Method and equipment for processing honed conductor

Abstract

The invention discloses a method and equipment for processing a honed conductor. The method comprises the following steps of: making the conductor pass through a sandblasting box at a constant speed, and uniformly spraying sand grains on the surface of the conductor by utilizing a spray gun to form a honed effect. In the equipment, a centrifugal chamber is arranged on the upper side of the sandblasting box; the lower end of the centrifugal chamber is connected with a sand guide pipe, and the upper end of the centrifugal chamber is connected with a sand storage chamber; a high-pressure air pipe is connected with a high-pressure air source; a plurality of groups of spray guns are annularly arranged at the periphery of the conductor; each spray gun is provided with two inlets; and one inlet is connected with the high-pressure air pipe, and the other inlet is connected with the sand guide pipe. In the invention, a continuous, dense and uniform honed layer is formed on the surface of the conventional overhead conductor through a sandblasting process, and mechanical strength, electrical conductivity and surface quality of the conductor cannot be influenced. Mirror reflection on the surface of the conductor is eliminated through the honed layer, and a diffuse reflection coefficient does not exceed 32 percent; moreover, a passivation effect can be achieved.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a method for processing matte wires and special equipment thereof. Background technique [0002] Aerial conductors are widely used in transmission lines due to their excellent mechanical properties and electrical conductivity. The surfaces of the overhead wires in the prior art are all very bright, forming specular reflections, causing light pollution, and posing potential safety hazards. With the surge of power transmission capacity, the coverage of power grids and lines is denser, and the impact of light pollution on densely populated areas and light-sensitive places cannot be ignored. For example, the overhead wires laid near the airport will affect the pilot's sight when the light is strong, which will pose a serious threat to aviation safety, especially the opening of low-altitude areas. At the same time, the safety of overhead transmission lines is related to people's live...

Problems solved by technology

Chemical corrosion, electric corrosion and increasing the surface coating are the methods to achieve the matte performance of wires, but chemical corrosion, electric corrosion and other methods are not conducive to continuous operation, reduce production efficiency and pollute the environment, and will cause the surface of the internal conductor of the wire to be rough

Once the surface of the conductor is not smooth, it is easy to cause the concentration of the local electric field, causing tip discharge or corona, resulting in the local temperature of the conductor being too high during use, causing a decline in electrical and mechanical properties, and even causing the conductor to break in severe cases.

Increasing the surface coating will increase the production cost, and the use of chemical coating will also cause environmental pollution
