Igisobanuro cy'ibipimo bitandukanye mu gikoresho cyo gukata uruziga rw'imashini (MCCB)

Utwuma dukoresha imashini zicana imigozi (MCCB) ni ingenzi mu miyoboro y'amashanyarazi, bitanga uburinzi ku miyoboro migufi n'ibintu byinshi biremereye. Gusobanukirwa ibipimo bitandukanye biri mu gice cya MCCB ni ingenzi kugira ngo sisitemu y'amashanyarazi ikore neza kandi igire umutekano.

Voltage Ue ifite ingano ni voltage ya sisitemu, iri hejuru ya 5% kurusha voltage nominel ku mutwaro w'amashanyarazi. Imashini igabanya urujya n'uruza rw'amashanyarazi ya pulasitiki yagenewe gukora ifite voltage ihangana na impulse Uimp=12KV hamwe na voltage ifata Ui 400V ifite ingano. Tugomba kumenya ko voltage y'urusobe rw'amashanyarazi itagomba kurenza voltage ifata Ui kugira ngo hirindwe ibyago bishobora kubaho.

Igipimo cy’ubu cya 125 Amp kigaragaza ubushobozi ntarengwa bwo gutwara umuriro bwa MCCB. Byongeye kandi, igipimo cy’ubushyuhe bw’akazi II cy’irekurwa rya rukuruzi ni 10In, aho In ikubye inshuro 10 ubushyuhe bw’amashanyarazi (1250A), bigatuma habaho gukora vuba kandi neza mu gihe cy’igihe gito.

Ku ruhande rw'iburyo rw'agasanduku k'urukiramende gakozwe mu buryo bwa "module case breaker", "limit limit limit short-circuit segmenting capacity" Icu=35KA hamwe n'ubushobozi bwo gukoresha short-circuit case breaker "Ics=22KA" bigaragaza ubushobozi bw'agasanduku k'urukiramende gakozwe mu buryo bwa "module case breaker" bwo guhangana n'ibibazo by'urukiramende rugufi rudahungabanyije umutekano. MCCB yagenewe kugira ubushyuhe buri hagati ya -5°C na 40°C n'umuvuduko wa 50/60 Hz, bigatuma ikwirakwira mu bihe bitandukanye by'ibidukikije.

Byongeye kandi, MCCB yubahiriza amabwiriza agenga imikorere ya IEC/EN60947-2, igenzura ko amabwiriza agenga ubuziranenge n'umutekano yubahirizwa. Iri tegeko rishimangira ubwizerwe n'imikorere ya MCCB, riha abakoresha amahoro yo mu mutima ku bijyanye n'imikorere yayo myiza no kuramba kwayo igihe kirekire.

Muri make, gusobanukirwa ibipimo biri mu gipangu cya MCCB ni ingenzi cyane mu guhitamo igikoresho gikwiye cyo kurinda urujya n'uruza rw'amashanyarazi. Kubera imiterere yacyo ikomeye no kubahiriza amabwiriza agenga umusaruro, MCCB ikora neza kandi yizewe mu buryo bwizewe mu bikorwa bitandukanye.
