Basa reMCB

Muchina wedunhu mudiki (MCB) dzinoita basa rakakosha pakuona kuti midziyo yemumba nemidziyo yemagetsi yakachengeteka uye yakachengeteka. Maminiature circuit breakers anoshandiswa zvakanyanya kudzivirira kuwandisa, mashort circuit uye kubuda kwemvura, nokudaro achidzivirira michina kubva mukukuvadzwa uye kuderedza kushandiswa kwesimba. Kukura kwayo kudiki, nyore kuisa, kuvimbika kwakanyanya uye kushanda zvakanaka kwemari zvinoita kuti ive chinhu chakakosha mumasisitimu emagetsi.

Rimwe remabasa makuru eMCBs nderekudzivirira mafambiro emagetsi mapfupi. Kana paine zvikanganiso zvemagetsi mapfupi uye magetsi ari mumutsara akakura zvakanyanya, miniature circuit breaker inoshandisa simba remagetsi rinogadzirwa ne electromagnetic coil kufambisa simbi, kusunda push rod kuti ivhurike, uye kubvisa dunhu munguva pfupi. Isingasviki masekondi 0.1. Kupindura uku nekukurumidza kune zvikanganiso zvemagetsi mapfupi kunobatsira kudzivirira kukuvara kunogona kuitika kumidziyo uye kunovimbisa kuchengetedzeka kwemasisitimu emagetsi.

Pamusoro pekudzivirira ma "short circuit", ma "MCB" akagadzirwawo kuti ape dziviriro ye "overload". Kana "current" iri mumutsara ikapfuura "rated current" yakarongwa asi ichiri pasi pe "set short-circuit current value", zvichikonzera "overload fault", chinhu che "thermal bimetallic" chiri mu "miniature circuit breaker" chinokotama uye chinodzivisa "lock", nokudaro chichityora "circuit". Nguva yekutyoka inoshanduka zvichienderana nehukuru hwe "overload current", uye saizi dzakasiyana dze "current" dzinoenderana nemazinga akasiyana ekunonoka. Iyi nzira inobatsira kudzivirira michina kubva pakupisa zvakanyanya uye kukuvara kunogona kukonzerwa nekudzoreredza kwenguva yakareba.

Pakufunga nezvekugona kuputsa maMCB, zvakakosha kuziva kuti akagadzirwa kuti akwanise kupatsanura macircuit breaker akasiyana-siyana. Kugona kuputsa macircuit breaker (Icn) kwema general small circuit breaker anowanzova 6A kusvika 63A, ayo kugona kuputsa macircuit breaker e6A kusvika 40A small circuit breaker ari 6KA, uye kugona kuputsa macircuit breaker e50A kusvika 63A small circuit breaker ari 4.5KA. Pamusoro pezvo, kugona kuputsa macircuit breaker (Ics) kunotsanangurwawo kuti 6KA yema circuit breaker e6A kusvika 40A miniature breaker uye 4.5KA yema circuit breaker e50A kusvika 63A miniature. Kugona uku kunokanganisa kunoita kuti ma miniature circuit breaker agone kukanganisa macircuit pasi pemamiriro akasiyana-siyana e short circuit, zvichiwedzera dziviriro kumasystem emagetsi.

Kushanda nesimba kweMCB kunoita kuti ive chinhu chakakosha pakudzivirira midziyo yemumba nemidziyo yemagetsi. Kukwanisa kudzivirira kuwanda kwemidziyo, mapfupi emagetsi uye kubuda kwemvura hakungodziviriri midziyo chete asiwo kunobatsira kuderedza kushandiswa kwesimba. MCBs diki, dziri nyore kuisa, dzakavimbika zvikuru uye dzinodhura zvishoma, dzichipa mhinduro inodhura yekuona kuchengetedzeka nekuchengetedzwa kwemagetsi. Ingave iri yekushandisa mudzimba, mumabhizinesi kana mumaindasitiri, maminiature circuit breakers akakosha pakuchengetedza kuchengetedzeka kwemidziyo yemagetsi.

Mutai Group yawana ruzivo rwemakore anopfuura gumi mukugadzira nekutengesamacircuit breakers, zvinobata, maswichi ekutamisa otomatiki ane simba remagetsi maviri (ATS) nedzimwe nzvimbo dzakabatana. Tinotarisira nemoyo wese mukana wekushanda nemi.
