Ukuqonda ii-MCBs (iMiniature Circuit Breakers)-Isebenza njani kwaye kutheni ibalulekile kuKhuseleko lweSekethe

Ehlabathini leenkqubo zombane kunye neesekethe, ukhuseleko lubaluleke kakhulu.Enye yezinto eziphambili zokuqinisekisa ukhuseleko lwesekethe kunye nokukhuselwa yiI-MCB (i-breaker circuit encinci).Ii-MCBs ziyilelwe ukuba zivale ngokuzenzekelayo iisekethe xa kubhaqwa iimeko ezingaqhelekanga, zithintela iingozi ezinokubakho ezifana neesekethe ezimfutshane kunye nemililo yombane.

Ke, isebenza njani kanye kanye i-MCB?Makhe sihlolisise ukusebenza kwangaphakathi kwesi sixhobo sibalulekileyo.Kukho iintlobo ezimbini zoqhagamshelwano ngaphakathi kwe-MCB - enye ilungisiwe kwaye enye iyasuswa.Ngaphantsi kweemeko eziqhelekileyo zokusebenza, aba bafowunelwa bahlala benxibelelana, bevumela ukuba i-current ihambe kwisiphaluka.Nangona kunjalo, xa ukwanda kwangoku ngaphaya komthamo olinganisiweyo wesekethe, oonxibelelwano abashukumayo baphoqeleka ukuba banqanyulwe kubafowunelwa abasisigxina.Esi senzo ngokuphumelelayo "sivula" isiphaluka, sinqumle i-current kunye nokuthintela nawuphi na umonakalo okanye ingozi enokwenzeka.

Ikhono le-MCB lokubona ngokukhawuleza nangokuchanekileyo ngoku ngokugqithisileyo kunye nokuphendula ngokukhawuleza ukuvala isiphaluka kwenza kube yinto efunekayo kwiinkqubo zombane.Isiphaluka esifutshane senzeke xa kukho uxhulumaniso lwengozi phakathi kweengcingo ezishushu kunye nezingathathi hlangothi, ezinokubangela ukunyuka ngokukhawuleza kwangoku.Ukuba ayifakelwanga i-MCB, umsinga ogqithisileyo oveliswa sisikethi esifutshane unokubangela ukushisa, ukunyibilika kwezinto zokugquma, okanye imililo yombane.Ngokuphazamisa ngokukhawuleza isekethe xa kusenzeka isiphaluka esifutshane, iizaphuli zesekethe ezincinci zidlala indima ebalulekileyo ekuthinteleni iintlekele ezinokubakho.

Ukongeza kwiisekethe ezimfutshane, ii-MCBs zikwakhusela kwezinye iziphene zombane ezifana nokugcwala kunye nokuvuza.Ukulayisha ngaphezulu kwenzeka xa isekethe igcwele kakhulu, itsala umsinga omninzi kakhulu, kwaye ukuvuza kwenzeka xa kukho indlela ebingacetywanga eya emhlabeni, enokuthi ibe nesiphumo sokothuka kombane.Ii-MCBs ziyakwazi ukubona kwaye ziphendule ezi mpazamo, zibonelela ngokhuseleko olongezelelweyo kwinkqubo yombane kunye nabantu abayisebenzisayo.

Ukubaluleka kwe-MCB akukho kuphela kumsebenzi wayo;Ubungakanani bayo obuncinci kunye nokulula kofakelo kwenza kube yinto yokuqala yokukhusela isiphaluka.Ngokungafaniyo neefusi zesiNtu, ii-MCBs zinokusetwa kwakhona emva kokukhubeka, kushenxiswa imfuno yokutshintshwa qho xa kukho impazamo.Oku akugcini nje ukugcina ixesha kunye nomgudu, kodwa kunciphisa iindleko zokugcina kunye nokubuyisela.

Ekugqibeleni, ii-MCBs ngamagorha angaziwayo okhuseleko lombane, asebenza ngokuzolileyo emva kwemiboniso ukukhusela iisekethe kunye nabantu abaxhomekeke kubo.Ii-MCBs ziyakwazi ukuphendula ngokukhawuleza kwiimeko ezingaqhelekanga kwiisekethe kwaye ziyingxenye ebalulekileyo ekugcineni ukhuseleko kunye nokunyaniseka kweenkqubo zombane.Ingaba kwindawo yokuhlala, yorhwebo okanye yoshishino, ubukho be-MCB buqinisekisa ukuba iziphene zombane zisonjululwa ngokukhawuleza, ukunciphisa umngcipheko womonakalo kunye nobungozi obunokwenzeka.Njengoko itekhnoloji iqhubeka nokuhambela phambili, i-miniature breakers ngokungathandabuzekiyo iya kuhlala ilitye lembombo lokhuseleko lwesekethe, ikunika uxolo lwengqondo kunye nokuqinisekisa ukuqhubeka kobonelelo lwamandla.
