Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of GIS, specifically a gas insulation pipeline for GIS equipment. BACKGROUND

[0002] GIS is the abbreviation of gas insulated switchgear, and GIS equipment has been widely used in various fields with the continuous development of science and technology, and the GIS pipeline is a common GIS equipment pipeline, at present, when the GIS pipeline is used, the GIS pipeline is prone to deformation under pressure due to insufficient strength of the GIS pipeline itself. UTILITY MODEL CONTENT

[0003] The utility model aims at providing a gas insulation pipeline for GIS equipment to solve the problems in the above background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical scheme: a gas insulation pipeline for GIS equipment, which comprises a GIS pipeline composed of a GIS main pipe and a connecting pipe welded on the outer wall of the GIS main pipe, the inner wall of the connecting pipe and the inner wall of the GIS main pipe are communicated, first reinforcing rib arrays are welded in the GIS main pipe and the connecting pipe, second reinforcing rib arrays are welded on the outer wall of the GIS pipeline, the first reinforcing rib array is a helical first reinforcing rib, and the second reinforcing rib array is composed of reinforcing plates intersecting longitudinally and transversely.

[0005] Further, the second reinforcing rib array further comprises a second reinforcing rib integrally arranged on the side of the reinforcing plate away from the GIS pipeline.

[0006] Further, the junction of the second reinforcing rib and the reinforcing plate is arranged in an arc shape.

[0007] Further, the inner wall of the GIS pipeline and the outer wall of the first reinforcing rib array and the outer wall of the GIS pipeline and the outer wall of the second reinforcing rib array are all provided with a corrosion-resistant layer.

[0008] The utility model has the beneficial effects that:

[0009] By welding the first reinforcing rib array in the GIS main pipe and the connecting pipe and welding the second reinforcing rib array on the outer wall of the GIS pipeline, the GIS pipeline can better resist external pressure and impact, thereby improving the safety and stability of the equipment and the overall structural strength of the GIS pipeline.

[0010] The helical reinforcing rib helps to disperse and absorb the impact force from the outside and protect the GIS pipeline from damage.

[0011] Because the reinforcing plates are crisscrossed, they together form a strong resistance system that can effectively prevent GIS pipelines from deforming when subjected to external forces.

[0012] The second reinforcing rib, together with the reinforcing plate, forms a more robust T-shaped support structure, which can effectively disperse and absorb impact forces from the outside, thereby protecting the inside of the GIS pipeline from damage and enhancing the equipment's impact resistance.

[0013] The arc-shaped connection design can effectively reduce stress concentration at the connection between the reinforcing rib and the reinforcing plate, making the stress distribution more uniform and reducing the risk of material fatigue and fracture caused by stress concentration.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1-4 As shown, this utility model discloses a gas-insulated pipeline for GIS equipment, comprising: a GIS pipeline consisting of a GIS main pipe 1 and a connecting pipe 2 welded to the outer wall of the GIS main pipe 1, wherein the inner wall of the connecting pipe 2 is connected to the inner wall of the GIS main pipe 1, and a first reinforcing rib array 3 is welded inside both the GIS main pipe 1 and the connecting pipe 2, and a second reinforcing rib array 4 is welded to the outer wall of the GIS pipeline. By welding the first reinforcing rib array 3 inside the GIS main pipe 1 and the connecting pipe 2, and welding the second reinforcing rib array 4 to the outer wall of the GIS pipeline, the GIS pipeline can better resist external pressure and impact, thereby improving the safety and stability of the equipment, and improving the overall structural strength of the GIS pipeline. The first reinforcing rib array 3 is a spiral-shaped first reinforcing rib, and the spiral shape of the reinforcing rib helps to disperse and absorb the impact force from the outside, protecting the inside of the GIS pipeline from damage. The second reinforcing rib array 4 is composed of crisscrossing reinforcing plates 41. Since the reinforcing plates 41 are crisscrossed, they together form a strong resistance system, which can effectively prevent the GIS pipeline from deforming when subjected to external forces.

[0020] Further, as shown in Figures 3-4 The second reinforcing rib array 4 further comprises a second reinforcing rib 42 integrally arranged on the side of the reinforcing plate 41 away from the GIS pipe, and the second reinforcing rib 42 and the reinforcing plate 41 form a more solid T-shaped support structure together, which can effectively disperse and absorb the impact force from the outside, thereby protecting the inside of the GIS pipe from damage and enhancing the impact resistance of the equipment.

[0021] Further, as shown in Figure 4 The junction of the second reinforcing rib 42 and the reinforcing plate 41 is arranged in an arc shape, and the arc-shaped junction design can effectively reduce the stress concentration phenomenon at the connection between the reinforcing rib and the reinforcing plate, making the stress distribution more uniform and reducing the risk of material fatigue and fracture caused by stress concentration.

[0022] Further, the inner wall of the GIS pipe and the outer wall of the first reinforcing rib array 3, and the outer wall of the GIS pipe and the outer wall of the second reinforcing rib array 4 are all provided with a corrosion-resistant layer (not shown in the figure), the corrosion-resistant layer on the inner wall of the GIS pipe and the outer wall of the first reinforcing rib array 3 is composed of an epoxy asphalt paint layer and a fluorocarbon metal paint layer, and the corrosion-resistant layer on the outer wall of the GIS pipe and the outer wall of the second reinforcing rib array 4 is composed of an epoxy zinc-rich primer layer and a high wear-resistant hydrophobic and oleophobic nano coating layer, the design of the corrosion-resistant layer solves the problem of poor corrosion resistance and easy corrosion damage of existing GIS pipes during use, thereby improving the service life of the GIS pipe.

[0023] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
