Description

Technical Field

[0001] The invention relates to the technical field of auxiliary support for electric wires, in particular to a support assembly for a gas-insulated power transmission line. Background Art

[0002] Gas-insulated transmission line (GIL) is a transmission line technology that uses gas as an insulating medium. Unlike traditional overhead lines or cables, GIL (gas-insulated transmission line) encapsulates high-voltage wires in metal pipes and fills them with insulating gas, usually sulfur hexafluoride or dry air, to achieve the purpose of insulation and power transmission; The common gas-insulated transmission lines on the market need to be supported by support components. Since gas needs to be injected on the outside of the transmission line for insulation, the center of the line may fall when it is built over a long distance. This causes both ends of the line to be pulled for a long time, and it is easy for both ends of the line to be detached from the equipment. Therefore, it is necessary to set a support component at the center of the line to support it upward, but the transmission lines are laid at different heights at each location, and most of the support components supporting the transmission lines are customized or telescopic. However, customized support components have poor versatility, and telescopic support components not only require manual adjustment, but are also difficult to support for a long time. The connection is easily affected by the surrounding environment and rusted, and then broken. After the support component supports the transmission line, it is difficult to continue to fine-tune the height, and the installation and measurement efficiency is slow. Summary of the invention

[0032] In the present embodiment, the heat generated by the wire body 5 wrapped by the through groove can be directed to the heat sink 412 and the heat sink fins 404 to exchange heat with the surrounding air, thereby reducing the heat generated by the wire body 5 wrapped by the through groove to a certain extent, avoiding the situation where the heat accumulates in the through groove and is difficult to be discharged to the outside, causing the wire body 5 to short-circuit due to heat.

[0033] In an optional embodiment: the aluminum sheet 602, the aluminum nitride layer 601 and the copper sheet 6 are fixed in a stacked state, and the aluminum sheet 602, the aluminum nitride layer 601 and the copper sheet 6 are fixed by hot pressing, the thickness of the copper sheet 6 is 40μm, the thickness of the aluminum nitride layer 601 is 0.2mm, and the thickness of the aluminum sheet 602 is 0.5mm.

[0034] In this embodiment: the copper sheet 6 is used as the innermost layer material and is directly wrapped around the surface of the wire body 5. The aluminum nitride layer 601 can further conduct the heat transferred from the copper layer, and the purpose of the aluminum sheet 602 is to transfer the heat to the heat sink 412 and the heat sink fins 404, and dissipate the heat to the surrounding environment through the heat sink fins 404.

[0035] Working principle: During installation, place the base plate 1 in the set area. After placement, insert anchor bolts 101 at the four corners of the base plate 1 and connect the anchor bolts 101 to the ground. Then take out the fixing frame 3. According to the number of wire bodies 5, determine whether to install additional lower splicing clamps 405 and upper splicing clamps 401 above the fixing plate 4 on the top of the fixing frame 3. If not, only use the fixed lower clamps 406 and fixed upper clamps 407 fixed on the top of the fixing plate 4. The wire body 5 is placed in the through groove opened above the fixed lower clamping plate 406, and the surface of the wire body 5 contacts the copper sheet 6. Then the through groove at the bottom of the fixed upper clamping plate 407 is sleeved on the outside of the wire body 5. At this time, the fixed lower clamping plate 406 and the fixed upper clamping plate 407 are in a docking state. The bolts 409 are taken out and inserted into the mounting plates 402 at the left and right ends of the fixed upper clamping plate 407 and the fixed lower clamping plate 406 to fix the fixed lower clamping plate 406 and the fixed upper clamping plate 407.If the number of wire bodies 5 exceeds the number of through slots above the fixed lower clamping plate 406, it is necessary to additionally install the spliced ​​lower clamping plate 405 and the spliced ​​upper clamping plate 401, and place the spliced ​​lower clamping plate 405 from top to bottom on the top of the fixed upper clamping plate 407. At this time, the positioning blocks 408 at the bottom of the spliced ​​lower clamping plate 405 have been inserted into the inner side of the L-shaped plate 403 at the four corners of the top of the fixed upper clamping plate 407 until the bottom of the spliced ​​lower clamping plate 405 contacts the heat dissipation fins 404 at the top of the fixed upper clamping plate 407. Then, remove the screws 410 and insert the screws 410 from the outside into the L-shaped plate 403 , let the L-shaped plate 403 be fixedly connected with the positioning block 408. After installing the splicing lower clamping plate 405, repeat the operation in the manner of placing the wire body 5 on the fixed lower clamping plate 406, and finally use the splicing upper clamping plate 401 to cover the wire body 5. If the number of wire bodies 5 restricted by a set of splicing upper clamping plates 401 and splicing lower clamping plates 405 is insufficient, the splicing upper clamping plates 401 and splicing lower clamping plates 405 can be stacked according to the above operation. After the wire body 5 is restricted, the bottom of the fixing frame 3 is connected with the top plate 202 above the inner side of the bottom shell 2 on the top of the bottom plate 1. Fine adjustment is required for fixing When the height of the plate 4 is adjusted, the driving motor 203 inside the hollow shell 201 below the left and right end surfaces of the bottom shell 2 is turned on, and the driving motor 203 drives the threaded rod 204 at the output end to rotate on the left and right end surfaces of the partition 205, and the moving block 206 outside the threaded rod 204 drives the top plate 202 to move longitudinally through the connecting rod 207, and simultaneously drives the fixing frame 3 and the fixing plate 4 at the top thereof to move longitudinally. After fine-tuning, the driving motor 203 can be turned off, and the wire body 5 can be used normally. The heat generated by the wire body 5 during use is transferred to the fixing frame 3 by the copper sheet 6, the aluminum nitride layer 601 and the aluminum sheet 602. At the lower clamping plate 406, the fixed upper clamping plate 407, the spliced ​​lower clamping plate 405 and the spliced ​​upper clamping plate 401, since the heat sink 412 arranged inside the groove 411 opened inside the spliced ​​upper clamping plate 401 and the fixed upper clamping plate 407 is close to the aluminum sheet 602, most of the heat is transferred to the heat sink 412, and then the heat exchange with the surrounding air is carried out through the heat sink fins 404 on the top of the heat sink 412, which reduces the heat generated by the wire body 5 wrapped by the through groove to a certain extent, and avoids the situation that the heat is accumulated in the through groove and is difficult to be discharged to the outside, and the wire body 5 is short-circuited due to heat. ;
