Description

Technical Field

[0002] At present, when carrying out maintenance work on 220kVGIS busbars, when it comes to the arrangement of safety measures to isolate the adjacent operating busbars, operators generally arrange safety measures by hanging a safety fence with a "Stop, High Voltage Danger" sign. However, since the busbar is usually located at a higher position, the height of this safety fence also needs to be set higher accordingly, and the safety fence is usually fixed to the busbar by hanging. Therefore, it is necessary to use a binding belt to ensure that the safety measure is stable and does not fall off, so that the operators need to bear the risk of high-altitude work when setting up the safety fence.

[0003] And if an escalator is needed for aerial work, because the GIS busbar is generally long, the safety fence also needs multiple fixed points, and the fixed points of the safety fence will be set at multiple locations along the busbar. Every time the operator fixes a fixed point, he needs to move the escalator to the next fixed point. The transportation process is time-consuming and labor-intensive, and it is also very dangerous for the operators at high altitudes. Summary of the invention

[0026] The present application is further described in detail below in conjunction with the accompanying drawings and implementation methods. It is particularly noted that the following implementation methods are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following implementation methods are only some implementation methods of the present application rather than all implementation methods. All other implementation methods obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] The terms "first", "second" and "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second" and "third" can explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, and the manner is such as two, three, etc., unless otherwise clearly and specifically defined. All directional indications in the implementation mode of this application (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. The manner, such as a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0028] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] At present, when carrying out maintenance work on 220kV GIS (Gas Insulated Switchgear) busbars, when it comes to the arrangement of safety measures to isolate from adjacent operating busbars, operators generally arrange safety measures by using safety fences with "Stop, High Voltage Danger" signs. GIS busbars are usually equipped with busbar bellows, and the outer periphery of adjacent multi-section busbar bellows is connected and fixed with bellows connecting rods. For the currently common safety fences, the fixing point can be set on the bellows connecting rod. After the safety fence is fixed to the bellows connecting rod with a binding belt, the safety fence can cover the busbar bellows on at least one side, thereby playing a protective and reminder effect.

[0030] However, since the busbar is usually located at a higher position, the height of the safety fence also needs to be set higher accordingly, and the safety fence is usually fixed to the busbar by hanging. Therefore, it is necessary to use a lashing belt to ensure that the safety measure is stable and does not fall off, so that the operator needs to bear the risk of high-altitude operation when setting up the safety fence.

[0031] And if an escalator is needed for aerial work, because the GIS busbar is generally long, the safety fence also needs multiple fixed points, and the fixed points of the safety fence will be set at multiple locations along the busbar. Every time the operator fixes a fixed point, he needs to move the escalator to the next fixed point. The transportation process is time-consuming and labor-intensive, and it is also very dangerous for the operators at high altitudes.

[0032] In order to improve or solve the above technical problems, the inventors of the present application have proposed at least the following embodiments after long-term research.

[0033] See also Figures 1 to 6 , Figure 1 It is a schematic diagram of the assembly structure of an embodiment of a busbar safety fence provided in the present application. Figure 2 It is a schematic diagram of the assembly structure of a busbar safety fence embodiment provided in the present application from another angle. Figure 3 It is a schematic diagram of the assembly structure of a busbar safety fence embodiment provided in the present application from another angle. Figure 4 It is a schematic cross-sectional structure diagram of the busbar safety fence and operating lever provided in this application. Figure 5 yes Figure 4 Schematic diagram of the local enlarged structure of area A in the middle. Figure 6 yes Figure 4 The embodiment of the present application provides a busbar safety fence 1, which is used to be hung on the bellows connecting rod 4 to play a protective and warning role and ensure the maintenance of the GIS busbar. The busbar safety fence 1 includes a fixing component 2 and a safety fence.

[0034] The fixing assembly 2 may include a hook 21 and a movable member 23. The hook 21 includes a hook body 211 and a first connecting portion 22. The hook body 211 is provided with a groove 212. The movable member 23 includes a stopper 231, a connecting rod 232, and a docking portion 233. The stopper 231 and the docking portion 233 are arranged on the connecting rod 232, and the stopper 231 faces the groove 212. The connecting rod 232 is movably connected to the first connecting portion 22. The docking portion 233 is used to dock the operating rod 6 and drive the stopper 231 and the connecting rod 232 to be relatively close to or away from the groove 212 under the control of the operating rod 6. The stopper 231 is used to stop the bellows connecting rod 4 to limit the bellows connecting rod 4 in the groove 212. The safety enclosure 3 may include an enclosure body 31 and a second connecting portion 33. The second connecting portion 33 is arranged on the enclosure body 31, and the second connecting portion 33 is connected to the first connecting portion 22.

[0035] In the structure provided in the embodiment, the groove 212 of the hook 21 is used to accommodate the bellows connecting rod 4, and the top portion 231 facing the groove 212 is used to limit the bellows connecting rod 4 in the groove 212, so that the fixing component 2 is detachably connected to the bellows connecting rod 4, and because the hook 21 is also connected to the safety enclosure 3, the safety enclosure 3 can be relatively fixed to the bellows connecting rod 4 under the action of the fixing component 2, and because the fixing component 2 has a docking portion 233, the process of hanging the busbar safety fence 1 on the bellows connecting rod 4 can be performed by the operator using the operating rod 6, so that the operator does not need to frequently move the position and / or climb to a high place to perform complex high-altitude operations, thereby improving the safety of laying the busbar safety fence 1 and reducing the manpower and material consumption when laying the busbar safety fence 1. In addition, the use of the operating rod 6 is simpler and more labor-saving than using a binding belt to manually tie, and the structure provided by the present application also greatly improves the efficiency of laying the busbar safety fence 1.

[0036] Specifically, if Figure 5 As shown, the second connection part 33 may be provided with a connection hole 331, and the first connection part 22 may be provided with a second screw hole 222, and the connection hole 331 is opened corresponding to the second screw hole 222. The busbar safety fence 1 may also include a locking screw 7, which is used to pass through the connection hole 331 and be screwed with the second screw hole 222, so as to connect the second connection part 33 with the first connection part 22.

[0037] In a specific embodiment of the present application, the connecting rod 232 may include a screw rod, the first connecting portion 22 has a first screw hole 221, and the screw rod is engaged with the first screw hole 221. The docking portion 233 may be fixed to one end of the screw rod, and the abutting portion 231 may be rotatably connected to the other end of the screw rod. When the operating rod 6 drives the docking portion 233 to rotate, the screw rod may rotate relative to the first screw hole 221, and the movable member 23 may move relative to the hook 21.

[0038] Through the structure provided in this embodiment, the docking portion 233 is utilized to dock with the operating rod 6, so that the movable member 23 can rotate under the control of the operating rod 6, and due to the meshing relationship between the screw rod and the first screw hole 221, the movable member 23 can move toward or away from the groove 212 as the rotation direction is adjusted. Since the abutting top portion 231 is rotatably connected to the screw rod, the abutting top portion 231 does not rotate synchronously while moving toward or away from the groove 212 as the screw rod moves, thereby being able to flexibly control the distance between the abutting top portion 231 and the groove 212, thereby being able to adapt to bellows connecting rods 4 of different sizes while being flexible in operation, thereby improving the versatility of the fixing assembly 2.

[0039] In a specific embodiment of the present application, there may be multiple second connection parts 33. Multiple second connection parts 33 may be evenly arranged on the edge of the enclosure body 31 in parallel with the extension direction of the bellows connecting rod 4. The number of the fixing components 2 corresponds to the number of the second connection parts 33.

[0040] For the busbar safety fence 1 used for protection and reminder, the length and width are usually large, so that it can be sufficiently eye-catching and can effectively cover the GIS busbar part that needs to be protected, such as the SF6 pressure gauge, etc. The length refers to the dimension in the extension direction of the bellows connecting rod 4, and the width refers to the dimension in the direction perpendicular to the bellows connecting rod 4.

[0041] Therefore, for a busbar safety fence 1 with a large length and width, multiple second connecting parts 33 and multiple fixing components 2 can be provided to evenly distribute the mass of the busbar safety fence 1 and reduce the shaking amplitude of the busbar safety fence 1, thereby stably fixing the busbar safety fence 1 to the corrugated pipe connecting rod 4, thereby improving the stability and safety of GIS busbar maintenance operations.

[0042] In a specific embodiment of the present application, the edge of the enclosure body 31 includes an upper edge 312 and a lower edge 313 arranged at intervals. The upper edge 312 and the lower edge 313 are parallel to the extension direction of the bellows connecting rod 4, and a plurality of second connecting portions 33 are evenly arranged on the upper edge 312 and the lower edge 313, and the fixing assembly 2 adjacent to the upper edge 312 and the fixing assembly 2 adjacent to the lower edge 313 are connected to different bellows connecting rods 4.

[0043] In order to play a warning role, the busbar safety fence 1 is usually not set parallel to the horizontal plane, so the upper edge 312 can be an edge of the enclosure body 31 that is higher in the vertical direction, and the lower edge 313 can be an edge of the enclosure body 31 that is lower in the vertical direction. The fixing components 2 adjacent to the upper edge 312 and the lower edge 313 are respectively connected to different bellows connecting rods 4, so as to play a pulling effect at multiple positions of the enclosure body 31, prompting the enclosure body 31 to unfold between different bellows connecting rods 4, and can reduce the shaking amplitude of the busbar safety fence 1, improve the structural stability, so as to fully play the role of protection and warning.

[0044] Among them, see Figure 1 , Figure 2 There are usually multiple bellows connecting rods 4 for connecting the bellows, and the multiple bellows connecting rods 4 form a hexahedron around the busbar bellows 5. The busbar safety fence 1 can be installed on the vertical side of the hexahedron and arranged along the length direction of the busbar bellows 5. The fixing components 2 adjacent to the upper edge 312 and the lower edge 313 can be fixed on the two bellows connecting rods 4 forming this surface, so that the busbar safety fence 1 can just cover the side of the busbar bellows 5, fully realizing the protection and warning effects.

[0045] like Figure 5 As shown, under the action of gravity, the groove 212 on the hook body 211 adjacent to the upper edge 312 is arranged downward. Figure 6 In the embodiment, due to the influence of the width of the safety enclosure 3, the lower edge 313 is lower than the bellows connecting rod 4 adjacent to the lower side, so that the groove 212 on the hook body 211 adjacent to the lower edge 313 is also arranged to face downward. However, in the case where the lower edge 313 is higher than the bellows connecting rod 4 adjacent to the lower side, the groove 212 on the hook body 211 adjacent to the lower edge 313 can also be arranged to face upward.

[0046] Optionally, the bellows connecting rod 4 may be a column, and the fixing assembly 2 may rotate relative to the bellows connecting rod 4. The abutting top portion 231 may be provided with a matching groove 231a, and the contour shape of the matching groove 231a is consistent with the contour shape of the outer periphery of the bellows connecting rod 4. Thus, the bellows connecting rod 4 can be closely matched with the fixing assembly 2 when abutting against the bellows connecting rod 4, thereby improving the stability of the connection relationship between the fixing assembly 2 and the bellows connecting rod 4.

[0047] In a specific embodiment of the present application, the safety enclosure 3 may further include a splicing piece 32 , which is disposed at an edge of the enclosure body 31 , and two adjacent enclosure bodies 31 may be connected via the splicing piece 32 .

[0048] Due to the requirement for the length of the busbar safety fence 1, the length of the safety fence 3 is also longer, but different GIS busbars may have different installation requirements. An overly long or short safety fence 3 may not meet the requirements of some GIS busbars, which affects the versatility of the busbar safety fence 1. In addition, an overly long safety fence 3 is not conducive to installation, transportation, and storage, and is very troublesome to use.

[0049] Therefore, the edge of the enclosure body 31 can be provided with a splicing piece 32, and the operator can use the splicing piece 32 to connect two enclosure bodies 31 to meet the use requirements of the on-site situation. During transportation and storage, multiple enclosure bodies 31 can also be separated and stored, which will not take up too much storage space.

[0050] Optionally, the splicing piece 32 may specifically include a zipper 32a, and the zipper 32a may include two corresponding chain belts 322 and a pull head 323. One chain belt 322 is provided on one enclosure body 31, and the other chain belt 322 is provided on another adjacent enclosure body 31, and the pull head 323 is used to slide along the chain belt 322 to mesh the two chain belts 322, thereby connecting two adjacent enclosure bodies 31.

[0051] In a specific embodiment of the present application, the extension direction of the zipper 32a can be perpendicular to the extension direction of the bellows connecting rod 4. The zipper 32a perpendicular to the extension direction of the bellows connecting rod 4 can effectively divide the length of the safety enclosure 3.

[0052] The safety enclosure 3 is usually made of flexible plastic or cloth. Compared with the complete and long safety enclosure 3, the safety enclosure 3 formed by connecting multiple enclosure bodies 31 through the zipper 32a has higher strength and stronger deformation resistance due to the higher strength and hardness of the meshing part of the two chain belts 322. It can reduce the shaking amplitude of the busbar safety fence 1 and improve the structural stability. In addition, the zipper 32a can also help the safety enclosure 3 to expand in the width direction, which can improve the stability of the busbar safety fence 1.

[0053] In a specific embodiment of the present application, the enclosure body 31 may specifically include a flexible fabric 311 and a fixing frame 9. Figure 7 , Figure 8 , Figure 7 It is a structural schematic diagram of an embodiment of an enclosure body provided in the present application. Figure 8 31 is a schematic diagram of another embodiment of the enclosure body provided by the present application. The fixing frame 9 may include a longitudinal fixing rod 91, and the longitudinal fixing rod 91 is arranged parallel to the extension direction of the zipper 32a. The second connecting portion 33, the upper edge 312 and the lower edge 313 are connected to the flexible fabric 311.

[0054] Through the structure provided by this specific embodiment, on the basis of the zipper 32a, the longitudinal fixing rod 91 can be used to further provide support for the enclosure body 31, helping the flexible fabric 311 to unfold in the width direction so that it is not easy to roll up, and can reduce the shaking amplitude of the busbar safety fence 1, improve the structural stability, so that it can play a more stable role in protection and warning.

[0055] In a specific embodiment of the present application, the fixing frame 9 may further include two transverse fixing rods 92. The two transverse fixing rods 92 are connected to the longitudinal fixing rod 91, and the transverse fixing rods 92 are parallel to the extension direction of the bellows connecting rod 4, and are respectively connected to the upper edge 312 and the lower edge 313.

[0056] In the structure provided in this specific embodiment, two transverse fixing rods 92 are adjacent to the upper edge 312 and the lower edge 313 respectively, so as to help the flexible fabric 311 to unfold in the length direction, making it difficult to roll up, so as to play a more stable role in protection and warning. And due to the mass of the transverse fixing rod 92 of the lower edge 313 itself, the flexible fabric 311 can also be urged to unfold in the width direction under the action of gravity. Through the cooperation of the transverse fixing rod 92 and the longitudinal fixing rod 91, the flexible fabric 311 can be urged to unfold, and the shaking amplitude of the busbar safety fence 1 can be reduced, the structural stability can be improved, and its protection and warning functions can be fully exerted.

[0057] Figure 7 , Figure 8 Two different structures of the fixing frame 9 are shown. Figure 7 In the structure of the embodiment of the enclosure body 31 shown, the number of longitudinal fixing rods 91 is two, and the two longitudinal fixing rods 91 are arranged on the left and right sides of the flexible fabric 311, so that the two longitudinal fixing rods 91 can cooperate with the two transverse fixing rods 92 to form a fixing frame 9 that is approximately a quadrilateral.

[0058] exist Figure 8 In the structure of the embodiment of the enclosure body 31 shown, the number of longitudinal fixing rods 91 is one, and one longitudinal fixing rod 91 is arranged in the middle of the flexible fabric 311. The two ends of the longitudinal fixing rod 91 are respectively connected to two transverse fixing rods 92, thereby forming a fixing frame 9 that is approximately in the shape of an "I".

[0059] It should be noted that Figure 7 , Figure 8 As an example only, the number of the longitudinal fixing rods 91 and the transverse fixing rods 92, and the connection method between the two are not limited to the following. Figure 7 , Figure 8 The structures shown are limited.

[0060] In a specific embodiment of the present application, the fixing frame 9 may include a hollow tube.

[0061] Although the existence of the fixing frame 9 provides support for the flexible fabric 311 and improves the structural strength of the busbar safety fence 1, it also increases the mass of the busbar safety fence 1 and increases the burden on the bellows connecting rod 4. Therefore, the fixing frame 9 may include a hollow tube, so that the mass of the busbar safety fence 1 can be reduced to a certain extent without excessively affecting the structural strength of the busbar safety fence 1, thereby improving the stability and safety of the GIS busbar maintenance operation.

[0062] In a specific embodiment of the present application, the flexible fabric 311 may have warning colors, patterns and / or text. Figure 1 , Figure 2 As shown, the flexible fabric 311 may be provided with warning words of "Stop, High Voltage Danger" to serve as a warning to personnel not related to the operation, thereby reducing the probability of critical situations occurring during GIS bus maintenance operations and improving the safety of GIS bus maintenance operations.

[0063] Optionally, the flexible fabric 311 can be set to a striking color such as yellow or red, so as to achieve a warning effect by using color.

[0064] Optionally, a plurality of ventilation holes 8 are evenly arranged on the surface of the flexible fabric 311. For the purpose of safety protection, the flexible fabric 311 has a certain area.

[0065] When there is airflow, the flexible fabric 311 may cause a certain resistance to the airflow, causing the flexible fabric 311 to deform and / or shake like a sail under the action of the airflow. When the wind force of the airflow is strong, the changes in the flexible fabric 311 may affect the bellows connecting rod 4 and even the busbar, causing the busbar to shake as a whole, which not only threatens the safety of high-altitude workers, but may also cause power line failures.

[0066] To address this problem, the surface of the flexible fabric 311 provided in this embodiment can be evenly provided with multiple ventilation holes 8, and the airflow can pass through the flexible fabric 311 through these ventilation holes 8, reducing the deformation and shaking amplitude of the flexible fabric 311 caused by the airflow, thereby reducing the impact of the airflow on the power lines and operators, and can improve the stability of the busbar safety fence 1, effectively ensuring the safety of GIS busbar maintenance operations.

[0067] exist Figure 7 , Figure 8 Two different forms of ventilation holes 8 are shown in FIG. Figure 7In the structure of the embodiment of the enclosure body 31 shown, the ventilation holes 8 are multiple nearly circular through holes provided on the flexible fabric 311. The nearly circular through holes may be directly formed on the flexible fabric 311 when the flexible fabric 311 is produced, or may be subsequently opened on the flexible fabric 311 using a punching device such as a puncher. In the latter case, the flexible fabric 311 originally located at the position of the nearly circular through holes is removed during the punching process.

[0068] exist Figure 8 In the structure of the embodiment of the enclosure body 31 shown, when there is no airflow passing through, the ventilation holes 8 are multiple arc-shaped fine holes arranged on the flexible fabric 311. The arc-shaped fine holes can be directly formed on the flexible fabric 311 when the flexible fabric 311 is produced, or can be subsequently opened on the flexible fabric 311 using a punching device such as a puncher. The flexible fabric 311 within the circumference where the arc-shaped holes are located is still connected to the flexible fabric 311 as a whole. When there is airflow passing through, this part of the flexible fabric 311 will be lifted due to the presence of the ventilation holes 8, so that the area of ​​the ventilation holes 8 is increased, and the airflow can pass through the ventilation holes 8.

[0069] For the flexible fabric 311 printed with warning colors, patterns and / or words, due to the absence of the flexible fabric 311 at the nearly circular through hole, the following Figure 7 The shape of the ventilation hole 8 shown may not be able to maintain the integrity of the color, pattern and / or text area, which may affect the warning effect of the busbar safety fence 1. Figure 8 In the shape of the ventilation hole 8 shown, the flexible fabric 311 within the circle where the arc-shaped fine holes are located is not missing, so that the color, pattern and / or text area can be kept roughly intact while the airflow passes through, and the warning function of the busbar safety fence 1 can be better achieved.
