Mabasa uye Mabhenefiti eMinitary Circuit Breakers (MCBs)

Nzwisisa basa reMCBmumagetsi

MaMinitary circuit breakers (MCBs) zvinhu zvakakosha mumagetsi emazuva ano, zvichipa dziviriro yakakosha kubva pakuwanda kwemagetsi uye mashort circuit. Sezvo kuchengetedzeka kwemagetsi kuri kuramba kuchikosha munzvimbo dzekugara nedzekutengeserana, kunzwisisa mashandiro uye mabhenefiti eMCBs kwakakosha kune chero ani zvake ari mukuisa kana kugadzirisa magetsi.

Chii chinonzi MCB?

MCB mudziyo wemagetsi wakagadzirirwa kudzima circuit yega kana paine dambudziko, senge overload kana short circuit. Kusiyana nemafuse echinyakare, ayo anofanira kutsiviwa mushure mekunge aputika, MCB inogona kudzoserwa patsva mushure mekunge yadonha, zvichiita kuti ive sarudzo iri nyore uye inoshanda yekudzivirira circuit.

Mashandiro anoita MCB

Kushanda kweMCB kwakavakirwa pamatanho maviri makuru: kupisa uye magineti. Muchina wekupisa unopindura mumamiriro ekunyanyisa, apo magetsi anodarika kugona kwakayerwa kwedunhu. Mvura yakawandisa inopisa bimetallic strip, zvichiita kuti ikotame uye pakupedzisira igumbuke. Muchina wemagetsi, kune rumwe rutivi, unopindura kumatanho mapfupi, uko kukwira kwemagetsi kunoitika ipapo ipapo uye kwakanyanya kupfuura zvakajairwa. Muchiitiko ichi, coil yemagetsi inogadzira simba remagineti rinogumbura circuit breaker nekukurumidza, zvichidzivirira kukuvara kwesystem yemagetsi.

Mhando dzeMCBs

Kune mhando dzakasiyana dzeMCB, imwe neimwe iine chinangwa chayo. Mhando dzakajairika dzinosanganisira:

1. Rudzi B MCB: Yakakodzera kushandiswa mudzimba uye inogona kubata kuwanda kwemagetsi akawandisa ka3 kusvika ka5 kupfuura simba remagetsi rakatarwa. Dzakanakira macircuit anodzoreredza mutoro akadai semwenje nekupisa.

2. Type C MCB: Macircuit breaker aya akagadzirirwa kushandiswa mumabhizinesi nemaindasitiri uye anokwanisa kubata overloads inodarika 5 kusvika ku10 current rated. Akakodzera macircuit ane inductive loads akadai semota nematransformer.

3. D-Type MCB: Aya macircuit breaker anoshandiswa mumashandisirwo ane ma inrush currents akawanda, akadai sema motors makuru nema transformers, uye anogona kubata overloads inopetwa ka10 kusvika ku20 kupfuura rated current.

Zvakanakira kushandisa MCB

1. Kuchengetedzeka: Kana tichienzanisa nemafuse, maminiature circuit breakers akachengeteka. Anogona kubvisa circuit nekukurumidza kana paine chikanganiso, zvichideredza njodzi yemoto wemagetsi nekukuvara kwemidziyo.

2. Zviri nyore: Kusiyana nemafuyusi anoda kutsiviwa mushure mekukundikana, maMCB anogona kudzoserwa patsva neswitch iri nyore, zvichideredza nguva yekushanda uye basa rekugadzirisa.

3. Kunyatsoshanda: MaMCB anopa magadzirirwo ekudzivirira akanyatsojeka, zvichiita kuti pave nekudzora zviri nani masisitimu emagetsi. Kunyatsoshanda uku kunobatsira kudzivirira matambudziko ukuwo kuchichengetedza zvakakwana.

4. Dhizaini Yakabatana: MaMCB anowanzova madiki uye madiki kupfuura mafuse ekare, zvichiita kuti zvive nyore kuisa muma switchboard, zvichichengetedza nzvimbo inokosha.

Kuisa uye Kugadzirisa

Kuiswa kweMCB kunofanirwa kutevedzera mitemo yemagetsi uye zvinodiwa kuti ive nechokwadi chekuti yakachengeteka uye inoshanda. Zvakakosha kusarudza mhando yeMCB yakakodzera uye chiyero chayo zvichienderana nezvinodiwa zvekushandisa uye mutoro. Kuongorora kwekugadzirisa kunofanirwawo kuitwa nguva nenguva kuti ive nechokwadi chekuti MCB iri kushanda nemazvo uye kuona chero matambudziko angangoitika asati awedzera.

Muchidimbu

Muchidimbu, ma miniature circuit breakers (MCBs) anoita basa rakakosha mukudzivirira masisitimu emagetsi kubva pakuwanda kwemagetsi uye ma short circuit. Kugona kwawo kupa dziviriro nekukurumidza uye yakavimbika kunoita kuti ave chinhu chakakosha mukuisa magetsi mudzimba nemabhizimisi. Kunzwisisa mhando dzakasiyana dzeMCBs nemashandisirwo adzo kunogona kubatsira kuona kuti masisitimu emagetsi anoshanda zvakachengeteka uye zvinobudirira, zvichizogadzira nharaunda yakachengeteka kune wese munhu. Sezvo tekinoroji ichiramba ichifambira mberi, kukosha kweMCBs mukuchengetedza magetsi kuchawedzera, saka zvakakosha kuti nyanzvi nevaridzi vedzimba vanzwisise mabhenefiti avo nemashandisirwo azvo.
