Kuongororwa kweResidual Current Circuit Breakers neOverload Protection

Munyaya dzekuchengetedzwa kwemagetsi,maResidual current circuit breakers (RCBs) ane dziviriro yakawandisazvishandiso zvakakosha pakudzivirira vanhu nepfuma kubva kunjodzi dzemagetsi. Chinyorwa chino chinotarisa mabasa, zvakanakira, uye mashandisirwo emaRCB, zvichiratidza kukosha kwawo mumagetsi emazuva ano.

A chinodzora dunhu remasara (RCB), inozivikanwawo semudziyo wezvino wasara (RCD), yakagadzirirwa kuona kusawirirana kwemagetsi. Kana ikaona kuti magetsi ari kuyerera nepawaya iri mhenyu uye waya isina kusimba haina kuenzana, zvinoratidza kuti magetsi anogona kubuda, izvo zvinogona kukonzera kuvhunduka kwemagetsi kana njodzi dzemoto. RCB inokurumidza kugumburwa nekudzima circuit kudzivirira tsaona.

Basa rekudzivirira zvinhu zvakawandisa

Panguva iyomaResidual current circuit breakers (RCBs)Zvakakosha pakuona kubuda kwemvura, hazvigone kudzivirira kuwanda kwemvura—ndiko kuti, mafungu emvura anodarika simba redunhu. Apa ndipo panopinda dziviriro yekuwanda kwemvura. MaRCB ane dziviriro yekuwanda kwemvura anobatanidza mabasa emaRCB nemacircuit breakers, zvichipa kuchengetedzeka kwakakwana.

Kudzivirira kuwanda kwemagetsi kunoshanda nekutarisa magetsi ari kufamba mudunhu. Kana magetsi akadarika chiyero chakatarwa mukati menguva yakatarwa, mudziyo uchagumburwa wodzima magetsi. Basa iri rinoita kuti magetsi akwanise kudzivirira kubuda kwemagetsi nekuwanda kwemagetsi, nokudaro zvichideredza zvakanyanya njodzi yemoto wemagetsi nekukuvadzwa kwemidziyo.

Zvakanakira kushandisa ma residual current operated circuit breakers ane dziviriro ye overload

1. Kuchengetedzwa Kwakawedzerwa:Chinhu chikuru chinobatsira pakushandisa ma residual current operated circuit breakers (RCBs) ane dziviriro yakawandisa ndechekuti akachengeteka zvakanyanya. Midziyo iyi inogona kuona kubuda kwemvura uye kuwanda kwemvura, zvichideredza njodzi yekupiswa nemagetsi, zvichiita kuti zvive zvakakosha munzvimbo dzekugara, dzekutengeserana, uye dzemaindasitiri.
2. Kudzivirira Midziyo: Kuwanda kwezvinhu kunogona kukonzera kuti michina yemagetsi nemichina iwedzere kupisa uye ikanganiswe. MaResidual current operated circuit breakers (RCBs) ane dziviriro yekuwedzera zvinhu anobatsira kudzivirira izvi, nokudaro achiwedzera hupenyu hwemichina uye kuderedza mari yekugadzirisa.
3. Kutevedzera Mutemo: Mitemo yakawanda yekuchengetedza magetsi inoda kuti pave nemaRCB (residual current operated circuit breakers) aiswe mune mamwe mashandisirwo. Kushandisa RCB ine dziviriro yakawanda kunovimbisa kutevedzera mitemo iyi, zvichipa varidzi vedzimba nevanoita mabhizinesi rugare rwepfungwa.
4. Dhizaini iri nyore kushandisa: MaRCB emazuva ano ane dziviriro yekuwedzera simba akagadzirwa kuti zvive nyore kushandisa. Anowanzo shongedzwa nebhatani rekugadzirisa magetsi uye mwenje wekuratidza kuti magetsi anomhanya zvakanaka, zvichiita kuti vashandisi vakwanise kuona matambudziko nekukurumidza uye kudzoreredza simba pasina rubatsiro rwenyanzvi.

Mashandisirwo eResidual Current Circuit Breakers ane Overload Protection

MaResidual current operated circuit breakers (RCBs) ane dziviriro yekudarika simba anoshandiswa muzvinhu zvakasiyana-siyana akakodzera kushandiswa kwakasiyana-siyana. Munzvimbo dzekugara, anowanzo shandiswa munzvimbo dzine njodzi huru dzakadai sekicheni, dzimba dzekugezera, uye panze. Munzvimbo dzekutengeserana nemaindasitiri, zvishandiso izvi zvinodzivirira michina, maturusi, uye michina yemagetsi yakanyatsogadzirwa kubva mukukuvadzwa kunokonzerwa nekuwanda kwemagetsi uye zvikanganiso zvemagetsi.

Pamusoro pezvo, maResidual current operated circuit breakers (RCBs) ari kuwedzera kubatanidzwa mumagetsi anodzokororwa, akadai semagetsi ezuva, izvo zvinobatsira kudzivirira kutadza kunokonzerwa nekuchinja-chinja kwesimba rinobuda.

Ko RCD ine dziviriro yekuwedzera zvinhu here?

RCD yakachena ichaona kusawirirana muma currents e supply ne return conductors e circuit. Asi haigone kudzivirira kubva pakuzara kana kupfupika sezvinoita fuse kana miniature circuit breaker (MCB) (kunze kwenyaya yakakosha ye short circuit kubva pamutsetse kuenda pasi, kwete line kuenda kune neutral).

Muchidimbu

MaResidual current circuit breakers (RCCBs) ane dziviriro yekuwedzera simba zvinhu zvakakosha mumagetsi emazuva ano.Midziyo iyi inobatanidza kuona kubuda kwemvura uye dziviriro yehuwandu hwemagetsi, kusimbisa kuchengetedzeka, kudzivirira michina, uye kuona kuti mitemo yemagetsi inotevedzwa. Sezvo tekinoroji ichiramba ichifambira mberi, kukosha kweRCCBs mukuchengetedza hupenyu nepfuma kuchawedzera, zvichiita kuti ive mari yakawanda mukuisa magetsi. Ingave munzvimbo dzekugara, dzekutengeserana, kana dzemaindasitiri, kuisa maRCCBs ane dziviriro yehuwandu hwemagetsi idanho rekugadzirira ramangwana remagetsi rakachengeteka.
