Hluav taws xob hloov chaw nres tsheb

Qhov chaw nres tsheb hluav taws xob hloov hluav taws xob, tseem hu ua qhov chaw hloov hluav taws xob, yog ib qho tseem ceeb ntawm daim phiaj hluav taws xob hauv nroog thiab tuaj yeem nkag siab tias "chaw hloov chaw" lossis "chav xa khoom" ntawm hluav taws xob. Txawm hais tias nws tsis muaj qhov hloov pauv thiab tsis hloov qhov voltage, nws ua cov haujlwm tseem ceeb ntawm kev txais, faib thiab tswj cov dej ntws ntawm hluav taws xob.

Lub luag haujlwm tseem ceeb ntawm lub chaw nres tsheb switchgear yog kom mloog zoo thiab xa rov qab lub zog ntawm tib theem voltage los txhim kho qhov kev ntseeg siab, kev yoog raws thiab kev lag luam ntawm cov khoom siv hluav taws xob, qhov chaw nres tsheb switchgear yog qhov tseem ceeb ntawm cov ntse ntse hluav taws xob tam sim no.

 

 

Lub luag haujlwm tseem ceeb ntawm qhov chaw nres tsheb hluav taws xob hloov hluav taws xob yog raws li hauv qab no:

1. Kev sau thiab faib hluav taws xob hluav taws xob: Sau thiab faib ntau qhov siab - cov kab hluav taws xob (xws li 10kV lossis 20kV) los ntawm sab sauv - theem substation rau cov neeg siv nyob ib puag ncig lossis qis dua - cov chaw faib khoom.
2. Txhim khu kev ntseeg tau lub zog:
Ntau cov khoom siv hluav taws xob xa tuaj: Feem ntau, muaj ob lossis ntau lub zog xa hluav taws xob tuaj, tsim lub nplhaib network fais fab mov qauv. Thaum ib qho khoom siv fais fab tsis ua haujlwm, nws tuaj yeem hloov mus rau lub zog ib txwm muaj, ua tiav lub zog hluav taws xob yam tsis muaj kev cuam tshuam.
Isolating faults: Ceev nrooj disconnect tus faulty outgoline kab mus cais qhov txhaum point, kom ntseeg tau ib txwm fais fab mov rau lwm cov kab.
3. Kev saib xyuas thiab kev tiv thaiv: Nruab nrog cov khoom siv tiv thaiv relay thiab kev saib xyuas, tiag - lub sijhawm saib xyuas tam sim no, qhov hluav taws xob, thiab lwm yam tsis raug, rau kev txiav txim txhaum cai thiab rov kho lub zog.
4. Txo qhov siab ntawm substation tawm txoj hauv kev: Los ntawm kev tsim cov chaw faib khoom hauv cov chaw thauj khoom, siv cov kab siab -voltage, faib hluav taws xob rau cov neeg siv ntau dua, thiab txo qhov nro ntawm substation cov kab tawm.

 

 

Hluav taws xob hloov chaw nres tsheb feem ntau suav nrog cov hauv qab no:

1. Hloov cov txee (cov khoom siv tseem ceeb):

• AIS (Air Insulated Switchgear): Ib txwm hom, nrog lub ntim loj.
• GIS (Gas Insulated Switchgear): Siv SF6 thiab lwm yam roj cua rau rwb thaiv tsev, uas muaj cov qauv compact, me me hneev taw, muaj kev ntseeg siab.

2. Cov khoom siv hluav taws xob tseem ceeb:

• inlet- qhov hluav taws xob kab hloov pauv: Load keyboards lossis circuit breakers.
• Busbars: Cov khoom siv uas sau thiab faib hluav taws xob hluav taws xob.
• Transformers: suav nrog CT (Tam sim no Transformer) thiab PT (Voltage Transformer), siv rau kev ntsuas thiab kev tiv thaiv.
• Relay tiv thaiv cov cuab yeej: Saib xyuas cov xwm txheej txawv txav thiab teeb tsa cov lus qhia mus txawv tebchaws.
• Fuses: Tiv thaiv xob laim overvoltage los ntawm cov khoom puas.

3. Cov kev pab cuam:

• DC Operating Power Supply System: Muab lub zog rau kev tiv thaiv cov khoom siv thiab hloov ua haujlwm.
• SCADA (Kev Saib Xyuas Kev Tswj Xyuas thiab Kev Tshawb Fawb Cov Ntaub Ntawv): Ua tiav "kev ntsuas chaw taws teeb, teeb liab chaw taws teeb, tswj chaw taws teeb, thiab hloov chaw taws teeb" ua haujlwm.
• Environmental Control System: suav nrog teeb pom kev zoo, qhov cua, tiv thaiv hluav taws, thiab kev ruaj ntseg (kev tswj xyuas, kev soj ntsuam video).
