Title:AnalysisofAnomaliesinExtra-HighVoltageReactorsBasedonAcetyleneDissolvedinOilandPartialDischarge
Abstract:
Thispaperaimstoanalyzeanomaliesinextra-highvoltagereactorsbyinvestigatingthepresenceofacetylenedissolvedinoilandpartialdischarge.Extra-highvoltagereactorsarecriticalcomponentsinelectricalpowertransmissionanddistributionsystems.Anyabnormalitiesinthesereactorscanhavesevereconsequences,includingpoweroutagesandequipmentdamage.Therefore,understandingthecausesandpotentialsolutionsforanomaliesinextra-highvoltagereactorsisnecessarytoensurepowersystemreliabilityandstability.
Introduction:
Extra-highvoltagereactorsareusedtocontrolvoltagelevelsinpowertransmissionanddistributionnetworks.Duetothehigh-voltageoperatingenvironment,thesereactorsarevulnerabletovariousanomalies,includingacetylenedissolutioninoilandpartialdischarge.Acetyleneisknowntodegradetheinsulationpropertiesofoil,leadingtoreducedreactorperformance.Additionally,partialdischargecausedbyinsulationdegradationcontributestothedeteriorationofthereactor.Therefore,acomprehensiveanalysisoftheseanomaliesisessentialforpreventingfailuresinextra-highvoltagereactors.
1.InvestigationofAcetyleneDissolvedinOil:
1.1SourcesofAcetylene:Thissectionexploresthepotentialsourcesofacetylene,suchasgasleaksandabnormaloperatingconditions.Thepresenceofacetyleneinoilcanbeindicativeofinsulationdegradationorpotentialfailurepoints.
1.2EffectsofAcetyleneDissolution:Theimpactofacetyleneonoilandreactorperformanceisdiscussed,focusingonissuesrelatedtoinsulationbreakdownandelectricaldischarges.Emphasisisplacedonitscontributiontopartialdischargeevents.
2.PartialDischargeAnalysis:
