Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Fig. 1 is a schematic view of the present invention in an installed state; fig. 2 is an exploded view of the present invention.
As shown in fig. 1 and 2, the present invention can be divided into a pressing plate 1, a transparent flange 2 and an aluminum ring 3; and a seal ring 4. The utility model discloses install transom box window 91 department at gas insulated switchgear 9. Correspondingly, a switch contact is arranged below the air box window 91.
The outermost end of the utility model is a pressing plate 1, and the pressing plate 1 is made of stainless steel; the middle part of the pressing plate 1 is provided with a cavity as a pressing plate observation window 11; the pressing plate 1 is provided with a screw hole, and a screw is arranged in the screw hole to fixedly install the pressing plate 1 and the gas insulation switch cabinet 9 together; and a washer is sleeved outside the screw.
Below the pressure plate 1 is a transparent flange 2. The transparent flange 2 is preferably made of organic glass, but may be made of inorganic glass or other transparent materials. The transparent flange 2 is divided into three parts, namely a transparent plate 21 in the middle, an annular edge 22 at the periphery of the transparent plate 21 and a blind hole edge 23 below the transparent plate 21.
The area of the transparent plate 21 is larger than or equal to the area of the pressing plate observation window 11 of the stainless steel pressing plate 1. The diameter of the annular rim 22 is smaller than the diameter of the stainless steel pressure plate 1. The inner diameter of the blind hole edge 23 is equal to the inner diameter of the platen viewing window 11. The blind hole edge 23 is perpendicular to the transparent plate 21 and the annular rim 22. The thickness of transparent plate 21 and annular edge 22 is the same, and is less than the degree of depth of through-hole 32 on the aluminium ring 3, and this kind of setting is effectively avoided organic glass to be flattened and the fracture, bears the dynamics of pressurized all by aluminium ring 3.
The aluminum ring 3 is made of aluminum. The middle part of the aluminum ring 3 is provided with a through hole; the through hole is divided into an upper through hole 32 and a lower through hole 33. The diameter of the upper through hole 32 is equal to or greater than the outer diameter of the annular rim 22, so that the transparent flange 2 can be nested in the aluminum ring 3. The diameter of the lower through-hole 33 is larger than the outer diameter of the blind hole edge 23, so that an annular gap is formed between the lower through-hole 33 and the blind hole edge 23. A sealing ring 4 is arranged in the gap; the sealing ring 4 is made of compressible material, such as rubber.
The upper surface of the aluminum ring 3 is connected to the platen 1 to receive pressure from the platen 1. The lower surface of the aluminum ring 3 is connected with a gas insulated switchgear 9.
The mounted state is shown in fig. 1, in which the pressing plate 1, the transparent flange 2, the aluminum ring 3, the gasket 4, and the air box window 91 have the same axis. The blind hole edge 23 of the transparent flange 2 partially protrudes into the interior of the gas-insulated switchgear cabinet 9. The sealing ring 4 is arranged in an annular gap formed between the lower through hole 33 and the blind hole edge 23 and is compressed, and the compression amount of the sealing ring 4 is about 30 percent, so that the sealing performance is ensured.
In order to prevent the stainless steel pressing plate 1 from over-stressing or unevenly stressing the aluminum ring 3, each screw arranged at the bottom of the stainless steel pressing plate 1 is accompanied with a gasket with the same height as the aluminum ring 3, and the whole stress is balanced.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
