Ama-Miniature circuit breaker (ama-MCB)ziyizingxenye ezibalulekile ezinhlelweni zikagesi, ezisiza ekuvikeleni kuma-short circuits, overload kanye namaphutha. Kuyindlela ebalulekile yokuphepha yokuvimbela izingozi ezinkulu zamandla nokuqinisekisa ukusebenza kahle kwemishini kagesi.
Njengoba ubuchwepheshe buthuthuka kanye nesidingo sokusatshalaliswa kwamandla okuthembekile sikhula, ama-miniature circuit breaker abe yisinqumo esithandwayo kune-fuse yendabuko. Ngokungafani nama-fuse, adinga ukushintshwa ngemva kokuba eqhumile, ama-miniature circuit breaker angasethwa kabusha futhi asetshenziswe kabusha, okwenza abe ngcono kakhulu ngokuhamba kwesikhathi.
Enye yezinzuzo eziyinhloko ze-I-MCBusayizi wayo omncane. Njengoba igama lisho, lawa ma-breaker aklanyelwe ukungena ezindaweni eziqinile, okwenza afaneleke kakhulu ezindaweni zokuhlala, zezentengiselwano, kanye nezimboni. Usayizi wawo omncane awuthinti ukusebenza kwawo, njengoba i-MCB inikeza ukuvikelwa okusebenzayo kokulayisha ngokweqile kanye nokwe-short-circuit.
Esinye isici esihlukanisayo se-I-MCBisikhathi sayo sokuphendula ngokushesha. Uma kwenzeka iphutha noma ukunqwabelana ngokweqile,i-miniature circuit breakeribona ngokushesha ukungahambi kahle futhi iphazamiseke ngaphakathi kwama-millisecond. Le mpendulo esheshayo isiza ekuvimbeleni ukushisa ngokweqile kanye nemililo engaba khona, inciphise ingozi yezingozi zikagesi.
Ama-MCBzitholakala ngezilinganiso ezahlukene zamanje, okuvumela abasebenzisi ukuthi bakhethe i-circuit breaker efanele izidingo zabo zamandla ezithile. Lokhu kuguquguquka kwenza kube lula ukwenza izinhlelo zikagesi zivumelane nezidingo ezahlukene. Ngaphezu kwalokho, ama-MCB angafakwa kalula futhi ashintshwe ngaphandle kwemishini ekhethekile, okwenza kube ukukhetha okulula kosonkontileka bakagesi kanye nabaninikhaya ngokufanayo.
Ngaphezu kwemisebenzi yabo yokuvikela,Ama-MCBinganikeza ukuqonda okubalulekile mayelana nokuziphatha kwezinhlelo zikagesi. Ama-MCB amaningi afakwe izinkomba ezibonisa isimo se-I-circuit breaker, njengokuthi ngabe ikhubekile ngenxa yokugcwala ngokweqile noma iphutha. Lesi sici sisiza ukuxazulula izinkinga nokubona noma yiziphi izinkinga ezingaba khona ohlelweni lukagesi.
Ngokufigqiwe,ama-circuit breaker amancaneidlala indima ebalulekile ekuvikeleni izinhlelo zikagesi ngokuvimbela ukulayisha ngokweqile kanye namasekethe amafushane. Ubukhulu bayo obuncane, isikhathi sokuphendula ngokushesha kanye nokulula kokufakwa kwayo kwenza ifaneleke kakhulu ezinhlotsheni ezahlukene zezicelo. Ngokutshala imali ekhwalithini ephezuluAma-MCB, abantu ngabanye bangaqinisekisa ukusebenza okuphephile nokungaphazanyiswa kwezinhlelo zabo zikagesi.
