Isihloko: “Iziqhekezi zeSekethe: Ukukhusela iiNkqubo zoMbane ukuze zisebenze kakuhle”
yazisa:
Iziphuli zesekethezidlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokukhuselekileyo nangokufanelekileyo kweenkqubo zombane. Ezi zixhobo zisebenza njengeeswitshi zombane ezizenzekelayo, zibonelela ngendlela yokukhusela kwi-overcurrent kunye ne-short circuits.Iziphuli zesekethekhusela iindawo zokuhlala nezoshishino kwiingozi ezinokubakho kunye nomonakalo wezixhobo ngokuphazamisa ukuhamba kombane xa kuyimfuneko. Kule bhlog, siza kujonga ngokunzulu imisebenzi ye-circuit breaker, iintlobo kunye nokugcinwa kwayo, sichaza ukubaluleka kwayo ekugcineni ukhuseleko lombane.
1. Yintoni i-circuit breaker?
Iziphuli zeseketheziyinxalenye ebalulekileyo yayo nayiphi na inkqubo yombane. Xa umbane udlula umthamo wawo olinganiselweyo, uya kuphazamisa ngokuzenzekelayo umbane, ngaloo ndlela ukhusela inkqubo ekugqithiseni umbane. Oku kuphazamiseka kuthintela umbane ukuba ungatshisi kakhulu kwaye kubangele umlilo okanye enye ingozi yombane. Le ndlela iqinisekisa ukhuseleko kunye nobude bexesha lezixhobo zethu kunye neentambo.
2. Iintlobo zeiziphuli zesekethe:
Kukho iintlobo ezininzi zeiziphuli zeseketheukuze zilungele ukusetyenziswa okwahlukeneyo. Ezona ntlobo zixhaphakileyo ziquka ii-thermal circuit breakers, ii-magnetic circuit breakers, kunye nee-thermal-magnetic circuit breakers. Ii-thermal circuit breakers zixhomekeke kwi-bimetal strip egobayo xa ishushu, nto leyo ebangela ukubaumephuli wojikelezoKwelinye icala, ii-magnetic circuit breakers zisebenzisa i-electromagnetic coil ukuze zivule iswitshi, ngelixa ii-thermal magnetic circuit breakers zidibanisa imisebenzi yee-thermal magnetic circuit breakers. Ukongeza,iziphuli zesekethezinokuhlulwa ngokwe-voltage yazo elinganisiweyo, i-current elinganisiweyo, kunye nokusetyenziswa kwayo (ekhaya, kwezorhwebo, okanye kwimizi-mveliso).
3. Ukubaluleka kokugcinwa rhoqo:
Ukugcina eyakhoumephuli wojikelezoKubalulekile ukuqinisekisa ukusebenza kwayo kakuhle. Ukugcinwa rhoqo kuquka ukuhlola ngokubonakalayo i-circuit breaker ukuze kubonwe iimpawu zokuguguleka okanye zokonakala, ukujonga uqhagamshelo olukhululekileyo, kunye nokuvavanya ukusebenza kwayo. Kucetyiswa ukuba uhlolo oluqhelekileyo lucwangciswe yingcali yombane eqeqeshiweyo ukuqinisekisa ukuba i-circuit breakers zisebenza kakuhle. Ukungahoyi ukugcinwa kunokubangela ukusebenza kakubi kwe-circuit breaker, ukubeka ukhuseleko esichengeni, kwaye mhlawumbi konakalise izixhobo zombane.
4. Indima kaiziphuli zesekethekukhuseleko lombane:
Iziphuli zesekethe ziyindlela yokuqala yokuzikhusela kwiingozi zombane. Ngokuphazamisa ngokukhawuleza umbane xa kukho umbane ogqithisileyo okanye umbane omfutshane, zithintela umlilo onokubakho, ukubetheka kombane, kunye nomonakalo kwizixhobo kunye neentambo. Ukongeza, iziphuli zesekethe zenza kube lula ukulungisa ngokukhawuleza ngokuchonga iisekethe ezineengxaki ngokulula, ngaloo ndlela zenza kube lula ukusombulula iingxaki ngokukhawuleza. Ukusebenza kwayo okuthembekileyo kunciphisa ixesha lokungasebenzi, kuqinisekisa ukunikezelwa kombane okungaphazanyiswayo kwaye kunciphisa iingozi ezinxulumene neengozi zombane.
5. Phucula uye kwi-Advancedumephuli wojikelezo:
Njengoko iteknoloji iqhubela phambili, izinto zanamhlanjeiziphuli zeseketheInika ezinye iimpawu eziphucula ukhuseleko kunye nokulula kombane. Ezinye zezona zixhobo zitsha zokwaphula iisekethe ziquka i-Arc Fault Circuit Interrupters (AFCIs) kunye ne-Ground Fault Circuit Interrupters (GFCIs). I-AFCI ibona i-arcing eyingozi yomlilo kwaye ikhuba i-circuit breaker ngokuzenzekelayo ukuthintela naziphi na iingozi. I-GFCI, kwelinye icala, inika ukhuseleko kwi-electrical shock ngokunqamla umbane ngokukhawuleza xa kufunyenwe impazamo yomhlaba. Ukutyala imali kwezi zixhobo ziphambili zokwaphula iisekethe kunokuphucula kakhulu ukhuseleko kunye nokuthembeka kwenkqubo yakho yombane.
6. Isiphelo:
Iziphuli zeseketheziyinxalenye ebalulekileyo yeenkqubo zombane, zibonelela ngokhuseleko kwimithwalo enzima, ii-short circuits, kunye nezinye iingxaki zombane. Ukugcinwa rhoqo, ukuhlolwa kunye nokuhlaziywa kweendlela ezisemgangathweniiziphuli zeseketheqinisekisa ukhuseleko kunye nokusebenza kakuhle kweenkqubo zombane. Ngokubeka phambili ukhuseleko lombane, awukhuseli nje kuphela ubomi kunye nepropathi, kodwa ukwaphepha nokulungiswa okubiza kakhulu kunye nexesha lokungasebenzi. Khumbula ukuba kwiinkqubo zombane, iziphuli-sekhethi ezisebenzayo zisebenza njengabalindi abathuleyo, ziqinisekisa ukuhamba kakuhle kombane ngelixa ziphepha iingozi.
