JCRB2-100 Hom B RCDs

JCRB2-100 Hom B RCDs muab kev tiv thaiv tiv thaiv qhov cuam tshuam tsis zoo tam sim no / lub ntiaj teb to hauv AC cov ntawv thov nrog cov yam ntxwv tshwj xeeb waveform.

Hom B RCDs yog siv qhov chaw du thiab / lossis pulsating DC residual tam sim no tuaj yeem tshwm sim, tsis yog sinusoidal waveforms tam sim no lossis zaus ntau dua li 50Hz;Piv txwv li, Hluav Taws Xob Hluav Taws Xob, qee yam khoom siv 1-theem, micro tiam lossis SSEGs (Small Scale Electricity Generators) xws li hnub ci vaj huam sib luag thiab cua tshuab hluav taws xob.

Product Detail

Taw qhia:

Hom B RCDs (Residual Current Devices) yog ib hom khoom siv rau kev nyab xeeb hluav taws xob.Lawv tau tsim los muab kev tiv thaiv ob qho tib si AC thiab DC qhov tsis raug, ua rau lawv tsim nyog rau ntau yam kev siv, suav nrog cov DC rhiab loads xws li hluav taws xob tsheb, hluav taws xob hluav taws xob, thiab kev lag luam machinery.Hom B RCDs yog qhov tseem ceeb rau kev muab kev tiv thaiv zoo hauv kev teeb tsa hluav taws xob niaj hnub.

Hom B RCDs muab ib qib kev nyab xeeb tshaj li cov qauv RCDs tuaj yeem muab tau.Hom A RCDs yog tsim los mus ncig hauv qhov xwm txheej ntawm AC txhaum, thaum Hom B RCDs tuaj yeem ntes DC seem tam sim no, ua rau lawv tsim nyog rau kev siv hluav taws xob loj hlob.Qhov no yog qhov tseem ceeb tshwj xeeb vim qhov kev thov rau cov tshuab hluav taws xob txuas ntxiv mus thiab cov tsheb hluav taws xob txuas ntxiv mus ntxiv, tsim cov kev sib tw tshiab thiab cov kev xav tau rau kev nyab xeeb hluav taws xob.

Ib qho txiaj ntsig tseem ceeb ntawm Hom B RCDs yog lawv lub peev xwm los muab kev tiv thaiv nyob rau hauv lub xub ntiag ntawm DC rhiab loads.Piv txwv li, cov tsheb hluav taws xob cia siab rau tam sim no ncaj qha rau kev txhawb nqa, yog li cov qib tsim nyog ntawm kev tiv thaiv yuav tsum muaj nyob rau hauv qhov chaw kom muaj kev nyab xeeb ntawm lub tsheb thiab kev them nyiaj.Ib yam li ntawd, cov tshuab hluav taws xob tauj dua tshiab (xws li hnub ci vaj huam sib luag) feem ntau ua haujlwm ntawm DC lub zog, ua rau Hom B RCDs yog ib qho tseem ceeb hauv cov kev teeb tsa no.

Hom B RCD yog dab tsi?

Hom B RCDs yuav tsum tsis txhob totaub nrog Hom B MCBs lossis RCBOs uas tshwm sim hauv ntau lub vev xaib tshawb nrhiav.

Hom B RCDs sib txawv kiag li, txawm li cas los xij, hmoov tsis zoo tib daim ntawv tau siv uas tuaj yeem ua rau tsis meej pem.Muaj Hom B uas yog tus yam ntxwv thermal hauv MCB / RCBO thiab Hom B txhais cov yam ntxwv sib nqus hauv RCCB / RCD.Qhov no txhais tau hais tias yog li koj yuav pom cov khoom xws li RCBOs nrog ob tus yam ntxwv, uas yog cov khoom sib nqus ntawm RCBO thiab cov khoom siv thermal (qhov no yuav yog Hom AC lossis A sib nqus thiab hom B lossis C thermal RCBO).

Hom B RCDs ua haujlwm li cas?

Hom B RCDs feem ntau yog tsim los nrog ob lub tshuab tshawb pom tam sim no.Thawj zaug siv 'fluxgate' thev naus laus zis los pab RCD kom pom cov DC tam sim no.Qhov thib ob siv cov thev naus laus zis zoo ib yam li Hom AC thiab Hom A RCDs, uas yog voltage ywj siab.
