输电线路脱冰跳跃研究及防治（英文） ResearchandPreventionofConductorLineDe-icingLeap Introduction: Duringwinter,theaccumulationoficeonpowertransmissionlinesposesasignificantrisktothestabilityandreliabilityoftheelectricalgrid.Icebuildupontheconductorlinescanleadtoincreasedweight,sagging,andevenbreakage,whichcanresultinpoweroutagesanddamagetoinfrastructure.Therefore,itiscrucialtostudyanddevelopeffectivemethodsforde-icingandpreventiontomaintaintheuninterruptedsupplyofelectricity.Thispaperaimstoexplorevariousresearcheffortsandpreventivemeasuresforconductorlinede-icingleap. I.De-icingTechniques: 1.MechanicalMethods: a.Ice-phobicCoatings:Applyingice-phobiccoatingsontransmissionlineconductorscanpreventtheaccumulationoficebyreducingtheadhesionbetweeniceandthesurface.Thesecoatingscanbemadeofmaterialssuchashydrophobicpolymers,whichrepelwaterandice,preventingthemfromadheringtothesurface. b.VibrationalMethods:Applyingvibrationtotheconductorscanhelpbreaktheice'sadhesion.Vibrationaldevicescanbeattachedtothetransmissionlinestocreateoscillationsthatshakeofftheicebuildup. 2.ThermalMethods: a.ResistiveHeating:Bypassinganelectriccurrentthroughtheconductors,theresistanceofthewiregeneratesheat,whichcaneffectivelymelttheice.Resistiveheatingcanbecontrolledandoptimizedtopreventexcessiveenergyconsumption. b.InductiveHeating:Inductiveheatinguseselectromagneticfieldsgeneratedbyinductionsystemstoheattheconductors.Thismethodheatstheconductoruniformly,providingefficientde-icing.
