Iziqhekezi zeSekethe zeSigaba esinye: Ukuphucula uKhuseleko kunye noLawulo loMbane kwiindawo zokuhlala nezoRhwebo

Iziphuli zesekethe zesigaba esinyezizinto ezibalulekileyo kwiinkqubo zombane ezenzelwe ukukhusela iisekethe kunye nezixhobo zombane kwi-overcurrent kunye nee-short circuits. Eli linyathelo lokhuseleko elibalulekileyo elinceda ekuthinteleni imililo yombane kunye nomonakalo wezixhobo. Kweli nqaku, siza kuhlola imisebenzi, iintlobo, kunye nokubaluleka kwee-single-phase circuit breakers kwiinkqubo zombane.

Imisebenzi ye-single phase circuit breaker

Umsebenzi oyintloko we-single-phase circuit breaker kukuphazamisa ukuhamba kombane kwi-circuit xa i-circuit idlula imida yokusebenza ekhuselekileyo. Xa kwenzeka i-overcurrent okanye i-short circuit breaker, i-circuit breaker iyakhubeka ngokuzenzekelayo, inqumle umbane kwi-circuit echaphazelekayo. Eli nyathelo linceda ekuthinteleni ukonakala kwezixhobo zombane kunye neentambo kwaye linciphisa umngcipheko weengozi zombane.

Iintlobo zee-single phase circuit breakers

Kukho iintlobo ezahlukeneyo zee-single-phase circuit breakers, nganye yenzelwe ukusetyenziswa okuthile kunye nomlinganiselo we-voltage. Ezona ntlobo zixhaphakileyo ziquka ii-thermal-magnetic circuit breakers, ii-residual current circuit breakers (RCCB) kunye nee-miniature circuit breakers (MCB).

1. Iziphuli zesekethe ze-thermal-magnetic: Ezi ziphuli zesekethe zifaka indlela ye-thermal-magnetic ukubonelela ngokhuseleko lwe-overcurrent kunye ne-short-circuit. Izinto ze-thermal zisabela kwi-overload, ngelixa izinto ze-magnetic zisabela kwi-short circuit, nto leyo ezenza zifaneleke kwiintlobo ngeentlobo zezicelo.

2. I-Residual Current Breaker (RCCB): I-RCCB yenzelwe ukukhusela ukuvuza okanye ukusilela komhlaba. Ijonga ibhalansi yangoku phakathi kwee-conductors eziphilayo nezingathathi cala kunye nokukhubeka xa kufunyenwe impazamo, ngaloo ndlela ithintela ukutshayiswa ngumbane kunye neengozi zomlilo.

3. I-Miniature Circuit Breaker (MCB): I-MCB incinci kwaye yenzelwe ukusetyenziswa kwiinkqubo zombane ezine-voltage ephantsi. Zibonelela ngokhuseleko olugqithisileyo kunye nolwe-short-circuit kwaye zisetyenziswa kakhulu kwiindawo zokuhlala kunye nezorhwebo.

Ukubaluleka kwee-Single Phase Circuit Breakers

Ii-circuit breakers zesigaba esinye zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kwenkqubo yombane. Nazi ezinye zezizathu ezibalulekileyo zokuba zibaluleke kangaka:

1. Khusela izixhobo zombane: Iziphuli zesekethe zikhusela izixhobo zombane kunye nezixhobo ekonakalisweni okubangelwa yi-overcurrent kunye ne-short circuit. Ngokuphazamisa ukuhamba kombane xa kuyimfuneko, zinokuphepha ukulungiswa okubizayo kunye nexesha lokungasebenzi.

2. Ukuthintela umlilo: Ukugqithisa kakhulu kwesekethe kunye ne-short circuit kunokubangela imililo yombane. Ii-circuit breakers zinceda ekunciphiseni lo mngcipheko ngokunqamla umbane ngokukhawuleza xa kukho impazamo, zithintela iingozi zomlilo ezinokubakho.

3. Ukhuseleko Lomntu: Ii-RCCB zibonelela ngokhuseleko ekutshatyalalisweni ngumbane xa kukho impazamo yomhlaba okanye ukuvuza komsinga, nto leyo ibalulekileyo ekuqinisekiseni ukhuseleko lomntu kwiindawo zokuhlala nezorhwebo.

Ngamafutshane, ii-circuit breakers zesigaba esinye ziyinxalenye ebalulekileyo yeenkqubo zombane, zibonelela ngokhuseleko olubalulekileyo kwi-overcurrent, ii-short circuits, kunye neempazamo zombane. Ukukwazi kwazo ukukhusela izixhobo zombane, ukuthintela umlilo, kunye nokuqinisekisa ukhuseleko lomntu kugxininisa ukubaluleka kwazo ekugcineni ukuthembeka kunye nokuthembeka kokufakelwa kombane. Kubalulekile ukukhetha uhlobo olufanelekileyo lwe-circuit breaker kwisicelo esithile kunye nokuqinisekisa ukugcinwa rhoqo kunye novavanyo ukuze kugcinwe ukusebenza kwayo ekukhuseleni iinkqubo zombane.
