250V DC Miniature Circuit Breaker

Tetezani mabwalo anu a DC ndi CDADA DAB7-63 250V DC Miniature Circuit Breaker (MCB) - yovotera mpaka 250V DC, yopangidwa ndi Shanghai DADA Electric CO., LTD, fakitale yodalirika ku China, yodalirika yochulukira komanso chitetezo chanthawi zazifupi pamakina amakono a solar photovoltaic (PV), matelefoni, makina osungira mabatire a DC.

Mosiyana ndi ma breaker wamba a AC, DAB7-63 idapangidwira ma DC, pomwe kutha kwa arc kumakhala kovuta kwambiri chifukwa cha polarity yosalekeza. Ndi mphamvu yosweka kwambiri ya 6,000A pa DC 250V, imasokoneza mofulumira mafunde olakwika kuti ateteze kuwonongeka kwaposachedwa, mayankho a inverter, kapena zolakwika za zingwe-kupangitsa kuti ikhale chigawo chofunikira cha chitetezo m'malo okhala ndi malonda a dzuwa.

Ikupezeka m'magulu 13 apano (1A-63A) ndi masinthidwe a 1P a 250V DC, imafikiranso ku 2P (500V), 3P (750V), ndi 4P (1000V) pama PV amphamvu kwambiri. Chowotchacho chimakhala ndi njira ziwiri zamawaya (chingwe kapena busbar), chizindikiritso chodziwika bwino cha malo, ndi njira yopangira mwachangu/yopumira kuti apititse patsogolo kuponderezana kwa arc. Kugwirizana kwathunthu ndi IEC 60947-2, IEC 60947-8, CCC, ndi EU RoHS, imatsimikizira chitetezo padziko lonse lapansi komanso miyezo yachilengedwe.

Zofunika Kwambiri

Chithunzi cha Wiring

Miniature DC circuit breaker ndondomeko ndi kukula kwake

Chifukwa Chiyani Sankhani CDADA DC MCB 250V?

★ Cholinga-chomangidwa kwa DC Systems

Mapangidwe okhathamiritsa a arc chute amawonetsetsa kusokonezeka kwa mafunde a DC motetezeka - mosiyana ndi zophulika za AC zomwe zidakonzedwanso.

★ Solar PV Yakonzeka

Zofunikira pakuteteza ma module a PV kuti asabwererenso kulephera kwaposachedwa komanso kulephera kwa inverter - kumawonjezera kudalirika kwadongosolo.

★ Kuthamanga Kwambiri Kwambiri

6kA pa 250V DC imakwaniritsa zofunikira pakukhazikitsa nyumba zambiri komanso zazing'ono zamadzuwa.

★ Global Certification

IEC + CCC + RoHS = magwiridwe antchito odalirika ku Asia, Europe, Africa, ndi Latin America.

★ Mapangidwe Otetezeka Ogwiritsa Ntchito

Chotsani kukhudzana ndi zenera kumalepheretsa misoperation; mawaya apawiri amathandizira kuphatikiza mapanelo.

★ Wide Operating Range

Imagwira ntchito modalirika kuyambira -35 ° C (nyengo yozizira) mpaka +70 ° C (madenga otentha kapena m'malinga).

Chifukwa chiyani kusankha CDADA?

★ Ndife opanga zaka zopitilira 42. Kampani yathu yomwe idamangidwa mu 1983, ikukula mwachangu kwambiri pazaka zapitazi. Ndi zinthu zopitilira 1000, takhala tikupanga ndikupanga makina athu ozungulira omwe amakhala mozungulira pashelufu ya OEM yophwanya ma circuit breaker ndi zisindikizo. Timapanga lingaliro latsopano kuti tipange ophwanya madera achimuna osiyanasiyana kuti athandizire zosowa za makasitomala.

★ Tili ndi zaka zopitilira 42, tili ndi zida zamapangidwe amkati ndi zopangira zosinthira mwachangu, zabwino.

★ Tili ndi gulu loyankha mwachangu kwambiri. Mafunso adayankhidwa mkati mwa tsiku limodzi logwira ntchito, 3D idayankha mkati mwa tsiku limodzi logwira ntchito.

★ Kunyamula

Makasitomala athu ambiri amatipatsa zomwe zalembedwa kapena zoyika pazithunzi zawo. Tingakhale okondwa kugwira ntchito nanu kuti mukwaniritse zomwe mukufuna.

★ Chiwonetsero champhamvu chamagetsi padziko lonse lapansi cha Power Gen

Chiwonetsero chathu chimakwirira padziko lonse lapansi, Dubai, Brazil, Russia, Hanover, Egypt, Austria, Iran, Mexico ndi ziwonetsero zina zamaluso

FAQ

Q1: Kodi ndingagwiritse ntchito AC MCB kwa mabwalo a DC 250V?

A1: Ayi. Ophwanya AC amadalira zero-kuwoloka kuti azimitse arcs-DC ilibe zero-kudutsa, kotero ma arcs amapitirizabe, kuchititsa kusungunuka, moto, kapena kulephera kuyenda. Nthawi zonse gwiritsani ntchito MCB yokhala ndi DC ngati CDADA DAB7-63.

Q2: Kodi polarity ndi yofunika?

A2: ndi! DAB7-63 250V DC Miniature Circuit Breaker ili ndi malo olowera (mphamvu +/–) ndi zotuluka (L+/L–). Kubwezeretsanso polarity kumachepetsa mphamvu ya arc kuzimitsa ndipo kungalepheretse chiphaso chachitetezo.

Q3: Kodi pali kusiyana kotani pakati pa 1P, 2P, ndi 4P DC MCBs?

A3:

● 1P: Imateteza kondakitala mmodzi pa 250V DC (mwachitsanzo, mzere wabwino mu dongosolo la PV)

● 2P: Amaphwanya zonse + ndi – pa 500V DC (makina oyandama)

● 4P: Kwa zingwe za 1000V DC (zomera zazikulu zamalonda za PV)

→ Nthawi zonse fananizani kuwerengera kwa ma voltage ndi dongosolo lanu loyambira.

Q4: Kodi angagwiritsidwe ntchito kusintha pafupipafupi?

A4: Ayi - idapangidwa kuti izigwira ntchito pafupipafupi (mwachitsanzo, kukonza). Pakusintha kwatsiku ndi tsiku, gwiritsani ntchito cholumikizira cha DC kapena chosinthira.

Q5: Chifukwa chiyani kusankha CDADA pa zina DC MCB zopangidwa?

A5: CDADA imapereka:

● Zowonadi za DC arc zosokoneza (zosasinthidwa ndi AC)

● Chitsimikizo chonse cha IEC + CCC

● Chowonetseratu chowonetseratu

● Kusiyanasiyana kwamakono (1A–63A) kuti musanthule bwino

● Mitengo yampikisano yokhala ndi zolemba zaukadaulo mu Chingerezi
