Improvement of methods for determining icing load on the conductors of overhead lines
Abstract: The paper deals with numerical simulation and experimental investigations of icing on the conductors of overhead power transmission lines, interaction of glaze ice with conductor, as well as some aspects of the influence of wind direction on the icing on the conductor. There was a computer program based on the model Makkonen that lets you perform a theoretical simulation of the icing with stiffness in torsion of the conductor. Made up the differential equation of the angle of twist the conductors under the eccentric ice load. To determine the combined effect of wind speed and direction on the parameters icing deposits performed studies using the experimental setting on the base of climatic chamber of laboratory of tests of build constructions and buildings of the DonNACEA. Found that the ice load leads to an intense single twisting power lines, wind direction affects the shape and structure of glaze ice.
Keywords: overhead transmission lines (OHL), conductor, icing, stiffness in torsion, the numerical simulation, experimental investigations.
