Embodiment Construction

[0039] see figure 1 and figure 2As shown, the seven-circuit load switch inflatable cabinet of the present invention includes a stainless steel gas tank 1 . Gas box 1 is formed by bolt connection and welding by front plate 31, rear plate 32, two side plates 33 and top plate 34 of symmetrical shape. The wall thickness of the gas box 1 is 3mm. Also can do thicker, be arranged with seven load switches 2 that are in-line arrangement in the gas box 1.

[0040] combine figure 1 , image 3 and Figure 4 As shown, the front plate 31 of the air box 1 is integrally formed by a first front plate 35 , an inverse L-shaped connecting plate 36 folded inward and a bottom plate 37 . Three first observation windows 5 through which the working state of a load switch 2 can be observed are installed on the first front panel 35 corresponding to the position of each load switch 2 . The first observation window 5 is made of PC material. A vertical first reinforcing rib 38 is respectively weld...

Abstract

The invention relates to a seven-loop load switch inflatable cabinet, belonging to the technical field of gas insulation switching devices. The seven-loop load switch inflatable cabinet comprises a stainless steel gas tank, wherein wall thickness of the gas tank is 3mm, the gas tank is internally provided with seven load switches, the gas tank is formed by connecting a front plate, a rear plate, two side plates shapes of which are in bilateral symmetry and a top plate, the front plate is composed of a first front plate, an inverted L-shaped connecting plate which bends inward and a base plate, the inner sides of the front plate and the rear plate, the inner sides of the two side plates and the inner side of the top plate are respectively provided with a plurality of reinforcing ribs, and the seven load switches are arranged in the gas tank at linear intervals from left to right. The seven-loop load switch inflatable cabinet disclosed by the invention has the advantages that structural strength of the gas tank is high, and seven load switches can be arranged in the gas tank.

Description

technical field [0001] The invention relates to a gas-insulated switchgear, in particular to a gas-filled cabinet for a seven-circuit load switch. Background technique [0002] The load switch inflatable cabinet includes an air box and several load switches installed in the air box. The existing load switch inflatable cabinets include 4-circuit load switch inflatable cabinets, 5-circuit load switch inflatable cabinets and 6-circuit load switch inflatable cabinets. [0003] The gas boxes of these existing load switch gas cabinets are all made of stainless steel. The thickness of the gas box with built-in 4-circuit load switch is 2mm; the thickness of the gas box with built-in 6-circuit load switch is 3mm. The structure of the stainless steel air box determines the number of circuits, because if the structural strength of the air box is not strong enough, the stainless steel air box will be deformed during the process of vacuuming and inflating the inflatable cabinet, and th...
