Abstract
Способ определения длины и толщины гололеда на проводах линии электропередачи, включающий передачу по проводам линии электропередачи высокочастотного сигнала от передающего устройства к приемному устройству, и контроль параметров, связанных с изменением условий распространения высокочастотного сигнала по участку провода между передающим и приемным устройствами при появлении гололеда, в качестве контрольных параметров принимают время распространения высокочастотного сигнала от передающего устройства к приемному устройству, и амплитуду высокочастотного сигнала, принимаемого приемным устройством, определяют среднее значение температуры этого участка провода, а о длине и толщине гололеда на проводах линии электропередачи судят по изменению времени распространения высокочастотного сигнала и по изменению амплитуды высокочастотного сигнала, вызванных появлением гололеда, с учетом влияния на контролируемый параметр температурного изменения длины участка провода, отличающийся тем, что по радиоканалу или по оптоволоконному кабелю передают синхросигнал от передающего устройства к приемному устройству, при этом данный синхросигнал используют для определения времени распространения высокочастотного сигнала от передающего устройства к приемному устройству.A method for determining the length and thickness of ice on wires of a power line, comprising transmitting a high-frequency signal from a transmitting device to a receiving device by wire of a power line, and monitoring parameters associated with changing conditions for the propagation of a high-frequency signal along a portion of the wire between the transmitting and receiving devices when ice appears as control parameters take the propagation time of the high-frequency signal from the transmitting device to the receiving device, and amp the mass of the high-frequency signal received by the receiving device determines the average temperature of this section of the wire, and the length and thickness of ice on the wires of the power line are judged by the change in the propagation time of the high-frequency signal and the change in the amplitude of the high-frequency signal caused by the appearance of ice, taking into account the effect on the controlled parameter temperature change of the length of the wire, characterized in that the radio channel or fiber optic cable transmit the clock signal from the present device to the reception device, wherein the clock signal is used to determine the propagation time of the high-frequency signal from the transmitter to the receiver.
