Yuav Ua Li Cas Xaiv Ib Lub Txiaj Ntsig Hauv Nruab Nrab Thiab Lub Siab -voltage Switchgear

Qhov kev xaiv ntawm lub hauv paus tswj txee thiab siab -voltage switchgear feem ntau yog nyob ntawm daim ntawv thov, qib voltage, thiab tswj kev ua haujlwm. Ob hom no ua lub luag haujlwm sib txawv hauv lub zog hluav taws xob thiab feem ntau tsis hloov pauv ncaj qha; es, lawv yog siv nyob rau hauv ua ke raws li qhov system qauv. Hauv qab no, kuv yuav muab cov ncauj lus kom ntxaws los ntawm ntau qhov loj me thiab muab cov lus qhia xaiv.

Core Differences: Lub luag haujlwm sib txawv kiag li

1. Siab -Voltage Switchgear

Lub luag haujlwm tseem ceeb: Chav ua haujlwm, "cov leeg" thiab "kev nyab xeeb hloov" ntawm lub zog hluav taws xob.

Core Functions:

1) Kev sib txuas, nqa, thiab txiav tawm qhov qub / txhaum tam sim no: ncaj qha ua haujlwm rau / tawm ntawm siab - cov kab hluav taws xob.

2) Voltage Level: Feem ntau yog hais txog kev faib hluav taws xob theem ntawm 3.6kV - 40.5kV (qhov nruab nrab voltage) thiab saum toj no . 4. Daim Ntawv Thov: Substation cov kab nkag, kab tawm, busbar sectionalizing, transformer tiv thaiv, thiab lwm yam.

2. Central Control Txee

1) Lub luag haujlwm tseem ceeb: Kev hais kom ua thiab kev saib xyuas qhov chaw, "lub hlwb" thiab "ntsuab chaw" ntawm lub zog hluav taws xob.

2) Voltage Level: Internally, nws feem ntau muaj tsawg-voltage (piv txwv li, 220V AC / 24V DC) tswj cov khoom siv hluav taws xob thiab hluav taws xob hluav taws xob.

3) Daim Ntawv Thov Scenario: Cov chav tswj, chaw xa khoom, ua tus saib xyuas tseem ceeb ntawm tag nrho cov chaw tsim hluav taws xob thiab lub Hoobkas hluav taws xob faib hluav taws xob.

Kev txiav txim siab-Ua Logic: Tsis yog "OR," tab sis "Yuav ua li cas rau Configure"

Hauv cov haujlwm tiag tiag, cov kev txiav txim siab uas koj ntsib feem ntau yog:

Scenario 1: Muab kev tiv thaiv thiab tswj rau ib qho siab -voltage circuit lossis me switchgear

· Qhov kev xaiv raug: High-voltage switchgear.

· Yog vim li cas: Nws integrates thawj switching khoom thiab lwm yam kev tiv thaiv / tswj units, nws tus kheej ua kom tiav cov kev tiv thaiv, ntsuas, thiab lub zos ua hauj lwm ntawm lub Circuit Court. Hauv qhov no, kev tswj hwm kev ua haujlwm yog decentralized.

Scenario 2: Kev tsim kho lossis txhim kho lub chaw nres tsheb ua tiav / chaw nres tsheb fais fab uas xav tau kev tswj hwm hauv nruab nrab

· Qhov kev xaiv raug: Kev sib xyaw ua ke ntawm "siab-voltage switchgear" + "central control txee/system".

· Yog vim li cas:

1. Lub siab -voltage switchgear yog lub luag haujlwm rau ntawm -chaw fais fab chaw faib khoom thiab kev tiv thaiv kev nyab xeeb (txheej txheej).

2. Lub hauv paus tswj txee yog lub luag haujlwm rau kev sib sau cov ntaub ntawv los ntawm txhua qhov hloov pauv rau kev saib xyuas hauv nruab nrab thiab kev tswj chaw taws teeb (txheej txheej tswj).

· Qhov no yog tus qauv architecture ntawm niaj hnub ntse substations, ua tiav "decentralized tswj, centralized tswj".

Scenario 3: Tam sim no siab -voltage switchgear, tab sis yuav tsum tau hloov kho hauv qib automation

· Qhov kev xaiv raug: Ntxiv lossis txhim kho lub hauv paus tswj txee (system).

• Yog vim li cas: Los ntawm kev ntxiv ib chav tswj kev sib txuas lus thiab tsim kom muaj lub network saib xyuas, cov ntaub ntawv los ntawm cov hloov pauv uas tau tawg yav dhau los tuaj yeem ua ke kom ua tiav kev ua haujlwm tsis tu ncua lossis ntse thiab kev saib xyuas.

Cov ntsiab lus thiab cov lus pom zoo

1. Qhia meej txog qib uas xav tau:

* Yog tias koj xav tau cov cuab yeej uas ncaj qha tswj lub hwj chim qhib / tawm thiab muab kev tiv thaiv, koj yuav tsum yuav siab -voltage switchgear.

* Yog tias koj xav tau lub hub hauv nruab nrab uas tuaj yeem saib xyuas thiab tswj ntau lub tshuab hloov pauv thiab lwm yam khoom siv, koj yuav tsum npaj thiab tsim lub hauv paus tswj kev tswj hwm thiab muab nws nrog cov khoom siv hauv nruab nrab (muaj kev sib txuas lus, saib xyuas tus tswv, thiab lwm yam).

2. Ua raws li Tus Qauv Tsim: Rau cov haujlwm tshiab, nws raug pom zoo kom sab laj nrog lub koom haum tsim hluav taws xob tsim nyog lossis tus neeg koom ua ke. Lawv yuav tsim ib qho kev daws teeb meem nrog rau thawj theem siab -voltage switchgear thiab ib qho kev soj ntsuam thib ob (chaw tswj hwm hauv nruab nrab) raws li cov phiaj xwm muab hluav taws xob, qib automation, thiab pob nyiaj siv. Qhov ob yog complementary thiab indispensable.

3. Hais txog Kev Sib Raug Zoo: Yog tias xaiv cov kev daws teeb meem sib xyaw, nws yog ib qho tseem ceeb kom ntseeg tau tias cov khoom siv tiv thaiv ntse ntawm lub siab -voltage switchgear tuaj yeem sib txuas lus zoo nrog kev saib xyuas ntawm lub hauv paus tswj txee (xws li, txhawb cov txheej txheem kev cai xws li Modbus thiab IEC 61850). Qhov no yog lub hauv paus rau kev ua tiav cov haujlwm automation. Yooj yim tso: siab -voltage switchgear yog "tus neeg ua haujlwm," thaum lub hauv paus tswj txee yog "tus thawj coj." Lub tshuab hluav taws xob ua tiav tag nrho xav tau cov neeg ua haujlwm thiab cov tswj hwm. Thov txiav txim siab seb puas yuav tau txais cov haujlwm ua tiav lossis tsim lub chaw hais kom ua raws li koj lub luag haujlwm hauv tag nrho cov txheej txheem.
