Yuav ua li cas yog ib tug residual tam sim no ntaus ntawv

Hluav taws xob cov pab kiag li lawm yog tag nrho cov nyob ib ncig ntawm peb. Tej zaum, txawm tom qab tawm hauv rau ib tug lub tsheb kauj vab sab nraum lub nroog, peb tsis txhob hnov qab mus muab nyob rau hauv ib tug xov tooj ntawm tes hnab tshos, thiab nws yog ib qho hluav taws xob ntaus ntawv. Nyob rau hauv cov ntaub ntawv no, txhua tus neeg los ntawm thaum yau paub txog cov kev txaus ntshai fraught nrog hluav taws xob khoom siv. Txawm li cas los, muab li cov kev pab cuam uas coj qhov hluav taws xob lub zog, ib tug tej zaum yuav tsum tsis txhob. Tshwj xeeb tshaj yog tam sim no, thaum uas yuav tsum tau ntawm cov SAE yog tau txais tougher, thiab kev ua lag luam qhia tshiab kev tiv thaiv. Ntawm lawv, tshwj xeeb mloog yuav tsum tau muab kev tiv thaiv pab kiag li lawm.

Grounding, tsis siv neeg, RCD ... yog dab tsi tom ntej no?

Yog hais tias ib tug ob peb xyoo dhau los, cov pa electrician hais kom sau cov kev daws teeb meem tsim los tiv thaiv cov neeg los ntawm hluav taws xob poob siab, ces muaj tseeb nws yuav muab ib tug tiv grounding, fuse thiab kom tsuas Circuit Court breaker. Ib daim ntawv yuav tsum tau supplemented los ntawm lub hwj chim transformer rho tawm thiab cov kev tswj saw. Tab sis yog hais tias tus zus tau tej cov no cov ntsiab tsuas yog tej yam ntuj tso, ces yuav ua li cas nrog nws tsev neeg hluav taws xob circuits nyob rau hauv uas lub grounding Circuit Court yog tsis muab rau? Tshuab? Tab sis txawm lub feem ntau rhiab qauv (cov chav kawm ntawv A) yog txhais thaum lub nyob tam sim no yog ua zoo tshaj los ntawm yuav luag tsib lub sij hawm! Nrog lub advent ntawm haib tsev cov khoom siv lo lus nug pib demand ib tug tam sim ntawd tov. Thiab nws tau pom. Lawv muab tau ib residual tam sim no ntaus ntawv, los yog RCD. Txawm tias txhua yam tsim nyog rau nws cov tshwm sim tau ntev tau paub tias yuav sib sau ua ke ua ke tswv yim thiab muab tso rau lawv mus rau hauv hlau thiab yas yuav nyuam qhuav xwb. Yog li, lub dawm taw ntaus ntawv yuav tsum tau hu ua ib tug novelty tsuas nrog reservations.

teebmeem kev cai

Raws li yog lub npe hu los ntawm physics tsev kawm ntawv cov hoob kawm, tus tam sim no dhau los ntawm tus neeg xyuas pib generates ib ncig ntawm nws tus kheej ib tug sib nqus teb. Ntxiv mus, nws kab siv tig. Orientation txog vectors txiav txim los ntawm cov lus tsa suab ntawm them elementary hais. Neeg twg uas xav kawm kom paub ntau ntxiv txog nws, koj yuav tsum nyeem txog kev siv ntawm txoj cai-tes txoj cai (txoj cai muaj hau ntswj). Yuav kom to taub yuav ua li cas khiav lag luam yog cov RCD dawm taw ntaus ntawv, nws yog txaus kom to taub tias lub teb rotates nyob ib ncig ntawm neeg xyuas pib nrog tam sim no.

Cov tom ntej no cov khoom uas yog ib nqi nco ntsoov, - ib tug tam sim no tshwm sim los ntawm ib tug kaw neeg xyuas pib uas hla ntawm txoj kab ntawm cov rotating magnetic teb.

Nws yog nyob rau cov ob kev cai raws li residual tam sim no ntaus ntawv.

Tsim thiab txoj ntsiab cai ntawm cov lag luam

Hauv lub vaj tse RCD yog ib co toroidal tam sim no transformer los ntawm kev uas lub conductors yog omitted. Sab nraum lawv muaj tso tawm rau lub davhlau ya nyob twg site.

Sawv cev rau ib tib theem network nrog ob tug conductors - thiab pes tsawg theem. Cov kis muaj ib tug residual tam sim no ntaus ntawv. Thaum rau ntawm qhov chaw RCD Circuit Court tom qab qhov hluav taws xob load yog hloov, ntawm ua tam sim no pib ntws, tus nqi ntawm uas yog txiav txim los ntawm lub load peev xwm. Thaum tsis muaj to (av txhaum yog tsis tuaj kawm ntawv), cov ntxhee nyob rau hauv cov theem neeg xyuas pib thiab lub xoom yog tib yam (qhov txawv yog heev me me). Li ntawd, cov generated magnetic teb tig oppositely thiab offsetting, li ntawd, lawv geometric sum yog pes tsawg. Sai li sai tau raws li muaj ib tug los, muaj dab tsi sib txawv, thiab tsim ib daim teb. Vim hais tias nws tshwm sim nyob rau hauv lub transformer tam sim no RCD induction. Lub Xeem, Lub nrog nws tus kheej sib nqus teb attracts lub latch, uas tshem tawm lub xauv rov qab mechanism. Lub Circuit Court yog lawm. Xws li ib tug tov yog hu ua ib tug txawv Circuit Court breaker.
