Zvidziviriro zveDunhu Rimwe Chete: Kuvandudza Kuchengetedzeka neKudzora Magetsi Munzvimbo Dzekugara neDzemabhizinesi

Maputsi edunhu rimwe chetezvinhu zvakakosha mumasisitimu emagetsi akagadzirirwa kuchengetedza maseketi nemidziyo yemagetsi kubva kumaseketi emagetsi akawandisa uye mapfupi. Iyi inzira yakakosha yekuchengetedza inobatsira kudzivirira moto wemagetsi nekukuvara kwemidziyo. Muchinyorwa chino, tichaongorora mashandiro, mhando, uye kukosha kwemaseketi emagetsi echikamu chimwe chete mumasisitimu emagetsi.

Mabasa e single phase circuit breaker

Basa guru remuchina wekupwanya magetsi wechikamu chimwe chete nderekumisa kufamba kwemagetsi mudunhu kana dunhu rapfuura miganhu yekushanda yakachengeteka. Kana dunhu rakanyanya kuwanda kana kuti dunhu pfupi rikaitika, muchina wekupwanya magetsi unozviputsira wega, wobva wadzima magetsi kudunhu rakakanganiswa. Izvi zvinobatsira kudzivirira kukuvara kwemidziyo yemagetsi newaya uye zvinoderedza njodzi dzemagetsi.

Mhando dzema "single phase circuit breakers"

Kune mhando dzakasiyana-siyana dzema "single-phase circuit breakers", imwe neimwe yakagadzirirwa kushandiswa kwayo uye voltage rating. Mhando dzakajairika dzinosanganisira ma "thermal-magnetic circuit breakers", ma "residual current circuit breakers" (RCCB) uye ma "miniature circuit breakers" (MCB).

1. Ma "circuit breakers" anodziya ne "thermal-magnetic": Aya ma "circuit breakers" anosanganisira "thermal-magnetic" inochengetedza "overcurrent" ne "short-circuit". Zvinhu zvinodziya zvinopindura kana zvakawandisa, nepo ma "magnetic" achipindura kana zvasvika ku "short circuit", zvichiita kuti zvikwanise kushandiswa zvakasiyana-siyana.

2. Residual Current Circuit Breaker (RCCB): RCCB yakagadzirirwa kudzivirira kubva pakubuda kwemvura kana kukanganisa kwenyika. Inotarisa kuenzana kwemagetsi aripo uye asina kusimba uye kugumburwa kana paine dambudziko, nokudaro kudzivirira kuvhunduka kwemagetsi uye njodzi dzemoto.

3. Miniature Circuit Breaker (MCB): MCB diki uye yakagadzirirwa kushandiswa mumagetsi ane voltage shoma. Dzinodzivirira overcurrent uye short-circuit uye dzinowanzo shandiswa mudzimba nemabhizimisi.

Kukosha kweVatambi veDunhu Rimwe Chete

Ma "single-phase circuit breakers" anoita basa rakakosha pakuona kuchengetedzeka uye kuvimbika kwesimba remagetsi. Heano mamwe ezvikonzero zvikuru nei achikosha:

1. Dzivirirai michina yemagetsi: Macircuit breaker anodzivirira michina yemagetsi nemidziyo kubva mukukuvadzwa kunokonzerwa ne overcurrent uye short circuit. Nekukanganisa kufamba kwemagetsi kana zvichidikanwa, anogona kudzivirira kugadzirisa kunodhura uye nguva yekushanda.

2. Kudzivirira moto: Kuwanda kwemagetsi ne short circuit zvinogona kukonzera moto wemagetsi. Macircuit breaker anobatsira kuderedza njodzi iyi nekukurumidzira kubvisa magetsi kana paine zvikanganiso, zvichidzivirira njodzi dzemoto.

3. Kuchengetedzeka Kwemunhu: MaRCCB anopa dziviriro kubva pakuvhunduka kwemagetsi kana paine dambudziko repasi kana kubuda kwemagetsi, izvo zvakakosha pakuona kuchengetedzeka kwemunhu munzvimbo dzekugara nedzekutengeserana.

Muchidimbu, ma "single-phase circuit breakers" chikamu chakakosha chemagetsi, achipa dziviriro yakakosha kubva pamagetsi anodarika mwero, ma "short circuit", uye zvikanganiso zvemagetsi. Kugona kwawo kuchengetedza michina yemagetsi, kudzivirira moto, uye kuona kuchengetedzeka kwemunhu kunoratidza kukosha kwawo mukuchengetedza kuvimbika uye kuvimbika kwekuisa magetsi. Zvakakosha kusarudza mhando chaiyo ye "circuit breaker" yekushandisa chaiyo uye kuve nechokwadi chekugadzirisa nekuyedza nguva dzose kuti irambe ichishanda zvakanaka mukudzivirira masisitimu emagetsi.
