[0023] Reference Figure 1 , Figure 2 and Figure 3 GIS shell is a kind of shell specially used to protect GIS equipment. Its main function is to protect the equipment from interference and damage from the external environment. Most of the GIS shells are directly connected to the outside of the GIS equipment during installation. During later maintenance and replacement, the whole needs to be dismantled for operation, which is cumbersome and complicated. The second shell 106 is connected to the first shell 101 by a plug-in strip 105. The flange covers 104 at the upper and lower ends of the first shell 101 and the second shell 106 are locked by bolts. The upper and lower connecting ring plates 102 and pull plates 103 on the outside of the first shell 101 and the second shell 106 are locked by bolts to form an installation structure in which the GIS shell can be unfolded as a whole. While ensuring the overall stability, it is convenient for assembly and later disassembly and maintenance, which improves the overall practicality and makes the later maintenance operation more convenient.

[0024] Reference Figure 1-Figure 4 The first inner limit plate 2 and the second inner limit plate 3 are snap-fitted into the inside of the first shell 101 and the second shell 106. The second inner limit plate 3 is provided with a plug-in hole plugged into the plug-in column 202. The plug-in slot 201 and the plug-in strip 105 are snap-fitted, and the clamping sleeve 301 and the GIS equipment are snap-fitted, forming a limiting structure inside the GIS shell, making the installation of the GIS equipment more stable. The first inner limit plate 2 and the second inner limit plate 3 are a combined structure, which is convenient for replacement and maintenance after unfolding.

[0025] Working principle: The second shell 106 of the GIS shell with an integrally deployable installation structure is connected to the first shell 101 by a plug-in strip 105, the flange covers 104 at the upper and lower ends of the first shell 101 and the second shell 106 are locked by bolts, and the upper and lower connecting ring plates 102 and the pull plates 103 of the first shell 101 and the second shell 106 are locked by bolts, forming an integrally deployable installation structure of the GIS shell. While ensuring overall stability, it is convenient for assembly, later disassembly and maintenance, and improves the overall practicality. The later maintenance operation of Shedie is more convenient. The first inner limit plate 2 and the second inner limit plate 3 are clamped in the first shell 101 and the second shell 106. The second inner limit plate 3 is provided with a plug-in hole plugged with the plug-in column 202. The plug-in slot 201 and the plug-in strip 105 are connected by clamping, and the clamping sleeve 301 and the GIS equipment are connected by clamping, so as to form a limiting structure inside the GIS shell, which makes the installation of GIS equipment more stable.
