Umahluko phakathi kwe-MCB kunye ne-MCCB

Xa kufikwa kwi-circuit breakers, iindlela ezimbini ezisetyenziswa kakhulu yi-MCB kunye ne-MCCB. Nangona zombini zisetyenziselwa ukukhusela iinkqubo zombane kwi-overloads kunye ne-short circuits, kukho umahluko omkhulu phakathi kwezi mveliso zimbini.

Isixhobo sokwaphula iisekethe esincinci (I-MCB), njengoko igama lisitsho, sisixhobo sokuqhekeza iisekethe esincinci esinemisebenzi emininzi. Sisetyenziswa kakhulu kwiindawo ezahlukeneyo ezifana nemizi-mveliso, urhwebo, izakhiwo eziphakamileyo, kunye neendawo zokuhlala. Ii-MCB zenzelwe ukubonelela ngokhuseleko kwiiyunithi zokusasazwa kwee-terminal zombane kwizakhiwo. Kukho iintlobo ezininzi kunye nobuninzi beemveliso ze-circuit breaker, ezifanelekileyo kwizicelo ezahlukeneyo.

Enye yezona nzuzo ziphambili ze-MCB kukukwazi kwayo ukusingatha uluhlu olubanzi lweeparamitha zombane. Ifanelekile ukhuseleko olugqithisileyo nolwe-short-circuit kwimigca ene-AC 50/60Hz rated voltage 230/400V kunye ne-current rated ukuya kuthi ga kwi-63A. Ukongeza, ii-circuit breakers ezincinci zingasetyenziselwa nokutshintsha imigca rhoqo phantsi kweemeko eziqhelekileyo. Oku kuguquguquka kwenza ukuba zilungele iinkqubo ezininzi zombane.

Kwelinye icala,abaphuli beesekethe zetyala elibunjiweyo (I-MCCB) zisetyenziswa kakhulu kwiinkqubo zokusasazwa kwamandla aphantsi kunye neesekethe zokukhusela iimoto. Ibonelela ngokhuseleko lokugqithisa kunye nolwesekethe emfutshane. Uphawu oluphambili oluphawulekayo lwe-MCCB yibhokisi yayo yeplastiki, esebenza njengesigqubuthelo kwaye ihlukanisa ii-conductors kunye neendawo zesinyithi ezisekelwe phantsi. Ngenxa yokuthembeka kwayo nokuzinza, ii-molded case circuit breakers zisetyenziswe kakhulu kumashishini ahlukeneyo.

Nangona zombini i-MCB kunye ne-MCCB zizixhobo zokuqhekeza iisekethe, kukho umahluko omkhulu phakathi kwazo. Okokuqala, zinemilinganiselo eyahlukeneyo yombane kunye neye-mechanical. I-MCB ifanelekile kwiingcingo ezifikelela kwi-10 square metres, ngelixa i-MCCB inokudibanisa iingcingo ezityebileyo, ezifana neengcingo ezingaphezulu kwe-35 square metres. Oku kwenza i-MCCB ikwazi ukusingatha amandla aphezulu kunye nemisinga.

Omnye umahluko yindlela eziqhagamshelwe ngayo. Iiterminal ze-molded case circuit breaker ziqhagamshelwe neenati, ezinokucinezelwa lula kwaye ziqinisekise uqhagamshelwano oluhle. Ngokwahlukileyo koko, ii-MCB zisebenzisa iiterminal ezincinci zoxinzelelo ezinokuqiniswa kuphela nge-screwdriver. Olu mahluko kwiindlela zoqhagamshelo luchaphazela uxinizelelo kunye nomgangatho woqhagamshelwano.

Ngaphezu koko, i-MCB kunye ne-MCCB zineendawo zokusebenza ezahlukeneyo. Ii-MCB zenzelwe iintlobo ngeentlobo zezicelo, nto leyo ezenza zifaneleke ukusetyenziswa kwiindawo ezahlukeneyo. Kwelinye icala, i-MCCB isetyenziswa kakhulu kwizicelo zokutshintsha ubungakanani bombane obuncinci.

Ngamafutshane, nangona ii-miniature circuit breakers kunye nee-molded case circuit breakers zombini zisetyenziselwa ukukhusela iinkqubo zombane, zineempawu ezithile ezahlukeneyo. I-MCB isetyenziswa kakhulu kwaye ineendlela ezahlukeneyo zokusetyenziswa, ngelixa i-MCCB isetyenziswa kakhulu kwiinkqubo zokusasazwa kwamandla aphantsi kunye neesekethe zokukhusela iimoto. Zahlukile kwiiparameter zombane kunye nezoomatshini, iindlela zonxibelelwano kunye nendawo yokusebenza. Ukuqonda ezi mahluko kuya kunceda ekumiseleni ukuba yeyiphi i-circuit breaker efanelekileyo kwiimfuno zakho ezithile.
