Yintoni i RCD

Ngaphandle ulwazi oko RCD (isixhobo eyintsalela current), ukuqinisekisa ukusebenza ngokhuselekileyo izixhobo zombane kunzima. Wena uyakwazi ukuva amabali malunga kumatshini wokuhlamba ukuba ziyalungiswa ungakubhabhisa nombane xa wachukumisa ngexesha lomsebenzi. Into efanayo xa ngaxeshanye bachukumise umzimba computer ukusebenza kunye radiators. Le meko likhona, kwaye sibangelwa, kodwa kunokuba uphawu lwe izixhobo zombane ngaphandle nozinzo.

Ngokuphawulekayo kwandisa yombane ukuvumela RCD.

Yintoni i RCD? Esi sixhobo ngesantya esiphezulu ndingumgqithi wesiphaluka, nto leyo esekelwe ngokuthelekisa imisinga ezihambelana umthwalo esiya womnatha, enza wesiphaluka oluvulelekileyo xa ukungalingani (ezohlukileyo yangoku livela). Oko kukuthi, ukuba ethile kwicandelo ezikhuselweyo selayini ayivuzi na emhlabeni, ifowuni ibhaqa waza de-amandla umgca.

Cinga kumthetho RCD. Intliziyo isixhobo a sombane ngoku, ekwabizwa ngokuba umehluko. It iqulathe engathi ezintathu: lokuqala (L1) kunye lwesibini (L2), ngokulandelelanayo, iqukwe discontinuities kwisigaba kunye iingcingo cala, kwaye eyesithathu (L3) iqhagamshelaniswe indlela ezibanga. Kuxhomekeka kwindlela uphumezo i inganikezelwa nangovakalelo relay ophezulu (RCD Uhlobo electromechanical) okanye amacandelo elektroniki, ngokokuqhelekileyo a comparator kunye msindo (E-type). Le ndlela kubangela ukuba zoomatshini kukhatshwa ukuya mawahlaziyeke drive waphule namandla abafowunelwa.

Xa umthwalo liqhagamshelene RCD nge ngokubhijela L1 kunye L2, uhamba yangoku. Ekubeni ukusebenza eqhelekileyo ixabiso yangoku anikiwe umsebenzisi Ukuphama olulinganayo, ngoko ngobhobhozo sabo setotali ngemagnethi esabangela ukuba bangabi kwaye ngunothi (i engathi zikufutshane, yangoku ngqo oppositely). Ngenxa yoko, le L3 coil ayikho nasonasiphi na isiphumo. Indlela yokusebenza kakhulu nokutshintsha ngaxeshanye uchukumisa umzimba womntu phantsi nawezonakeleyo iyunithi phantsi ombane. Kulo mzekelo, umbhexeshi isigaba (L1 ngokubhijela) umsinga ezongezelelweyo elingaphezu L2 jiko yangoku. Enyanisweni, kukho umahluko, ngenxa yangoku bajikeleze kwesigaba Umqhubi, kuya kungena emhlabeni usebenzisa umntu, kwaye babuyela RCD. Wobhobhozayo Imagnethi idlula UKUBUYISELA coil L1 L2 flow inyathelo, ngokulandelelana, eyenziwe wobhobhozayo magnetic kudala L3 oyinkampani encinane yangoku ezaneleyo ukuze nokusebenza relay okanye busebenze ngekhompyutha kunye actuation le actuator ngokwaphula abafowunelwa ngamandla.

Umntu owaziyo ukuba RCD, ngokuqinisekileyo uyakwazi ukwenza indlela itsheki elula yokusebenza kwayo. Ngomhla kwimeko naziphi RCDs uyisondeze iqhosha "Uvavanyo", ngokunqakraza kwi apho ungavavanya ukusebenza kwefowuni. Ngokucofa ngokufutshane shunts enye engathi, ukusisusa ukusuka wesekethe eyenziwe imbuyekezo ukubhobhoza magnetic, ngoko ifowuni kwavusa.

A umbuzo enobulungisa - ukuqhagamshela indlela RCD? Isixhobo ukuba mayixhonywe ngokubambisana kunye ukuzitshintshela, kuba akukho nto ibe kukhupho thermal yaye umoya, ngokulandelelana, akuthethi ukukhusela ngokuchasene ukucima kombane (thermal) kunye ophezulu-yangoku elifutshane-yesekethe (SC). Iphutha zangoku kungonakalisa RCD, njengoko kule ndlela yokusebenza ye ukuvuza lungenzeki, kodwa ixabiso yangoku inyuswe ukuya amaxabiso aphezulu kakhulu. Hi ndlela leyi, le nto kubalulekile ukuba ukhethe xa uthenga impahla kunye RCD rated lwangoku. Umzekelo, ukuba umatshini senzelwe 16 Amp, i-RCD kufuneka ungabi ngaphantsi kwe amperes-25. Ngamagama alula, i yangoku rated lo RCD - iyasetyenziswa na kuvumelekile ukuba amacandelo ababhexeshi yayo.

Ngokucacileyo, kwixesha lethu, kubalulekile nje ukuqonda lo mbuzo, yintoni na RCD, kodwa kwakhona bakwazi ukulusebenzisa kwikhaya lakho. Ngapha koko, lo ukhuseleko abongezelelweyo ukulungiselela onke amalungu entsapho.
