Ii-RCD zodidi lwe-B zibonelela ngokhuseleko olungcono kunye nokhuseleko kwiinkqubo zombane zanamhlanje apho i-DC kunye namaza angaqhelekanga aqhelekileyo. Ziyilelwe ukunqumla umbane ngokuzenzekelayo xa zibona ukungalingani okanye impazamo, zithintela iimeko ezinokuba yingozi. Njengoko imfuno yeenkqubo zamandla avuselelekayo kunye nezithuthi zombane ziqhubeka zikhula, ii-RCD zodidi lwe-B ziye zayimfuneko ekuqinisekiseni ukhuseleko lobu buchwepheshe butsha. Banceda ekuthinteleni ukothuka kombane, imililo, kunye nomonakalo kwisixhobo esibuthathaka ngokufumanisa ngokukhawuleza kwaye bayeke naziphi na iimpazamo kwinkqubo yombane. Ngokubanzi, Uhlobo lwe-RCDs luyinkqubela phambili ebalulekileyo kukhuseleko lombane, lunceda ukugcina abantu kunye nepropati bekhuselekile kwihlabathi ngokunyuka kokusetyenziswa kwamandla e-DC kunye namaza ombane angeyomfuneko.2

Iimpawu ze JCRB2-100 Uhlobo B RCDs

 

Ii-RCD ze-JCRB2-100 Uhlobo lwe-B zizixhobo ezikhuselekileyo zombane ezilungiselelwe ukubonelela ngokhuseleko olubanzi kwiindidi ezahlukeneyo zeempazamo kwiinkqubo zombane zanamhlanje. Iimpawu zabo eziphambili ziquka:

 

Ubuthathaka bokuhamba: 30mA

 

Ukukhubeka kobuntununtunu be-30mA kwi-JCRB2-100 Type B RCDs kuthetha ukuba isixhobo siya kuzivala ngokuzenzekelayo unikezelo lwamandla ukuba sibhaqa ukuvuza kombane okukhoyo kwi-30 milliamps (mA) okanye ngaphezulu. Lo mgangatho wobuntununtunu ubalulekile ekuqinisekiseni iqondo eliphezulu lokhuseleko kwizinto ezinokubakho zothuso lombane okanye imililo ebangelwa ziziphene zomhlaba okanye imisinga evuzayo. Ukuvuza kwangoku okuyi-30mA okanye ngaphezulu kunokuba yingozi kakhulu, kunokubangela ukwenzakala okumandundu okanye nokufa ukuba kuyekwa kungajongwa. Ngokukhubeka kweli nqanaba liphantsi lokuvuza, i-JCRB2-100 inceda ukuthintela iimeko eziyingozi ukuba zingenzeki, ukunqumla umbane ngokukhawuleza ngaphambi kokuba impazamo ibangele ingozi.

 

I-2-Pale / iSigaba esinye

 

Ii-RCD ze-JCRB2-100 Uhlobo lwe-B zenzelwe njengezixhobo ze-2-pole, oku kuthetha ukuba zenzelwe ukusetyenziswa kwiinkqubo zombane zesigaba esisodwa. Iinkqubo zesigaba esisodwa zixhaphake kumakhaya okuhlala, iiofisi ezincinci, kunye nezakhiwo zorhwebo ezilula. Kwezi setingi, amandla enqanaba elinye aqhele ukusetyenziswa ukunika amandla izibane, izixhobo zombane, kunye neminye imithwalo emincinci yombane. I-2-pole configuration ye-JCRB2-100 ivumela ukuba ibeke iliso kwaye ikhusele zombini abaqhubi abaphilayo kunye nabangathathi hlangothi kwisiphaluka sesigaba esisodwa, ukuqinisekisa ukukhuselwa okubanzi kwiimpazamo ezinokuthi zenzeke kuwo nawuphi na umgca. Oku kwenza ukuba isixhobo silungele kakuhle ukukhusela ukufakwa kwesigaba esinye, esixhaphakileyo kwiindawo ezininzi zemihla ngemihla.

 

Umlinganiselo wangoku: 63A

 

Ii-RCD ze-JCRB2-100 zohlobo lwe-B zinezinga langoku le-63 amps (A). Olu kulinganisa lubonisa ubuninzi bombane okhoyo isixhobo esinokusingatha ngokukhuselekileyo phantsi kweemeko eziqhelekileyo zokusebenza ngaphandle kokukhubeka okanye ukugcwala. Ngamanye amazwi, i-JCRB2-100 ingasetyenziselwa ukukhusela iisekethe zombane kunye nemithwalo ukuya kuma-63 amps. Olu kulinganisa lwangoku lwenza ukuba isixhobo silungele uluhlu olubanzi lwezicelo zorhwebo zokuhlala kunye nezilula, apho imithwalo yombane ngokuqhelekileyo iwela ngaphakathi kolu luhlu. Nangona kunjalo, kubalulekile ukuqaphela ukuba nokuba ingoku ingaphakathi komlinganiselo we-63A, i-JCRB2-100 iya kuhamba ukuba ibona ukuvuza kwangoku kwe-30mA okanye ngaphezulu, njengoko eli linqanaba layo lokukhubeka kukhuseleko lwempazamo.

 

Ubungakanani bombane: 230V AC

 

I-JCRB2-100 Uhlobo lwe-RCD lwe-RCD lunomlinganiselo wombane we-230V AC. Oku kuthetha ukuba ziyilelwe ukuba zisetyenziswe kwiinkqubo zombane ezisebenza ngamandla ombane angama-230 volts alternating current (AC). Lo mlinganiselo wombane uxhaphakile kwiindawo ezininzi zokuhlala kunye nezicelo ezilula zorhwebo, okwenza i-JCRB2-100 ilungele ukusetyenziswa kwezi ndawo. Kubalulekile ukuqaphela ukuba isixhobo akufuneki sisetyenziswe kwiinkqubo zombane ezineevoltheji eziphezulu kunomthamo wombane olinganisiweyo, njengoko oku kusenokwenzakalisa isixhobo okanye kubeke esichengeni amandla aso okusebenza kakuhle. Ngokubambelela kumlinganiselo wombane we-230V AC, abasebenzisi banokuqinisekisa ukuba i-JCRB2-100 iya kusebenza ngokukhuselekileyo nangempumelelo kuluhlu olucetywayo lombane.

 

Umthamo wangoku weSekethe emfutshane: 10kA

 

I-short-circuit current capacity ye-JCRB2-100 Type B RCDs yi-10 kiloamps (kA). Olu linganiso lubhekiselele kubuninzi bombane wesekethe emfutshane isixhobo esinokumelana naso phambi kokuba sigcine umonakalo okanye ukusilela. Imisinga yeesekethe ezimfutshane ingenzeka kwiinkqubo zombane ngenxa yeempazamo okanye iimeko ezingaqhelekanga, kwaye ingaba phezulu kakhulu kwaye ibenokonakalisa. Ngokuba nomthamo okhoyo we-10kA omfutshane, i-JCRB2-100 yenzelwe ukuba ihlale isebenza kwaye ibonelele ngokhuseleko nakwimeko yesiphambeko esibalulekileyo sesekethe, ukuya kuthi ga kwi-10,000 amps. Eli nqaku liqinisekisa ukuba ifowuni inokukhusela ngokufanelekileyo inkqubo yombane kunye namacandelo ayo xa kwenzeka iimpazamo eziphezulu zangoku.

 

IP20 yoKhuseleko lwenqanaba

 

Ii-RCD ze-JCRB2-100 Uhlobo lwe-B lunomlinganiselo wokukhusela we-IP20, omele "uKhuseleko lwe-Ingress" kwinqanaba le-20. Olu luhlu lubonisa ukuba isixhobo sikhuselekile kwizinto eziqinileyo ezinkulu kune-12.5 millimeters ngobukhulu, njengeminwe okanye izixhobo. Nangona kunjalo, ayinikezeli ukhuseleko emanzini okanye kolunye ulwelo. Ngenxa yoko, i-JCRB2-100 ayifanelekanga ukusetyenziswa kwangaphandle okanye ukufakwa kwiindawo apho inokuthi ibonakaliswe kumswakama okanye ulwelo ngaphandle kokhuseleko olongezelelweyo. Ukusebenzisa isixhobo kwindawo yangaphandle okanye emanzi, kufuneka ifakwe ngaphakathi kwendawo evaliweyo enika ukhuseleko oluyimfuneko kumanzi, uthuli kunye nezinye izinto zokusingqongileyo.

 

Ukuthotyelwa kwe-IEC/EN 62423 kunye ne-IEC/EN 61008-1 iMigangatho

 

I-JCRB2-100 Uhlobo lwe-RCDs lwe-B luyilwe kwaye lwenziwa ngokuhambelana nemigangatho emibini ebalulekileyo yamazwe ngamazwe: IEC / EN 62423 kunye ne-IEC / EN 61008-1. Le migangatho ichaza iimfuno kunye neenqobo zovavanyo lweResidual Current Devices (RCDs) ezisetyenziswa kufakelo lwe-low-voltage. Ukuthotyelwa kwale migangatho kuqinisekisa ukuba i-JCRB2-100 ihlangabezana nokhuseleko oluqinileyo, ukusebenza, kunye nezikhokelo zekhwalithi, iqinisekisa umgangatho ohambelanayo wokukhusela nokuthembeka. Ngokuthobela le migangatho yamkelwe ngokubanzi, abasebenzisi banokuthenjwa kubuchule besixhobo ukusebenza njengoko bekucetyiwe kwaye babonelele ngokhuseleko oluyimfuneko ngokuchasene neziphene zombane kunye neengozi.

 

Ukuqukumbela

 

IJCRB2-100 Uhlobo B RCDszizixhobo zokhuseleko eziphambili ezilungiselelwe ukunika ukhuseleko olubanzi kwiinkqubo zombane zanamhlanje. Ngeempawu ezinjengomda wokukhubeka we-30mA obuthathaka kakhulu, ukufaneleka kosetyenziso lwesigaba esinye, umlinganiselo wangoku we-63A, kunye nomlinganiselo wombane we-230V AC, zibonelela ngokhuseleko oluthembekileyo ngokuchasene neziphene zombane.
