Firstly, peb yuav tsum txwv txoj kev sib tham ntawm kev sib tham kom tsis txhob ua rau nws tsis muaj zog heev. Cov tshuab hluav taws xob sib tham ntawm no yog hais txog ib qho txhuam hniav, peb-theem ac synchronous generator, ntawm no ntawm no yog hais tias yog lub tshuab hluav taws xob ".
Cov tshuab hluav taws xob no muaj tsawg kawg peb qhov tseem ceeb, uas yuav hais tawm hauv cov kev sib tham hauv qab no:
Lub tshuab hluav taws xob tseem ceeb, muab faib ua stator tseem ceeb thiab lub rotor tseem ceeb; Lub rotor tseem ceeb muab daim teb sib nqus, thiab lub ntsiab stator tsim hluav taws xob kom muab lub nra; Tsis paub meej, muab faib ua tus qauv zoo nkauj thiab rotor; Tus Exciter stator muab cov chaw sib nqus, lub rotor ua kom muaj hluav taws xob, thiab tom qab kev tsav tsheb sib hloov, nws muab lub zog rau lub rotor tseem ceeb; Tsis siv neeg voltage regulator (avr) ntes cov zis hluav taws xob, thiab ua tiav lub hom phiaj ntawm stegilizing cov zis voltage ntawm lub stator tseem ceeb.
Kev piav qhia txog Avr Voltage stabilization ua haujlwm
Lub hom phiaj ua haujlwm ntawm AVR yog los tswj kev ruaj khov hluav taws xob voltage, feem ntau yog hu ua "voltage stabilizer".
Nws cov haujlwm yog nce stator tam sim no ntawm tus neeg siab tshiab ntawm lub tshuab hluav taws xob tseem ceeb, uas yog sib npaug ntawm lub tshuab hluav taws xob tseem ceeb, ua rau lub tshuab hluav taws xob tseem ceeb rau cov nqi teeb; Ntawm qhov tsis sib xws, txo qhov kev paub zoo thiab cia qhov voltage kom txo qis; Yog tias cov zis hluav taws xob ntawm lub tshuab hluav taws xob yog sib npaug rau cov nqi tsim, Avr tswj hwm cov khoom tso tawm uas twb muaj lawm tsis muaj kev hloov kho.
Tsis tas li ntawd, raws li theem kev sib raug zoo ntawm tam sim no thiab hluav taws xob, AC loads tuaj yeem muab cais ua peb pawg:
Resistive load, qhov twg tam sim no yog nyob rau hauv theem nrog lub voltage thov rau nws; Inductive thauj, cov theem ntawm cov lags tam sim no tom qab lub voltage; Peev npav, cov theem ntawm qhov tam sim no yog ua ntej ntawm qhov hluav taws xob. Ib qho kev sib piv ntawm peb cov yam ntxwv thauj tau pab peb nkag siab zoo ntxiv cov peev txheej.
Rau cov khoom siv tawm, qhov loj dua cov thauj khoom, ntau dua qhov xav tau tam sim no xav tau rau lub ntsiab rotor (txhawm rau ruaj khov cov zis hluav taws xob ntawm lub tshuab hluav taws xob).
Hauv kev sib tham tom ntej, peb yuav siv qhov kev ua kom tiav tam sim no rau cov qauv kev siv, uas tau hais txog qhov loj dua; Peb hu nws me dua nws.
Thaum lub nra ntawm lub tshuab hluav taws xob yog inductive, lub rotor tseem ceeb yuav tsum muaj kev zoo siab dua tam sim no nyob rau hauv kev txiav txim rau lub tshuab hluav taws xob kom ruaj khov rau lub zog hluav taws xob.
Lub peev xwm thauj
Thaum lub tshuab hluav taws xob tau ntsib lub peev xwm hluav taws xob capacite, qhov kev zam dhau los ntawm lub ntsiab roteror yog me dua, uas txhais tau tias qhov kev zoo siab tam sim no yuav tsum tau txo kom ruaj khov rau cov zis hluav taws xob ntawm lub tshuab hluav taws xob.
Vim li cas qhov no tshwm sim?
Peb yuav tsum nco qab tias tam sim no ntawm lub peev xwm ntawm lub colorage, ntws los ntawm lub ntsiab rotorpos, uas tshwm sim los ua kom muaj kev zoo siab tam sim no, txhim kho lub Sib nqus teb ntawm lub ntsiab rotor. Yog li tam sim no los ntawm cov kev paub yuav tsum raug txo kom muaj cov vis dis aus ruaj ruaj ruaj ntawm lub tshuab hluav taws xob.
Qhov loj dua cov peev xwm thauj khoom, cov me me ntxiv ntawm cov kev kawm; Thaum lub twj tso hluav taws xob nce ntxiv rau qee yam, cov zis ntawm cov kev kawm tau yuav tsum raug txo kom xoom. Cov zis ntawm cov kev lom zem yog xoom, uas yog qhov kev txwv ntawm lub tshuab hluav taws xob; Txij ntawm no, cov zis hluav taws xob ntawm lub tshuab hluav taws xob yuav tsis yog tus kheej ruaj khov, thiab hom hluav taws xob tsis tsim nyog. Qhov kev txwv no tseem hu ua 'nyob rau hauv kev npau taws txaus ntshai'.
Lub tshuab hluav taws xob tsuas lees txais muaj txiaj ntsig muaj peev xwm; (Tau kawg, rau lub tshuab hluav taws xob tsis meej, tseem muaj cov kev txwv ntawm qhov loj ntawm kev tiv taus lossis cov khoom siv hluav taws xob.)
Yog tias ib qhov project yog teeb meem los ntawm kev txav peev xwm siv tau, nws yog qhov tsim nyog xaiv los siv nws lub peev xwm siv tau me me captatt, lossis siv cov inductors rau kev them nyiaj. Tsis txhob cia lub tshuab hluav taws xob teeb tsa muaj kev lag luam nyob ze ntawm "hauv qhov kev zam tawm".
