I. Substation: Lub "Transformer" ntawm lub Hwj Chim

Core txhais

Ib qhov chaw hloov hluav taws xob, nws yog qhov tseem ceeb tshaj plaws hloov dua siab tshiab ntawm lub zog hluav taws xob. Cov hluav taws xob tsim los ntawm cov chaw tsim hluav taws xob (feem ntau tsis tshaj 1-2 kV) tsis tuaj yeem xa mus rau qhov ntev ncaj qha. Substations nce mus txog kaum lossis ntau pua kilovolts rau kev sib kis, tom qab ntawd nqis mus rau qib siv tau ntawm qhov chaw.

Ntsiab nta

● Yuav tsum muaj transformers: Cov khoom siv tseem ceeb rau kev hloov hluav taws xob.

● Cov nplai loj: npog thaj tsam ntawm ntau pua txog kaum txhiab square meters, nyob ntawm qhov voltage thiab muaj peev xwm.

● Ua tiav kev ua haujlwm: suav nrog tag nrho cov chaw xws li hloov khoom siv, cov cuab yeej tiv thaiv, thiab cov tshuab tswj.

Lub luag haujlwm tseem ceeb

1.Voltage Conversion: High-voltage transmission → Nruab nrab/Low-voltage distribution.

3.System Control: Kho qhov hluav taws xob, tswj lub zog khiav kev taw qhia, thiab tiv thaiv kev ruaj ntseg.

Qhov yuav tsum tau muaj zaum (Key Standards)

● Kaw rau cov chaw thauj khoom: Txo cov kab poob.

● Kev cais kev nyab xeeb: Tsis txhob muaj cov nplaim hluav taws kub, tawg, thiab muaj neeg coob coob.

● Kev hloov pauv ib puag ncig: txiav txim siab tshwj xeeb cov cai xws li dej nyab, seismic, thiab kev tiv thaiv kab tsuag.

● Upwind qhov chaw: Zoo dua nyob rau sab saud hauv cov chaw lag luam.

Simple Analogy: Ib lub chaw nres tsheb zoo li "ntev- chaw nres tsheb npav deb" rau hluav taws xob. Lub zog hluav taws xob yuav tsum "hloov" ntawm no ua ntej tawm mus (qib-nce) thiab tom qab tuaj txog (qib- nqis).

 

II. Fais fab Distribution Station: Tshwj xeeb Voltage Conversion Points

Kev sib raug zoo nrog Substations

Qhov tseem ceeb, nws yog ib qho me me - scale substation lossis substation rau lub hom phiaj tshwj xeeb. Hauv kev lag luam fais fab, cov ntsiab lus qee zaum siv sib hloov, tab sis "Power Distribution Station" feem ntau hais txog cov haujlwm tshwj xeeb.

Kev faib tawm thiab kev siv

● Fais fab Substation: Voltage conversion point nyob rau hauv cov pa hluav taws xob systems.

●Traction Substation: Rau cov hluav taws xob railways, hloov peb -theem high voltage mus rau ob-theem 27.5 kV mov.

Traction substations yog nruab nrog Sectioning Posts:

●Qhov chaw: nruab nrab ntawm ob lub chaw nres tsheb sib tw.

●Function: Sectional power supply, txhaum cais, txwv tsis pub muaj.

●Effect: tuaj yeem ua rau thaj tsam cuam tshuam ib nrab thaum muaj xwm txheej.

 

III. Chav Faib Fais Fab: Qhov "Lub Xeem -Mile Distribution Station"

Core txhais

Ib lub chaw fais fab uas tsuas yog faib tsis tau hloov hluav taws xob. Lub teb chaws cov qauv qhia meej meej: Chav Faib Faib Fais Fab muaj tsuas yog siab - cov khoom siv hluav taws xob faib hluav taws xob, tsis muaj qhov hloov pauv loj ntawm cov npav.

Voltage Ntau

Feem ntau qis dua 35 kV.

Feem ntau 10 kV faib tshuab.

Cov khoom sib xyaw

● Cov khoom siv tiv thaiv thiab ntsuas.

●(Tej zaum yuav suav nrog cov khoom siv hluav taws xob tsawg-).

Qhov tseem ceeb Distinction: Public vs. Dedicated

Hom	Tswj los ntawm	Cov khoom siv fais fab rau	Yam ntxwv
Public Power Distribution Room	Power Supply Bureau	Hluav taws xob nyob	pej xeem tswv cuab, centralized tswj.
Dedicated Power Distribution Room	Owner/Property Management	Cov chaw pej xeem thauj khoom (elevators, twj tso kua dej, tiv thaiv hluav taws, thiab lwm yam)	Tus tswv- tswj hwm, tshwj xeeb thauj khoom.

Tiag -Lub Ntiaj Teb Scenario: Ib lub tsev loj loj feem ntau muaj ib chav faib rau pej xeem (rau tsev neeg) thiab ob peb lub siab (rau cov chaw pej xeem).

 

IV. Hloov Chaw Nres Tsheb: Qhov "Distribution Hub" rau Fais Fab

Unique Function

Kev faib tawm yam tsis muaj qhov hloov pauv voltage- qhov no yog qhov sib txawv ntawm lub chaw nres tsheb. Ib lub chaw hloov pauv tau txais ib qho khoom siv hluav taws xob thiab muab faib rau hauv ntau yam khoom noj ntawm tib theem voltage ntawm ntau lub tshuab hloov khoom siv.

Kev ua haujlwm hom

Substation → Ib qho 10kV pub → [Switching chaw nres tsheb] → Ntau 10kV pub → Ntau tus neeg siv

(Voltage tseem tsis hloov tag nrho).

Tus nqi tseem ceeb

1. Txhim kho kev ntseeg tau: Sectionalized mov txwv kev cuam tshuam rau cheeb tsam hauv cheeb tsam thaum ua txhaum.

● Cov chaw thauj mus los loj: Ntau -zone fais fab mov rau chaw nres tsheb, tshav dav hlau.

● Cov cheeb tsam hauv nroog: Kev faib hluav taws xob rau siab - qhov chaw thauj khoom ceev.

 

V. Compact Substation (Box-Type Transformer): Qhov Kev Sib Txuas "Portable Power Station"

Tsim tshiab

Kev koom ua ke peb qhov chaw ua haujlwm tseem ceeb ntawm lub chaw ua haujlwm ib txwm muaj rau hauv ib qho chaw txav tau yooj yim:

1.High-Voltage Compartment: Cov kab nkag, cov khoom siv tiv thaiv.

2.Transformer Compartment: Core rau voltage hloov dua siab tshiab.

3.Low-Voltage Compartment: Cov kab tawm, cov khoom ntsuas ntsuas.

Qhov Zoo Tshaj Plaws

● Cov hneev taw me me: Tsuas yog 1/5 txog 1/10 qhov loj ntawm lub chaw nres tsheb ib txwm muaj.

● Kev xa tawm sai: Lub Hoobkas-prefabricated, ceev ntawm -site installation.

● Ib puag ncig tus phooj ywg: Tsis tshua muaj suab nrov, zoo nkauj txaus nyiam, hloov mus rau ntau qhov chaw.

Daim ntawv thov Scenario

● Lub hwj chim ib ntus: Cov chaw tsim kho, chaw ua yeeb yam.

●Space- thaj chaw txwv: Kev kho dua tshiab ntawm cov zej zog qub, thaj chaw hauv nroog.

● Muaj peev xwm nthuav dav: Kev siv hluav taws xob thaum muaj xwm txheej ceev rau thaj chaw uas muaj kev thauj khoom sai sai.

 

Jinneng12/0.4kV Prefabricated Secondary Distribution Substationyog ib qho ua tiav, ua ntej- sib dhos, sab nraum zoov- teeb tsa hluav taws xob faib khoom uas hloov 12kV nruab nrab- hluav taws xob hluav taws xob mus rau 400V qis- hluav taws xob hluav taws xob thiab xa mus rau cov neeg siv khoom kawg. Nws koom ua ke tag nrho cov haujlwm ntawm ib qho chaw ua haujlwm ib txwm ua rau hauv ib lossis ob peb lub thawv thauj khoom hlau.

VI. Yuav Ua Li Cas Ceev Qhia Lawv Sib nrug? Phau Ntawv Qhia Txog Tswv Yim
