IsiKhokelo esiSebenzayo kwi-Residual Current Circuit Breakers enoKhuseleko lwangoku

Yintoni i-RCBO?

AnI-I-RCBO- i-residual current circuit breaker with over current protection - is a low-voltage device protective device edibanisa ukukhuselwa komthwalo ogqithisiweyo, ukhuseleko olufutshane lwesiphaluka kunye nokufumanisa okukhoyo (ukuvuza) kwiyunithi enye ebunjiweyo. Ngaphakathi kwizindlu ezixineneyo, umatshini wokuhamba nge-thermal-magnetic uphatha ukulayisha ngaphezulu kunye neesekethe ezimfutshane, ngelixa i-zero-sequence current transformer ngokuqhubekayo ithelekisa ukuqukuqela kwangoku kwi-conductor ephilayo kunye nengathathi hlangothi. Xa umahluko udlula ireyithi yentsalela yangoku (IΔn), isixhobo sihamba ngaphakathi kwe-milliseconds, sinqumle unikezelo phambi kokuba ukuvuza kwangoku kungonakalisa abantu okanye kubangele umlilo.

Unokukhetha nini i-RCBO: iisekethe ezisezantsi ezifuna zombini ngaphezulu kokhuseleko lwangoku kunye nokhuseleko lokuvuza komntu - izixhobo zangaphandle, iisekethe zesixhobo, iigaraji, amagumbi angaphantsi, amagumbi okuhlambela kunye nezinye iindawo ezifumileyo okanye ezifikeleleka lula.

I-DABL-63 yeyodidi lwe-RCBO: isixhobo esinye, ukhuseleko oluthathu - eyona ndawo- kunye neendleko ezifanelekileyo zokhetho kwiisekethe zokugqibela zekhaya.

Ungayikhetha njani iRCBO elungileyo?

1. Ireyithingi yangoku (In): tshatisa umthwalo oqhubekayo wesekethe, kunye ne-headroom ye-inrush currents yezixhobo zombane (umzekelo, i-40A igubungela iisekethe eziqhelekileyo zezixhobo zendlu).

2. Umthamo wokuqhawula (Icn): kufuneka ube phezulu kunexesha elizayo le-short-circuit current kwindawo yofakelo; I-6kA ibandakanya amanqanaba aqhelekileyo eendawo zokuhlala kunye nezilula zorhwebo.

3. Iipali: I-1P + N yeesekethe zokugqibela zesigaba esisodwa kunye ne-compact DIN-rail mounting.

4. Uphawu lokuhamba: I-C-curve (5–10× In) kwimithwalo yendlu ngokubanzi kunye nesixhobo; I-B-curve ye-electronics enovakalelo; D-igophe lokuqalisa injini.

5. Imigangatho kunye nesiqinisekiso: Ukuthotyelwa kwe-IEC/EN 61009-1 kunye nokumakishwa kwe-CE sisiseko seeprojekthi zamazwe ngamazwe.

6. Isicelo: izixhobo zangaphandle, iisekethe zesixhobo kunye negaraji/izibane zangaphantsi zinokufuna ubuntununtunu obuphezulu kuneesekethe eziqhelekileyo zangaphakathi.

Ijongeka njani i-RCBO echazwe kakuhle

Ukwenza le khonkrithi, qwalasela i-DABL-63 ukusukaC · DADA Electric, i-1P+N intsalela yesaphuli sesekethe yangoku enokhuseleko lwangoku olubonisa ukuba ujonge ntoni kolu didi lwesixhobo:1P+N uqwalaselo

● Ipali ephilayo itshintshiwe kwaye ingathathi hlangothi ilandelwe, i-compact ye-DIN-ibhodi yokuhanjiswa kwe-rail ye-40A elinganiselwe ngoku (In)

● Nge-C-curve tripping (C40) 230V ~ i-voltage elinganisiweyo

● 6kA ukophuka umthamo (Icn)

● IΔn = 0.01A (10mA) i-high-sensitivity residual ukhuseleko lwangoku

● Ukuthotyelwa kwe-IEC/EN 61009-1

● Iqhosha le-T elibomvu lovavanyo lokutshekishwa kwamaxesha athile, iitheminali eziphawulwe 1/2/N, ileyibhile yokureyitha kunye nedayagramu yesekethe eprintwe kwindlu.

● Yakhelwe izixhobo zangaphandle, izixhobo zasekhaya, igaraji kunye nezibane zangaphantsi

Ingqiqo emva kwesi nkcazo

I-40A, i-1P + N isakhelo esine-10mA ukhuseleko oluphezulu lokuvuza olunovakalelo lugubungela uninzi lweesekethe zokuhlala zokugqibela: I-40A ihambelana nomthwalo wesixhobo esiqhelekileyo kunye neesekethe zesokhethi, i-1P + N igcina isixhobo sihlangene kwiibhodi zokusasaza ezixineneyo, kwaye uvakalelo lwe-10mA lunikeza umaleko owongezelelweyo wokhuseleko lomntu kanye apho i-IEC ifuna khona isikhokelo kunye nabantwana ngaphandle.

FAQ

Umbuzo: Yintoni i-RCBO?

A: I-RCBO - i-residual current circuit breaker with over current protection - is a reset table low-voltage device protective edibanisa ukukhuselwa komthwalo ogqithisiweyo, ukhuseleko olufutshane lwesiphaluka kunye nokhuseleko lwangoku (ukuvuza) kwiyunithi enye, ngokuqhelekileyo ukuya kwi-63A kwiisekethe zokugqibela.

Q: Yintoni umahluko phakathi kwe-RCBO kunye ne-MCB?

A: I-MCB ibonelela kuphela ngokugqithiswa kunye nokhuseleko lwesekethe emfutshane. I-RCBO yongeza i-residual current (ukuvuza) ukufunyanwa phezulu, ukukhupha isiphaluka xa ukuvuza kwangoku kudlula i-IΔn - ukukhusela abantu kunye nokuthintela imililo yombane.

Q: Ithetha ntoni IΔn = 10mA?

A: IΔn yintsalela esebenzayo yangoku. I-10mA luphawu olunovakalelo oluphezulu: isixhobo siyahamba xa ukuvuza kwangoku kufikelela kwi-10mA, kukubonelela ngokhuseleko lomntu olukhawulezayo kunomlinganiselo wenjongo jikelele ye-30mA.

Q: Yintoni na i-DABL-63 RCBO?

A: I-DABL-63 yi-1P + N i-residual current circuit breaker kunye nokhuseleko lwangoku kwi-C·DADA Electric - 40A, i-C-curve, i-230V ~, i-6kA yokuqhawula amandla kunye ne-10mA ukukhuselwa kokuvuza okuphakamileyo, okuhambelana ne-IEC / EN 61009-1, kwi-garage appliances yangaphandle kunye nezixhobo zangaphandle.
