Molded case circuit breaker(MCCB) inopa dziviriro yekuremerwa uye pfupi dunhu mune yakaderera voltage magetsi ekugovera sisitimu uye mota yekudzivirira loop.Nekuda kwekuvimbika kwayo uye kugadzikana, yakashandiswa zvakanyanya mumaindasitiri.Miniature circuit breaker(MCB) inoshandiswawo muhupamhi uye nhamba huru yezvigadzirwa zvemagetsi emagetsi, basa guru nderekupa dziviriro yekuvaka magetsi emagetsi ekugadzirisa magetsi.Nekuti ese ari maviri ndeemuparadzi wedunhu, uyeMCCBinonyanya kushandiswa kune diki kugona uye kudzima, saka nzwisisa mutsauko pakati pezviviri, sarudza chakakodzera chigadzirwa chiri chechokwadi uye chakakosha.Heino tsananguro inokurumidza.
Ngatitangei neakakosha kufanana, nekuti ese ari maviri anotyora matunhu, ese ari maviri anofanirwa kutevedzera mamwe ekutanga zvigadzirwa zviyero, uye anoshanda nenzira imwechete.Ngatitaure pamusoro pekusiyana pakati pavo.Kazhinji, pane zvinotevera pfungwa:
- Kusiyana kwemagetsi parameters
- Different mechanical parameters
- Nzvimbo dzekushanda dzakasiyana
Kuwedzera kwakaiswa kubva kuAngle yekusarudza uye tenga, taura mashoma ese mutsauko zvakananga.
Current rating
Molded case circuit breakersvane giredhi razvino kusvika 2000A.Iyo yakanyanya giredhi yazvino yeminiature yedunhu breaker iri mukati me125A.Nekuda kwemukana uripo pakati pezviviri mukugona, mune iro basa chairo, iyo inoshanda nzvimbo yeyakaumbwa kesi circuit breaker yakakura kupfuura iyominiature circuit breaker, uye waya yekuwana yakakora, inogona kusvika kupfuura 35 square metres, uyeminiature circuit breakerinokodzera chete kune inotevera 10 square metres yewaya.Naizvozvo, iyo yakajairika yemukati mamiriro, iyo hombe kamuri inonyanya kukodzera kusarudzwa kweakaumbwa kesi circuit breaker.
Installation
Molded case circuit breakerinonyanya kuiswa screw, iri nyore kudzvanya, yakanaka kuonana, yakagadzikana mashandiro.Uye iyo micro circuit breaker inonyanya kuisirwa kuburikidza negwara renjanji, dzimwe nguva nekuda kwekusakwana torque uye kukonzera kusabatana.Nekuda kwemaitiro avo akasiyana ekuisa, akaumbwa edunhu mabreak akanyanya kugadzikana uye haana kuoma kuisa paneminiature circuit breakers.
Kushanda uye hupenyu
Operationally.Molded case circuit breakerinotora maseti maviri emidziyo kuchengetedza overcurrent uye pfupi dunhu zvichiteerana, uye kukosha kwechiito chekudzivirira kwepamusoro kunogona kugadziridzwa nemaoko, zviri nyore uye nekukurumidza.Miniature circuit breakers vanogovera seti yezvishandiso zve overcurrent uye pfupi dunhu, uye yazvino haigone kugadziridzwa, zvichiita kuti nyaya dzakawanda dzitadze kugadzirisa dambudziko.Plastic kesi circuit breaker phase chinhambwe, uye arc chivharo, arc kudzimisa kugona kwakasimba, inogona kutsungirira yakakura pfupi-yedunhu ikozvino, uye hazvisi nyore kukonzeresa nhanho pfupi, kuitira kuti hupenyu hwesevhisi huwedzere kupfuura iyo miniature yedunhu breaker.
Flexibility yekushandiswa
Panyaya iyi,molded case circuit breakersvane mukurumbira, uye kuchinjika kwavo mukuseta kuri nani pane madiki madiki edunhu.The overcurrent uye pfupi dunhu kudzivirira midziyo yeMCCBdzakazvimiririra, uye kukosha kwechiito chekudzivirira kwepamusoro kunogona kugadziridzwa zviri nyore.Iyo pamusoro pekudzivirira ikozvino uye pfupi dunhu kuchengetedzwa kweiyoMCBmidziyo yakabatana, uye pane zvimwe zvinoshomeka mukushanduka kwemitemo.Maererano nepamusoro pemamiriro ezvinhu anoita seMCB mumhepo, asi chaizvoizvo kwenguva yakati, kana kuti inoda kusarudzaMCB.
Semuenzaniso, kudiwa kwekuvandudza kuchengetedzwa kwemutsara, nokuti MCB chiito sensitiy chakakwirira, kuputsa chiito chinokurumidza, chinowedzera kuchengetedza mutsara nemagetsi emagetsi.Zvinogona kuonekwa kuti zvose zviri zviviri zvine zvazvakanakira uye zvakakodzera kushandiswa, kiyi ndeyokunyatsonzwisisa musiyano uripomolded case circuit breakeruye miniature wedunhu breaker, uye zvinoenderana nezvavo zvavanoda kusarudza.
