Isicelo

I-CJMM1 series molded case circuit breaker (ebizwa ngokuba yi-circuit breaker) iyasebenza kwi-AC 50/60HZ power distribution network circuit ene-insulation voltage elinganisiweyo ye-800V, i-voltage yokusebenza elinganisiweyo ye-690V kunye ne-operation current elinganisiweyo ukusuka kwi-10A ukuya kwi-630A, isetyenziselwa ukusasaza amandla kunye nokuthintela izixhobo zesekethe kunye nombane ukuba zingamonakalisi ngenxa yokugqithiswa kakhulu, i-short circuit, i-under voltage kunye nezinye iimpazamo, ikwasetyenziselwa ukuqala rhoqo kwe-motor kunye nokugqithiswa kakhulu, i-short circuit kunye nokukhuselwa kwe-under voltage. 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

Iimpawu zeIiMCCB

IiMCCBZenzelwe imisebenzi eliqela enceda ekukhuseleni iinkqubo zombane ngendlela ekhuselekileyo nethembekileyo. Ezinye zeempawu eziphambili ze-MCCB ziquka:

Umthamo ophezulu wokuqhekeza:Abaphuli beesekethe zetyala elibunjiweyoziyakwazi ukwaphula imitha yamandla ukuya kuthi ga kumawaka ee-ampere, nto leyo ezenza zibe zilungele ukusetyenziswa kwamandla aphezulu.
Indlela yokujikeleza ngemagnethi eshushu: Ii-molded case circuit breakers zisebenzisa indlela yokujikeleza ngemagnethi eshushu ukuze zibone kwaye ziphendule kwi-overcurrent kunye ne-short circuits. Ii-thermal trip elements zisabela kwi-overloads, ngelixa ii-magnetic trip elements zisabela kwi-short circuits.
Ulungiselelo lohambo oluhlengahlengiswayo: Ii-MCCB zinelungiselelo lohambo oluhlengahlengiswayo, oluvumela ukuba zibekwe kwinqanaba elifanelekileyo lesicelo esifunekayo.
Uluhlu olubanzi lobukhulu besakhelo: Ii-MCCB ziyafumaneka ngobukhulu besakhelo obahlukeneyo, nto leyo evumela ukuba zisetyenziswe kwiindlela ezahlukeneyo zokusebenza. Umgaqo wokusebenza we-molded case circuit breaker Umgaqo wokusebenza we-MCCB usekelwe kwindlela yokutshiza nge-thermal-magnetic. I-thermal trip element iyaziva ubushushu obuveliswa kukuhamba kombane kwisekethe kwaye iyatshiza i-circuit breaker xa umbane udlula umlinganiselo wohambo. I-magnetic trip element iyaziva intsimi ye-magnetic eveliswa yi-short circuit kwisekethe, itshiza i-circuit breaker phantse kwangoko. Ulwakhiwo lwe-molded case circuit breaker
I-MCCB inendlu yeplastiki ebunjiweyo egcina indlela yokuhamba, izixhobo zokunxibelelana kunye nezixhobo zokuthwala umbane.
Ezi contacts zenziwe ngezinto eziqhuba kakhulu ezifana ne copper, ngelixa indlela yokuhamba ine bimetallic strip kunye ne magnetic coil.
