6-220kV siab voltage Reactor
Reactors
Reactors, tseem hu ua inductors, yog siv dav hauv circuits. Vim yog cov nyhuv electromagnetic induction, muaj qee qhov kev cuam tshuam ntawm inductance hauv Circuit Court, uas tuaj yeem tiv thaiv kev hloov pauv tam sim no. Thaum tus neeg xyuas pib muaj zog, qhov chaw sib nqus yog tsim nyob rau hauv ib qho chaw ntawm qhov chaw nws nyob, yog li tag nrho cov khoom siv hluav taws xob tam sim no muaj kev nkag siab ntawm inductance. Txawm li cas los xij, qhov inductance ntawm tus neeg xyuas pib ntev thiab ncaj yog qhov me me, thiab cov hlau nplaum tsim tawm tsis muaj zog. Yog li ntawd, qhov tseeb reactor yog ib tug hlau qhov txhab nyob rau hauv daim ntawv ntawm ib tug solenoid, hu ua ib tug hollow reactor;
Qee lub sij hawm, txhawm rau txhawm rau nce qhov inductance ntawm lub solenoid no, cov tub ntxhais hlau tau muab tso rau hauv lub solenoid, uas yog hu ua cov tub ntxhais hlau reactor. Reactance muab faib ua inductive reactance thiab capacitive reactance. Ib qho kev faib tawm ntau dua yog tias inductive reactance (inductor) thiab capacitive reactance (capacitor) raug xa mus ua cov reactors. Txawm li cas los xij, vim muaj cov inductors yav dhau los, uas tau hu ua reactors, capacitors tam sim no hu ua capacitive reactances, thiab reactors tshwj xeeb yog xa mus rau inductors.
Cov reactors feem ntau siv hauv cov tshuab hluav taws xob muaj xws li cov reactors series thiab parallel reactors. Series reactors feem ntau yog siv los txwv cov luv luv-circuit tam sim no, thiab tseem tuaj yeem txuas rau hauv series lossis sib npaug nrog cov capacitors hauv cov ntxaij lim dej kom txwv tsis pub muaj kev sib raug zoo hauv kab hluav taws xob. Reactors nyob rau hauv 220kV, 110kV, 35kV, thiab 10kV fais fab grids yog siv los nqus capacitive reactive zog los ntawm cable kab thaum them nyiaj. Kev khiav hauj lwm voltage tuaj yeem hloov kho los ntawm kev kho tus naj npawb ntawm cov khoom sib txuas. Ultra high voltage parallel reactors muaj ntau yam kev ua haujlwm los txhim kho cov haujlwm ua haujlwm ntsig txog lub zog reactive hauv lub zog hluav taws xob, feem ntau suav nrog: 1. Cov nyhuv capacitance ntawm cov khoom siv hluav taws xob tsis zoo los yog cov kab me me kom txo tau cov hluav taws xob overvoltage ntawm lub zog zaus; 2. Txhim kho qhov kev faib hluav taws xob ntawm cov kab txuas mus ntev; 3. Txhawm rau sib npaug ntawm lub zog reactive nyob rau hauv kab kom ntau li ntau tau ntawm qhov chaw thaum lub teeb loads, tiv thaiv tsis tsim nyog ntws ntawm reactive zog thiab txo lub zog poob ntawm txoj kab; 4. Txo qhov tsis tu ncua ntawm lub zog ntawm lub zog zaus ntawm lub tsheb npav high-voltage thaum lub tsev loj nyob rau tib lub sijhawm, ua rau nws yooj yim dua rau lub tshuab hluav taws xob synchronized thiab parallel; 5. Tiv thaiv tus kheej excitation resonance tshwm sim uas yuav tshwm sim nyob rau hauv lub tshuab hluav taws xob nrog cov kab ntev; 6. Thaum siv lub reactor nruab nrab taw tes los ntawm ib tug me me reactance grounding ntaus ntawv, ib tug me me reactor kuj yuav siv tau los them rau cov theem mus rau theem thiab theem mus rau hauv av capacitance ntawm txoj kab, thiaj li yuav ceev lub automatic extinguishing ntawm lub latent tam sim no thiab yooj yim rau nws siv. Kev xaim ntawm cov reactors tuaj yeem muab faib ua ob txoj hauv kev: kev sib txuas sib txuas thiab kev sib txuas ua ke. Series reactors feem ntau ua haujlwm raws li cov cuab yeej txwv tam sim no, thaum cov khoom siv hluav taws xob sib txuas feem ntau siv rau cov nyiaj them rov qab hluav taws xob.
