Description

Technical Field

[0001] The utility model relates to the technical field of overhead lines, in particular to a low wind resistance overhead line. Background Art

[0002] Long-distance power transmission usually encounters rivers, railways, highways, straits and special facilities. In this case, large-span technology will usually be used. The longer the span, the greater the technical difficulty. Large-span overhead lines have large operating tension and are very easy to absorb natural wind energy. After being stimulated, they are also very likely to cause vibration or dancing of the overhead lines and other movements that damage the lines. The more intense the vibration and dancing, the greater the destructiveness to the line. Therefore, using a low-wind resistance overhead line can effectively reduce the impact of wind.

[0003] Existing technologies such as publication number CN216489669U disclose a vibration-proof device for overhead lines with ultra-large operating tension. The patent adopts an overhead line, and the overhead line is formed with a damping line with a wavy structure through a wire clamp. The overhead line is provided with a shock-proof hammer that matches the damping line. It is characterized in that the overhead line is also provided with a vibration-damping ball that matches the shock-proof hammer. The vibration-damping ball and the shock-damping hammer are both arranged at corresponding positions in the center of the wavy structure of the damping line, and the shock-damping hammer and the vibration-damping ball are arranged alternately. The device of the utility model solves the problem that although the existing technology adopts a vibration-proof device combining a shock-proof hammer and a damping line to avoid the occurrence of line fatigue fracture accidents, the energy absorption efficiency and capacity of this vibration-damping method are low, and the absorbed energy cannot be utilized, resulting in energy waste.

[0004] In daily work, when equipment is used to install overhead lines, the existing overhead lines transmit electricity at high altitudes for a long time. When used at high altitudes, the wind is strong at high altitudes, which can easily cause wind resistance to the overhead lines. The overhead lines can easily swing due to the wind resistance, causing friction damage at the connection between the overhead lines and the power racks, resulting in a decrease in the durability of the overhead lines. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcoming in the prior art that overhead lines are easily damaged by wind, and to propose a low wind resistance overhead line.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a low wind resistance overhead line, comprising an outer insulating layer, a conductor and an outer shell, the outer shell is arranged on the surface of the outer insulating layer, the conductor is arranged inside the outer insulating layer, the surface of the outer shell is provided with a wind resistance device, the wind resistance device comprises a wind-breaking block and a protective layer, the wind-breaking block is fixedly connected to both sides of the outer shell, the protective layer is fixedly connected inside the outer shell, the inside of the protective layer is fixedly connected with a connecting layer, and the connecting layer is fixedly connected to the surface of the outer insulating layer.

[0007] Furthermore, an air guide groove is provided on the surface of the shell. By providing the air guide groove, the wind direction can be guided, thereby reducing the situation where the wind direction is difficult to guide when the device is in use, causing the wind direction to blow randomly and making it difficult to reduce the wind resistance of the device.

[0008] Furthermore, a first air inlet hole is provided on the surface of the shell, and a second air inlet hole is provided on the side of the first air inlet hole. The first air inlet hole and the second air inlet hole can guide the wind to pass through the shell, thereby making the shell more firmly positioned.

[0009] Furthermore, a counterweight is fixedly connected to the lower surface of the shell. The counterweight can be provided to provide preliminary guidance for the shell and perform vertical positioning.

[0010] Furthermore, an auxiliary component is provided on the surface of the conductor, and the auxiliary component includes a protective cover and a rubber layer. The protective cover is fixedly connected to the surface of the conductor, and the rubber layer is fixedly connected to the surface of the protective cover. An outer winding core is provided inside the rubber layer.

[0011] Furthermore, the surface of the rubber layer (52) is fixedly connected to the shielding layer (51), and the surface of the shielding layer (51) is fixedly connected to the inside of the external insulating layer (1).

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] In the utility model, by setting the wind resistance device and the auxiliary component, when the device is in use, the user sets the shell through the surface of the connecting layer and the external insulating layer, and then when the device is installed and put into operation, the counterweight block is affected by its own gravity to orient the shell, and the wind-breaking block is opposite to the direction of the wind flow. Then when the wind blows, the wind is divided into upper and lower sides by the wind-breaking block, and then the wind is guided by the wind guide groove on the surface of the shell, and then the wind circulates through the first air induction hole and the second air induction hole, which has the effect of making the shell start more stable. By setting the wind resistance device and the auxiliary component, the wind resistance of the overhead line is effectively reduced, which plays a role in reducing the wind resistance of the overhead line and reducing the use of the device. Since the overhead line transmits electricity at high altitude for a long time, when it is used at high altitude, the wind force at high altitude is large, which is easy to cause wind resistance to the overhead line, and the overhead line is easy to swing due to the wind resistance, causing friction damage at the connection between the overhead line and the power rack, resulting in a decrease in the durability of the overhead line. The wind resistance device can reduce the wind resistance of the overhead line, and the auxiliary component can better protect the conductor inside the overhead line, thereby improving the practicality of the device.
