Abaphuli beesekethe: Ukhuseleko kunye noKhuselo lwaMandla

UkuqondaAbaphuli beeSekethe: Amaqhawe Angadunyiswanga Okhuseleko Lombane

Iziphuli zesekethe zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokusebenza kweenkqubo zombane. Ezi zixhobo zenzelwe ukukhusela iisekethe zombane kwimithwalo emininzi kunye neesekethe ezimfutshane njengokhuseleko kwiingozi ezinokubakho. Ukuqonda indlela ezisebenza ngayo iziphuli zesekethe, iintlobo zazo, kunye nokubaluleka kwazo kunokunceda abanini bezindlu kunye neengcali ukugcina imeko-bume yombane ekhuselekileyo.

Yintoni i-circuit breaker?

I-circuit breaker sisitshixo sombane esizenzekelayo esiphazamisa ukuhamba kombane kwisekethe xa sibona imeko engaqhelekanga, efana nokugqithiswa kakhulu 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 isekethe.

Zisebenza njani ii-circuit breakers?

Umgaqo osebenzayo wee-circuit breakers ulula: zijonga umbane ohamba kwi-circuit. Xa umbane udlula umda obekiweyo, i-circuit breaker iyakhubeka, inqumle umbane. Eli nyathelo lithintela ubushushu obugqithisileyo kunye nemililo enokubakho ebangelwa ngumbane ogqithisileyo. Le ndlela idla ngokubandakanya uhambo olushushu okanye inkqubo ye-magnetic trip.

- Iziphuli zesekethe ezishushu: Ezi ziphuli zesekethe zisebenzisa umcu we-bimetallic ogobayo xa ushushu ngumbane ogqithisileyo, ekugqibeleni ubangele iswitshi yokuvula isekethe.

- Abaphuli beesekethe ze-electromagnetic: Abaphuli beesekethe bajongana nokunyuka ngequbuliso kombane, njengalowo ubangelwa yi-short circuit. Basebenzisa i-electromagnet ukutsala i-lever, bephula i-circuit phantse ngoko nangoko.

Iintlobo zee-circuit breakers

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

1. Isixhobo sokwaphula iisekethe esiqhelekileyo: Sifumaneka rhoqo kwiindawo zokuhlala, sisetyenziselwa ukukhusela kwiingxaki zokugqithisa kunye neesekethe ezimfutshane.

2. IiGround Fault Circuit Interruptors (GFCI): Zibalulekile kwiindawo ezimanzi ezifana nezindlu zangasese kunye neekhitshi njengoko zinokubona iimpazamo zomhlaba kwaye zithintele ukutshayiswa ngumbane.

3. Ii-Arc Fault Circuit Interrupters (AFCI): Zenzelwe ukuthintela imililo yombane ebangelwa ziimpazamo ze-arc, ezi circuit breakers ziya zithandwa kakhulu kumakhaya anamhlanje.

4. I-Miniature Circuit Breaker (MCB): Isetyenziswa kwizicelo ze-voltage ephantsi kwaye ikhusela ukugqithisa.

5. I-Residual Current Breaker (RCCB): Ibona ukungalingani komsinga kwaye ibalulekile ekuthinteleni ukutshayiswa kombane.

Ukubaluleka kwabaPhuli beeSekethe

Ukubaluleka kwee-circuit breakers akunakugxininiswa kakhulu. Zibalulekile kwezi zinto zilandelayo:

- Ukhuseleko: Iziphuli zesekethe zikhusela ubomi kunye nempahla ngokuthintela imililo yombane kunye nokutshayiswa kombane.

- KULUNGILE: Ngokungafaniyo neefusi ezifuna ukutshintshwa, ii-circuit breakers zinokusetwa kwakhona ngokulula, nto leyo enciphisa ixesha lokungasebenzi.

- Ixabiso eliphantsi: Nangona utyalo-mali lokuqala lunokuba phezulu kunee-fuse, ii-circuit breakers zonga imali ekuhambeni kwexesha kuba zinciphisa umngcipheko wokonakala kombane kunye nesidingo sokutshintshwa rhoqo.

- Ukuthobela imithetho: Iikhowudi ezininzi zokwakha zifuna ukufakwa kwee-circuit breakers, ngakumbi i-GFCI kunye ne-AFCI, ukuqinisekisa ukuba imigangatho yokhuseleko iyafezekiswa.

Okukwintsusa

Ngamafutshane, ii-circuit breakers ziyinxalenye ebalulekileyo yeenkqubo zombane zanamhlanje, zibonelela ngokhuseleko olusisiseko kwiingxinano ezinkulu kunye nee-short circuits. Ziyakwazi ukuphinda zisetyenziswe emva kokukhubeka, nto leyo eyenza zibe lukhetho olusebenzayo kwiindawo zokuhlala kunye nezorhwebo. Ukuqonda iintlobo ezahlukeneyo zee-circuit breakers kunye nemisebenzi yazo kuvumela abantu ukuba benze izigqibo ezinolwazi malunga nokhuseleko lombane emakhayeni abo nakwiindawo zokusebenza. Njengoko ubuchwepheshe buqhubela phambili, ii-circuit breakers ziya kuqhubeka nokukhula, ziphucula ngakumbi indima yazo njengeeqhawe ezingadunyiswanga zokhuseleko lombane.
