Ndeupi musiyano uripo pakati peiyo miniature yedunhu breaker uye molded kesi circuit breaker

Basa rekutanga reiyo miniature circuit breaker (MCB) yedunhu rebreaker enclosures uye yakafararira yedunhu rebreaker zvigadzirwa ndeyekupa gadziriso yekuvaka yemagetsi terminal yekuparadzira michina.Sezvo ese ari maviri ari edunhu mabreaker uye epurasitiki kesi circuit breakers anonyanya kushandiswa kuchengetedza mutsauko pakati pezviviri, kusarudza chinhu chakakodzera chinhu chaicho uye chakakosha.Basa guru reMolded Case Circuit Breaker (MCCB kwenguva pfupi) nderekupa dziviriro yekuremerwa uye kupfupika kwedunhu mune yakaderera-voltage magetsi ekugovera masisitimu uye maseketi ekudzivirira mota.Nekuda kwekuvimbika kwayo uye kugadzikana, chave chinhu chinoshandiswa zvakanyanya muindasitiri.Pazasi pane tsananguro pfupi.Kutanga, ngatitaurei pamusoro pezvakanyanya kufanana.Sezvo vari vaviricircuit breakers, kune zvimwe zvakakosha zvigadzirwa zviyero zvinofanirwa kutevedzera uye kushanda nenzira imwechete.Zvadaro taura nezvekusiyana kwezviviri.Muzhinji, pane zvinotevera zvinotevera: 1. Kusiyana kwemagetsi emagetsi 2. Kusiyana kwemaitiro emagetsi 3. Nzvimbo dzakasiyana dzekushanda dzemapurogiramu Uyezve, kubva pane imwe nzvimbo yekutenga, pane chaizvoizvo zvimwe zvakasiyana pakati pezviviri.Chiyero chazvino Chiyero chepamusoro cheiyo molded case circuit breaker ndeye 2000A.Iyo yepamusoro ikozvino nhanho yediki miniature yedunhu breaker ndeye 125A.Nekuda kwekusiyana kwevhoriyamu, mubasa chairo, nzvimbo inoshanda yepurasitiki kesi circuit breaker inodarikawo iyo miniature circuit breaker, uye waya dzakabatanidzwa dzakakora, dzinogona kusvika kupfuura 35 square metres, nepo miniature circuit breaker inokodzera chete kubatanidza isingasviki 10 square metres..Meter.Mutsara wechiridzwa.Nokudaro, kazhinji, makamuri makuru anonyanya kukodzera pakusarudza plastiki kesicircuit breakerszvichienderana nemamiriro emukati.Kuisa nzira Plastic kesi circuit breakers inonyanya kuisirwa pane screws, zviri nyore kusungirira, kuva nekubatana kwakanaka uye kumhanya zvakanaka.Maminiature edunhu mabreak anonyanya kuiswa panjanji, dzimwe nguva zvichikonzera kusabatana kwakashata nekuda kwekusakwana torque.Nekuda kwenzira dzakasiyana dzekuisa dzevaviri, kuisirwa kwepurasitiki kesi circuit breakers kwakasimba uye kwakaoma kupfuura miniature circuit breakers.kushanda uye kushanda kwenguva refu.Iyo yakaumbwa kesi yedunhu breaker inotora maviri seti yeanopfuura ipfupi-yedunhu midziyo yekugadzirisa, uye iyo overcurrent yekugadzirisa chiitiko kukosha inogona kugadziridzwa nemaoko, zviri nyore uye nekukurumidza.Miniature circuit breakers vanoshandisa imwechete seti ye overcurrent uye mapfupi emagetsi emagetsi, ikozvino haigone kugadziriswa, uye dzimwe nguva dambudziko harigone kugadziriswa.Molded case circuit breaker dzine nzvimbo yakakura, chivharo chekudzimisa arc, simba rekudzima arc yakasimba, inokwanisa kumirisana nehombe yedunhu diki, haisi nyore kukonzeresa kupfupika, uye kuve nehupenyu hwesevhisi hurefu kupfuura madiki madiki edunhu.Application Flexibility Panyaya iyi, maplastic case circuit breakers anonyanya kuoneka, uye kuseta kwawo kuchinjika kwakakwirira pane kuya kwemadiki madiki edunhu.Zvishandiso zvekudzivirira zveanopfuura uye overcurrent epurasitiki kesi circuit breakers zvakapatsanurwa, uye kukosha kwekuita kwe overcurrent kugadzirisa kunogona zvakare kuchinjika.Iyo overcurrent gadziriso uye overcurrent kuchengetedzwa kwemaminiature edunhu mabreaker akabatana mudziyo, uye pane zvimwe zvinoshomeka mukugadzirisa kuchinjika.Zvichienderana nezviri pamusoro, zvinoita sekunge madiki madiki mabreaker ari panjodzi, asi kutaura zvazviri, mune dzimwe nguva, isu tichiri kusarudza madiki madiki edunhu.Semuenzaniso, kana kuchengetedzwa kwenzira kunofanirwa kuvandudzwa, iyo miniature yedunhu breaker ine yakakwirira chiito senitivity uye nekukurumidza kutyora kukurumidza, izvo zvinonyanya kubatsira kuchengetedza nzira uye midziyo yemagetsi.
