    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

    IZIPHUTHULI ZESIFUNDA SESIKHATHI ESIBUMBWE (i-MCCB)

    Ku-MCCB, umthamo wokuphuka kwesekethe emfushane olinganiselwe ubhekisela kumthamo wokuphuka ngaphansi kwezimo ezibekiwe. Ngemva kwenqubo yokuhlola ebekiwe, kubalulekile ukucabangela ukuthi i-circuit breaker iyaqhubeka nokuthwala ugesi wayo olinganiselwe. Ukuze kuhlangatshezwane nezidingo zabasebenzisi abahlukene, abakhiqizi abaningi be-circuit breaker manje bahlukanisa umthamo wokuphuka kwesekethe emfushane wogesi ofanayo wesilinganiso segobolondo ube amazinga ahlukene, futhi abasebenzisi bangakhetha i-circuit breaker efanele ngokwezidingo zabo kusukela kokungenani kuya kokungenani okuphezulu kwe-circuit breaker. Zivame kakhulu futhi zitholakala cishe kunoma yisiphi isakhiwo noma isakhiwo kangangokuthi zivame ukuthathwa kalula. Noma kunjalo, zidlala indima ebalulekile ohlelweni lwethu lwegridi kagesi futhi kufanele zigcinwe ukuze zihambisane nezindinganiso zokuphepha zakamuva.

    Ama-MCCB anikeza impendulo esheshayo ku-full circuit fault current, ngokusekelwe esimisweni se-electromagnetism. I-MCCB iqukethe i-solenoid coil ekhiqiza insimu encane ye-electromagnetic lapho i-current idlula kwi-MCCB. I-MCCB isebenzisa idivayisi ezwela izinga lokushisa (i-thermal element) enedivayisi ye-electromagnetic ezwela izinga lokushisa (i-magnetic ezwela izinga lokushisa) ukuze inikeze indlela yokuhamba (i-thermal magnetic) ngezinjongo zokuvikela ukushisa kanye nokuhlukanisa. Ngesikhathi sokusebenza okuvamile noma izimo ezijwayelekile, insimu ye-electromagnetic ekhiqizwa yi-solenoid coil ayinakwa. Kodwa-ke, lapho kwenzeka iphutha le-full circuit ku-circuit, i-full current enkulu iqala ukugeleza nge-solenoid futhi, ngenxa yalokho, kusungulwa insimu enamandla ye-electromagnetic edonsela ibha yokuhamba futhi ivule oxhumana nabo.
