Igiciro cyo kugurisha CJMM3-125 3P 125Amp Electron Molded Case Circuit Breaker MCCB

Ibisobanuro bigufi:

CJMM3 Moulded case circuit breaker (izwi hano ku izina rya circuit breaker) ifite imiterere y’ingano nto, ubushobozi bwo gucikamo ibice byinshi, gufunga umurongo mugufi, no kurwanya gutigita. Ikwiriye imiyoboro y’amashanyarazi ifite AC 50Hz, voltage y’imikorere ifite 400V, n’amashanyarazi afite amashanyarazi agera kuri 250A no munsi yayo. Ikoreshwa mu gukwirakwiza ingufu z’amashanyarazi no kurinda imiyoboro n’ibikoresho by’amashanyarazi gutwarwa n’umutwaro mwinshi, circuit ngufi n’izindi nzitizi. Ishobora kandi gukoreshwa mu guhinduranya inshuro nyinshi mu miyoboro no gutangiza moteri gake. Moteri ishobora gushyirwaho ihagaze (ni ukuvuga, ihagaze) cyangwa itambitse (ni ukuvuga, ihagaze).

Iki gicuruzwa cyujuje ibisabwa na IEC60947-2 na GB/T14048.2 “Ibikoresho byo guhinduranya umuriro w’amashanyarazi make n’ibikoresho byo kugenzura Igice cya 2: Ibice bigabanya umuriro w’amashanyarazi”.

Ibisabwa mu gukora no gushyiraho

Ubutumburuke bw'aho igikorwa cyo gushyiraho ntiburenze metero 2000.
Ubushyuhe bw'ikirere;
Ubushyuhe bw'ikirere ntarengwa bwo hejuru ntiburenze +40°C;
Ubushyuhe bw'umwuka mu gihe cy'amasaha 24 ntiburenze +35°C;
Ubushyuhe bw'ikirere buri hasi ntabwo buri munsi ya -5°C;
Imiterere y'ikirere:
Ubushyuhe bw'ikirere ntiburenga 50% iyo ubushyuhe ntarengwa buri mu kirere ari +40°C. Bushobora kugira ubushyuhe bwinshi mu bushyuhe buri hasi. Iyo ubushyuhe buke bw'ukwezi mu kwezi kw'imvura nyinshi butarenze +25°C, ubushyuhe bw'ikirere ntiburenga +25°C. Ubushyuhe ntarengwa ni 90%, bitewe n'ihindagurika ry'ubushyuhe ku buso bw'ibicuruzwa.

Icyiciro cy'ibicuruzwa

Dukurikije ubushobozi bwo gucika kw'icyuma gihagarika urujya n'uruza rw'amashanyarazi, gigabanyijemo: ubwoko busanzwe (ubwoko bwa S); ubwoko bwa b bwo hejuru (ubwoko bwa H);
Dukurikije uburyo bwo gufunga insinga bw'icyuma gica urusobe rw'amashanyarazi: a. Gushyira insinga imbere y'ikibaho; b. Gushyira insinga inyuma y'ikibaho; c. Ubwoko bwo gucomeka; d. Ubwoko bwo gukurura;
Dukurikije uburyo bwo gukora: a. Gukoresha umukingo mu buryo butaziguye; b. Gukoresha umukingo mu guhindukira; c. Gukoresha amashanyarazi;
Dukurikije umubare w'imikingo: ibiti bibiri; ibiti bitatu; ibiti bine;
Dukurikije ibikoresho: ibyuma bitanga alarm contacts, ibyuma bitanga assistant contacts, shunt release, undervoltage release;
