Ultra-long casting shell structure capable of improving bearing strength

Abstract

The utility model relates to a super-long casting shell structure capable of improving bearing strength. The super-long casting shell structure is characterized by comprising a casting shell, a plurality of reinforcing ribs are arranged on the outer contour of the casting shell, so that the situation that the strength cannot meet the design pressure after the size of the shell structure in the high-voltage electrical equipment is increased is met, and the problem that the pressure bearing requirement is not up to the standard is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of castings, in particular to an ultra-long casting shell structure with improved pressure-bearing strength. Background Art

[0002] As the internal filling gas of high-voltage electrical equipment shifts from sulfur hexafluoride to more environmentally friendly air, the design pressure requirements for pressure vessels are increasing, and the volume is also increasing. To meet these new pressure requirements, conventional shell structures do not have reinforcing ribs on the outer contour. As the volume increases, they cannot meet the pressure requirements. Therefore, a new shell structure is needed to withstand the increased design pressure requirements. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide an ultra-long cast shell structure with improved pressure-bearing strength, which can solve the problem that when traditional high-voltage electrical equipment castings use air as the insulating gas, the volume of the equipment needs to be increased accordingly, resulting in the equipment shell strength being difficult to meet the design pressure requirements.

[0004] In order to solve the above technical problems, the technical solution of the present utility model is: an ultra-long casting shell structure with improved pressure bearing strength, the innovation of which is: comprising a casting shell;

[0005] The casting shell is a cylindrical structure, and flanges are cast on both ends of the casting shell; a waist-shaped protrusion is provided near the top of the outer contour of the casting shell; a square protrusion is provided near the bottom of the outer contour of the casting shell;

[0006] A plurality of annular reinforcing ribs are provided in a ring shape between the waist-shaped protrusion and the square protrusion on the outer contour of the casting shell.

[0007] Furthermore, there are two annular reinforcement ribs, and the two annular reinforcement ribs divide the entire casting shell into three parts of equal length.

[0008] The advantages of the present invention are:

[0009] 1) In the present invention, a plurality of reinforcing ribs are provided on the outer contour of the cast shell to meet the situation where the shell structure of the high-voltage electrical equipment cannot meet the design pressure after the volume is increased, thereby avoiding the problem of substandard pressure requirements.

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0015] like Figure 2 An extra-long casting shell structure with improved pressure-bearing strength is shown, comprising a casting shell 1 .

[0016] The casting shell 1 is a cylindrical structure, with flanges cast on both ends of the casting shell; a waist-shaped protrusion 11 is provided near the top of the outer contour of the casting shell; a square protrusion 12 is provided near the bottom of the outer contour of the casting shell.

[0017] A plurality of annular reinforcing ribs 13 are provided in a ring shape on the outer contour of the casting shell 1 between the waist-shaped protrusion and the square protrusion.

[0018] There are two annular reinforcement ribs 13 , and the two annular reinforcement ribs 13 divide the entire casting shell 1 into three parts of equal length.

[0019] The working principle of the utility model is: by arranging a plurality of reinforcing ribs on the outer contour of the cast shell, the problem of the shell structure in the high-voltage electrical equipment being unable to meet the design pressure after the volume is increased is solved, thereby avoiding the problem of substandard pressure requirements.
