Problems solved by technology

[0008] These existing research results are of great significance to the deicing of transmission lines, but these studies only focus on "deicing after icing", and there is no relevant research on how to prevent transmission lines from icing. Research

Embodiment Construction

[0046] Such as Figure 1 to Figure 8 As shown, the power supply line anti-icing transformation method of the present invention is carried out using a special transformation device. The special transformation device includes a lifting truck 21. The chassis 22 of the lifting truck 21 is provided with a lifting operation part, and the lifting operation part includes a rotating connection. On the support frame 23 on the chassis 22, the support frame 23 is provided with a hoist 24 and a support platform 25, and the support platform 25 is hinged with a telescopic boom 26, and a fixed pulley assembly 27 is installed at the end (ie the upper end) of the telescopic boom 26; 24 is connected with hoisting wire rope 28, and hoisting wire rope 28 upwards walks around fixed pulley assembly 27 and is connected with movable pulley assembly 29 downwards, and movable pulley assembly 29 is suspended with operation bucket 30 by suspension rope downwards, is provided with anti-corrosion block in op...

Abstract

The invention discloses a power supply line anti-freeze reconstruction method comprising the following steps in sequence: 1, forenotice; 2, preparation; 3, starting up; 4, lifting: controlling a hoist to lift a working bucket up to a constructed power supply line; 5, working process; 6, ending; when the constructed power supply line section is filled with anti-freeze covers, the step 5 is stopped, the ground personnel controls the hoist to lower the working bucket, restores the power supply line power supply, and withdraws workers and materials. The power supply line anti-freeze reconstruction method is simple in steps, can conveniently modify the existing power supply line into a passive mode anti-freeze power supply line, so ices and snows cannot attach and accumulate on the anti-freeze covers, thus providing active anti-freeze effect; the working bucket position can be adjusted along the power supply line, so the work personnel can always work in the front side.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to an anti-icing power transmission line. Background technique [0002] The normal operation of modern society is inseparable from the normal supply of electricity. In winter, due to the low temperature, under weather conditions such as rain and snow, icing is prone to occur on transmission lines. Transmission lines, especially high-voltage transmission lines, have long power supply distances and large transmission capacity. Once a failure occurs, it will cause huge economic losses to downstream power consumers and individuals. For example, in 2005, a 500KV ultra-high voltage transmission line in Central China Power Grid suffered a tower collapse and disconnection accident, which caused economic losses of more than 10 million yuan to downstream power consumers. After investigation, the main cause of the accident was that the icing thickness of the transmission line exceeded t...
