    Isicelo

    I-CJMM1 series molded case circuit breaker (ebizwa ngokuthi i-circuit breaker) iyasebenza kwi-AC 50/60HZ power distribution network circuit ene-insulation voltage elinganisiwe engu-800V, i-operation voltage elinganisiwe engu-690V kanye ne-operation current elinganisiwe kusukela ku-10A kuya ku-630A, isetshenziselwa ukusabalalisa amandla nokuvimbela imishini yesekethe kanye neyokuphakelwa kwamandla ekulimaleni ngenxa yokugcwala ngokweqile, i-short circuit, i-under voltage kanye nezinye izinkinga, isetshenziselwa futhi ukuqala kaningi kwemoto kanye nokugcwala ngokweqile, i-short circuit kanye nokuvikelwa kwe-voltage. Le circuit breaker inezinzuzo zevolumu encane, amandla aphezulu okuphuka, i-short arcing (noma i-noarcing) njll., ingafakelwa izesekeli ezifana nokuxhumana kwe-alamu, ukukhululwa kwe-shunt, ukuxhumana okusizayo njll., ingumkhiqizo ofanele umsebenzisi. I-residual current current breaker ingafakwa ngokuqondile (ukufakwa okuqondile) noma ifakwe ngokuvundlile (ukufakwa okuvundlile). Umkhiqizo uhambisana namazinga e-IEC60947-2 kanye ne-Gb140482

    Kuyini i-DC MCCB?

    Ukuqonda i-DC MCCB: Umhlahlandlela Ophelele

    Emkhakheni wobunjiniyela kagesi kanye nokusatshalaliswa kwamandla, igama elithi “MCCB” livela kaningi. I-MCCB imele i-Molded CaseI-circuit breakerfuthi iyisici esibalulekile ekuvikeleni amasekethe kusuka ku-overcurrent, amasekethe amafushane kanye nezinye izinkinga zikagesi. Nakuba ama-AC MCCB exoxwa kabanzi, ama-DC MCCB nawo abaluleke ngokulinganayo, ikakhulukazi ezinhlelweni ezihilela izinhlelo zamandla aqondile (DC). Le bhulogi ihlose ukucacisa ama-DC molded case circuit breakers futhi ixoxe ngemisebenzi yawo, izinhlelo zokusebenza kanye nezinzuzo.

    Iyini i-DC molded case circuit breaker?

    I-DC Molded Case Circuit Breaker (DC MCCB) noma i-DC Molded Case Circuit Breaker iyi-circuit breaker eyenzelwe ngokukhethekile ukuvikela amasekethe e-DC. Ngokungafani nama-AC ahambisana nawo, ama-DC MCCB aklanyelwe ukubhekana nezinselele ezihlukile ezilethwa yi-DC, njengokuntuleka kwendawo yokuwela ugesi kanye nethuba lokuhamba njalo. Lawa ma-circuit breaker abalulekile ezimbonini ezahlukahlukene, okuhlanganisa amandla avuselelekayo, ezokuthutha kanye nezokuxhumana, ezivame ukusebenzisa izinhlelo zamandla ze-DC.

    Isebenza kanjani i-DC molded case circuit breaker?

    Umsebenzi oyinhloko we-DC molded case circuit breaker ukuphazamisa ugesi uma kwenzeka ukulayisha ngokweqile noma ugesi omfushane. Nasi isixazululo sesinyathelo ngesinyathelo sendlela osebenza ngayo:

    1. Ukutholwa: I-DC molded case circuit breaker iqapha njalo ugesi ogeleza kugesi. Uma ugesi udlula umthamo olinganiselwe we-circuit breaker, indlela yokuvikela iyaqala ukusebenza.

    2. Ukuphazamiseka: Uma kutholakala ukuthi i-overcurrent iyasebenza, i-circuit breaker ivula oxhumana nabo ukuze iphazamise ukugeleza kwamanje. Lesi senzo sivimbela umonakalo ku-circuit kanye nemishini exhunyiwe.

    3. Ukucisha i-Arc: Enye yezinselele ezinkulu ezinhlelweni ze-DC ukwakheka kwama-arcs. Lapho oxhumana nabo bevuleka, kwakheka i-arc ngenxa yokuqhubeka komsinga we-DC. Ama-DC molded case circuit breakers afakwe izindlela zokucisha i-arc, njengezindawo zokucisha i-arc noma amadivayisi okucisha i-arc asebenzisa i-magnetic blow, ukuze asuse ama-arcs ngokuphephile.

    4. Setha kabusha: Ngemva kokuthi iphutha selisusiwe, i-circuit breaker ingasethwa kabusha ngesandla noma ngokuzenzakalelayo ukuze kuqalwe kabusha ukusebenza okuvamile.

    Izici eziyinhloko ze-DC molded case circuit breaker

    Ama-circuit breaker e-DC molded case anezici eziningana ezenza afaneleke kuzinhlelo zokusebenza ze-DC:

    - Amandla Okuphula Amandla: Zenzelwe ukusingatha imisinga yamaphutha aphezulu, ziqinisekisa ukuvikelwa okuthembekile ngisho nasezindaweni ezinzima.
    - Amayunithi Ohambo Olushisayo Nolune-Magnetic: Lawa mayunithi ahlinzeka ngokuvikelwa okubili ngokuphendula ku-overcurrent ende (eshisayo) kanye ne-short circuit yesikhashana (ene-magnetic).
    - Izilungiselelo Zohambo Ezilungisekayo: Ama-DC MCCB amaningi anikeza izilungiselelo zohambo ezilungisekayo, okuvumela ukwenza ngezifiso izidingo ezithile zohlelo lokusebenza.
    - Umklamo Omncane: Umklamo wendlu ebunjiwe uqinisekisa isimo esiqinile nesiqinile, okwenza kube lula ukuhlanganiswa nezinhlelo ezahlukahlukene.

    Ukusetshenziswa kwe-DC Molded Case Circuit Breaker

    Ama-circuit breaker e-DC abunjwe nge-DC asetshenziswa kabanzi ezimbonini nasezimweni ezahlukahlukene:

    - Amandla Avuselelekayo: Izinhlelo zamandla elanga, ama-wind turbine kanye nezinhlelo zokugcina amandla zivame ukusebenzisa ama-DC molded case circuit breakers ukuvikela izifunda zazo.
    - Izimoto Zikagesi (i-EV): Ama-DC molded case circuit breakers asetshenziswa eziteshini zokushaja izimoto zikagesi kanye nasezinhlelweni ezisebhodini ukuqinisekisa ukusebenza okuphephile.
    - Ezokuxhumana: Ingqalasizinda yezokuxhumana ethembele kakhulu kumandla e-DC isebenzisa lawa ma-circuit breaker ukuvikela imishini ebalulekile.
    - Ukuzenzakalela Kwezimboni: Ama-DC Molded Case Circuit Breakers asetshenziswa ezinqubweni ezahlukene zezimboni kusetshenziswa ama-motor nama-drive e-DC.

    Izinzuzo zokusebenzisa ama-DC molded case circuit breakers

    - Ukuphepha Okuthuthukisiwe: Ama-circuit breaker e-DC abunjwe nge-DC athuthukisa ukuphepha kwezinhlelo zikagesi kanye nabasebenzi ngokunikeza ukuvikelwa okuthembekile kwe-overcurrent kanye ne-short circuit.
    - ISIKHATHI SOKUPHUTHA ESINCIPHISIWE: Ukuphazamiseka okusheshayo kokwehluleka kunciphisa umonakalo futhi kunciphisa isikhathi sokungasebenzi, okuqinisekisa ukusebenza okuqhubekayo kwezinhlelo ezibalulekile.
    - Okungabizi: Kuvimbela umonakalo emishinini ebizayo futhi kunciphise izindleko zokulungisa, okwenza ama-DC Molded Case Circuit Breakers abe yisisombululo esingabizi kakhulu.

    Ngokufigqiwe

    I-DC molded case circuit breaker iyisici esibalulekile ezinhlelweni zikagesi zesimanje, enikeza isivikelo esiqinile futhi iqinisekisa ukusebenza okuphephile kwamasekethe e-DC. Ukuqonda imisebenzi yayo, izici, kanye nezinhlelo zokusebenza kungasiza onjiniyela kanye nochwepheshe ukuthi benze izinqumo ezinolwazi lapho beklama futhi begcina izinhlelo zikagesi ze-DC. Njengoba isidingo samandla avuselelekayo kanye nezimoto zikagesi siqhubeka nokukhula, ukubaluleka kwama-DC molded case circuit breakers kuzokhula kuphela, okwenza kube yingxenye ebalulekile yengqalasizinda yethu yamandla.
