Transformer substations yog ib feem tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no. Lawv tau siv nyob rau theem ntawm kev faib hluav taws xob, tso cai rau txo qis cov txheej txheem ntawm distortion ntawm cov yam ntxwv tam sim no thaum nws kis tau mus ntev. Muaj ntau hom khoom xws li, uas txawv ntawm cov yam ntxwv ntawm kev tsim, mus kom ze rau kev teeb tsa thiab kev ua haujlwm. Nyob rau hauv lem, lub mast transformer substation yog feem ntau cov qauv ntawm no hom, muab ib tug xov tooj ntawm zoo.

Cov ntaub ntawv dav dav txog mast substation

Mast, lossis ncej, substation yog tsim los ua ib chav tsev transformer, uas, nyob ntawm tus yam ntxwv, tuaj yeem ua haujlwm nrog lub zog ntawm 25-250 kVA. Thaum lub sijhawm ua haujlwm, xws li kev teeb tsa tuaj yeem, qhov nruab nrab, tau txais AC hluav taws xob nrog qhov ntsuas hluav taws xob txog li 6 kV. Nrog rau kev txhim kho kom zoo, tus ncej transformer substation muaj peev xwm tswj tau qhov kev ua tau zoo ntawm ob qho tib si hauv cov huab cua sov thiab qhov kub thiab txias thaum lub caij ntuj sov.

phom sij heevsawv cev rau kev hem thawj ntsig txog kev ua haujlwm ncaj qha ntawm cov khoom zoo li no. Raws li kev khiav hauj lwm tej yam kev mob, tej zaum yuav muaj kev pheej hmoo ntawm luv luv circuits, kab overloads, theem-rau-theem tsis ua hauj lwm thiab overvoltages. Vim li no, twb nyob rau hauv qhov yooj yim configuration, mast transformer substation yog nkag nrog ntau yam kev tiv thaiv systems. Tsis tas li ntawd, cov khoom siv hluav taws xob thiab cov khoom siv sib cuam tshuam los xyuas kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm pabcuam.

Kev tsim ntawm mast substation

Qhov kev ua haujlwm ntawm lub tshuab hluav taws xob substation yog cuam tshuam nrog kev xav tau los txo qhov poob hauv cov kab hluav taws xob. Txoj haujlwm no tuaj yeem ua tiav hauv ntau txoj hauv kev, tab sis qhov no, kev teeb tsa yuav tsum muab qhov nce ntawm qhov voltage hauv lub network. Rau qhov no, lub substation yog muab nrog ib qho hluav taws xob kev teeb tsa uas ua haujlwm ntawm kev hloov pauv thiab faib hluav taws xob. Lub workflow muaj ob peb yam, nrog rau switchgears, tswj systems thiab auxiliary mechanisms uas muab cov dej num ntawm kev txhawb nqa lub lag luam ntawm tus qauv nws tus kheej. Ib zaug ntxiv, nyob ntawm daim ntawv thov thiab kev ua haujlwm, kev faib hluav taws xob hluav taws xob los ntawm lub chaw nres tsheb mast tuaj yeem tshwm sim nrog cov yam ntxwv sib txawv ntawm lub zog hluav taws xob. Tsis tas li ntawd, qee cov qauv muab rau kev ua haujlwm ntawm kev suav nyiaj rau hluav taws xob. Nws ua tiav siv cov txee ua ntej uas tuaj yeem ua haujlwm ob qho tib si ntawm lub hauv paus ntsiab lus ntawm cov tshuaj tiv thaiv electrochemical thiab vim kev ua haujlwm ntawm cov khoom siv.

Txoj Cai Ua Haujlwm

Lub hauv paus ntawm lub zog muab los ntawm substation yog cov khoom siv hluav taws xob tag nrho. Los ntawm lawv, qhov hluav taws xob yog nkag mus rau lub converting thiab distributing substation, uas yog feem ntau nyob ze. Kev ua haujlwm tau hais los saum toj no ntawm kev nce qhov hluav taws xob txhawm rau txhawm rau txo qis hauv kab yog nqa tawm vim qhov kev txiav txim ntawm cov kauj ruam-up transformer li. Nyob rau hauv lub neej yav tom ntej, ib kauj ruam-down transformer kuj ua tau raws li ib tug receiver ntawm hluav taws xob, uas optimizes lub voltage yam ntxwv rau qhov zoo tshaj plaws sawv daws yuav los ntawm qhov pom ntawm kev siv nyob rau hauv lub zos network. Txhawm rau ua cov haujlwm no kom ruaj khov, mast transformer substation yuav tsum tau ua kom txias tsis tu ncua. Feem ntau, cov tshuab cua txias yog cov khoom siv nrog cov khoom siv roj. Qhov no yog ib qho ntawm cov kab ke ua kom muaj kev ntseeg siab ntawm hom substations.

Nyob ntawm mast substations

Muaj ob txoj hauv kev rau kev ua raws li kev tsim qauv ntawm cov chaw ua haujlwm substations. Ib qho kev xaiv yooj yim dua yog qhov ua tiav transformer substation, uas muaj tus qauv A-zoo li sab nraud. Cov qauv zoo li no suav nrog cov txheej txheem disconnectors nrog lub tshuab tsav, cov khoom tso tawm, fuses thiab lub zog hloov hluav taws xob nrog cov khoom xa tawm.

Qhov kev xaiv thib ob yog qhov nyuaj, ua haujlwm ntau dua thiab ua haujlwm zoo li U-puab chaw nres tsheb. Thiab yog hais tias thawj ntau yam yog feem ntau ua tiav, ces nyob rau hauv cov ntaub ntawv no, installation yuav nqa tawm siv npaj-rau-sivthaiv kev teeb tsa. Txawm li cas los xij, qhov ua tiav transformer substation feem ntau yog siv rau hauv qhov kev teeb tsa no. Cov qauv ntawm cov txheej txheem no suav nrog cov txheej txheem tib yam, tab sis nrog qee qhov sib txawv. Tshwj xeeb, qhov chaw nres tsheb U-shaped kuj muaj qhov txwv tsis pub muaj hluav taws xob, thiab cov khoom xa tawm feem ntau yog sawv cev los ntawm cov khoom siv hluav taws xob tsawg

Yuav ua li cas yog ib tug ncej transformer substation?

Kev teeb tsa suav nrog ntau yam haujlwm, suav nrog kev xa khoom, kev ua haujlwm sib dhos thiab nrawm ntawm cov khoom txhawb nqa. Tom ntej no, lub installation txoj hauj lwm yog reconciled, tom qab uas cov blocks npaj tau ntim nrog cov khoom siv hluav taws xob. Kev sib txuas ncaj qha ntawm cov cuab yeej siv rau ib leeg tsuas yog ua tom qab qhov kawg hloov kho thiab hloov kho cov khoom siv. Feem ntau, ib lub mast transformer substation yog nruab nrog cov cuab yeej siv cov cuab yeej tshwj xeeb. Piv txwv li, lub hwj chim transformer tuaj yeem nqa mus rau kev txhawb nqa los ntawm lub tsheb crane. Tom qab ntawd lub thaiv yog tsau - ntawm kev txhawb nqa pob zeb, kev kho yog nqa tawm siv lub thav duab hlau, uas, nyob rau hauv lem, tuav ntawm kev txhawb nqa nrog hlau clamps.

Zaj lus

Pillar substations vim lawv tsim tau dav siv hauv ntau yam lag luam. Cov tuam txhab tsim cov qauv tshwj xeeb rau kev siv hauv kev ua liaj ua teb, txhim kho cov txheej txheem yooj yim ntawm kev siv thoob ntiaj teb, tsim cov qauv muaj zog ua tiav los pab cov kev xav tau ntawm kev lag luam.cov khoom, thiab lwm yam. Tab sis txawm hais tias tus tsim, mast-hom transformer substation tseem ntseeg siab txhim kho nyob rau hauv cov nqe lus ntawm technology. Cov neeg tsim khoom tsim cov khoom ntawm cov tiam tshiab, cov haujlwm uas twb tau ua raws li cov hauv paus ntsiab lus ntawm automation. Ntawm ib sab, qhov kev hloov pauv no cuam tshuam cov qauv thiab lawv cov kev tswj hwm, tab sis ntawm qhov tod tes, nws tso cai rau cov nqi hluav taws xob zoo thiab cov nqi nyiaj txiag rau kev saib xyuas, tsis hais txog kev nce kev ntseeg siab thiab kev nyab xeeb.
