Iziqhekeza zesekethe ezincinci (MCBs)ziyinxalenye ebalulekileyo yesixokelelwano sakho sombane, ukukhusela ikhaya lakho okanye ishishini kwiisekethe ezimfutshane kunye nokugcwala.Zincinci, zilula ukuzifaka kunye nokubonelela ngokukhawuleza nangokuthembekileyo ukhuseleko lombane.Ii-MCBszisetyenziswa kakhulu kumakhaya, izakhiwo zorhwebo kunye nezicwangciso zoshishino ukukhusela imililo yombane kunye nezinye iimeko ezinobungozi.Kule bhlog, siza kuntywila nzulu kweminye imiba ephambili yeIi-MCBs, zisebenza njani, kwaye kutheni ziyinxalenye ebalulekileyo yesixokelelwano sakho sombane.
Ndingenza njanii-miniature circuit breakers isebenza?
I-MCB ngokusisiseko lutshintsho oluhamba ngokuzenzekelayo xa ibona i-overcurrent okanye i-overload kwisekethe.Xa i-current idlula ireyithingi yayo, ibangela ukuba i-thermal or magnetic elements kwi-MCB ihambe kwaye iphazamise ukuhamba kwangoku.I-MCB yenzelwe ukuhamba ngokukhawuleza, ngokuqhelekileyo ngaphakathi kwemizuzwana, xa i-overload okanye isiphaluka esifutshane sifunyenwe.Emva kokuba isekethe ikhutshiwe, iphazamisa ukuhamba kombane ngokusebenzisa isiphaluka esinempazamo kwaye inceda ukuthintela umonakalo kwisixhobo sombane kunye nemililo yombane enokwenzeka.
Iimpawu ezibalulekileyo zeMCB
Xa ukhetha iMCB, kukho iimpawu ezininzi ezibalulekileyo ekufuneka ziqwalaselwe, kubandakanywa uhlobo lwe-circuit breaker, ukulinganisa kwangoku, amandla okuphazamisa, kunye ne-curve curve.Uhlobo lwe-breaker circuit lufanele lufaneleke kwisistim sombane kunye nesixa sangoku esisiphetheyo.Ireyithingi yangoku imisela ukuba yimalini yangokuMCBinokusingatha phambi kokukhubeka, ngelixa umthamo wokuqhawula ubuninzi besiphoso sangoku esinokuthi i-MCB iphule ngokukhuselekileyo.I-curve yohambo ibaluleke kakhulu njengoko imisela ukuba i-MCB iphendula ngokukhawuleza kangakanani kwi-overload okanye isiphaluka esifutshane kwaye ineengqungquthela ezintathu eziphambili - i-B curve yemithwalo esemgangathweni, i-C curve ye-motor kunye ne-D curve for transformers power.
Ukugqithiswa kunye nokukhusela isiphaluka esifutshane
Ukukhuselwa kokugqithiswa ngumsebenzi ophambili weMCBkwinkqubo yombane.Ikhusela izixhobo zakho kunye neengcingo ekutshiseni kakhulu ngenxa yangoku ngokugqithisileyo.Ukukhuselwa kwesiphaluka esifutshane ngomnye umsebenzi obalulekileyo wee-breaker circuits ezincinci.Isiphaluka esifutshane senzeke xa kukho indlela ethe ngqo phakathi komthombo kunye nomthwalo, okubangelwa ukuhamba ngokugqithisileyo kwangoku kunye nomngcipheko omkhulu womlilo wombane.Kule meko inobungozi, i-MCB ihamba ngokukhawuleza, ikhusela ukuhamba okuqhubekayo kwangoku kunye nokukhusela inkqubo kumonakalo onokwenzeka.
ukuququmbela
Ukuququmbela,MCByinxalenye eyimfuneko nebalulekileyo kwinkqubo yombane.Bakhusela ikhaya lakho okanye ishishini kwi-overload kunye neesekethe ezimfutshane, ukukhusela izixhobo zakho kunye nokuphepha iimeko ezinokuba yingozi.I-MCB efanelekileyo kufuneka ikhethelwe isiphaluka sakho, kuthathelwa ingqalelo izinto ezifana ne-rate yangoku, ukuphazamisa umthamo kunye ne-curve yohambo.Ukugcinwa rhoqo kunye nokuhlolwa kwe-MCBs yakho kuya kuqinisekisa ukuba bayaqhubeka nokwenza imisebenzi yabo ebalulekileyo ngokufanelekileyo, ukukhusela inkqubo yakho yombane kunye nokuqinisekisa ukhuseleko.
