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-MCCB?

Ama-Molded case circuit breakers amadivayisi okuvikela kagesi aklanyelwe ukuvikela isekethe kagesi kusuka kumandla kagesi amaningi. Lo mandla kagesi amaningi angabangelwa ukugcwala ngokweqile noma isekethe esifushane. Ama-molded case circuit breakers angasetshenziswa ku-voltage ehlukahlukene kanye nama-frequency anomkhawulo ophansi nophezulu wezilungiselelo zokuhamba ezilungisekayo. Ngaphezu kwezindlela zokukhubeka, ama-MCCB angasetshenziswa futhi njengokushintshana kokuxhuma ngesandla uma kwenzeka isimo esiphuthumayo noma imisebenzi yokulungisa. Ama-MCCB ajwayelekile futhi ahlolwe ukugcwala kwamandla kagesi, ukukhuphuka kwamandla kagesi, kanye nokuvikelwa kwamaphutha ukuqinisekisa ukusebenza okuphephile kuzo zonke izindawo kanye nezinhlelo zokusebenza. Asebenza kahle njengokushintshana kabusha kwesekethe kagesi ukuze anqamule amandla futhi anciphise umonakalo obangelwa ukugcwala kwamandla kagesi, iphutha lomhlabathi, isekethe esifushane, noma lapho amandla kagesi edlula umkhawulo wamanje.

Isicelo se-MCCB

I-MCCB noma i-fuse iyisakhi sikagesi esivame ukusetshenziswa embonini ukuvikela imishini kagesi nezinhlelo. Empilweni yansuku zonke, i-MCCB isetshenziswa kabanzi. Ezinye izinhlelo zokusebenza ezivamile ze-MCCB zichazwe ngezansi.

1. Ukusatshalaliswa kwamandla: I-MCCB ingasiza abafaki ukusabalalisa imithwalo yegridi emishinini kagesi ehlukene. Nge-MCCB, abasebenzisi bangalawula ngokuphephile ukusatshalaliswa kwamandla kanye nogesi wedivayisi ngayinye.
2. Ukuvikelwa kwesekethe emfushane: Umsebenzi oyinhloko we-MCCB ukunqamula isekethe ngokuzenzakalelayo lapho kwenzeka isekethe emfushane. Lokhu kugwema ukulimala kwemishini, ukukhishwa kwezinto eziyingozi njengomlilo.
3. Ukuvikelwa kokulayisha ngokweqile: Njengokuvikelwa kwesekethe esifushane, i-MCCB ingavikela nemishini ekugcwalisweni ngokweqile. Lokhu kungafezwa ngokubeka ama-circuit breaker ukuze kugwenywe umonakalo kagesi obangelwa ukulayisha ngokweqile imishini.
4. Ukuvikelwa kwejeneretha: I-MCCB isetshenziswa kabanzi ekutholeni nasekuvikeleni amajeneretha amakhulu. Ingaqapha ukusebenza okuvamile kwejeneretha, ithole izinkinga futhi isebenze uhlelo lokuvikela i-circuit breaker.
5. Ukuvikelwa kwe-transformer yamandla: I-MCCB ingavimbela i-transformer ukuthi ingagcwali ngokweqile futhi iqaphe izinga lokushisa elingaphezu kwamandla e-transformer ngesikhathi esifanayo.
6. Ukuvikelwa kwesilinda esinyakazayo: I-MCCB isetshenziswa kabanzi kuma-crusher ekhonkrithi, esimendeni kanye namaminerali. Ibona ama-short circuits kanye nokugcwala ngokweqile kwemishini, ngaleyo ndlela ivikele imishini ekulimaleni.

Ekuphetheni, ama-MCCB asetshenziswa kabanzi futhi adlala indima ebalulekile emikhakheni eyahlukene kagesi neyemishini. Lapho ukhetha i-MCCB, izici ezahlukahlukene ezithile kudingeka zicatshangelwe ngokucophelela ukuze kuqinisekiswe ukuphepha nokuthembeka kohlelo, okuhlanganisa umthamo wamanje wokuthwala, ukusebenza kahle, indawo engasetshenziswa, kanye nezinye izilinganiso ezibalulekile.
