Xaiv lub zog ntawm lub zog hluav taws xob yog lub hauv paus rau nws txoj haujlwm ib txwm muaj. Rau kev xav tau hauv tsev, qhov hluav taws xob ntawm 220 volts feem ntau yog siv. Tab sis tus nqi no tsis yog ib txwm txaus rau kev ua haujlwm ntawm txhua yam khoom siv hluav taws xob uas siv hluav taws xob. Muaj ntau zaus thaum nws tsim nyog los hloov tus qauv voltage nrog qhov siab dua - 380 volts.

Txoj kev sib txawv network

Kev muab khoom ntawm tus qauv hluav taws xob network npaj rau cov kev xav tau hauv tsev muaj nyob rau hauv kev tso ob lub cores - nrog rau kev thauj khoom thiab xoom. Hauv qhov no, qhov hluav taws xob tshwm sim ntawm lawv yog 220 volts. Qhov no yog qhov txaus los xyuas kom meej qhov kev ua haujlwm ib txwm muaj ntawm cov khoom siv hauv tsev thiab cov teeb pom kev zoo. Tab sis thaum lub load nce, lub hwj chim cable heats li, uas yuav inevitably ua rau ib tug luv luv Circuit Court los yog hluav taws kub.

Txhawm rau zam qhov xwm txheej hauv chav, nws yog qhov yuav tsum tau nteg tsis yog ib qho, tab sis 3 cores. Feem ntau ntawm cov xwm txheej, qhov no tau muaj nyob hauv cov tsev apartment. Rau kev lag luam ntiag tug, xws li kev sib txuas tsuas yog ua tau yog tias muaj kab nyob zeCov kab sib txuas nrog peb ntu sib cais. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum tau tso cai los ntawm lub tuam txhab tswj hwm thiab xyuas kom muaj kev teeb tsa ntawm 4-core txuas hauv chav.

Thaum twg koj xav tau 380 volts

Qhov xav tau los txuas 3-theem voltage tuaj yeem tshwm sim los ntawm ntau qhov xwm txheej. Nyob rau hauv lub xub ntiag ntawm cov cuab yeej tshwj xeeb (muaj zog) lossis faib cov khoom thauj hauv lub network.

Muaj qee qhov kev faib tawm ntawm cov xov tooj hluav taws xob uas nws tuaj yeem hloov pauv tus nqi ntawm cov theem:

  • tsev ntiav lossis tsev.
  • Chaw tsim khoom lossis chaw ua lag luam nrog cov hluav taws xob dav dav.

Hauv kev xyaum, nws muaj teeb meem heev kom ua tiav yam tsawg kawg ib ntus ntawm qhov hluav taws xob nce mus rau qib uas yuav tsum tau muaj hauv chav tsev lossis tsev. Yog tias koj xav tau txuas 380 volts, ces koj xav tau qhov laj thawj zoo. Rau kev tsim khoom, 3-theem voltage feem ntau yog muab rau txawm tias nyob rau theem tsim. Qhov no yog vim lub zog siab ntawm cov cuab yeej thiab cov khoom thauj tsis tu ncua ntawm lub network.

Private houses and apartments

Thaum tsim cov tsev tsev, suav cov hluav taws xob siv tau ua tiav. Raws li cov ntaub ntawv no, xaim ntawm seem tsim nyog thiab cov khoom siv kev nyab xeeb raug teeb tsa. Yog tias, vim li cas, muaj kev siv hluav taws xob ntau ntxiv, nws raug nquahu kom txuas 380 volts.

zog 380v

Qhov no yuav yog vim muaj cov hauv qab no:

  • Kev txhim kho cov khoom siv hauv tsev muaj zog - cua sov boiler, kev tswj hwm huab cua, thiab lwm yam.
  • Kev kho ib ntus uas yuav ua rau muaj kev siv hluav taws xob ntau ntxiv thiab ua rau lub cev nce ntxiv.

Raws li qhov no, kev tso cai yog muab rau kev hloov pauv ib ntus lossis mus tas li hauv cov kev txwv tsis sib xws, uas qhov voltage ntawm 380 volts yuav dhau los ua qhov tseem ceeb.

txheej txheem rau kev tso daim ntawv tso cai

Muaj qee cov cai rau kev hloov pauv qhov tam sim no tsis muaj nyob hauv lub ntsiab. Txhawm rau kom tau txais daim ntawv tso cai, thawj theem, cov ntaub ntawv ua haujlwm raug kos. Nws qhia txog cov khoom siv thiab lawv cov yam ntxwv. Raws li cov ntaub ntawv no, lub tuam txhab tswj hwm yuav tsum muab cov txheej txheem rau qhov hluav taws xob ntawm 380 volts. Yuav txuas li cas thiab cov kab hluav taws xob twg yuav tsum tau siv rau qhov no, tus kws tshaj lij txiav txim siab.

380 volt yuav ua li cas txuas
380 volt yuav ua li cas txuas

Tom qab ntawd, ib qho kev coj ua, uas qhia cov ntsiab lus hauv qab no:

  • Yuav tsum tau ntim cov ntaub ntawv rau cov tswv ntawm ib chav tsev (tsev).
  • Technical design said above.
  • Ib daim ntawv qhia raws li kev tshuaj xyuas ntawm cov khoom siv thiab cov ntaub ntawv nrog rau cov neeg sawv cev ntawm tuam txhab.

Yog tias qhov yuav tsum tau ua kom ncaj ncees - qhov tseem ceeb ntawm kev siv hluav taws xob raws li cov qauv hauv cov ntawv pov thawj khoom, ces 380 volts tau muab thiab txuas.

Rau tsev ntiav, cov txheej txheem sib txawv me ntsis. Yog hais tias nyob deb ntawm tsawg kawg yog 500 m ntawmcov tuam tsev muaj 3-theem kab, tom qab ntawd tag nrho cov kev ua haujlwm ntawm nws qhov kev sib txuas (tom qab kev pom zoo ntawm cov ntawv tso cai) yog ua los ntawm cov tuam txhab tswj hwm. Txwv tsis pub, nws tsis tuaj yeem nce qhov hluav taws xob hauv tsev.

kev lag luam thiab kev lag luam siv

Rau cov tsev thiab cov qauv nrog cov khoom hnyav tas li, qhov hluav taws xob ntawm 380 volts yog teem los ntawm lub neej ntawd. Qhov no ncaj qha siv rau tag nrho cov chaw lag luam thiab kev lag luam. Rau cov khoom siv hluav taws xob ib txwm muaj, cov phiaj xwm muab cov txheej txheem rau kev saib xyuas thiab faib hluav taws xob nyob ntawm qhov chaw thauj khoom hauv ib cheeb tsam. Muab tso ua ke ntawm cov ntaub ntawv no yog ua los ntawm cov tuam txhab tshwj xeeb uas yuav tsum tau lees paub.

Puas tsim nyog ua txoj kab 3-theem mus rau tsev ntiav lossis chav tsev ua ntej? Qhov no tsuas yog ua tau yog tias cov kev cai tsim tau pom, uas yuav tsum tau qhia txog cov khoom siv hluav taws xob thiab lawv cov yam ntxwv.
