Yintoni i-AC MCCB?

I-AC molded case circuit breaker (MCCB) yi-circuit breaker esetyenziselwa ukukhusela ii-electrical circuits kwi-overcurrent. Ngokungafaniyo nee-fuses zemveli, ekufuneka zitshintshwe emva kwempazamo, i-MCCB iphinda isetyenziswe emva kokukhubeka, nto leyo eyenza ibe sisisombululo sokukhusela ii-circuit esilula nesisebenzayo. "I-Molded case" ibhekisa kulwakhiwo lwesixhobo, ifaka izinto zangaphakathi kwi-casing yeplastiki eqinileyo, ibonelela ngokhuseleko kunye nokhuseleko kwiimeko zokusingqongileyo.

Iimpawu eziphambili zee-AC molded case circuit breakers

1. I-Rated Current: Ii-AC molded case circuit breakers (MCCBs) ziyafumaneka kwiindidi ezahlukeneyo zamanqanaba angoku, zihlala ziqala kwi-16 A ukuya kwi-2500 A. Oku kuguquguquka kuzenza zilungele uluhlu olubanzi lwezicelo, ukusuka kwiindawo zokuhlala ukuya kwiindawo zoshishino.

2. Useto Lohambo Oluhlengahlengiswayo: Ii-AC molded case circuit breakers ezininzi zinezicwangciso zohambo ezihlengahlengiswayo, ezivumela umsebenzisi ukuba alungelelanise umgangatho wokhuseleko kwiimfuno ezithile zenkqubo yombane. Olu phawu luluncedo ngakumbi kwizicelo apho iimeko zomthwalo zinokuhluka khona.

3. Ukhuseleko Lomthwalo Ogqithisileyo Nowesijikelezi Esifutshane: Ii-AC Molded Case Circuit Breakers (MCCBs) zenzelwe ukubona iimeko zomthwalo ogqithisileyo kunye neemeko zombane omfutshane. Kwimeko yomthwalo ogqithisileyo, i-MCCB iyahamba emva kokulibaziseka kwexesha elimiselweyo, okuvumela ukuba kubekho umsinga omfutshane wokungena. Kwimeko yombane omfutshane, i-MCCB iyahamba phantse ngoko nangoko ukuthintela umonakalo.

4. Iindlela zobushushu kunye neMagnetic: Ii-AC molded case circuit breakers zisebenza ngokuyintloko ngokusekelwe kwiindlela ezimbini: ubushushu kunye nemagnethi. Indlela yobushushu ikhusela ukugqithisa okude, ngelixa indlela yombane ikhusela ukuqhuma kombane ngequbuliso, inika ukhuseleko oluphindwe kabini.

5. Uyilo oluQhelekileyo: I-AC molded case circuit breaker (MCCB) inoyilo lwe-molded case olunesithuba esincinci, nto leyo eyenza ukuba ifaneleke kwiindawo zokufakela ezinesithuba esincinci. Olu yilo lukwaphucula ukuqina kwayo kunye nokuthembeka kwayo.

Ukusetyenziswa kwee-AC molded case circuit breakers

Ii-AC Molded Case Circuit Breakers (MCCBs) zisetyenziswa kakhulu kwiindawo ezahlukeneyo ngenxa yokuthembeka nokusebenza kwazo. Ezinye zezicelo eziqhelekileyo ziquka:

- Izakhiwo zeMizi-mveliso: Kwimizi-mveliso, ii-AC MCCB zikhusela oomatshini nezixhobo kwiingxaki zombane, ziqinisekisa ukusebenza okungaphazanyiswayo.

- Izakhiwo zorhwebo: Kwizakhiwo zeeofisi nakwiindawo zokuthenga ezinkulu, ezi zithinteli zesekethe zikhusela izibane kunye neenkqubo zokusasazwa kombane, ziphucula ukhuseleko lwabahlali.

- Ukufakelwa kwezindlu: Abanini bezindlu basebenzisa ii-AC MCCB kwiiphaneli zabo zombane ukukhusela iisekethe ezisebenzisa izixhobo zombane, iinkqubo ze-HVAC, kunye nezinye iinkonzo ezibalulekileyo.

- Iinkqubo zamandla ahlaziyekayo: Ngokunyuka kwamandla elanga nawomoya, ii-AC MCCBs zisetyenziswa ngakumbi ekufakweni kwamandla avuselelekayo ukukhusela ii-inverters kunye nezinye izinto kwiingxaki zombane.

Kufuphi

Ngamafutshane, ii-AC molded case circuit breakers (MCCBs) zizinto ezibalulekileyo kwiinkqubo zombane zanamhlanje, zibonelela ngokhuseleko oluthembekileyo lokugqithisela kunye nokhuseleko lwe-short-circuit. Useto lwazo oluhlengahlengiswayo, uyilo oluncinci, kunye neendlela zokukhusela ezimbini zizenza zilungele uluhlu olubanzi lwezicelo, ukusuka kwiindawo zokuhlala ukuya kwimizi-mveliso. Njengoko iinkqubo zombane ziqhubeka nokutshintsha, izixhobo ezifana nee-AC molded case circuit breakers ziya kuba zibaluleke ngakumbi, ziqinisekisa ukhuseleko kunye nokusebenza kakuhle kwenethiwekhi yokusasazwa kwamandla. Ukuqonda iimpawu zazo kunye nezicelo zazo kubalulekile kuye nabani na osebenza kubunjineli bombane okanye ulondolozo, njengoko kubanceda benze izigqibo zokhuseleko lwesekethe ezinolwazi.
