| description | In the presence of wind and the deposition of ice on the overhead power lines, mechanical oscillations of the wires are observed, characterized by a relatively low frequency and considerable amplitude ("dance" of wires). As a result of the “dance”, melting and burning of wires occurs due to short circuits, damage and breakage of supports, garlands of insulators and other elements of transmission lines. The article reviews a brief overview of the current state of the issue and formulates the purpose and objectives of the study. The main goal of the scientific article is the development of an engineering method for calculating the frequency characteristics of a split-phase dance with reference to an anchor span. The basis of the developed method is the analysis of the energy balance of the oscillatory process and the mathematical model of the dance of wires. The problem is limited to vertical one-half-wave oscillations of the split phase. The developed calculation formula establishes the relationship between the frequency of dancing, wind speed, aerodynamic characteristics of the icy wire and the parameters of the overhead line. The formula for determining the dance frequency can be used to solve various applied problems. |
