Ukuba i-circuit breaker yakho iyaqhubeka nokukhubeka, kufuneka uyiqalise kwakhona. Ukuze uyiqalise kwakhona, cima i-circuit breaker ngokushukumisa iswitshi, uze uyivule kwakhona. Ukuze ukhuseleke, gcina umgama okhuselekileyo ukusuka kwiphaneli ukuze uthintele naziphi na iintlantsi, okanye unxibe iiglasi zokhuseleko. Ngaphambi kokuba ukhulule kwaye ufake izixhobo, buyisela kwakhona i-circuit breaker ukuze ufumane unobangela wohambo.

Nangona ii-stripped circuit breakers ziqinisekisa ukhuseleko, kunokuba yinto ecaphukisayo ukuzifumana rhoqo kwaye uziphinde uzidibanise kwakhona.

Kutheni i-circuit breaker yam iqhubeka nokukhubeka?

Ukuba i-circuit breaker yakho ikhubeka rhoqo, kukho ingxaki nge-circuit. Esinye sezixhobo zakho sinokuba ne-short circuit okanye i-ground failure. Kusenokuba neempawu zokuba i-circuit igcwele kakhulu okanye ibhokisi ye-breaker ine-wrong. Hlala ujonge zonke ezi zizathu ezinokubangela ukuba i-circuit breaker yakho ikhubeke rhoqo.

Ukuba uyazi isizathu sokukhubeka rhoqo, kukho izinto ezimbalwa onokuzenza. Makhe sijonge izizathu ezihlanu eziphambili ezibangela ukuba abaphuli besekethe bakhubeke.

1. Ukugqithisa kakhulu kwesekethe

Ukuxinana kweesekethe sesinye sezizathu eziphambili zokuba ii-circuit breakers zikhubeke rhoqo. Oku kwenzeka xa ufuna isekethe ethile inike amandla angaphezu kwalawo inawo ngokwenene. Oku kuya kubangela ukuba isekethe ifudumale kakhulu, nto leyo ebeka zonke izixhobo eziqhagamshelwe kwisekethe emngciphekweni.

Umzekelo, ukuba iTV yakho iqhagamshelwe kwisekethe efuna ii-amps ezili-15 kodwa ngoku isebenzisa ii-amps ezingama-20, iisekethe zenkqubo yeTV ziya kutshiswa zonakale. Ii-circuit breakers ziyakhubeka ukuthintela oku ukuba kungenzeki, mhlawumbi nomlilo omkhulu.

Ungayilungisa le nto ngokuzama ukusasaza izixhobo zakho zombane kwakhona uze uzigcine kude neesekethe ezifanayo nezinconywa ngabalungisi bombane. Ungacima nezinye izixhobo ukuze unciphise umthwalo wombane kwi-circuit breaker.

2. Isekethe emfutshane

Esinye isizathu esiqhelekileyo sokukhubeka kwe-circuit breaker yi-short circuit, eyingozi ngakumbi kune-overloaded circuit. I-short circuit yenzeka xa i-“hot” wire idibana ne-“neutral” wire kwenye yee-electrical outlet zakho. Nanini na xa oku kusenzeka, uninzi lwamandla luhamba kwi-circuit, nto leyo edala ubushushu obungaphezulu kunobo i-circuit enokubuthwala. Xa oku kusenzeka, i-circuit breaker iya kuqhubeka nokukhubeka, ivala i-circuit ukuthintela isiganeko esiyingozi njengomlilo.

Iisekethe ezimfutshane zinokwenzeka ngenxa yezizathu ezininzi, ezinje ngentambo engalunganga okanye uqhagamshelo olukhululekileyo. Ungayibona isekethe emfutshane ngevumba elivuthayo elihlala lijikeleze i-breaker. Ukongeza, ungabona nombala omdaka okanye omnyama ojikeleze yona.

3. Ukunyuka kwesiphako somhlaba

Ukunyuka kwesiphako somhlaba kufana ne-short circuit. Oku kwenzeka xa i-hot wire ichukumisa i-ground wire eyenziwe ngobhedu olungenanto okanye ecaleni kwebhokisi yesokhethi yesinyithi eqhagamshelwe kwi-ground wire. Oku kuya kubangela ukuba kubekho umbane omninzi ohamba kuyo, nto leyo i-circuit engenakuyiphatha. I-circuit breaker iyahamba ukuze ikhusele ii-circuits kunye nezixhobo ekutshiseni kakhulu okanye emlilweni onokubakho.

Ukuba kukho umonakalo omkhulu emhlabeni, ungazichonga ngokutshintsha kombala ojikeleze iplagi.

4. Iziphuli zesekethe ezineempazamo

Ukuba akukho nanye kwezi zinto zingasentla ebangela ukuba i-circuit breaker ikhubeke, i-circuit breaker yakho isenokuba nephutha. Xa i-circuit breaker indala kakhulu ukuba ingavelisa umbane, lixesha lokuyitshintsha. Kwaye, ukuba ayigcinwanga, ngokuqinisekileyo iya kuguga.

Ukuba i-breaker yakho yonakele, usenokuba nevumba lokutsha, ukhubeke rhoqo, ungaphindi uqalise ukusebenza, okanye ube neempawu zokutsha kwibhokisi ye-breaker.

5. Impazamo ye-Arc

Ngokubanzi, iimpazamo ze-arc zithathwa njengezona zibangela ukukhubeka rhoqo kwee-circuit breakers. Impazamo ye-arc yenzeka xa ucingo olukhululekileyo okanye oludlamkileyo ludala unxibelelwano olufutshane olubangela i-arcing okanye i-spark. Oku kuvelisa ubushushu kwaye kunokubangela umlilo wombane. Ukuba uva iswitshi yesibane esitshoyo okanye isandi sokuvungama esivela kwindawo yokukhupha, unempazamo ye-arc.

Ukuba uyayiphepha okanye ungayinaki nayiphi na kwezi ngxaki, ubeka ukhuseleko losapho lwakho kunye nabantu obathandayo emngciphekweni omkhulu. Ukuba ufumana uhambo oluqhelekileyo lokuchitha iisekethe, lixesha lokuba ubize ingcali ukuze iphande ingxaki. Musa ukuzama ukuyisingatha ngokwakho le nto.
