JCR2-125 RCD yog lub rhiab tam sim no uas tsim los tiv thaiv tus neeg siv thiab lawv cov khoom los ntawm hluav taws xob thiab hluav taws xob hluav taws xob los ntawm kev tawg tam sim no raws li tau dhau los ntawm koj lub tsev neeg siv khoom / lub thawv xa khoom thaum pom qhov tsis txaus lossis cuam tshuam rau txoj hauv kev tam sim no.
Taw qhia:
Ib qho khoom siv hluav taws xob tam sim no (RCD), qhov seem hluav taws xob tam sim no (RCCB) yog ib qho khoom siv hluav taws xob tiv thaiv hluav taws xob uas cuam tshuam cov hluav taws xob tam sim no nrog cov dej xau mus rau hauv av.Nws yog los tiv thaiv cov khoom siv thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj loj los ntawm hluav taws xob tsis tu ncua.Kev raug mob tseem tuaj yeem tshwm sim nyob rau qee kis, piv txwv li yog tias tib neeg tau txais kev poob siab luv ua ntej qhov hluav taws xob hluav taws xob raug rho tawm, ntog tom qab tau txais kev poob siab, lossis yog tias tus neeg kov ob lub conductors tib lub sijhawm.
JCR2-125 yog tsim los txiav tawm lub voj voog yog tias muaj qhov xau tam sim no.
JCR2-125 Residual tam sim no cov cuab yeej (RCDs) tiv thaiv koj los ntawm kev txais hluav taws xob poob qis.Kev tiv thaiv RCD yog kev cawm neeg txoj sia thiab tiv thaiv hluav taws.Yog tias koj kov cov hlau liab qab lossis lwm yam khoom siv nyob hauv cov neeg siv khoom, nws yuav ua rau cov neeg siv kawg tsis raug mob.Yog hais tias tus installer txiav los ntawm ib tug cable, cov khoom seem uas nyob rau tam sim no yuav hloov tawm lub zog ntws mus rau lub ntiaj teb.RCD yuav raug siv los ua cov khoom xa tuaj uas pub cov khoom siv hluav taws xob rau cov khoom siv hluav taws xob.Nyob rau hauv qhov xwm txheej ntawm qhov hluav taws xob sib npaug, RCD tawm mus thiab disconnects cov khoom siv rau cov khoom siv hluav taws xob.
Ib qho khoom siv tam sim no los yog paub zoo dua li RCD yog cov cuab yeej kev nyab xeeb tseem ceeb hauv ntiaj teb hluav taws xob.Ib qho RCD feem ntau yog siv los tiv thaiv tib neeg los ntawm kev puas tsuaj hluav taws xob.Yog tias muaj teeb meem nrog cov khoom siv hauv tsev, RCD tshwm sim vim yog lub zog hluav taws xob thiab cuam tshuam cov hluav taws xob tam sim no.RCD yog tsim los kom teb tau sai.Cov cuab yeej tam sim no uas muaj nyob hauv saib xyuas cov hluav taws xob tam sim no thiab qhov kev ua haujlwm tsis zoo uas lub cuab yeej ua sai sai.
RCD's muaj nyob rau hauv ntau hom sib txawv thiab hnov mob txawv nyob ntawm seb muaj cov khoom siv DC lossis ntau zaus.Cov qib kev nyab xeeb uas lawv muab rau cov dej nyob tam sim no ntau dua li cov fuse zoo tib yam lossis cov hluav taws xob hluav taws xob.Cov nram qab no RCD muaj nyob nrog cov cim sib txawv thiab tus tsim lossis tus neeg tsim khoom yuav tsum xaiv cov cuab yeej tsim nyog rau daim ntawv thov tshwj xeeb.
Hom S (Lub Sijhawm ncua)
Hom S RCD yog cov khoom siv sinusoidal residual tam sim no suav nrog lub sijhawm ncua sijhawm.Nws tuaj yeem ntsia tau ntws los ntawm Hom AC RCD los muab kev xaiv.Lub sij hawm ncua RCD tsis tuaj yeem siv rau kev tiv thaiv ntxiv vim nws yuav tsis ua haujlwm nyob rau lub sijhawm xav tau ntawm 40 mS
Hom AC
Hom AC RCDs (General Hom), uas feem ntau ntsia hauv tsev, yog tsim los siv rau kev hloov pauv sinusoidal residual tam sim no los tiv thaiv cov khoom siv uas yog resistive, capacitive lossis inductive thiab tsis muaj cov khoom siv hluav taws xob.
Hom RCDs tsis muaj sijhawm ncua sijhawm thiab ua haujlwm tam sim ntawm kev tshawb pom qhov tsis txaus.
Hom A
Hom A RCDs yog siv rau alternating sinusoidal residual tam sim no thiab rau residual pulsating ncaj qha tam sim no mus txog 6 mA ..
