Abstract
The purpose of the research is to develop a device for remote monitoring of the characteristics of ice-and-cloud-bearing deposits on a TL wire based on the use of ultrasonic testing technologies that is devoid of the above-mentioned shortcomings. Results of researches of possibilities of application of technologies of the ultrasonic control for remote monitoring of characteristics of ice-frost deposits on wires of overhead power lines are given. The use of ultrasonic thickness sensors is proposed, which are fixed directly to the surface of the monitored line element, which makes it possible to reduce the degree of influence of the structural elements of the device on the conditions for the formation of ice-frost deposits in control points, to increase the accuracy of determining the deposition thickness in the conditions of dancing, the vibrations of the controlled element, control the thickness of deposits in several radial directions and, as a result, improve the quality and Qualitative indicators of the received information. As an example of implementation, an apparatus for remote monitoring of the characteristics of ice-frost deposits on an air line wire is described which is equipped with four ultrasonic deposition thickness sensors and four pairs of "emitter-receiver" for determining the propagation velocity of ultrasound in the deposition. The principle of operation of the device is justified. It is determined that the data received from the device allows the personnel of electrical networks to monitor the occurrence and disappearance of ice-frost deposits, its shape, size and density, which will provide a more accurate determination of the necessary parameters of the melting mode of deposits and, as a consequence, will reduce the number of ineffective meltings.
