Lub sijhawm los txog thaum cov hluav taws xob qub hauv chav tsev lossis lub tsev ntiag tug yuav siv tsis tau. Yog vim li cas rau qhov no yog lub sij hawm, tshwj xeeb tshaj yog cuam tshuam rau txhuas cables. Tsis tas li ntawd, tus naj npawb ntawm cov khoom siv hauv tsev ntau zuj zus uas thauj cov khoom siv hluav taws xob hauv tsev tuaj yeem dhau los ua qhov laj thawj rau kev xav tau hloov pauv. Thaum hloov kho nws, koj yuav tsum tau ua qee qhov kev suav txhawm rau txiav txim siab qhov zoo tshaj plaws hlau hla ntu rau cov qhov (socket). Qhov no yuav tsum tau ua rau koj tus kheej kev nyab xeeb. Hnub no tsab xov xwm yuav qhia txog cov kev suav no.
Vim li cas thiaj suav hla ntu thiab xaiv kab twg
Cov khoom siv hlau ua lub luag haujlwm tseem ceeb heev. Cov khoom siv txhuas yuav raug nqi tsawg dua, tab sis nws yuav tsum nkag siab tias qhov no koj yuav tsum tau yuav cov cores nrog qhov loj hla ntu, yogthiab kev pabcuam lub neej yuav tsawg dua li cov tooj liab. Nws yog rau cov laj thawj no uas cov kws tshaj lij qhia siv cov cables kim dua.
Kev suav ntawm cov xaim hla ntu rau cov sockets hauv ib chav tsev yog qhov tseem ceeb rau kev ua haujlwm ntawm lub zog hauv tsev, tsis muaj cua sov ntawm cov cores thaum lub sijhawm ua haujlwm. Cables uas nyias dhau yuav tsis tiv taus lub load thaum tig rau ntau yam khoom siv hauv tsev. Ntau tus yuav hais tias nws yog qhov zoo dua los yuav cov hlau tuab, txawm li cas los xij, kuj muaj qhov tsis zoo ntawm no. Ib qho kev hla ntau dhau ua rau tsis muaj txiaj ntsig ntawm kev siv nyiaj txiag thiab kev siv zog thaum lub sijhawm teeb tsa - nws yuav nyuaj dua rau lawv.
Yuav ua li cas xam seem: cov cai yooj yim
Ua ntej koj pib xam, koj yuav tsum rov sau tag nrho cov ntaub ntawv ntawm kev siv hluav taws xob ntawm cov khoom siv hluav taws xob hauv tsev. Nyob rau hauv cov ntaub ntawv no, nws yog tsim nyog los xam tsis tau tsuas yog tag nrho cov noj nyob rau hauv lub chav tsev, tab sis kuj yog ib tug qhia rau ib tug neeg chav. Qhov no yog qhov tsim nyog los txiav txim seb muaj pes tsawg kab uas yuav raug coj mus rau hauv qhov chaw. Piv txwv li, koj tuaj yeem nqa ib chav tsev nrog 4 chav. Hauv qhov no, cov kab yuav raug faib raws li hauv qab no:
- Khoom sockets.
- Chav nyob nrog tsev ua yeeb yam, khoos phis tawj thiab suab kaw hauv nws.
- Ob chav pw thiab ib chav nkag - tsis muaj qhov tshwj xeeb ntawm lub qhov hluav taws xob.
Nuances ntawm kev suav rau ntau yam khoom
Yog tias, thaum ntxiv cov khoom siv hluav taws xob nyob ntawm tib kab,Qhov ntsuas tau tsawg dua 3 kW, tom qab ntawd cov kev suav ntxiv tuaj yeem raug tshem tawm - qhov no, nws yuav yog qhov zoo tshaj plaws los siv cov ntu ntu ntawm tooj liab, sib npaug li 2.5 hli 2. Tshaj 3 kW yuav tsum suav ntxiv.
Cov ntaub ntawv tseem ceeb! Lub bandwidth ntawm tooj liab thiab txhuas cables txawv. Hauv thawj kis, nws yuav yog 10 A / mm, hauv qhov thib ob 8 A / mm. Cov ntaub ntawv no yog qhov tsim nyog thaum xam cov xaim hla ntu rau cov sockets.
Xaiv ntawm cable hla ntu ntu siv piv txwv ntawm chav ua noj puv ntoob
Raws li qhov tseeb tias muaj ntau yam khoom siv hauv chav tsev, nws yuav tsum nkag siab tias cov xov hlau yuav tuab dua li cov uas haum rau chav nyob. Chav ua noj yog nruab nrog cov khoom siv hauv qab no (qhia lub zog hauv watts):
- toaster - 1000;
- kas fes - 1000;
- hluav taws xob hluav taws xob - 1000;
- cua - 1500;
- hluav taws xob qhov cub - 2500;
- tub yees - 500;
- Microwave cub - 750.
Tam sim no koj yuav tsum nkag siab qhov seem ntawm cov xaim rau qhov yuav tsum tau ua. Txhawm rau ua qhov no, ntxiv cov ntsuas hluav taws xob thiab faib cov txiaj ntsig tau los ntawm lub zog hluav taws xob. Peb tau txais 8250/220=37.5 A. Qhov no yuav yog cov khoom siv tam sim no siv.
Tam sim no xaiv cov khoom ntawm tus neeg xyuas pib. Thaum siv tooj liab, peb ua raws li cov lus qhia nram qab no: peb ntxiv cov npoo hauv daim ntawv ntawm 5 A, tom qab ntawd peb tau txais (37, 5 + 5) / 10=42, 5/10=4, 25. Qhov no txhais tau tias cov lus teb. mus rau lo lus nug ntawm dab tsi seem yuav tsumhlau rau cov qhov (socket) nyob rau hauv xws li ib tug load, yuav yog 4.5 mm2.
Power Distribution Cabinet Equipment
txhawm rau xam qhov tsis raug ntawm kev tiv thaiv automation, koj yuav tsum tsis yog tsuas yog siv lub zog ntawm cov khoom siv hluav taws xob hauv tsev xwb, tab sis kuj muaj teeb pom kev zoo, uas yuav tsum tau siv los ntawm ib lossis ob pawg sib cais. Feem ntau, qhov no yog kev faib cov chav tsev rau hauv cov kab "chav pw / chav ua noj / chav tsev" thiab "chav nyob / menyuam yaus / da dej / chav dej". Ntawm no, nrog cables, txhua yam yog yooj yim heev. Hauv cov tsev niaj hnub, nws tsis tshua pom muaj teeb pom kev zoo halogen nrog kev siv hluav taws xob ntau ntxiv - niaj hnub no LEDs tau siv ntau dua. Yog li ntawd, yog hais tias cov lus nug ntawm dab tsi seem ntawm hlau yuav tsum tau rau lub qhov (socket) yog ib qho tseem ceeb, ces txhua yam yog theem pib nrog teeb. Feem ntau, cov kab tooj liab ntawm ib thiab ib nrab squares yog siv rau cov kab teeb pom kev zoo.
Cable markings siv nyob rau hauv domestic fais fab network
Thaum yuav ib lub cable, koj yuav tsum tau xyuam xim rau nws cov rwb thaiv tsev. Nws tsis tuaj yeem txiav txim siab qhov pom ntawm nws cov muaj pes tsawg leeg, txawm li cas los xij, txhua qhov tsis tuaj yeem pom los ntawm cov cim, uas muaj ob peb tsab ntawv thiab cov lej qhia tus naj npawb ntawm cov cores thiab ntu ntu ntawm cov xaim. Rau lub qhov (socket), qhov kev xaiv zoo tshaj plaws yuav yog 3 × 2, 5. Tab sis nws tsim nyog nyob ntawm cov ntawv sau kom ntxaws.
VVG - polyvinyl chloride rwb thaiv tsev hauv 2 txheej. Xws li ib tug tooj liab hlau yog zoo meej rau lub qhov hluav taws xob, tab sis nws yuav tsum nco ntsoov tias nws tsis muaj peev xwm ua rau nws tus kheej attenuate.
VVGng - tib lub cable, tab sis twb nyob rau hauv tsis-combustible rwb thaiv tsev, raws li lawv hais2 tsab ntawv kawg.
VVGng-LS yog cov kab hluav taws xob uas tsis yog hluav taws xob hauv PVC, uas tsis kis cov pa phem thaum raug kub hnyiab. Feem ntau siv nyob rau hauv preschool thiab lwm lub tsev kawm ntawv.
tsab ntawv NYM qhia txog ntau yam kim dua ntawm German-ua VVGNG.
Yog tias tsab ntawv "A" (AVVG, AVVGng) nyob rau hauv pem hauv ntej ntawm cov npe teev, qhov no txhais tau hais tias cov cables yog ua los ntawm txhuas.
Qhov tshwm sim ntawm kev xaiv qhov tsis raug xaim loj rau qhov hluav taws xob
Yog tias koj tsis quav ntsej cov lus qhia ntxaws ntawm qhov ntsuas no, tom qab ntawd koj tuaj yeem khuv xim nws heev. Raws li qhov tshwm sim ntawm kev ua li no, tib neeg poob lawv cov khoom, thiab qee zaum lawv lub neej. Tau kawg, ntau nyob ntawm kev tiv thaiv automation nyob rau hauv lub inlet faib txee, tab sis nws yuav tsis zoo li hais tias tus neeg uas tsis them nyiaj mloog mus rau lub thickness ntawm lub cable yuav muaj peev xwm xaiv qhov zoo thaum muaj xwm ceev kaw khoom.
Hla me me ntawm cov xaim rau lub qhov hluav taws xob nyob rau hauv siab load ua rau nws cov cua sov. Qhov tshwm sim ntawm kev ua haujlwm ntxiv yog qhov hluav taws xob ntawm lub cable, vim tias qhov hluav taws xob rwb thaiv tsev kub hnyiab tawm thiab qhov hluav taws xob luv luv tshwm sim. Feem ntau, los ntawm lub sij hawm no, lub tsev twb engulfed nyob rau hauv hluav taws, yog li ntawd lub triggered tshuab tsis daws tau dab tsi. Yog hais tias cov partitions nyob rau hauv lub tsev yog ntoo, 2-3 feeb yog txaus rau tag nrho lub tsev kom blaze. Thiab nws tsis yog qhov tseeb tias qhov no yuav tsis tshwm sim thaum hmo ntuj, thaum sawv daws tsaug zog. Thaum zoo li no, tsis tshua muaj leej twg tawm tau.
Ntxivphom thiab txee rooj tog. Thaum lub cable ignites, txawm nyob rau hauv cov qhob partitions, theem ntawm kub nce yog heev txaus ignite lub wallpaper, ua raws li los ntawm lub txee dai khaub ncaws, uas yog ntsia ze rau ntawm phab ntsa. Tsis tas yuav tham txog cov pa luam yeeb los ntawm lub chipboard blazing.
Cov lus xaus ntawm cov ntaub ntawv muab
Txawm hais tias tus neeg niaj hnub no tsis tuaj yeem xav txog lub neej tsis muaj hluav taws xob, nws tuaj yeem hu ua qhov txaus ntshai heev. Tab sis cov lus no muaj tseeb tsuas yog tias txoj hauv kev rau nws siv tsis raug. Dab tsi hlau seem rau cov qhov (socket) yuav raug xaiv yog nyob ntawm tus tswv tsev txiav txim siab. Qhov tseem ceeb tshaj plaws yog tias tag nrho cov kev suav tsim nyog tau tsim, thiab cov kab hluav taws xob tsis tig los ua nyias dua li qhov xav tau. Pom los ntawm lub kaum sab xis no, cov xov hlau tuab, txawm tias nyuaj rau nruab, muab cov khoom siv hluav taws xob txhim khu kev qha, tshem tawm qhov kev pheej hmoo ntawm overheating thiab ignition.
