Wopanga Wapamwamba kwambiri wa DC Circuit Breaker

CDADAndi opanga odalirika komanso ogulitsa ma DC ophwanya ma circuit. Zogulitsa zathu ndizapamwamba, zodalirika, komanso zaukadaulo. Timakhazikika pakupanga mayankho ogwirizana ndi mafakitale monga mphamvu zatsopano, kukupatsirani ntchito zonse za OEM zokhazikika.

Kodi DC Circuit Breaker ndi chiyani?

A DC circuit breaker ndi chipangizo chapadera chodzitchinjiriza chomwe chimapangidwira kusokoneza mabwalo apano (DC) omwe ali ndi zinthu zambiri, zofupikitsa, kapena zolakwika. Mosiyana ndi ma AC ophwanya ma AC omwe amapindula ndi kuwoloka kwachilengedwe kwa ziro (nthawi 100-120 pa sekondi iliyonse pa 50/60Hz), zophulitsa DC ziyenera kuzimitsa mwamphamvumosalekeza, unidirectional arc zomwe zilibe chibadwa chozimitsa chokha. Kusiyana kwakukuluku kumafuna matekinoloje apamwamba kwambiri oziziritsira ma arc, kupangitsa kuti zophulika za DC zikhale zazikulu, zovutirapo, komanso zodula kuposa anzawo a AC.

Ma circuit breaker a DC amagwira ntchito modutsa ma voltages osiyanasiyana12V mpaka 1500V DC, ndi mavoti omwe alipo panopa2A mpaka 2500A. Amagwira ntchito ngati zida zodzitetezera pamakina a solar photovoltaic (PV), makina osungira mphamvu za batri (BESS), galimoto yamagetsi (EV) yopangira infrastru.cture, malo opangira data omwe ali ndi magetsi a DC, zowongolera zamagalimoto a DC zamafakitale, ndi makina amagetsi apanyanja.

Vuto lalikulu pakusokoneza kwa DC lili mkatiarc extinction physics: Ma arcs a DC amasunga mizati ya plasma yokhazikika yotentha yopitilira 10,000 ° C, yomwe imafunikira kukweza mokakamiza, kuziziritsa, ndikuchotsa maginito, ma arc chutes, ndi zida zapadera zolumikizirana.

Magnetic Blowout Physics

The Lorentz force equation imayang'anira kusintha kwa DC arc:

F = Ine × L × B

Kumene:

F = Mphamvu pa arc (Newtons)

I = Arc current (Amperes)

L = Arc kutalika (mita)

B = Magnetic flux density (Tesla)

Kuwerengera Chitsanzo:

Arc yapano: 1000A

Kutalika kwa Arc: 0.02m (2cm)

Mphamvu yamagetsi: 0.2T

Mphamvu: F = 1000 × 0.02 × 0.2 = 4N

Kuthamanga: a = 4N / (5×10⁻⁴ kg/m × 0.02m) = 400,000 m/s²

Kuthamanga kwakukuluku kumayendetsa arc kukhala mbale zogawanika mkati mwa milliseconds, pomwe imagawika, kuziziritsidwa, ndi kuzimitsidwa.
