Indlela yokuxhuma i-RCD efulethini

Ngenxa yokwethulwa kancane kancane kwezobuchwepheshe baseYurophu ezweni lethu, izitolo zaqala ukuhlinzeka ngemishini eminingi kagesi. Abanye babo bathola i-niche yabo ngokushesha, kanti abanye bayanyamalala masinya, babhekene nezici zomqondo womuntu. Namuhla sizobuka indlela yokuxhuma i-RCD ngokufanele. Lawa madivaysi ayithandwa kuphela, kodwa nawo afakwe ku-PUE - incwadi yedesk for electrician ngamunye. Naphezu kokubonakala okulula kokuxhumana, sincoma kakhulu ukuthi labo bantu abangenayo imfundo efanele, basebenzise izinsizakalo, futhi bazame ukuxazulula le nkinga ngokwabo. Udinga ukwazi ukuthi isisekelo sendlela yokuxhuma i-RCD.

Ukuphepha

Igama elivamile elithi "RCD" kufanele liqondwe ngokuthi "idivayisi yokuvimbela yokuzivikela". Le divayisi iklanyelwe ukunciphisa amashumi ezinkinga ingozi yokugesi kagesi uma kwenzeka ukungasebenzi kahle ngogesi noma izinto zikagesi. Isimiso sokusebenza kwayo siyinto elula kakhulu: kukhona ukuqhathaniswa kwamagagasi emigqeni emibili: engenayo kumthengi futhi angena ku-wiring yangaphandle. Phakathi kwabo, ukulingana kufanele kuhlonishwe. Uma kukhona umehluko (ukuvuza), kuvele ukuvalwa. Ngamanye amazwi, uma, isibonelo, ukushisa komshini wokushisa kagesi kuwonakele,

Futhi amanzi azoba ngaphansi kwengozi eyingozi, i-RCD izokwehlisa ukuvuza ku "emhlabathini", unqamule isifunda futhi uvimbele usizi olungenzeka. Yiqiniso, ukulahlekelwa okuthile okuvunyelwe kuyamukeleka, okumele kucatshangelwe uma ukhetha amanani aqokiwe edivaysi. Nokho, ukuze isifunda sisebenze, kubalulekile ukuqonda ukuthi ungaxhuma kanjani i-RCD.

Indawo yokufaka

Indawo yale divayisi incike ekutheni iyiphi ingxenye yesifunda ilungele ukuvikelwa. Uma kungumbuzo wokufaka yonke indlu, khona-ke amakhosi awazi ukuxhuma i-RCD ngokuvamile anikela isihlangu eduze kwemitha - i-counter. Lokhu kungcono kunazo zonke, ngoba kule ndawo kuyisiqalo se-wra yendawo yokuhlala. Kodwa uma ufuna ukuvikela uhlelo lokusebenza oluthile kagesi, kufanele uqale ukhethe indawo elula eduze nayo, lapho ubeka khona ibhokisi-isisekelo. Ngaphezu kwalokho, kuyadingeka ukwenza ukukhishwa okudingekile ngokuya kuhlelo. Kulesi sihloko ngeke sicabange ngezici ezikhethekile zalezi zixazululo, lolu lwazi lungatholakala kalula emithonjeni ekhethekile.

Indlela yokuxhuma i-RCD

Sicela uqaphele ukuthi idivaysi elula yokuhamba kanye ne-breaker circuit kukhona izinto ezimbili ezihlukene. Isibonelo, uma kwenzeke ukuthi kwenzeke phakathi kwesikhashana esifundeni esifundeni esixhunywe kudivayisi, i-RCD ngeke ixhumeke, ngoba inani lamagagasi abahamba phambili lizolingana (inani, njengoba ubona, lingalawulwa). Ngakho, into ebaluleke kakhulu ukuxhuma isifunda se-RCD. Okusho ukuthi, kuyasiza ukuthi udwebe okokuqala, ukuthi uzokwenyuka kanjani futhi kuphi. I-RCD ihlale ifakwe ngemuva komshini, futhi okwamanje umkhawulo wokugcina walezi zinsuku akumele ube mkhulu kunalokho kudivayisi evikelayo embuzweni. Okuhlukile yi-differential automata ehlanganisa amadivayisi womabili kuphakheji elilodwa.

I-terminal terminals ye-RCD inezimpawu ezihambelana ezibonisa ukuthi isigaba kufanele sixhunywe kuphi, futhi kuphi - i-zero conductor (N). Emigqeni ephumayo, lo myalelo awuwona umgomo. Uma umqhubi womhlabathi ehlinzekwa ngumbambo, ngeke uqale ku-RCD. Ekusetshenzisweni kwedivayisi akanayo umphumela. Ake sibone: azikho izici "ezifihliwe" ekuxhumaneni. Ngenethiwekhi yocingo emibili, oxhumana nabo abangu-4 bahilelekile: isigaba naso zendlela, futhi 2 ngomthwalo (umzila ophumayo).
