Lub hauv paus ntawm Pad-Mounted Transformers: Kev Ntsuas ntawm Plaub -Txoj Haujlwm Loadbreak Hloov
Hauv kev tsim qauv ntawm lub ncoo-mounted transformers, plaub- txoj hauj lwm loadbreak hloov (LBS) yog lub hauv paus tseem ceeb uas txiav txim siab txog kev siv hluav taws xob thiab kev nyab xeeb ntawm kev ua haujlwm. Nws tsis yog ib qho yooj yim ntawm -tawm lub cuab yeej tab sis "chaw hais kom ua" rau kev ua tiav lub voj- pub kev faib tawm, dual- qhov hloov pauv, thiab kev cais tawm txhaum. Kab lus no muab ib qho kev soj ntsuam nyob rau hauv - qhov tob ntawm kev tshawb nrhiav kev tshawb fawb, kev xaiv cov qauv, thiab cov txiaj ntsig zoo ntawm cov khoom tseem ceeb hauv kev faib khoom.
1. Puas yog "Four-Txoj Haujlwm" txhais li cas? - Ntau tshaj On / Off, Nws yog Hais Txog Logic
Qhov kev hloov no feem ntau yog teeb tsa ntawm qhov siab -voltage sab ntawm ncoo mounted transformers. Nws tus nqi tseem ceeb nyob hauv kev ua tiav plaub lub xeev sib txawv los ntawm ib qho kev sib hloov. Cov plaub lub xeev no tsis yog kev npaj random tab sis yog tsim los raws li cov cai tshwj xeeb ntawm kab sib chaws topology:
Terminal Txoj Haujlwm (Kab A ON, Kab B OFF):Lub transformer yog muab los ntawm thawj qhov chaw A, nrog B raws li thaub qab los yog txiav.
Terminal Txoj Haujlwm (Kab A OFF, Kab B ON):Lub transformer yog pauv mus rau qhov chaw thaub qab B.
Loop Position (A ON, B ON):Ob qhov chaw txuas nrog, ua kom lub voj voog - pub kev ua haujlwm - xyuas kom cov khoom siv txuas ntxiv txawm tias thaum tu ntawm ib kab.
Qhib Txoj Haujlwm (A OFF, B OFF):Lub transformer yog tag nrho cais tawm ntawm kab sib chaws, ua kom muaj kev ruaj ntseg.
Qhov kev teeb tsa no ua tau raws li qhov xav tau hloov pauv ntawm cov ncoo mounted transformers hauv voj - pub, dual - qhov chaw, lossis cov khoom siv davhlau ya nyob twg. Tsis zoo li Circuit Court breakers, lub loadbreak hloov tshwj xeeb yog tsim los cuam tshuam ib txwm load tam sim no thiab overload tam sim no (feem ntau nyob rau hauv 630A) tab sis tsis yog los cuam tshuam luv luv -circuit fault tam sim no- ib txoj hauj lwm delegated rau series - txuas backup fuse.
2. Blade Selection Logic: Lub Cev Cwj Pwm Qhia Txog Kev Nyab Xeeb Kev Nyab Xeeb
Nyob ntawm daim ntawv thov scenario, manufacturers muab ntau yam hniav configurations. Kev xaiv tsis raug tuaj yeem tsis tsuas cuam tshuam kev ua haujlwm xwb tab sis kuj ua rau muaj kev phom sij txaus ntshai- qhov xwm txheej kaw. Hauv qab no yog ib qho kev sib piv ntawm ob hom tseem ceeb:
A. Selector Blade (Code D/R/L)
Daim Ntawv Thov: Dual -qhov chaw hloov tsheb (yuav tsum muaj kev cais tawm ntawm lub cev)
Qhov kev tsim no siv ib qho - ncej, ib zaug - pov logic. Txhua qhov kev hloov pauv ntawm ib qhov chaw mus rau lwm qhov yuav tsum dhau los ntawm qhov tseeb "Qhib" txoj hauj lwm (hardwired "Rov Ua Ntej").
Qhov no lub cev mechanism structurally tshem tawm qhov muaj peev xwm ntawm unintended source paralleling. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov chaw zov me nyuam lossis cov xwm txheej nrog cov txheej txheem nruj synchronization, tiv thaiv cov circulating tam sim no loj heev los ntawm asynchronous source paralleling.
B. V-Blade (Code V)
Daim Ntawv Thov: Hauv Nroog Loop Distribution Networks (yuav tsum tau muab cov khoom tsis cuam tshuam)
V-Hloov tsim tso cai rau kev sib tshooj luv luv ntawm ob qhov chaw ("Ua Ua Ntej So"), ua tiav kev thauj khoom thauj yam tsis muaj kev cuam tshuam thaum lub sijhawm hloov pauv.
Ceeb Toom: Qhov kev ua haujlwm no nyob ntawm ob qhov chaw tau ua tiav hauv theem, zaus, thiab qhov hluav taws xob. Txwv tsis pub, qhov kev sib txuas luv luv yuav ua tau zoo yog qhov luv luv -circuit tshwm sim.
3. Engineering Advantages of Oil-Immersed Design
Yog vim li cas lub loadbreak hloov nyob rau hauv ncoo mounted transformers feem ntau cov roj -immersed? Qhov kev tsim no tso qhov hloov pauv ncaj qha rau hauv lub tank transformer, siv cov roj transformer ua ob qho tib si rwb thaiv tsev thiab arc -quenching nruab nrab. Qhov kev sib xyaw ua ke no muaj qhov zoo tseem ceeb:
Compact Footprint: Tshem tawm qhov xav tau ntawm cov pa sib cais-cov khoom siv hluav taws xob, txo qhov hloov pauv lub cev loj.
Anti-Resonance Peev Xwm: Kev teeb tsa ze rau ntawm cov tub ntxhais transformer minimizes internal kev twb kev txuas cable capacitance, txo qhov kev pheej hmoo ntawm ferroresonance.
Kev khiav hauj lwm Mechanism: Siv manually them tshaj -toggle cia lub caij nplooj ntoos hlav sib dhos. Qhov kaw thiab qhib nrawm yog ywj siab ntawm kev khiav hauj lwm ceev, kom ntseeg tau tias muaj kev ruaj ntseg arc extinction.
4. Cov lus pom zoo xaiv rau koj qhov chaw nres tsheb
Yog tias koj tab tom qhia lossis yuav khoom rau koj qhov project, nws raug nquahu kom txhais cov cai raws li cov hauv qab no:
Yuav tsum muaj kev nyab xeeb nruj (piv txwv li, Cov Chaw Cov Ntaub Ntawv, Cov Tsev Kho Mob): Yuav tsum xaiv Cov Hniav Xaiv (Hom D/R), ua kom "Tso Ua Ntej Ua" kom tshem tawm txhua qhov kev pheej hmoo ntawm kev tsis sib haum xeeb.
Kev Ua Haujlwm Txuas Ntxiv (piv txwv li, Kev Lag Luam Hauv Cheeb Tsam, Chaw Ua Lag Luam Muaj): Tej zaum yuav xaiv V-Hloov kom ua tiav qhov kev hloov pauv seamless, tab sis xyuas kom cov chaw ntws ntws muaj peev xwm synchronization.
Parameter Verification:
Rated Voltage: Kev ntsuam xyuas 15kV / 25kV / 35kV.
Rated Tam sim no: Kev lag luam tus qauv feem ntau yog 630A.
