Nika ingqalelo efanayo kukhuseleko kunye nokuthembeka: Ukutolikwa kweempawu eziphambili zee-molded case circuit breakers

I-Molded Case Circuit Breaker (MCCB)yinxalenye ebalulekileyo yenkqubo yokusasazwa kombane. Yenzelwe ukukhusela ukufakelwa kombane kunye nabasebenzi kwiingozi ezinokubakho ezibangelwa ziisekethe ezimfutshane, ukugqithisa kunye nezinye iimpazamo zombane. Ngenxa yokuthembeka nokusebenza kwayo,I-MCCBisetyenziswa kakhulu kwizakhiwo zorhwebo, zoshishino, kunye neendawo zokuhlala.

Enye yezona nzuzo ziphambili zeI-MCCByikhono layo lokuphazamisa ukuhamba kombane ngexesha leempazamo. Xa kwenzeka i-short circuit okanye i-overload,I-MCCBikhawuleza ibone ukuhamba kombane okungaqhelekanga kwaye ivule iindawo ezidibanayo, ikwazi ukwahlula isekethe enengxaki kuyo yonke indawo efakelweyo. Le mpendulo ikhawulezayo inceda ekuthinteleni ubushushu obugqithisileyo kunye nemililo enokubakho, igcina isakhiwo kunye nabantu abahlala kuso bekhuselekile.

IiMCCBZiyaziwa nangokwakhiwa kwazo okuqinileyo, okuzivumela ukuba zikwazi ukumelana nemisinga ephezulu. Ezi zixhobo zokwaphula iisekethe zihlala zenziwe ngezinto ezihlala ixesha elide, ezifana neendlu ezibunjiweyo, kwaye zenzelwe ukusingatha imithwalo eyahlukeneyo yombane. Ziyakwazi ukumelana nemisinga ephezulu yesekethe emfutshane kwaye zibonelele ngokhuseleko oluthembekileyo nakwiindawo zombane ezinzima.

Ukongeza,I-MCCBInika ezinye iimpawu zokuphucula ukusebenza kwayo kunye nokuguquguquka. UninziIiMCCBziquka useto lohambo oluhlengahlengiswayo, oluvumela umsebenzisi ukuba enze ngokwezifiso impendulo ye-circuit breaker kwimithwalo ethile yombane. Olu phawu luluncedo ngakumbi kwizicelo ezifuna amanqanaba ahlukeneyo angoku, njengakwiindawo zoshishino ezineemishini ezahlukeneyo.

Ukongeza,IiMCCBidla ngokuba neendlela zokukhusela ezakhelwe ngaphakathi ezifana nokukhubeka kobushushu kunye nemagnethi. I-thermal tripper ikhusela ekugqithiseni kakhulu ngokubona ubushushu obugqithisileyo, ngelixa i-magnetic tripper isabela kwi-short circuit ngokubona ukunyuka ngequbuliso kombane. Ezi layers zininzi zokhuseleko ziqinisekisa ukuba i-MCCB isabela ngokukhawuleza kwiimpazamo ezahlukeneyo zombane, inciphisa umonakalo kunye nexesha lokungasebenzi.

Isishwankathelo,abaphuli beesekethe zetyala elibunjiweyozizinto ezibalulekileyo kwiinkqubo zokusasazwa kwamandla. Ukukwazi kwayo ukubona nokusabela kwiimeko zangoku ezingaqhelekanga, kunye nolwakhiwo lwayo oluhlala ixesha elide kunye neempawu ezongezelelweyo, kuyenza ibe sisixhobo esibalulekileyo sokuqinisekisa ukhuseleko lombane kwiindlela ezahlukeneyo zokusebenza. Nokuba kukwizakhiwo zorhwebo, zoshishino okanye zokuhlala,IiMCCBukubonelela ngokhuseleko oluthembekileyo nolusebenzayo lweziphene zombane ukukhusela izixhobo kunye nabasebenzi.
