Le circuit breaker inezibonelelo zevolumu encinci, amandla aphezulu okuqhekeka, i-short arcing (okanye i-noarcing) njl. njl., inokuxhotyiswa ngezixhobo ezifana ne-alamu contact, i-shunt release, i-assistant contact njl.njl., yimveliso efanelekileyo kumsebenzisi. I-residual current current breaker inokufakelwa ngokuthe nkqo (ukufakelwa ngokuthe nkqo) okanye ifakwe ngokuthe tye (ukufakelwa ngokuthe tye). Imveliso ihambelana nemigangatho ye-IEC60947-2 kunye ne-Gb140482

Yintoni i-MCCB?

Ii-Molded case circuit breakers zizixhobo zokukhusela umbane ezenzelwe ukukhusela i-electrical circuit kwi-current egqithisileyo. Le current egqithisileyo inokubangelwa kukugqithisa okanye i-short circuit. Ii-molded case circuit breakers zingasetyenziswa kuluhlu olubanzi lwee-voltage kunye nee-frequency ezinomda ochaziweyo osezantsi nophezulu wezicwangciso zokutshintsha ezilungisekayo. Ukongeza kwiinkqubo zokukhubeka, ii-MCCB zingasetyenziswa njengee-manual disconnecting switches xa kukho imeko engxamisekileyo okanye imisebenzi yokulungisa. Ii-MCCB zisemgangathweni kwaye zivavanyelwa i-overcurrent, i-voltage surge, kunye nokukhuselwa kwempazamo ukuqinisekisa ukusebenza ngokukhuselekileyo kuzo zonke iindawo kunye nezicelo. Zisebenza ngokufanelekileyo njenge-reset switch ye-electrical circuit ukuze zikhuphe umbane kwaye zinciphise umonakalo obangelwa yi-circuit overload, i-ground fault, i-short circuit, okanye xa i-current idlula umda we-current.

Izicelo

Ukusetyenziswa kwee-molded case circuit breakers (MCCBs) kumashishini ahlukeneyo kutshintshe indlela esebenza ngayo iinkqubo zombane. I-MCCB yinxalenye ebalulekileyo yokuqinisekisa ukusebenza ngokukhuselekileyo nangokufanelekileyo kwesekethe. Zibonelela ngokhuseleko kwiingxaki zombane ezigqithisileyo, ii-short circuits, kunye nezinye iingxaki zombane, ezibalulekileyo ekuthinteleni iingozi zombane kunye neengozi zomlilo.

Enye yezona nzuzo ziphambili zeeMCCB kukukwazi kwazo ukusingatha imisinga ephezulu. Zenzelwe ngokukodwa ukukhusela nokulawula iisekethe ezineemfuno eziphezulu zamandla. Amashishini afana nokuvelisa, ukwemba imigodi, ioyile negesi, kunye nezothutho axhomekeke kakhulu kwiiMCCB ukukhusela izixhobo zawo zombane ezibalulekileyo kunye neziseko zophuhliso. Ukukwazi kweeMCCB ukuphatha imisinga ephezulu ngokufanelekileyo kunye nokucima umbane ngokuzenzekelayo xa kukho ukuxinana okanye ukusilela kwenza iiMCCB zibe yinto ebalulekileyo kwezi shishini.

Enye inzuzo ebalulekileyo ye-MCCB kukuba kulula ukuyifaka nokusetyenziswa kwayo. Zincinci ngobukhulu kwaye zinokudityaniswa ngokulula kwii-switchboards nakwii-switchboards. Uyilo lwazo lwemodyuli luvumela uhlengahlengiso oluguquguqukayo, okwenza ukuba zilungele iimfuno ezahlukeneyo zokufakela. Ukongeza, ii-MCCBs ziyafumaneka kuluhlu olubanzi lwe-currents ezilinganisiweyo, ukuqinisekisa ukuhambelana nemithwalo eyahlukeneyo yombane. Ukulula kokufakela nokusetyenziswa kwenza ii-MCCBs zibe lukhetho oludumileyo lokufakelwa okutsha kunye nokulungiswa kwiinkqubo zombane ezikhoyo.

Ukuchaneka nokuthembeka kwee-MCCB kudlala indima ebalulekileyo ekuqinisekiseni ukusebenza okungapheliyo kweenkqubo zombane. Ii-MCCB zineendlela eziphambili zokujika ezichonga ngokuchanekileyo kwaye ziphendule kwiimpazamo zombane. Zixhotyiswe ngeentlobo ezahlukeneyo zeesensa kunye neesensa ezifana nobushushu, imagnethi, i-elektroniki, njl.njl., ezinokubona iimeko zombane ezingaqhelekanga. Nje ukuba kufunyenwe impazamo, i-MCCB iyawa kwaye iwaqhawule ngoko nangoko amandla, ithintele nawuphi na umonakalo ongaphezulu.

Ii-MCCB zikwanceda ekuphuculeni ukusebenza kakuhle kwamandla kwiinkqubo zombane. Ngokukhusela ngokufanelekileyo ukusilela kombane kunye nokugqithisa kakhulu, zithintela ukuveliswa kobushushu obugqithisileyo kunye nenkcitho engeyomfuneko yombane. Oku akunciphisi nje kuphela umngcipheko wokonakala kwezixhobo, kodwa kukwaphucula ukusetyenziswa kwamandla. Njengoko abantu begxininisa ngakumbi ekongeni amandla kunye nophuhliso oluzinzileyo, ukusetyenziswa kwee-molded case circuit breakers kubalulekile ukuqinisekisa ukusebenza okusebenzayo nokusingqongileyo kumashishini ahlukeneyo.

Ngamafutshane, ukusetyenziswa ngokubanzi kwee-molded case circuit breakers kuphucule kakhulu ukhuseleko, ukuthembeka kunye nokusebenza kakuhle kweenkqubo zombane kumashishini ahlukeneyo. Amandla azo okusingatha imisinga ephezulu, ukulula kokufakela, ukufunyanwa kweempazamo ngokuchanekileyo, kunye negalelo ekusebenzeni kakuhle kwamandla kuzenza zibe zizinto ezibalulekileyo ekukhuseleni nasekulawuleni umbane. Njengoko iteknoloji iqhubela phambili, ii-molded case circuit breakers ziyaqhubeka nokukhula ukuze zihlangabezane neemfuno ezikhulayo zeenkqubo zombane zanamhlanje. Njengoko amashishini eqhubeka nokuxhomekeka kumbane ukuze asebenze, indima ye-MCCB ekuqinisekiseni ukusebenza ngokukhuselekileyo nangokufanelekileyo kwee-circuits iya kuba yinto ebaluleke ngakumbi.
