Dab tsi yog kev faib tawm ntawm switchgear?

Switchgear tuaj yeem muab faib ua ntau txoj hauv kev, feem ntau raws li qib voltage, daim ntawv thov, qauv, kev teeb tsa ib puag ncig, thiab kev ua haujlwm. Cov kev faib tawm sib txawv yog tsim rau cov xwm txheej sib txawv, thiab kev xaiv kom raug tuaj yeem txhim kho kev nyab xeeb thiab kev ua haujlwm ntawm lub zog.

 

1. Kev faib tawm raws li qib Voltage

Tsawg-voltage switchgear: Siv nyob rau hauv lub tshuab fais fab hauv qab 500V, feem ntau pom nyob rau hauv cov tsev, factories, thiab lwm yam kawg -cov neeg siv qhov chaw, xws li qauv GGD, GCK, GCS, thiab MNS.

Nruab nrab-voltage switchgear: Haum rau 3kV, 6kV, thiab 10kV systems, feem ntau yog siv nyob rau hauv industrial faib chav lossis substations, xws li KYN28-12 nruab nrab-voltage switchgear.

High-voltage switchgear: Siv nyob rau hauv 24kV, 35kV, thiab saum toj no systems, feem ntau pom nyob rau hauv loj substations thiab tshiab zog fais fab nroj tsuag.

 

2. Kev faib tawm los ntawm Daim Ntawv Thov

Cov kab khoom nkag: Tau txais hluav taws xob hluav taws xob los ntawm cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob sab saud; nws yog "qhov chaw nkag" ntawm tag nrho cov hluav taws xob faib hluav taws xob. Outgoing Line Cabinet: Faib hluav taws xob rau cov khoom siv hluav taws xob tshwj xeeb lossis cov thawv xa khoom hauv qab.

Bus Txuas Txee: Txuas thiab hloov pauv ntawm ntau qhov chaw busbar, txhim kho kev ntseeg tau ntawm lub zog.

Metering Txee: Muaj lub ntsuas hluav taws xob rau kev ntsuas hluav taws xob thiab kev them nqi.

Capacitor Compensation Cabinet (Compensation Cabinet): Txhim kho lub zog thiab txo cov kab poob los ntawm kev sib txuas cov capacitors nyob rau hauv parallel.

PT txee (Voltage Transformer Txee): Siv rau kev ntsuas hluav taws xob thiab kev tiv thaiv relay.

UPS / Emergency Power Supply Txee: Muab lub zog tsis muaj kev cuam tshuam lossis lub zog kub ceev rau cov khoom siv tseem ceeb.

 

3. Kev faib tawm los ntawm Cov Qauv Txheej Txheem

Tsau Cov Txiaj Ntsig: Xws li hom GGD, yooj yim hauv cov qauv thiab tus nqi qis, tab sis yuav tsum muaj kev sib txuas hluav taws xob rau kev saib xyuas; haum rau daim ntaub ntawv nrog ob peb circuits thiab ruaj khov loads.

Cov tub rau khoom- hom (rub- tawm) cov khoom xa tawm: xws li GCK, GCS, MNS, uas nruab cov kab hluav taws xob thiab lwm yam khoom hauv rub- tawm cov tub rau khoom, ua rau kev saib xyuas yooj yim thiab tsis cuam tshuam rau kev ua haujlwm ntawm lwm lub voj voog. Lawv tsim nyog rau cov xwm txheej nrog cov khoom hnyav hnyav thiab ntau lub voj voog.
