Yiziphi Izinzuzo Zokushintsha Kwezokuphepha Kwe-PV Firefighter?

   I-PV firefighter switch switchiyisisombululo esisha sokuvala shaqa iphaneli yelanga ehambisana nazo zonke iziguquli zezintambo ezijwayelekile.Njengamanje, ama-photovoltaics asatshalaliswa ophahleni asetshenziswe kabanzi e-China, e-United States, e-Australia, eYurophu naseJapane.Indlela yokuqinisekisa ukuphepha komuntu siqu, indlela yokuvimbela ubungozi bomlilo bezindawo ze-photovoltaic, kanye nendlela yokuqinisekisa ukuthi abangewona ochwepheshe bahlonza futhi banqamule izingozi okokuqala sekuyizinto ezivamile ezikhathazayo kuwo wonke amazwe.I-Slocable ihamba phambili kubuchwepheshe obuthuthukiswe ngokukhethekile emakethe yamandla avuselelekayo, ikakhulukazi amandla elanga, ehlangabezana nezidingo zokushintshashintsha kwe-DC okuphephile nokusebenza kahle, okuhlangabezana nezindinganiso eziphakeme kakhulu zobuchwepheshe nezohwebo.

Kuzinhlelo ze-photovoltaic, kunezingozi ezimbili zokuphepha: "ingozi ye-DC high voltage" kanye "nengozi yokuhlenga".Kuhlelo lochungechunge lwendabuko, ingqikithi yamandla kagesi yawo wonke umugqa wochungechunge ingafinyelela ku-600V ~ 1000V.Ngenxa yokuxhumana okuxekethile kwezixhumi ze-photovoltaic, ukuthintana okungalungile, izintambo ezimanzi, nokuqhuma kwe-insulation, kulula ukubangela i-DC arcing, engase ibangele umlilo.Ngaphezu kwalokho, lapho ingozi yomlilo ivela ngenxa yokudonsa i-arc noma izimbangela zangaphandle, esimweni sohlangothi lwe-DC, okwamanje kukhiqizwa inqobo nje uma kukhona ingxenye yokukhanya.I-voltage ephezulu ihlala ikhona.Ukucisha umlilo kuyingozi kakhulu futhi izicishamlilo azikwazi ukuhlenga indawo yesigameko futhi zingakwazi ukulawula umlilo kuphela ukude.

I-Slocable yethule ukushintshwa kwe-isolator ye-DC kanye nokushintsha kokuphepha kwesicishamlilo se-PV ngokuya ngesidingo semakethe.Ezinhlelweni eziningi ze-PV,I-DC inqamula amaswishiahlanganiswe ku-inverter yamandla e-DC/AC, futhi injongo yawo eyinhloko ukunqamula i-inverter DC ngesikhathi sokulungiswa, kodwa ayikwazi ukwenza lutho nge-DC (600 ~ 1500V) kusukela ophahleni kuya esigabeni se-inverter.Izintambo eziphakathi kwamamojula elanga e-DC kanye neziguquli zamandla kagesi e-DC/AC zisangaphansi kwe-VDC efinyelela ku-1000 ngenkathi zisebenza ngaphakathi kwesakhiwo ngemva kokuba inkinobho yokunqamula i-DC ivaliwe.Uma kwenzeka kuba nomlilo, izicishamlilo zingachayeka ezingozini ezimbi kakhulu ezingase zibe khona.

Umshini wokuphepha we-Slocable firefighter uhlinzeka ngesixazululo lapho izicishamlilo zinqamula isifunda samandla e-AC ngaphambi kokucisha umlilo ukuze ziqale ukulwa nomlilo ngaphandle kwengozi yokucisha ugesi.I-switch yokuphepha komlilo ibona ukwehluleka kwegridi futhi ivala ngokuzenzakalelayo inkinobho ye-isolator ngemva kwemizuzwana engu-5, idale indawo ephephile yabacimi bomlilo.(Amandla e-AC avaliwe = amandla e-DC acisha ngokuzenzakalelayo; setha kabusha ngokuzenzakalelayo lapho amandla e-AC ebuyiselwa = ukutholwa kwamandla e-DC) Isistimu yokushintsha ukuphepha kwesicishamlilo se-PV singanqanyulwa ngokushesha, ngokuphelele futhi ukude ekufakweni kwe-PV ngesenzo esilula kusixhumi esibonakalayo sephaneli yokulawula, futhi ingenziwa icushwe ukude ngenethiwekhi yomakhalekhukhwini.Ngokunqamula ukufakwa kwe-PV, awekho amandla e-DC aqhutshwa ku-PV array, futhi amandla e-DC aphezulu-voltage avela kumamojula we-PV azohlukaniswa ngokuphelele, okuhlinzeka ngezimo eziphephile zokucisha umlilo futhi bangene esakhiweni.

Ubuhle beSlocable PV Firefighter Safety Switch/Rapid Shutdown switch:

1. Uhlu olubanzi lwemikhiqizo ukuhlangabezana nezidingo zezimo ezihlukahlukene zokusebenza
2. Ifanele isistimu ye-photovoltaic engu-600V/1000V/1500V
3. Okubanzi nokukhudlwana kwamanje: kufika ku-40A
4. Ububanzi be-voltage ye-AC ebanzi 100~270V AC
5. Ukunqanyulwa kweswishi eshayelwa yimoto
6. Isikhombi se-LED, VULIWE noma VALIWE singasibona kalula isimo
7. Ibanga le-IP65, lilungele ngokuphelele ukufakwa ngaphandle
8. Knock out |isixhumi sekhebula |Isixhumi se-MC4 / 1m ikhebula le-AC ngokuzithandela, lilungele ukufakwa kwamakhasimende
9. Ifakwe i-valve yokuphefumula ukugwema ukujiya kwe-condens ngaphakathi kwendawo ebiyelwe
10. Inzwa yezinga lokushisa eyakhelwe ngaphakathi, ukuvala shaqa okuzenzakalelayo lapho kungaphezu kuka-80°C
11. Umsindo ophansi ngesikhathi sokusebenza, awuphazamisi impilo evamile yabantu
12. Umklamo we-Modular wezingxenye zomkhiqizo, ukugcinwa okusheshayo nokulula ngemva kokuthengisa

Ngokusebenza okuhle kakhulu, isikhathi sokulethwa okusheshayo kanye nethimba lochwepheshe emva kokuthengisa ukuze liphendule ngokushesha izidingo zamakhasimende, ukushintshwa kokuphepha komlilo we-Slocable kudayisa kahle emakethe yaseYurophu futhi kuyaqhubeka nokwamukelwa kahle ngamakhasimende.

Nakuba sinemigqa yokukhiqiza ezenzakalelayo yokukhiqiza ngobuningi kanye nohlu oluphelele lwezixazululo ezijwayelekile, amakhasimende ethu nawo anezidingo ezikhethekile ezenziwe ngokwezifiso, futhi sizosebenzisana nalawa makhasimende ukuthuthukisa isisombululo esingcono kakhulu sezidingo zabo.

Izidingo eziqondene nekhasimende zingahluka ngokuhlanganisa okuthile kwezinto ezikhona, kodwa zingase futhi zibandakanye ukwakhiwa kwamafindo akhethekile noma izindlela.I-Slocable iyakwazi ukuhlinzeka amakhasimende ngesevisi ebanzi kakhulu, sineqembu lonjiniyela, abaklami kanye nochwepheshe.

I-NEC2017 idinga ukufakwa kwe-PV kuwo wonke amabhilidi ukuze kufinyelele ngokushesha ukuvalwa kweleveli yemojuli ezimeni eziphuthumayo.I-NEC 2017 690.12 nayo inezidingo eziqinile zokushintshwa kokuvala shaqa okusheshayo.Ibanga elingaphakathi kuka-305mm ukusuka kuhlelo lwe-photovoltaic liwumngcele.Phakathi neminyaka engu-30 ngemva kokuba idivayisi yokucisha ngokushesha iqalisiwe, i-voltage ye-array engaphandle komngcele yehla ngaphansi kuka-30V, futhi i-voltage ngaphakathi komngcele yehla ngaphansi kuka-80V, okungukuthi, ukuvalwa kwezinga lephaneli kuyadingeka.Le mfuneko iqale ukusebenza ngoJanuwari 1, 2019.

Ngemva kokufaka inkinobho yokuphepha ye-PV firefighter, imodyuli ngayinye ye-photovoltaic ingahlukaniswa ukuze igweme ingozi ye-voltage ephezulu.Uma kwenzeka umlilo, i-voltage ephumayo ye-module inganqanyulwa ngesikhathi sokuqala ukuze kuqinisekiswe ukuphepha kwabacimi bomlilo.

Ungayikhetha Kanjani Imodeli Yokushintsha Kokuphepha Kwesicishamlilo Esilungile:

1. Qinisekisa i-voltage kanye namanje okudingekayo ohlelweni lwe-photovoltaic
2. Izidingo ze-Interface: Knockouts |Izindlala zekhebula |Isixhumi se-MC4 ngokuzithandela
3. Ikhebula le-AC eliyimitha eli-1 liyadingeka noma cha
4. 1~5 izintambo ezitholakalayo
