I-MOLDED CASE CIRCUIT BREAKERS (MCCB)

Ku-MCCB, umthamo wokuphulwa kwesekethe emfishane olinganiselwe ubhekisela kumthamo wokuphuka ngaphansi kwezimo ezithile.Ngemuva kwenqubo yokuhlola ecacisiwe, kuyadingeka ukucabangela ukuthi i-circuit breaker iyaqhubeka nokuthwala i-current yayo elinganiselwe.Ukuze kuhlangatshezwane nezidingo zabasebenzisi abahlukene, abakhiqizi abaningi be-circuit breaker manje bahlukanisa amandla okuphuka kwe-short-circuit yesilinganiso samanje segobolondo sibe ngamaleveli ahlukene, futhi abasebenzisi bangakhetha i-circuit breaker efanele ngokwezidingo zabo kusukela kokuncane kuya kokuphezulu. ama-circuit breakers amanje.Zivame kakhulu futhi zitholakala cishe kunoma yisiphi isakhiwo noma isakhiwo kangangokuthi ngokuvamile zithathwa kalula.Nokho, adlala indima ebalulekile ohlelweni lwethu lwegridi kagesi futhi kufanele agcinwe ukuze ahambisane nezindinganiso zakamuva zokuphepha.

 

Imodeli Yomkhiqizo

CJ:Ikhodi yebhizinisi
M: Isekhethi yekesi elibunjiwe
1:Nombolo yokuklama
□:Isilinganiso samanje sozimele
□:Ikhodi yesici somthamo wokwephulwa/S isho uhlobo olujwayelekile (S ingashiywa)H isho uhlobo oluphakeme

Qaphela: Kunezinhlobo ezine zesigxobo esimaphakathi (i-N pole) yomkhiqizo wezigaba ezine. Ipali emaphakathi yohlobo A ayifakelwe isici sokukhubeka samanje, ihlale ivuliwe, futhi ayivuswa noma ayicishwa kanye nezinye. izigxobo ezintathu.
Ipali engathathi hlangothi yohlobo B ayifakelwe into yokukhubeka yamanje, futhi iyavulwa noma icishwe kanye nezinye izigxobo ezintathu (i-pali ephakathi nendawo iyavulwa ngaphambi kokuba icishwe)Isigxobo esimaphakathi sohlobo C sifakwe ngaphezulu- into yamanje ekhubekayo, futhi iyavulwa noma icime kanye nezinye izigxobo ezintathu (i-pole engathathi hlangothi iyavulwa ngaphambi kokuba icishwe) Ipali engathathi hlangothi yohlobo D ifakwe isici sokukhubeka samanje, ihlale ivuliwe futhi ayishintshiwe. phezu noma vala kanye nezinye izigxobo ezintathu.
