Embodiment Construction

[0023] An auxiliary scale device for observation of icing on transmission lines, including a scale and a controller installed on the transmission line under test, such as figure 1 As shown, the scale includes a hoop 1 in the middle, and 4 LED scales 2 evenly installed on the outer periphery of the hoop 1. The hoop 1 includes 2 semicircular rings 11, 2 One end of the semi-circular ring 11 is flexibly connected by a peg, and the other end is fixedly connected by a bolt. Rubber pads 12 are provided on the inner walls of the two semicircular rings 11 that are in contact with the transmission line under test. Through the rubber pads 12, the combination of the hoop 1 and the transmission line under test can be made firmer without damaging the transmission line. better. The connecting end of the LED scale 2 and the hoop 1 is provided with a reinforcing plate 27, and the setting of the reinforcing plate 27 can make the connection between the LED scale 2 and the outer wall of the semi...

Abstract

The invention discloses an auxiliary scale apparatus used for ice coating observation of a power transmission line. The apparatus comprises a scale and a controller, the scale comprises a hoop and at least two LED calibrated scales uniformly arranged at the periphery of the hoop, the LED calibrated scales are provided with a plurality of LED lamps along the radial direction of a detected power transmission line, the ice coating thickness of the detected power transmission line is indicated through the LED lamps, a temperature sensor and a heating strip are arranged in each calibrated scale, and the controller is connected with the LED lamps, the temperature sensors and the heating strips. The auxiliary scale apparatus used for ice coating observation of the power transmission line serves as an additional apparatus for video ice coating observation, the problem of inaccurate estimation of the ice coating thickness by a video method is solved, the ice coating observation auxiliary scale can help observation personnel to determine the current ice coating thickness more conveniently and accurately through the scale, and the error between the observed ice coating thickness value and the practical ice coating thickness value is greatly reduced.

Description

technical field [0001] The invention relates to an auxiliary scale device for the observation of icing on transmission lines, which belongs to the field of on-line monitoring of transmission lines. Background technique [0002] Severe icing of transmission lines will bring a series of ice disasters, such as ice flash of insulator strings, disconnection of ground wires, toppling of towers, etc., which seriously threatens the safe operation of the power system and will cause major economic losses. loss and social impact. [0003] The video observation method is one of the real-time monitoring methods for line icing. By installing cameras on the poles and towers along the line, the icing conditions of conductors, insulators, pole towers, and line corridors are regularly monitored. The observation is intuitive and convenient, and the series of conductors and insulators can be observed in real time. Conditions of ice formation and development, and severity of icing. However, wh...
