Deicing and anti-freezing system during transportation of electric transmission line

Abstract

The invention provides a deicing and anti-freezing system during the transportation of an electric transmission line. The deicing and anti-freezing system during the transportation of the electric transmission line is capable of deicing and anti-freezing for a wire and an insulator by utilizing the electric energy of the owned line or the additional electric energy when the operation of the electric transmission line is normal. The electric transmission line deicing and anti-freezing system includes that a split-type electric transmission sub-line is divided into one section or a plurality of sections. Each in-phase divided conductor breakover is connected and a divided conductor pair is formed at a junction position or an endpoint of the adjacent wire sections. The electric transmission line deicing and anti-freezing system includes a hollow structure where the insulator is provided with an air inlet and an air outlet in a top- and-bottom mode. The hot gas generated from an electric steam generator which is arranged on the transmission line tower enters through the air inlet of the insulator and flows out from the air outlet so that the insulator generates heating for deicing and anti-freezing. The deicing and anti-freezing working range of the insulator is in the same section with wire deicing, and the deicing anti-freezing power source of the insulator is the same power source with the wire deicing anti-freezing power source.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a deicing and antifreezing system for conductors in transit and an insulator in transit for deicing and antifreezing systems in power transmission lines. Background technique [0002] At present, most of the transmission lines in the world, especially ultra-high voltage lines, are overhead. However, when the overhead transmission line encounters a special ice and snow disaster, the ice and snow will seriously wrap the wires and insulators and damage the line or make the line short-circuited and unable to operate, which will bring huge or even devastating damage to the power grid. [0003] In order to deal with the occurrence of the above-mentioned disasters, traditional deicing methods include the following methods: [0004] 1) Use manual or mechanical methods to de-ice the wires. This method is not only extremely inefficient and easy to damage the circuit, but also must be carried...

Problems solved by technology

Although this kind of mode is feasible on the line with less capacity and shorter lines, it has the following disadvantages: (A) the deicing line must be powered off, which will have a great impact on people's production and life; (B) For large-capacity and long-distance transmission lines, it is difficult to use this method to deice

[0006] For ultra-high voltage lines, even if the ice and snow on the conductors are removed, the ice and snow on the insulators may still short-circuit the lines and fail to operate.
