Kusiyana pakati pa MCB ndi MCCB

Pali mitundu iwiri yodziwika bwino ya ma circuit breaker omwe amagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana:zophulitsira ma circuit breakers opangidwa ndi chipolopolo (MCCBndizodulira zazing'ono za dera (MCBZonsezi ndi zinthu zofunika kwambiri mu makina amagetsi, zomwe zimateteza ku zinthu zambirimbiri komanso ma circuit afupi. Komabe, pali kusiyana kwakukulu pakati pa mitundu iwiriyi ya ma circuit breaker, ndipo kumvetsetsa kusiyana kumeneku ndikofunikira posankha chinthu choyenera kugwiritsa ntchito.

Ntchito yaikulu ya MCCB ndikupereka chitetezo cha overload ndi short-circuit m'makina ogawa magetsi otsika komanso ma motor protection circuits. Amadziwika kuti ndi odalirika komanso okhazikika, zomwe zimapangitsa kuti akhale otchuka kwambiri m'mafakitale. Koma ma miniature circuit breaker amagwiritsidwa ntchito poteteza ma terminal distributor units m'nyumba. Ngakhale kuti ndi ma circuit breaker, pali kusiyana pakati pa ma MCCB ndi ma MCB komwe kuyenera kuganiziridwa posankha chinthu choyenera kugwiritsa ntchito.

Choyamba, ma circuit breaker opangidwa ndi utomoni ndi ma miniature circuit breaker onse ayenera kutsatira miyezo yoyambira ya malonda ndipo ali ndi mfundo yogwirira ntchito yofanana ndi ma circuit breaker. Koma pali kusiyana koonekeratu pakati pa awiriwa pankhani ya magetsi ndi makina komanso malo oyenera ogwirira ntchito.

Kusiyana kwakukulu pakati pa MCCB ndi MCB ndi momwe magetsi amagwiritsidwira ntchito. MCCB imafika pa 2000A, zomwe zimapangitsa kuti ikhale yoyenera zipinda zazikulu komanso katundu wolemera wamagetsi. Komano, ma MCB ali ndi mphamvu yamagetsi ya 125A, zomwe zimachepetsa mphamvu zawo ndikuzipangitsa kukhala zoyenera kugwiritsidwa ntchito m'malo ang'onoang'ono. Kusiyana kumeneku kwa mphamvu yamagetsi kumatanthauza kuti ma MCCB ndi oyenera kwambiri m'malo amakampani ndi amalonda komwe katundu wamagetsi waukulu ndi wofala, pomwe ma MCB nthawi zambiri amagwiritsidwa ntchito m'malo okhala ndi ang'onoang'ono amalonda.

Kuwonjezera pa magawo amagetsi, palinso kusiyana kwa magawo amakina pakati pa MCCB ndi MCCB. Mwachitsanzo, mawaya olumikizidwa ku MCCB nthawi zambiri amakhala okhuthala, ndipo malo opitilira 35 sikweya mita. Mosiyana ndi zimenezi, MCB idapangidwa kuti igwiritse ntchito mawaya ang'onoang'ono ndipo ndi yoyenera madera okwana 10 sikweya mita. Kusiyana kumeneku kwa makina kumatanthauza kuti MCCB ndi yoyenera kugwiritsa ntchito makina akuluakulu amagetsi, pomwe MCB ndi yoyenera kugwiritsa ntchito pang'ono.

Chinthu china chofunikira kuganizira ndi malo ogwirira ntchito. Ma MCCB amapangidwira kuti azigwiritsidwa ntchito m'malo osiyanasiyana, kuphatikizapo mafakitale ndi mabizinesi. Amatha kunyamula katundu wolemera wamagetsi ndipo ndi olimba kwambiri, zomwe zimapangitsa kuti azigwiritsidwa ntchito pomwe kudalirika ndikofunikira. Koma ma MCB amapangidwira kuti azigwiritsidwa ntchito pomanga makina ogawa magetsi ndipo ndi oyenera kwambiri m'malo okhala ndi ang'onoang'ono amalonda.

Mwachidule, ngakhale kuti MCCB ndi MCB zonse ndi zinthu zofunika kwambiri mu makina amagetsi, zimapangidwa kuti zigwiritsidwe ntchito mosiyanasiyana ndipo zimakhala ndi kusiyana kwakukulu mu magawo awo amagetsi ndi makina. Kumvetsetsa kusiyana kumeneku ndikofunikira kwambiri posankha chinthu choyenera kwambiri pa ntchito inayake, kaya ndi malo amakampani, amalonda kapena okhalamo. Poganizira zinthu monga momwe zilili panopa, magawo a makina ndi malo ogwirira ntchito, chisankho chodziwikiratu chingapangidwe posankha MCCB ndi MCB za makina enaake amagetsi.
