Kunzwisisa Ma Circuit Breakers: Zvishandiso Zvakakosha Zvekuchengetedza MuMasisitimu Emagetsi**
Izwi rekuti "circuit breaker" rakajairika munyika yeinjiniya yemagetsi uye kuchengetedzeka kwemba. Macircuit breaker zvishandiso zvakakosha zvinodzivirira macircuit emagetsi kubva pakuzara uye mashort circuit, zvichivimbisa kuchengetedzeka kwemasystem emagetsi nevaya vanoashandisa. Chinyorwa chino chichanyatsoongorora mashandiro, mhando, uye kukosha kwemacircuit breaker mumasystem emagetsi emazuva ano.
Chii chinonzimuputsi wedunhu?
Circuit breaker iswitch inodzima kufamba kwemagetsi mucircuit kana ikaona chimwe chinhu chisina kujairika, senge overload kana short circuit. Kusiyana nemafuse, ayo anofanira kutsiviwa mushure mekunge aputika, macircuit breaker anogona kudzoserwa patsva mushure mekunge adonha, zvichiita kuti ave sarudzo iri nyore uye inoshanda yekuchengetedza magetsi. Anowanzoiswa mumapaneru emagetsi uye akakosha kudzivirira moto wemagetsi nekukuvara kwemidziyo.
Macircuit breaker anoshanda sei?
Macircuit breaker anoshanda zvichibva pamatanho maviri makuru: thermal uye magnetic.
1. Kushandiswa kwekupisa: Iyi nzira inoshandisa bimetallic strip. Kana magetsi akawandisa, bimetallic strip inodziya uye inokotama. Kana ikakotama kusvika pamwero wakati, ichaita kuti circuit breaker ivhurike, nokudaro ichibvisa circuit.
2. Maitiro emagnetic: Maitiro aya anoenderana nesimba re electromagnetic. Kana circuit pfupi ikaitika, kupinda kwemagetsi kamwe kamwe kunoita kuti simba remagnetic rive rakasimba zvakakwana kuti rikwevere lever uye riparadze circuit.
Mamwe macircuit breaker emazuva ano anobatanidza nzira dzese dziri mbiri dzekudzivirira zvakanyanya, zvichipa mhinduro yakavimbika kune dzakasiyana-siyana dzemagetsi.
Mhando dzemacircuit breakers
Kune mhando dzakasiyana dzemacircuit breaker, imwe neimwe iine chinangwa chayo:
1. Standard Circuit Breaker: Iyi ndiyo mhando yecircuit breaker inowanikwa zvakanyanya muzvivakwa zvekugara uye zvemabhizinesi. Inoshandiswa kudzivirira kubva pakuzara kwemagetsi uye mashort circuit.
2. Ground Fault Circuit Interrupter (GFCI): Iyi circuit breaker inoshandiswa kudzivirira zvikanganiso zvepasi. Ground fault idambudziko rinoitika kana magetsi achibuda kubva mudunhu rakatarwa. GFCI dzinowanzo shandiswa munzvimbo dzine mvura dzakadai sedzimba dzekugezera nemakicheni kudzivirira kurohwa nemagetsi.
3. Arc Fault Circuit Interrupter (AFCI): MaAFCI anoshandiswa kuona zvikanganiso zvearc zvinogona kukonzera moto wemagetsi. Anonyanya kubatsira munzvimbo dzekugara uko njodzi yemoto wemagetsi yakanyanya.
4. **Miniature Circuit Breaker (MCB)**: Inoshandiswa mukushandiswa kwemagetsi mashoma, yakagadzirirwa kudzivirira kuwandisa kwemagetsi uye mapfupi mumatunhu madiki.
5. MaResidual Current Circuit Breakers (RCCB): Macircuit breakers aya anoona kusawirirana kwemagetsi uye anonyanya kushandiswa kudzivirira kuvhunduka kwemagetsi.
Kukosha kweVapambi veDunhu
Kukosha kwema "circuit breakers" hakufanirwe kutaurwa zvakanyanya. Ndiwo mutsetse wekutanga wekudzivirira njodzi dzemagetsi, achidzivirira hupenyu nepfuma. Ma "circuit breakers" anodzima magetsi otomatiki mumamiriro ezvinhu ane njodzi, zvichibatsira kudzivirira moto wemagetsi, kukuvara kwemidziyo, uye kukuvara kwevanhu.
Pamusoro pezvo, macircuit breaker anobatsira kuvandudza kushanda zvakanaka kwemasystem emagetsi. Nekudzivirira kuwandisa kwemagetsi, macircuit breaker anobatsira kuchengetedza kushanda zvakanaka kwemidziyo nemidziyo, zvichiwedzera hupenyu hwayo uye zvichideredza mari yekugadzirisa.
Mutsetse Wekupedzisira
Zvose zviri zviviri, macircuit breaker chikamu chakakosha chemagetsi emazuva ano. Kugona kwawo kuona nekugadzirisa zvikanganiso zvemagetsi hakungobatsiri chete kuchengetedzeka, asiwo kunoita kuti michina yemagetsi ishande zvakanaka. Sezvo tekinoroji ichienderera mberi, macircuit breaker anotarisirwawo kushanduka, achisanganisira zvinhu zvakangwara kuti awedzere kuvandudza kuchengetedzeka nekuvimbika. Kunzwisisa basa remacircuit breaker kwakakosha kune chero munhu anoshanda nemidziyo yemagetsi, pamwe nevaridzi vedzimba vanoda kuona kuchengetedzeka kwemagetsi avo.
