Description

Technical Field

[0001] This utility model relates to the field of power fittings technology, and in particular to a GIS aluminum alloy conductor. Background Technology

[0002] Gas-insulated metal-enclosed switchgear, or GIS for short, is an important power transmission and distribution equipment. GIS consists of circuit breakers, disconnecting switches, grounding switches, instrument transformers, surge arresters, busbars, connectors, and outgoing terminals. All of these devices or components are enclosed in a metal-grounded enclosure, which is filled with SF6 insulating gas at a certain pressure.

[0003] Existing Chinese patent documents disclose a non-circular conductor for GIS disconnect switches, comprising a non-circular conductor body with a first connecting end, a second connecting end, a third connecting end, and a fourth connecting end. The first and second connecting ends are horizontally arranged, and their central axes coincide. The third and fourth connecting ends are vertically arranged, and their central axes are parallel but not coincident. When applied inside a GIS disconnect switch, the conductor allows current flow in four connection directions. Within the enclosed housing, the conductor joint can connect to either a shield or a current-carrying conductor. The first and second connecting ends satisfy a linear current flow pattern, and any one of the first, second, and third connecting ends, when combined with the fourth connecting end, satisfies a right-angle current flow pattern. This non-circular conductor for GIS disconnect switches combines advantages in current flow and guidance, and can be applied to various disconnect switches.

[0004] However, the above-mentioned patent has certain defects in use. When the GIS needs to adjust the length of the internal conductor, it cannot be done, and the conductor has to be redesigned and manufactured.

[0005] To address these issues, a GIS aluminum alloy conductor is proposed here. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a GIS aluminum alloy conductor.

[0007] This utility model is achieved using the following technical solution:

[0008] A GIS aluminum alloy conductor includes a first conductor and a second conductor. The first conductor has a first connecting end at its front end, which is integrally connected to the first conductor. The second conductor has a second connecting end at one end, which is integrally connected to the second conductor. The first connecting end and the second connecting end are respectively provided with mounting holes.

[0009] The first conductor has an adjustment cavity inside it away from the first connection end, and the second conductor passes through the adjustment cavity.

[0010] The adjustment cavity has multiple adjustment holes on its side wall. The second conductor has locking devices on both sides. Each locking device includes a fixing hole located on the side wall at the front end of the second conductor. A locking spring is installed inside the fixing hole. A limiting cover is installed on the fixing hole and fixed to the front end of the fixing hole. A fixing post is installed inside the fixing hole and passes through the limiting cover. The end of the fixing post is fixedly connected to the locking spring. When the second conductor is inserted into the adjustment cavity, the fixing post is engaged in the adjustment hole.

[0011] The second conductor is provided with a sliding groove, and a connecting plate is provided in the sliding groove. Multiple lifting springs are provided between the sliding groove and the connecting plate. Under the action of the lifting springs, the upper surface of the connecting plate is in close contact with the inner wall of the adjustment cavity.

[0012] The first connecting end and the second connecting end are respectively located at the center of the sidewall of the first conductor and the second conductor, and the upper and lower surfaces of the first connecting end and the second connecting end are horizontal planes.

[0013] The present invention has the following advantages over the prior art:

[0014] 1. By setting a first conductor and a second conductor, with the second conductor adjustablely inserted inside the first conductor, and the two being detachable and retractable, not only can they be disassembled, but their length can also be adjusted by stretching, thus achieving flexible adjustment and stable connection between the conductors, improving the operating efficiency and safety of GIS equipment.

[0015] 2. By setting a lifting spring, a sliding groove, and a connecting plate on the second conductor, the contact area and fit between the second conductor and the inner wall of the adjustment cavity are increased, further improving the stability of the connection and ensuring a tight connection.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown, a GIS aluminum alloy conductor includes a first conductor 1 and a second conductor 4. The conductors, as the main conductive parts, are responsible for transmitting current. The main body is made of aluminum alloy, which has good conductivity and corrosion resistance. The first conductor 1 has a first connecting end 11 at its front end, which is integrally connected to the first conductor 1. The second conductor 4 has a second connecting end 2 at one end, which is integrally connected to the second conductor 4. Mounting holes 3 are respectively provided on the first connecting end 11 and the second connecting end 2; the mounting holes 3 facilitate connection and fixation with other components or equipment.

[0025] An adjustment cavity 13 is provided inside the first conductor 1 away from the first connection end 11. The second conductor 4 passes through the adjustment cavity 13. The adjustment cavity 13 is used to accommodate the second conductor 4 and realize the relative displacement and adjustment between the two. The position of the second conductor 4 in the first conductor 1 can be adjusted according to actual needs to adapt to different situations.

[0026] Different installation or operation requirements.

[0027] The adjustment cavity 13 has multiple adjustment holes 12 on its side wall. Locking devices are provided on both sides of the second conductor 4. The adjustment holes 12 cooperate with the locking devices on the second conductor 4 to fix its position. The locking device includes a fixing hole 42 located on the side wall at the front end of the second conductor 4. A locking spring 44 is installed inside the fixing hole 42. A limiting cover 43 is provided on the fixing hole 42, fixed to the front end of the fixing hole 42 to prevent the locking spring 44 from falling off. A fixing post 41 is installed inside the fixing hole 42, penetrating the limiting cover 43. The end of the fixing post 41 is fixedly connected to the locking spring 44. When the second conductor 4 passes through the adjustment cavity 13, the fixing post 41 engages within the adjustment hole 12. When the second conductor 4 passes through the adjustment cavity 13 and reaches a predetermined position, the fixing post 41 engages within the adjustment hole 12 under the action of the locking spring 44, achieving a stable lock.

[0028] The second conductor 4 is provided with a groove 45, and a connecting plate 47 is provided inside the groove 45. The connecting plate 47 is used to increase the contact area between the second conductor 4 and the inner wall of the adjustment cavity 13, thereby improving stability. The material of the connecting plate 47 is the same as that of the conductor. Multiple lifting springs 46 are provided between the groove 45 and the connecting plate 47. Under the action of the lifting springs 46, the upper surface of the connecting plate 47 is tightly attached to the inner wall of the adjustment cavity 13. The lifting springs 46 provide elastic force to the connecting plate 47, so that the upper surface of the connecting plate 47 always remains in close contact with the inner wall of the adjustment cavity 13. This design further enhances the stability of the connection and reduces loosening caused by vibration or temperature changes.

[0029] The first connecting end 11 and the second connecting end 2 are respectively located at the center of the sidewall of the first conductor 1 and the second conductor 4. The upper and lower surfaces of the first connecting end 11 and the second connecting end 2 are horizontal planes. The horizontal plane setting facilitates docking with horizontal mounting surfaces or other horizontal connecting components, thereby improving the convenience and accuracy of installation.

[0030] The working principle of this utility model is as follows: In the initial state, the first conductor 1 and the second conductor 4 are relatively independent through the adjustment cavity 13 and the locking device, but are in an adjustable positional relationship. The locking spring 44 is in a natural state, the fixing post 41 is not inserted into the adjustment hole 12, and the second conductor 4 can move freely in the adjustment cavity 13. At this time, the lifting spring 46 and the slide groove 45 are in a compressed state, providing an upward elastic force to the connecting plate 47, so that it is tightly attached to the inner wall of the adjustment cavity 13.

[0031] According to the installation or operation requirements of GIS equipment, it is necessary to adjust the position of the second conductor 4. The second conductor 4 can be manually pushed to move in the adjustment cavity 13. When the second conductor 4 moves to the predetermined position, the locking device starts to play its role. The fixing column 41 gradually approaches the adjustment hole 12 under the action of the locking spring 44 and finally gets stuck in it, thereby fixing the second conductor 4.

[0032] As the second conductor 4 moves, the connecting plate 47 slides in the groove 45, while the lifting spring 46 compresses or extends according to the position change of the connecting plate 47 to keep the connecting plate 47 in close contact with the inner wall of the adjusting cavity 13.

[0033] When it is necessary to adjust the position of the second conductor 4, the fixing post 41 on the locking device can be pushed manually or with the help of tools to disengage it from the adjustment hole 12. At this time, the second conductor 4 can move freely in the adjustment cavity 13 to make necessary adjustments.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
