cov khoom piav qhia

Tam sim no, lub zog hluav taws xob ua haujlwm tseem ceeb heev rau kev txuag hluav taws xob thiab txo qis.Pib los ntawm kev tswj cov hluav taws xob hluav taws xob thiab hluav taws xob reactive, ntau cov nyiaj tau nqis peev los tsim ntau qhov voltage thiab reactive fais fab tswj software.VQC, on-load kais hloov pauv, Reactive fais fab nyiaj them nyiaj shunt capacitor bank thiab lwm yam khoom siv, qhov hluav taws xob zoo tau txhim kho zoo.Txawm li cas los xij, vim qhov rov qab ntawm cov kev hloov pauv hluav taws xob rov qab thiab cov teeb meem xws li overvoltage, overcurrent, thiab lifespan hauv kev ua haujlwm ntawm capacitors, qhov voltage thiab reactive fais fab tswj software tsis tuaj yeem ua nws lub luag haujlwm, thiab tsis tuaj yeem khaws cov ntsuas qhov xav tau rau voltage thiab reactive zog.Cov txiaj ntsig kev lag luam thiab kev lag luam tsis tuaj yeem ua tiav, thiab cov peev txheej ntawm cov cuab yeej siv tsis tuaj yeem siv tag nrho.

Lub hom phiaj ntawm qhov rov qab ntawm qhov hluav taws xob thiab kev hloov hluav taws xob reactive, peb lub tuam txhab tau tsim ib hom tshiab ntawm substation voltage thiab reactive fais fab tsis siv neeg hloov kho cov cuab yeej raws li kev nqus cov thev naus laus zis tshiab hauv tsev thiab txawv teb chaws.Cov zis muaj peev xwm hloov tau los ntawm kev kho qhov hluav taws xob ntawm ob qho kawg ntawm lub capacitor, uas daws cov teeb meem ntawm overvoltage thiab inrush tam sim no nyob rau hauv lub lag luam ntawm lub capacitor, thiab hloov hysteresis hloov mus rau real-time hloov.Lub substation voltage thiab reactive fais fab tsis siv neeg hloov kho khoom siv kuj tseem tuaj yeem hloov kho cov kab hluav taws xob txuas txuas mus rau hauv ib qho kev hloov kho inductive reactive zog them nyiaj ntaus ntawv.Kev nrov nrov thiab kev siv cov cuab yeej no tuaj yeem txhim kho kev tswj hwm qib ntawm qhov hluav taws xob thiab lub zog reactive, uas tuaj yeem txo cov kab hluav taws xob poob qis, txhim kho lub zog zoo, txhim kho qib kev nyab xeeb ntawm cov cuab yeej, ua kom cov txiaj ntsig kev lag luam ntawm kev lag luam fais fab. , thiab txhim kho lub peev xwm muab hluav taws xob tsis tsim cov chaw tsim hluav taws xob tshiab.Pab kom daws tau qhov teeb meem tam sim no hauv tsev hluav taws xob tsis txaus.

Scope ntawm daim ntawv thov

Cov khoom lag luam yog tsim nyog rau txhua theem ntawm cov chaw nres tsheb uas muaj qhov hluav taws xob ntawm 6KV ~ 220KV, thiab tau nruab rau ntawm 6KV / 10KV / 35KV busbars ntawm substations.Cov khoom siv dav siv hauv cov tshuab hluav taws xob, metallurgy, thee, petrochemical thiab lwm yam kev lag luam los txhim kho qhov hluav taws xob zoo, ua kom muaj zog, thiab txo cov kab poob.

Technical Parameters

Lub hauv paus ntsiab lus ntawm ntaus ntawv
Lub zog hluav taws xob thiab lub zog reactive tsis siv neeg hloov kho ntawm lub substation txais kev sib txuas ruaj khov ntawm cov capacitor yam tsis muaj kev sib koom ua ke, thiab cov nyiaj them poob haujlwm ntawm lub capacitor hloov pauv los ntawm kev hloov qhov voltage ntawm ob qho kawg ntawm lub capacitor.Raws li lub hauv paus ntsiab lus ntawm Q = 2πfCU2, qhov voltage thiab C tus nqi ntawm lub capacitor tseem tsis hloov, thiab qhov voltage ntawm ob kawg ntawm lub capacitor hloov.Tso zis ntawm reactive zog.
Nws cov zis muaj peev xwm hloov tau qhov tseeb thiab qhov tob ntawm kev tswj hluav taws xob ntawm (100% ~ 25%) x Q, uas yog, qhov kev hloov kho qhov tseeb thiab qhov tob ntawm cov capacitors tuaj yeem hloov pauv.
Daim duab 1 yog daim duab thaiv ntawm lub hauv paus ntsiab lus ua haujlwm ntawm lub cuab yeej:

Cov khoom siv muaj pes tsawg leeg

Lub voltage-regulating tsis siv neeg them nyiaj ntaus ntawv yog tsim los ntawm peb qhov chaw, uas yog lub voltage regulator, tag nrho cov capacitors thiab lub voltage thiab reactive hwj chim tswj vaj huam sib luag.Daim duab 2 yog lub hauv paus schematic daim duab ntawm lub cuab yeej:

Voltage regulator: Lub regulator txuas lub capacitor mus rau lub busbar, thiab hloov cov zis voltage ntawm lub capacitor nyob rau hauv lub premise ntawm kev ruaj ntseg ntawm lub busbar voltage, thiaj li yuav xyuas kom meej tias cov zis muaj peev xwm ntawm lub capacitor ua tau raws li qhov system yuav tsum tau.Voltage thiab reactive fais fab tswj vaj huam sib luag: Raws li cov tswv yim tam sim no thiab voltage signals, kais txiav txim yog ua, thiab cov lus txib raug muab los kho lub ntsiab transformer kais dej ntawm lub substation los kho qhov voltage los xyuas kom meej lub pass tus nqi ntawm lub tsheb npav voltage.Kho qhov tso zis voltage ntawm lub voltage regulator los hloov lub reactive zog tso zis ntawm lub capacitor.Thiab muaj cov khoom siv sib xws thiab cov teeb liab ua haujlwm.Capacitive reactive zog qhov chaw ntawm lub capacitor tiav teeb.
