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

IZIQHEKEZO ZESIPHAKELE ESIBUMBILEYO (MCCB)

Ii-Molded case circuit breakers zizixhobo zokukhusela umbane ezenzelwe ukukhusela i-electrical circuit kwi-current egqithisileyo. Le current egqithisileyo inokubangelwa kukugqithisa okanye i-short circuit. Ii-molded case circuit breakers zingasetyenziswa kuluhlu olubanzi lwee-voltage kunye nee-frequency ezinomda ochaziweyo osezantsi nophezulu wezicwangciso zokutshintsha ezilungisekayo. Ukongeza kwiinkqubo zokukhubeka, ii-MCCB zingasetyenziswa njengee-manual disconnecting switches xa kukho imeko engxamisekileyo okanye imisebenzi yokulungisa. Ii-MCCB zisemgangathweni kwaye zivavanyelwa i-overcurrent, i-voltage surge, kunye nokukhuselwa kwempazamo ukuqinisekisa ukusebenza ngokukhuselekileyo kuzo zonke iindawo kunye nezicelo. Zisebenza ngokufanelekileyo njenge-reset switch ye-electrical circuit ukuze zikhuphe umbane kwaye zinciphise umonakalo obangelwa yi-circuit overload, i-ground fault, i-short circuit, okanye xa i-current idlula umda we-current.

Imodeli yeMveliso

CJ: Ikhowudi yeshishini
M: Isixhobo sokwaphula isekethe esibunjiweyo
1: Inombolo yoYilo
□:Umlinganiselo wangoku wesakhelo
□:Umthamo wokuphuka uphawu lwekhowudi/S lubonisa uhlobo oluqhelekileyo (u-S unokushiywa) u-H ubonisa uhlobo oluphezulu

Qaphela: Kukho iintlobo ezine ze-neutral pole (i-N pole) kwimveliso yezigaba ezine. I-neutral pole yohlobo A ayinayo i-over-current tripping element, ihlala ivuliwe, kwaye ayivulwa okanye icinywe kunye nezinye iipali ezintathu.
Ipali engathathi cala yohlobo B ayinayo into yokukhuhla ngamandla angaphezu kombane, kwaye ivulwa okanye icinywe kunye nezinye iipali ezintathu (ipali engathathi cala ivulwa ngaphambi kokuba icinywe) Ipali engathathi cala yohlobo C inento yokukhuhla ngamandla angaphezu kombane, kwaye ivulwa okanye icinywe kunye nezinye iipali ezintathu (ipali engathathi cala ivulwa ngaphambi kokuba icinywe) Ipali engathathi cala yohlobo D inento yokukhuhla ngamandla angaphezu kombane, ihlala ivulwa kwaye ayivulwa okanye icinywe kunye nezinye iipali ezintathu.
