I-RDB8DC-63 DC MCB

I-RDB8DC-63 series DC miniature circuit breaker (lapha ibizwa ngokuthi i-circuit breaker), esetshenziswa kakhulu ku-DC operating voltage elinganisiwe ayidluli i-1000v, i-DC current elinganisiwe ayidluli i-63A, i-short circuit breaker elinganisiwe ayidluli umugqa wokusabalalisa wokuvikela we-10000A, njengoba umugqa ungaxhunywanga njalo, uphukile futhi uguqulwa. Ngokusebenzisa ngokweqile, umsebenzi wokuvikela i-short circuit.

Ngesikhathi esifanayo, inemodyuli enamandla yomsebenzi wokusiza, njengokuxhumana okusizayo, ukuxhumana nesibonakaliso se-alamu.

Imininingwane Yomkhiqizo

Isingeniso Somkhiqizo

I-RDB8DC series circuit breaker iwumkhiqizo we-circuit breaker onekhono eliphezulu lokukhawulela kanye nokuthembeka okuphezulu, owenzelwe ngokukhethekile imboni yezokuxhumana. Isetshenziswa kakhulu ezinhlelweni zokusabalalisa amandla ezifana namakhabethe amakhulu, amakhabethe kagesi, amakhabethe okusabalalisa, kanye namakhabethe angaphandle embonini yezokuxhumana.

Izimo Zokusebenza Ezijwayelekile Nezimo Zokufaka

● Umkhawulo ophezulu wokushisa komoya okuzungezile akumele udlule ku-+40℃, umkhawulo ophansi akumele ube ngaphansi kuka--5℃, kanti izinga lokushisa elimaphakathi lamahora angama-24 akumele lidlule ku-+35°C;

● Ukuphakama kwendawo yokufaka akufanele kudlule ama-2000m;

● Umswakama ohlobene womkhathi awudluli ku-50% uma izinga lokushisa lomoya elizungezile lingu-+40℃, kanti umswakama ohlobene ophezulu wehliswa ezingeni lokushisa eliphansi. Isibonelo, u-90% ku-+20℃. Kufanele kuthathwe izinyathelo ezikhethekile zokufinyela okwenzeka ngezikhathi ezithile kumkhiqizo ngenxa yokushintsha kwezinga lokushisa;

● Uma kuxhunywa izintambo, ipali efanele yomthombo wamandla kumele ixhunywe epalini elihle le-circuit breaker, kanti i-negative extreme kumele ixhunywe epalini elihle le-circuit breaker. Ukuxhumeka okuphambene akuvunyelwe;

● Izinga lokungcola: Izinga 2;

● Izimo zokufakwa: Kufakwe endaweni engenawo umthelela omkhulu, ukudlidliza, kanye nendawo engenangozi (ukuqhuma);

● Indlela yokufaka: Ukusebenzisa isitimela sokufaka se-TH35-7.5;

●Isigaba sokufaka: IsigabaⅡ, IsigabaⅢ.

Ukuhlukaniswa Komkhiqizo

☐ Ngokwenani lezinsika: 1P, 2P, 3P4P;

☐Ngokusho kwefomu lamanje elikhubeka ngokushesha: Uhlobo C (8ln±20%), Uhlobo D(12In±20%);

☐ Ngokusho komthamo wamanje olinganisiwe: 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A kanye no-63A;

☐Ngokusho kwe-voltage yokusebenza ekalwe: 125V/250V DC(1P), 250V/500V DC(2P), 300V/750V DC(3P), 500V/1000V DC(4P).

Idatha Eyinhloko Yobuchwepheshe

● Izici zokuhamba kwe-overcurrent Lapho i-circuit breaker ifakwa ngaphansi kwezimo ezijwayelekile kanye nokushisa okuzungezile (30-35℃), i-overcurrentizici zohambo zihambisana nezinhlinzeko zeThebula 1.

●Umthamo wokuphuka kwesekethe esifushane olinganisiwe we-circuit breaker uboniswe kuThebula 2.

Impilo kagesi yemishini:

I-circuit breaker ngaphansi kwe-voltage elinganisiwe ecacisiwe, vula bese uphula i-current elinganisiwe, i-power factor ingu-0.85 ~ 0.9, i-operating cyde izikhathi ezingu-120 ngehora (>32A) noma izikhathi ezingu-240 (≤32A) test frequency, impilo yayo yemishini kanye nekagesi izikhathi ezingu-10000, impilo kagesi DC izikhathi ezingu-1500.

Isakhiwo:

I-circuit breaker yakhiwe uhlelo lokuxhumana, uhlelo lokucisha i-arc, uhlelo lwe-electromagnetic, indlela yokukhubeka, indlela yokusebenza kanye nendlu.

Isimiso sokusebenza:

Ngaphansi kwezimo zokusebenza ezijwayelekile, donsa indlela yokusebenza, ngalesi sikhathi ukukhululwaIndlela yokusebenza ikhiyiwe, futhi oxhumana nabo abaguquguqukayo nabanganyakazi bayaxhumana ukuze kuxhunywe amandla.

Uma ulayini ugcwele ngokweqile, ishidi le-bimetal lesistimu ye-electromagnetic lidala ukuguqulwa, lisunduze ilokhi ukuze likhulule umshini, futhi lishukumise othintana naye ukuze anqamule futhi anqume ukunikezwa kwamandla. Uma isekethe inqanyuliwe, uhlelo lwe-electromagnetic ludonsa umongo wensimbi, bese induku ephezulu yomongo wensimbi isunduza ilokhi ukuze ikhulule umshini, kuqedwe umsebenzi wokuvikela ukuphuka kwe-circuit breaker.
