelekayo, ama-Photovoltaic (PV) amasistimu aqhamuke njengetshe lesisekelo sokuzinza kwamandla okuzinzile. Kodwa-ke, lezi zinhlelo azingeneki ezinsongo zangaphandle, ikakhulukazi lawo abuzwe ngombani. Umbani, ngenkathi uvame ukubonwa njengesibonisi semvelo esimangazayo, kungalimaza ukufakwa okubonakalayo ekufakweni kwe-PV, kubangele ukulimala okukhulu kwezakhi ezibucayi nokuphazamisa ukuthembeka kohlelo lonke. Ukubhekana nalokhu kukhathazeka,Idivaysi yokuvikela i-jcsppt photovoltaic SurgeIklanywe ngokucophelela ukuvikela amasistimu e-PV kwimiphumela elimazayo ye-Lightning Surge Voltages. Le ndatshana idlulela kwidivaysi yokuvikelwa kwe-JCSPV, igqamisa izici zayo ezibalulekile, izindlela, nendima ebaluleke kakhulu ekuqinisekiseni ukuphepha nokuphila isikhathi eside kwezinhlelo ze-PV.
Ukuqonda Usongo: I-Indernic Lightning Strikes kanye nomthelela wazo
I-Inderning Lightning Strikes, ngokungafani nokushaya okuqondile, kuvame ukunakekelwa ngaphansi kwamandla abo okubhubhisa. Ukubonwa kwe-anecdotal ngomsebenzi wombani kuvame ukwehluleka ukukhombisa ngokunembile izinga lokukhanya okubangelwa umbani ngaphakathi kwe-PV. Lezi ziteleka ezingaqondile zingakhipha ama-currents ezi-transteent kanye nama-voltages ngaphakathi kwezinsimbi zohlelo lwe-PV zohlelo lwe-PV, zihamba ngezintambo futhi zingabangela ukufakwa kanye nokuhluleka kwe-dielectric ngaphakathi kwezakhi ezibucayi.
Amaphaneli we-PV, ama-inverterers, ama-control kanye nemishini yezokuxhumana, kanye namadivayisi ngaphakathi kokufakwa kokwakha, asengozini ikakhulukazi. Ibhokisi le-combiner, i-inverter, kanye ne-mpt (amandla aphezulu we-Point Tracker) amafomu aphawulekayo wokwehluleka, ngoba avame ukuvezwa amazinga aphezulu e-Currents kanye nama-voltages ashubile. Ukulungiswa noma ukushintshwa kwalezi zinto ezilimele kungabiza kakhulu futhi kuthinte kakhulu ukuthembeka kohlelo.
Isidingo seUkuvikelwa Kokuhlinzwa: Kungani izindaba ze-jcspv
Njengoba kunikezwe imiphumela emibi yombani kugawulwa ezinhlelweni ze-PV, ukusetshenziswa kwamadivayisi okuvikela aSurge kuba ukubalulekile. Idivaysi yokuvikelwa kwe-JCSPV Photovoltaic Surge i-Extered ngqo ukunciphisa ubungozi obuhambisana nama-voltages ahlinzwa. Ngokusebenzisa ubuchwepheshe bezwe-kwezobuciko, le divayisi iqinisekisa ukuthi ama-currients aphezulu awadluli ngezinto ezenziwa nge-elektroniki, ngaleyo ndlela avimbele ukulimala kwamandla kagesi aphezulu ohlelweni lwe-PV.
Kutholakala ngezilinganiso ezihlukene ze-voltage, kufaka phakathi i-500VDC, i-600VDC, i-800VDC, i-12000VDC, i-1200VDC yokuvikelwa kwensiza, i-JCSPV Surge Ukuvikelwa Kokumiswa Kwabaningi Lokucushwa Kwezistimu ye-PV. Izinhlelo zayo ezihlukanisiwe ze-DC Voltage ngezilinganiso ezifika ku-1500v DC zingaphatha imisinga yokujikeleza okufushane iphakeme njenge-1000a, ekhombisa ukuqina kwayo kanye nokwethembeka.
Izici ezithuthukile: Ukuqinisekisa ukuvikelwa okuphezulu
Enye yezinto zokusukuma ze-JCSPV Photovoltaic Surge Surder Support iyikhono layo lokuphatha ama-voltages we-PV aze afike ku-1500v DC. Ngokukhipha okungamanje kwamanje kwe-20Ka (8/20 μs) ngandlela thile kanye nokukhishwa okuphezulu kwamanje kwe-40ka (8/20 μs), le nsimbi inikeza ukuvikela okungekho emthethweni ekulweni kwezibani ezibangelwa ngumbani. Lokhu kunamandla okunamandla kuqinisekisa ukuthi ngisho nangesikhathi sokuduma okukhulu okunzima, uhlelo lwe-PV luhlala luvikeleke ekulimaleni okungenzeka.
Ngaphezu kwalokho, i-plug-in modul design yedivaysi ye-JCSPV Surge Vikela kusiza ukufakwa okulula nokulungiswa. Lo mklamo awusebenzi nje kuphela inqubo kodwa futhi uqinisekisa ukuthi idivaysi ingathathelwa indawo ngokushesha nangendlela efanele, inciphise isikhathi sokuphumula kanye nokuqinisekisa ukuqhubeka kokuqina kwamandla.
Uhlelo lwezinkomba zesimo esikahle luphinde luthuthukise ukusetshenziswa kwensiza. Isibani esiluhlaza sibonisa ukuthi idivaysi yokuvikela eSurge isebenza kahle, kuyilapho ukukhanya okubomvu kudinga ukushintshwa. Lesi sikhombisi esibonakalayo senza ukuqapha kanye nokugcina uhlelo lwe-PV liqonde futhi alunamthungo, ukuvumela abahlinzeki ukuthi bathathe isinyathelo ngokushesha lapho kunesidingo.
Ukuhambisana nokuvikelwa okuphakeme
Ngaphezu kwezici zayo ezithuthukile, i-JCSPV Photovoltaic Surge Ukuvikelwa Ukuvikelwa Kwedivaysi kuhambisana ne-IEC61643-31 kanye no-En 50539-11. Lokhu kuthobela kuqinisekisa ukuthi idivaysi ihlangabezana namabhentshi aqinile amazwe aphesheya wokuvikelwa kwamanye amazwe, ukuhlinzeka abanikazi bohlelo lwe-PV ngokuthula kwengqondo ukuthi ukutshalwa kwezimali kwawo kuvikelwe ezindinganisweni eziphakeme kakhulu.
Izinga lokuvikelwa kwe- ≤ 3.5kv ligcizelela amandla wedivayisi okumelana namandla e-voltages aphezulu, ngaleyo ndlela avikele uhlelo lwe-PV ekuhlulekeni okungenzeka kube yinhlekelele. Leli zinga lokuvikelwa libalulekile ekugcineni ukusebenza kwesikhathi eside kanye nokwethenjwa kohlelo lwe-PV, ukunciphisa ubungozi bomonakalo kanye nokwelula isikhathi sokuphila kwalo.
Izicelo eziguquguqukayo: kusuka ekuhlalweni kwezimboni
Ukuguquguquka okuhlukahlukene kwedivaysi yokuvikela i-JCSPV Photovoltaic Surge yenza kube yisixazululo esifanelekile sezicelo ezahlukahlukene. Noma ngabe uhlelo lokuhlala ophahleni lwePV noma ukufakwa kwezimboni ezinkulu zezimboni, le divayisi iqinisekisa ukuthi uhlelo lwe-PV luvikelekile ezingozini zombani.
Ezimweni zokuhlala, lapho izindleko zokulungisa noma ukufaka esikhundleni sezinto ezilimele kungabaluleka, idivaysi yokuvikelwa kwe-JCSPV ihlinzeka ngesisombululo esingesibi esibizayo sokuvikela imali. Idizayini yayo ecwecwe kanye nokufakwa okulula kwenza kube inketho ekhangayo yabanini bamakhaya abafuna ukuvikela izinhlelo zabo ze-PV kusuka kumonakalo owenziwe ngombani.
Ngokufanayo, ezindaweni zezimboni, lapho ukuthembeka kwezizukulwane zamandla kubaluleke kakhulu, insiza ye-JCSPV iqinisekisa ukuthi izinhlelo ze-PV ziyaqhubeka zisebenza kahle ngisho nangezimo sezulu ezingezinhle. Ukwakhiwa kwayo okuqinile nokusingathwa kwamandla aphezulu kwenza kubekelwe kahle ukufakwa okulinganiselwe, ukuqinisekisa ukuthi amabhizinisi angagcina ukunikezwa kwamandla angaphazanyiswa futhi agweme ukuphazamiseka okukhona kokusebenza.
Isiphetho: Ukuvikela ikusasa lamandla avuselelekayo
Ekuphetheni,Idivaysi yokuvikela i-jcsppt photovoltaic SurgeIdlala indima ebaluleke kakhulu ekuqinisekiseni ukuphepha nokwethenjwa kwezinhlelo ze-PV. Ngokuhlinzeka ngokuvikelwa okuphakeme ekulweni kwama-Lightning Surge Volporages, le divayisi evikela izingxenye ezibucayi, inciphisa izindleko zokulungisa nokubuyisela esikhundleni, futhi inweba isikhathi sokuphila se-PV
Ngezici zayo ezithuthukile, ukuhambisana namazinga aphesheya, kanye nezicelo eziguquguqukayo, idivaysi yokuvikela i-JCSPV iyisici esisemqoka kunoma yikuphi ukufakwa kwe-PV. Ngokukhetha i-JCSPV Photovoltaic Surge Vikela ukuvikela, abanikazi bohlelo lwe-PV bangaqiniseka ukuthi ukutshalwa kwezimali kwabo kuvikelwe emiphumeleni elimazayo yombani, iveza indlela yekusasa elikhanyayo futhi elizinzile kakhulu kumandla avuselelekayo.
