MCCB (Molded Case Circuit Breaker) ni iki?

Ni ikiMCCB (Ikimashini gikoresha urukiramende rwa molded case)

Umutekano ni ingenzi cyane mu bijyanye n'ikoranabuhanga ry'amashanyarazi. Kugira ngo urebe ko sisitemu z'amashanyarazi zirindwa kandi wirinde kwangirika, ni ngombwa gukoresha utumashini twizewe two gufunga imiyoboro y'amashanyarazi. Mu bwoko butandukanye buhari, harimoimashini igabanya urujya n'uruza rw'amasasu (MCCB)Igaragara nk'igice cy'ingenzi. Intego y'iyi nkuru ni ukuganira ku bisobanuro, amahame y'imikorere, ikoreshwa, inyungu n'uburyo bwo kubungabunga ibikoresho byabumbwe mu buryo bwemewe kugira ngo bigaragaze iki gikoresho cy'ingenzi cy'amashanyarazi.

MCCB, izwi kandi nka molded case circuit breaker, ni igikoresho cy'amashanyarazi gifite imikorere myinshi gikoreshwa mu kurinda sisitemu z'amashanyarazi kurenza urugero, amashanyarazi magufi n'ibindi bibazo by'amashanyarazi. Bitandukanye na miniature circuit breaker zikoreshwa mu ngo,MCCBifite ubushobozi bwo gukoresha ingufu z'amashanyarazi mu rwego rwo hejuru, bityo ikaba ikwiriye gukoreshwa mu nganda no mu bucuruzi. Izi mashini zigabanya ingufu z'amashanyarazi zifite uburyo bugezweho bwo kugenzura amazi adasanzwe kandi zigahagarika inzira y'amashanyarazi kugira ngo zirinde ibikoresho bihujwe.

MCCBbikora ku ihame ry’imikorere ya thermomagnetic kandi byagenewe guhangana neza n’imimerere y’umuvuduko mwinshi n’imigendekere migufi y’amashanyarazi. Ibintu bishyuha bisubiza inyuma y’umuvuduko ukabije w’amashanyarazi mu gihe gito, mu gihe ibintu bikurura amashanyarazi bisubiza inyuma y’imigendekere migufi y’amashanyarazi mu buryo butunguranye. Ubu buryo bubiri butanga uburinzi bwizewe ku makosa atandukanye y’amashanyarazi, bigatumaMCCBamahitamo yizewe ku bahanga mu by'amashanyarazi bakora mu mishinga itandukanye.

Bitewe n'imiterere yayo ikomeye n'ubushobozi bwayo bwo gukoresha umuriro mwinshi,MCCBzikoreshwa cyane mu nganda zitandukanye. Kuva ku nganda z'amashanyarazi n'ibigo by'amashanyarazi kugeza ku nganda zikora n'ibigo by'ubucuruzi, utumashini dukoresha amashanyarazi dufite uruhare runini mu gutuma amashanyarazi adacika intege. Dushobora gukoresha mu buryo butandukanye bw'amashanyarazi, harimo amatara, kugenzura moteri, kurinda transformer, switchboards, nibindi, kugira ngo turinde neza ibikoresho n'abakozi ingaruka z'amashanyarazi.

Imwe mu nyungu z'ingenzi zaMCCBni ubushobozi bwabo bwo guhangana n'imizigo myinshi y'amashanyarazi.MCCBUbusanzwe bipimwa kuva kuri ampeta 10 kugeza kuri ampeta ibihumbi, bityo bikabasha gucunga neza imitwaro iremereye y'amashanyarazi ikunze kuboneka mu nganda. Byongeye kandi, izi circuit breakers zitanga imiterere y'urugendo ishobora guhindurwa, bigatuma abahanga mu by'ikoranabuhanga bahindura urwego rw'uburinzi hakurikijwe ibisabwa byihariye by'ikoranabuhanga ry'amashanyarazi. Ubu buryo bworoshye butuma imikorere myiza kandi bukongera umutekano w'ibikoresho bihujwe.

Kugira ngo hamenyekane ko ibikoresho bigabanya amashanyarazi byakozwe mu buryo busanzwe bihamye kandi birambye, ni ngombwa kubibungabunga buri gihe. Ni ngombwa kugenzura no gupima buri gihe kugira ngo hamenyekane ibimenyetso byo kwangirika, guhuza ibintu bidafite aho bihuriye cyangwa kwangirika kw'ibice byabyo. Byongeye kandi, gukurikiza amabwiriza akwiye yo gushyiraho ni ngombwa kugira ngo hirindwe ingaruka mbi ku mikorere y'ibikoresho bigabanya amashanyarazi. Ni ngombwa kandi kubungabunga ahantu hakikije hasukuye kandi hatarimo ivumbi n'imyanda bishobora kugira ingaruka ku mikorere yabyo. Gukurikiza ubu buryo bwo kubungabunga bizamura igihe cyo kubaho kwabyo.MCCBno kugabanya ibyago byo gucika kw'amashanyarazi.

Muri make,imashini igabanya urujya n'uruza rw'amasasu (MCCB)ni igikoresho cy'amashanyarazi cy'ingenzi kugira ngo sisitemu zitandukanye z'amashanyarazi zikore neza mu mutekano. MCCB zikoreshwa cyane mu nganda no mu bucuruzi kubera ubushobozi bwazo bwo kurinda umuvuduko mwinshi w'amashanyarazi, imiyoboro migufi, n'ibindi bibazo by'amashanyarazi. Ifite amanota menshi y'amashanyarazi, imiterere y'urugendo ihinduka, kandi yizewe bituma iba nziza ku bahanga bashaka uburinzi bw'amashanyarazi bwiza kandi butekanye. Binyuze mu gukurikiza amabwiriza yo kubungabunga, ubuzima bw'amashanyaraziMCCBbishobora kongerwamo imbaraga, ibyo bikaba bigira uruhare mu mutekano rusange no mu kwizerwa kw'uburyo bw'amashanyarazi.
