Technical Field

[0001] This utility model relates to the field of high voltage switchgear technology, specifically to a bushing base for GIS. Background Technology

[0002] A GIS bushing is an insulating device in GIS equipment used to connect internal high-voltage conductors to external overhead lines, cables, or transformers. It typically consists of three parts: a conductor, an insulator, and a metal flange. By filling with SF6 gas or using composite insulating materials, it ensures the safe transmission of high-voltage electrical energy within a sealed metal casing, while isolating the internal components from the influence of the external environment. The bushing base is a key structural component in gas-insulated metal-enclosed switchgear (GIS) used to fix and support the bushing. Its core function is to ensure a stable connection between the bushing and the GIS equipment body, while maintaining insulation performance and electric field uniformity. The mechanical stability and insulating seal between the bushing and the GIS body must be ensured.

[0003] Traditional GIS sleeve bases are mostly one-piece fixed designs with insufficient buffer design, weak impact resistance, and lack of dynamic shock absorption structure. Mechanical collisions can easily cause the base to deform or the flange seal to fail, leading to gas leakage. Therefore, it is particularly important to improve the existing GIS sleeve bases and design a new type of GIS sleeve base to solve the above-mentioned technical defects and improve the overall practicality of GIS sleeve bases. Utility Model Content

[0004] The purpose of this utility model is to provide a GIS sleeve base that can buffer the GIS sleeve base when it encounters a collision, avoiding direct contact and damage caused by impact, thereby preventing the GIS sleeve base from being damaged by collision, extending its service life, and at the same time, making installation convenient and quick, improving work efficiency, and improving the overall practicality of the GIS sleeve base, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A GIS sleeve base includes a base body, a fixing block fixedly connected to the bottom of the base body, first buffer grooves formed on both sides of the fixing block away from the base body, a receiving block slidably connected to the outside of the fixing block and at the bottom of the base body, a second buffer groove formed on the top of the receiving block, a protrusion fixedly connected to the top inside the second buffer groove, and multiple sets of equally spaced spring dampers fixedly connected inside the second buffer groove and at the bottom of the fixing block.

[0006] As a preferred embodiment of this utility model, the protrusion is designed to be compatible with the first buffer groove, and the fixing block is designed to be compatible with the second buffer groove.

[0007] As a preferred embodiment of this utility model, sealing pads are fixedly connected to the top and bottom of the first buffer groove.

[0008] As a preferred embodiment of this utility model, mounting blocks are fixedly connected to the bottom of the receiving block and on both sides away from the base body, and mounting holes are opened on the top of both sets of mounting blocks.

[0009] As a preferred embodiment of this utility model, a plurality of equally spaced connecting pipes are fixedly connected to the outer side of the base body and to the top of the receiving block, and a second flange is fixedly connected to the end of the connecting pipe away from the base body.

[0010] As a preferred embodiment of this utility model, a sleeve body is provided inside the connecting pipe and at one end away from the base body, and a third flange is fixedly connected to one end of the sleeve body near the connecting pipe.

[0011] As a preferred embodiment of this utility model, both ends of the base body are fixedly connected to a first flange, and a sealing ring is provided between the second flange and the third flange.

Example

[0015] Please see Figures 1-3 This utility model provides a technical solution: A GIS sleeve base includes a base body 1. A fixing block 105 is fixedly connected to the bottom of the base body 1. First buffer grooves 106 are formed on both sides of the fixing block 105 away from the base body 1. A receiving block 3 is slidably connected to the outside of the fixing block 105 and located at the bottom of the base body 1. A second buffer groove 303 is formed on the top of the receiving block 3. A protrusion 305 is fixedly connected to the top of the inside of the second buffer groove 303. Multiple sets of equally spaced spring dampers 304 are fixedly connected to the inside of the second buffer groove 303 and located at the bottom of the fixing block 105. The protrusion 305 is designed to fit the first buffer groove 106. The fixing block 105 and the second... The buffer groove 303 is designed to be compatible with the first buffer groove 106. The top and bottom of the first buffer groove 106 are fixedly connected with sealing pads 4. When the GIS sleeve base is put into use, if the GIS sleeve base encounters a collision, the base body 1 will descend, thereby driving the fixing block 105 to descend in the second buffer groove 303, which will press down the spring damper 304. The spring damper 304 will rebound the force, thereby playing a buffering role. The elasticity of the sealing pad 4 provides a buffer zone for the direct contact between the base body 1 and the receiving block 3, avoiding direct contact and collision damage, thereby preventing the GIS sleeve base from being damaged by collision, extending its service life and improving its practicality.

[0016] Furthermore, mounting blocks 301 are fixedly connected to the bottom of the receiving block 3 and on both sides away from the base body 1. Mounting holes 302 are opened on the top of both sets of mounting blocks 301. When the GIS sleeve base is put into use, the receiving block 3 is installed through the mounting blocks 301 and mounting holes 302, which facilitates quick installation and improves work efficiency.

[0017] The base body 1 has multiple sets of equally spaced connecting pipes 102 fixedly connected to the outer side and top of the receiving block 3. A second flange 103 is fixedly connected to the end of the connecting pipe 102 away from the base body 1. A sleeve body 2 is provided inside the connecting pipe 102 and away from the base body 1. A third flange 201 is fixedly connected to the end of the sleeve body 2 near the connecting pipe 102. Both ends of the base body 1 are fixedly connected to a first flange 101. A sealing ring 104 is provided between the second flange 103 and the third flange 201. When the GIS sleeve base is put into use, the sleeve body 2 is inserted into the inside of the connecting pipe 102, and then the sleeve body 2 is fixed to the base body 1 by the second flange 103, the sealing ring 104 and the third flange 201, thereby completing the installation of the GIS sleeve and base. This is convenient and quick, improves work efficiency, and the sealing ring 104 improves the sealing effect, prevents internal gas leakage and extends service life.

[0018] In this embodiment, the specific implementation scenario is as follows: In actual use, when the GIS sleeve base is put into use, the sleeve body 2 is inserted into the interior of the connecting pipe 102, and then the sleeve body 2 is fixed to the base body 1 through the second flange 103, the sealing ring 104 and the third flange 201. The receiving block 3 is installed through the mounting block 301 and the mounting hole 302. The installation is convenient and quick, improving work efficiency. The sealing ring 104 improves the sealing effect, prevents internal gas leakage, and extends the service life. If the GIS sleeve base encounters a collision, the base body 1 descends, thereby driving the fixing block 105 to descend in the second buffer groove 303, thereby pressing down the spring damper 304. The spring damper 304 rebounds the force, thereby playing a buffering role. The elasticity of the sealing pad 4 provides a buffer zone for direct contact between the base body 1 and the receiving block 3, avoiding direct contact and collision damage, thereby preventing the GIS sleeve base from being damaged by collision and extending its service life. Compared with the existing GIS sleeve base, this utility model can improve the overall practicality of the GIS sleeve base through design.
