BYM3DC Series 1500V Photovoltaic Molded Case Circuit Breaker

Izi Mlandu Wophwanyidwa Wozungulira imaphatikiza njira zodzitetezera zotsogola zofunika kwambiri pakupanga mphamvu zongowonjezwdwa. Imakhala ndi chitetezo chochedwetsa chokhazikika chomwe chimalepheretsa kuwonongeka kwa ma conductor kuchokera ku ma overcurrents osatha, limodzi ndi chitetezo chanthawi yochepa chomwe chimayenda mkati mwa ma milliseconds pazochitika zolakwika. Thermal-magnetic tripping mechanism imagwira ntchito mopanda mphamvu zakunja, kuwonetsetsa kuti imagwira ntchito molephera panthawi yamavuto a gridi. Ndi ntchito zonse ziwiri zomwe zidakhazikitsidwa ku IEC, wophwanya amapereka chitetezo cholumikizidwa pamabokosi ophatikizira a PV, zolowetsa inverter, ndi makina osungira mabatire.

Imapezeka m'mapangidwe onse a 2-pole (2P) ndi 3-pole (3P), BYM3DC imagwirizana ndi zomangamanga zosiyanasiyana. Kapangidwe kophatikizika kamene kamapangitsa kuti pakhale malo apakati ndikusunga chilolezo chodzipatula cha 1500V. Nyumba yake yokhala ndi fiberglass yolimbitsa ma thermoset imapereka mphamvu zapadera za dielectric komanso kukana kuwonongeka kwa UV, kutentha kwambiri (-25 ° C mpaka +70 ° C), komanso malo owononga. Dongosolo lozungulira lopumira pawiri limakwanitsa kuzimitsa mwachangu kudzera pakupatuka kwa maginito, komwe kuli mkati mwa ma arc chute omata omwe amalepheretsa kuthawa kwa plasma.

Kutsatira miyezo yapadziko lonse lapansi ya photovoltaic (IEC 60947-2, UL 489B) imatsimikizira uinjiniya wachitetezo cha wophwanyayo. The Mlandu Wophwanyidwa Wozungulira imaphatikizanso njira zotsimikizira zoyeserera zomwe zimalola kutsimikizira kotetezeka kwa magwiridwe antchito omwe ali ndi katundu. Bokosi lake losindikizidwa losindikizidwa katatu limalepheretsa kulowetsa kwa fumbi/ chinyezi (IP40), pomwe zomangira za torque-limited terminal zimalepheretsa kuwonongeka kwa conductor pakuyika. Kupirira kwamakina osweka kumapitilira ntchito 10,000 pakali pano, kuwonetsetsa kuti zaka makumi ambiri zantchito zopanda kukonza m'malo ovuta.

BYM3DC photovoltaic DC breaker ndiyofunikira pakuyika kwamakono kwa solar. Imateteza mikangano yovuta pakati pa zingwe za PV ndi ma inverters, imateteza mabanki a batri m'makina osungira, ndikupatula zolakwika pamagawo ogawa a DC. Mainjiniya amafotokozera yankho lake pakuphatikiza kwake kwamphamvu kwamagetsi (1500VDC), mphamvu yapano ya 800A, komanso ukadaulo wodzipatulira wa DC womwe umapereka chitetezo champhamvu, chogwirizana ndi malamulo ofunikira pamafamu oyendera dzuwa, madenga a mafakitale, ndi mapulojekiti ang'onoang'ono padziko lonse lapansi.
