Mhando dzeCircuit Breaker neGwaro reSarudzo

KunzwisisaMaputsi edunhu: Magamba Asingaimbirwi Ekuchengetedza Magetsi

Macircuit breaker anoita basa rakakosha pakuona kuchengetedzeka uye kushanda zvakanaka kwemasystem emagetsi. Midziyo iyi yakagadzirirwa kuchengetedza macircuit emagetsi kubva pakuzara kwemagetsi uye mashort circuit, nokudaro ichidzivirira njodzi dzinogona kuitika. Kunzwisisa mashandiro anoita macircuit breaker, mhando dzawo, uye kukosha kwawo kunogona kubatsira varidzi vedzimba nenyanzvi kuchengetedza nzvimbo yemagetsi yakachengeteka.

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 anoshanda sei?

Pfungwa yekushanda kwecircuit breaker iri nyore: inotarisa magetsi ari kufamba nemudunhu. Kana magetsi adarika muganho wakatarwa, circuit breaker inodonha, ichibvisa simba remagetsi. Izvi zvinodzivirira kupisa zvakanyanya uye moto unogona kuitika unokonzerwa nemagetsi akawandisa. Maitiro ari shure kweizvi anosanganisira zvinhu zvinonzwa kupisa kana magnetic-sensitive.

1. Ma "thermal circuit breakers": Midziyo iyi inoshandisa bimetallic strip inokotama kana yapiswa nemagetsi akawandisa, zvichizopedzisira zvakonzera switch, zvichityora circuit.

2. Magnetic circuit breaker: Iyi circuit breaker inoshanda ne electromagnet. Kana magetsi adarika muganho wakachengeteka, electromagnet inowedzerwa simba, ichidhonza lever kuti ivhure circuit.

Mamwe macircuit breaker emazuva ano anobatanidza mashandiro ekupisa uye emagineti kuti ape dziviriro yakawedzerwa uye kupindura kwakanaka.

Mhando dzemacircuit breakers

Kune mhando dzakasiyana dzemacircuit breaker, imwe neimwe iine chinangwa chayo:

1. Muchina wekupwanya dunhu (standard circuit breaker): Unowanikwa munzvimbo dzekugara, unoshandiswa kudzivirira kuputika kwemagetsi zvakanyanya uye mapfupi.

2. Ground Fault Circuit Interrupters (GFCI): Dzinokosha munzvimbo dzine mvura dzakadai sedzimba dzekugezera nekicheni sezvo dzichiona zvikanganiso zvepasi uye dzichidzivirira kurohwa nemagetsi.

3. Arc Fault Circuit Interrupter (AFCI): Yakagadzirwa kudzivirira moto wemagetsi unokonzerwa nezvikanganiso zvearc, maAFCI ari kudiwa zvakanyanya mudzimba itsva.

4. MaMinitary Circuit Breakers (MCBs): Aya anoshandiswa mukushandiswa kwemagetsi mashoma uye akanakira kuchengetedza dunhu rimwe chete.

5. MaResidual Current Circuit Breakers (RCCB): Midziyo iyi inoona kusarongeka kwemafambiro emagetsi uye inokosha mukudzivirira kuvhunduka kwemagetsi.

Kukosha kweVapambi veDunhu

Kukosha kwemacircuit breakers hakufanirwe kutaurwa zvakanyanya. Akakosha pa:

- Inodzivirira moto wemagetsi: Nekukanganisa kufamba kwemagetsi panguva yekuwanda kwemagetsi, macircuit breaker anoderedza zvakanyanya njodzi yemoto inokonzerwa nekupisa waya dzemagetsi.

- DZIVIRIRA MIDZIYO YAKO: Macircuit breaker anobatsira kuchengetedza michina yemagetsi neyemagetsi kubva mukukuvadzwa kunokonzerwa nekuwedzera kwemagetsi kana zvikanganiso.

- Kuchengetedzwa kwakawedzerwa: Kana paine chikanganiso, circuit breaker inogona kudzima magetsi nekukurumidza uye zvinobudirira kuchengetedza kuchengetedzeka kwevanhu nezvinhu.

- Kutevedzera Mutemo weMagetsi: Mitemo yakawanda yekuvaka inoda kuti pave nemacircuit breaker kuti pave nechokwadi chekuti mitemo yekuchengetedza yazadzikiswa.

Mutsetse Wekupedzisira

Muchidimbu, macircuit breaker chikamu chakakosha chemagetsi emazuva ano, achipa dziviriro yekutanga kubva pakuwanda kwemagetsi, ma short circuit, uye zvikanganiso zvemagetsi. Kugadziriswa kwadzo kunoita kuti dzive sarudzo inoshanda kune ese ari maviri ekugara uye ebhizinesi. Kunzwisisa mhando dzakasiyana dzema circuit breaker uye mashandiro adzo kunogona kubatsira vanhu kuita sarudzo dzakangwara dzekuchengetedza magetsi kumba uye kubasa. Sezvo tekinoroji ichifambira mberi, ma circuit breaker acharamba achichinja, zvichiwedzera basa rawo semagamba asina mukurumbira ekuchengetedza magetsi.
