Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0033] Figure 1 This application shows a front view of the GIS cover plate. Figure 2 This application shows Figure 1 A cross-sectional view of the GIS cover plate, based on Figures 1 to 2 As shown, this application provides a GIS cover plate 100 for assembling GIS equipment. The GIS cover plate includes a cover plate body 110 and a sealing flange 120. The surface of the cover plate body 110 has an irregular arc shape. The sealing flange 120 is located at the edge of the cover plate body 110 and is suitable for fixed connection with the flange of the GIS housing 130. The surface of the cover plate body 110 is provided with multiple component mounting surfaces 140. The multiple component mounting surfaces 140 are located at different positions on the surface of the cover plate body 110, and the shapes of the multiple component mounting surfaces 140 are not exactly the same, so that the component mounting surfaces 140 are suitable for installing different components required for GIS equipment.

[0034] This application's GIS cover plate features multiple component mounting surfaces located at different positions on its surface. During GIS equipment assembly, the required components can be selected based on the specific needs of the GIS equipment and installed on the appropriate mounting surfaces on the cover plate. This allows the GIS cover plate to be customized to meet specific requirements, overcoming the limitation of conventional GIS cover plates that can only accommodate one type of GIS equipment component. Furthermore, the shapes of the mounting surfaces are not identical, allowing for the selection of matching mounting surfaces for specific components, thus enabling the installation of different components on the GIS cover plate according to specific needs.

[0035] In one possible implementation, see [link to relevant documentation] Figures 3 to 4 As shown, the component mounting surface 140 includes an adsorbent component mounting surface 150 suitable for mounting the adsorbent component. The adsorbent component mounting surface 150 has an adsorbent component vent hole 151 and an adsorbent component threaded mounting hole 152. The adsorbent component vent hole 151 is located in the middle of the adsorbent component mounting surface 150, and the adsorbent component threaded mounting hole 152 is located around the adsorbent component vent hole 151 and corresponds one-to-one with the adsorbent component mounting hole.

[0036] It should be noted that when the GIS equipment requires the assembly of adsorbent components, firstly, an adsorbent component vent hole 151 and an adsorbent component threaded mounting hole 152 are machined on the adsorbent component mounting surface 150. Then, the adsorbent component is placed into the vent hole 151, and the mounting hole of the adsorbent component is aligned with the adsorbent component threaded mounting hole 152 on the adsorbent component mounting surface 150. A bolt is then threaded through the mounting hole of the adsorbent component and then installed on the cover plate through the threaded mounting hole 152. This allows the adsorbent component to be installed on the cover plate when the GIS equipment requires the assembly of adsorbent components.

[0037] It should also be noted that in this application, the adsorbent assembly is installed at the adsorbent assembly mounting surface 150 on the surface of the cover plate. Compared with the traditional method of embedding the adsorbent assembly, this application sets the adsorbent assembly at the adsorbent assembly mounting surface on the surface of the cover plate, which can effectively reduce the height of the arc-shaped cover plate, reduce the weight of the cover plate, and save material costs.

[0038] In one possible implementation, see [link to relevant documentation] Figures 3 to 4As shown, the component mounting surface 140 also includes an inflation valve assembly mounting surface 160 suitable for mounting the inflation valve assembly; the inflation valve assembly mounting surface 160 has an inflation valve assembly vent hole 161 and an inflation valve assembly threaded mounting hole 162. The inflation valve assembly vent hole 161 is located in the middle of the inflation valve assembly mounting surface 160, and the inflation valve assembly threaded mounting hole 162 is arranged around the inflation valve assembly vent hole 161 and corresponds one-to-one with the mounting hole of the inflation valve assembly.

[0039] It should be noted that when there is a need to assemble an inflation valve assembly in GIS equipment, firstly, an inflation valve assembly vent hole 161 and an inflation valve assembly threaded mounting hole 162 are machined on the inflation valve assembly mounting surface 160. Then, the inflation valve assembly is placed at the inflation valve assembly vent hole 161, and the mounting hole of the inflation valve assembly is aligned with the inflation valve assembly threaded mounting hole 162 on the inflation valve assembly mounting surface 160. Bolts are then passed through the mounting hole of the inflation valve assembly and the inflation valve assembly threaded mounting hole 162 on the inflation valve assembly mounting surface 160 to form a spiral connection, so that the inflation valve assembly can be installed on the inflation valve assembly mounting surface of the GIS cover plate when there is a need to assemble the inflation valve assembly in GIS equipment.

[0040] In one possible implementation, see [link to relevant documentation] Figures 5 to 6 As shown, the component mounting surface 140 also includes a blast-proof diaphragm assembly mounting surface 170 suitable for mounting the blast-proof diaphragm assembly. The blast-proof diaphragm assembly mounting surface 170 also has a blast-proof diaphragm assembly vent hole 171 and a blast-proof diaphragm assembly threaded mounting hole 172. The blast-proof diaphragm assembly vent hole 171 is located at the center of the blast-proof diaphragm assembly mounting surface 170, and the blast-proof diaphragm assembly threaded mounting hole 172 is arranged around the blast-proof diaphragm assembly vent hole 171 and corresponds one-to-one with the blast-proof diaphragm assembly mounting hole.

[0041] It should be noted that when there is a need to assemble explosion-proof components into GIS equipment, a vent hole 171 and a threaded mounting hole 172 for the explosion-proof component are machined on the mounting surface 170. The explosion-proof component is then placed at the vent hole 171, and the mounting hole and threaded mounting hole 172 are aligned. Bolts are then passed through the mounting holes and screwed onto the cover plate via the threaded mounting holes 172. This allows the explosion-proof component to be installed on the GIS cover plate when assembly of the GIS equipment is required.

[0042] In one possible implementation, a double-seal groove 173 is also provided on the mounting surface of the explosion-proof disc assembly. The double-seal groove 173 is located between the vent hole 171 and the threaded mounting hole 172 of the explosion-proof disc assembly, and is suitable for pipeline sealing, which can effectively improve the airtightness of GIS equipment. A sealing ring is also provided within the double-seal groove 173.

[0043] In one possible implementation, when installing the explosion-proof plate assembly on the cover plate 100, the sealing ring is first placed into the double sealing groove, and then the explosion-proof plate assembly is spirally installed, which can effectively improve the airtightness of the equipment.

[0044] It should also be noted that when the adsorbent assembly, inflation valve assembly, and explosion-proof plate assembly need to be replaced, each assembly only needs to be removed from the cover plate, and the new assembly can be installed on the original mounting surface. This process does not require the entire cover plate to be removed from the equipment, which effectively reduces replacement time and labor intensity and facilitates operation.

[0045] It should also be noted here that the GIS cover plate 100 of this application is used for assembling GIS equipment, see [link to relevant documentation]. Figure 1 As shown, when there is no component installation requirement for the GIS equipment, the GIS cover plate 100 is directly installed on the housing 130 of the GIS equipment. When there is a component installation requirement for the GIS equipment, the components are assembled on the component mounting surface 140 according to the specific requirements.

[0046] In one possible implementation, see [link to relevant documentation] Figures 3 to 4 As shown, when the GIS equipment has the installation requirement of assembling both an inflation valve assembly and an adsorbent assembly, the inflation valve assembly mounting surface 160 and the adsorbent assembly mounting surface 150 of the GIS cover plate 100 are machined and then installed on the inflation valve assembly mounting surface and the adsorbent assembly mounting surface of the GIS cover plate respectively according to the above-mentioned installation method of the inflation valve assembly and the adsorbent assembly, so as to meet the assembly requirement of assembling both the inflation valve assembly and the adsorbent assembly of the GIS equipment.

[0047] In one possible implementation, see [link to relevant documentation] Figures 5 to 6As shown, when the GIS equipment simultaneously requires the assembly of an inflation valve assembly, an adsorbent assembly, and an explosion-proof diaphragm assembly, the GIS cover plate 100, whose component mounting surface 140 is unprocessed, can be machined. Specifically, the adsorbent assembly mounting surface 150, the inflation valve assembly mounting surface 160, and the explosion-proof diaphragm assembly mounting surface 170 of the GIS cover plate can be machined respectively, and then each assembly can be installed on its corresponding mounting surface to meet the component installation requirements of the GIS equipment. Alternatively, following the above-mentioned installation method for the explosion-proof diaphragm assembly, the explosion-proof diaphragm assembly mounting surface 170 can be machined on the cover plate where the inflation valve assembly and adsorbent assembly are already installed, and then the explosion-proof diaphragm assembly can be installed to meet the installation requirements of the GIS equipment having an explosion-proof diaphragm assembly. The adsorbent assembly and the explosion-proof diaphragm assembly are designed separately.

[0048] It should be noted that after the components are installed according to the assembly requirements of the GIS equipment, the mounting surfaces of the GIS cover plate that have not yet been fitted with components can be specially processed according to specific usage requirements, so as to install other components required by the GIS equipment.

[0049] For example, according to the requirements of GIS equipment, it is necessary to install a partial discharge sensor for the partial discharge signal inside the GIS housing. At this time, the mounting surface of the GIS cover plate without the components installed is machined according to the installation requirements of the partial discharge sensor, and then the partial discharge sensor is installed to obtain a GIS cover plate equipped with the partial discharge sensor.

[0050] Furthermore, the GIS cover plate of this application has multiple component mounting surfaces. To meet different GIS equipment assembly requirements, the necessary components can be mounted on the cover plate after machining these mounting surfaces. Compared to traditional cover plates, which are first produced according to the GIS equipment requirements and then have the required components installed, this method requires different cover plate production molds to meet different component assembly needs. This results in higher production costs and significant limitations on cover plate versatility. In contrast, the cover plate of this application, with multiple component mounting surfaces, can be mass-produced using the same casting mold. The mounting surfaces are then machined according to different equipment component assembly requirements, allowing for the installation of different components. This GIS cover plate not only improves production efficiency but also effectively enhances the versatility of the GIS cover plate.

[0051] In one possible implementation, see [link to relevant documentation] Figures 1 to 6As shown, the flange face of the sealing flange 120 has a sealing groove 121, and a sealing ring is placed in the sealing groove. There are two sealing grooves 121, and the two sealing grooves 121 are arranged adjacent to each other. This application provides a double sealing groove 121 on the flange face of the sealing flange 120. Compared with the conventional single sealing groove design of the cover plate, the double sealing groove of this application can effectively improve the airtightness of GIS equipment.

[0052] When assembling the cover plate 100, after the sealing ring is placed into the sealing groove 121, the cover plate 100 and the housing 130 are detachably connected through the sealing flange of the cover plate 100 and the flange through hole of the housing 130.

[0053] In one possible implementation, the GIS cover plate of this application further includes a fastener 180, which is disposed within the through hole 122 of the sealing flange 120. The fastener 180 is suitable for connecting the GIS cover plate to the housing 130 of the GIS equipment. In another possible implementation, when connecting the GIS cover plate 100 to the GIS housing 130, the through hole 122 of the sealing flange 120 of the GIS cover plate is first aligned with the flange through hole of the GIS housing 130. Then, the fastener 180 passes through the through hole of the sealing flange 120 and the flange through hole of the GIS housing 130, and is screwed onto a nut to fix the GIS cover plate 100 onto the GIS housing 130, thus completing the assembly of the GIS equipment.

[0054] In one possible implementation, the GIS cover plate 100 is further provided with two lifting threaded holes 190, which are located between every two adjacent through holes of the sealing flange 120 and are positioned opposite each other along the central axis of the cover plate 100. The lifting threaded holes 190 are suitable for transferring the cover plate 100 to the cover plate installation position of the GIS housing 130 for assembly of the cover plate 100.

[0055] Therefore, this application provides a GIS cover plate for assembling GIS equipment. The cover plate includes a cover plate body 110 and a sealing flange 120. The surface of the cover plate body 110 has an irregular arc shape. The sealing flange 120 is located at the edge of the cover plate body 110 and is suitable for fixed connection with the flange of the GIS housing 130. The surface of the cover plate body 110 is provided with multiple component mounting surfaces 140, which are located at different positions on the surface of the cover plate body 110 and have different shapes, so that each component mounting surface 140 is suitable for installing different components required for GIS equipment. This application provides multiple component mounting surfaces of different shapes at different positions on the surface of the cover plate body of the GIS cover plate, allowing different components required for GIS equipment to be installed on these surfaces. In other words, the GIS cover plate of this application can install the components required for GIS equipment on the surface of the cover plate body according to the specific needs of various GIS equipment, thereby enabling the GIS cover plate to adapt to the different component assembly needs of various GIS equipment and perform corresponding component installation. This solves the problem that conventional GIS cover plates can only meet the assembly needs of one type of GIS equipment component.
