Ama-circuit breaker amancane, ngokuvamile kubizwa ngokuthiAma-MCB, ziyingxenye ebalulekile yezinhlelo zikagesi zesimanje. Kuyithuluzi lokuphepha elibalulekile elivikela amasekethe ekugcwaleni ngokweqile kanye namasekethe amafushane, livimbele umonakalo kumishini kanye nohlelo lonke. Lesi sihloko sizoxoxa ngokubaluleka kanye nendima yalokhuama-circuit breaker amancane.
Omunye wemisebenzi eyinhloko ye-I-MCBukuqapha ugesi ogeleza ngesekethe bese uwuphazamisa uma kwenzeka into engavamile. Uvula isekethe ngokuzenzakalelayo, uphazamise ukuhamba kukagesi, ngaleyo ndlela uvimbele noma yimuphi umonakalo ongaba khona. Lesi sici sibaluleke kakhulu ukuvimbela izingozi zomlilo ezibangelwa ukushisa ngokweqile noma amaphutha kagesi.
Ama-circuit breaker amancanezenzelwe ukuphatha amazinga ahlukene kagesi. Zitholakala ngamamaki ahlukahlukene, okuvumela abasebenzisi ukuthi bakhethe okufaneleI-MCBngokwezidingo zabo ezithile. Lezi zilinganiso zivame ukuvezwa ngama-ampere (A) futhi zimele ugesi ophezulu ongadlula ku-circuit breaker ngaphandle kokukhubeka.
Indlela yokusebenza yei-miniature circuit breakerkufaka phakathi i-electromagnet kanye nengxenye ye-bimetallic. Uma kwenzeka ukugcwala ngokweqile noma i-short circuit, ugesi odlula ku-I-MCBidlula umkhawulo wayo olinganiselwe ophezulu. Lokhu kubangela ukuthi i-bimetal igobe ngenxa yokushisa okwandisiwe, ekugcineni kukhubeke isekethe. Uma kwenzeka ukugcwala ngokweqile noma isekethe esifushane, i-electromagnet ivala ngokushesha, inikeze isivikelo esisheshayo nesithembekile.
Ama-circuit breaker amancaneinikeza izinzuzo eziningana ngaphezu kwama-fuse avamile. Angasethwa kabusha kalula ngemva kokukhubeka, okususa isidingo sokushintsha isikhathi ngasinye lapho kuvela iphutha. Ukukwazi ukusetha kabusha i-circuit breaker akugcini nje ngokusindisa isikhathi kodwa futhi kunciphisa nezindleko zokulungisa. Ngaphezu kwalokho,Ama-MCBukunikeza isivikelo esinembile nesinembile ngokuthola nokuphendula ekushintsheni okuncane kwamandla kagesi ngesikhathi esifanele.
Ngokufigqiwe,ama-circuit breaker amancaneziyingxenye ebalulekile yezinhlelo zikagesi njengoba zihlinzeka ngokuvikelwa okusebenzayo kokulayisha ngokweqile kanye nokwe-short-circuit. Amandla azo okuphula isekethe ngokushesha asiza ukuvimbela izingozi zikagesi nokuqinisekisa ukuphepha kwabantu nemishini. Ngokukhetha isilinganiso esifanele, abasebenzisi bangenza ngokwezifiso izinga lokuvikelwa elidingekayo ekusethweni kwabo kukagesi okuthile. Sekukonke, ukutshala imali kwikhwalithii-miniature circuit breakerkubalulekile ekugcineni ukuphepha nokuthembeka kwanoma yiluphi uhlelo lukagesi.
