Chifukwa Chiyani DC Circuit Protection Ikukhala Yofunika Patsogolo Lamagetsi Amagetsi?

Makampani opanga mphamvu padziko lonse lapansi akudalira kwambiri pakali pano. Ma solar photovoltaic arrays, makina osungira mphamvu za batri, malo opangira magalimoto amagetsi, zida zolumikizirana ndi matelefoni, ndi malo opangira data zonse zili ndi magawo ofunikira a DC. Pamene mapulogalamuwa akukulirakulira, chitetezo cha dera chikusuntha kuchoka ku gawo lothandizira kupita ku gawo lapakati la chitetezo cha dongosolo. ADC circuit breakerAyenera kutulutsa mphamvu zamagetsi mwachangu komanso mosatekeseka, kuchepetsa kuwonongeka kwa zingwe, zosinthira, mabatire, ndi zida zolumikizidwa.

Kusokoneza DC ndikosiyana mwaukadaulo ndi kusokoneza AC. Mudera la AC, pano mwachilengedwe amawoloka ziro nthawi zambiri pamphindikati, zomwe zimathandiza kuzimitsa arc yamagetsi. DC ilibe zero mwachilengedwe kuwoloka, kotero arc imatha kukhala yokhazikika pambuyo pa kupatukana. Ma breaker opangidwira DC amafunikira zida zolumikizirana, ma arc chute, maginito owulutsira maginito, mtunda wa insulation, ndi ma waya. Wophwanyira AC sayenera kuganiziridwa kuti ndi woyenera ntchito ya DC chifukwa kuchuluka kwake komweku kukuwoneka kokwanira.

Chimodzi mwazinthu zodziwika bwino zamakampani ndikusunthira kumayendedwe apamwamba kwambiri komanso kuchuluka kwamphamvu kwamagetsi. Ma voliyumu apamwamba a DC amatha kuchepetsa mphamvu zamagetsi zomwezo, kuthandiza kutayika kwa ma conductor ndi zofunikira za chingwe. Komabe, zimapangitsanso kulumikizana kwa insulation ndi kusokoneza kwa arc kukhala kofunikira. Kusankha kwazinthu kuyenera kuganiziridwa movotera magetsi ogwirira ntchito, ovoteledwa panopa, kuchuluka kwa mitengo, kutha kwa nthawi yayitali, malo ogwiritsira ntchito, ndi njira yolumikizira yomwe wopangayo wasankha. Zofunikira za polarity ndizofunikira kwambiri pamapangidwe ena a DC breaker.

Chinthu chinanso ndikulumikizana kwapakati pakati pa ophwanya ndi kuyang'anira zamagetsi. Makina amakono amagetsi akugwiritsa ntchito kwambiri masensa, zowongolera, ndi maukonde olumikizirana kuti azindikire kutenthedwa, kuchulukirachulukira, zolakwika zotsekereza, ndi machitidwe osadziwika bwino. Chitetezo pamakina chimakhalabe chofunikira, koma chikukhala gawo lachitetezo chokulirapo chomwe chingaphatikizepo ma fuse, zida zodzitchinjiriza, zolumikizirana, zida zowunikira, ndi makina owongolera mabatire. Kusankha pakati pa zida zakumtunda ndi zotsika kumalandiranso chidwi kwambiri chifukwa kuzimitsa kosafunikira kumatha kukhudza chingwe chonse cha solar, rack yosungirako, kabati yolipira, kapena njira zamafakitale.

Chithunzi cha DAM3DC-250Shanghai Dada Electricikuwonetsa mtundu wa chophwanyira cha DC chomwe chimagwiritsidwa ntchito pogawa kwambiri. Zowoneka bwino zikuwonetsa mphamvu ya 250 A, mphamvu ya DC ya 1000 V, mphamvu yosweka ya 20 kA, ndi mapangidwe awiri. Makhalidwewa amafotokoza zamtundu wake wamagetsi; samadzipangira okha kuyenera kwa kukhazikitsa kulikonse. Mainjiniya akuyenerabe kutsimikizira mulingo wanthawi yayitali, kukula kwa kondakitala, kutentha kozungulira, malo otchingidwa, mawonekedwe olemetsa, kutalika kwa kukhazikitsa, miyezo yoyenera, ndi kulumikizana kofunikira pachitetezo.

Kwa ogwiritsa ntchito mapeto, zilembo zomveka bwino ndi zolemba ndizofunikanso chimodzimodzi, chifukwa kukhazikitsa kolondola, kukonza, ndikusintha zosankha zimadalira kudziwa mavoti otsimikizika a chipangizocho ndi malire ake pautumiki.

Kuyang'ana m'tsogolo, ogula adzagogomezera kwambiri kutsimikizika kwachindunji m'malo mosankha zida ndi mavoti apano okha. Kutetezedwa kodalirika kwa DC kumadalira kufananitsa kwamagetsi koyenera, kusokoneza kokwanira, masinthidwe oyenera, kuyika koyendetsedwa, komanso kuyang'anira pafupipafupi. Pamene m'badwo wongowonjezedwanso, kusungirako, ndi zoyendera zamagetsi zikupitilira kukula, kumvetsetsa izi zithandiza opanga madongosolo kuchepetsa chiwopsezo ndikupanga maukonde odalirika a DC.
