Yuav ua li cas yuav ua rau ib qho kev xaiv seem ntawm lub cable?

Niaj hnub no muaj peev xwm rightly yuav hu ua lub era ntawm kho: lub tsev tshiab tsev, thiab feem coob ntawm cov uas twb muaj lawm vaj tse muaj kev koom kho. Qhov no yog tshwj xeeb tshaj yog muaj tseeb rau cov private sector vaj tse, lub tsev nyob rau hauv ntau ntawm lub 50s rau hauv lub 80s. Siv tau nyob rau lub sij hawm cov ntaub ntawv twb yog cov poob lawv lub zog vim lub ntuj laus, cov tau kev hloov ntawm cov av coj mus rau ib tug kab sib chaws ntawm tej kab nrib pleb rau ntawm cov phab ntsa, thiab lwm yam .. Nyob rau hauv tas li ntawd, cov kev hloov tsim txoj kev thiab, tseem ceeb tshaj, yog ntau dua uas yuav tsum tau mus rau lub haumxeeb qauv. Piv txwv li, yog tias ua ntej cov kev xaiv ntawm cable ntoo khaub lig-section ntawm lub load thaum ua tsev neeg thaiv tau ua rau lub hauv paus ntawm tag nrho cov tau ntawm tsis muaj ntau tshaj li 1-1.5 kilowatts, tab sis tam sim no cov qhov tseem ceeb yog ho muaj zog. Tam sim no yog tsawg kawg admissible 3 kilowatts (tam sim no nyob rau hauv Ampere 16). Yog li, ob qho tib si nyob rau hauv private tsev thiab qhov yuav tsum tau nyob rau hauv raws li cov tshiab yuav tsum tau, mus nqa tawm kev xaiv ntawm lub cable ntoo khaub lig-seem thiab hloov tag nrho thaiv. Peb tsis yog nyob rau hauv vain nyob rau hauv thaum ntxov kho yam kov: qhov tseeb hais tias feem ntau ntawm cov kev yog tug hloov rau sab hauv kho kom zoo nkauj. Yuav kom nteg ib tug tshiab cable, feem ntau nyob rau hauv cov phab ntsa Stroebe ua li cas. Ntawm cov hoob kawm, koj muaj peev xwm siv lub plinth nrog cable channel thiab yas thawv, tab sis cov tshuaj no yog tsis haum rau txhua txhua sab hauv.

Raws li cov kev xaiv yog ua seem ntawm lub cable? Wb hais tam sim ntawd: qhov no yog tsis muaj big deal. Cov neeg ua hauj lwm lis txawm tias ib tug schoolboy. Koj yuav tsum los zaum nrog ib tug cwj mem thiab ib daim ntawv ntawm daim ntawv, ua ib daim ntawv teev cov feem ntau haib zog tau txais kev pab thiab rau kev tsom xam uas cov yuav yuav zes ib txhij. Cia saib ib tug piv txwv yooj yim ntawm yuav ua li cas yuav ua rau ib tug ntau yam ntawm cable ntau thiab tsawg pab.

Muaj yog ib tug neeg ua hauj lwm - mus connect rau lub fais tshuab ntxhua khaub ncaws. Qhov kev xaiv ntawm cable ntoo khaub lig-section pib nrog ib qho kev xeem ntawm passport cov ntaub ntawv ntawm tus dais - yuav tsum nrhiav tau tus nqi ntawm lub hwj chim noj. Txij li thaum nyob rau hauv kev sib raug zoo rau cov cav tov manufacturers ib tug me ntsis lo qhia, koj yuav tsum ua tib zoo txoj kev ua tus teeb meem. Nws hais tias: "Hwj chim - 200 Watts". Txawm li cas los, hauv qab no koj yuav nrhiav tau ib tug hais txog ntawm tus yam ntxwv ntawm lub caij cua kub. Rau nws yog hais rau 2 kW. Yog li, nyob rau hauv tus nqi ntawm cov tshuab kov 2.2 kW. Nws yog ib qho tseem ceeb yuav coj account ntawm xws "trifles", los yog incorrectly xaiv cable tsuas hlawv. Nws seem ua tus xaiv seem ntawm lub hwj chim cable.

Nruab nrab ntawm lub tam sim no thiab lub hwj chim nqi yog ib tug ncaj qha kev sib raug zoo. Cov mis yog:

P = U * Kuv,

qhov twg P - hwj chim; U - voltage; I - tam sim no.

Cov tsev neeg hwj chim ua ntej tshaj qhov ntawm 220 volts.

Kawm txog cov nqi ntawm lub hwj chim lub tshuab (2,2 kW), nws yog tsim nyog rau saum toj no mis nyuj tov rau xam cov tam sim no:

I = 2200 W / 220 = 10 Amperes

Cov nram qab no siv saib-up lub rooj, uas muab raws li cable neeg xyuas pib khoom, nws tus ntoo khaub lig seem, tso txoj kev (qhib, nyob rau hauv ib tug raj nyob rau hauv lub phab ntsa) thiab tam sim no tus nqi. Ntxhuav yog muab nyob rau hauv phau ntawv "kev cai rau Hluav taws xob cov Installation." Lawv muaj peev xwm kuj yuav pom nyob rau hauv lub ntiaj teb no network - cov ntaub ntawv no yog laj mej pej xeem muaj. Nyob rau hauv cov ntaub ntawv no, yog hais tias tus "noj" ntawm tooj liab nyob ntawm tej, lawv seem yuav tsum tau muaj yam tsawg 0.75 square meters. hli (tam sim no nyob rau hauv Ampere 15 rau qhib xov). Ntawm cov hoob kawm, tus 30% paj tau paj yog ntev li, tab sis txij li thaum lub hlau yog tsis nquag positioned qhib, lub pub tam sim no yog tsawg dua. Tsis tas li ntawd, tom ntej no sab seem (0.5) yog tsim los rau 11 amps, uas yog tsis txaus.

Nyob rau hauv lub xaiv ntawm lub tsev postings siv tib lub hauv paus ntsiab lus. Qhov txawv yog tias koj yuav tsum coj mus rau hauv tus account lub sum ntawm lub hwj chim ntawm pab kiag li lawm uas yuav tau ib txhij siv thaum twg ceg.
