Problems solved by technology

Once the icing load of the power conductor is too heavy and the sag of the line increases, the grounding short circuit of the transmission conductor will occur, causing the line to trip. Severe icing will cause the transmission tower to twist and collapse

Embodiment 1

[0023] As shown in the figure, it is a structural schematic diagram of the coating equipment used in the coating method of the anti-ice and snow layer of the wire, including the front positioning mold 1, the spraying box 2, the sizing mold 3, and the rear positioning mold 4, which are arranged in sequence with the same center height And drying box 5, spraying box 2 is connected on the total storage box 6 by booster pump through pressure-resistant pipeline; It also includes storage tank No. 1 and No. No. storage box 62, a mixing box 64 with a stirrer for storing the C mixture, and a metering pound 63 connecting the No. 1 storage box 61, the No. 1 storage box 62 and the mixing box 64, the No. 1 storage box 61, the No. 2 storage box 62 communicates with mixing tank 64 through weighing scale 63, and mixing tank 64 communicates with total storage tank 6.

Embodiment 2

[0029] Embodiment 2: The anti-icing and snow coating equipment is placed between the stranding mold 8 and the traction wheel 9 of the stranding cage in the last section of the stranding machine.

[0030] (1) Spray a liquid waterproof paint on the surface of the wire to form a coating layer.

[0031] Assuming that a 0.1mm thick coating layer needs to be obtained, after the wires with a diameter of 20mm are twisted and formed, under the action of the front positioning mold 1 and the rear positioning mold 4 with the front and rear apertures of 20.4mm, the front positioning mold 1 and the rear positioning mold 4 are ensured at the same time. The height of the hole center of the positioning die 4 is consistent with the center height of the stranding unit, so that when the wire is continuously twisted and manufactured, it is kept running at the center height of the entire unit; the wire passes through the front positioning die 1 and enters the spraying box 2 for pressure spraying, sp...

Abstract

The invention discloses a method for coating wire with ice-snow prevention layers. The method comprises the following steps of spraying waterproof paint on the surface of the wires to form a coating layer, regulating the coating layer on the surface of the wire to enable the coating layer to reach the set thickness, and drying the coating layer of the wire at a temperature between 50 and 70 DEG C. The invention also discloses a coating device of the method. Because the invention adopts pressure coating, gaps among aluminum strands on the outermost layer of the wire can be filled up; through the adjustment of a diameter-setting mold, the coating layer is not only uniform in the surface, but also controllable in thickness, so the whole coated wire is smooth and compact in the surface, and snow or frozen rain is not easy to solidify on the surface of the wire; and a steel wire on a center layer of the wire is not easy to pollute by rainwater or corrosive atmosphere. Therefore, the wire not only has the characteristics of preventing ice and snow and resisting corrosion, but also has the advantages of reducing the vibrating and waving harm of breeze, lowering the level of corona and radio interference and enabling power transmission lines to be lower in noise hazard and friendlier to environment.

Description

technical field [0001] The invention relates to a method for coating a wire anti-ice and snow layer for power transmission lines, and also relates to coating equipment used in the coating method. Background technique [0002] Electricity is an indispensable and important energy source for the development of the national economy. With the sustained and rapid development of my country's national economy, the demand for electricity has risen sharply, and the transmission lines that were already operating at full capacity are even more overwhelmed. Coupled with the large-scale damage to power lines caused by natural disasters, the original tight power supply situation is even worse. In order to solve this imminent contradiction, my country has used more than 1 million tons of overhead transmission lines every year in recent years. Different forms of products, Provided to the market to meet market demand. [0003] With the continuous strengthening of my country's transmission net...
