Kuyini RCD

Ngaphandle kuwulwazi lwalokho RCD (asalile kudivayisi lamanje), ukuqinisekisa ukusebenza okuphephile zikagesi kunzima. Ngokuvamile, uyakwazi ukuzwa izindaba mayelana ukuwasha machine indlela serviceable ngogesi lapho wathinta ngesikhatsi kokuhlinzwa. Kwenzeka okufanayo uma ngesikhathi esifanayo uthinte umzimba ukusebenza ikhompyutha futhi radiators. Lesi simo esiyingqayizivele sibangelwa enza khona, futhi akuyona ukungasebenzi, kodwa kunalokho isici imishini kagesi ngaphandle isisekelo.

Ngokuphawulekayo kwandisa kagesi avumela RCD.

Kuyini RCD? Le divayisi wesifunda full ngesivinini, ogxile Ngokuqhathanisa imisinga ezihambisana umthwalo bese uya emuva inethiwekhi, enza circuit evulekile lapho ukungalingani (umehluko wamanje livela). Okusho ukuthi, uma endaweni ethile esigabeni evikelwe komugqa is avuzayo emhlabathini, idivayisi kuthola futhi uyeke lingakunika amandla umugqa.

Cabangela isimiso RCD. Inhliziyo idivayisi kuyinto transformer zamanje, obizwa nangokuthi umehluko. Siqukethe Windings ezintathu: oyinhloko (L1) kanye yesibili (L2), ngokulandelana, kufakwe unokungaxhumani isigaba futhi izintambo hlangothi, kanti eyesithathu (L3) ixhunywe inhlamvu indlela. Kuye indlela ukubulawa kungenziwa unikezwe okusezingeni uzwela edluliselwe (RCD uhlobo electromechanical) noma zikagesi, ngokuvamile comparator ne-amplifier (E-hlobo). Le ndlela yokwenza inhlamvu is athutha oluhambisana kuya ashukumisa drive namandla ikhefu oxhumana.

Lapho umthwalo ixhunywe RCD ngokusebenzisa emazombezombe L1 futhi L2, a notshwala zamanje. Kusukela ngo-operation evamile ukubaluleka wamanje enikeziwe kumthengi Ikhipha alinganayo ke ecucuza zabo Imininingwane kazibuthe ngabasebinzisi neutralized futhi oholayo (the Windings abasondelene, zamanje iqondiswa oppositely). Ngenxa yalokho, i-L3 ikhoyili ayikhona umphumela. Mode wokusebenza kakhulu ekushintsheni ngesikhathi esifanayo ngokuthinta umzimba womuntu emhlabathini futhi ezilimele iyunithi ngaphansi voltage. Kulokhu, umqhubi isigaba (L1 emazombezombe) i zamanje ezengeziwe kokweqa zamanje emazombezombe L2. Eqinisweni, kukhona umehluko, ngenxa samanje angena wesifunda isigaba umqhubi, kuzoya phansi ngokusebenzisa umuntu, futhi ababuyelanga RCD. Yokucucuza kazibuthe idlula ikhoyili uhlawula L1 L2 ukugeleza isinyathelo, ngokulandelana, eyenziwe yokucucuza kazibuthe kudala L3 emazombezombe encane zamanje ukwanele ukusebenza kwe-edluliselwe noma busebenze ngogesi kanye actuation we actuator ngokwephula oxhumana amandla.

Umuntu uyazi ukuthi RCD, uyakwazi ngempela ukwenza isheke elula kokusebenza kwalo. On uma RCDs ukwethula inkinobho "Test", ngokuchofoza okuyinto ungakwazi ukuhlola ukusebenza zedivayisi. Ukucindezela kafushane shunts omunye Windings, balisusa nasezinguqulweni circuit eyenziwe isinxephezelo ecucuza kazibuthe, ngakho idivayisi kucushwa.

Kuphakama umbuzo omuhle - indlela ukuxhuma RCD? Idivayisi kufanele ukukhwezwa esihambisana ngesishintshi othomathikhi, ngoba ayiqukethe ukukhishwa ezishisayo kanye kagesi, ngokulandelana, akusho ukuvikela sindisa (ezishisayo) kanye ephezulu zamanje isekhethi (SC). Fault zamanje kungalimaza RCD, njengoba kule modi wokusebenza ukuvuza ingekho, kodwa Inani lamanje luyanda izindinganiso eziphakeme kakhulu. By endleleni, lokhu kungani kubalulekile ukukhetha lapho ukuthenga isitokwe nge RCD ukalwe zamanje. Ngokwesibonelo, uma umshini senzelwe 16 Amp, le RCD akumelwe ibe ngaphansi kuka 25 amperes. Ngamagama alula, lamanje ukalwe we RCD - elamanje kuvumelekile izingxenye babashayeli yayo.

Ngokusobala, esikhathini sethu, kuyasiza hhayi kuphela ukuqonda umbuzo, uyini RCD, kodwa futhi bakwazi ukuyisebenzisa ekhaya lakho siqu. Phela, lokhu kuyinto ukuphepha okwengeziwe kuwo wonke amalungu omndeni.
