Ugesi uwumthombo wamandla obalulekile emisebenzini yethu yansuku zonke.Kodwa-ke, ngaphezu kwezinzuzo zayo, ingaba nezingozi ezinkulu uma ingaphathwa kahle.Yingakho ukuba nama-circuit breaker athembekile kubalulekile ekugcineni amasistimu ethu kagesi ephephile.I-miniature circuit breaker (I-MCB) ingenye yezinto ezinjalo ezisetshenziswa kakhulu kwezobunjiniyela bakagesi namuhla.Kulesi sihloko, sizohlola umqondo we-MCB futhi sihlole izici zayo, amakhono, kanye nezinzuzo.
Yini aI-Miniature Circuit Breaker(MCB)?
I-circuit breaker encane, njengoba negama liphakamisa, i-breaker circuit encane esetshenziselwa ukuvikela amasekhethi kagesi ekulayisheni ngokweqile namasekhethi amafushane.Ama-MCBsngokuvamile asetshenziswa ku-low voltage izicelo lapho iphutha imisinga mincane.
Wenza njaniama-breaker circuit amancaneumsebenzi?
Ama-MCB aklanyelwe ukubona amaphutha kumasekhethi kagesi futhi aphazamise ukugeleza kwamanje lapho kutholwa iphutha.Umgomo wayo wokusebenza wumphumela we-electromagnetic wamanje kagesi.Ngesikhathi sokusebenza okuvamile, okwamanje kugeleza kothintana naye osuswayo oxhunywe ku-bimetal.I-bimetallic strip iqukethe izinsimbi ezimbili ezinama-coefficients ahlukene wokunweba.Uma i-current through the strip idlula umkhawulo othile, ikhiqiza ukushisa futhi i-bimetallic strip iyagoba.Lesi senzo sikhulula indlela yohambo, iphazamisa ukugeleza kwamandla, ngaleyo ndlela ivikele isifunda emonakalweni.
Izici zama-circuit breaker amancane
Usayizi ohlangene: Usayizi ohlangene we-I-MCBkwenza kube kuhle ekufakeni ugesi okuncane.
Ukufaka kalula: Idizayini ye-MCB yenza kube lula ukuyifaka ngaphandle kwamathuluzi akhethekile.
Ukunemba: Ama-MCB anembe kakhulu ekutholeni ama-currents amaphutha ngoba aphendula ngokushesha kunoma iyiphi i-overcurrent kusekethe.
Umthamo omkhulu wokuphuka: Ama-circuit breaker amancane anomthamo omkhulu wokuphuka wesekethe emfishane futhi afanele izinhlelo zokusebenza zamandla aphansi.
Izinzuzo zeAma-Miniature Circuit Breakers
Izindleko: Ama-MCB ayabiza futhi ahlinzeka ngokuvikela okuthembekile kukagesi kumasekhethi.
Kulula ukusetha kabusha: I-MCB ingasethwa kabusha kalula ngemva kokuthola iphutha, ukonga isikhathi nomzamo.
Ukukhubeka okukhethayo: I-circuit breaker encane inamandla okukhubeka, okungukuthi, isihlukanisi sesekhethi esincane esiseduze nohambo lwephoyinti lephutha, ngaleyo ndlela sinciphise umthelela wephutha.
Okuhlala isikhathi eside: Ama-circuit breaker amancane anempilo ende yesevisi futhi angamelana nezimo ezinzima ukuze anikeze ukuvikeleka okuthembekile kwamasistimu kagesi.
Ekuphetheni
Sengiphetha, i-MCB iyisisetshenziswa esibalulekile esinganikeza ukuvikeleka okuyisisekelo kwamasekhethi.Ayabiza, kulula ukuwafaka futhi abone amaphutha ngokunemba okuphezulu.Ama-MCB ayinketho yokuqala yezinhlelo zokusebenza eziningi zamandla kagesi aphansi ngenxa yobukhulu bawo obuhlangene kanye nomthamo omkhulu wokuphulwa kwesekethe emfushane.Ama-MCB abekhona iminyaka eminingana futhi ahlala ethuthuka anezici ezithuthukile kanye nobuchwepheshe obusezingeni eliphezulu.Ngakho-ke, ukukhetha i-MCB efanele yohlelo lwakho lukagesi kubalulekile ekugcineni ukuphepha, ukwethembeka nokusebenza kahle.
