Medium Voltage Switchgear yog dab tsi?

Nruab nrab voltage switchgearyog tag nrho cov txheej txheem txee fais fab. Nws tswj cov hluav taws xob hluav taws xob nrog hluav taws xob xws li 1kV txog 52kV, nrog rau kev ntsuas ntawm 3.6kV, 12kV, 24kV thiab 40.5kV. Koj tuaj yeem pom cov khoom siv no hauv substations, cov chaw tsim khoom loj thiab cov chaw siv hluav taws xob txuas ntxiv dua tshiab.

Koj tuaj yeem pom cov npe sib txawv ntawm cov ntaub ntawv ua haujlwm.MV hloovfeem ntau siv interchangeably nrognruab nrab voltage switchgear. Nws txuas cov khoom siv hluav taws xob tseem ceeb thiab cov khoom siv hluav taws xob kawg, cia cov neeg ua haujlwm yooj yim tswj lub zog txaus rau tag nrho lub zog.

Core Functions ntawm Nruab Nrab Voltage Switchgear

Cov cuab yeej no muaj peb txoj haujlwm tseem ceeb rau txhua qhov chaw siv hluav taws xob.

Ua ntej, nws muaj kev nyab xeeb hloov hluav taws xob circuits rau thiab tawm rau kev ua haujlwm txhua hnub.

Qhov thib ob, thaum overloads los yog luv luv Circuit Court tshwm sim, nws sai sai txiav tawm lub faulty Circuit Court. Qhov no tiv thaiv cables thiab lwm yam khoom siv hluav taws xob los ntawm kev puas tsuaj.

Thib peb, nws tsim kom muaj kev nyab xeeb lub zog cais cov ntsiab lus. Cov neeg ua haujlwm tuaj yeem txiav tawm hluav taws xob tau yooj yim los kuaj xyuas thiab kho, nrog kev pheej hmoo tsawg dua ntawm hluav taws xob poob.

Qhov yooj yim hais, peb tsis tuaj yeem khiav nyab xeebnruab nrab -voltagecov tshuab hluav taws xob rau cov chaw nyob, cov chaw tsim khoom thiab cov chaw hnub ci loj uas tsis muaj cov khoom siv tseem ceeb no.

Cov Cheebtsam tseem ceeb ntawm Medium Voltage Switchgear

Txhua lub txee ua tiav yog tsim los ntawm ntau qhov chaw ua haujlwm tseem ceeb uas ua haujlwm ua ke. Circuit Court breakers yog lub ntsiab hloov khoom siv los qhib lossis kaw lub zog ntws. Busbars faib hluav taws xob los ntawm cov khoom tseem ceeb rau cov khoom noj sib txawv. Cov cuab yeej hloov pauv (CT / VT) pub ntsuas thiab tiv thaiv cov cim, thiab kev tiv thaiv relays mus rau qhov tawg thaum kuaj pom qhov txhaum.

Earthing keyboards tshem tawm cov nqi seem kom cov neeg ua haujlwm tuaj yeem ua haujlwm tau zoo. Tam sim no - txwv tsis pub fuses ntxiv kev tiv thaiv kev phom sij tshaj - cov xwm txheej tam sim no, thiab cov kab hluav taws xob tshwj xeeb khaws tag nrho cov xaim kom zoo. Tag nrho cov khoom no haum rau hauv ib lub txee ruaj khov kom xa tau ruaj khov, tswj fais fab faib.

Hom Lub Npe Nruab Nrab Voltage Switchgear: AIS vs GIS vs Hlau -Clad

Muaj peb hom homnruab nrab voltage switchgearsiv nyob rau hauv lub ntiaj teb no hwj chim tej yaam num, thiab txhua tus haum rau qhov chaw sib txawv.

AIS (air{0}}insulated) units siv cua tsis tu ncua rau rwb thaiv tsev. Lawv raug nqi tsawg dua los yuav, tab sis lawv xav tau ntau qhov chaw teeb tsa. Lawv ua haujlwm zoo tshaj plaws hauv qhov chaw qhuav thiab huv.

GIS (gas{0}}insulated) units kaw tag nrho cov tseem ceeb nyob rau hauv ib lub chamber hlau nrog insulating roj. Lawv siv qhov chaw tsawg dua thiab ua haujlwm tau zoo rau cov chaw ntug dej hiav txwv, plua plav, lossis qhov chaw hauv av.

Hlau-clad switchgear siv cov khoom hlau barriers cais tag nrho cov tseem ceeb nyob rau hauv lub sab hauv compartments. Nws muab kev nyab xeeb ua tau zoo dua, yog li nws tau dav siv rau hnyav-cov haujlwm ua haujlwm substations.

Txhua hom muaj nws tus kheej zoo thiab drawbacks. Koj yuav tsum ua tib zoo sib piv lawv ua ntej xaiv cov cuab yeej zoo rau koj qhov project.

Yuav Ua Li Cas Xaiv Txoj Cai Nruab Nrab Voltage Switchgear rau Koj Qhov Haujlwm

Thaum koj xaiv koj, pib los ntawm kev txheeb xyuas koj qhov chaw teeb tsa muaj, thaj chaw hauv cheeb tsam, tag nrho lub zog thauj khoom, kev saib xyuas zaus, thiab tag nrho cov phiaj xwm phiaj xwm. Yog tias koj muaj chav tsev qhuav qhuav thiab xav kom tus nqi qis, AIS cov cuab yeej yuav ua tau raws li qhov xav tau ntawm qhov project. Rau qhov chaw kaw ntom nti lossis chaw ntug hiav txwv nrog cov ntsev ntsev hnyav, mus nrog GIS-style units. Xaiv cov hlau-cov qauv clad rau cov chaw lag luam substations uas yuav tsum muaj kev nyab xeeb nruj thiab lub zog loj. Nco ntsoov xav txog ntau npaum li cas koj cov neeg ua haujlwm yuav ua rau ntawm -kev kuaj xyuas thiab kho qhov chaw ua ntej xauv koj qhov kev txiav txim zaum kawg.

Cov ntsiab lus

Hauv luv luv, xaiv koj lub switchgear raws li koj qhov chaw tiag tiag, qhov chaw muaj thiab kev xav tau kev nyab xeeb, es tsis txhob xaiv cov khoom siv siab tshaj - kawg nkaus.

Yog tias koj tsis paub tseeb tias qhov twg switchgear haum rau koj chav tsev fais fab, lub zog thauj khoom thiab pob nyiaj siv, tsuas yog xa peb cov lus qhia txog qhov project. LVMA cov kws tshaj lij hluav taws xob engineers yuav muab tswv yim rau koj xaiv cov tswv yim thiab cov khoom siv ua tiav.
