Cov khoom siv ntawm ib qho khoom siv ib txwm suav nrog clamps rau kev txhim kho ob lub cuab yeej lawv tus kheej thiab lwm yam kev tswj hwm, xws li cov keyboards. Muaj plaub yam tseem ceeb:
- apartment;
- group;
- main;
- pem teb hloov chaw.
Pab pawg cov cuab yeej muab kev tswj hwm ntawm qee pawg ntawm cov neeg siv khoom siv hluav taws xob. Lawv txoj haujlwm yuav tsum muaj cov hluav taws xob sib txuas, cov haujlwm uas tseem suav nrog kev kaw tag nrho ntawm cov khoom siv hluav taws xob yog tias tsim nyog.
Lub cuab yeej tseem ceeb hauv lub tsev lossis chav tsev sib cais ua qhov kev tawm tswv yim thiab kev sib txuas ntawm lub zog. Nws yog ib nqi sau cia hais tias nws yuav siv tau raws li ib tug suav ntaus ntawv, thaum lub sij hawm tom kawg ua hauj lwm nyob rau hauv lub xub ntiag ntawm ib tug nruab nrab tuag-earthed hlau. Lub luag haujlwm tseem ceeb yog txhawm rau tiv thaiv tam sim no thiabvoltage fluctuations.
Pem teb thiab chav tsev mechanisms zoo ib yam li pab pawg raws li lub hom phiaj. Cov neeg siv khoom hauv cov ntaub ntawv no yog ib lub tsev lossis cov khoom siv hluav taws xob muaj nyob hauv chav.
Cas
Txhua qhov yuav tsum tau ua thiab cov cuab yeej thev naus laus zis tau tsim los ntawm GOST rau kev tiv thaiv txhua yam. Ua tib zoo saib xyuas qhov tshwj xeeb ntawm kev ua haujlwm ntawm cov cuab yeej siv, lawv yuav tsum muaj kev tiv thaiv siab tiv thaiv hluav taws. Cov ntaub ntawv yog raws li cov ntaub ntawv uas tiv taus melting thiab tuaj yeem tiv taus qee qhov kub, uas txawv raws li lub hom phiaj kev nyab xeeb thiab kev tiv thaiv chav kawm.
Lub neej kev pabcuam yog 25 xyoo, thaum lub sijhawm ua haujlwm muaj peev xwm tiv taus lub zog nce mus txog 2500 watts. Cov kev xaiv kaw yog kev poob siab thiab cov neeg kho tshuab resistant.
Tsim qhov sib txawv
Hluav taws xob faib pawg tuaj yeem ua hauv pem teb, ua-hauv thiab nyiaj siv ua haujlwm. Cov tom kawg yog tsau rau ntawm phab ntsa cov qauv, cov kev xaiv built-in - nyob rau hauv tshwj xeeb tsim niches, lawv yog optimally suited rau kev tiv thaiv lub tsev. Cov chav hauv pem teb yog qhov loj thiab, raws li lub npe qhia, tau kho rau hauv pem teb.
Tseem muaj cov cuab yeej nqa tau yooj yim uas siv los ntawm cov kws tshaj lij rau kev mus ncig ua si. Lawv muaj cov yam ntxwv zoo ib yam li cov txheej txheem sib xyaw thiab txuas nrog cov tshuab tsis siv neeg. Lub teeb taw qhia qhia lub ntsiab lus ntawm qhov voltage hauv lub mains.
Txhim kho nta
Kev teeb tsa ntawm lub tshuab hluav taws xob yuav tsum tau kos duab ua ntej ntawm daim duab, kev xaiv ntawm cov hlua siv, lub ntsiab lus ntawm cov cuab yeej tiv thaiv, cov tshuab tsis siv neeg thiab cov khoom ntxiv. Nws yog ib qho tseem ceeb uas yuav tsum tau xyuam xim tshwj xeeb rau qhov haujlwm no thiab tsis txhob poob qhov pom ntawm ib qho twg.
Ua ntej tshaj plaws, tag nrho lub zog ntawm cov neeg siv khoom siv hluav taws xob uas muaj nyob hauv tsev lossis chav tsev yog txiav txim siab. Cov chaw, nyob ntawm lub hom phiaj, muab faib ua pawg, piv txwv li, chav nyob, chav ua noj thiab lwm yam. Nyob rau hauv txhua cheeb tsam, tus nqi ntawm lub zog siv yog xam. Yog tsis muaj cov ntsuas no, nws tsis tuaj yeem xaiv lub npe nominal ntawm lub Circuit Court breaker. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum coj mus rau hauv tus account qhov muaj peev xwm ntawm cov khoom hnyav uas tshwm sim thaum lub sijhawm ua haujlwm ib txhij ntawm cov khoom siv ntau thiab tuaj txog ntawm cov qhua lossis cov txheeb ze. Lub teeb pom kev zoo tsim nyog tau txais kev saib xyuas tshwj xeeb, raws li nyob ntawm cov xwm txheej ntawm kev thauj khoom, ib qho kev tsim nyog cable nrog rau qhov yuav tsum tau hla ntu raug xaiv.
Kev sib txuas tuaj yeem ua tau ntau txoj hauv kev: "hnub qub", "loop", lub thawv lossis tus kheej tsim saib. Tus naj npawb ntawm cov xaim tawm yog nyob ntawm cov xaim uas twb muaj lawm, nws tuaj yeem ncav cuag li 20-30 daim. Nyob rau hauv rooj plaub no, txoj kev txiav tawm yog xaiv raws li cov neeg siv khoom siv hluav taws xob uas twb muaj lawm thiab lawv qhov chaw nyob. Rau qee cov khoom siv nrog kev siv siab, cais RCDs raug teeb tsa.
Lwm qhov sib txawv
Shieldkev faib tawm tuaj yeem tsim rau ob qho tib si sab hauv tsev thiab sab nraum zoov. Cov yam ntxwv sab nrauv tsis cuam tshuam rau kev ua haujlwm thiab raug xaiv raws li tus kheej nyiam thiab tag nrho cov qauv tsim. Cov ntaub ntawv tuaj yeem ua los ntawm hlau lossis yas, nruab nrog lub qhov rooj pob tshab lossis opaque.
Cov chav sab nraum zoov yog tsim rau cov pob zeb ua vaj tse ntxiv vim lawv tsis xav tau qhov drilling. Embedded xaiv yog qhov zoo tshaj plaws rau cov phab ntsa ntub dej. Tus naj npawb ntawm cov cuab yeej tau teeb tsa hauv lub vaj huam sib luag cuam tshuam rau nws qhov ntev, thaum lawv yuav tsum sib haum rau qhov dav ntawm qhov module uas twb muaj lawm.
Txhim kho ntawm switchboard
Rau mounting rau sab nrauv phab ntsa, screws thiab dowel-nails yog siv. Lawv kuj tuaj yeem siv los kho lub thawv sab hauv nrog kev kho ntxiv nrog alabaster sib tov lossis gypsum-raws li kua nplaum.
Kev xaim ua tiav tom qab kho lub cuab yeej, nrog rau kev txhim kho cov khoom tsim nyog.
Lub switchboard hauv tsev, uas muaj DIN rails, tshwj xeeb tshaj yog yooj yim. Qee cov qauv tau nruab nrog cov ntsiab lus tshwj xeeb rau kev kho lawv, thiab tom qab kev teeb tsa, cov khoom sab hauv yog tsau nrog cov latches tshwj xeeb nyob rau sab nraub qaum. Nws kuj tseem tuaj yeem kho qhov ntsuas ntawm DIN ntsia hlau, ntsia hlau lossis ntsia hlau yog tias muaj qhov tshwj xeeb rau nws.
Kev teeb tsa lub tshuab hluav taws xob tsis tas yuav tsum muaj kev txawj tshwj xeeb: lawv tau teeb tsa rau ntawm txoj kev tsheb ciav hlau kom txog thaum tus yam ntxwv nyem tshwm, qhianruj fixation. Yog tias tsim nyog tshem tawm cov khoom uas twb muaj lawm, siv lub hau ntswj rub tawm lub qhov muag ntawm lub tshuab thiab tshem tawm ntawm qhov txuas.
Yam uas koj yuav tsum paub
Ua ntej kev teeb tsa, koj yuav tsum tau txais kev tso cai los ntawm kev pabcuam hluav taws xob. Qhov kev xaiv zoo tshaj plaws yuav yog los ua haujlwm raws li kev saib xyuas ntawm tus neeg sawv cev ntawm cov khoom siv hluav taws xob. Yog tias qhov kev teeb tsa raug kuaj pom hauv qhov chaw tsis tsim nyog, tus kws tshaj lij hluav taws xob yuav tsum raug hu, nws yuav kuaj xyuas qhov tseeb, qhov zoo ntawm kev sib txuas, thiab kaw lub ntsuas. Txhua lub koom haum yuav tsum tau daws raws sijhawm, txwv tsis pub yuav raug nplua.
Hom ntsuas ntsuas tau tswj hwm los ntawm lub koom haum uas muab hluav taws xob. Txawm li cas los xij, cov txiaj ntsig tau qhia ntawm lub cuab yeej yuav tsum tsis pub tshaj.
Kev sib txuas ntawm cov cuab yeej suav nrog hauv kev tsim tsis muaj teeb meem, koj tsuas yog yuav tsum tau ceev faj thiab ua haujlwm raws li cov tswv yim. Thaum txhim kho lub switchboard, nws yog undesirable kom maj mus txuas rau nws, nws yog ib qho tseem ceeb kom paub tseeb tias tag nrho cov kev ua thiab kev sib txuas tau ua kom raug.
Txoj kab
Qee cov xov hlau yuav tsis xav tau hauv av, cov no feem ntau yog cov khoom siv hluav taws xob teeb pom kev zoo. Thaum siv cov teeb fluorescent nyob sab hauv tsev nrog kev sib cuag hauv av, nws yog ib qho tsim nyog los txuas lub tsheb npav hauv av nrog tus neeg xyuas pib, thiab tseem nqa peb lub xaim xaim.
Cov khoom xa tuaj thiab xaim ua rau thaj chaw fais fab txuas tom qab kev sib txuaskhoom siv. Nws yog tsim nyog sau cia qhov yooj yim ntawm kev xaiv lub hom phiaj ntawm ib qho cuab yeej tshwj xeeb ntawm txhua tus ntawm lawv. Qee cov khoom siv tau nruab nrog lub qhov rais tshwj xeeb, nyob rau hauv lawv qhov tsis tuaj, koj tuaj yeem muab cov cim rau ntawm lub hau ntawm sab hauv ntawm cov qauv. Lub switchboard yog switched rau tom qab tag nrho cov hauj lwm tau ua tiav siv ib tug general switching. Ntxiv mus, siv qhov taw qhia, qhov kev ntseeg siab ntawm lub zog ntawm txhua lub xaim raug kuaj xyuas.
Recommendations
Kev siv ib qho RCD yog qhov tsis xav tau rau ntau yam khoom siv rau ntau lub hom phiaj sib txawv, ua ke rau hauv ib pab pawg, vim tias qhov tsis ua tiav ntawm ib qho ntawm lawv tuaj yeem ua rau luv luv ntawm lwm tus. Cov chaw yuav raug muab faib ua ntau thaj chaw nrog lawv tus kheej RCDs; thaum xaiv qhov tom kawg, nws tsim nyog muab qhov kev nyiam tsis yog rau hauv hluav taws xob, tab sis rau cov khoom siv kho tshuab, vim nws muaj kev ntseeg siab dua. Nws tuaj yeem muab cov khoom siv los ntawm chav dej, thiab chav ua noj thiab qhov chaw nyob tau muab faib ua ob pawg.
Cov keyboard hloov tau xaiv nrog cov npoo kom tiv thaiv nws qhov kev hloov ntxov ntxov thaum ntxiv cov khoom siv.
Qhov kev xaiv zoo tshaj plaws yog txhawm rau txhim kho RCD cais rau txhua qhov chaw, tab sis qhov no tsis yog ib txwm muaj kev ncaj ncees nyiaj txiag. Thaum tsis muaj cov cuab yeej muaj zog hauv tsev, nws tuaj yeem nqa ntau lub tshuab hauv qab ib RCD.
