Ugesi ungumthombo wamandla obalulekile emisebenzini yethu yansuku zonke. Kodwa-ke, ngaphezu kwezinzuzo zawo, ungadala nezingozi ezinkulu uma ungaphathwa kahle. Yingakho ukuba nama-circuit breaker athembekile kubalulekile ekugcineni izinhlelo zethu zikagesi ziphephile. I-miniature circuit breaker (I-MCB) ingenye yalezi zixhobo ezisetshenziswa kakhulu kwezobunjiniyela kagesi namuhla. Kulesi sihloko, sizohlola umqondo we-MCB futhi sihlole izici zayo, amakhono, kanye nezinzuzo.
KuyiniI-Miniature Circuit Breaker(i-MCB)?
I-miniature circuit breaker, njengoba negama lisho, iyi-miniature circuit breaker esetshenziselwa ukuvikela amasekethe kagesi ekugcwaleni ngokweqile kanye namasekethe amafushane.Ama-MCBngokuvamile zisetshenziswa ezisetshenziswayo ze-voltage ephansi lapho ama-current amaphutha emancane khona.
Wenza njaniama-circuit breaker amancaneumsebenzi?
Ama-MCB aklanyelwe ukuthola amaphutha kumasekethe kagesi nokuphazamisa ukuhamba kwamanje lapho kutholwa iphutha. Umgomo wawo osebenzayo umphumela we-electromagnetic wamanje kagesi. Ngesikhathi sokusebenza okuvamile, ugesi ugeleza ngokuxhumana okuhambayo okuxhunywe kwi-bimetal. Umshini we-bimetallic uqukethe izinsimbi ezimbili ezine-coefficients ehlukene yokwandisa. Lapho ugesi odlula kumugqa udlula umkhawulo othile, ukhiqiza ukushisa bese umugqa we-bimetallic ugoba. Lesi senzo sikhulula indlela yokuhamba, siphazamise ukuhamba kwamanje, ngaleyo ndlela sivikele umjikelezo ekulimaleni.
Izici zama-miniature circuit breakers
Usayizi omncane: Usayizi omncane weI-MCBkwenza kube kuhle kakhulu ekufakweni kukagesi okuncane.
Ukulula Kokufaka: Umklamo we-MCB ojwayelekile wenza kube lula ukuwufaka ngaphandle kwamathuluzi akhethekile.
Ukunemba: Ama-MCB anembe kakhulu ekutholeni ama-fault currents ngoba asabela ngokushesha kunoma yimuphi u-overcurrent osesekethe.
Umthamo wokwephuka okuphezulu: Ama-Miniature circuit breaker anomthamo wokwephuka okuphezulu kwe-short-circuit futhi afanele ukusetshenziswa kwe-low voltage.
Izinzuzo zeAma-Miniature Circuit Breakers
Izindleko Ezingabizi: Ama-MCB asebenza kahle futhi ahlinzeka ngokuvikelwa kukagesi okuthembekile kumasekethe.
Kulula ukuyisetha kabusha: I-MCB ingasethwa kabusha kalula ngemva kokuthola iphutha, okusindisa isikhathi nomzamo.
Ukukhubeka ngokukhetha: I-miniature circuit breaker inekhono lokukhetha ukukhubeka, okungukuthi, i-miniature circuit breaker eseduze kakhulu nokukhubeka kwe-fault point, ngaleyo ndlela inciphisa umthelela we-fault.
Ihlala Isikhathi Eside: Ama-Miniature circuit breaker ahlala isikhathi eside futhi angakwazi ukumelana nezimo ezinzima ukuze ahlinzeke ngesivikelo esithembekile sezinhlelo zikagesi.
Ekuphetheni
Ekuphetheni, i-MCB iyithuluzi elibalulekile elinganikeza isivikelo esiyisisekelo samasekethe. Angabizi kakhulu, kulula ukuwafaka futhi athola amaphutha ngokunemba okuphezulu. Ama-MCB ayisinqumo sokuqala sezinhlelo zokusebenza eziningi ze-voltage ephansi ngenxa yobukhulu bawo obuncane kanye nomthamo omkhulu wokuphuka kwamasekethe amafushane. Ama-MCB abelokhu ekhona iminyaka eminingana futhi ahlala eshintsha ngezici ezithuthukisiwe kanye nobuhle bobuchwepheshe. Ngakho-ke, ukukhetha i-MCB efanele yesistimu yakho kagesi kubalulekile ekugcineni ukuphepha, ukuthembeka kanye nokusebenza kahle.
