Eziphuthumayo wesifunda amadlambi noma RCD. I RCD kudivayisi. Ixhuma wesifunda amadlambi eziphuthumayo

Ikhaya ngogesi - kuyinto nesihloko eziyinkimbinkimbi futhi ezihlukahlukene, futhi kuyinto efiselekayo ukwazi imininingwane eyisisekelo umninindlu ngamunye, njengoba kuthinta hhayi kuphela izindleko zezimali kodwa ukuphepha ekhaya lakho. Kulesi sihloko sizozama ukuthola okuyinto engcono - Emergency amadlambi wesifunda noma RCD.

Isingeniso nendaba, noma, iyini amadlambi eziphuthumayo wesifunda?

Ukuze kubhekwane kahle nalesi simo, kuqala zama ukuchaza nemiqondo eyisisekelo. Ngakho, Emergency wesifunda oluseduze.

Idivayisi, ngokuthi umshini umehluko, ngempumelelo ihlanganisa imisebenzi kokubili RCD kanye ezivamile wesifunda full. Lokhu full ivikela umuntu oxhumana naye we izingxenye wadalula ye conductive wire ingxenye noma kulezo zingxenye inethiwekhi kagesi, okuyinto sicindezelekile ngenxa umonakalo wiring noma ezinye izici ezifanayo. Namuhla, kunamabandla amaningi kakhulu lezi zinto, okuyinto zenzelwe njengoba ehlukene yokusebenza imisinga kanye ezahlukene ukuvuza imisinga.

Sici Its main esiwuphawu ukuthi siqukethe kahle ahlukaniswe izingxenye ezimbili obusebenzayo: circuit-full (ngoba izigxobo ezimbili noma ezine), kanye module isivikelo abanjwe ugesi. Ukufakwa eziphuthumayo wesifunda amadlambi kufanele kwenziwe kuphela obandayo Din-wesitimela, nge ilungiselelo elinjalo oluthatha indawo ingasaphathwa, kunokuba nhlanganisela RCD nowesifunda full.

Sikhishwe isikhathi kahle, okuyinto imizuzwana 0.04 kuphela, esiphezulu imishini umehluko ukunikeza ukuvikeleka okwenele ugesi abantu cishe kunoma yimiphi imibandela yokusebenza. Kubalulekile futhi ukuthi umehluko othomathikhi qualitatively ukuvikela imishini inethiwekhi kusukela sindisa, okuyinto nakanjani ziphakame zonke izinhlobo eziphuthumayo. Futhi omunye. Ukwakheka linikeza kungenzeka amandla Take-off ngaphansi kwezimo esheshayo lapho noma iyiphi ingxenye kuzuba inethiwekhi voltage avela ngaphezu 250 W.

Banikezwe izici unenviable amanethiwekhi yasekhaya kagesi, kanye degree of ukuwohloka, lona wamuva kubaluleke ngokukhethekile.

Izinzuzo esemqoka eziphuthumayo wesifunda amadlambi

• Ijubane eliphezulu kakhulu yempendulo.
• Ukuvikelwa imishini ngokumelene amandla yokwanda kwama kanye nomsebenzi sindisa.
• Ikhono usebenze ezimweni kusuka -25 kuya +50 degrees Celsius.
• Huge embundwini ngokuqina.

Kuyini RCD?

Thina awanakuziziba "Umphikisi" yesibili kule mpikiswano eyayinesihloko esithi "eziphuthumayo wesifunda amadlambi noma RCD." Kuyini RCD?

Lokhu isifinyezo imele "RCD". Ukuqalisa Kwenziwa uma ubhalisa khona ukuvuza imisinga. Kalula nje, yingoba singakanani zamanje kudivayisi phezu wire olulodwa, okufanayo kumelwe okunye wiring indawo. Uma zamanje uqala ukushiya phansi noma phansi wire, Ukuvikelwa kwabangela kweso, ngokushesha nokunqamula kunethiwekhi ugesi.

uhlelo ezinjalo kuba isibopho (!) Kufanele ibekwe amaqembu uphuma khona, kanye boilers, imishini yokuwasha kanye izitofu kagesi. Amadivayisi anjalo musa ukuvikela (!) inqubo yakho futhi bakha imizila edingekayo yokwenza wesistimu sindisa noma nesifunda esincane.

Izimo yokugcina ngokuvamile kakhulu hhayi kunakwe entabeni zikagesi, ngubani ngenxa izikimu eshibhile ngokuvamile ukuyisebenzisa wedwa RCD. Ngaphezu kwalokho, kukhona inzalo kanye bungobobugovu, lapho sidlula ngoba umehluko okuzenzakalelayo, okuyinto mkhulu izindleko.

ulwazi oluyisisekelo mayelana RCD kudivayisi

Siyini leso simiso umsebenzi we RCD? Ukusebenza kwawo kusekelwe ukusabela inzwa zamanje ku ushintsho enanini umehluko babashayeli zamanje.

Uyini inzwa zamanje? Kuyinto transformer abavamile kodwa ushintshwe ngokuvumelana uhlobo core toroidal. IThrojani efaka isimeli seseva adalule usebenzisa edluliselwe magnetoelectric kokuba ezwela eziphakeme ngokwedlulele.

Kubalulekile wazi ukuthi bonke RCD okwenziwe kule wesifunda zakudala, zinokwethenjelwa kakhulu namadivayisi elula abe enokwethenjelwa kakhulu futhi ukwethembeka.

Kumele wazise ukuthi namuhla kukhona RCDs electronic, okuncike wesifunda ekhethekile electronic. Isifunda edluliselwe noma isenzo ngalo mshini ukuthi kuvula wesifunda futhi esimweni isidingo esinjalo. Lapha esifaka RCD kudivayisi.

Kusukela lokho izingxenye siqukethe actuator?

• Ngenxa ngqo ukuxhumana kwesigcawu isethelwe esiphezulu Inani lamanje.
• I iziphethu, okuyinto ngokushesha ephula wesifunda uma umsebenti wayo ubelokhu nezinkinga ezithile.

Uma ufuna ukuhlola ngokwakho ukusebenza idivayisi, kuyoba okwanele ukuba chofoza inkinobho "Test". Kulokhu, secondary izinkampani eyayenziwe nginomdlandla futhi edluliselwe (kumele, noma kunjalo). Ngakho uma udinga kalula futhi ngaphandle noma yini kwaba izindleko Ungahlola ukuseviswa kuzo zonke imishini yayo.

Isimiso ezisebenza we RCD

Ekhuluma operation evamile, wamanje (I1 = I2) igelezela kuzo isiqondiso esiphikisayo okufanayo, ngokuyenga imisinga magnetic secondary emazombezombe we transformer (F1 = F2). Sinenkosi ncamashi kwenani elifanayo, kanjalo ukukhansela nomunye. Kusukela samanje yesibili emazombezombe kulokhu empeleni zero, ukusebenza edluliselwe singenzeka yini.

Sebenza RCD ukuvuza

Ngo ukuxhumana izingxenye conductive, lamanje ukuvuza kwenzeka. Kulesi simo I1 yamanje akusho I2 alinganayo, futhi ngenxa yalokho yesibili zamanje emazombezombe livela ogama value yanele ukuba usebenze edluliselwe zokuzivikela. It kuphakamisa inkinobho entwasahlobo sivaliwe RCD.

Umehluko phakathi izinhlelo ezimbili Ukuvikelwa

Ukuze indaba yethu ukuqhubeka phambili, sizokuqinisa futhi uthole ukuthi yini umehluko kusuka RCD eziphuthumayo wesifunda oluseduze. Asinakusho ukuthi umehluko ngakho ezinqala kakhulu, kodwa zisekhona.

Kufanele kuqashelwe ukuthi umbiko we lolu daba kubaluleke kakhulu, njengoba zihlukaniswa komunye nomunye, amadivayisi ngezinye izikhathi abakwazi ngisho ezinye Electricians. Nokho, akukho lutho isimanga: ayefana kakhulu, ngisho izithombe.

Umehluko omkhulu kusukela RCD eziphuthumayo wesifunda amadlambi wukuthi ziklanyelwe ngezinhloso eziningi ezahlukahlukene. Sishilo kakade lokhu ngenhla, kodwa phinde it waphinda: i RCD ingasetshenziswa yini ukuvikela imishini kanye wiring kusukela sindisa noma nesifunda esincane! Ngaphezu kwalokho, phambi RCD qiniseka ukhweze full wesifunda, okuzokwenza ugcine kudivayisi uqobo kusuka lolu hlobo enkingeni. Yilokho lihlukile RCD eziphuthumayo wesifunda oluseduze.

Qiniseka ukuthi ucabangele lokhu lapho uthenga noma ngokuxhumana ikakhulukazi ugesi "Cabangisisa", abantu abajabulayo ukusindisa on amasu akho.

Eziphuthumayo wesifunda amadlambi kulesi sici kungcono kakhulu ngoba ihlanganisa e izindlu efanayo njengoba RCD nowesifunda full. Ngakho, lolu hlobo idivayisi akusho kuphela ukuvikela abantu umuntu abanjwe ugesi, kodwa futhi ugcine wiring yakho futhi imishini nokutubeka uma short circuit. Ngakho, RCD nowesifunda eziphuthumayo amadlambi, okuyinto umehluko phakathi kwethu isanda kudalulwe kukhona izindlela eziningana ezihlukahlukene.

Nalapha futhi, ezingase umshini umehluko ingasetshenziswa njengendlela fuse lihambele imizi okushiywe kuyo kunobungozi njalo ukuminyana ezingamahlalakhona kunethiwekhi.

Lokhu - ngokungafani efakwe RCD eziphuthumayo wesifunda oluseduze. Kodwa indlela yokwenza izinqumo ezifanele esitolo? Phela, siye kakade wakhuluma iqiniso lokuthi lezi amadivaysi zifana kakhulu bodwa ngisho izithombe.

Thenga kwesokudla!

Okokuqala, sinake igama idivayisi ngqo. Namuhla, cishe bonke abakhiqizi ekugcineni wahamba ukuhlangabeza amakhasimende, deigning ucacise imininingwane mayelana amadlambi eziphuthumayo wesifunda noma RCD phambi kwakho phezu kwezindlu kudivayisi. Yingakho sasingeke ukuncoma ukuthenga imishini enjalo e China. Namaqhinga Asians noma lutho nhlobo ukhombise noma alenze, uyisebenzisa kuphela izimpawu kuyaqondakala kalula.

Cishe ngaso esigabeni esifanayo zihlanganisa neseluleko mayelana ufunda lokubeka uphawu, lapho kumelwe ngaso sonke isikhathi kuboniswe wonke kudivayisi izindlu efanayo noma kwikhava yawo (ngaphansi khetho okunokwethenjelwa).

Ngakho, uma ubona esimweni kuphela okuzisholo Inani lamanje (16, isibonelo), kanye nezinye izincwadi phambi lolu phawu alikho, lezi enikhuluma e ezandleni RCD. Phawula ukuthi "16" kulokhu kusho "Amps." Uma phambi amadijithi kukhona izinhlamvu B, C, noma i-D-ke ezandleni kuwe wesifunda amadlambi eziphuthumayo. Lezo zincwadi zibonisa izici ejwayelekile nokukhishwa ezishisayo kanye kagesi, kodwa ezingeni lasemakhaya ukukhokhela ukunakekelwa okukhethekile kubo akudingekile.

Futhi, lokho akusho ubuhlungu ukubheka futhi ngesikhathi umdwebo wiring. Le ndlela luyindida kancane xaxa, kodwa inikeza 100% isiqinisekiso yokuzihlukanisa kwamangqamuzana ngokwemisebenzi yawo. Lolu lwazi kufanele futhi ukuboniswa iphakethe. Ngokwesibonelo, uma umbonisi wesifunda ubonisa khona eziphuthumayo wesifunda amadlambi esibhalwe ukuthi "Test" ke phambi kwenu kuphela iyona RCD (akumelwe kudidaniswe!). Ngakho, uma kukhona "test," futhi ubonisa ezithothene ikhoyili, wena ubambe ezandleni zakho umshini umehluko.

Ekugcineni, kukhona abanye umqondo ukuze sinake Ubukhulu jikelele. Uma sikhuluma amadala onobuhle eziphuthumayo wesifunda amadlambi, zingabantu umyalelo ezidlula kunenani RCD. Ngalezo zinsuku nje abakwazanga ukukhiqiza ukukhishwa ngokwanele icwecwe, ngakhoke kudingeka umthamo omkhulu kwangaphakathi izindlu. Isexwayiso! Zonke imishini umehluko yesimanje okwamanje luthathe indawo encane!

Nokho, kubalulekile ngikuxwayise ukuthi indima yokugcina obraschatsya iyiphi nzulu akufanele ke, ngoba manje kukhona omningi amadivayisi ngokuphelele alinganayo.

Yiya phezulu

Ngakho, amadlambi eziphuthumayo wesifunda noma RCD? Yini sikhonjiswe kuzo zonke kulokhu okungenhla? Kungcono ukukhetha ukuthi yini kunokwethenjelwa futhi ezifanele ukusetshenziswa ku ezingokoqobo zasekhaya? Ukuze siphendule lo mbuzo, siqhathanisa amadivayisi kusukela izinkomba eziyisithupha. Ukuqhathanisa ngokucophelela ngobuhle nangobubi bawo, sizozama ngokwengeziwe ukuze kufinyelelwe esivumelwaneni.

Umqulu elalihlala kudivayisi kudeshibhodi

Yiqiniso, kulesi sici yimuphi umehluko obalulekile kungabonwa sitholwa kuphela yilabo isikhala okuncane kakhulu nendlu akuvumeli uphawu ephasishi evamile isihlangu kagesi.
