I-Miniature Circuit Breaker (MCB) kunye noKhuseleko oluPhezulu kunye noYilo lweModyuli

I-Miniature Circuit Breaker (MCB) sisixhobo esithembekileyo kunye nesicwebileyo sokukhusela umbane esilungiselelwe ukukhusela iisekethe zakho zombane kwii-overcurrents, iisekethe ezimfutshane, kunye nokugqithiswa. Ngoluhlu olubanzi lwemisinga ekalisiweyo kunye noyilo lwemodyuli, le MCB ifanelekile kwindawo yokuhlala, yorhwebo, kunye nezicelo zoshishino. Nangona ingabandakanyi ukukhuselwa kwangoku okuvuzayo, ukugxila kwayo kukhuseleko olugqithisiweyo luqinisekisa ukusebenza okuqinileyo kunye nokuqina kweenkqubo zakho zombane.

Ii-circuit breakers zethu ezincinci (MCBs) zisetyenziswa kwiimeko ezahlukeneyo. Kwizicelo zokuhlala, zikhusela ngokufanelekileyo iisekethe zendlu, ziqinisekisa ukuba izixhobo kunye neengcingo zikhuselwe kwi-overcurrent and short circuits. Kwiindawo zorhwebo, ii-MCBs zikhusela izixhobo zeofisi, iinkqubo zokukhanyisa, kunye nezinye izixhobo zombane, ziqinisekisa ukusebenza kwazo ngokukhuselekileyo. Kwiimeko zoshishino, zibonelela ngokhuseleko oluthembekileyo olugqithisiweyo kumatshini kunye neenkqubo zombane ezinzima. Ii-MCBs zikwasetyenziswa kwiinkqubo zamandla avuselelekayo, ukuqinisekisa ukhuseleko lweepaneli zelanga kunye nezinye izibonelelo zamandla avuselelekayo.

Umsebenzi wokhuseleko ogqithisiweyo weMCBinokuthintela ngokufanelekileyo umonakalo obangelwa yisekethe emfutshane kunye nokugqithisa, ukuqinisekisa ukhuseleko lweenkqubo zombane. Uluhlu lwayo olubanzi lwee-currents ezilinganisiweyo, ezibandakanya i-6A, i-10A, i-16A, i-20A kunye ne-32A, ifanelekile kwizicelo ezahlukeneyo kunye neemfuno zomthwalo. Uyilo oludibeneyo kunye nemodyuli lwenza ufakelo kunye nokutshintshwa kube lula, olulungele kakhulu iibhodi zokutshintsha zanamhlanje ezinendawo encinci. I-MCB eyenziwe ngezinto ezikumgangatho ophezulu iqinisekisa ukuhlala kwayo kunye nokuthembeka kwiindawo ezinzima. Ukubonelela ngokukhuselwa okufunekayo kwi-overcurrent kwixabiso elifikelelekayo kwenza kube yinto efikelelekayo yokuzikhethela kuluhlu olubanzi lwabasebenzisi.

MCBinemisebenzi yokukhusela i-overcurrent kunye ne-short-circuit, enokuthi ikhuphe ngokuzenzekelayo isiphaluka xa i-overcurrent okanye i-short circuit iyenzeka, ngaloo ndlela ikhusela umonakalo kwizixhobo kunye neengcingo. Uluhlu lwalo olubanzi lwangoku luxhasa iindidi ezilinganisiweyo, ezifanelekileyo kwimimiselo eyahlukeneyo yombane. Uyilo lweemodyuli lwenza i-MCB icwecwe kwaye kulula ukuyifaka, ihambelana neebhodi zokuhambisa eziqhelekileyo. Ugxininiso ekukhuselweni kwe-overcurrent, le mveliso ifanelekile kwizicelo ezingadingi ukukhuselwa kokuvuza. Umthamo ophezulu wokuphulwa uqinisekisa ukusebenza kwayo okuthembekileyo kwiimeko ezinzima.

MCBithobela imigangatho yokhuseleko yehlabathi efana ne-IEC 60898, iqinisekisa umgangatho wayo ophezulu kunye nokusebenza okuthembekileyo. Esi satifikethi asiphuculi kuphela ukuthembeka kwemveliso, kodwa sikwabonelela abasebenzisi ngokhuseleko olongezelelweyo. Abasebenzisi banokuyisebenzisa ngokuzithemba kwaye banandiphe ukhuseleko oluzisayo.

MCBiyilwe ngendlela elula yokuvula/yokucima, elungele abasebenzisi ukulawula ngesandla kunye nokusetha ngokutsha emva kokukhubeka. Nokuba kusekhaya, kwiofisi okanye kumaziko oshishino, kulula kakhulu ukusebenza. Izaphuli zethu zesekethe ezincinci ziyilelwe ukubonelela ngokhuseleko oluthembekileyo nolusebenzayo kwizicelo ezahlukeneyo ukuhlangabezana neemfuno zokhuseleko zombane zabasebenzisi..
