Yintoni i-MCCB?
I-Molded case circuit breakers zizixhobo zokukhusela umbane ezenzelwe ukukhusela isiphaluka sombane ngokugqithisileyo.Oku kugqithiswa ngokugqithisileyo kunokubangelwa ngenxa yokugqithiswa okanye isiphaluka esifutshane.I-molded case circuit breakers ingasetyenziswa kuluhlu olubanzi lwee-voltages kunye ne-frequencies kunye nomda ochaziweyo ophantsi kunye ophezulu wezicwangciso zohambo oluhlengahlengiswayo.Ukongeza kwiindlela zokukhubeka, ii-MCCBs zisenokusetyenziswa njengokutshintsha kwezandla zokuqhawula uqhagamshelo kwimeko kaxakeka okanye imisebenzi yolondolozo.Ii-MCCBs zibekwe emgangathweni kwaye zivavanyelwe i-overcurrent, i-voltage surge, kunye nokukhuselwa kwempazamo ukuqinisekisa ukusebenza ngokukhuselekileyo kuzo zonke iimeko kunye nezicelo.Basebenza ngokufanelekileyo njengenguqu yokusetha kwakhona kwisekethe yombane ukukhupha amandla kunye nokunciphisa umonakalo obangelwa ukugqithiswa kwesiphaluka, impazamo yomhlaba, iisekethe ezimfutshane, okanye xa umbane udlula umda wangoku.
Usetyenziso
Ukusetyenziswa kwee-molded case circuit breakers (MCCBs) kumashishini ahlukeneyo kuye kwaguqula indlela ezisebenza ngayo iinkqubo zombane.I-MCCB yinxalenye ebalulekileyo yokuqinisekisa ukusebenza okukhuselekileyo nokusebenzayo kwesekethe.Babonelela ngokhuseleko kwi-overloads, iisekethe ezimfutshane, kunye nezinye iziphene zombane, ezibaluleke kakhulu ekuthinteleni iingozi zombane kunye neengozi zomlilo.
Enye yeenzuzo eziphambili zee-MCCBs kukukwazi kwabo ukuphatha imisinga ephezulu.Zenzelwe ngokukodwa ukukhusela nokulawula iisekethe ezineemfuno eziphezulu zamandla.Amashishini afana nemveliso, imigodi, i-oyile kunye negesi, kunye nezothutho zithembele kakhulu kwi-MCCBs ukukhusela izixhobo zabo zombane ezibalulekileyo kunye neziseko.Ukukwazi kwe-MCCBs ukuphatha ngokufanelekileyo imisinga ephezulu kwaye ngokuzenzekelayo ukuqhawula amandla xa kuthe kwenzeka ukugqithiswa okanye ukungaphumeleli kwenza ukuba ii-MCCB zibe yimfuneko kula mashishini.
Enye inzuzo ebalulekileyo ye-MCCB kukulula kwayo ukufakela kunye nokusetyenziswa.Zincinci ngobukhulu kwaye zinokudityaniswa ngokulula kwiibhodi zokutshintsha kunye neebhodi zokutshintsha.Uyilo lwabo lweemodyuli luvumela ulungelelwaniso oluguquguqukayo, lubenze baqhelane neemfuno ezahlukeneyo zokufakela.Ukongeza, ii-MCCBs zifumaneka kuluhlu olubanzi lweereyithi ezilinganisiweyo, eziqinisekisa ukuhambelana nemithwalo eyahlukeneyo yombane.Ukufakela ngokulula kunye nokusetyenziswa kwenza i-MCCBs ibe yinto ethandwayo yofakelo olutsha kunye nokubuyisela kwiinkqubo zombane ezikhoyo.
Ukuchaneka kunye nokuthembeka kwe-MCCBs kudlala indima ebalulekileyo ekuqinisekiseni ukusebenza okungaphazamisekiyo kweenkqubo zombane.Ii-MCCBs zineendlela zohambo eziphambili ezifumanisa ngokuchanekileyo kwaye ziphendule iziphene zombane.Baxhotyiswe ngeentlobo ezahlukeneyo zezivamvo kunye nezivamvo ezifana ne-thermal, imagnethi, i-elektroniki, njl. njl., ezinokuva iimeko zombane ezingaqhelekanga.Xa isiphoso sifunyenwe, i-MCCB iyahamba kwaye ngoko nangoko ikhuphe umbane, ithintela nawuphi na umonakalo.
Ii-MCCBs zikwanceda ekuphuculeni ukusebenza kakuhle kwamandla kweenkqubo zombane.Ngokukhusela ngokufanelekileyo ukusilela kombane kunye nomthwalo ogqithisiweyo, banqanda ukuveliswa kobushushu obugqithisileyo kunye nenkunkuma engadingekile yombane.Oku akunciphisi kuphela umngcipheko womonakalo wezixhobo, kodwa kwandisa ukusetyenziswa kwamandla.Ngogxininiso olukhulayo lwabantu ekugcinweni kwamandla kunye nophuhliso oluzinzileyo, ukusetyenziswa kwee-mold case circuit breakers kubalulekile ukuqinisekisa ukusebenza ngokufanelekileyo kunye nokusingqongileyo kumashishini ahlukeneyo.
Ngamafutshane, ukusetyenziswa okubanzi kweesekethe zesekethe ezibunjiweyo kuye kwaphucula kakhulu ukhuseleko, ukuthembeka kunye nokusebenza kakuhle kweenkqubo zombane kumashishini ahlukeneyo.Ukukwazi kwabo ukuphatha imisinga ephezulu, ukufakela ngokulula, ukufumanisa iimpazamo ezichanekileyo, kunye negalelo ekusebenzeni kakuhle kwamandla kubenza babe zizinto eziyimfuneko ekukhuseleni nasekulawuleni umbane.Njengoko itekhnoloji iqhubela phambili, izaphuli zesekethe ezibunjiweyo ziyaqhubeka nokuvela ukuze zihlangabezane neemfuno ezikhulayo zeenkqubo zombane zanamhlanje.Njengoko imizi-mveliso iqhubeka nokuxhomekeka ekufakeni umbane ukuze isebenze, indima ye-MCCB ekuqinisekiseni ukusebenza ngokukhuselekileyo nokusebenzayo kweesekethe iya kubaluleka ngakumbi.
