Ama-Miniature circuit breaker (ama-MCB)ziyingxenye ebalulekile yesistimu yakho kagesi, zivikela ikhaya lakho noma ibhizinisi lakho ezimotweni ezimfushane kanye nokugcwala ngokweqile. Zincane, kulula ukuzifaka futhi zinikeza ukuvikelwa kwamaphutha kagesi okusheshayo nokuthembekile.Ama-MCBzisetshenziswa kabanzi emakhaya, ezakhiweni zebhizinisi nasezindaweni zezimboni ukuvikela imililo kagesi nezinye izimo eziyingozi. Kule bhulogi, sizohlola ngokujulile ezinye zezici ezibalulekile zalokhuAma-MCB, ukuthi zisebenza kanjani, nokuthi kungani ziyingxenye ebaluleke kangaka yesistimu yakho kagesi.
Wenza njaniama-circuit breaker amancane ayasebenza?
I-MCB empeleni iyiswishi eshintsha ngokuzenzakalelayo uma ibona ugesi odlulayo noma ugesi omningi kakhulu esiketheni. Uma ugesi odlula kuyo udlula isilinganiso sayo, ibangela ukuthi izinto ezishisayo noma ezisebenza ngogesi ku-MCB ziphazamise ukugeleza kogesi. I-MCB yenzelwe ukushelela ngokushesha, ngokuvamile ngemizuzwana embalwa, lapho kutholakala ugesi omningi noma ugesi omfushane. Uma isiketheni sesishelele, iphazamisa ukugeleza kogesi esiketheni esinephutha futhi isiza ukuvimbela umonakalo emishinini kagesi kanye nemililo kagesi engaba khona.
Izakhiwo ezibalulekile zeI-MCB
Uma ukhethaI-MCB, kunezici eziningana ezibalulekile okufanele uzicabangele, okuhlanganisa uhlobo lwe-circuit breaker, isilinganiso samanje, umthamo wokuphazamiseka, kanye ne-trip curve. Uhlobo lwe-circuit breaker kufanele lufanele uhlelo lukagesi kanye nenani lamanje elithwalayo. Isilinganiso samanje sinquma ukuthi ingakanani i-currentI-MCBingakwazi ukusingatha ngaphambi kokukhubeka, kuyilapho amandla okuphuka kuyinani lamandla ephutha i-MCB engaliphula ngokuphephile. Ijika lohambo libalulekile njengoba linquma ukuthi i-MCB isabela ngokushesha kangakanani ekugcwalisweni ngokweqile noma kwisekethe emfushane futhi inamajika amathathu ayinhloko - ijika le-B lemithwalo ejwayelekile, ijika le-C lama-motor kanye nejika le-D lama-transformer anamandla.
Ukuvikelwa kokulayisha ngokweqile kanye nokujikeleza okufushane
Ukuvikela umthwalo ongaphezu komthwalo ngumsebenzi oyinhlokoI-MCBohlelweni lukagesi. Kuvikela imishini yakho kanye nezintambo ekushiseni ngokweqile ngenxa yamandla kagesi amaningi. Ukuvikelwa kwesekethe esifushane kungomunye umsebenzi obalulekile wama-miniature circuit breakers. Isekethe esifushane senzeka lapho kunendlela eqondile phakathi komthombo nomthwalo, okuholela ekugelezeni kwamandla kagesi ngokweqile kanye nengozi ephezulu yemililo kagesi. Kulesi simo esiyingozi, i-MCB iyakhubeka ngokushesha, ivimbele ukugeleza kwamandla kagesi okuqhubekayo futhi ivikele uhlelo ekulimaleni okungenzeka.
Ekuphetheni
Ekuphetheni,I-MCBkuyingxenye ebalulekile futhi ebalulekile yesistimu kagesi. Zivikela ikhaya lakho noma ibhizinisi lakho ekugcwaleni ngokweqile kanye nama-short circuits, zivikela imishini yakho futhi zigweme izimo ezingaba yingozi. I-MCB efanele kumele ikhethwe yesekethe yakho, kucatshangelwa izici ezifana nomthamo olinganiselwe, ukuphazamiseka kwamandla kanye ne-trip curve. Ukugcinwa njalo nokuhlolwa kwama-MCB akho kuzoqinisekisa ukuthi ayaqhubeka nokwenza imisebenzi yawo ebalulekile ngempumelelo, avikele uhlelo lwakho lukagesi futhi aqinisekise ukuphepha.
