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 uye ma short circuit senzira yekudzivirira 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 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 agumburwa, zvichiita kuti ave sarudzo iri nyore uye inoshanda yekudzivirira circuit.
Macircuit breaker anoshanda sei?
Pfungwa yekushanda kwemacircuit breaker iri nyore: anotarisa magetsi ari kufamba nemudunhu. Kana magetsi adarika muganho wakatarwa, circuit breaker inodonha, ichibvisa simba. Izvi zvinodzivirira kupisa zvakanyanya uye moto unogona kukonzerwa nemagetsi akawandisa. Maitiro acho anowanzo sanganisira thermal trip kana magnetic trip system.
- Ma "thermal circuit breakers": Aya ma "circuit breakers" anoshandisa bimetallic strip inokotama kana yapiswa nemagetsi akawandisa, zvichizopedzisira zvaita kuti switch ivhure circuit.
- Ma "electromagnetic circuit breakers": Aya ma "circuit breakers" anobata kukwira kwemagetsi kamwe kamwe, senge kunokonzerwa ne "short circuit". Anoshandisa "electromagnet" kudhonza "lever", achipwanya circuit ipapo ipapo.
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 dzichigona kuona zvikanganiso zvepasi uye kudzivirira kurohwa nemagetsi.
3. Arc Fault Circuit Interrupters (AFCI): Yakagadzirwa kudzivirira moto wemagetsi unokonzerwa nezvikanganiso zvearc, macircuit breaker aya ari kuwedzera kufarirwa mudzimba dzemazuva ano.
4. Miniature Circuit Breaker (MCB): Inoshandiswa mukushandiswa kwemagetsi mashoma uye inodzivirira overload.
5. Residual Current Circuit Breaker (RCCB): Inoona kusawirirana kwemagetsi uye inokosha mukudzivirira kuvhunduka kwemagetsi.
Kukosha kweVapambi veDunhu
Kukosha kwemacircuit breakers hakufanirwe kutaurwa zvakanyanya. Akakosha pa:
- Kuchengetedzeka: Macircuit breaker anodzivirira hupenyu nepfuma nekudzivirira moto wemagetsi uye kuvhunduka kwemagetsi.
- ZVAKANYANYA KUKOSHA: Kusiyana nemafuyusi anoda kutsiviwa, macircuit breaker anogona kudzoserwa patsva zviri nyore, zvichideredza nguva yekushanda.
- Inochengetedza mari: Kunyange hazvo mari yekutanga ichigona kunge yakakwira kupfuura mafiyuzi, macircuit breaker anochengetedza mari kwenguva refu nekuti anoderedza njodzi yekukuvadzwa kwemagetsi uye kudiwa kwekuchinjwa nguva nenguva.
- Kutevedzera mitemo: Mitemo yakawanda yekuvaka inoda kuti pave nemacircuit breaker, kunyanya GFCI neAFCI, kuitira kuti mitemo yekuchengetedza itevedzwe.
Mutsetse Wekupedzisira
Muchidimbu, macircuit breaker chikamu chakakosha chemagetsi emazuva ano, achipa dziviriro yekutanga kubva pakuremerwa zvakanyanya uye mashort circuit. Anogona kugadziriswazve mushure mekugumburwa, zvichiita kuti ave sarudzo inoshanda kune ese ari maviri ekugara uye ebhizinesi. Kunzwisisa mhando dzakasiyana dzemacircuit breaker uye mashandiro awo kunobvumira vanhu kuita sarudzo dzakangwara maererano nekuchengetedzeka kwemagetsi mudzimba dzavo nenzvimbo dzebasa. Sezvo tekinoroji ichifambira mberi, macircuit breaker acharamba achichinja, zvichiwedzera basa ravo semagamba asina mukurumbira ekuchengetedza magetsi.
