Abstract

The invention discloses a method for utilizing a visibility model to predict an icing thickness of a transmission line. The method is used for solving the problems of the prior art that the manual observation is very dangerous, the working condition of workers is hard, the living is difficultly guaranteed and the investment cost is higher. The method comprises the following steps: 1) collecting lead icing data and weather factor data in a place in which the transmission line is located; respectively settling the lead icing data and the weather factor data collected in the first step along vertical and longitudinal directions; 3) respectively performing corresponding statistics on the data settled in the second step; and 4) substituting the settled data into a fitting formula, thereby acquiring the icing thickness of the transmission line. The method is used for utilizing the visibility model to predict the icing thickness of the transmission line, so as to support ice-resisting (ice-preventing) arrangement and design of an iced transmission line.

Description

technical field [0001] The invention relates to a method for predicting the ice thickness of a power transmission line by using a visibility model. Background technique [0002] Conductor icing refers to the natural phenomenon that ice crystals accumulate around the conductor under certain meteorological conditions. Conductor icing will increase the load on the wire and tower, leading to accidents. There are three main types of accidents caused by wire icing: (1) Overload accidents, which are mainly caused by the mechanical and electrical damage caused by the increase in the ice-coated wire over the design ice-resistant thickness, that is, the increase in mass and wind pressure area (2) Accidents caused by uneven icing or deicing at different periods, mainly due to uneven icing of adjacent gears or different periods of deicing of lines resulting in tension differences, thus damaging fittings, conductors and insulators or causing conductors to Flashover due to reduction of e...
