Transformer thiab substation: Cov pob txha ntawm lub zog niaj hnub
Cia peb ua tiag tiag- feem ntau ntawm peb tsis xav txog yuav ua li cas hluav taws xob nkag mus rau peb lub tsev kom txog thaum muaj qee yam tsis raug. Thiab thaum nws ua haujlwm (feem ntau hnub), nws yog qhov yooj yim los coj nws kom pom zoo. Tab sis tom qab qhov xwm txheej, muaj ntau yam khoom siv hluav taws xob ua kom lub zog xa khoom muaj kev nyab xeeb thiab ntseeg tau.
Ob qho laj thawj loj tshaj plaws niaj hnub siv hluav taws xob faib ua haujlwm yog lub transformer thiab substation.
(Nyem daim duab kom paub ntxiv.)
Transformer yog dab tsi?
A transformeryog ib qho khoom siv hluav taws xob uas hloov hluav taws xob ntawm cov hluav taws xob siv hluav taws xob induction. Qhov tseem ceeb uas nws ua yoghloov voltage theem.
Hauv txhua hnub, transformers pab hluav taws xob ua ob txoj haujlwm tseem ceeb:
Boost voltageyog li nws tuaj yeem taug kev mus ntev yam tsis tas siv zog ntau dhau
Tsawg voltageyog li lub zog muaj kev nyab xeeb thiab siv tau rau tsev, tsev kawm ntawv, tsev kho mob, kev lag luam, thiab chaw ua haujlwm
Yog tsis muaj kev hloov pauv, xa hluav taws xob mus ntev thiab xa nws mus rau cov neeg siv khoom yuav nyuaj dua (thiab hais ncaj, tsis tshua muaj txiaj ntsig).
Substation yog dab tsi?
A substationyog ib qho chaw nyob hauv daim phiaj hluav taws xob uas lub zog tau txaistswj, taug kev, thiab -feem ntau- khoua ntej nws txuas ntxiv mus rau ntu txuas ntxiv ntawm lub network.
Lub substation yog qhov uas hluav taws xob "tau txais kev tswj hwm." Hauv, feem ntau koj yuav pom tej yam xws li:
Circuit Court breakers thiab disconnect keyboards
Tiv thaiv relays
Busbars
Cov cuab yeej saib xyuas
Transformers (nyob ntawm seb lub substation tsim)
Substations tsis yog pab txav hluav taws xob xwb-lawv kuj pab tiv thaiv kab sib chaws thaum muaj ib yam dab tsi txawv txav.
Yuav ua li cas Transformer thiab Substation Systems ua haujlwm ua ke
Ntawm no yog qhov uas nws tau txais txiaj ntsig zoo nkauj: lub transformer thiab substation ua haujlwm zoo li pab pawg.

Ib qho yooj yim version ntawm yuav ua li cas hluav taws xob feem ntau ntws zoo li no:
Thaum txhua yam ua haujlwm tau zoo, daim phiaj ua haujlwm tau zoo thiab kev tawm tsam tsawg dua. Thaum ob qho tib si muaj teeb meem, koj tuaj yeem xaus nrog cov teeb meem hluav taws xob, kev ntxhov siab ntawm cov khoom siv, lossis kev cuam tshuam.
Hom Substations
Tsis yog txhua qhov chaw substation yog tsim los rau tib txoj haujlwm. Nyob ntawm seb qhov twg nws zaum hauv lub zog hluav taws xob thiab nws txhais tau li cas, koj yuav pom ntau hom:
Transmission Substations
Cov no yog tsim los txuas cov kab sib txuas thiab txav cov fais fab ntawm cov hluav taws xob siab heev.
Distribution Substations
Cov kauj ruam no xa hluav taws xob mus rau theem uas ua haujlwm rau kev xa khoom hauv zos - feem ntau ze rau cov zej zog thiab cov lag luam.
Industrial Substations
Cov chaw lag luam loj qee zaum xav tau lawv tus kheej substations los tswj cov khoom hnyav kom nyab xeeb thiab ua kom lub zog zoo tsis tu ncua.
Renewable Energy Substations
Nrog ntau lub hnub ci thiab cua tsim los hauv online, substations kuj pab koom ua ke lub zog tauj dua tshiab rau hauv daim phiaj uas twb muaj lawm.
Vim li cas Transformer thiab Substation Maintenance Matters tseem ceeb
Lub transformer thiab substation tsis yog "nruab nws thiab tsis nco qab nws" cov khoom siv. Lawv khiav mus ntev, tab sis lawv tseem hnav dhau lub sijhawm. Thaum tshav kub kub, noo noo, plua plav, cov khoom qub, thiab hluav taws xob muaj zog tuaj yeem ua rau muaj teeb meem yog tias tsis muaj dab tsi ua.
Kev kho yuav muaj xws li:
Test transformer roj thiab rwb thaiv tsev mob
Thermal soj ntsuam kom ntes overheating
Ntxuav cov insulators kom tsis txhob muaj teeb meem kev ua haujlwm
Tshawb xyuas kev tiv thaiv relays thiab hloov iav
Saib xyuas kev thauj khoom thiab kev ua haujlwm
Tshawb xyuas cov cua txias thiab cua tshuab
Yog tias kev saib xyuas tau hla, kev ua tsis tiav yuav tshwm sim ntau dua - thiab kev kho thaum muaj xwm txheej ceev yuav raug nqi ntau thiab cuam tshuam. Kev tiv thaiv kev tiv thaiv ua rau lub cev ruaj khov, thiab ua siab ncaj, nws pheej yig dua li tos kom tawg.
Kev nyab xeeb nyob ib puag ncig Transformer thiab substation chaw
High - qhov chaw hluav taws xob yog kev lag luam loj. Transformer thiab
substation chaw muaj hluav taws xob txaus ntshai, thiab txawm tias me me yuam kev tuaj yeem ua rau raug mob hnyav lossis hnyav dua.
Tias yog vim li cas cov cheeb tsam no feem ntau tiv thaiv los ntawm:
Kev ruaj ntseg laj kab thiab txwv kev nkag
Cov cim ceeb toom
Grounding systems
Cov txheej txheem kev nyab xeeb thiab kev cob qhia neeg ua haujlwm tshwj xeeb
Kev tshuaj xyuas cov tshuab txhawm rau txheeb xyuas cov teeb meem ntxov
Rau txhua tus neeg, txoj cai zoo tshaj plaws yog qhov yooj yim:tsis txhob nkag los yog cuam tshuam nrog cov chaw hluav taws xobtshwj tsis yog tias koj tau tso cai thiab raug cob qhia.
Kev xav zaum kawg
Lub transformer thiab substation yog lub hauv paus ntawm yuav ua li cas hluav taws xob txav los ntawm cov fais fab nroj tsuag rau cov neeg siv niaj hnub. Transformers ua qhov hluav taws xob ua haujlwm ntev - kis tau tus mob thiab kev nyab xeeb kawg - siv, thaum lub chaw nres tsheb tswj kev faib khoom thiab tiv thaiv kab sib chaws.
Yog li yog- hluav taws xob tej zaum yuav zoo li tsis muaj zog ntawm koj qhov kawg, tab sis tom qab qhov xwm txheej, lub tshuab hluav taws xob thiab lub tshuab hluav taws xob no ua haujlwm tsis nres kom txhua yam khiav.
