Iziphuli zesekethe zetyala ezibunjiweyo (MCCB)

Abaphuli beesekethe zetyala elibunjiweyo (I-MCCB) zidlala indima ebalulekileyo ekukhuseleni iinkqubo zombane ekugqithiseni kakhulu, kwi-short circuit kunye nomonakalo we-undervoltage. I-CMTM1 series MCCB yenye ye-MCCB enjalo ebalaseleyo ngokweenkcukacha zokuthembeka nokusebenza kakuhle. Le kheyisi yekheyisi ebunjiweyo inesakhiwo esincinci, incinci kwaye inomthamo ophezulu wokuqhekeka, nto leyo eyenza ukuba ibe lolona khetho luphambili kwizakhiwo zoshishino nezorhwebo.

Enye yezona zinto ziphambili ze-CMTM1 series molded case circuit breakers luluhlu olubanzi lwezicelo zazo. Isebenza kwi-rated insulation voltage 400/415/660/690/800/1000V, i-AC frequency 50/60Hz. Ukongeza, yenzelwe ukuphatha i-rated voltages ye-690V nangaphantsi. Olu tshintsho lwenza ukuba ifaneleke ukusetyenziswa kwiinkqubo ezahlukeneyo zombane, iqinisekisa ukhuseleko olusebenzayo noluthembekileyo.

I-CMTM1 MCCB incinci kwaye inokufakelwa lula kwiindawo ezinesithuba esincinci. Ubungakanani bayo obuncinci buyenza ifaneleke ukusetyenziswa kwiindawo zokudibanisa ii-switchboard kunye nee-switchgear apho yonke indawo ibalulekile. Nangona iyilwe kancinci, le MCCB inomthamo ophezulu wokuqhekeza, ikwazi ukuphazamisa ii-short circuits kwaye ikhusele izixhobo ezixhunyiweyo.

Enye yezona mpawu zibalaseleyo ze-CMTM1 MCCB yi-short arc yayo. Xa kwenzeka i-short circuit, i-MCCB iyicima ngokukhawuleza i-arc, inciphisa umonakalo onokubakho. Olu phawu lunciphisa kakhulu ixesha lokungasebenzi kwaye luqinisekisa ukuqhubeka kweshishini, nto leyo eyenza ukuba ibe yimpahla ebalulekileyo kumashishini apho ukunikezelwa kombane okungaphazanyiswayo kubalulekile.

I-CMTM1 MCCB ikwaza noluhlu olupheleleyo lwezixhobo zangaphakathi nezangaphandle, okwenza kube lula ukuziqhelanisa nokuzidibanisa kwiinkqubo ezahlukeneyo zombane. Ezi zixhobo ziphucula ukusebenza kunye nokusebenza kwe-MCCB, zivumela ukuba ilungelelaniswe neemfuno ezithile kwaye iqinisekise ukhuseleko olufanelekileyo lwemigca kunye nezixhobo zamandla.

Ukongeza, i-CMTM1 molded case circuit breaker ihambelana nemigangatho ebekwe yi-IEC60947-2 ukuqinisekisa umgangatho nokhuseleko. Lo mgangatho uyaziwa kwihlabathi liphela kwaye uqinisekisa ukuba iimveliso ziyahlangabezana neemfuno ezifunekayo kwiinkqubo zombane. Ngokuthobela lo mgangatho, abasebenzisi banokuqiniseka ukuba iinkqubo zabo zombane zikhuselwe zii-MCCB ezithembekileyo nezisemgangathweni ophezulu.

Lilonke, i-CMTM1 series molded case circuit breaker yimveliso ebalaseleyo ebonelela ngokhuseleko olugqwesileyo kwiinkqubo zombane. Inesakhiwo esincinci, ubungakanani obuncinci, amandla aphezulu okuqhekeza, i-arc emfutshane, izixhobo zangaphakathi nezangaphandle ezipheleleyo, kwaye yenzelwe ukuhlangabezana neemfuno zamashishini ahlukeneyo. Ine-overload, i-short circuit, ukhuseleko lwe-undervoltage kunye neminye imisebenzi yokukhusela imigca kunye nezixhobo zombane ekonakalisweni. Ukongeza, ihambelana nemigangatho ye-IEC60947-2, iqinisekisa ukuthembeka kwayo kunye nokuthobela imigaqo yokhuseleko yehlabathi. I-CMTM1 MCCB lukhetho lokuqala kumashishini nakumashishini axabisa ukhuseleko lombane olusebenzayo noluthembekileyo.
