Yuav Ua Li Cas Tiv Thaiv Cov Loops hauv Parallel Ua Haujlwm ntawm Generator

Kev ua haujlwm Parallel txhais tau hais tias ob lossis ntau lub tshuab hluav taws xob teeb tsa nrog qhov sib npaug ntawm qhov ntsuas hluav taws xob thiab cov theem sib xws tau muab tso rau hauv tib lub tsheb npav los muab lub zog muaj zog thiab muaj peev xwm rov ua haujlwm rau lub cuab yeej.Ib lub tshuab hluav taws xob tau pib ua ntej, thiab tom qab ntawd cov hluav taws xob generated raug xa mus rau lub tsheb npav.Tom qab lwm lub tshuab hluav taws xob tau pib, nws yog nyob rau tib lub sijhawm nrog lub tshuab hluav taws xob dhau los teeb tsa lub sijhawm no.Thaum lub sijhawm kaw, lub tshuab hluav taws xob teeb yuav tsis muaj qhov txawv txav tam sim no, thiab lub crankshaft yuav tsis raug cuam tshuam tam sim ntawd.Txawm li cas los xij, tag nrho tam sim no Circuit Court yuav tsum tau muab xam rau hauv cov kauj ruam ua haujlwm ntawm kev ua haujlwm sib luag.

1. Rov qab ua haujlwm.Qhov teeb meem tam sim no ntawm lub hwj chim rov qab yog tshwm sim los ntawm qhov sib txawv ceev thiab voltage ntawm generator units , uas yog, ib lub tshuab hluav taws xob muaj lub zog zoo thiab lwm chav muaj lub zog tsis zoo.Hauv lwm lo lus, chav tsev nrog lub peev xwm tsis zoo dhau los ua lub nra ntawm lub sijhawm no (qhov xwm txheej tam sim no ntawm qhov tsawg zaus thiab qhov tsis sib xws ntawm chav tsev no).Thaum qhov hluav taws xob tsis sib haum, chav tsev uas muaj qhov hluav taws xob siab muab ib qho hluav taws xob tam sim no thiab qhov hluav taws xob reactive rau chav tsev uas tsis muaj hluav taws xob (qhov qhia tau zoo ntawm ammeter ntawm chav tsev no).Nws yog sib npaug rau kev ntxiv ib pawg condenser hauv cov khoom siv hluav taws xob.Lub sijhawm no, chav tsev uas tsis tshua muaj hluav taws xob dhau los ua lub nra hnyav thiab tau txais lub zog loj tam sim no kom ntseeg tau tias qhov sib npaug ntawm ob chav nyob (lub ammeter ntawm chav tsev no qhia rov qab).Thaum lub sij hawm saib xyuas, thaum qhov voltage ntawm ib chav tsev yog nce los yog qhov voltage ntawm lwm chav tsev yog nce, ib chav tsev muaj reverse hwj chim tam sim no, thiab nws tus cwj pwm tam sim no yog hais txog 20% ​​ntawm cov ntsuas tam sim no.Rov qab ua yeeb yam relay ua, mus ncig ua si thiab tswb, tab sis tsis kaw.

2. Overcurrent.Cov zis muaj peev xwm ntawm cov khoom siv hluav taws xob niaj hnub no yog qhov sib txuam, thiab nws cov qib overload yog tsawg heev.Feem ntau ntawm lawv yog nyob ib ncig ntawm 5% ntawm cov zis muaj peev xwm.Lub sijhawm thauj khoom tso cai yog 15 ~ 30 feeb, mus txog 60 feeb.Nyob rau lub sijhawm no, lub Perkins generator teeb yuav kub, rwb thaiv tsev ntawm cable yuav raug txo, thiab kev pab cuam lub neej yuav raug txo.Yog li, yog tias tsis muaj qhov tshwj xeeb yuav tsum tau ua thaum teeb tsa kev tiv thaiv overcurrent, kev tiv thaiv overcurrent tuaj yeem raug teeb tsa ntawm 110% ntawm cov ntsuas tam sim no.Thaum lub sij hawm kuaj load, nqa tam sim no mus rau 110% ntawm cov ntsuas tam sim no, thiab cov overcurrent relay ua.Kev mus ncig, tswb thiab tsis kaw.

3. Tshaj dhau.Thaum lub tshuab hluav taws xob teeb siv nyob rau hauv parallel, nws yog qhov ntshai tshaj plaws ntawm qhov oscillation ntawm lub hwj huam mov system.Thaum lub oscillation tshwm sim, qhov hluav taws xob nce ntawm qhov system yog ib qho yooj yim los tsim cov rwb thaiv tsev tawg ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, uas ua rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tsis tuaj yeem ua haujlwm li qub.Yog li ntawd, cov khoom siv hluav taws xob siv nyob rau hauv tib lub sijhawm yog nruab nrog kev tiv thaiv overvoltage, thiab nws cov nqi preset ntawm 105% ntawm qhov ntsuas hluav taws xob zoo dua.luv Circuit Court overvoltage relay, mus txawv tebchaws, kaw thiab tswb.Nws tuaj yeem pom tau tias qhov kev hloov ceev (ntau zaus) ntawm ob chav nyob yuav tsum ua kom zoo ib yam ua ntej npaj rau kev ua haujlwm sib luag ntawm lub tshuab hluav taws xob.Nyob rau hauv parallel, qhov ceev ntawm thawj lub tshuab los yog cov pab pawg yuav tsum paralleled tuaj yeem hloov kho raws li qhov kev sib hloov ceev ntawm lub rooj nyob rau tib lub sij hawm, kom cov kev sib hloov ntawm lub rooj nyob rau tib lub sij hawm yuav tig clockwise los yog counterclockwise. .Qhov qeeb qeeb yog, qhov zoo dua, tab sis lub pointer ntawm lub rooj nyob rau tib lub sij hawm yuav tsum tau tig ua ntej nws tuaj yeem ua ib sab.Thaum kawg, tom qab ib sab ntawm ib sab, xyuas seb qhov tam sim no thiab lub peev xwm ntawm ob chav nyob sib npaug.Yog tias qhov sib txawv loj dhau, kho lub pob qhov nrawm kom lub zog.
