250V DC Miniature Circuit Breaker

Vikela amasekhethi akho e-DC nge-CDADA DAB7-63 250V DC Miniature Circuit Breaker (MCB) - elinganiselwe kufika ku-250V DC, eklanywe i-Shanghai DADA Electric CO., LTD, ifekthri ethembekile e-China, ukuze uthole ukugcwala okuthembekile nokuvikela isifunda esifushane ku-solar photovoltaic yesimanje (PV), ezokuxhumana ngezingcingo, amasistimu ebhethri e-DC.

Ngokungafani nezinqamuli ze-AC ezijwayelekile, i-DAB7-63 yakhelwe ngokukhethekile izinhlelo zokusebenza ze-DC, lapho ukushabalala kwe-arc kuyinselele kakhulu ngenxa ye-voltage polarity engashintshi. Ngomthamo ophezulu wokuphuka we-6,000A ku-DC 250V, iphazamisa ngokushesha imisinga yephutha ukuze ivimbele umonakalo osuka emuva emuva, impendulo ye-inverter, noma amaphutha ezintambo—okuyenza ingxenye yokuphepha ebalulekile ekufakweni kwelanga okuhlala kanye nokuhweba.

Itholakala ezilinganisweni zamanje ezingu-13 (1A–63A) nokucushwa kwe-1P kwe-250V DC, futhi ikala kuya ku-2P (500V), 3P (750V), kanye ne-4P (1000V) ku-PV yamalungu afanayo aphezulu. I-breaker inezinketho zezintambo ezimbili (ikhebula noma ibha yebhasi), inkomba ecacile yendawo yokuxhumana, kanye nendlela yokwenza ngokushesha/ikhefu elisheshayo lokucindezelwa kwe-arc okuthuthukisiwe. Ihambisana ngokugcwele ne-IEC 60947-2, IEC 60947-8, CCC, kanye ne-EU RoHS, iqinisekisa ukuphepha komhlaba wonke namazinga emvelo.

Kungani Khetha i-CDADA DC MCB 250V?

★ Inhloso-Yakhelwe i-DC Systems

Idizayini ethuthukisiwe ye-arc chute iqinisekisa ukuphazamiseka okuphephile kwamafu amaphutha e-DC—ngokungafani nezinqamuli ze-AC ezihloselwe kabusha.

★ Solar PV Ready

Okubalulekile ekuvikeleni amamojula e-PV kusukela ekuphenduleni kokuhlehla kwamanje kanye ne-inverter-ithuthukisa ukwethembeka kwesistimu.

★ High Breaking Umthamo

I-6kA ku-250V DC ihlangabezana nezidingo zezindawo eziningi zokuhlala nezincane zokufakwa kwe-solar.

★ Izitifiketi Zomhlaba Wonke

I-IEC + CCC + RoHS = ukusebenza okuthembekile e-Asia, eYurophu, e-Afrika, naseLatin America.

★ Idizayini ephephile yomsebenzisi

Sula iwindi lesikhundla sothintana naye livimbela ukusebenzisa kabi; izintambo ezimbili zenza kube lula ukuhlanganiswa kwephaneli.

★ Wide Operating Range

Isebenza ngokuthembekile ukusuka ku--35°C (isimo sezulu esibandayo) kuya ku-+70°C (ophahleni olushisayo noma izindawo ezivalekile).

Kungani ukhethe i-CDADA?

★ Singabakhiqizi iminyaka engaphezu kwengu-42. Inkampani yethu eyakhiwa ngo-1983, ikhula ngokushesha okukhulu phakathi neminyaka edlule. Ngezinto ezingaphezu kwe-1000, besiklama futhi senza eyethu i-circuit breaker egxile eduze kwe-OEM ye-air breaker nezimpawu ezingaphandle kweshalofu. Sakha umqondo omusha ukwenza i-circuit breaker yabesilisa ehlukahlukene ukuze sisekele izidingo zamakhasimende.

★ Ngesipiliyoni seminyaka engaphezu kuka-42, sinomklamo wangaphakathi wasendlini kanye nemishini yokukhiqiza yokushintshashintsha okusheshayo, kwekhwalithi.

★ Sineqembu lempendulo esheshayo kakhulu. Imibuzo iphendulwe lungakapheli usuku olungu-1 lokusebenza, i-3D iphendule lungakapheli usuku olungu-1 lokusebenza.

★ Ukupakisha

Iningi lamakhasimende ethu lisinikeza imininingwane yomkhiqizo noma yokupakisha khona kanye kumaphrinti awo edizayini. Singajabula ukusebenza nawe ukuze sifeze izidingo zakho.

FAQ

Q1: Ngingakwazi ukusebenzisa i-AC MCB yamasekhethi e-DC 250V?

I-A1: Cha. Izinqamuli ze-AC zithembele ekuweleni uziro ukuze kucishwe ama-arcs—i-DC ayinawo u-zero-cross, ngakho-ke ama-arcs ayaqhubeka, abangele ukuncibilika, umlilo, noma ukwehluleka ukukhubeka. Njalo sebenzisa i-MCB enesilinganiso se-DC njenge-CDADA DAB7-63.

Q2: Ingabe i-polarity ibalulekile?

A2: yebo! I-DAB7-63 250V DC Miniature Circuit Breaker ichaze amatheminali okokufaka (amandla +/–) nokuphumayo (L+/L–). Ukubuyisela emuva i-polarity kunciphisa ukusebenza kahle kokucisha i-arc futhi kungase kuvimbe nesitifiketi sokuphepha.

Q3: Uyini umehluko phakathi kwe-1P, 2P, kanye ne-4P DC MCBs?

A3:

● 1P: Ivikela ikhondukta eyodwa ku-250V DC (isb., umugqa oqondile kusistimu ye-PV esekelwe phansi)

● 2P: Iphula kokubili + futhi – ku-500V DC (amasistimu antantayo)

● 4P: Ngezintambo ze-1000V DC (izitshalo ezinkulu ze-PV zentengiso)

→ Njalo fanisa ukubalwa kwezigxobo ku-voltage yesistimu yakho nesikimu sokumisa phansi.

Q4: Ingabe ingasetshenziselwa ukushintsha njalo?

I-A4: Cha—iklanyelwe ukusebenza okwenziwa ngesandla okungavamile (isb., ukulungiswa). Ukuze ushintshe nsuku zonke, sebenzisa isixhumi se-DC noma ukushintsha kokulayisha.

Q5: Kungani ukhetha i-CDADA kunezinye izinhlobo ze-DC MCB?

A5: I-CDADA inikeza:

● Idizayini yokuphazamiseka kwe-arc yeqiniso ye-DC (ayishintshwanga nge-AC)

● Isitifiketi esigcwele se-IEC + CCC

● Sula inkomba yesimo sokubonwayo

● Ibanga lamanje elibanzi (1A–63A) lokulinganisa okunembile

● Amanani ancintisanayo anemibhalo yobuchwepheshe ngesiNgisi
