Residual Tam Sim No Ntaus, JCRB2-100 Hom B

JCRB2-100 Hom B RCDs muab kev tiv thaiv tawm tsam cov kab mob tseem ceeb / lub ntiaj teb to hauv AC muab cov ntawv thov tshwj xeeb.

Hom B RCDs yog siv qhov twg du thiab / lossis pulsating DC seem uas tsis muaj, cov xaim tsis muaj zog yog los yog zaus ntau dua 50Hz; Piv txwv li, hluav taws xob tsheb them, qee cov khoom siv hluav taws xob, micro tiam lossis cov hluav taws xob me me (hluav taws xob me me) thiab cua tshuab hluav taws xob.

Taw qhia:

Hom B RCDs (Residual Tam sim no cov khoom siv tam sim no) yog hom khoom siv siv rau hluav taws xob kev nyab xeeb. Lawv tau tsim los muab kev tiv thaiv kev tiv thaiv ob thiab DC ua txhaum, ua rau lawv muaj cov khoom siv hluav taws xob ntau xws li hluav taws xob hluav taws xob, thiab kev siv hluav taws xob ntxiv. Hom B RCDs yog qhov tseem ceeb rau muab kev tiv thaiv txhij txhua hauv cov hluav taws xob niaj hnub.

Hom B RCDs muab ib qib kev nyab xeeb tshaj li RCDional tuaj yeem muab tau. Ntaus ib daim RCDs yog tsim los mus ncig ua si ntawm ib qho kev ua txhaum, thaum hom B RCDs tuaj yeem tseem pom DC seem tam sim no, ua rau lawv haum rau cov ntawv siv hluav taws xob. Qhov no yog qhov tseem ceeb npaum li cas rau cov chaw siv hluav taws xob thiab cov tsheb hluav taws xob txuas ntxiv loj hlob, tsim cov kev nyuaj tshiab thiab cov kev xav tau hluav taws xob kev nyab xeeb tshiab.

Ib qho ntawm cov 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 thauj khoom. Piv txwv li, hluav taws xob hluav taws xob cia siab rau kev tiv thaiv tam sim no, yog li tsim nyog ntawm cov kev tiv thaiv yuav tsum yog qhov kev nyab xeeb ntawm lub tsheb thiab them cov vaj tse. Ib yam li ntawd, txuas ntxiv dua tshiab lub tshuab (xws li cov panar hnub ci) feem ntau ua haujlwm ntawm DC lub zog, ua hom B RCDs ib qho tseem ceeb hauv cov teeb tsa no.

Hom B RCD yog dab tsi?

Hom B RCDs yuav tsum tsis txhob tsis meej pem nrog hom B mcbs lossis RCBOS uas tshwm sim hauv ntau lub vev xaib.

Hom B RCDs yog txawv tag nrho, txawm li cas los xij, hmoov tsis muaj ib tsab ntawv tau siv uas tuaj yeem siv tsis tau. Muaj hom B uas yog tus yam ntxwv thermal hauv MCB / RCBO thiab hom B txhais cov yam ntxwv hauv RCCB / RCD. Qhov no txhais tau tias yog li koj yuav pom cov khoom xws li RCBos nrog ob tus yam ntxwv, uas yog lub zog sib nqus (qhov no tuaj yeem yog cov hlau nplaum thiab hom B lossis C Thermal RCBO).

Hom B RCDs ua haujlwm li cas?

Hom B RCDs feem ntau yog tsim nrog ob lub chaw nyob tam sim no. Thawj zaug siv 'fluxgate' fluxate 'kom pab tau RCD los kuaj du DC tam sim no. Qhov thib ob siv cov thev naus laus zis zoo ib yam li ntaus AC thiab ntaus ib qho RCDs, uas yog qhov hluav taws xob ywj pheej.
