Ibipimo kuri MCB bihagarariye iki?

Utwuma duto tw'amashanyarazi (MCB) zikoreshwa cyane cyane mu kurinda imiyoboro y'amashanyarazi ku miyoboro migufi n'ibintu byinshi biremereye, kandi zishobora no gukoreshwa mu buryo bwo gukwirakwiza ingufu z'amashanyarazi ku matara cyangwa moteri.
Irangwa n'ubwiza n'isura nto, uburemere bworoshye, imikorere myiza kandi yizewe, ubushobozi bwo kumenagura cyane, kugwa vuba, gushyiraho byoroshye inzira zo kuyobora no kumara igihe kirekire.
Hari ibimenyetso byinshi kuri miniature circuit breaker (MCB). Bisobanura iki?

1. “C20” bisobanura iki?
20 ni wo muyoboro w’amashanyarazi ufite amanota, none se C bivuze iki? C ihagarariye imiterere y’agace gatanga amashanyarazi gahita gatera, gagabanyijemo ubwoko bwa B, C na D;
Ubwoko bwa B (3-5) In bugwa inshuro 3 kugeza kuri 5 z'umuvuduko w'amashanyarazi. Bukwiriye imitwaro irwanya gusa n'imirongo y'amatara idakoresha imbaraga nyinshi. Ubu bwoko bw'umutwaro bufite umuvuduko muto wo gutangira kandi bukunze gukoreshwa mu matara yo mu rugo cyangwa ahantu hakenewe uburinzi bwinshi.
Ubwoko bwa C (5-10) In bugwa inshuro 5 kugeza ku 10 z'umuvuduko w'amashanyarazi. Bukwiriye imitwaro ikoreshwa mu gukurura no gukoresha amatara afite ubukana bwinshi, nka amatara ya tungsten halogen. Imiterere yayo yo gutangira ifite agaciro kanini k'umuvuduko w'amashanyarazi kandi muri rusange ikoreshwa mu kurinda imiyoboro y'amashanyarazi. n'imibare y'amatara ifite umuvuduko w'amashanyarazi usanzwe.
Ubwoko bwa D (10-14) In igwa inshuro 10 kugeza kuri 14 z'umuvuduko w'amashanyarazi. Ikwiriye sisitemu zo gukwirakwiza ingufu zifite imitwaro myinshi y'amashanyarazi n'imivuduko minini y'amashanyarazi, nka moteri, valve za solenoid n'indi mitwaro. Iyo mitwaro ifite imitwaro myinshi y'amashanyarazi.

2.240V/400V 50Hz/60Hz bivuga imiyoboro ikoreshwa;
3.IEC60898 yerekeza ku gipimo mpuzamahanga cya tekiniki y'amashanyarazi IEC60898.
4. Ni iki 4500A iri hepfo isobanura? Ni umuriro w'amashanyarazi?
Mu by’ukuri ni umuriro w’amashanyarazi, bivuze ko ari wo mutekano ntarengwa wo kugabanya ingufu. Ni ukuvuga ko iyo umurongo ufunguye, niba umuriro urenze 3000A, ushobora kudacika. Iyi parametre iratandukanye ku bakora ibikoresho bitandukanye.

5. Iki kimenyetso bivuze iki?
Iki kimenyetso kigaragaza ko icyuma gihagarika urujya n'uruza gifite imikorere ibiri yo kurinda umuvuduko mwinshi n'umuvuduko mugufi.
