Abaphuli beesekethe ezincinci(MCBs) zizixhobo ezibalulekileyo kwiinkqubo zombane zanamhlanje.Ikhusela iisekethe ngokucima amandla ngokuzenzekelayo xa kukho ukugqithisa okanye isiphaluka esifutshane.Ii-MCBs ziqhele ukusetyenziswa kwiindawo zokuhlala, zorhwebo kunye nezoshishino.Ziza kwiindidi ezininzi kwaye zineepropati ezahlukeneyo, kodwa enye yezona zinto ziqhelekileyo ze-MCBs zincinci.Le bhlog iya kukhanyisela ekusebenziseni i-MCB kwiindawo ezahlukeneyo kunye nezilumkiso zokugcina engqondweni.
Ingcaciso yeMveliso
Ii-breaker circuit encincikuya kuxoxwa ngayo kule bhlog inomthamo ophezulu wokuqhawula, umgca we-zero uvutha ngokukhawuleza, kwaye usenokukhusela ukuvuza kwangoku xa umgca ophilayo ubuyiselwa umva.Ubungakanani bayo obuncinci kunye noyilo lwangaphakathi lwentonga ye-double-rod luyenza isebenze ekusebenzeni okungaqhelekanga kunye nokulawula.Iipali zimbini ziyacinywa kwaye zicinywe ngaxeshanye, nto leyo ekhuselekileyo kuzo zombini izigaba zenkqubo yentlalo kunye neyeshishini.
Indawo yokusetyenziswa kwemveliso
Abaphuli beesekethe ezincincizisetyenziswa kwiindawo ezahlukeneyo zokuhlala, zorhwebo kunye nezoshishino.Kwindawo yokuhlala, ii-MCBs zikhusela ukugqithiswa kombane okanye iisekethe ezimfutshane kwiisekethe ezithile ekhaya.Ngokufanayo, ii-MCBs zinokusetyenziswa kwizakhiwo zorhwebo ukukhusela izixhobo ezizimeleyo okanye amaqela ezixhobo, ezifana neekhompyutha okanye ukukhanya.Kwiimeko zoshishino, ii-MCBs zisetyenziselwa ukukhusela izixhobo ezinkulu ezinjengoomatshini okanye iimoto.
Imiqathango yokusetyenziswa
Ngelixa ii-MCBs zibonelela ngokhuseleko kwiinkqubo zombane, nazo zifuna ukusebenza ngokufanelekileyo kunye nokugcinwa kwazo ukuze kuqinisekiswe inkqubo ekhuselekileyo nethembekileyo.Nazi ezinye izilumkiso onokuthi uzithathe xa usebenzisa iziqhekezi zesekethe ezincinci:
- Khetha umlinganiselo ochanekileyo - I-MCB kufuneka ilinganiswe ukuhambelana nokusetyenziswa kwamandla kwesixhobo.
- Sebenzisa uhlobo olufanelekileyo - ii-MCBs ziza kwiindidi ezahlukeneyo ezifana noHlobo lwe-B, uhlobo lweC kunye noHlobo lwe-D. Qinisekisa ukuba ukhetha uhlobo oluchanekileyo ukukhusela izixhobo zakho ekukhubekeni ngokungeyomfuneko.
- Musa ukulayisha kakhulu - Ukulayisha ngaphezulu kwe-MCB kuya kuchaphazela ukusebenza kwayo kwaye kunokubangela ukuba i-breaker circuit ihambe ngokungeyomfuneko.
- Ukuhlolwa kwamaxesha ngamaxesha - Hlola rhoqo imeko ye-MCB ngokukhululeka okanye iimpawu ezicacileyo zokugqoka.
- Gcina kwindawo evaliweyo - Qinisekisa ukuba ii-MCBs zifakwe kwindawo evaliweyo ukuze ugweme ukuphazamisana nazo okanye ukuzibeka esichengeni sokufuma, ubushushu, okanye ezinye izinto eziyingozi.
ukuququmbela
Ukuqukumbela, abaphuli beesekethe ezincinci bayinxalenye ebalulekileyo yeenkqubo zombane.Zikhusela ekugqithiseni kunye neesekethe ezimfutshane.Ii-MCBs ezixutyushwa kule bhlog zinomthamo ophezulu wokuqhawula kunye noyilo lokwakhiwa kweepali ezimbini ezenza zibe zizodwa kwaye zixabiseke njengesisombululo kwiimfuno zakho zokukhusela umbane.Ukuba ufuna ukusebenzisa i-MCB, khumbula ukuthatha amanyathelo okhuseleko ayimfuneko kwaye uyikhathalele ukuqinisekisa ukuba iya kugcina inkqubo yakho yombane ikhuselekile kwaye ikhuselekile.
