I-JCM1- Ikesi Elibunjiwe Lesekhethi

JCM1 uchungechunge MoldedI-Case Circuit Breaker (kamuva ebizwa ngokuthi i-circuit breaker) iwuhlobo olusha lwe-circuit breaker oluthuthukiswe inkampani yethu ngomklamo othuthukile wamazwe ngamazwe nobuchwepheshe bokukhiqiza.

Ukuvikelwa kokulayisha ngokweqile, Ukuvikelwa kwesekethe emfishane, Ukuvikelwa ngaphansi kwamandla kagesi

I-voltage yokufaka elinganiselwe efika ku-1000V, ilungele ukuguqulwa okungajwayelekile kanye nokuqaliswa kwemoto

I-voltage yokusebenza elinganiselwe ifike ku-690V,

Itholakala ku-125A, 160A, 200A, 250A, 300A, 400A, 600A, 800A

Ihambisana ne-IEC60947-2

Isingeniso:

Ama-Molded Case Circuit Breakers (MCCB) ayingxenye edingekayo yamasistimu kagesi, ahlinzeka ngokuvikeleka kokugcwala ngokweqile kanye nokuvikela isekethe emfishane.Ezimweni eziningi, ama-MCCB afakwa ebhodini elikhulu lokusabalalisa amandla esikhungweni, okuvumela isistimu ukuthi ivalwe kalula uma kunesidingo.Ama-MCCB atholakala ngamasayizi ahlukahlukene kanye nezilinganiso, kuye ngosayizi wesistimu kagesi.

Kulo mhlahlandlela, sizofaka izingxenye nezici ze-MCCB ejwayelekile, ukuthi zisebenza kanjani, nokuthi yiziphi izinhlobo ezitholakalayo.Sizophinde sixoxe ngezinzuzo zokusebenzisa lolu hlobo lwe-breaker ohlelweni lwakho lukagesi.

I-lts rated insulation voltage voltage ingu-1000V, elungele ukuguqulwa okungajwayelekile kanye nemoto eqala kumasekhethi ane-AC 50 Hz, ikalwe i-voltage yokusebenza yafika ku-690V futhi ikalwe njengamanje yafika ku-800ACSDM1-800 ngaphandle kokuvikelwa kwemoto).

Izinga: I-IEC60947-1, igeneral

I-lEC60947-2low voltage circuit breaker

IEC60947-4 electromechanical circuit breakers kanye neziqalisi zezimoto

I-IEC60947-5-1, i-electromechanical control circuit apparatus

Izici ezibaluleke kakhulu

● I-circuit breaker inomthwalo omningi, isifunda esifushane kanye nemisebenzi yokuvikela i-undervoltage, engavikela ulayini kanye nezinto zokusebenza zamandla ekulimaleni.Ngesikhathi esifanayo, inganikeza ukuvikeleka kokuxhumana okungaqondile kubantu, futhi inganikeza nokuvikelwa kwephutha lesikhathi eside lesisekelo elingenakutholwa ukuvikela okungaphezu kwamanje, okungase kubangele ingozi yomlilo.
● I-circuit breaker inezici zevolumu encane, ukuphakama okuphezulu kokuphuka, i-arcing emfushane kanye ne-anti vibration
● I-circuit breaker ingafakwa ngokuqondile nangokuvundlile
● I-circuit breaker ayikwazi ukushintshwa, okungukuthi, u-1, 3 no-5 kuphela ovunyelwe njengamatheminali kagesi, futhi u-2, 4 no-6 amatheminali okulayisha
● I-circuit breaker ingahlukaniswa ngezintambo zangaphambili, izintambo ezingemuva kanye ne-plug-in wiring

Idatha Yezobuchwepheshe

Iyini i-MCCB?

I-MCCB iyifomu elifushane le-Molded Case Circuit Breaker.Kuyisibonelo esivamile sedivayisi yokuphepha kagesi evame ukusetshenziswa kakhulu uma umthamo wamanje uphakeme kakhulu kunomkhawulo we-breaker circuit encane.

I-MCCB inikeza isivikelo kumaphutha wesekethe emifushane futhi isetshenziselwa ukushintsha amasekhethi.Ingasetshenziselwa izilinganiso eziphezulu zamanje kanye nezinga lephutha, esimweni sezinjongo ezimbalwa zasekhaya.Izilinganiso zamanje ezibanzi namandla okuphuka okuphezulu ku-Molded Case Circuit Breaker kusho ukuthi zifaneleka ngisho nezizathu zemboni.

Isebenza kanjani i-MCCB?

I-MCCB isebenzisa idivayisi ezwelayo kukushisa (into eshisayo) enedivayisi yamanje ebucayi kazibuthe (into kazibuthe) ukuze inikeze indlela yohambo ngezinjongo zokuvikela nokuzihlukanisa.Lokhu kwenza i-MCCB ikwazi ukuhlinzeka:

Ukuvikelwa kokulayisha ngokweqile,

Ukuvikelwa Kwephutha Logesi ngokumelene nemisinga emifushane yesekethe, kanye

Iswishi kagesi yokunqanyulwa.

Uyini umehluko phakathi kwe-MCB ne-MCCB?

I-MCB ne-MCCB ngamadivayisi asetshenziswa kakhulu okuvikela isekethe.Lawa madivaysi ahlinzeka ngokuvikeleka kumasekhethi amanje namafushane.Kunomehluko omncane phakathi kwalawa madivayisi womabili ngaphandle komthamo olinganiselwe wamanje.Umthamo wamanje olinganiselwe we-MCB uvamise ukuba ngaphansi kuka-125A, futhi i-MCCB iyatholakala kuze kufike esilinganisweni esingu-2500A.
