[0056] The installation process of the high-voltage combined electrical GIS assembly docking cabin in the embodiment of the present application is as follows:

[0057] 1. Installation of base components:

[0058] First, select a suitable installation location and splice the base unit block 21 according to the ground conditions to ensure that the entire base assembly 2 is stably fixed; then fix the bottom flange 111 of the vertical column 11 to the base unit block 21 with bolts to ensure the basic stability of the overall frame.

[0059] 2. Assembly of metal frame:

[0060] The horizontal cross bars 12 are sequentially connected between the vertical columns 11 through the connectors 13 to form a square frame structure, and then the connectors 13 are fixed with bolts to ensure that the entire frame is firm.

[0061] Exposed keels 14 are installed in the front, back, left and right directions of the frame to provide a support structure for the subsequent installation of wall panels.

[0062] 3. Installation of wall panel components:

[0063] Align the metal wall panels 31 with the buckle assembly on the exposed keel 14, insert them into the slots and secure them with the rubber washers. Each metal wall panel 31 can be installed and removed independently, ensuring a simple and efficient installation process.

[0064] 4. Installation of top protective cover:

[0065] Align the top protective cover 4 with the top position of the metal frame 1 and fix it with bolts. Since the top protective cover 4 has a double slope structure, the drainage performance of the top protective cover 4 is improved, thereby reducing the accumulation of rainwater.

[0066] 5. Installation of adjustable working platform:

[0067] The slide rail 52 is mounted on the vertical column 11 in the metal frame 1. The work platform 51 is mounted on the slide rail 52, ensuring that it can slide freely along the slide rail 52 and is fixed by the locking device 53.

[0068] 6. Installation of sealing components:

[0069] A sealing assembly 6 is installed at the hatch entrance 141 , and the flexible sealing curtain 61 is fixed to the metal wall panel 31 through a guide rail 62 to ensure a sealing effect of the hatch entrance 141 .

[0070] 7. Installation of lifting scaffolding platform components:

[0071] The lifting scaffolding platform assembly 7 is installed around the metal frame 1 and connected to the metal frame 1 through a sliding mechanism 71. An electric winch 711 and a steel cable 712 are installed to ensure that the scaffolding can be adjusted in height to meet the needs of high-altitude operations.

[0072] 8. Installation of fresh air air conditioning system:

[0073] Finally, install the fresh air air conditioning system at the appropriate location in the docking cabin and connect the air supply duct to ensure that the filtration and regulation functions of the air in the cabin operate normally.

[0074] Through the above-mentioned installation steps, the docking cabin of the embodiment of the present application can quickly complete the on-site installation, meet the safety protection requirements of high-voltage electrical equipment, and at the same time ensure the convenience and flexibility of operation.

[0075] In some embodiments, the flexible sealing curtain 61 has a double-layer composite structure, comprising an inner layer of wear-resistant rubber material and an outer layer of fire-resistant material, bonded together to form a single unit. This double-layer composite structure provides dual protection: the inner layer of wear-resistant rubber enhances the curtain's durability and impact resistance, while the outer layer of fire-resistant material provides effective flame retardant protection in emergencies such as fire.

[0076] In some embodiments, the wear-resistant rubber material layer is a chloroprene rubber layer, and the fireproof material layer is a silicone rubber-coated glass fiber cloth.

[0077] Neoprene offers excellent wear and weather resistance. Using this layer as the wear-resistant rubber material makes it suitable for use in harsh environments. The silicone rubber-coated fiberglass fabric offers excellent flame retardancy and high-temperature resistance, further enhancing the curtain's protective function. Through careful material selection, this sealed curtain is well-suited to diverse environmental conditions, particularly those requiring high temperatures and high pressures, ensuring efficient operation of the entire docking bay even in these challenging conditions.

[0078] In some embodiments, a shock-absorbing pad is provided at the bottom of the base unit block 21. The provision of the shock-absorbing pad can absorb vibrations transmitted from the ground, reduce the impact of vibrations transmitted to the GIS equipment, ensure stable operation of the equipment, and improve equipment reliability, especially in situations where the ground is uneven or there is a vibration source.

[0079] In order to enhance the overall stability of the base assembly 2, a horizontal reinforcing plate 22 is optionally provided above the entire base assembly 2. The horizontal reinforcing plate 22 can be made of a higher-strength steel plate or a galvanized steel plate to ensure sufficient bending and compression resistance, thereby providing reliable support and stability. In order to reduce the deadweight, the thickness of the horizontal reinforcing plate 22 can be selected according to the load-bearing requirements, usually 8-12 mm. The size of the horizontal reinforcing plate 22 should cover the area of ​​the entire base assembly 2, and the edge of the horizontal reinforcing plate 22 needs to be flush with the edge of the base unit block 21 on the side. The horizontal reinforcing plate 22 is fixed to the top of the base unit block 21 by bolting. Bolt holes are reserved on each base unit block 21 and the corresponding horizontal reinforcing plate 22. The horizontal reinforcing plate 22 is fastened to the base unit block 21 by bolts, so that all base unit blocks 21 can be firmly combined into a whole. In order to increase the rigidity of the overall structure, a grid-like reinforcement rib 231 can also be arranged on the bottom surface of the horizontal reinforcement plate 22. These reinforcement ribs 231 can be welded to the bottom surface of the horizontal reinforcement plate 22 in the transverse and longitudinal directions to form a mesh structure. The mesh structure can be consistent with the distribution of the base unit block 21, so that the reinforcement rib 231 is just in the connection position between adjacent base unit blocks 21. Accordingly, the upper surface of the base unit block 21 is provided with a groove for embedding the reinforcement rib 231, so that the reinforcement rib 231 of the mesh structure is just embedded in the groove, further improving the bending and torsional resistance of the overall structure.

[0080] In some embodiments, the connector 13 includes a connecting column 131 that is threadedly connected to the top of the vertical column 11. The column body of the connecting column 131 is provided with two horizontal clamps 132 at a 90° angle. The end side of the clamp 132 is provided with a horizontal connecting groove 1321. The ends of the horizontal crossbar 12 are respectively provided with a plug 121 for plugging the clamp 132. The clamp 132 is adapted to the shape of the connecting groove 1321, and the clamp 132 and the plug 121 are provided with interconnecting screw holes and are connected by bolts. In this embodiment, the connecting member 13 is threadedly connected to the top of the vertical column 11 and has two horizontal clamps 132 at a 90° angle. After use, the connection between the horizontal crossbar 12 and the vertical column 11 is more stable, improving the stability of the overall frame structure. Moreover, 132 can be quickly assembled and disassembled by the arrangement of the clamp 132 and the plug 121, reducing the labor intensity during construction and making installation more flexible and convenient.

[0081] The method for using the high-voltage combined electrical GIS assembling docking compartment in the embodiment of the present application is as follows:

[0082] 1. Preparation:

[0090] 5. High-altitude work support:

[0091] For maintenance outside the cabin, a lifting scaffolding platform assembly 7 allows operators to access a suitable high-altitude maintenance area outside the cabin. Electric winches 711 control the raising and lowering of steel cables 712 to adjust the scaffolding platform to a suitable height. Operators can use the scaffolding to perform high-altitude maintenance and commissioning work, ensuring safe and efficient completion of operations.

[0092] 6. Equipment inspection and maintenance:

[0093] Operators can remove portions of the metal wall panels 31 to facilitate overhaul or replacement of the GIS equipment as needed for overhaul or maintenance. Using snap-fit ​​assemblies and rubber washers on the exposed keel 14, the metal wall panels 31 can be quickly removed for maintenance and then quickly restored.

[0094] 7. Check and restore:

[0095] After the maintenance operation is completed, the removed metal wall panels 31 are reinstalled to ensure that they are properly connected.
