Chinopwanya Dunhu Rinobuda: Vimbiso Yekushandisa Simba Rakachengeteka

KunzwisisaMaRCD Circuit Breakers: Gwaro Rakazara

Munyika yekuchengetedzwa kwemagetsi, maRCD circuit breakers (kana kuti maresidual current devices) anoita basa guru mukudzivirira vanhu nepfuma kubva kunjodzi dzemagetsi. Midziyo iyi yakagadzirirwa kuona kusawirirana kwemagetsi uye kubvisa simba remagetsi kana paine chikanganiso. Chinyorwa chino chinoongorora zvakadzama mashandiro, kukosha, uye kuiswa kwemaRCD circuit breakers, zvichipa kunzwisisa kwakazara kwekukosha kwawo mumagetsi emazuva ano.

Chii chinonzi RCD circuit breaker?

RCD circuit breaker mudziyo wemagetsi unogara uchitarisa magetsi ari mucircuit. Unoenzanisa magetsi ari kuyerera nepakati pewaya inopisa nemagetsi ari kuyerera nepakati pewaya isina kusimba. Mumamiriro ezvinhu akajairwa, magetsi maviri aya anofanira kunge akaenzana. Zvisinei, kana paine chikanganiso, senge short circuit kana munhu akabata waya inopisa netsaona, magetsi anodonhera pasi, zvichiita kuti pave nekusawirirana. RCD circuit breaker inoona musiyano uyu uye inovhura circuit nekukurumidza (kazhinji mukati me30 milliseconds), ichidzivirira kuvhunduka kwemagetsi uye ichideredza njodzi yemoto wemagetsi.

Mhando dzeRCD circuit breakers

Kune mhando dzakasiyana dzeRCD circuit breakers dzekusarudza kubva, imwe neimwe iine chinangwa chayo:

1. RCD Yakagadziriswa: Rudzi urwu rwemuchina rwunoiswa mukati meyuniti yemushandisi uye runodzivirira maseketi akawanda. Anowanzo shandiswa muzvivakwa zvekugara uye zvemabhizinesi.

2. Chidziviriro chekubuda kwemvura musokisi: Rudzi urwu rwechidziviriro chekubuda kwemvura rwunobatanidzwa musokisi yemagetsi chaiyo kuti ipe dziviriro kumidziyo yakabatirirwa mairi. Inonyanya kukodzera nzvimbo dzinoshandiswa midziyo yemagetsi kakawanda, senge mukicheni nekunze.

3. RCD inotakurika: Midziyo iyi inogona kuvharwa mune chero soketi yakajairika uye inopa dziviriro kumaturusi nemidziyo inoshandiswa munzvimbo dzakasiyana-siyana. Yakanakira nzvimbo dzekuvaka nemabasa ekunze.

4. Kusanganiswa kweRCD/MCB: Zvinosanganisa mashandiro eRCD neMinitary Circuit Breaker (MCB) muyuniti imwe chete, zvichipa dziviriro yekuwedzera simba uye dziviriro yekutadza kwenyika.

Kukosha kweRCD Circuit Breakers

Kukosha kwemaRCD circuit breakers hakufanirwe kutaurwa zvakanyanya. Akakosha pakusimudzira kuchengetedzeka kwemagetsi mudzimba, munzvimbo dzebasa, nenzvimbo dzeveruzhinji. Heano mamwe ezvikonzero zvikuru nei maRCD circuit breakers achikosha:

- Dziviriro kubva pakuvhunduka kwemagetsi: MaRCD anoderedza zvakanyanya njodzi yekuvhunduka kwemagetsi, izvo zvinogona kuisa hupenyu panjodzi. Anonyanya kukosha munzvimbo dzakanyorova dzakadai sedzimba dzekugezera nemakicheni, uko njodzi yekusangana newaya dzinorarama netsaona yakanyanya.

- Dziviriro pamoto: Kukanganisa kwemagetsi kunogona kukonzera moto, uye maRCD anogona kubatsira kuderedza njodzi iyi nekudzima magetsi asati awedzera kukanganisa.

- Tevedzerai mitemo: Nyika zhinji dzine mitemo inoda kuti maRCD aiswe panguva yekuvaka kutsva uye kugadzirisa magetsi. Kutevedzera mitemo iyi hakungovimbisi chete kuchengetedzeka asiwo kunodzivirira varidzi vepfuma kubva pamhosva dzemutemo.

Kuisa uye Kugadzirisa

Kuiswa kwemaRCD circuit breakers kunofanira kugara kuchiitwa nenyanzvi yemagetsi ine hunyanzvi kuitira kuti ive nechokwadi chekuti mitemo yemagetsi yemuno inotevedzera mitemo nemitemo. Nyanzvi yemagetsi ichaongorora sisitimu yemagetsi, yoona mhando yakakodzera yeRCD, uye yoiisa panzvimbo chaiyo.

Kana yaiswa, RCD inofanira kuongororwa nguva nenguva kuti ive nechokwadi chekuti iri kushanda nemazvo. Mazhinji maRCD ane bhatani rekuyedza rinofanira kudzvanywa kamwe chete pamwedzi kuti vaone kana mudziyo uri kushanda nemazvo. Kana RCD ikasadonha kana bhatani rekuyedza radzvanywa, ingangoda kutsiviwa.

Muchidimbu

MaRCD circuit breakers chikamu chakakosha chemagetsi ekuchengetedza. Kugona kwawo kuona nekukurumidza uye kupindura zvikanganiso zvemagetsi kunoita kuti zvive zvakakosha mukudzivirira kuvhunduka kwemagetsi nemoto. Sezvo tekinoroji ichifambira mberi uye masisitimu emagetsi achiwedzera kuoma, basa reRCD circuit breakers richaramba richichinja, kuona kuti kuchengetedzeka kunoramba kuri chinhu chakakosha mudzimba dzedu nenzvimbo dzebasa. Kuisa mari muRCD circuit breakers kunopfuura chinodiwa chemutemo; kuzvipira kuchengetedza hupenyu nepfuma kubva kunjodzi dzemagetsi.
