Sitshele RCD: lokho kusho ukuthini futhi kusebenza kanjani

Kule nkathi yobuchwepheshe okusezingeni eliphezulu abantu sizungezwe lenqwaba amadivayisi futhi imishini, ukusebenza ngosizo ugesi. Futhi mkhulu inombolo, aba maningi amathuba okuba umuntu abanjwe ugesi. Ukuze ugweme lokhu, kusungulwe RCD. Kuyini futhi kungani udinga ukuba, sichaza ngokuningiliziwe kulesi sihloko.

aphoyintimenti

Kudivayisi (RCD) yakhelwe Ukuvikelwa umehluko umuntu shock ngogesi lapho othinta izindlu kagesi (yasendlini zikagesi), owawuvela nginomdlandla lapho iphutha ukwahlukanisa.

Lapho RCD kwabangela

Siyaqhubeka indaba RCD. Lokho kusho ukuthini futhi kusebenza kanjani? Ngemva umuntu othinta ngaphansi kwamandla lisebenze ezezindlu, i kagesi iqala umongozima. Lapho isifinyelele ukubaluleka 30 ma, lo ezithothene RCD kwenzeka. Ngenxa yalokho, lo voltage ngokuzenzakalelayo ixhumeke kumsindo imishini obonakele. Lo muntu akanayo okuzwayo njengoba emizweni ubuhlungu kwenzeke imisinga okuningi ephakeme (50 ma). Ebulalayo abantu kuyinto samanje 100 ma.

Yini liqukethe RCD

Asalayo zamanje wesifunda full kuhlanganisa a transformer wamanje, uhlelo actuator (edluliselwe uhlelo kanye iziyisikhombisa ukuphulwa), i-self-test busebenze. kumadivayisi angeziwe eyinkimbinkimbi eziqukethe isakhiwo sabo futhi system of kagesi ephambene ukubaluleka wamanje cutoff (isivikelo isekhethi imisinga kanye overload).

Isimiso ezisebenza we RCD

Kuyini lokhu? Kanjani kule divayisi icushiwe? Manje thina sitshele ngalokhu ngemininingwane yakhona. Ukusebenza RCD wabeka transformer Umgomo we operation wamanje (DC). ukudlula Isigaba nokusebenza babashayeli ngokusebenzisa zero transformer zamanje. Ngezinye evamile imishini yokusebenza (nge ukwahlukanisa yayinjalo) ukubaluleka imisinga eligeleza kuwo bayalingana ezidlula kodwa obuhlukile isiqondiso. Ngenxa yalokho, baba ephumelela ukwenza ecucuza kazibuthe e emazombezombe we CT, okuyinto ayafana e ezidlula kodwa obuhlukile isiqondiso ukuthi ukhansele ngokuphelele nomunye (phezu CT yesibili semikhawulweni emazombezombe ka kungekho voltage). Lapho i ukwahlukanisa imishini iphutha ingxenye zamanje isigaba umqhubi avuzayo endaweni ngokusebenzisa umqhubi isisekelo (lapho izindlu lihlala) noma yimuphi umuntu ngokuthinta kule lisebenze. Ngenxa yalokho, inani lamanje ogeleza umqhubi hlangothi, iba lincane isigaba ukuhamba. Lokhu kuholela yokuthi le fluxes magnetic transformer emazombezombe zihlukile ezidlula. Ngenxa yalokho, kube semikhawulweni CT voltage livela. Ngemva edluliselwe exhunywe kubo, zamanje uqala ukugeleza. Lapho ufika ohlangothini kuya ku-30 ma, bahlabe umkhosi, ashukumisa iziyisikhombisa breaking uhlelo. Imishini sivaliwe.

Iinthombe RCD

Kuyinto kuphela emva ukuhlonza nokuxazulula inkinga zikagesi, okwaholela nokucupha zedivayisi ngokucindezela iziyisikhombisa cocking.

isiphetho

Kulesi sihloko, sathula wena imininingwane ne RCD: ukuthi kuyini, ukuthi isebenza kanjani nokuthi yini isetshenziswa. Sithemba lolu lwazi libe lusizo kakhulu kuwe.
