METHOD OF DETERMINING THE PARAMETERS OF THE DEVICE FOR THE PREVENTION OF ICE FORMATION ON POWER LINES
In Russia, China, Canada and some European countries, the problem of icing wires of power lines in the cold season is relevant. The traditional solution is the thermal method, but its low energy efficiency, laboriousness, risk of damage to the wires contribute to the development of alternative ways to combat icing. Shock-vibration methods are considered the most energy-efficient solution for removing ice from wires. The article proposes a methodology for determining the parameters of the shock principle of action to prevent icing by removing droplets of water before they freeze. Removing water drops is based on creating inertia by «shaking» the wire with a small amplitude relative to the diameter of the wire and sufficient acceleration. Such an effect on the wire is exerted by the inductor system of the device, the elements of which are repelled from each other under the influence of electromagnetic forces arising from the discharge of the energy storage device. The technique is a phased process. Based on an analysis of the parameters of the span and wire, as well as decisions made about the place, the method of mounting the device and its principle of operation, a search is made for the optimal parameters of the impact. Then the calculation of the electrical and mass-dimensional parameters. The article presents the calculation of the installation for a model power transmission span on a reduced scale. The data obtained as a result of calculations by the method can be used to develop a working device.
