Dab tsi ua rau lub tshuab hluav taws xob hauv qab voltage

Lub tshuab hluav taws xob yog cov cuab yeej siv tshuab uas hloov pauv lwm hom hluav taws xob rau hauv hluav taws xob hluav taws xob.Nws yog tsav los ntawm cov dej turbine, chav turbine, lub cav diesel lossis lwm lub tshuab fais fab, thiab hloov lub zog tsim los ntawm cov dej ntws, airflow, roj combustion lossis nuclear fission rau hauv lub tshuab hluav taws xob thiab xa mus rau lub tshuab hluav taws xob.Hloov mus rau hluav taws xob los ntawm lub tshuab hluav taws xob.Cov tshuab hluav taws xob tau siv dav hauv kev lag luam thiab kev ua liaj ua teb, kev tiv thaiv hauv tebchaws, kev tshawb fawb thiab thev naus laus zis thiab lub neej niaj hnub.

Muaj ntau hom ntawv cov tshuab hluav taws xob , tab sis lawv cov qauv kev ua haujlwm yog raws li txoj cai ntawm electromagnetic induction thiab txoj cai ntawm electromagnetic quab yuam.Yog li ntawd, lub hauv paus ntsiab lus ntawm nws txoj kev tsim kho yog: siv cov khoom sib nqus thiab cov khoom siv hluav taws xob tsim nyog los tsim cov hlau nplaum sib nqus thiab cov circuits uas ua rau electromagnetic induction nrog ib leeg los tsim hluav taws xob electromagnetic thiab ua tiav lub hom phiaj ntawm kev hloov hluav taws xob.

Dab tsi ua rau lub tshuab hluav taws xob nyob rau hauv voltage?

(1) Qhov ceev ntawm lub prime mover yog tsawg dhau.

(2) Qhov kev tiv thaiv ntawm lub excitation Circuit Court yog loj heev

(3) Cov txhuam txhuam exciter tsis nyob ntawm qhov nruab nrab, lossis lub caij nplooj ntoos hlav siab me dhau.

(4) Qee qhov rectifier diodes tau tawg.

(5) Muaj qhov luv luv lossis hauv av txhaum hauv stator winding lossis excitation winding.

(6) Kev sib cuag ntawm tus txhuam hniav me dhau, lub siab tsis txaus, thiab kev sib cuag tsis zoo.Yog tias nws yog tshwm sim los ntawm qhov chaw ntawm lub commutator, koj tuaj yeem polish qhov saum npoo ntawm lub commutator nrog emery daim ntaub ntawm qis ceev, los yog kho lub caij nplooj ntoos hlav siab.

Rau cov laj thawj saum toj no, yuav ua li cas nce lub tshuab hluav taws xob hluav taws xob?

1. Kho qhov ceev ntawm lub prime mover rau tus nqi ntsuas.

2. Txo qhov tsis kam ntawm cov magnetic teb rheostat kom cov excitation tam sim no.Rau cov khoom siv hluav taws xob semiconductor excitation, xyuas seb cov pob qij txha txuas ntxiv puas raug txiav lossis tsis raug txuas.

3. Kho cov txhuam hniav kom raug, hloov cov txhuam hniav, kho lub caij nplooj ntoos hlav siab.

4. Tshawb xyuas thiab hloov lub diode tawg.

5. Tshawb xyuas qhov txhaum thiab tshem tawm nws.

Lwm txoj hauv kev los ua kom lub tshuab hluav taws xob muaj zog:

Nce lub excitation hnyav ntawm lub tshuab hluav taws xob;

nce qhov ceev ntawm lub tshuab hluav taws xob;

Txo qhov tsis kam ntawm lub voj voog hauv lub tshuab hluav taws xob;

Lightening ntawm lub load los yog tus nqi ntawm excitation nce thaum lub load nce.

Yuav ua li cas kom lub generator davhlau ya nyob twg voltage tsis hloov

Thaum lub load tam sim no ntawm lub tshuab hluav taws xob hloov, raws li tus yam ntxwv sab nraud nkhaus, lub davhlau ya nyob twg voltage ntawm lub tshuab hluav taws xob yuav hloov nrog nws.

Txhawm rau kom lub davhlau ya nyob twg voltage ntawm lub tshuab hluav taws xob tas li, qhov kev tawm dag zog tam sim no ntawm lub tshuab hluav taws xob yuav tsum tau kho kom haum.

Nyob rau hauv cov xwm txheej ntawm kev ceev ceev, load hwj chim qhov tseem ceeb thiab lub davhlau ya nyob twg voltage tsis hloov, kev sib raug zoo ntawm excitation tam sim no IL thiab lub load ls yog hu ua cov kev cai ntawm lub generator.

Rau kev tiv thaiv thiab inductive loads, raws li cov load tam sim no nce, lub davhlau ya nyob twg voltage ntawm lub tshuab hluav taws xob yuav maj mam txo.Txhawm rau kom lub davhlau ya nyob twg voltage tsis hloov, qhov excitation tam sim no yuav tsum tau nce raws li kom them rau qhov demagnetization thiab to reactance ntawm armature cov tshuaj tiv thaiv.siab poob.

Rau cov loads capacitive, txij li lub davhlau ya nyob twg voltage ntawm lub tshuab hluav taws xob yuav nce ntxiv nrog rau qhov nce ntawm cov load tam sim no, lub excitation tam sim no yuav tsum raug txo kom offset excitation nyhuv ntawm armature cov tshuaj tiv thaiv thiab cov boosting nyhuv ntawm cov leakage reactance. terminal voltage.tas li.

Cov teeb meem uas yuav tsum tau them sai sai rau thaum sib piv lub tshuab hluav taws xob tsis muaj hluav taws xob nrog lub zog hluav taws xob: thaum lub sijhawm hloov thiab kaw, lub tshuab hluav taws xob yuav tsum tsis txhob muaj teeb meem tam sim no, thiab cov ncej tig yuav tsum tsis txhob poob siab tam sim ntawd.

Tom qab kaw, lub rotor yuav tsum tau rub mus rau hauv synchronization sai sai (uas yog, lub rotor ceev yog sib npaug rau qhov ntsuas ceev).Vim li no, lub tshuab hluav taws xob synchronous yuav tsum ua raws li cov hauv qab no:

1. Tus nqi zoo ntawm cov generator voltage yuav tsum sib npaug rau tus nqi zoo ntawm daim phiaj voltage.

2. Cov theem ntawm lub tshuab hluav taws xob voltage thiab theem ntawm daim phiaj hluav taws xob yuav tsum zoo ib yam.

3. Qhov zaus ntawm lub tshuab hluav taws xob yog sib npaug rau qhov zaus ntawm daim phiaj.

4. Cov theem ua ntu zus ntawm lub tshuab hluav taws xob hluav taws xob yog ua raws li theem ua ntu zus ntawm daim phiaj hluav taws xob.

5. Nws yog txwv tsis pub xa hluav taws xob rov qab rau hauv daim phiaj hluav taws xob.
