Description
technical field [0001] The invention relates to a rapid icing device for an experimental overhead transmission line, which is used for rapidly icing the experimental overhead transmission line to ensure the accuracy of the experiment. Background technique [0002] The icing and snow accumulation of transmission lines have long threatened the safe operation of power systems. Ice shedding often causes major accidents such as phase-to-phase flashover of transmission line conductors, disconnection, and tower collapse, which poses a serious hazard to the safe operation of power systems. UHV line conductors have a larger cross-section, more conductor splits, and greater ice weight, which is more likely to cause large jumps when deicing; therefore, in the design of UHV transmission lines, especially in heavy ice areas , to determine the layout of the transmission line, the selection of the tower, the configuration of the span, etc., it is necessary to focus on the problem of deicin...
