Description

Technical Field

[0001] This utility model relates to the field of power engineering equipment, and mainly to a protective box for connecting the grounding copper busbar and the grounding grid of an indoor GIS equipment. Background Technology

[0002] When GIS equipment is installed indoors, grounding is a crucial aspect to ensure the safe operation of the equipment and the personal safety of personnel. Conventional grounding methods, where the grounding copper busbar and grounding grid are exposed, lack adequate protection measures. During construction or operation, these connections are easily damaged by external forces, affecting the reliability and safety of the grounding system. Therefore, this invention proposes a protective box for the connection between the indoor grounding copper busbar and the grounding grid for GIS equipment. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a protective box for connecting the indoor grounding copper busbar and the grounding grid of GIS equipment. This device effectively eliminates the impact of external forces on the grounding connection by placing the connection point of the GIS equipment's grounding copper busbar and the grounding grid in a stainless steel protective box buried in the indoor floor or equipment foundation, thus preventing damage to the grounding connection and ensuring the reliability and safety of the grounding system, providing conditions for the stable operation of GIS equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A protective box for connecting the grounding copper busbar and the grounding grid of an indoor GIS equipment includes a box body 1, which is embedded in a concrete floor 3. A slot 4 is provided at the bottom of the box body 1, and a grounding wire 5 is connected to the bottom of the slot 4. The upper end of the grounding wire 5 is placed inside the box body 1 and connected to a grounding copper busbar 6.

[0006] The box body 1 is movably connected to the box cover 2, and the surface of the box cover 2 is provided with a through groove. The upper end of the grounding copper busbar 6 passes through the through groove on the box cover 2.

[0007] Furthermore, the box body 1 and the box cover 2 are connected by a slot-type connection.

[0008] Furthermore, the box body 1 is a cuboid, and the material of the box body 1 is stainless steel plate with a thickness of 2mm.

[0009] Furthermore, the size of the slot 4 is 5mm larger on each side than the size of the grounding wire.

[0010] Furthermore, the box is made of stainless steel plate with a thickness of 4mm.

[0011] Furthermore, the through slot on the cover 2 is 5mm larger on each side than the grounding copper busbar.

[0012] Compared with the prior art, the protective box of this utility model has the following beneficial effects:

[0013] This invention effectively eliminates the impact of external forces on the grounding connection points by placing the grounding copper busbar and grounding grid connection points of the GIS equipment in a stainless steel protective box buried in the indoor floor, thus preventing damage to the grounding connection points. This ensures the reliability and safety of the grounding system and provides conditions for the stable operation of the GIS equipment. Attached Figure Description
