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)

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.

Imodeli Yomkhiqizo

I-CJ: Ikhodi yebhizinisi
M: Isiphuli sesekethe sekesi esibunjiwe
1: Inombolo Yomklamo
□:Uhlaka lwamanje olulinganiselwe
□:Ikhodi yesici/S echaza umthamo wokwephuka imelela uhlobo olujwayelekile (u-S angashiywa) u-H umelela uhlobo oluphezulu

Qaphela: Kunezinhlobo ezine ze-neutral pole (i-N pole) zomkhiqizo wezigaba ezine. I-neutral pole yohlobo A ayinayo i-extra-current tripping element, ihlala ivuliwe, futhi ayivulwa noma ivalwe kanye nezinye izigxobo ezintathu.
I-neutral pole yohlobo B ayinayo i-over-current tripping element, futhi ivuliwe noma ivaliwe kanye nezinye izinti ezintathu (i-neutral pole iyavulwa ngaphambi kokuba icishwe) I-neutral pole yohlobo C ine-over-current tripping element, futhi ivuliwe noma icishwe kanye nezinye izinti ezintathu (i-neutral pole iyavulwa ngaphambi kokuba icishwe) I-neutral pole yohlobo D ine-over-current tripping element, ihlala ivuliwe futhi ayivulwa noma icishwe kanye nezinye izinti ezintathu.

Isimo Sesevisi Esijwayelekile

Ukuphakama kwendawo yokufaka akumele kudlule ama-2000m
Izinga lokushisa lomoya elizungezile
Izinga lokushisa lomoya elizungezile akufanele lidlule +40℃
Inani elimaphakathi akufanele lidlule +35℃ emahoreni angama-24
Izinga lokushisa lomoya elizungezile akufanele libe ngaphansi kuka -5℃
Isimo somkhathi:
1 Kukhona umswakama womoya oshisayo lapha akumele udlule ku-50% ekushiseni okuphezulu okungu-+40℃, futhi kungaba ngaphezulu kwezinga lokushisa eliphansi, lapho izinga lokushisa eliphansi kakhulu enyangeni enemvula kakhulu lingadluli ku-25℃ lingaba ngu-90%, ukuncishiswa komswakama ebusweni bomkhiqizo ngenxa yokushintsha kwezinga lokushisa kumele kucatshangelwe.
Izinga lokungcola liyisigaba sesi-3
