I-PV Array DC Isolator Switch Ivikela Kanjani Uhlelo Lwe-Photovoltaic?

       I-PV array DC isolator switch, njengoba negama liphakamisa, iyiswishi ehlukanisa i-DC.Isetshenziswa kakhulu ezinhlelweni zesiteshi samandla e-photovoltaic, futhi isetshenziswa phakathi kwe-high-voltage DC photovoltaic arrays kanye nama-inverters axhunywe kugridi ukusika ama-arcs akhiqizwa amandla e-DC, ukugwema izingozi eziyingozi, nokuqinisekisa ukusebenza okuphephile.Atholakala eduze kwe-inverter futhi adinga indlela yokuhlukanisa mathupha lonke uhlobo lwe-PV phakathi nokufakwa kwesistimu noma noma yikuphi ukulungiswa okulandelayo.

Iyini Imisebenzi Yokuvikela ye-PV Array DC Isolator switch?

(1) Lapho ufaka isistimu ye-photovoltaic, isifaki ngokuvamile sivala iswishi ye-DC kuqala ukuze sihlukanise okokufaka kwephaneli yelanga ku-inverter.Phakathi nalokhu kufakwa kwezintambo nokuxhunywa kwamatheminali e-DC, amandla e-DC awaxhunywanga ohlangothini lwe-DC lwe-inverter ukuvimbela ukushaqeka kukagesi komuntu siqu kanye nokulimala kwe-inverter kanye nemishini yokuvala emuva.Ngakho-ke, lapho sifaka isistimu, sidinga isihlukanisi se-PV array dc ukuze sihlukanise amandla e-DC phakathi kwe-inverter nephaneli yebhethri.

(2) Esiteshini samandla e-photovoltaic, i-inverter "isikhungo esiyinhloko".Ukuze kuqinisekiswe isikhathi esanele sokukhiqiza amandla, isiguquli asinayo inkinobho yokuqala yokumisa.Uma nje kunokukhanya (ngisho noma kunezulu), amaphaneli elanga angakhiqiza ugesi futhi i-inverter ingasebenza ngokuzenzakalelayo.Nokho, lokhu futhi kuveza inkinga.Uma ushintsha noma ulungisa i-inverter, nakuba uhlangothi lwe-AC lunqanyuliwe yi-AC circuit breaker efakiwe, uhlangothi lwe-DC luhlala lunamandla.Kulokhu, uma i-inverter ingenayo i-solar array dc isolator switch ukuze ihlukanise amandla e-DC amaphaneli, kulula ukubangela ukushaqeka kukagesi kanye nokulimala kwemishini.

(3) Njengamanje, ama-inverter amaningi emakethe ochungechunge lwe-TL, okungukuthi, akukho ukuhlukaniswa kukagesi ngaphakathi, futhi kukhona ithuba lokugeleza okuhlehlayo ukusuka ohlangothini lwe-AC kuya ohlangothini lwe-DC.Ngesikhathi sokulungiswa, uma iswishi ye-AC kanye neswishi ye-DC kubekwe zodwa ngokomzimba, ingavikeleka ngokuphephile.

Izinhlobo Zokufaka Ezihlukene

Kunezinhlobo ezi-5 zokufaka: Uhlobo lokukhweza lwembobo eyodwa, uhlobo lokukhweza Iphaneli, uhlobo lokukhweza ujantshi, Uhlobo lokukhweza ukhiye womnyango, kanye nohlobo lokukhweza lwangaphandle.

Izici ze-Slocable PV Array DC Isolators:

1. Iklanyelwe ikakhulukazi isicelo se-DC, ilinganiswe uhla lwamanje 16 ~ 630A, ububanzi be-voltage: ≤1500V, ifanele izinhlelo zokusebenza ezihlukahlukene;

2. Izindlela zokufaka ezihlukene kanye nokwakheka kwemodular kunikeza ukufakwa komkhiqizo ukuguquguquka;

3. Idizayini yokuzihlanza yokushaqeka kukagesi, inciphisa ukumelana nokusebenzisa amandla, futhi yandise impilo yesevisi;

4. Inani lezigxobo: 2 ~ 10 amazinga ozikhethela;

5. Isikhathi esiphezulu sokuvala: ngaphansi kuka-5ms

6. Kusetshenziswa izinto ezikhiqizwe amalangabi ze-UL94V-0 ezingenisiwe, ezingasetshenziswa ezindaweni ezisetshenziswayo ezinokhahlo;

7. Ukuthobela izindinganiso ezihlukahlukene (njenge-IEC, UL, TUV, CE, CB, SAA, CCC, njll.)

I-Slocable ingakhiqiza ama-PV array isolator afanele uhla olugcwele lwama-inverter ezintambo ukusuka ku-1KW kuya ku-320KW.Ingumphakeli wamaswishi e-DC isolator ngokuthobela i-IEC60947-3(ed.3.2):2015 futhi ithole isitifiketi se-UL.

Le mikhiqizo ethobelana namazinga akamuva e-photovoltaic ingahlangabezana nezidingo ezibanzi zemakethe ye-photovoltaic yomhlaba wonke futhi ingaxazulula ukukhathazeka kwamakhasimende mayelana nokuphepha nokuvikelwa kwesistimu.I-Slocable izoqhubeka nokwenza ucwaningo olujulile ukuze inikeze imakethe izinketho eziningi ezihlukene nezingcono.
