250V DC Miniature Circuit Breaker

Khusela iisekethe zakho ze-DC kunye ne-CDADA DAB7-63 250V DC Miniature Circuit Breaker (MCB) - ireyithwe ukuya kuthi ga kwi-250V DC, yenziwe ngobunjineli yi-Shanghai DADA Electric CO., LTD, umzi-mveliso othembekileyo e-China, ngenxa yomthwalo othembekileyo kunye nokhuseleko lwesiphaluka kwi-photovoltaic yelanga yanamhlanje (PV), unxibelelwano lwe-telecommunications, ukugcinwa kwebhetri, i-DC.

Ngokungafaniyo neziqhekezi eziqhelekileyo ze-AC, i-DAB7-63 yenzelwe ngokukodwa izicelo ze-DC, apho ukuphela kwe-arc kunzima kakhulu ngenxa ye-voltage polarity rhoqo. Ngomthamo ophezulu wokuphulwa kwe-6,000A kwi-DC 250V, iphazamisa ngokukhawuleza imisinga ephosakeleyo ukukhusela umonakalo ovela kwi-reverse yangoku, impendulo ye-inverter, okanye iiphoso zentambo-okwenza ukuba ibe yinto ebalulekileyo yokhuseleko kwindawo yokuhlala kunye neyorhwebo ufakelo lwelanga.

Ifumaneka kwi-13 yangoku yokulinganisa (1A-63A) kunye noqwalaselo lwe-1P ye-250V DC, iphinda ilinganise kwi-2P (500V), i-3P (750V), kunye ne-4P (1000V) ye-PV ephezulu-voltage arrays. I-breaker ifaka iinketho ezimbini ze-wiring (intambo okanye i-busbar), isalathisi esicacileyo sendawo yoqhagamshelwano, kunye ne-fast-make / fast-break-break-breaking mechanismd for enhanced arc suppression. Ukuthobela ngokupheleleyo i-IEC 60947-2, IEC 60947-8, CCC, kunye ne-EU RoHS, iqinisekisa ukhuseleko lwehlabathi kunye nemigangatho yokusingqongileyo.

FAQ

I-Q1: Ndingasebenzisa i-AC MCB yeesekethe ze-DC 250V?

I-A1: Hayi. Abaphuli be-AC baxhomekeke kwi-zero-cross ukucima i-arcs-DC ayinayo i-zero-crossing, ngoko ke i-arcs iphikelela, ibangela ukunyibilika, umlilo, okanye ukungaphumeleli ukuhamba. Soloko usebenzisa i-MCB ekwi-DC efana ne-CDADA DAB7-63.

I-Q2: Ngaba i-polarity ibalulekile?

A2: Ewe! I-DAB7-63 250V DC Miniature Circuit Breaker ichaze igalelo (amandla +/–) kunye nemveliso (L+/L–) iitheminali. Ukubuyisela umva i-polarity kunciphisa ukusebenza kakuhle kokucima i-arc kwaye kunokuphelisa isiqinisekiso sokhuseleko.

Q3: Uthini umahluko phakathi kwe-1P, 2P, kunye ne-4P DC MCBs?

A3:

● I-1P: Ikhusela umqhubi omnye kwi-250V DC (umzekelo, umgca ochanekileyo kwinkqubo ye-PV esekelwe phantsi)

● I-2P: Iqhekeza zombini + kunye - kwi-500V DC (iinkqubo ezidadayo)

● 4P: Kwiintambo ze-1000V DC (izityalo ezinkulu zePV zorhwebo)

→ Soloko uthelekisa ukubala kwepali kumbane wenkqubo yakho kunye neskim sokumisa.

I-Q4: Ngaba ingasetyenziselwa ukutshintsha rhoqo?

I-A4: Hayi-yenzelwe ukusebenza ngokungaqhelekanga ngesandla (umzekelo, ukugcinwa). Ukutshintsha kwemihla ngemihla, sebenzisa i-DC contactor okanye ifowuni yokulayisha.

Q5: Kutheni ukhetha CDADA ngaphezu kwezinye iimpawu DC MCB?

A5: CDADA inikeza:

● Uyilo lophazamiseko lwe-arc lwenyani lwe-DC (alulungiselelwanga i-AC)

● Isiqinisekiso esipheleleyo se-IEC + CCC

● Isalathisi esicacileyo semo yembonakalo

● Uluhlu olubanzi lwangoku (1A–63A) lokulinganisa okuchanekileyo

● Amaxabiso akhuphisanayo namaxwebhu obugcisa esiNgesi
