Abaphuli beesekethe: Isitshixo soKhuseleko lwaMandla

UkuqondaAbaphuli beeSeketheIzixhobo zoKhuseleko ezibalulekileyo kwiinkqubo zombane

Iziphuli zesekethe zizinto ezibalulekileyo kwiinkqubo zombane, zisebenza njengezixhobo zokukhusela ekonakaleni ngenxa yokugqithisa kakhulu kunye neesekethe ezimfutshane. Zenzelwe ukuphazamisa ngokuzenzekelayo ukuhamba kombane xa kufunyenwe impazamo, ukuqinisekisa ukhuseleko lwenkqubo yombane kunye nabo bayisebenzisayo. Eli nqaku lijonga ngokunzulu umsebenzi, iintlobo, kunye nokubaluleka kweziphuli zesekethe kwiinkqubo zombane zanamhlanje.

I-circuit breaker ngokuyintloko sisitshixo esivula size sivale i-electrical circuit. Ngokungafaniyo ne-fuse, ekufuneka itshintshwe emva kokuba ivuthuze, i-circuit breaker inokuphinda isetyenziswe emva kokuba ikhubekile, nto leyo eyenza ukuba ibe lukhetho lokukhusela umbane olulula nolusebenzayo. Xa kuvela impazamo yombane, efana ne-short circuit okanye i-overload, i-circuit breaker ibona ukuhamba kombane okungaqhelekanga kwaye iphazamise i-circuit, ithintela iingozi ezinokubakho ezifana nemililo yombane okanye umonakalo wezixhobo.

Kukho iintlobo ezininzi zee-circuit breakers, nganye yenzelwe usetyenziso oluthile kunye neendawo ezithile. Ezona ntlobo zixhaphakileyo ziquka:

1. I-Miniature Circuit Breaker (MCB)Ezi circuit breakers zisetyenziswa kwiindawo zokuhlala nakwiindawo zorhwebo ukukhusela ukugqithisa kakhulu kunye nee-short circuits. Ii-MCB zincinci kwaye zinokufakwa lula kwiibhodi zokusasaza.

2. IiResidual Current Breakers (iiRCCB): Ezi circuit breakers, ezaziwa ngokuba ziResidual Current Devices (RCDs), zenzelwe ukuthintela ukutshayiswa kombane ngokubona ukungalingani kwamandla ombane. Ukuba umntu uchukumisa ucingo oluphilayo, i-RCCB iya kukhubeka, inqumle umbane.

3. I-Leakage Current Circuit Breaker (ELCB): Njenge-RCCB, i-ELCB isetyenziselwa ukubona iimpazamo zomhlaba kunye nokuthintela ukutshayiswa ngumbane. Zibaluleke kakhulu kwiindawo ezimanzi, njengezindlu zangasese kunye neendawo zangaphandle.

4. Ii-Air Circuit Breakers (ACB): Ezi circuit breakers zisetyenziswa kwiinkqubo ze-high voltage zoshishino. Ii-ACB zinokuphatha imisinga ephezulu kwaye zibonelele ngokhuseleko olugqithisileyo nolufutshane kwizixhobo zombane ezinzima.

5. IiHydraulic Magnetic Circuit Breakers: Ezi circuit breakers zisebenzisa indibaniselwano yeendlela zobushushu kunye nemagnethi ukuphula icircuit. Zihlala zisetyenziswa kwiinkqubo zombane ezinkulu ezifuna ulawulo oluchanekileyo.

Ukubaluleka kweziphuli zesekethe akunakugxininiswa kakhulu. Zidlala indima ebalulekileyo ekuqinisekiseni ukuba izixhobo zombane zikhuselekile, zithintela imililo yombane, zikhusela izixhobo ekonakalisweni, kwaye ziqinisekisa ukhuseleko lomntu. Kwindawo yokuhlala, iziphuli zesekethe zihlala ziyindlela yokuqala yokuzikhusela kwiingozi zombane. Zinika abanini bezindlu uxolo lwengqondo, besazi ukuba inkqubo yabo yombane ixhotyiswe ngokhuseleko oluthembekileyo.

Ukongeza kukhuseleko, iziphuli-mbane zikwanceda ekuphuculeni ukusebenza kakuhle kweenkqubo zombane. Ngokuthintela ukugqithiswa kakhulu, iziphuli-mbane zinceda ekugcineni ukuthembeka kwezixhobo zombane, zinciphisa amathuba okulungiswa okubizayo kunye nexesha lokungasebenzi. Oku kubaluleke kakhulu kwiindawo zoshishino, apho ukusilela kwezixhobo kunokubangela ilahleko enkulu yemali.

Njengoko ubuchwepheshe buqhubeka, ii-circuit breakers ziya ziphucuka ngakumbi. Umzekelo, ii-smart circuit breakers zinokudityaniswa kwiinkqubo ze-automation zasekhaya, zivumela abasebenzisi ukuba bajonge kwaye balawule ukusetyenziswa kombane kude. Ezi zinto zintsha aziphuculi nje kuphela ukhuseleko kodwa zikwaphucula nokusebenza kakuhle kwamandla, okuhambelana nomkhwa woyilo lombane olunika ingqalelo ngakumbi ekuzinzeni.

Ngamafutshane, ii-circuit breakers ziyinxalenye ebalulekileyo yeenkqubo zombane zanamhlanje. Zibalulekile ekuqinisekiseni ukhuseleko kwiindawo zokuhlala, zorhwebo, kunye nezicelo zemizi-mveliso kuba zikhusela ekugqithiseni kakhulu kunye nee-short circuits. Njengoko siqhubeka sithembele kumbane kubomi bethu bemihla ngemihla, ukuqonda indima kunye nomsebenzi wee-circuit breakers kuya kusinceda siqonde ukubaluleka kwazo ekugcineni iinkqubo zombane ezikhuselekileyo nezisebenzayo. Nokuba ungumnikazi wendlu, umbane, okanye injineli, ukuqonda ii-circuit breakers kubalulekile ekuqondeni ubunzima bokhuseleko lombane.
