Kodi PV Array DC Isolator Switch Imateteza Bwanji Photovoltaic System?

       PV array DC isolator switch, monga momwe dzinalo likusonyezera, ndi chosinthira chomwe chimapatula DC.Amagwiritsidwa ntchito kwambiri pamakina opangira magetsi a photovoltaic, ndipo amagwiritsidwa ntchito pakati pa ma high-voltage DC photovoltaic arrays ndi ma grid-connected inverters kuti adule ma arcs opangidwa ndi mphamvu ya DC, kupewa ngozi zoopsa, ndikuonetsetsa kuti ntchito ikuyenda bwino.Zili pafupi ndi inverter ndipo zimafunikira njira yodzipatula pamanja gulu lonse la PV pakukhazikitsa dongosolo kapena kukonza kwina kulikonse.

Kodi Ntchito Zachitetezo za PV Array DC Isolator Switch ndi ziti?

(1) Poika pulogalamu ya photovoltaic, woyikirayo nthawi zambiri amazimitsa chosinthira cha DC choyamba kuti alekanitse kulowetsa kwa solar panel kuchokera ku inverter.Panthawi ya mawaya ndi plugging ya ma terminals a DC, mphamvu ya DC siyimalumikizidwa ku mbali ya DC ya inverter kuti ateteze kugwedezeka kwamagetsi kwamunthu komanso kuwonongeka kwa zida zosinthira ndi kumbuyo.Chifukwa chake, pakuyika makinawa, timafunikira PV array dc isolator kuti tisiyanitse mphamvu ya DC pakati pa inverter ndi gulu la batri.

(2) Pamalo opangira magetsi a photovoltaic, inverter ndi "core center".Pofuna kutsimikizira nthawi yokwanira yopanga mphamvu, inverter ilibe batani loyambira.Malingana ngati pali kuwala (ngakhale nyengo yamvula), ma solar panels amatha kupanga magetsi ndipo inverter imatha kugwira ntchito yokha.Komabe, izi zimabweretsanso vuto.Mukasintha kapena kukonza inverter, ngakhale mbali ya AC idalumikizidwa ndi chowotcha chamagetsi cha AC, mbali ya DC imakhala yamphamvu nthawi zonse.Pankhaniyi, ngati inverter ilibe solar array dc isolator switch kuti isiyanitse mphamvu ya DC ya mapanelo, ndikosavuta kuyambitsa kugwedezeka kwamagetsi ndi kuwonongeka kwa zida.

(3) Pakalipano, ma inverters ambiri pamsika ndi a TL mndandanda, ndiko kuti, palibe magetsi odzipatula mkati, ndipo pali mwayi wobwerera kumbuyo kuchokera ku mbali ya AC kupita ku mbali ya DC.Pakukonza, ngati chosinthira cha AC ndi chosinthira cha DC chili patali, chimatha kutetezedwa bwino.

Mitundu Yosiyanasiyana Yoyikira

Pali mitundu 5 yoyikapo: Mtundu woyikira dzenje limodzi, mtundu woyikira gulu, mtundu wa njanji, mtundu woyika pachitseko, ndi mtundu woyikira kunja.

Mawonekedwe a Slocable PV Array DC Isolators:

1. Zopangidwa makamaka kuti zigwiritsidwe ntchito pa DC, zidavotera pakali pano 16 ~ 630A, mtundu wamagetsi: ≤1500V, oyenera ntchito zosiyanasiyana;

2. Njira zoyikira zosiyanasiyana ndi kapangidwe kake zimapatsa kusinthasintha kwa unsembe wazinthu;

3. Magetsi odziyeretsa okha, amachepetsa kukana ndi kugwiritsa ntchito mphamvu, komanso amatalikitsa moyo wautumiki;

4. Chiwerengero cha mizati: 2 ~ 10 misinkhu kusankha;

5. Nthawi yopuma: zosakwana 5ms

6. Zida za UL94V-0 zomwe zimatumizidwa kunja zimagwiritsidwa ntchito, zomwe zingagwiritsidwe ntchito m'malo ovuta;

7. Tsatirani mfundo zosiyanasiyana (monga IEC, UL, TUV, CE, CB, SAA, CCC, etc.)

Slocable imatha kupanga ma PV array isolator oyenerera ma inverters a zingwe kuyambira 1KW mpaka 320KW.Ndiwogulitsa ma switch odzipatula a DC potsatira IEC60947-3(ed.3.2):2015 ndipo walandira chiphaso cha UL.

Zogulitsazi zomwe zikugwirizana ndi mfundo zamakono za photovoltaic zimatha kukwaniritsa zosowa zazikulu za msika wa photovoltaic padziko lonse ndipo zimatha kuthetsa nkhawa za makasitomala pa chitetezo ndi chitetezo.Slocable ipitiliza kuchita kafukufuku wozama kuti apatse msika zisankho zamitundumitundu komanso zabwinoko.
