Description

Technical Field

[0001] The invention relates to the technical field of power transmission lines, in particular to a temporary current diversion device for power transmission lines. Background Art

[0002] The benefit of temporary connection of transmission lines is to ensure smooth circuit in emergency situations. The current connection principle is to use a conductor clamp to process the outer layer of the broken surface of the conductor to expose the inner core, and then clamp and fix the broken surface of the conductor through the conductor clamp to achieve connection and conduction. At present, the conductor core is mainly clamped and fixed in the form of a screw push block, and the conductor core is fixed by the force of the push block. This method is mainly affected by two collinear radial forces and is limited by an arc surface. This method is unstable.

[0003] At the same time, during use, the connection nodes will generate heat. When abnormally high temperatures occur, the heating problem cannot be accurately detected by visual inspection. Potential overheating problems may be signals of short circuits, poor contact or environmental changes. The inability to obtain temperature will increase the possibility of accidents. Summary of the invention

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1, reference Figures 1 to 6 , which is the first embodiment of the present invention, provides a temporary diversion device for a power transmission line, comprising:

[0035] The support body 100 has a first space 101 and a second space 102 therein; the first space 101 and the second space 102 are respectively used to place the wire ends to be connected.

[0036] The fixing member 200 is disposed in the first space 101 and the second space 102 and is used to fix the wire. The wire can be fixed by squeezing the wire through the fixing member 200.

[0037] The limiting member 300 includes a side sealing portion 301 rotatably disposed on the supporting body 100 , and a fitting portion 302 disposed on the side sealing portion 301 .

[0038] When in use, the wire ends are placed in the first space 101 and the second space 102, and then the wires are squeezed and fixed by the fixing member 200. When squeezed and fixed, the wires press the fitting part 302, which will cause the limiting member 300 to rotate, and then the side sealing part 301 will close the side of the second space 102, thereby improving the fixing effect and the wire anti-falling effect.

[0039] Specifically, the support body 100 is in an I-shaped structure; the first space 101 and the second space 102 are respectively disposed at two openings of the I-shaped structure.

[0040] Fixing members 200 are disposed in both the first space 101 and the second space 102 , and the two wire ends can be fixed respectively by disposing the fixing members 200 .

[0041] Furthermore, a screw 201 is rotatably provided on the fixing member 200, and the screw 201 is arranged through the support body 100. The screw 201 and the support body 100 are threadedly connected. By rotating the screw 201, the fixing member 200 can be pushed to move, and the wires inserted into the first space 101 and the second space 102 can be clamped and fixed.

[0042] Among them, a first arc-shaped surface is provided in the first space 101; the provision of the first arc-shaped surface facilitates the fitting of the wire end and the inner wall of the first space 101, thereby improving the fixing effect and the contact area, and increasing the conductive effect.

[0043] A second arc surface is provided in the second space 102 . The second arc surface facilitates the fitting of the wire end to the inner wall of the second space 102 , thereby improving the fixing effect and the contact area, and increasing the conductive effect.

[0044] Preferably, the limiting member 300 further includes a limiting block 303 disposed on the fitting portion 302 .

[0045] It should be noted that when the clamping period of the wire core is long, the wire core and the second curved surface in the second space 102 are affected by the force, making it impossible for the wire core to be easily removed from the second curved surface, and pulling the wire core will easily cause the wire core to rub against the second curved surface. Therefore, the limit block 303 is moved to assist the fitting part 302 to rotate, so that the wire core can be vertically removed from the second curved surface in the second space 102 to avoid friction that may cause damage to the wire core.

[0046] It should be noted that a limit member 300 can be set at both the first space 101 and the second space 102 to facilitate better separation of the wires. However, during normal docking, only one side often needs to be separated. Therefore, generally, it is only necessary to set a limit member 300 on one side of the first space 101 or the second space 102.

[0047] Example 2, reference Figure 1 to Figure 6 , which is the second embodiment of the present invention, and is different from the previous embodiment in that a placement groove 104 is provided on the support body 100;

[0048] A support shaft 301 a is provided in the placement groove 104 , and the position limiting member 300 is rotatably connected to the support body 100 via the support shaft 301 a , and the support body 100 and the side sealing portion 301 are connected via the support shaft 301 a , so as to facilitate the rotation of the position limiting member 300 .

[0049] Specifically, a conductive body 400 is provided in the support body 100; the conductive body 400 can be used for current conduction, therefore, the support body 100 can be made of non-conductive material to improve the insulation effect and further improve the safety of the connection. It should be noted that the conductive body 400 is designed in an S-shaped structure, and the conductive body 400 fits the first curved surface and the second curved surface, so that the conductive body 400 and the wire end are fitted and connected to conduct current. At the same time, the overall material can be selected from non-conductive materials to avoid the overall heating problem.

[0050] Furthermore, a temperature acquisition module 500 is provided in the support body 100. In the present embodiment, the temperature acquisition module 500 is used to collect the temperature of the conductor 400. The temperature acquisition module 500 includes a surface mount temperature sensor and a wireless data transmission unit. The wireless data transmission unit detects the heating problem of the conductor 400 using the surface mount temperature sensor, and transmits the information to the monitoring terminal for monitoring, so as to facilitate the detection of the temperature of the connection part and improve the safety during use.

[0051] A torsion spring is provided between the support shaft 301a and the stopper 300. By providing the torsion spring, the side seal portion 301 can be in a tilted state when the wire is not installed. Figure 1 In this state, it is easy to insert the wire end and the operator can place the wire conveniently.

[0052] The fitting portion 302 is designed to be arc-shaped, and the fitting effect of the fitting portion 302 can be improved through the arc-shaped structural design.

[0053] The rest of the structure is the same as that of Example 1.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
