KunzwisisaMCCBuyeMCBZvikamu Zvikuru zveMasisitimu Emagetsi
Munyaya dzemagetsi nemagetsi, tinowanzo sangana nemashoko ekuti “molded case circuit breaker (MCCB)” uye “miniature circuit breaker (MCB)”. Midziyo yese miviri inoita basa rakakosha mukudzivirira macircuit kubva pakuwanda kwemagetsi uye mashort circuit, asi mashandisirwo awo nemagadzirirwo awo anosiyana. Chinyorwa chino chichaongorora zvakadzama maficha, mabasa, uye mashandisirwo emamolded case circuit breakers (MCCB) nemaminiature circuit breakers (MCB), uye chicharatidza kukosha kwawo mukuona kuchengetedzeka uye kushanda zvakanaka kwemagetsi.
Chii chinonzi MCB?
Chinopwanya dunhu diki (MCB) chishandiso chakagadzirwa kuchengetedza macircuit emagetsi kubva pakuwanda kwemagetsi uye ma short circuit. Ma MCB anowanzo shandiswa pamabasa ekugara uye ekutengeserana ane current ratings yakaderera, inowanzo bva pa 0.5A kusvika 125A. Kana paine chikanganiso, anobvisa dunhu otomatiki, nokudaro achidzivirira kukuvara kwemidziyo uye achideredza njodzi yekubvira kwemoto.
MaMinitary circuit breakers (MCBs) anoshanda pasi pemitemo yekupisa uye yemagnetic tripping. Iyo thermal tripping mechanism inoshandiswa kupindura mamiriro ekuwedzera, nepo magnetic tripping mechanism inoshandiswa kupindura mamiriro eshort circuit. Iyi mashandiro maviri inoita kuti maminiary circuit breakers akwanise kupa dziviriro yakavimbika kune akasiyana masisitimu emagetsi. Pamusoro pezvo, maminiary circuit breakers ari nyore kudzoreredza mushure mekudonha, izvo zviri nyore kushandisa uye zvinobvumira kushanda zvakanaka mukushandiswa kwezuva nezuva.
Chii chinonzi MCCB?
Molded Case Circuit Breakers (MCCBs) zvishandiso zvakasimba zvinowanzo shandiswa pa100A kusvika 2500A. MCCBs dzinowanzo shandiswa munzvimbo dzemaindasitiri nedzemabhizinesi uko mitoro yemagetsi yakakura. Kufanana neMCBs, MCCBs dzinodzivirira kubva pakuwanda kwemagetsi uye mashort circuits, asi dzine zvinhu zvepamusoro-soro, zvinosanganisira magadzirirwo ekufamba anogadziriswa uye kugona kubata ma fault currents akakwira.
Mamolded case circuit breakers (MCCBs) ane chimiro chemolded case chinochengetedza zvikamu zvemukati, zvichipa kugara kwenguva refu uye dziviriro kubva kuzvinhu zvakatipoteredza. Anowanzo sanganisira zvimwe zvinhu zvakaita sekudzivirira zvikanganiso zvepasi uye kugona kutaurirana, zvichivabvumira kubatanidzwa mumasisitimu emagetsi akaomarara. Izvi zvinoita kuti maMCCB akwanise kushandiswa mumafekitori ekugadzira, nzvimbo dzedata, uye zvivakwa zvikuru zvemabhizinesi.
Misiyano mikuru pakati peMCB neMCCB
1. Rated current: Musiyano mukuru pakati peMinitary Circuit Breaker (MCB) neMolded Case Circuit Breaker (MCCB) i rated current yavo. MCB dzakakodzera kushandiswa kwe low current (kusvika ku 125A), nepo MCCB dzakakodzera kushandiswa kwe high current (100A kusvika 2500A).
2. Mashandisirwo: MaMCB anonyanya kushandiswa mumabasa ekugara uye ekutengeserana akareruka, nepo maMCCB akagadzirirwa kushandiswa mumaindasitiri uye mumabhizinesi makuru.
3. Nzira Yekugumburisa: MaMCB anowanzova nemagadzirirwo akagadzika ekugumburisa, nepo maMCCB anowanzova nemagadzirirwo anogadzirisika ekugumburisa, zvichibvumira kugadziriswa zvichienderana nezvinodiwa zvemutoro.
4. Saizi uye Dhizaini: MaMinitary circuit breakers (MCBs) madiki uye madiki, zvichiita kuti akwanise kushandiswa munzvimbo dzine nzvimbo shoma. Kusiyana neizvi, maMolded Case Circuit Breakers (MCCBs) akakura, akaomarara, uye akagadzirwa kuti akwanise kutakura zvinhu zvakawanda zvemagetsi.
5. Mutengo: Kazhinji, maMCB anodhura zvishoma kana akashandisa simba shoma, nepo maMCCB achidhura zvakanyanya nekuda kwehunhu hwawo hwepamusoro uye mareti akakwira.
Mukupedzisa
Muchidimbu, maMCCB nemaMCB zvese zvikamu zvakakosha mumasisitimu emagetsi, uye chimwe nechimwe chine mabasa akasiyana zvichienderana nezvinodiwa pakushandisa. Kunzwisisa musiyano uripo pakati pezvishandiso zviviri izvi kwakakosha pakusarudza mhinduro yakakodzera yekudzivirira dunhu. Ingave yekushandisa mudzimba kana mumaindasitiri, kuve nechokwadi chekushandiswa kwakakodzera kweMCCB nemaMCB kwakakosha pakuchengetedza kuchengetedzeka kwemagetsi, kushanda zvakanaka, uye kuvimbika. Sezvo tekinoroji ichiramba ichichinja, basa remacircuit breaker aya richaramba riri chikamu chakakosha chekushanda kwakachengeteka kwemasisitimu emagetsi pasi rese.
