KunzwisisaMCCBuyeMCB: Misiyano Mikuru uye Mashandisirwo
Muminda yeinjiniya yemagetsi nekudzivirira macircuit, mazwi maviri anowanzo shandiswa: MCB (miniature circuit breaker) uye MCCB (molded case circuit breaker). Midziyo yese miviri inoita basa rakakosha rekudzivirira macircuit kubva pakuwanda kwemagetsi uye mashort circuit, asi akasiyana zvakanyanya mukugadzirwa kwawo, mashandisirwo awo, uye kugona kwawo kushanda. Chinyorwa chino chinangwa ndechekujekesa mutsauko uripo pakati peMCBs neMCCBs, zvichikubatsira kunzwisisa kuti ndeapi uye nei uchifanira kushandisa imwe neimwe.
Chii chinonzi MCB?
Chinopwanya dunhu diki (MCB) chishandiso chidiki chinoshandiswa kudzivirira macircuit emagetsi kubva pakuwanda kwemagetsi uye ma short circuit. Ma MCB anowanzo shandiswa muzvivakwa zvekugara uye zvemabhizinesi zvine current ratings yakaderera, inowanzo tangira pa 0.5A kusvika 125A. Kana current ikadarika mwero wakatarwa, MCB inongoerekana yadonha, ichidzivirira kukuvara kunogona kuitika kucircuit nemidziyo yakabatana.
MaMinitary circuit breakers (MCBs) anopa nguva yekupindura nekukurumidza, izvo zvakakosha pakuderedza kukuvara kunokonzerwa nezvikanganiso. Anogona zvakare kugadziriswa, zvichireva kuti kana dambudziko rapera, MCB inogona kugadziriswa zviri nyore pasina kutsiva. Ichi chinhu chinoita kuti MCBs ive sarudzo inozivikanwa yekudzivirira macircuit emwenje, ma socket emagetsi, uye midziyo midiki.
Chii chinonzi MCCB?
Ma "molded case circuit breakers" (MCCBs), kune rumwe rutivi, akasimba uye akagadzirirwa kushandiswa kwemagetsi epamusoro, anowanzo tangira pa100A kusvika pa2500A. Ma "MCCBs" anowanzo shandiswa munzvimbo dzemaindasitiri nedzemabhizinesi dzine magetsi akawanda. Anopa dziviriro yekudzivirira kukanganiswa kwemagetsi, kupfupika kwemagetsi, uye kutadza kushanda kwepasi, zvichiita kuti akwanise kushandiswa zvakasiyana-siyana.
MaMolded case circuit breakers (MCCBs) ane magadzirirwo erwendo anogadziriswa, zvichibvumira vashandisi kugadzirisa mwero wekudzivirira zvinoenderana nezvinodiwa zvesystem yemagetsi. Chinhu ichi chinobatsira zvikuru munzvimbo dzemaindasitiri uko zvinodiwa zvemidziyo zvinogona kusiyana. MaMCCB anowanzo sanganisirawo maficha epamusoro akadai sekutarisa kure uye kutaurirana, zvichivandudza mashandiro awo musystem dzemagetsi dzakaoma.
Misiyano mikuru pakati peMCB neMCCB
1. Kuyera Kwazvino**: Musiyano mukuru pakati peMCB neMCCB ndewekuyera kwavo kwazvino. MCB yakakodzera kushandiswa kwemagetsi mashoma (kusvika ku125A), nepo MCCB yakakodzera kushandiswa kwemagetsi akawanda (100A kusvika 2500A).
2. Kugadziriswa: MaMCB ane marongero erwendo akagadzika, nepo maMCCB achipa marongero erwendo anogadzika, zvichibvumira kushanduka kukuru mukudzivirira dunhu.
3. Mashandisirwo: MaMCB anonyanya kushandiswa mumabasa ekugara uye ekutengeserana akareruka, nepo maMCCB akagadzirirwa kushandiswa mumaindasitiri uye mumabhizinesi makuru, ayo anosanganisira mitoro yakakura uye masisitimu akaomarara.
4. Saizi uye Dhizaini: MaMinitary circuit breakers (MCBs) anowanzova madiki uye madiki pane mamolded case circuit breakers (MCCBs), zvichiita kuti zvive nyore kuisa munzvimbo diki. MaMolded case circuit breakers (MCCBs) akakura, anoda nzvimbo yakawanda, uye anowanzoiswa muma switchgear assemblies.
5. Mutengo: MaMinitary circuit breakers (MCBs) anowanzo kudhura zvishoma pane ma molded case circuit breakers (MCCBs), zvichiita kuti ave mhinduro inoshanda pakushandisa madiki. Zvisinei, kuwedzera kwekushanda kwawo uye mashandiro awo kunoita kuti ave mari inobatsira munzvimbo dzakakura uye dzinoda kushanda zvakanyanya.
Muchidimbu
Muchidimbu, ma "miniature circuit breakers" (MCBs) nema "molded case circuit breakers" (MCCBs) ese ari maviri ane basa rakakosha mukudzivirira ma "circuit", asi mashandisirwo awo uye kugona kwawo zvinosiyana zvakanyanya. Kunzwisisa misiyano iyi kwakakosha pakusarudza mudziyo wakakodzera zvaunoda. Kunyangwe uri kuchengetedza dunhu diki rekugara kana sisitimu hombe yeindasitiri, kusarudza "circuit breaker" kwakakodzera kunovimbisa kuchengetedzeka, kuvimbika, uye kushanda zvakanaka kwemidziyo yako yemagetsi. Gara uchibvunza nyanzvi yemagetsi kana mainjiniya wemagetsi kuti aone mhinduro yakanakisa yemamiriro ako chaiwo.
