Mhando dzeCircuit Breaker neGwaro reSarudzo

Muminda yeinjiniya yemagetsi nekuchengetedza, izwi rekuti "circuit breaker" rinokosha zvikuru. Circuit breaker iswitch yemagetsi inongoerekana yagadzirwa kudzivirira macircuit kubva mukukuvadzwa kunokonzerwa nekuwanda kwemagetsi kana ma short circuit. Basa rayo guru nderekukanganisa magetsi kana paine chikanganiso, nokudaro kudzivirira njodzi dzinogona kuitika dzakadai semoto wemagetsi kana kukuvara kwemidziyo. Chinyorwa chino chichaongorora zvinhu zvakasiyana-siyana zve circuit breakers, kusanganisira mhando dzadzo, misimboti yekushanda, uye mashandisirwo adzo.

Mhando dzeMaputsi edunhu

Macircuit breaker anouya mumhando dzakasiyana-siyana, imwe neimwe yakagadzirirwa mashandisirwo chaiwo uye nharaunda. Mhando dzakajairika dzinosanganisira:

1. Madiki eChikamu Chinopwanya (MCB):Macircuit breaker aya anoshandiswa muzvivakwa zvekugara uye zvemabhizinesi kudzivirira kuwandisa kwemagetsi uye mashort circuit. MCB inongoerekana yadonha kana magetsi adarika kukosha kwakatarwa.
2. Chinopwanya Dunhu Remagetsi Rinosara (RCCB):Inozivikanwawo semudziyo wemagetsi unogara uripo (RCD), rudzi urwu rwecircuit breaker runodzivirira kuvhunduka kwemagetsi nekuona kusawirirana kwemagetsi. Kana paine chikanganiso chikaonekwa, RCCB inobvisa dunhu, nokudaro ichipa kuchengetedzeka kwakakosha.
3. MaMolded Case Circuit Breakers (MCCBs): Macircuit breakers aya anoshandiswa zvakanyanya mumaindasitiri uye anogona kutsungirira mafungu emvura akakwira. MaMCCB anopa dziviriro yekudzivirira zvikanganiso zvakanyanya, mapfupi, uye ground fault, zvichiita kuti akwanise kushandiswa mumagetsi akasiyana-siyana.
4. MaAir Circuit Breakers (ACBs): MaAir circuit breakers anowanzo shandiswa mumashandisirwo emagetsi ane simba guru uye anoshanda nekushandisa mhepo senzira yekudzima magetsi. Akakodzera kuiswa kwemagetsi makuru uye anogona kutsungirira mitoro yemagetsi yakakwira.
5. Muputsi weHydraulic-Magnetic Circuit: Rudzi urwu rwecircuit breaker runosanganisa ma hydraulic ne magnetic mechanisms kuti abvise macircuit. Nekuda kwekuvimbika kwayo uye kusimba kwayo, inowanzoshandiswa mumaindasitiri egungwa nendege.

Mashandiro azvinoita

Pfungwa yekushanda kwecircuit breaker iri nyore. Kana magetsi ari kufamba nemucircuit akadarika simba recircuit breaker, circuit breaker ichaona kusarongeka uku. Zvadaro, circuit breaker ichatanga kushanda, yobvisa circuit uye yokanganisa magetsi. Zvichienderana nerudzi rwecircuit breaker, chiito ichi chinogona kukonzerwa nekupisa, magineti, kana magetsi.

Semuenzaniso, mu miniature circuit breaker (MCB), bimetallic strip inogona kupisa zvakanyanya uye kukotama nekuda kwemagetsi akawandisa, zvichizopedzisira zvaita kuti switch iputsike. Kusiyana neizvi, residual current operated circuit breaker (RCCB) inoshandisa ma residual current current kuona zvikanganiso zvepasi kuti ione mamiriro ekutadza. RCCB dzinogona kuputsika mukati mema milliseconds, zvichideredza zvakanyanya njodzi yekuvhunduka kwemagetsi.

Kushandiswa kwema circuit breakers

Macircuit breaker chinhu chakakosha mumagetsi emazuva ano uye anoshandiswa zvakanyanya muzvikamu zvakasiyana-siyana. Munzvimbo dzekugara, macircuit breaker anodzivirira dzimba kubva kunjodzi dzemagetsi uye anovimbisa kuchengetedzeka kwevagari. Muzvivakwa zvemabhizinesi, macircuit breaker anotarisira mitoro yemagetsi, anodzivirira kudzimwa kwemagetsi, uye nokudaro anovandudza mashandiro emagetsi.

Munzvimbo dzemaindasitiri, macircuit breaker anodzivirira michina kubva mukukuvadzwa kunokonzerwa nemagetsi. Akakoshawo mumagetsi anowanikwazve akadai sema solar panels nema wind turbines, zvichidzivirira kushanduka-shanduka kwekugadzirwa kwemagetsi.

Chii chinonzi circuit breaker?

Chinopwanya dunhu mudziyo wekuchengetedza magetsi wakagadzirirwa kuchengetedza dunhu remagetsi kubva mukukuvadzwa kunokonzerwa nemagetsi anodarika ayo anogona kutakura michina zvakachengeteka (overcurrent). Basa rayo guru nderekumisa kuyerera kwemagetsi kudzivirira michina uye kudzivirira moto.

Muchidimbu

Muchidimbu, macircuit breaker chikamu chakakosha chemagetsi, ichiva nechokwadi chekuchengetedzeka uye ichidzivirira zvikanganiso zvemagetsi. Kune avo vanoshanda muinjiniya yemagetsi kana kuchengetedzeka, kunzwisisa mhando dzakasiyana dzemacircuit breaker, misimboti yekushanda kwayo, uye mashandisirwo ayo kwakakosha. Nekufambira mberi kwetekinoroji uye kuwedzera kwekushandiswa kwemagetsi, macircuit breaker pasina mubvunzo achaita basa guru mukuona kuvimbika uye kuchengetedzeka kwemasystem emagetsi. Ingave munzvimbo dzekugara, dzebhizinesi, kana dzemaindasitiri, kukosha kwemacircuit breaker hakugone kufuratirwa, zvichiita kuti zvive chikamu chakakosha chezvivakwa zvemagetsi zvemazuva ano.
