Macircuit Breakers: Vimbiso Yekuchengetedzwa Kwemagetsi

KunzwisisaMaputsi edunhu: Zvishandiso Zvakakosha Zvekuchengetedza MuMasisitimu Emagetsi

Munyika yeinjiniya yemagetsi nekuchengetedza, izwi rekuti "circuit breaker" rine zvarinoreva zvakawanda. Circuit breaker iswitch yemagetsi inongoerekana yagadzirwa kuchengetedza circuit yemagetsi kubva mukukuvadzwa kunokonzerwa nekuwanda kwemagetsi kana mashort circuit. Basa rayo guru nderekumisa kufamba kwemagetsi kana paine chikanganiso, nokudaro kudzivirira njodzi dzinogona kuitika dzakadai semoto wemagetsi kana kukuvara kwemidziyo. Chinyorwa chino chinoongorora zvakadzama zvinhu zvakasiyana-siyana zve circuit breakers, mhando dzadzo, mashandiro adzo, uye kukosha kwadzo mumagetsi emazuva ano.

Basa remuputsi wedunhu

Chinopwanya dunhu chinhu chakakosha pakuchengetedza dunhu remagetsi. Kana magetsi achipfuura nepakati pedunhu akatarwa, chinopwanya dunhu chinozviwisira chega, chichibvisa magetsi. Izvi zvakakosha kudzivirira kupisa zvakanyanya uye moto unogona kukonzerwa nemagetsi akawandisa. Kusiyana nemafusi, ayo anofanira kutsiviwa mushure mekunge aputika, ma circuit breakers anogona kudzoserwa patsva mushure mekunge agumburwa, zvichiita kuti ave sarudzo iri nyore uye inoshanda yekudzivirira dunhu.

Mhando dzemacircuit breakers

Kune mhando dzakawanda dzemacircuit breaker, imwe neimwe yakagadzirirwa mashandisirwo chaiwo uye nharaunda. Mhando dzakajairika dzinosanganisira:

1. Miniature Circuit Breaker (MCB): Aya macircuit breaker anoshandiswa mudzimba nemabhizimisi kudzivirira overload uye short circuits. MaMCB madiki uye anogona kuiswa nyore nyore muma distribution board.

2. Residual Current Circuit Breaker (RCCB): Midziyo iyi, inozivikanwawo seRCDs, yakagadzirirwa kudzivirira kuvhunduka kwemagetsi nekuona kusawirirana kwemagetsi. Kana paine chikanganiso chikaonekwa, RCCB inogumburwa, yobva yadzima magetsi.

3. Leakage Current Circuit Breaker (ELCB): Kufanana neRCCB, ELCB inoshandiswa kuona zvikanganiso zvepasi uye kudzivirira kuvhunduka kwemagetsi. Inonyanya kukosha munzvimbo dzine mvura, dzakadai sedzimba dzekugezera nenzvimbo dzekunze.

4. MaAir Circuit Breakers (ACB): Macircuit breakers aya anoshandiswa mumaindasitiri uye anogona kubata ma current ratings akakwira. MaACB akagadzirwa kuchengetedza masisitimu makuru emagetsi uye anogona kushandiswa nemaoko kana otomatiki.

5. MaHydraulic Magnetic Circuit Breakers: Aya macircuit breakers anoshandisa musanganiswa wekupisa nemagineti mechanisms kuvhura circuit. Anowanzo shandiswa mumagetsi makuru ane mafungu emvura akakwira.

Kukosha kweVapambi veDunhu muMagetsi Masisitimu

Kukosha kwemacircuit breaker hakufanirwe kutaurwa zvakanyanya. Anoita basa rakakosha mukuona kuchengetedzeka uye kuvimbika kwemasystem emagetsi. Nekudzivirira kuwandisa uye mashort circuit breaker, macircuit breaker haangobatsiri chete kuchengetedza michina yemagetsi, asiwo anobatsira kuchengetedza hupenyu hwevanhu vanogona kusangana nematambudziko emagetsi.

Pamusoro pekuchengetedzeka, macircuit breaker anobatsirawo kuvandudza kushanda zvakanaka kwemasystem emagetsi. Nekukurumidzira kubvisa macircuit breaker, macircuit breaker anogona kuderedza nguva yekushanda uye kuderedza njodzi yekukuvadzwa kwakanyanya kwezvivakwa zvemagetsi. Izvi zvakakosha zvikuru munzvimbo dzekutengeserana nemaindasitiri, uko magetsi asingadzoreki akakosha pakushanda.

Muchidimbu

Muchidimbu, macircuit breaker chikamu chakakosha chemagetsi emazuva ano. Kugona kwawo kumisa kufamba kwemagetsi otomatiki kana paine chikanganiso kwakakosha pakudzivirira vanhu nezvinhu. Kune mhando dzakasiyana dzemacircuit breaker, dzakakodzera kushandiswa kwakasiyana, saka kunzwisisa basa rawo nekukosha kwakakosha kune chero ani zvake ari kuita zveinjiniya yemagetsi kana kuchengetedzeka. Sezvo tekinoroji ichiramba ichifambira mberi, macircuit breaker pasina mubvunzo acharamba achichinja, zvichiwedzera basa rawo mukudzivirira magetsi edu.
