Miniature Circuit Breaker Ibikoresho byongera umutekano nibikorwa

Imikoranire y'abafasha (OF) ikora nk'ibipimo by'ingenzi kandi bigenzura. Muburyo bwahujwe na MCB'imikorere yimikorere, batanga ibimenyetso byamashanyarazi byizewe byerekana imiterere yamenetse (OFF) cyangwa ifunze (ON). Aya makuru ni ntangarugero kubikoresho byo kurebera kure, sisitemu ya SCADA, cyangwa imiyoboro ihuza imiyoboro, bituma abashoramari bemeza imiterere yumuzunguruko batabanje kugenzura umubiri. Ihuriro ryemeza neza ko kugenzura bikurikiranye nu mwanya wacitse bikorwa neza kandi neza.

Muri ubwo buryo, Imenyekanisha (SD) ritanga imenyesha ryibintu byihariye. Ikora yigenga itumanaho ryabafasha, mubisanzwe ihindura leta gusa iyo Umucyo muto ingendo mu buryo bwikora bitewe nuburemere burenze cyangwa bugufi bwumuzunguruko. Iki kimenyetso gitandukanye ningirakamaro muguhita umenya amakosa, gukurura impuruza, cyangwa sisitemu yo gutema ibiti kugirango umenyeshe abakozi bashinzwe kubungabunga ko guhagarika byikora byabayeho, bigatuma igisubizo cyihuta kandi kigabanya igihe cyo gutaha. Iyuzuza imikorere yibanze yo kurinda hamwe namakuru yingirakamaro yo gusuzuma.

Urugendo rwa Shunt (MX) rutangiza ubushobozi bukomeye bwo kugenzura. Iki gikoresho gikoreshwa na solenoid cyemerera the Umucyo muto gukingurwa (gukandagira) kure ukoresheje ikimenyetso cyamashanyarazi, utitaye kubihari birenze urugero cyangwa bigufi. Ibi nibyingenzi mugushira mubikorwa ibikorwa byo guhagarika byihutirwa, sisitemu yo gutabaza umuriro (aho imiyoboro ikenera de-ingufu byihuse), cyangwa guhagarika kure kubikorwa byo kubungabunga. Igice cya MX gitanga urwego rukomeye rwo kugenzura imikorere no gutabara umutekano.

Ibikoresho bya OF (Auxiliary Contact), SD (Alarm Contact), na MX (Urugendo rwa Shunt) bizamura cyane ibikorwa byumutekano n'umutekano bya MCBs zisanzwe. Mu koroshya imiterere ya kure ikurikirana, gutanga amakosa yerekana ako kanya, no gufasha gutembera kure, bahindura ibyingenzi Umucyo muto mubice byinshi byubwenge kandi byitabira muri sisitemu y'amashanyarazi igoye. Kwishyira hamwe kwabo bituma sisitemu y'amashanyarazi idakora neza gusa ahubwo ifite umutekano muke no kugenzura cyane, kugabanya ingaruka ziterwa numutwaro urenze urugero, imiyoboro migufi, hamwe ningaruka zikorwa mubikorwa bitandukanye.
