Thaum tib neeg tham txog hluav taws xob faib, switchboard vs switchgear tuaj ntau heev. Lawv tuaj yeem ua suab zoo sib xws, thiab yog- muaj qee qhov sib tshooj ntawm lawvob leegua. Tab sis nyob rau hauv transformer setups, lawv ua si zoo nkauj txawv luag hauj lwm. Thiab paub qhov sib txawv tseem ceeb heev rau kev nyab xeeb, kev ntseeg siab, thiab hnub- mus rau - hnub ua haujlwm hauv cov chaw xws li cov chaw lag luam, cov tsev lag luam, thiab cov khoom siv hluav taws xob.
Cia peb ua kom yooj yim thiab siv tau.
Switchboard yog dab tsi?
Xav txog ibswitchboardraws li "main distribution hub" uas xa hluav taws xob tawm mus rau ntau lub voj voog.
Nws feem ntau tau txais hluav taws xob los ntawm lub tshuab hloov hluav taws xob (lossis lwm qhov chaw hluav taws xob tuaj) thiab tom qab ntawd muab faib rau cov ceg me me. Hauv lwm lo lus, nws yog qhov koj siv lub zog qhov twg nws yuav tsum mus - yam tsis tau ua kom ntxhov.
Feem ntau koj yuav pom switchboards hauv:
cov tsev lag luam
factories thiab cov chaw loj
txhua qhov chaw uas lub hwj chim yuav tsum tau muab faib ua ntau yam circuits
Hauv transformer-txog daim ntawv thov, switchboards feem ntau siv rau ntawmlow-voltage sab. Thaum lub transformer nce qhov voltage mus rau qib uas siv tau, lub switchboard faib lub hwj chim thoob plaws qhov chaw.
Switchboards kuj nrov vim tias lawv yog:
yooj yim dua rau kev saib xyuas
hloov tau rau expansion
feem ntau tus nqi ntau dua -zoo rau qis- mus rau nruab nrab-voltage xav tau
Uas tau hais tias, lub tshuab hluav taws xob feem ntau tsis yog tsim los daws qhov txhaum loj tshaj plaws -cov xwm txheej tam sim no lossis cov haujlwm tiv thaiv qib siab. Thaum koj xav tau qib kev tiv thaiv, koj saib mus rauswitchgear.
Switchgear yog dab tsi?
Switchgearyog qhov tseem ceeb tshaj, hnyav - txoj haujlwm xaiv. Nws tsis yog tsuas yog faib lub zog xwb- nws tau tsim lostiv thaivlub system thaum ib yam dab tsi mus tsis ncaj ncees lawm.
Qhov twg lub switchboard pab kis tau lub zog nyob ib ncig ntawm, switchgear yog tsom rau kev tswj thiab cais cov khoom thaum lub sij hawm ua txhaum xws li:
luv circuits
teeb meem overload
rwb thaiv tsev tsis ua hauj lwm
Nyob rau hauv transformer substations, switchgear feem ntau txuas rau ntawm lubsiab -voltage sab. Nws txoj haujlwm tseem ceeb yog tswj, txiav tawm, thiab tiv thaiv lub tshuab hloov pauv thiab cov khoom siv hluav taws xob nyob ib puag ncig nws.
Lub switchgear los ua ke tuaj yeem muaj xws li:
Circuit Court breakers
tiv thaiv relays
disconnect cov keyboards
fuses
tswj vaj huam sib luag
Nov yog lub ntsiab lus tseem ceeb:switchgear yog engineered los cuam tshuam txaus ntshai txhaum tam sim no yam xyuam xim.Nyob rau hauv siab -ib puag ncig fais fab, qhov muaj peev xwm yog qhov tseem ceeb-vim tias ib qho hluav taws xob loj tuaj yeem ua rau lub tshuab hluav taws xob puas, ua rau hluav taws xob, lossis ua rau muaj hluav taws kub.
Nyob rau hauv tas li ntawd, niaj hnub switchgear feem ntau tuaj nrog saib xyuas thiab automation nta. Cov neeg khiav dej num tuaj yeem taug qab cov xwm txheej hauv lub cev, tshawb xyuas cov khoom tsis raug cai, thiab cais cov teeb meem thaum ntxov -tshwj xeeb yog pab tau rau hauv kev lag luam thiab kev siv hluav taws xob qhov chaw poob qis (thiab tsis muaj leej twg xav tsis thoob).
Switchboard vs Switchgear: Qhov txawv ntawm qhov tseem ceeb
Yog li, thaum koj sib piv switchboard vs switchgear, qhov sib txawv loj tshaj yog kev tiv thaiv qib thiab yuav ua li cas / qhov twg lawv siv nyob rau hauv lub system.
A switchboardfeem ntau faib hwj chim.
Switchgearfaib lub zog ib yam nkaus, tab sis kev tiv thaiv thiab kev cuam tshuam tsis raug yog nws qhov tseem ceeb.
Qee qhov kev sib txawv ceev ceev:
Switchboards feem ntau yog siv rau hauvtsawg-voltagedaim ntawv thov.
Switchgear yog siv nyob rau hauvnruab nrab - thiab siab -voltagetshuab.
Switchgear handlessiab dua kev tiv thaivkev xav tau.
Switchboards feem ntau yogyooj yim dua thiab pheej yig dua.
Switchgear yog tsim rautseem ceeb infrastructurethiab tougher hluav taws xob tej yam kev mob.
Qhov twg yog qhov zoo dua rau kev siv Transformer?
Nov yog cov lus teb ncaj ncees: tsis muaj ib qho kev xaiv "zoo dua" uas haum rau txhua qhov xwm txheej.
Rau cov tsev lag luam me me uas xav tau kev faib khoom ib txwm muaj, aswitchboardtej zaum yuav txaus. Tab sis nyob rau hauv substations, loj industrial chaw, renewable zog nroj tsuag, thiab utility grids -qhov twg hluav taws xob muaj kev pheej hmoo siab dua -switchgearua qhov tseem ceeb.
Thiab ncaj ncees, nyob rau hauv ntau qhov zoo -tsim transformer systems, koj tsis xaiv ib los yog lwm yam - koj siv ob qho tib si.

Kab hauv qab
Thaum kawg ntawm hnub, switchboard vs switchgear tsis yog hais txog ib qho hloov lwm tus. Nws yog hais txog kev siv cov cuab yeej tsim nyog rau txoj haujlwm zoo- yog li lub kaw lus nyob nyab xeeb, txhim kho, thiab txhim khu kev qha. Thiab qhov ntawd yog qhov niaj hnub fais fab infrastructure xav tau.
