Description

Technical Field

[0001] The present application relates to the technical field of conductive rods, and in particular to a high-efficiency aluminum alloy conductor. Background Art

[0002] As the voltage and current levels of high-voltage transmission equipment continue to increase, high-voltage transmission equipment needs to withstand the combined effects of high voltage, large current and strong mechanical loads. There are high electrical, thermal and mechanical stresses inside it. High-voltage bushing is an important equipment commonly used in the high-voltage power industry. It includes an insulating sleeve and a conductive rod located inside the insulating sleeve. The conductive rod is used to connect the transformer coil lead wire to the external wire and is installed on the top of the transformer.

[0003] Chinese patent publication CN219738550U discloses a wear-resistant, oxidation-resistant aluminum conductive rod, specifically a mounting base. A rotating mechanism is fixedly mounted on the top surface of the mounting base, and a protective mechanism is fixedly mounted on the side of the rotating mechanism. The rotating mechanism includes a rotating portion, the bottom surface of which is fixedly connected to the top surface of the mounting base, and the rotating portion includes a rotating drum. The patent utilizes the mounting base and a fixing nut to enable installation of other devices and fix the mounting base. The installation of the rotating mechanism allows the terminal to rotate, further reducing the friction coefficient between the conductive rod and the rotating drum, thereby increasing the service life of the device.

[0004] However, in the above-mentioned patent, the terminal block can only rotate circumferentially but cannot move axially, which places high requirements on the design of the conductive rod. When the dimensions of the installation site are inconsistent with the design dimensions, the conductive rod cannot be reliably installed and a new conductive rod needs to be customized, which reduces the installation efficiency.

[0017] Below, the present application is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] like Figure 1-3 As shown, a high-efficiency aluminum alloy conductor includes a terminal block 1, a rod body 2 and a base 3 arranged in sequence from top to bottom. The base 3 is welded to the bottom of the rod body 2. A clamp 4 is provided at the bottom of the terminal block 1. The clamp 4 is sleeved on the outside of the rod body 2 and can be locked by a bolt. A threaded portion 20 is provided on the upper portion of the rod body 2. An adjusting nut 5 is adapted to be screwed onto the threaded portion 20. The adjusting nut 5 can move up and down at the threaded portion 20. The top of the adjusting nut 5 contacts the bottom of the clamp 4. The adjusting nut 5 is used to support the clamp 4.

[0019] When installing the conductor, the rod body 2 can be fixed by connecting the base 3 to the installation surface, and then the clamp 4 is placed on the outer wall of the rod body 2. At this time, the clamp 4 is in an untightened state, and the clamp 4 and the terminal 1 can slide up and down on the outside of the rod body 2. The position of the adjusting nut 5 can be adjusted by rotating the adjusting nut 5. Since the adjusting nut 5 is adapted to the threaded portion 20, the adjusting nut 5 is in a fixed state after the position adjustment is completed. The clamp 4 is then slid so that the clamp 4 contacts the adjusting nut 5, and the clamp 4 is tightened by the bolt to reliably connect the clamp 4 to the rod body 2. According to different installation size requirements, the adjusting nut 5 can be rotated to the corresponding position to adjust the position of the clamp 4 and the terminal 1. This can adapt to more complex installation requirements, save installation costs, and improve installation efficiency.

[0020] The minimum inner diameter of the clamp 4 is smaller than the outer diameter of the rod body 2, and the maximum inner diameter of the clamp 4 is larger than the outer diameter of the rod body 2. In this way, when the clamp 4 is not tightened, the clamp 4 and the terminal 1 can move up and down smoothly. When the clamp 4 is tightened, the clamp 4 can be reliably fixed, thereby fixing the position of the terminal 1.

[0021] Copper foil 6 is laid on the inner wall of the clamp 4, and the copper foil 6 wraps the outer wall of the rod body 2. There is no connection between the copper foil 6 and the rod body 2 or between the copper foil 6 and the clamp 4, and the length of the copper foil 6 is greater than the circumference of the rod body 2. It is only necessary to place the copper foil 6 between the inner wall of the clamp 4 and the outer wall of the rod body 2 before tightening the clamp 4. In this way, during the tightening process of the clamp 4, the copper foil 6 can fill the threads of the threaded part 20, which on the one hand plays a role in protecting the threaded part 20, and on the other hand can increase the friction between the clamp 4 and the rod body 2, thereby improving the fixing effect of the clamp 4 on the rod body 2.

[0022] The clamp 4 includes an arc portion 41 and two straight portions 42. One straight portion 42 is provided at the head end of the arc portion 41, and the other straight portion 42 is provided at the end of the arc portion 41. The arc portion 41 is arranged around the outside of the rod body 2. The two straight portions 42 are parallel to each other. The bolts are passed through the two straight portions 42. After the bolts are tightened, the two straight portions 42 are changed from a state of separation to a state of mutual contact, thereby realizing the tightening of the clamp 4.

[0023] A receiving groove 51 is provided at the top of the adjusting nut 5. The receiving groove 51 is connected end to end and is annular. The inner diameter of the groove 51 at the notch is smaller than the inner diameter of the groove bottom. A slider 52 is adapted to be provided in the receiving groove 51. The slider 52 can slide in the receiving groove 51. A fixing rod 53 is provided at the top of the slider 52. One end of the fixing rod 53 is connected to the slider 52, and the other end of the fixing rod 53 extends between the two straight portions 42. When the position of the adjusting nut 5 is adjusted, the position of the clamp 4 is also fixed. At the same time, the fixing rod 53 will be inserted between the two straight portions 42. At this time, after the two straight portions 42 are locked, the fixing rod 53 will be clamped by the two straight portions 42. Since the slider 52 is limited to slide only circumferentially in the groove and cannot move axially, it can effectively prevent the adjusting nut 5 from loosening, effectively improving the supporting effect of the adjusting nut 5 on the clamp 4.

[0024] A notch 54 is provided on the outer wall of the adjusting nut 5, and the notch 54 is connected to the receiving groove 51. The slider 52 and the fixing rod 53 slide into the receiving groove 51 through the notch 54. When the adjusting nut 5 is rotated, the slider 52 and the fixing rod 53 can be taken out of the receiving groove 51 to prevent interference between the fixing rod 53 and the clamp 4. When the positions of the adjusting nut 5 and the clamp 4 are adjusted, the slider 52 and the fixing rod 53 can be placed into the slide groove through the notch 54, and the fixing rod 53 can be slid between the two straight portions 42. The above embodiment is only a preferred embodiment of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and replacements made by those skilled in the art on the basis of the present application fall within the scope of protection claimed by the present application.
