Figure 1a The gas insulated switchgear 100 of the utility model is shown by way of example, which comprises a cabinet 20 and a gas tank 10 arranged on the longitudinal side of the cabinet 20, so that the lateral dimension of the gas tank 10 is arranged to be no more than the lateral dimension of the cabinet 20, preferably aligned with the lateral dimension of the cabinet 20, so that the lateral deformation of the gas insulated switchgear 100 can be reduced by reducing the lateral deformation of the gas tank 10, thereby avoiding affecting the lateral arrangement of the gas insulated switchgear 100 and other switchgears. It should be noted that the "lateral direction" described herein is the left-right direction shown in FIG. 1, the "vertical direction" is the up-down direction shown in FIG. 1, and the "longitudinal direction" is the front-rear direction shown in FIG. 1. In addition, the "inner side" described herein refers to the side facing the internal insulation gas of the gas tank 10, and the "outer side" refers to the side facing the external atmospheric environment. Figure 1a The gas insulated switchgear 100 of the utility model is shown by way of example, which comprises a cabinet 20 and a gas tank 10 arranged on the longitudinal side of the cabinet 20, so that the lateral dimension of the gas tank 10 is arranged to be no more than the lateral dimension of the cabinet 20, preferably aligned with the lateral dimension of the cabinet 20, so that the lateral deformation of the gas insulated switchgear 100 can be reduced by reducing the lateral deformation of the gas tank 10, thereby avoiding affecting the lateral arrangement of the gas insulated switchgear 100 and other switchgears. It should be noted that the "lateral direction" described herein is the left-right direction shown in FIG. 1, the "vertical direction" is the up-down direction shown in FIG. 1, and the "longitudinal direction" is the front-rear direction shown in FIG. 1. In addition, the "inner side" described herein refers to the side facing the internal insulation gas of the gas tank 10, and the "outer side" refers to the side facing the external atmospheric environment.

[0036] As shown in FIG. 1, the gas tank 10 can comprise a first side plate 11, a second side plate 12, a first reinforcing member 111, and a second reinforcing member 121. Figures 1a to 3b

[0037] Specifically, the first side plate 11 can be configured as the left side plate of the gas tank 10, and the second side plate 12 can be configured as the right side plate of the gas tank 10, both of which extend in the vertical direction and are arranged spaced apart relative to each other in the lateral direction, so as to cooperatively define the lateral dimension of the gas tank 10. The first side plate 11 can be divided into a first connecting region 11a and a first reinforcing region 11b in the vertical direction, the first connecting region 11a can be convex inward relative to the first reinforcing region 11b and transitioned obliquely with the first reinforcing region 11b, towards the second side plate 12. Correspondingly, the second side plate 12 can be divided into a second connecting region 12a and a second reinforcing region 12b in the vertical direction, the second connecting region 12a can be arranged opposite to the first connecting region 11a, and convex inward relative to the second reinforcing region 12b and transitioned obliquely with the second reinforcing region 12b, towards the first side plate 11.

[0038] Thus, the lateral dimension of the first connecting region 11a to the second connecting region 12a is smaller than that of the first reinforcing region 11b to the second reinforcing region 12b, so that the first connecting region 11a has a greater lateral outward deformability than the first reinforcing region 11b, and the second connecting region 12a has a greater lateral outward deformability than the second reinforcing region 12b, thereby allowing the electrical components such as bus couplers that can cause greater lateral outward deformation of the gas tank 10 to be installed between the first connecting region 11a and the second connecting region 12a, without excessively increasing the lateral dimension of the gas tank 10.

[0039] ​Further, at least one first reinforcing member 111 extending in the longitudinal direction can be arranged on the side of the first reinforcing area 11b of the first side plate 11, and at least one second reinforcing member 121 extending in the longitudinal direction can be arranged on the side of the second reinforcing area 12b of the second side plate 12. This not only makes the air tank 10 more beautiful, but also reduces the lateral outward deformation of the first reinforcing area 11b of the first side plate 11 and the second reinforcing area 12b of the second side plate 12 under the internal pressure of the air tank 10, such as 0.02 MPa, thereby avoiding excessive increase in the lateral dimension of the air tank 10. The arrangement pattern of the first reinforcing member 111 on the first reinforcing area 11b can be the same as or different from the arrangement pattern of the second reinforcing member 121 on the second reinforcing area 12b.

[0040] Optionally, as shown in FIGS. 1 to 3, the first reinforcing member 111 can be designed as four first reinforcing members 111 arranged vertically spaced apart, and the second reinforcing member 121 can be designed as four second reinforcing members 121 arranged vertically spaced apart. Figure 4 and Figure 5 As shown in FIG. 3, the spacing between adjacent first reinforcing members 111 and the spacing between adjacent second reinforcing members 121 can be designed to be between 110 mm and 170 mm, and the spacing between adjacent first reinforcing members 111 and the spacing between adjacent second reinforcing members 121 can be the same or different. In an embodiment not shown, the number of first reinforcing members 111 and second reinforcing members 121 can be two, three or more than four, and the number of the two can be different.

[0041] Further, the first reinforcing member 111 is arranged inwardly relative to the first reinforcing area 11b, wherein the spacing between the longitudinal end of the first reinforcing member 111 and the longitudinal end side of the adjacent first reinforcing area 11b is preferably designed to be 20 mm. As shown in FIG. 3, the front ends of the four first reinforcing members 111 are aligned, and the rear ends of the first reinforcing members 111 can be appropriately shortened to avoid interference with the components inside the air tank 10. It can be understood that the arrangement of the second reinforcing member 121 on the second reinforcing area 12b can be basically the same as the arrangement of the first reinforcing member 111 on the first reinforcing area 11b, and thus will not be described again. Figure 4

[0042] Optionally, with reference to FIGS. 1 to 3, the first reinforcing member 111 can be designed as four first reinforcing members 111 arranged vertically spaced apart, and the second reinforcing member 121 can be designed as four second reinforcing members 121 arranged vertically spaced apart. Figure 3b ​The periphery of the first side plate 11 is provided with a first flange 11c extending outwardly away from the second side plate 12, which is used to connect to the third side plate 14, the fourth side plate 15, the fifth side plate 16 and the sixth side plate 17 described later and align with the left end side of the cabinet body 20 of the gas insulated switchgear 100, so as to allow the first side plate 11 including the first connecting area 11a and the first reinforcing area 11b to be able to deform laterally outwardly to the left end side of the first flange 11c. In the case where the lateral extension length of the first flange 11c is designed to be 6 mm, the maximum lateral outward deformability of the first reinforcing area 11b of the first side plate 11 is 6 mm, and the maximum lateral outward deformability of the first connecting area 11a of the first side plate 11 is more than 6 mm.

[0043] Similarly, the periphery of the second side plate 12 can be provided with a second flange 12c extending outwardly away from the first side plate 11, and the arrangement of the second flange 12c on the second side plate 12 can be substantially the same as that of the first flange 11c on the first side plate 11, and thus will not be described again.

[0044] Optionally, in combination with Figure 4 and Figure 5 As shown, the first reinforcing member 111 and the second reinforcing member 121 can be fixed to the corresponding side plate via a plurality of longitudinally spaced connecting structures 13, which are intermittently welded to the corresponding side plate in the manner of argon arc welding or laser welding, so as to facilitate the operation of construction personnel and reduce the welding deformation. Preferably, for a single first reinforcing member 111 or a single second reinforcing member 121, the longitudinal dimension such as the length of a welding bead of a single connecting structure 13 can be designed to be 50 mm, and the longitudinal spacing such as the welding bead spacing between adjacent connecting structures 13 can be designed to be between 120 mm and 135 mm.

[0045] Optionally, in combination with Figure 6 and Figure 7 As shown, the third side plate 14 can be configured as the front side plate of the gas tank 10, and the fourth side plate 15 can be configured as the rear side plate of the gas tank 10, both of which extend vertically and are spaced apart relative to each other in the longitudinal direction. Among them, the third side plate 14 can be connected to the front side of the first flange 11c of the first side plate 11 and the front side of the second flange 12c of the second side plate 12, and the fourth side plate 15 can be connected to the rear side of the first flange 11c of the first side plate 11 and the rear side of the second flange 12c of the second side plate 12.

[0046] Preferably, the side plate of the third side plate 14 facing away from the fourth side plate 15, i.e. the outer side, can be arranged with a support component 141, which on the one hand can improve the strength of the third side plate 14 so as to reduce the deformation of the third side plate 14, and on the other hand can be mounted to the cabinet body 20 of the gas insulated switchgear 100 via the support component 141. The side of the fourth side plate 15 facing the third side plate 14, i.e. the inner side, can be arranged with a third reinforcing member 151 extending in the transverse direction, which not only can ensure the external appearance of the gas tank 10, but also can reduce the deformation of the fourth side plate 15.

[0047] Exemplarily, as shown in Figure 7 , two third reinforcing members 151 can be arranged on the inner side of the fourth side plate 15 in the vertical direction, and the third reinforcing members 151 can also be fixed to the corresponding side plate via a plurality of connecting structures 13 distributed in the longitudinal direction.

[0048] Optionally, in combination with Figure 6 , the support component 141 can include a first support member 141a, a second support member 141b and a third support member 141c. The first support member 141a and the second support member 141b can extend in the transverse direction and be arranged in the vertical direction relative to each other, and the third support member 141c extending in the vertical direction can connect the first support member 141a and the second support member 141b together, so as to greatly improve the stress distribution on the third side plate 14. Referring to Figure 6 , the transverse dimension of the second support member 141b can be shortened relative to the transverse dimension of the first support member 141a, so as to avoid the relevant components arranged on the gas insulated switchgear 100.

[0049] Optionally, in combination with Figure 8 and Figure 9 , the fifth side plate 16 can be configured as the top side plate of the gas tank 10, and the sixth side plate 17 can be configured as the bottom side plate of the gas tank 10, both of which can extend in the vertical direction and be arranged in the vertical direction relative to each other. Among them, the fifth side plate 16 can be connected to the upper side of the first flange 11c of the first side plate 11 and the upper side of the second flange 12c of the second side plate 12, and the sixth side plate 17 can be connected to the lower side of the first flange 11c of the first side plate 11 and the lower side of the second flange 12c of the second side plate 12.

[0050] Preferably, the side of the fifth side plate 16 facing away from the sixth side plate 17, i.e. the outer side, can be arranged with a fourth reinforcing member 161, which can extend in the transverse direction to reduce the deformation of the fifth side plate 16. The side of the sixth side plate 17 facing away from the fifth side plate 16, i.e. the outer side, can be arranged with a fifth reinforcing member 171, which also extends in the transverse direction to reduce the deformation of the sixth side plate 17.

[0051] Optionally, the gas tank 10 has a good insulation environment due to the filling of insulating gas, and therefore the first reinforcing member 111, the second reinforcing member 121 and the third reinforcing member 151 arranged inside the gas tank 10 can be configured as a square tube profile made of Q235 steel, which is not only low in cost but also easy to manufacture. For example, the square tube profile can be designed to have a height of 15 mm, a width of 30 mm and a thickness of 2 mm, and is welded to the corresponding side plate in the width plane.

[0052] In view of the need for long-term contact with the external atmospheric environment, the first side plate 11, the second side plate 12, the third side plate 14, the fourth side plate 15, the fifth side plate 16 and the sixth side plate 17 can be made of stainless steel material and welded into shape. For example, the thickness of the first side plate 11 and the second side plate 12 can be designed to be 2.5 mm, and the thickness of the fifth side plate 16 can be designed to be 3 mm. In addition, the first support member 141a, the second support member 141b, the third support member 141c, the fourth reinforcing member 161 and the fifth reinforcing member 171 can be configured as U-shaped profiles made of stainless steel, and each member is welded to the corresponding side plate through the respective U-shaped leg.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
