Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to the field of mechanical component technology, specifically referring to a color-changing modular GIS shell. Background Technology

[0002] GIS is short for Gas Insulated Enclosed Switchgear. With the continuous development of technology, GIS equipment has been widely used in various fields. GIS enclosures are not only widely used in high voltage and ultra-high voltage fields, but also in extra-high voltage fields. GIS enclosures have the characteristics of compact structure, small footprint, high reliability, flexible configuration, convenient installation, strong safety, and strong environmental adaptability. They are a commonly used enclosed protective structure.

[0003] In current GIS housing design, most are composed of an integrated structure. During use, if the housing malfunctions or other issues require maintenance or repair, the integrated design makes it difficult to disassemble, causing inconvenience for subsequent maintenance and repair. At the same time, when internal components discharge with the metal outer shell, the external metal shell prevents personnel from seeing the discharge point and repairing it, leading to the continuous amplification of the fault and, in severe cases, power outages. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a color-changing modular GIS housing, which is easy to disassemble and allows for quick location of discharge points via a discharge display layer, facilitating rapid repair.

[0005] This utility model is achieved through the following technical solution: a color-changing combined GIS shell, comprising two oppositely arranged semi-shells with a semi-circular cross-section, and an end face locking structure located at both ends of the semi-shells and locking the two semi-shells, a sealing structure provided on the connecting surface of the two semi-shells, and a discharge display layer provided on the outer surface of the two semi-shells.

[0006] In use, this preferred solution uses a split structure instead of a one-piece structure by setting up two half-shells, which facilitates loading and unloading. At the same time, the sealing and locking structures ensure the sealing and connection strength of the shell. In addition, the discharge display layer can quickly locate the discharge point, which facilitates rapid maintenance.

[0007] Preferably, the locking structure includes a flange and a fastening ring connected to the overflow end face. The half-shell end face is provided with a semi-fixed ring that is adapted to the shape of the half-shell end face and has an outer diameter smaller than that of the half-shell. The two semi-fixed rings are joined together to form a fully fixed ring inserted into the fastening ring.

[0008] This preferred solution, through the use of flanges, fastening rings, and semi-fixed rings, facilitates the fixing of the shell at both ends of the semi-shell.

[0009] Preferably, the semi-fixed ring and the fastening ring are threaded together, and the second sealing structure has an annular groove on the end face of the fastening ring away from the flange that connects to the inner ring of the fastening ring, and a sealing ring that is pressed against the end face of the semi-shell is provided in the annular groove.

[0010] This preferred solution enhances the connection strength between the semi-fixed ring and the fastening ring through the threaded connection, while the ring groove and sealing ring achieve a sealed connection between the flange and the semi-shell.

[0011] Preferably, an annular block is also provided between the sealing ring and the semi-shell. This preferred embodiment, by providing the annular block, appropriately adjusts the distance between the semi-shell and the sealing ring, ensuring the compressive strength of the sealing ring.

[0012] Preferably, the semi-shell is threaded with bolts, which are threaded onto a fastening ring.

[0013] This preferred solution enhances the connection strength between the semi-shell and the fastening ring by using bolts.

[0014] Preferably, the sealing structure includes a plurality of protrusions arranged on the mating surface of one half-shell and along the axial direction of the half-shell, and a groove on the mating surface of the other half-shell that mates with the protrusions. Conical sealing blocks are fixed to the two side walls of the protrusions. The large-diameter end of the sealing block is connected to the mating surface of one half-shell. The groove is also conical, with the opening width of the groove being greater than the bottom width of the groove. The maximum width of the two sealing blocks is greater than the opening width of the groove.

[0015] This preferred solution achieves a sealing effect on the mating surfaces of the two semi-shells through the cooperation of protrusions, sealing blocks, and grooves.

[0016] The beneficial effects of this utility model are as follows: by setting two half-shells, a split structure replaces the integrated structure, which facilitates loading and unloading. At the same time, the sealing structure and locking structure ensure the sealing and connection strength of the shell. The discharge display layer enables quick location of the discharge point, facilitating rapid maintenance. The flange, fastening ring, and semi-fixed ring facilitate fixing the shell at both ends of the half-shells. The threaded connection enhances the connection strength between the semi-fixed ring and the fastening ring. The ring groove and sealing ring achieve a sealed connection between the flange and the half-shell. Attached Figure Description

[0024] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0025] See attached document Figure 1-5 The present invention provides a color-changing combined GIS shell, comprising two oppositely arranged semi-circular shells 1, and an end face locking structure located at both ends of the semi-shells 1 and locking the two semi-shells 1 together to form a full shell.

[0026] The mating surfaces of the two half-shells 1 are two planes that extend along the axial direction of the full shell and are arranged radially along the full shell. A sealing structure is provided on the connecting surfaces of the two half-shells 1. The sealing structure includes a plurality of protrusions 8 located on the mating surface of one half-shell 1 and arranged along the axial direction of the half-shell 1, and a groove 10 located on the mating surface of the other half-shell 1 and cooperating with the protrusions 8. Conical sealing blocks 9 are fixed to the two side walls of the protrusions 8. The large-diameter end of the sealing block 9 is connected to the mating surface of one half-shell 1. The groove 10 is also conical. The opening width of the groove 10 is greater than the bottom width of the groove. The maximum width of the two sealing blocks 9 is greater than the opening width of the groove 10.

[0027] The outer surfaces of the two semi-shells 1 are provided with a discharge display layer. The discharge display layer can be a sprayed layer or a discharge display sticker for adhesion. The discharge display layer is a prior art technology that can change color under the action of a high voltage electric field, such as an electrochromic material. Depending on the properties of this material, it can be made into a coating or a patch for use.

[0028] The locking structure includes a flange 2 and a fastening ring 3 connected to the overflow end face. The end face of the semi-shell 1 is provided with a semi-fixed ring 4 that is adapted to the shape of the end face of the semi-shell 1 and has an outer diameter smaller than that of the semi-shell 1. The two semi-fixed rings 4 are joined together to form a fully fixed ring inserted into the fastening ring 3.

[0029] The semi-fixed ring 4 and the fastening ring 3 are threaded together. The second sealing structure has an annular groove on the end face of the fastening ring 3 away from the flange 2, which is connected to the inner ring of the fastening ring 3. A sealing ring 5 is provided in the annular groove and is pressed against the end face of the semi-outer shell 1.

[0030] A ring block 6 is also provided between the sealing ring 5 and the semi-outer shell 1. A bolt 7 is threadedly connected to the semi-outer shell 1, and the bolt 7 is threadedly connected to the fastening ring 3.

[0031] When using this invention, after aligning the mating surfaces of the two half-shells 1, the protrusion 8 and the sealing block 9 are inserted into the groove 10. The sealing block 9 is compressed to enhance the connection strength and form a seal. Then, the fastening ring 3 is threaded onto the full fixing ring, and the sealing ring 5 is pressed onto the ring block 6. When a discharge occurs inside the shell, the discharge display layer changes color at the discharge point, thereby determining the discharge location.
