KunzwisisaMaputsi edunhu: Zvishandiso Zvakakosha Zvekuchengetedza MuMasisitimu Emagetsi
Munyika yeinjiniya yemagetsi uye kuchengetedzeka kwemba, izwi rekuti "circuit breaker" rinonyanya kutaurwa. Circuit breaker chishandiso chakakosha chakagadzirirwa kuchengetedza macircuit emagetsi kubva pakuzara uye ma short circuit, zvichiita kuti masisitimu emagetsi nevaya vanoashandisa vachengetedzeke. Chinyorwa chino chinoongorora zvakadzama mashandiro, mhando, uye kukosha kwema circuit breaker mumasisitimu emagetsi emazuva ano.
Chii chinonzi circuit breaker?
Circuit breaker iswitch inodzima magetsi mucircuit kana yaona 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 iyo inopisa uye inokotama kana magetsi akakwira zvakanyanya. Kana bimetallic strip ikakotama kusvika pamwero wakati, inoita kuti circuit breaker ivhurike, zvichikanganisa circuit.
2. Maitiro emagnetic: Maitiro aya anoenderana nesimba re electromagnetic. Kana circuit pfupi ikaitika, kuputika kwemagetsi kamwe kamwe kunoita kuti simba remagnetic rive rakasimba zvakakwana kuti rikweve lever, nokudaro richityora circuit.
Mamwe macircuit breaker emazuva ano anobatanidza nzira dzese dziri mbiri dzekudzivirira kwakasimba uye anozivikanwa se "dual function" circuit breakers.
Mhando dzemacircuit breakers
Kune mhando dzakasiyana dzemacircuit breaker, imwe neimwe iine chinangwa chayo:
1. MaStandard Circuit Breakers: Aya ndiwo macircuit breakers anowanikwa zvakanyanya muzvivakwa zvekugara uye zvemabhizinesi. Anodzivirira kubva pakuzara kwemagetsi uye mashort circuit.
2. Ground Fault Circuit Interrupter (GFCI): Macircuit breaker aya akagadzirirwa kudzivirira zvikanganiso zvepasi, zvinoitika kana magetsi achibuda kubva mucircuit yaanoda. MaGFCI anowanzo shandiswa munzvimbo dzine mvura dzakadai sedzimba dzekugezera nemakicheni.
3. Arc Fault Circuit Interrupter (AFCI): AFCI dzakagadzirirwa kuona zvikanganiso zve arc zvinogona kukonzera moto wemagetsi. Dzinonyanya kubatsira mumakamuri ekutandarira nemakamuri ekurara.
4. MaMinitary Circuit Breakers (MCBs): Macircuit breakers aya anoshandiswa mukushandiswa kwevoltage yakaderera uye akagadzirwa kuti agumbuke pamagetsi chaiwo.
5. Mudziyo weMagetsi Akasara (RCD): Kufanana neGFCI, RCD inodzivirira kuvhunduka kwemagetsi nekuona kusarongeka kwemagetsi.
Kukosha kweVapambi veDunhu
Kukosha kwemacircuit breaker hakufanirwe kutaurwa zvakanyanya. Ndiwo mutsetse wekutanga wekudzivirira njodzi dzemagetsi. Nekudzima magetsi otomatiki panguva dzenjodzi, macircuit breaker anobatsira kudzivirira moto wemagetsi, kukuvara kwemidziyo, uye kukuvara kwevanhu.
Pamusoro pezvo, macircuit breaker anobatsira kuvandudza kushanda zvakanaka kwemasystem emagetsi. Anotarisira mutoro wemagetsi zvakachengeteka, zvichiita kuti macircuit ashande mukati mesimba rawo rakagadzirwa. Izvi hazvingogumiri pakuwedzera hupenyu hwemidziyo, asi zvinoderedzawo kushandiswa kwesimba.
ZVINOKOSHA
Mukupedzisa, macircuit breaker chikamu chakakosha chemagetsi emazuva ano. Akakosha pakuchengetedzeka kwedzimba nemabhizinesi nekuti anodzivirira kuwandisa kwemagetsi, mashort circuit, uye mamwe matambudziko emagetsi. Kunzwisisa mhando dzakasiyana dzemacircuit breaker uye mashandiro awo kunogona kubatsira vanhu kuita sarudzo dzine ruzivo nezvemagetsi avo, zvichizovandudza kuchengetedzeka uye kushanda zvakanaka. Sezvo tekinoroji ichiramba ichichinja, macircuit breaker pasina mubvunzo achaita basa guru mune ramangwana rekuchengetedza magetsi.
