DEVICE FOR MEASURING icing and wind load to control the removal unit ICE with wire overhead power lines

摘要

The invention relates to electric power and can be used for early detection of icing, the selection priority deicing conductors of overhead power lines and to control the plant deicing current pulses of short duration, which provides the mechanical resonance vibrations of the wires.; Technical result of utility model - reducing the time-icing (snow, frost) and a decrease in power consumption. Three force sensor suspended between the support beam and insulator strings to the phase conductors, one garland of insulators fixed to the support on both sides, the second - on the one hand, and the third on the other hand pivotally connected with insulating spacers, is monitored by the signal amplitude of allocating blocks respectively ice load, full load when the wind direction on the one hand and the full load when the wind direction on the other side. These signals are supplied to the nonlinear transformers which generate signals proportional to wind load only at one or the other direction of the wind across the line. Each of the wind load signals telecast on the channel is fed to a third input of two AND gates with three inputs, implementing selection priority. The second input of each AND gate is supplied through the channel TV signal from the first force sensor proportional ice load, and to a first input of both AND gates signals are generated via three summing elements emit difference of each block allocation signal amplitude output and input signals of the two summarizing the elements of these differences, booster elements and analog-to-digital converters. AND gates controlled installation deicing forming short pulses of current in one or the other wiring schemes depending on the wind direction, and provide a mechanical resonance oscillations wires until disappearance deicing and ice load.
