Lub luag haujlwm ntawm High -Voltage Reactors hauv Substations yog dab tsi?
Nov 13, 2025| Nyob rau hauv lub zog hluav taws xob, substations tsis yog tsuas yog lub luag hauj lwm rau kev sib kis thiab kev faib hluav taws xob lub zog tab sis kuj ua lub luag haujlwm tseem ceeb hauv kev ua kom lub zog zoo thiab kev ua haujlwm ruaj khov ntawm daim phiaj.
I. Lub Siab -Voltage Reactor yog dab tsi?
Lub siab -voltage reactor yog ib qho khoom siv hluav taws xob passive feem ntau yog tus cwj pwm los ntawm nws qhov inductance. Nws feem ntau muaj cov tub ntxhais hlau, windings, rwb thaiv tsev qauv, thiab cua txias system. Nws lub ntsiab feature yog ib tug loj inductance nqi. Thaum tam sim no dhau los ntawm nws, qhov induced voltage yog generated hla lub reactor, yog li txwv tus nqi ntawm tam sim no hloov los yog suppressing harmonic tam sim no.
II. Lub luag haujlwm tseem ceeb ntawm High-Voltage Reactors hauv Substations
1. Tiv thaiv luv luv -Circuit Currents
Thaum lub sijhawm ua haujlwm hauv kab sib chaws, yog tias qhov luv luv - Circuit Court txhaum tshwm sim, qhov tam sim no tuaj yeem surges sai sai, uas yuav ua rau switchgear burnout, busbar deformation, los yog txawm lub cev qhuav dej. Hauv cov xwm txheej zoo li no, siab -voltage reactors ua "tam sim no limiters." Los ntawm leveraging lawv inductive impedance, lawv txwv qhov nce ntawm luv luv -circuit tam sim no thiab ncua lub sij hawm sawv tam sim no, yuav lub sij hawm tseem ceeb teb rau cov khoom tiv thaiv (xws li Circuit Court breakers thiab relay tiv thaiv systems). Qhov no zoo tiv thaiv cov cuab yeej puas tsuaj thiab txo qhov nce ntawm qhov tsis raug.
2. Txhim kho lub zog ua haujlwm
Substations feem ntau ntiav cov tsev txhab nyiaj shunt capacitor los them rau lub zog reactive thiab txhim kho lub zog. Txawm li cas los xij, cov capacitors no tuaj yeem cuam tshuam nrog kev sib haum xeeb, ua rau cov khoom puas lossis qhov tsis sib haum xeeb. Los ntawm kev sib txuas siab -voltage reactors nyob rau hauv series nrog lub tsev txhab nyiaj capacitor, harmonic tam sim no los ntawm kab sib chaws tuaj yeem tiv thaiv tau zoo, tiv thaiv capacitor overcurrent.
3. Stabilizing System Voltage
Hauv cov kab sib txuas nrog cov kab sib txuas ntev lossis kev hloov pauv loj, qhov hluav taws xob feem ntau tshwm sim los yog poob, cuam tshuam rau cov khoom siv ua haujlwm. Shunt reactors tuaj yeem nqus tau ntau lub zog reactive hauv lub cev, tiv thaiv qhov hluav taws xob tsis zoo thaum lub teeb ci -load tej yam kev mob.
4. Tiv thaiv kev cuam tshuam ntawm Harmonic
Cov tshuab hluav taws xob niaj hnub no muaj ntau yam khoom siv uas tsis yog-linear (xws li zaus hloov pauv, arc furnaces, thiab rectifiers), uas zoo li ua kom muaj kev sib haum xeeb thiab ua rau lub zog tsis zoo.
Filter reactors ntsia nyob rau hauv substations, ua ke nrog lim capacitors, daim ntawv lim circuits uas zoo nqus cov kev txiav txim ntawm harmonic tam sim no. Qhov no tiv thaiv kev sib haum xeeb los ntawm kev nthuav tawm los ntawm lub cev, yog li tiv thaiv transformers, keyboards, thiab lwm yam khoom siv los ntawm kev puas tsuaj.
