Embodiment Construction

[0021] An auxiliary scale for the observation of icing on transmission lines, including a scale for installation 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-circular rin...

Abstract

The invention discloses an auxiliary scale for observing icing of a power transmission line. The auxiliary scale comprises a hoop, and at least two LED calibrated scales uniformly arranged on the periphery of the hoop, and a plurality of LED lamps are arranged on the LED calibrated scales along the radial direction of a power transmission line to be detected. The LED lamps indicate the thickness of ice on the power transmission line to be detected, and a temperature sensor and a heating strip are arranged in the calibrated scales. The auxiliary scale is used as an additional device for video icing observation, and solves the problem that icing thickness observation and estimation is inaccurate through a video frequency method. The auxiliary scale helps observers to more conveniently and accurately determine icing thickness, and greatly reduces difference between the observed icing thickness value and the actual icing thickness value.

Description

technical field [0001] The invention relates to an auxiliary scale used 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, when...
