Iintlobo ze-Circuit Breaker kunye neSikhokelo soKhetho

UkuqondaAbaphuli beeSeketheIzixhobo zoKhuseleko ezibalulekileyo kwiinkqubo zombane

Igama elithi “i-circuit breaker” liqhelekile kwihlabathi lobunjineli bombane kunye nokhuseleko lwasekhaya. Ii-circuit breaker zizinto ezibalulekileyo ezikhusela ii-electrical circuits kwi-overloads kunye ne-short circuits, ziqinisekisa ukhuseleko lweenkqubo zombane kunye nabo bazisebenzisayo. Eli nqaku liza kujonga ngokusondeleyo umsebenzi, iintlobo, kunye nokubaluleka kwee-circuit breakers kwiinkqubo zombane zanamhlanje.

Yintoni i-circuit breaker?

I-circuit breaker sisitshixo sombane esizenzekelayo esithintela ukuhamba kombane kwisekethe xa sibona imeko engaqhelekanga, efana nokugqithisa okanye i-short circuit. Ngokungafaniyo nee-fuse, ekufuneka zitshintshwe emva kokuba zivuthuzekile, ii-circuit breakers zinokusetwa kwakhona emva kokuba zikhubekile, nto leyo eyenza zibe lukhetho olulula nolusebenzayo lokukhusela ii-circuit. Ii-circuit breakers zibalulekile ekuthinteleni imililo yombane, umonakalo kwizixhobo, kunye nezinye iingozi ezinxulumene nokungasebenzi kakuhle kombane.

Indlela abaphuli beesekethe abasebenza ngayo

Ii-circuit breakers zisebenza ngokusekelwe kwiindlela ezimbini eziphambili: i-thermal kunye ne-magnetic.

1. Indlela yokukhusela ubushushu: Le ndlela isebenzisa umcu we-bimetallic ogobayo xa umcu uphezulu kakhulu. Xa umcu udlula ixabiso elimiselweyo, umcu wesinyithi ugoba ngokwaneleyo ukuze uqalise i-circuit breaker, ngaloo ndlela unqumle umcu wesekethe.

2. Indlela esebenza ngemagnethi: Le ndlela isebenza ixhomekeke kumandla e-electromagnetic. Xa kwenzeka i-short circuit, ukungena ngokukhawuleza kwamandla e-current kudala amandla emagnethi anamandla ngokwaneleyo okutsala i-lever kunye nokuwisa i-circuit breaker.

Ezinye ii-circuit breakers zanamhlanje zidibanisa zombini iindlela zokukhusela okuphuculweyo, zibonelela ngempendulo ethembekileyo ngakumbi kwiingxaki ezahlukeneyo zombane.

Iintlobo zee-circuit breakers

Kukho iintlobo ezahlukeneyo zee-circuit breakers, nganye inenjongo ethile:

1. IiMiniature Circuit Breakers (MCB): Ezi circuit breakers zisetyenziswa kakhulu kwizakhiwo zokuhlala nezorhwebo ukukhusela ukugqithisa kunye nee-short circuits. Zincinci kwaye zinokuphatha amanqanaba ombane aphantsi ukuya kwaphakathi.

2. I-Residual Current Breaker (RCCB): Ezi zixhobo zithintela ukutshayiswa kombane ngokufumanisa ukungalingani kwamandla ombane. Ukuba kufunyenwe impazamo, i-RCCB iya kukhubeka ize iwucime umbane.

3. IiResidual Current Breakers (ELCB): NjengeResidual Current Breakers (RCCB), ii-ELCB zikhusela kwiingxaki zomhlaba. Zibaluleke kakhulu kwiindawo ezimanzi ezifana nezindlu zangasese kunye neekhitshi.

4. Ii-Air Circuit Breakers (ACB): Ii-air circuit breakers zisetyenziswa kwimizi-mveliso ukujongana namanqanaba aphezulu ombane kunye nokukhusela kwi-overload, short circuit, kunye ne-ground failure.

5. IiHydraulic Magnetic Circuit Breakers: Ezi zihlala zisetyenziswa kwiinkqubo zombane ezinkulu kwaye zibonelela ngesisombululo esiqinileyo sokukhusela kwimisinga ephezulu yempazamo.

Ukubaluleka kwabaPhuli beeSekethe

Ukubaluleka kweziphuli zesekethe akunakugxininiswa kakhulu. Ziyindlela yokuqala yokuzikhusela kwiingozi zombane, zikhusela ubomi kunye nepropathi. Iziphuli zesekethe zinqumla ngokuzenzekelayo ukuhamba kombane kwiimeko eziyingozi, zinceda ekuthinteleni imililo yombane, umonakalo wezixhobo, kunye nokwenzakala komntu.

Ukongeza, ii-circuit breakers zinceda ekuphuculeni ukusebenza kakuhle kweenkqubo zombane. Ngokuthintela ukugqithiswa kakhulu, ii-circuit breakers ziqinisekisa ukuba izixhobo zombane zisebenza ngaphakathi kwemida ekhuselekileyo, ngaloo ndlela zandisa ubomi benkonzo yazo kwaye zinciphise iindleko zokulungisa.

Isishwankathelo

Lilonke, ii-circuit breakers ziyinxalenye ebalulekileyo yeenkqubo zombane zanamhlanje. Ukukwazi kwazo ukubona nokuphendula kwiimpazamo zombane kubalulekile ukuze kukhuseleke kwaye kusebenze kakuhle. Ukuqonda iintlobo ezahlukeneyo zee-circuit breakers kunye nemisebenzi yazo kunokunceda abanini bezindlu kunye namashishini ukuba benze izigqibo ezinolwazi malunga neenkqubo zabo zombane. Njengoko iteknoloji iqhubeka ihambela phambili, ii-circuit breakers ngokuqinisekileyo ziya kuqhubeka zitshintsha, ziphucula ngakumbi indima yazo ekukhuseleni iziseko zethu zombane.
