Txoj kev phom sij los ntawm hluav taws xob tau paub rau txhua tus. Ntawm no koj tuaj yeem ntxiv cov cua sov ntawm tus neeg xyuas pib, uas tshwm sim thaum muaj kev sib cuag xoob lossis luv luv. Tab sis tsis muaj hluav taws xob, ib tug neeg tsis xav txog nws lub neej ntev, uas txhais tau hais tias yuav tsum muaj txoj hauv kev los tswj lub zog no. Rau lub hom phiaj no, ntau yam khoom siv tiv thaiv tau tsim, suav nrog cov tshuab tsis siv neeg, hom uas peb yuav xav txog hnub no.

yam ntxwv dav dav ntawm Circuit Court breakers

Cov khoom siv tsis siv neeg yog cov khoom siv uas tuaj yeem qhib lub voj voog hauv lub sijhawm luv tshaj plaws thaum muaj cua sov, luv luv lossis lwm yam xwm txheej ceev. Nrog rau qhov tsis zoo ntawm cov cuab yeej, tsis muaj qhov tsis ntseeg tias nws yuav hnov mob ntau dhau ntawm cov qauv thiab tshem tawm qhov hluav taws xob los ntawm txoj kab, yog li tiv thaiv tsis yog tus neeg nws tus kheej xwb, tab sis kuj yog nws cov cuab yeej.

Circuit Breakers yuav txawv ntawm qhov siab tshaj plaws tam sim no,tus naj npawb ntawm cov ncej lossis cov qauv kev ua haujlwm. Txhua tus neeg uas tau tuaj hla cov khoom siv no paub tias nws lub cev yuav tsum tau cim - B, C lossis D. Thawj hom tuaj yeem raug ntaus nqi rau cov khoom siv hluav taws xob tsawg, thaum tom kawg yog siv ntau zaus hauv kev lag luam uas cov khoom thauj tam sim no tseem ceeb. Rau kev siv hauv tsev, xaiv hom cim C. Tus lej tom qab tsab ntawv yog qhov taw qhia ntawm qhov siab tshaj plaws tam sim no load, saum toj no uas lub cuab yeej yuav mus. Piv txwv li, VA cim C16 yuav tiv taus 16 A yam tsis muaj teeb meem, tab sis yog tias qhov ntsuas tau dhau lawm, nws yuav qhib lub voj voog thiab txo qhov voltage.

Hais txog hom kev sib tsoo hluav taws xob, muaj peb yam tseem ceeb:

  1. BA.
  2. RCD.
  3. Difavtomat.

Cia sim tshuaj xyuas lawv kom ntxaws ntxiv kom nkag siab lub hom phiaj ntawm kev tiv thaiv.

Tsis siv neeg hloov: nta, hom phiaj

Ib lub cuab yeej muaj peev xwm qhib lub voj voog thaum muaj kev cuam tshuam luv luv lossis kev sib txuas hauv network (overload ntawm cov khoom txuas nrog). Qhov no yog hom tseem ceeb ntawm automata, uas muaj 2 kev sib cuag (theem input / output) thiab ua haujlwm ntawm lub hauv paus ntsiab lus ntawm electromagnet, muaj xws li ib tug solenoid thiab ib tug pas nrig, raws li zoo raws li ib tug bimetal phaj. Nws hloov tawm hais tias nyob rau hauv ib txwm tam sim no load, qhov kev tso tawm ua hauj lwm nyob rau hauv ib txwm hom, txawm li cas los xij, thaum nws dhau lawm, lub qia raug thawb tawm ntawm lub solenoid. Nws, nyob rau hauv lem, rests tawm tsam bimetallic phaj, uas qhib kev sib cuag.

Cov qauv sab hauv ntawm lub tshuab
Cov qauv sab hauv ntawm lub tshuab

Cov kev tso tawm no cuam tshuam tsis yog rautam sim no overloads, tab sis kuj mus rau ib qho kev nce nyob rau hauv sab nraud kub, yog li tsis zoo stretched hu yuav ua rau lub sij hawm mus ncig ua si. Lawv kuj zoo rau kev kaw thaum muaj xwm txheej kub ntxhov. Tab sis qhov nthuav ntau ntawm cov hluav taws xob hluav taws xob hluav taws xob tuaj yeem hu ua RCD.

Cov khoom siv tam sim no: qhov sib txawv ntawm VA

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm RCD muaj cov haujlwm sib txawv kiag li. Muaj 4 qhov kev sib cuag ntawm rooj plaub, 2 ntawm cov uas yog rau cov tswv yim / tso tawm ntawm theem xaim, thiab 2 rau xoom ib qho. Cov khoom siv zoo li no ua haujlwm ntawm lub hauv paus ntsiab lus ntawm qhov sib txawv. Thaum lub sij hawm ib txwm ua haujlwm ntawm Circuit Court, theem nrog xoom yog sib npaug thiab RCD ua haujlwm hauv hom qub. Txawm li cas los xij, qhov dej me me ntawm tam sim no tsim qhov tsis sib xws, thiab cov cuab yeej txiav tawm. Kev tiv thaiv tib neeg, hom tshuab no zoo dua VA.

RCDs muab kev tiv thaiv zoo tiv thaiv tam sim no

Cia peb ua piv txwv qhov kev tawg ntawm ib theem xaim ntawm lub cev ntawm txhua yam khoom siv hauv tsev. Yuav luag txhua tus paub tias qhov kev xav tsis zoo li cas tshwm sim thaum kov cov hlau hauv qhov xwm txheej zoo li no. Hauv qhov xwm txheej no, sai li sai tau thaum tus neeg kov lub cuab yeej, RCD yuav tua lub zog, thiab cov tshuaj tiv thaiv ntawm lub cuab yeej nrawm dua li ntawm VA. Txawm li cas los xij, hom tshuab tsis siv neeg no tsis txuag los ntawm luv luv Circuit Court - nws tsuas yog tsis teb rau luv luv Circuit Court, txuas ntxiv mus ua haujlwm.

Rau cov neeg uas xav nkag siab txog kev ua haujlwm ntawm RCD kom ntxaws ntxiv, hauv qab no yog video luv.

Nws yuav tsum tau muab sau tseg tias ob hom kev sib tsoo hluav taws xob tau piav qhia saum toj no thiab ua haujlwmsib txawv kiag li, optimally ntsia hauv khub. Nws puas tuaj yeem tau txais los ntawm ib lub cuab yeej? Yog, yooj yim.

Difavtomat: nws yog dab tsi, nws ua haujlwm li cas?

Ntau zaus tib neeg tsis xav cuam tshuam nrog cov xaim ntxiv hauv lub txee hloov, thiab qee zaum tsuas muaj qhov chaw tsis txaus los nruab tag nrho cov kev tiv thaiv uas tau npaj tseg. Tom qab tag nrho, yog tias koj saib nws, ntawm DIN rail, RCD yuav siv 2 qhov chaw modular ntxiv rau lub Circuit Court breaker - tag nrho ntawm 3. Thiab yog tias muaj ntau pab pawg fais fab, ntxiv rau, nws yog ib qho tsim nyog yuav tsum tau mount ib qho kev taw qhia tso tawm., nruab ib lub ntsuas hluav taws xob? Nws hloov tawm tias koj yuav tsum tso cov khoom siv tiv thaiv? Ua tiav kev xaiv. Hloov chaw ntawm RCD thiab VA, lub difavtomat tau teeb tsa, uas sib txuas ua haujlwm ntawm ob lub khoom siv.

Cov cuab yeej no tuaj yeem ua haujlwm ntawm cov khoom siv tam sim no, luv luv lossis xau hauv Circuit Court. Hauv qhov loj me, nws zoo ib yam li RCD (2 qhov chaw), thiab qee zaum mus rau VA, uas nyob ib qho module. Feem ntau nws yog qhov tseem ceeb uas tau txiav txim siab thaum xaiv cov khoom siv, tab sis lub tshuab sib txawv kuj muaj nws qhov tsis zoo. Nws tus nqi siab dua li ntawm VA lossis cov khoom seem tam sim no, thiab yog tias ib qho ntawm cov khoom tsis ua haujlwm, koj yuav tsum tau yuav nws tag nrho, thaum qhov kev tso tawm tuaj yeem hloov pauv nyias.

Muaj kev sib cav ntau ntawm cov kws tshaj lij, dab tsi zoo dua - cais kev tiv thaiv lossis ua ke? Kev txiav txim los ntawm cov txheeb cais, muaj kwv yees li tib tus naj npawb ntawm cov neeg txhawb nqa ntawm difavtomats thiab lawv cov neeg tawm tsam. Thaum daws qhov noCov lus nug yuav tsum ua raws li qhov ua tau ntawm kev teeb tsa. Thiab yog tias xaiv lub tshuab sib txawv, koj yuav tsum tsis txhob txuag ntawm kev yuav khoom. Nws yog qhov zoo dua los yuav cov khoom lag luam zoo tshaj li niaj zaus hloov cov pheej yig.

Kev tiv thaiv kab hluav taws xob yog qhov tsim nyog, leej twg tau ntsib qhov teeb meem zoo sib xws yuav pom zoo nrog qhov no. Tab sis nws tsis txaus tsuas yog yuav cov khoom thawj zaug uas tuaj hla thiab txuas nws. Nws yog ib qho tsim nyog yuav tsum ua tib zoo xam tag nrho cov kev ntsuas tsim nyog, ntsuas qhov zoo thiab qhov tsis zoo ntawm kev cuam tshuam rau ib lossis lwm hom tshuab, thiab tsuas yog tom qab ntawd xaiv. Qhov ntau ntawm cov khoom siv tiv thaiv rau lub tsev hluav taws xob network yog qhov dav heev, uas txhais tau hais tias kev daws teeb meem yuav tsis yooj yim. Txawm li cas los xij, tsuas yog kev paub, kev xav thiab kev xaiv kom raug yuav pab tiv thaiv lub neej thiab kev noj qab haus huv ntawm cov neeg hlub, nrog rau kev nyab xeeb ntawm cov khoom.
