JCR4-125 yog cov khoom siv hluav taws xob muaj kev nyab xeeb tsim los hloov tam sim ntawm cov khoom siv hluav taws xob thaum hluav taws xob xau rau lub ntiaj teb raug kuaj pom ntawm theem teeb meem.Lawv muab kev tiv thaiv tus kheej siab los ntawm hluav taws xob poob siab.
Taw qhia:
JCR4-125 4 ncej RCDs tuaj yeem siv los muab kev tiv thaiv kev ua txhaum hauv ntiaj teb ntawm 3 theem, 3 lub tshuab xaim, vim tias qhov kev sib npaug tam sim no tsis tas yuav muaj qhov nruab nrab txuas nrog txhawm rau ua haujlwm zoo.
JCR4-125 RCDs yuav tsum tsis txhob siv los ua ib txoj hauv kev ntawm kev tiv thaiv kev tiv thaiv ncaj qha, tab sis tseem muaj txiaj ntsig hauv kev muab kev tiv thaiv ntxiv hauv qhov chaw muaj kev pheej hmoo siab uas yuav tshwm sim.
Txawm li cas los xij JIUCE JCRD4-125 4 ncej RCDs ua, qhov zoo tshaj plaws, xav tau ib tus neeg nruab nrab nruab nrab yuav tsum tau muab rau ntawm cov khoom siv ntawm RCD txhawm rau kom ntseeg tau tias qhov ntsuas hluav taws xob ua haujlwm txaus siab.Yog qhov kev sib txuas ntawm cov khoom nruab nrab tsis tuaj yeem ua tau, tom qab ntawd lwm txoj hauv kev los xyuas kom meej tias lub pob ntsuas kev ua haujlwm yog kom haum rau qhov ntsuas qhov ntsuas ntawm qhov nruab nrab ntawm tus ncej nruab nrab thiab theem ncej tsis cuam tshuam nrog kev sim khawm ua haujlwm.
JCRD4-125 4 ncej RCD muaj nyob rau hauv hom ac thiab A hom.AC hom RCDs tsuas yog rhiab rau sinusoidal yam txhaum tam sim no.Ib hom RCDs, ntawm qhov tod tes, muaj kev nkag siab rau ob qho tib si sinusoidal tam sim no thiab "unidirectional pulsed" tam sim no, uas tej zaum yuav muaj, piv txwv li, hauv cov tshuab nrog cov khoom siv hluav taws xob los kho qhov tam sim no.Cov khoom siv no muaj peev xwm tsim cov khoom siv hluav taws xob tsis zoo nrog cov khoom txuas txuas ntxiv uas AC hom RCD tsis tuaj yeem lees paub.
JCR4-125 RCD muab kev tiv thaiv lub ntiaj teb faults tshwm sim nyob rau hauv cov khoom siv thiab txo qhov cuam tshuam ntawm hluav taws xob poob rau tib neeg thiab yog li cawm tau txoj sia.
JCR4-125 RCD ntsuas qhov ntws tam sim no hauv cov kab hluav taws xob nyob thiab nruab nrab thiab yog tias muaj qhov tsis sib xws, uas yog tam sim no ntws mus rau lub ntiaj teb saum RCD rhiab heev, RCD yuav tawm mus thiab txiav tawm cov khoom siv.
JCR4-125 RCDs suav nrog cov cuab yeej lim dej los muab kev tiv thaiv kev tiv thaiv ib ntus hauv cov khoom xa mus rau chav tsev, yog li txo qhov tshwm sim ntawm qhov tsis xav tau tripping.

Yuav ua li cas RCD tiv thaiv kev raug mob - Milliamps thiab milliseconds
Ib qho hluav taws xob tam sim no tsuas yog ob peb milliamps (mA) tau ntsib rau ib pliag xwb yog txaus los tua cov neeg uas haum, noj qab nyob zoo.RCDs yog li muaj ob yam tseem ceeb rau lawv txoj haujlwm - tus nqi tam sim no uas lawv tso cai rau Lub Ntiaj Teb Leakage ua ntej kev khiav haujlwm - qhov ntsuas mA - thiab qhov ceev uas lawv ua haujlwm - ms ntsuam xyuas.
> Tam sim no: Hauv UK tus qauv hauv tsev RCDs ua haujlwm ntawm 30mA.Hauv lwm lo lus lawv yuav tso cai rau qhov tsis txaus ntseeg tam sim no hauv qab no txhawm rau txhawm rau suav cov xwm txheej hauv ntiaj teb tiag tiag thiab zam 'kev tsis sib haum xeeb', tab sis yuav txiav lub zog sai li sai tau thaum lawv pom qhov xau tam sim no ntawm 30mA lossis siab dua.
> Ceev: UK txoj cai BS EN 61008 qhia tias RCDs yuav tsum mus rau hauv qee lub sijhawm nyob ntawm seb qhov tsis txaus ntseeg tam sim no.
1 x Luas = 300 ms
2 x Luas = 150 ms
5 x 40 ms
'Hauv' yog lub cim muab rau tripping tam sim no - piv txwv li, 2 x Hauv ntawm 30mA = 60mA.
RCDs siv nyob rau hauv kev lag luam thiab kev lag luam ib puag ncig muaj mA ntau dua ntawm 100mA, 300mA thiab 500mA
