Ama-Cjm1 Electrical Electronic Adjustable Mold Case Circuit Breakers MCCB

Incazelo emfushane:

I-molded case circuit breaker iyisivikelo sensimbi esibamba isethi yoxhumana nabo abahambayo ngaphakathi. I-metal case inikeza ukuvikelwa kokusebenzisa ugesi ngokweqile futhi ingamunca ukukhuphuka kwamandla kagesi ngokweqile kuyilapho oxhumana nabo bevuleka ngokuzenzakalelayo ukuze kuncishiswe ukugcwala kwamandla kagesi ngokuphephile. Ama-MCCB eza ngezilinganiso ezahlukene, ngakho-ke kubalulekile ukukhetha uhlobo olufanele ngokuya ngesilinganiso samandla kagesi sephaneli yokulawula, umthamo we-short-circuit, izidingo zokushisa, kanye ne-voltage yesistimu kagesi. Futhi anezilinganiso zokuphazamiseka okuphezulu kune-miniature circuit breakers ukuze akhonze izinhlelo zokusebenza zezimboni nezentengiselwano ezinamandla aphezulu, njengamaphaneli okulawula, i-OEM, kanye nemishini yokusabalalisa kagesi.

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.

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.
