KunzwisisaMaputsi edunhu: Zvishandiso Zvakakosha Zvekuchengetedza MuMasisitimu Emagetsi
Izwi rekuti "circuit breaker" rakajairika munyika yeinjiniya yemagetsi uye kuchengetedzeka kwemba. Macircuit breaker zvinhu zvakakosha zvinodzivirira macircuit emagetsi kubva pakuzara uye ma short circuit, zvichivimbisa kuchengetedzeka kwemasystem emagetsi nevaya vanoashandisa. Chinyorwa chino chichanyatsoongorora mashandiro, mhando, uye kukosha kwemacircuit breaker mumasystem emagetsi emazuva ano.
Chii chinonzi circuit breaker?
Circuit breaker iswitch yemagetsi 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 yekudzivirira circuit. Macircuit breaker akakosha pakudzivirira moto wemagetsi, kukuvara kwemidziyo, nedzimwe njodzi dzine chekuita nekutadza kushanda zvakanaka kwemagetsi.
Mashandiro anoita macircuit breakers
Macircuit breaker anoshanda zvichibva pamatanho maviri makuru: thermal uye magnetic.
1. Nzira yekudzivirira kupisa: Iyi nzira inoshandisa bimetallic strip inokotama kana magetsi akakwira zvakanyanya. Kana magetsi adarika kukosha kwakatemwa, simbi inokotama zvakakwana kuti itange circuit breaker, nokudaro ichigura circuit.
2. Magnetic mechanism: Iyi mechanism inoenderana nesimba remagetsi. Kana circuit pfupi ikaitika, kupinda kwemagetsi kamwe kamwe kunoita kuti simba remagetsi rive rakasimba zvekudhonza lever uye kupwanya circuit breaker.
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. MaMinitary Circuit Breakers (MCB): Macircuit breakers aya anowanzo shandiswa muzvivakwa zvekugara uye zvemabhizinesi kudzivirira kuwandisa kwemagetsi uye mashort circuits. Akaoma uye anogona kubata magetsi ari pasi kusvika pakati nepakati.
2. Residual Current Circuit Breaker (RCCB): Midziyo iyi inodzivirira kuvhunduka kwemagetsi nekuona kusawirirana kwemagetsi. Kana paine chikanganiso, RCCB inogumburwa yodzima magetsi.
3. MaResidual Current Circuit Breakers (ELCB): Kufanana nemaResidual Current Circuit Breakers (RCCB), maELCB anodzivirira kubva pakukanganiswa kwevhu. Anonyanya kukosha munzvimbo dzine mvura dzakadai sedzimba dzekugezera nemakicheni.
4. MaAir Circuit Breakers (ACB): MaAir circuit breakers anoshandiswa mumaindasitiri kubata magetsi akawanda uye kudzivirira kubva pakuwanda kwemagetsi, ma short circuit, uye ground fault.
5. MaHydraulic Magnetic Circuit Breakers: Aya anowanzo shandiswa mumagetsi makuru uye anopa mhinduro yakasimba yekudzivirira kubva kumafuru emagetsi ane simba rakawanda.
Kukosha kweVapambi veDunhu
Kukosha kwema "circuit breakers" hakufanirwe kutaurwa zvakanyanya. Ndiwo mutsetse wekutanga wekudzivirira njodzi dzemagetsi, achidzivirira hupenyu nepfuma. Ma "circuit breakers" anodzima otomatiki kufamba kwemagetsi 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 anovimbisa kuti michina yemagetsi inoshanda mukati memiganhu yakachengeteka, nokudaro ichiwedzera hupenyu hwayo hwekushanda uye ichideredza mari yekugadzirisa.
Muchidimbu
Zvose zviri zviviri, macircuit breaker chikamu chakakosha chemagetsi emazuva ano. Kugona kwawo kuona nekugadzirisa zvikanganiso zvemagetsi kwakakosha pakuchengetedza uye kushanda zvakanaka. Kunzwisisa mhando dzakasiyana dzemacircuit breaker uye mashandiro awo kunogona kubatsira varidzi vedzimba nemabhizinesi kuita sarudzo dzakakodzera nezvemagetsi avo. Sezvo tekinoroji ichiramba ichifambira mberi, macircuit breaker pasina mubvunzo acharamba achichinja, zvichiwedzera basa rawo mukuchengetedza zvivakwa zvedu zvemagetsi.
