Iintlobo ze-Circuit Breaker kunye neSikhokelo soKhetho

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 zisetyenziselwa iinjongo zokuhlala kunye nezorhwebo ukukhusela ukugqithisa kunye nee-short circuits. Ii-MCB zine-voltage rating ephantsi kwaye zihlala zisetyenziswa kwiindawo zokufakelwa kwabathengi.

2. IiResidual Current Breakers (RCCBs)**: Ezi circuit breakers, ezaziwa ngokuba ziiResidual Current Devices (RCDs), zenzelwe ukuthintela ukutshayiswa kombane ngokubona ukungalingani kwamandla ombane. Ukuba umntu uchukumisa ucingo oluphilayo, iRCCB 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-industrial high voltage. Ii-ACB zinokuphatha imisinga ephezulu kwaye zihlala zisetyenziswa kwizikhululo ezincinci nakwizakhiwo ezinkulu zorhwebo.

5. IiHydraulic Magnetic Circuit Breakers: Ezi circuit breakers zisebenzisa indibaniselwano yeendlela zobushushu kunye nemagnethi ukusika icircuit. Zisetyenziswa kakhulu kwiiphaneli zombane zokuhlala.

Ukubaluleka kwee-circuit breakers akunakugxininiswa kakhulu. Zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko lwezixhobo zombane, zithintela ukugqithiswa okunokubangela imililo kunye nokusilela kwezixhobo. Ukongeza ekukhuseleni ubomi kunye nepropathi, ii-circuit breakers zinceda ekugcineni ukuthembeka kweenkqubo zombane, ukunciphisa ixesha lokungasebenzi kunye neendleko zokulungisa.

Kwiminyaka yakutshanje, inkqubela phambili kwezobuchwepheshe ikhokelele ekuphuhlisweni kwee-smart circuit breakers. Ezi zixhobo zinokunxibelelana neenkqubo ze-automation zasekhaya, zivumela abasebenzisi ukuba bajonge ukusetyenziswa kwamandla ngexesha langempela kwaye bafumane izilumkiso ukuba kukho impazamo. Ii-Smart circuit breakers ziphucula ukhuseleko kunye nokusebenza kakuhle, zizenza zibe lukhetho olunomtsalane kumakhaya nakumashishini anamhlanje.

Xa ukhetha i-circuit breaker, izinto ezinje ngomthwalo wombane, uhlobo lokhuseleko olufunekayo, kunye nokusetyenziswa okuthile kufuneka kuqwalaselwe. Ukufakelwa ngokufanelekileyo kunye nokugcinwa rhoqo kubalulekile ukuqinisekisa ukuba i-circuit breaker isebenza ngokufanelekileyo. Abanini bezindlu kunye nabaphathi bezakhiwo kufuneka bavavanye rhoqo i-circuit breakers baze batshintshe naziphi na ezibonisa iimpawu zokuguguleka okanye ukungasebenzi kakuhle.

Ngamafutshane, i-circuit breaker sisixhobo sokhuseleko esibalulekileyo esikhusela iinkqubo zombane kwi-overloads kunye ne-short circuits. I-circuit breakers ziza kwiindidi ezininzi zezicelo ezahlukeneyo kwaye zidlala indima ebalulekileyo ekukhuseleni ubomi kunye nepropathi. Ikamva le-circuit breakers libonakala liqaqambile njengoko ubuchwepheshe buqhubeka buhambela phambili, kunye nophuhliso oluphucula ukusebenza kwazo kunye nokusebenza kakuhle. Ukuqonda ukubaluleka kwe-circuit breakers kubalulekile kuye nabani na obandakanyekayo ekufakweni kombane, nokuba kukwiindawo zokuhlala, zorhwebo, okanye kwimizi-mveliso.
