Yuav Ua Li Cas Siab -voltage Series Reactors Ncua Tam Sim No Thaum Hloov Siv Lawv Cov Yam Ntxim Ua Inductive?

High voltage series reactor siv lawv cov yam ntxwv inductive kom muaj txiaj ntsig zoo rau cov excitation inrush tam sim no. Lawv lub hauv paus ntsiab lus yog ua raws li inductance tsis kam mus rau qhov hloov pauv tam sim no. Ntawm no yog ib qho kev sib cais:
I. Inductive yam ntxwv: tsis kam mus rau tam sim no hloov tam sim no.
ii. Kev qhia lej ntawm Inrush tam sim no txwv
Qhov ntau (K) ntawm excitation inrush tam sim no yog ze ze rau inductive reactance (XL) thiab capacitance (XC) ntawm lub reactor.
Qhov no txhais tau hais tias los ntawm serializing tus qauv reactor ntawm 6%, qhov inrush tam sim no tuaj yeem raug txwv los ntawm 100 npaug ntawm qhov ntsuas tam sim no mus rau kwv yees li 5 zaug, txo qhov cuam tshuam ntawm cov capacitors thiab cov khoom siv hloov pauv.
III. Kev xaiv ntawm Reactance Ratio thiab Cov nyhuv ntawm Inrush Current Constraint
Qhov sib piv reactance (K%) yog qhov piv ntawm inductance ntawm cov reactor series mus rau lub capacitor capacitor. Nws txoj kev xaiv ncaj qha cuam tshuam rau qhov inrush tam sim no txwv cov nyhuv:
Tsawg reactance ratio (0.1% ~ 1%): Haum rau cov ntsiab lus tsis sib haum xeeb ntawm daim phiaj, lub hom phiaj tseem ceeb ntawm kev txwv tsis pub nkag. Nyob rau hauv cov ntaub ntawv no, lub active zog poob ntawm lub reactor yog tsawg, qhov loj me me, lub hauv pem teb cheeb tsam yog me me thiab nws yog ib qho yooj yim rau nruab nyob rau hauv capacitor banks. Piv txwv li, kev siv 0.5% reactance piv tuaj yeem txwv qhov inrush mus rau 15 npaug ntawm qhov ntsuas tam sim no.
Standard reactance ratio (6%): siv rau feem ntau industrial thiab nroog substations, zoo txwv inrush mus rau kwv yees li 5 zaug thaum tsis txhob harmonic amplification (xws li . 5 zaus harmonic).
High reactance (12% ~ 13%): Haum rau cov ntsiab lus siab sib haum xeeb hauv daim phiaj fais fab. Cov yam ntxwv harmonics yog suppressed los ntawm kev kho lub capacitor bank pawg thiab reactor los tsim ib feem resonant circuit.
IV. INTRODUCTION Reactor tiv thaiv capacitors thiab tshuab
Kev Tiv Thaiv Capacitor: Inrush tuaj yeem ua rau muaj kev ntxhov siab zoo thiab thermal uas ua rau muaj kev puas tsuaj rau cov phaj capacitor, fuses lossis thaiv. Series reactors ncua lub neej capacitor los ntawm kev txwv qhov excitation inrush tam sim no.
Kev tiv thaiv switchgear: Inrush tam sim no tuaj yeem ua rau hluav taws xob hluav taws xob tiv thaiv kev yaig lossis tus contactor rov- tawg, ua rau kev ua haujlwm dhau qhov hluav taws xob. Reactor txo kev puas tsuaj rau kev hloov khoom siv los ntawm kev txo qis inrush tam sim no amplitude.
Kev Tiv Thaiv ntawm Harmonic Amplification: Reactors thiab capacitor banks tsim LC lim Circuit Court uas resonate ntawm ib qho kev sib haum xeeb zaus, tiv thaiv cov kev sib raug zoo tam sim no los ntawm kev ntws mus rau hauv daim phiaj hluav taws xob lossis cov khoom nyob ze, thiab txhim kho lub zog zoo.
V. Kev ceev faj ntsuas hauv kev siv tswv yim
Reactor linearity: Txhawm rau zam kom tsis txhob muaj kev sib haum xeeb, lub voltammetry ntawm cov reactors series yuav tsum yog raws li qhov ua tau kom muaj kev ruaj khov inductive reactance nyob rau hauv txawv tam sim no.
Reactor muaj peev xwm sib piv: reactor muaj peev xwm yuav tsum raug xaiv raws li qhov ntsuas tam sim no ntawm lub txhab nyiaj capacitor thiab luv luv - Circuit Court muaj peev xwm ntawm lub kaw lus, kom tsis txhob txo qhov txo qis lossis nce tus nqi ntawm lub peev xwm ntau dhau.
Installation qhov chaw: Reactor feem ntau yog serialized nyob rau hauv Circuit Court breaker sab los yog nruab nrab sab ntawm lub txhab nyiaj capacitor. Xyuas kom muaj kev sib txuas ruaj ntseg thiab qhov cua zoo kom tsis txhob muaj cua sov hauv zos.
