Description

Technical Field

[0001] This application belongs to the field of current transformer installation technology, and particularly relates to a stable installation structure for a GIS current transformer. Background Technology

[0002] A current transformer is an instrument that measures a large primary current by converting a small secondary current into a large primary current based on the principle of electromagnetic induction. A current transformer consists of a closed iron core and windings. Current transformers are divided into two main categories: electromagnetic current transformers and electronic current transformers. An installation structure is used to install the GIS current transformer in the required location.

[0003] The existing utility model with authorization announcement number CN210535456U discloses an installation structure for a current transformer, including a current transformer body and a mounting bracket. The top surface of the mounting bracket is provided with a slot, the current transformer body is snapped into the inside of the slot, a first spring is uniformly fixed at the bottom of the slot, a movable plate is fixed on the top surface of the first spring, and sliding grooves are symmetrically provided on both sides of the slot.

[0004] The above technical solution facilitates the disassembly of current transformers, making them easier to inspect and maintain, and providing greater flexibility and convenience. However, this solution only allows for the installation of GIS current transformers of one size, and the base dimensions for each size of GIS current transformer are not identical. The dimensions of the mounting structure cannot be adjusted, which greatly reduces its applicability. Consequently, it is necessary to manufacture mounting structures of different sizes to install GIS current transformers of different sizes, resulting in a waste of processing resources.

[0005] To address this issue, we propose a stable installation structure for GIS current transformers. Utility Model Content

[0006] The purpose of this application is to solve the problem in the prior art that it is impossible to install GIS current transformers of different sizes, and to propose a stable installation structure for GIS current transformers.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A stable installation structure for a GIS current transformer includes a mounting base plate. A connecting frame is fixedly connected to the upper surface of the mounting base plate. Two sets of limiting mounting grooves are formed in the inner top wall of the connecting frame. Two L-shaped connecting plates and two L-shaped limiting plates are respectively arranged above the connecting frame. A positioning bolt is threadedly connected inside each L-shaped connecting plate and the inside of each L-shaped limiting plate. Each set of positioning bolts is slidably connected inside the limiting mounting groove. An extrusion plate is sleeved on the outer surface of each set of positioning bolts. The bottom surfaces of the two sets of extrusion plates are in contact with the upper surfaces of the two L-shaped connecting plates and the upper surfaces of the two L-shaped limiting plates, respectively. A positioning slide plate is slidably connected inside each set of limiting mounting grooves. Each set of positioning bolts is threadedly connected inside the positioning slide plate.

[0009] Preferably, the mounting base plate has two sets of mounting bolts connected by internal threads, and the bottom end of each set of mounting bolts penetrates the mounting base plate and extends to the bottom of the mounting base plate.

[0010] Preferably, the inner top wall of the connecting frame is provided with two sets of stabilizing grooves, and two stabilizing sliders are fixedly connected to the bottom surface of each L-shaped connecting plate and the bottom surface of each L-shaped limiting plate. Each set of stabilizing sliders is slidably connected inside the stabilizing groove.

[0011] Preferably, a mounting base is provided above the connecting frame, and the sides of the two L-shaped connecting plates that are close to each other and the sides of the two L-shaped limiting plates that are close to each other are in contact with the outer surface of the mounting base. The main body of the GIS current transformer is fixedly connected to the upper surface of the mounting base.

[0012] Preferably, both sides of the mounting base are fixedly connected with snap-fit ​​buckles, and the two L-shaped connecting plates are provided with snap-fit ​​grooves on their adjacent sides, with each snap-fit ​​buckle snapping into the inside of the snap-fit ​​groove.

[0013] Preferably, each of the two snap fasteners has a pressing block on its opposite side, and each pressing block is slidably connected to the inside of the snap groove. Each of the two L-shaped connecting plates has a positioning cylinder fixedly connected to its opposite side, and each positioning cylinder is connected to the snap groove.

[0014] Preferably, each of the two extrusion blocks has an extrusion rod fixedly connected to one of its opposite sides, and each extrusion rod is slidably connected inside the positioning cylinder.

[0016] In summary, the technical effects and advantages of this application are as follows: By using a mounting base plate, connecting frame, L-shaped connecting plate, and L-shaped limiting plate, the mounting base plate is installed in the required position through a fixing structure. The L-shaped connecting plate and L-shaped limiting plate can clamp GIS current transformers of different sizes placed on the connecting frame, thus facilitating the fixed installation of GIS current transformers of different sizes. Furthermore, the use of limiting mounting grooves, positioning bolts, pressing plates, and positioning slides allows positioning bolts to be connected within the L-shaped connecting plate and L-shaped limiting plate. The sliding of these positioning bolts within the limiting mounting grooves allows the L-shaped connecting plate and L-shaped limiting plate to slide on the connecting frame. Twisting the positioning bolts causes the pressing plate and positioning slide to press against the connecting frame, thereby positioning the L-shaped connecting plate and L-shaped limiting plate and ensuring stable installation of GIS current transformers of different sizes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4A stable mounting structure for a GIS current transformer includes a mounting base plate 1. The mounting base plate 1 has two sets of mounting bolts 2 internally threaded. The bottom end of each set of mounting bolts 2 penetrates the mounting base plate 1 and extends to the bottom of the mounting base plate 1. The mounting base plate 1 is fixed in the required position using the two sets of mounting bolts 2, thereby enabling the stable mounting structure of the GIS current transformer to be installed in the required position.

[0024] A connecting frame 3 is fixedly connected to the upper surface of the mounting base plate 1. Two sets of limiting mounting grooves 4 are provided on the inner top wall of the connecting frame 3. Two L-shaped connecting plates 6 and two L-shaped limiting plates 10 are respectively provided on the upper part of the connecting frame 3. Two sets of stabilizing slide grooves 5 are provided on the inner top wall of the connecting frame 3. Two stabilizing sliders 11 are fixedly connected to the bottom surface of each L-shaped connecting plate 6 and the bottom surface of each L-shaped limiting plate 10. Each set of stabilizing sliders 11 is slidably connected inside the stabilizing slide groove 5. By using the stabilizing sliders 11 to slide in the stabilizing slide groove 5, the movement of the two L-shaped connecting plates 6 and the two L-shaped limiting plates 10 can be limited, so that the GIS current transformer can be stably installed and fixed using the two L-shaped connecting plates 6 and the two L-shaped limiting plates 10.

[0025] Each L-shaped connecting plate 6 and each L-shaped limiting plate 10 are threaded with positioning bolts 9. Each set of positioning bolts 9 is slidably connected to the inside of the limiting mounting groove 4. A mounting base 20 is provided above the connecting frame 3. The sides of the two L-shaped connecting plates 6 and the sides of the two L-shaped limiting plates 10 that are close to each other are in contact with the outer surface of the mounting base 20. The upper surface of the mounting base 20 is fixedly connected to the GIS current transformer body 21. By sliding the two L-shaped connecting plates 6 and the two L-shaped limiting plates 10 on the connecting frame 3, the mounting base 20 placed on the connecting frame 3 can be clamped to limit the horizontal movement of the mounting base 20, thereby facilitating the installation and fixing of the GIS current transformer body 21.

[0026] Each set of positioning bolts 9 has an extrusion plate 7 fitted on its outer surface. The bottom surfaces of the two sets of extrusion plates 7 are in contact with the upper surfaces of the two L-shaped connecting plates 6 and the upper surfaces of the two L-shaped limiting plates 10, respectively. The two sides of the mounting base 20 are fixedly connected with snap-fit ​​buckles 13. The two L-shaped connecting plates 6 are provided with snap-fit ​​grooves 12 on their sides that are close to each other. Each snap-fit ​​buckle 13 is snapped into the inside of the snap-fit ​​groove 12. By using the snap-fit ​​buckle 13 to snap into the inside of the snap-fit ​​groove 12, the vertical movement of the mounting base 20 placed on the connecting frame 3 can be limited, thereby further installing and fixing the GIS current transformer body 21.

[0027] Each set of limiting mounting slots 4 has a slidably connected positioning slide plate 8 inside, and each set of positioning bolts 9 is threadedly connected to the inside of the positioning slide plate 8. Each of the two snap-fit ​​buckles 13 is provided with a pressing block 19 on the side away from each other. Each pressing block 19 is slidably connected to the inside of the snap-fit ​​groove 12. Each of the two L-shaped connecting plates 6 is fixedly connected with a positioning cylinder 14 on the side away from each other. Each positioning cylinder 14 is connected to the snap-fit ​​groove 12. By sliding the pressing block 19 inside the snap-fit ​​groove 12, the snap-fit ​​buckle 13 inside the snap-fit ​​groove 12 can be pressed by the pressing block 19, so as to facilitate the removal of the mounting base 20 placed on the connecting frame 3.

[0028] Each of the two extrusion blocks 19 has an extrusion rod 15 fixedly connected to one of their opposite sides. Each extrusion rod 15 is slidably connected inside the positioning cylinder 14. By manually pressing the extrusion rod 15 inside the positioning cylinder 14, the extrusion block 19 can be extruded using the sliding extrusion rod 15, thus facilitating the operation of the extrusion block 19 to extrude the snap fastener 13 in the snap fastener groove 12.

[0029] Each pressing rod 15 has a fixed plate 16 fixedly connected to its outer surface. Compression springs 17 are fixedly connected to the sides of the two fixed plates 16 that are close to each other. Buffer rings 18 are fixedly connected to the ends of the two compression springs 17 that are close to each other. The sides of the two buffer rings 18 that are close to each other are in contact with the sides of the two L-shaped connecting plates 6 that are close to each other. The structure composed of the fixed plate 16, compression springs 17 and buffer rings 18 can restore the pressing rod 15 to its unused state after use.

[0030] The working principle of this utility model is as follows: When using this stable installation structure to install GIS current transformers of different sizes, the mounting base plate 1 is first manually placed in the required position, and the mounting bolts 2 are threaded through the mounting base plate 1 and connected to the required position, so that the installation structure can be installed in the required position. Then, the mounting base 20 under the GIS current transformer body 21 is placed in the center of the connecting frame 3 by manual means, and the positioning bolts 9 in the positioning slide plate 8 are manually twisted, so that the pressing plate 7 and the positioning slide plate 8 do not press against the L-shaped connecting plate 6 and the L-shaped limiting plate 10 and the connecting frame 3, so that the L-shaped connecting plate 6 and the L-shaped limiting plate 10 can move along the limiting mounting groove 4 on the connecting frame 3 until the two L-shaped connecting plates 6 and the two L-shaped limiting plates 10 respectively contact the four sides of the mounting base 20, and limit the horizontal direction of the mounting base 20.

[0031] Simultaneously, the snap-fit ​​buckles 13 fixed on both sides of the mounting base 20 can be snapped into the snap-fit ​​grooves 12 opened on the inner side of the L-shaped connecting plate 6, which can limit the vertical direction of the mounting base 20. At this time, by manually twisting the positioning bolts 9, the L-shaped connecting plate 6 and the L-shaped limiting plate 10 can be squeezed against the connecting frame 3 by the squeezing plate 7 and the positioning slide plate 8, which can position the L-shaped connecting plate 6 and the L-shaped limiting plate 10 on the connecting frame 3, thereby completing the installation of the GIS current transformer. When disassembling the GIS current transformer for installation, simply press the squeezing rod 15 in the positioning cylinder 14 to squeeze the snap-fit ​​buckles 13 in the snap-fit ​​groove 12 by the squeezing block 19, so that the snap-fit ​​buckles 13 can be pulled out from the snap-fit ​​groove 12, and the mounting base 20 can be removed from the connecting frame 3. When it is necessary to install GIS current transformers of different sizes, simply repeat the above steps to install GIS current transformers of different sizes.
