Description

Technical Field

[0001] The utility model relates to the technical field of power connection accessories, in particular to an overhead conductor drain wire connection device. Background Art

[0002] At present, the T-connection position of the conductor drainage line of the overhead line tower usually adopts a parallel groove wire clamp or a bolt-type T-type wire clamp. These methods rely on the tightening force of the bolt to enable the wire clamp to connect the branch line conductor with the main line conductor.

[0003] However, since most transmission lines are located in the wild, on mountain tops, at wind outlets and in micro-topography areas, the lines are subject to wind all year round, and the temperature difference between winter and summer causes the conductor sag to change, causing the T-connection to alternate between bending and straightening in winter and summer. The parallel groove clamp and the bolted T-type clamp are prone to repeated shaking at the exit, causing the bolts to loosen, causing the temperature of the connection between the conductor and the clamp to rise, and it is easy to wear, slide, and fatigue fracture, resulting in line accidents, and low reliability. In addition, the existing parallel groove clamp and bolted T-type clamp cannot achieve full contact with the conductor, resulting in a large contact resistance and increased power loss.

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Combine the following Figures 1 to 8 The utility model describes an overhead conductor drain wire connecting device.

[0032] like Figures 1 to 8 As shown, the embodiment of the utility model provides an overhead conductor drain line connection device, which is suitable for the conductor drain line position of the overhead line tower. Specifically, Figure 1 As shown, the overhead conductor drain wire connection device includes a wire clamp body 1 and at least one drain wire clamp 2. Generally, the wire clamp body 1 and the drain wire clamp 2 are both made of aluminum. Figure 2 As shown, the wire clamp body 1 includes a first connection part 11 and a pair of first hydraulic terminal blocks 12. Specifically, the first connection part 11 and the pair of first hydraulic terminal blocks 12 are an integrated molding structure, which is easy to process and manufacture, and has high structural strength. A pair of first hydraulic terminal blocks 12 are respectively arranged at the two ends of the first connection part 11, and a pair of first hydraulic terminal blocks 12 are provided with a first wire pressing hole 13 arranged along its axial direction. When connecting, a hydraulic press is used to press the main line direction conductors into the first wire pressing holes 13 at both ends for hydraulic fixation. The wire is pressed and fixed by hydraulic means, which is stable and reliable. Moreover, since the wire is usually steel core aluminum stranded wire or aluminum clad steel core aluminum stranded wire, the wire clamp and the wire cannot achieve 100% area contact when the traditional bolts are used for compression and fixing. The use of hydraulic connection can greatly increase the contact area between the wire and the wire pressing hole, thereby reducing the contact resistance, which is beneficial to power transmission.

[0033] like Figure 6As shown, the drainage clamp 2 includes a second connection portion 21 and a second hydraulic terminal 22. Specifically, the second connection portion 21 and the second hydraulic terminal 22 are an integrally formed structure, which is convenient for processing and manufacturing, and has a high structural strength. The second hydraulic terminal 22 is arranged at one end of the second connection portion 21, and the second hydraulic terminal 22 is provided with a second wire pressing hole 23 arranged along its axial direction. When connecting, a hydraulic press is used to press the branch direction wire into the second wire pressing hole 23 for hydraulic fixation. And, as shown in FIG. Figure 1 As shown, the second connection part 21 is connected to the first connection part 11, thereby connecting the main line direction wire and the branch direction wire to achieve circuit conduction. Figure 1 and Figure 2 As for the placement position of the overhead conductor drainage line connection device shown in the figure, the direction indicated by the solid arrow in the figure is the main line direction, the axial direction of the first hydraulic terminal 12, and the direction indicated by the hollow arrow in the figure is the branch direction, the axial direction of the second hydraulic terminal 22.

[0034] With such a configuration, the first connection part 11 and the second connection part 21 are connected during installation, and the main line direction conductor is hydraulically connected to the first wire pressing holes 13 at both ends of the first connection part 11, and the branch direction conductor is hydraulically connected to the second wire pressing holes 23 at the end of the second connection part 21, so as to realize the connection and conduction between the main line and the branch line. Thus, the conductor is fixed by hydraulic connection, instead of the method of fastening the conductor to the wire clamp with bolts, eliminating the problems of easy heating, loosening, friction, and breakage caused by the traditional bolt fastening force, and the connection is stable and reliable, and it is safer to use. And the hydraulic connection method can make the conductor fully contact with the wire pressing hole, reduce the contact resistance, and reduce the power loss.

[0035] In addition, it should be noted that the specifications of the two first crimping holes 13 and the second crimping holes 23 can be specifically determined according to actual usage requirements. They can be designed to be the same specifications or different specifications to be suitable for wires of different cross-sectional sizes. The scope of application is relatively wide, especially for the reconstruction of old lines when connecting wire sections of different specifications, the advantages are more prominent.

[0036] Furthermore, in the embodiment of the utility model, the first connection part 11 and the second connection part 21 are respectively provided with at least one connection hole 4 for inserting the fastener 3. Specifically, the fastener 3 can be a bolt. In this way, the first connection part 11 and the second connection part 21 are connected by bolts, so as to realize the quick connection of the wire clamp body 1 and the drainage wire clamp 2, which is convenient for assembly and operation, and improves the efficiency of line installation. Of course, in other embodiments, the first connection part 11 and the second connection part 21 can also be connected by welding, bonding or riveting.

[0037] In some embodiments of the present invention, Figure 1As shown, the drain wire clamp 2 is one, which is connected to the wire clamp body 1 to form a three-way overhead wire drain wire hydraulic T-connection device. Compared with the existing overhead wire drain wire T-connection using parallel groove wire clamps or T-connection clamps, it has higher reliability, is safer and more stable, and has less power loss. At the same time, Figure 1 As shown, there are at least two connection holes 4, and each connection hole 4 is arranged at intervals along the axial direction of the second hydraulic terminal 22. This ensures that the wire clamp body 1 and the drainage wire clamp 2 are firmly connected to achieve reliable power transmission. Specifically, the wire clamp body 1 can be designed as a symmetrical structure, and there can be two connection holes 4.

[0038] In other embodiments of the present invention, Figure 3 As shown, the drainage clamps 2 are a pair, and the pair of drainage clamps 2 are arranged in sequence along the axial direction of the first hydraulic terminal 12, so as to be connected with the clamp body 1, forming a four-way overhead conductor drainage line hydraulic T-connection device. Compared with the existing overhead conductor drainage line T-connection using parallel groove clamps or T-connection clamps, it has higher reliability, is safer and more stable, has less power loss, and the four-way structure is more flexible for T-connected two-circuit lines.

[0039] At the same time, if Figure 5 As shown, there are two groups of connection holes 4, and the two groups of connection holes 4 are arranged corresponding to a pair of drainage wire clamps 2. Each group of connection holes 4 has at least two, and each group of connection holes 4 is arranged at intervals along the axial direction of the second hydraulic terminal 22. This ensures that the wire clamp body 1 and the pair of drainage wire clamps 2 are stably connected to achieve reliable power transmission. It should be noted that, as shown in FIG. Figure 3 and Figure 5 As for the placement position of the overhead conductor drainage line connection device shown in the figure, the direction indicated by the solid arrow in the figure is the main line direction, the axial direction of the first hydraulic terminal 12, and the direction indicated by the hollow arrow in the figure is the branch direction, the axial direction of the second hydraulic terminal 22.

[0040] In some embodiments of the present invention, Figure 3 As shown, a pair of drain wire clamps 2 are arranged on the same side of the first connecting portion 11. In this way, two drain wire clamps 2 of the four-way type can be arranged in the same direction, which is convenient for T-connecting two circuits on the same side.

[0041] In some other embodiments of the present invention, Figure 4 As shown, a pair of drain wire clamps 2 are respectively arranged on both sides of the first connecting portion 11. In this way, the two drain wire clamps 2 of the four-way type can be arranged up and down in reverse, which is convenient for reverse T-connection of two circuits. Figure 4 As for the placement position of the overhead conductor drainage line connection device shown in the figure, the direction indicated by the solid arrow in the figure is the up and down direction, the main line direction, and the axial direction of the first hydraulic terminal 12, and the direction indicated by the empty arrow in the figure is the branch direction and the axial direction of the second hydraulic terminal 22.

[0042] In an optional embodiment of the present utility model, as Figure 7 As shown, the axial direction of the second connection portion 21 is parallel to the axial direction of the second hydraulic terminal 22. In other words, the drainage clamp 2 is a linear structure, which is easy to manufacture and can meet the installation requirements of the wire.

[0043] In an optional embodiment of the present utility model, as Figure 8 As shown, the axial direction of the second connection part 21 and the axial direction of the second hydraulic terminal 22 are arranged at an angle a. It should be noted that the size of the angle a needs to be specifically determined according to actual design requirements. In this way, the drainage clamp 2 has a bent structure, which can adapt to different T-connection angles, reduce the bending degree of the wire, and ensure that the wire has a sufficient safe distance from the tower body.

[0044] In a specific embodiment of the utility model, the connection surface of the first connection part 11 and the second connection part 21 is a plane. In this way, the bolt passes through the wire clamp body 1 and the drainage wire clamp 2 in sequence, and is fastened with a gasket and a nut, so that the wire clamp body 1 and the drainage wire clamp 2 are reliably in contact, the connection is stable, and it is easy to assemble. In addition, in order to extend the service life of the device, the surface of the bolt needs to be rust-proofed, such as using a hot-dip galvanizing surface treatment process.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
