Yintoni eyenza i-MCCB kunye ne-MCB zifane?

I-Circuit breakers zizinto ezibalulekileyo kwiinkqubo zombane kuba zibonelela ngokhuseleko kwiisekethe ezimfutshane kunye neemeko ezidlulayo. Iindidi ezimbini eziqhelekileyo ze-circuit breakers zi-mold case circuit breakers (MCCB) kunye ne-miniature circuit breakers(MCB). Nangona ziyilelwe ubungakanani beesekethe ezahlukeneyo kunye nemisinga, zombini ii-MCCB kunye ne-MCBs zisebenza ngenjongo ebalulekileyo yokukhusela iinkqubo zombane. Kule bhlog, siza kuphonononga ukufana kunye nokubaluleka kwezi ntlobo zimbini zabaphuli beesekethe.

Ukufana okusebenzayo:

MCCB kunyeMCBZininzi izinto ezifanayo kumsebenzi ongundoqo. Basebenza njengokutshintsha, ukuphazamisa ukuhamba kombane xa kwenzeka impazamo yombane. Zombini iintlobo ze-breaker circuit zenzelwe ukukhusela iinkqubo zombane kwi-overloads kunye neesekethe ezimfutshane.

Ukhuseleko lwesekethe emfutshane:

Iisekethe ezimfutshane zibeka ingozi enkulu kwiinkqubo zombane. Oku kwenzeka xa uqhagamshelo olungalindelekanga lwenzeka phakathi kwabaqhubi ababini, nto leyo ebangela ukuqhambuka ngokukhawuleza kombane. Ii-MCCBs kunye nee-MCBs zixhotyiswe ngesixhobo sohambo esiva umsinga ogqithisileyo, saphula isekethe kwaye sinqanda nawuphi na umonakalo onokwenzeka okanye ingozi yomlilo.

Ukhuseleko lwangoku:

Kwiinkqubo zombane, iimeko ezigqithisileyo zinokuthi zenzeke ngenxa yokuchithwa kwamandla amaninzi okanye ukulayisha ngaphezulu. I-MCCB kunye ne-MCB zijongana ngokufanelekileyo neemeko ezinjalo ngokunqumla ngokuzenzekelayo isiphaluka. Oku kuthintela nawuphi na umonakalo kwisixhobo sombane kwaye kunceda ukugcina uzinzo lwenkqubo yamandla.

Amandla ombane kunye neereyithingi zangoku:

I-MCCB kunye ne-MCB ziyahluka ngobukhulu besiphaluka kunye nokulinganisa okusebenzayo ngoku. Ii-MCCBs ziqhele ukusetyenziswa kwiisekethe ezinkulu okanye iisekethe ezinemisinga ephezulu, ukusuka kwi-10 ukuya kumawaka e-amps. I-MCBs, ngakolunye uhlangothi, ifaneleke ngakumbi kwiisekethe ezincinci, zibonelela ngokhuseleko kuluhlu malunga ne-0.5 ukuya kwi-125 amps. Kubalulekile ukukhetha uhlobo olufanelekileyo lwe-breaker circuit esekelwe kwiimfuno zomthwalo wombane ukuqinisekisa ukukhuselwa okusebenzayo.

Indlela yohambo:

Zombini i-MCCB kunye ne-MCB zisebenzisa iindlela zokukhwelisa ukuphendula kwiimeko ezingaqhelekanga zangoku. Indlela yokukhubeka kwi-MCCB idla ngokuba yi-thermal-magnetic tripping mechanism edibanisa i-thermal kunye nemagnethi yokukhubeka. Oku kubenza bakwazi ukuphendula kwi-overload kunye neemeko zesekethe emfutshane. Ii-MCBs, kwelinye icala, zihlala zinesixhobo sokuhamba sobushushu esisabela ikakhulu kwiimeko zokugcwala. Eminye imifuziselo ye-MCB ephucukileyo ikwabandakanya izixhobo zokukhwela zombane zohambo oluchanekileyo nolukhethiweyo.

Ikhuselekile kwaye ithembekile:

I-MCCB kunye ne-MCB zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kweenkqubo zombane. Ngaphandle kwezi ziqhekezi zesekethe, umngcipheko womlilo wombane, umonakalo wezixhobo, kunye nokwenzakala okunokwenzeka kubantu ngabanye kwanda kakhulu. I-MCCBs kunye ne-MCBs zifaka isandla ekusebenzeni ngokukhuselekileyo kofakelo lombane ngokuvula ngokukhawuleza isiphaluka xa kufunyenwe impazamo.
