Chinopwanya dunhu diki (MCB)mudziyo unoshandiswa zvakanyanya mumagetsi kudzivirira macircuit kubva pakuzara kwemagetsi uye ma short circuit. Chinhu chakakosha pakuona kuchengetedzeka kwemagetsi uye kudzivirira kukuvara kwemidziyo, michina uye waya. Muchinyorwa chino, tichaongorora kukosha kwema miniature circuit breakers uye mashandiro awo.
A kadiki kekupwanya dunhuimhando yecircuit breaker yakagadzirirwa kushandiswa kwemagetsi mashoma. Yakabatana muhukuru uye inogona kuiswa zviri nyore pamatanho eDIN akajairwa. Basa guru reMCBndeyekumisa otomatiki kuyerera kwemagetsi mudunhu kana paine kuwandisa kwemagetsi kana kuti kupfupika kwemagetsi.
Chinhu chikuru chakanakiramadiki ecircuit breakerskugona kuona nekukurumidza uye nemazvo uye kupindura kumamiriro emagetsi asina kujairika. Kana magetsi adarika kukosha kwakarongwa, chinhu chinodziya chiri mukadiki kekupwanya dunhuinopisa, zvichiita kuti circuit breaker igumbuke. Saizvozvowo, kana circuit pfupi ikadonha, chinhu chine magineti chinotenderera mukatiMCBInoona mafambiro emagetsi kamwe kamwe uye inogumbura circuit breaker.
Chimwe chezvakanakira zvakakosha zvekushandisakadiki kekupwanya dunhukugona kwayo kugadziriswazve nemaoko mushure merwendo. Kusiyana nedzimwe mhando dzemacircuit breakers, maMCB anogona kugadziriswa zviri nyore nekudzosera switch panzvimbo yeON, zvichidzosera simba kucircuit. Izvi zvinobvisa kudiwa kwekutsiva kana kugadzirisa, zvichiita kuti maMCB ave mhinduro inodhura yekudzivirira masisitimu emagetsi.
Imwe mukana wekushandisa ma "miniature circuit breakers" kugona kwawo kudzivirira ma "circuit" ega ega. Mu "system" yemagetsi yakajairika, ma "circuit" akasiyana anogona kunge aine mazinga akasiyana ezvinodiwa pari zvino. Nekuisa "system" iyi, ma "circuit" akasiyana anogona kunge aine mazinga akasiyana ezvinodiwa pari zvino.MCBspadunhu rega rega, njodzi yekuwanda kwemagetsi kana mapfupi emagetsi anokanganisa sisitimu yese inogona kuderedzwa zvakanyanya. Izvi zvinoita kuti pave nekupatsanurwa kwemafault zviri nani uye zvinovandudza kuvimbika kwese kwekuisa magetsi.
Pamusoro pezvo, ma "miniature circuit breakers" anopa kurongeka kwakasarudzwa. Izvi zvinoreva kuti kana paine dambudziko rakadai sekuwanda kwemagetsi kana kuti short circuit, miniature circuit breaker chete ndiyo inokanganiswa nedambudziko racho, zvichisiya mamwe ese asina dambudziko. Izvi zvinobatsira kuona nekugadzirisa zviri nyore ma "circuit disadvantages", zvichichengetedza nguva nesimba pakutsvaga matambudziko.
Kuwedzera pamabasa ekudzivirira, ma "miniature circuit breakers" anowanzova nemabasa akavakirwa mukati, akadai se "indicator lights" kana "trip indicators". Aya ma "indicators" anopa chiratidzo chekuona kana "MCByagumburwa, zvichibatsira mushandisi kukurumidza kuona nekugadzirisa chikonzero chekukundikana kwemagetsi.
Mukupedzisa,madiki ecircuit breakerszvinhu zvakakosha mumasisitimu emagetsi, zvichivimbisa kuchengetedzeka uye kuvimbika kwekuisa kwese. Kugona kwavo kuona mamiriro emagetsi asina kujairika uye kukanganisa kufamba kwemagetsi nekukurumidza kunobatsira kudzivirira kukuvara kwemidziyo netambo, uye kunodzivirira kubva kunjodzi dzemagetsi dzakadai semoto uye kuvhunduka kwemagetsi. Nehukuru hwavo hudiki, kuiswa kuri nyore uye zvinhu zvinogona kugadziriswazve,MCBsinopa mhinduro isingadhuri yekudzivirira macircuit. Ingava mudzimba, mumabhizinesi kana mumaindasitiri, maminiature circuit breakers anoita basa rakakosha mukuchengetedza kuchengetedzeka kwemagetsi.
