Ama-Molded case circuit breakers (MCCB)

Ama-circuit breaker e-Molded Case (I-MCCB) zidlala indima ebalulekile ekuvikeleni izinhlelo zikagesi ekugcwaleni ngokweqile, emonakalweni we-short circuit kanye ne-undervoltage. I-CMTM1 series MCCB ingenye ye-MCCB enjalo evelele ngokwethenjelwa nokusebenza kahle. Le case build case circuit breaker inesakhiwo esincane, usayizi omncane kanye nomthamo wokuphuka ophezulu, okwenza kube ukukhetha kokuqala kwezakhiwo zezimboni nezentengiselwano.

Esinye sezici eziyinhloko zama-CMTM1 series molded case circuit breakers ububanzi bawo bokusetshenziswa. Isebenza ku-voltage elinganisiwe yokushisa engu-400/415/660/690/800/1000V, imvamisa ye-AC engu-50/60Hz. Ngaphezu kwalokho, iklanyelwe ukuphatha ama-voltage alinganisiwe angu-690V nangaphansi. Lokhu kuguquguquka kwenza ifaneleke ukusetshenziswa ezinhlelweni ezahlukene zikagesi, okuqinisekisa ukuvikelwa okusebenzayo nokuthembekile.

I-CMTM1 MCCB incane futhi ingafakwa kalula ezindaweni ezinesikhala esincane. Ubuncane bayo buyenza ibe yindawo ekahle yokusetshenziswa kuma-switchboard kanye nama-switchgear assemblies lapho yonke indawo ibalulekile khona. Naphezu komklamo wayo omncane, le MCCB inamandla amakhulu okuphula, ikwazi ukuphazamisa ama-short circuits nokuvikela imishini exhunyiwe.

Esinye sezici ezivelele ze-CMTM1 MCCB yi-short arc yayo. Uma kwenzeka i-short circuit, i-MCCB iyicisha ngokushesha i-arc, inciphise umonakalo ongaba khona. Lesi sici sinciphisa kakhulu isikhathi sokungasebenzi futhi siqinisekisa ukuqhubeka kwebhizinisi, okwenza kube yimpahla ebalulekile ezimbonini lapho ukunikezwa kwamandla okungaphazamiseki kubalulekile khona.

I-CMTM1 MCCB iza nohlu oluphelele lwezesekeli zangaphakathi nezangaphandle, okwenza kube lula ukuzenza ngokwezifiso nokuhlanganiswa nezinhlelo ezahlukene zikagesi. Lezi zesekeli zithuthukisa ukusebenza nokusebenza kwe-MCCB, okuvumela ukuthi ivumelane nezidingo ezithile futhi iqinisekise ukuvikelwa okuhle kwemigqa nemishini kagesi.

Ngaphezu kwalokho, i-CMTM1 molded case circuit breaker ihambisana nezindinganiso ezibekwe yi-IEC60947-2 ukuqinisekisa ikhwalithi nokuphepha. Le zindinganiso iyaqashelwa emhlabeni wonke futhi iqinisekisa ukuthi imikhiqizo ihlangabezana nezidingo ezidingekayo zezinhlelo zikagesi. Ngokuhambisana nale zindinganiso, abasebenzisi bangaqiniseka ngokwazi ukuthi izinhlelo zabo zikagesi zivikelwe yi-MCCBs ethembekile nesezingeni eliphezulu.

Sekukonke, i-CMTM1 series molded case circuit breaker iwumkhiqizo omuhle kakhulu ohlinzeka ngokuvikelwa okuhle kakhulu kwezinhlelo zikagesi. Inesakhiwo esincane, usayizi omncane, amandla aphezulu okuphuka, i-arc emfushane, izesekeli zangaphakathi nezangaphandle eziphelele, futhi yenzelwe ukuhlangabezana nezidingo zezimboni ezahlukene. Ine-overload, i-short circuit, ukuvikelwa kwe-undervoltage kanye neminye imisebenzi yokuvikela imigqa kanye nemishini yokunikeza ugesi ekulimaleni. Ngaphezu kwalokho, ihambisana nezindinganiso ze-IEC60947-2, iqinisekisa ukuthembeka kwayo kanye nokuhambisana nemithetho yokuphepha yomhlaba wonke. I-CMTM1 MCCB iyisinqumo sokuqala samabhizinisi nezimboni ezihlonipha ukuvikelwa kukagesi okusebenzayo nokuthembekile.
