Problems solved by technology

[0003] At present, the existing grounding rods suitable for grounding conductive busbars in switch cabinets mainly have two structural forms: T-shaped and U-shaped. Because the terminal is fixedly connected to the insulating rod, the angle of the end cannot be adjusted, and it is inconvenient to use and operate. , and after the grounding wire is suspended in the cabinet, the insulating rod takes up a large space, which affects the construction

Abstract

The invention discloses an angle-adjustable combined ground rod, which is characterized by comprising a lower insulation rod (1), wherein the lower insulation rod (1) is connected with a transmission rod (3) arranged in an upper insulation rod (2), clamp sleeves (6) are arranged at the upper end of the upper insulation rod (2) and connected with an irregular connection part (8) in assembling mode, inner threads of the irregular connection part (8) are connected with an ejector rod (1), and the ejector rod (1) is connected with the transmission rod (3) in assembling mode. The upper portion of the irregular connection part (8) is connected with a grounding terminal upper end head (18) through a first pin column (13), a grounding screw (19) is arranged on the grounding terminal upper end head (18), a fastening bolt (12) is arranged on the upper portion of the irregular connection part (8), the grounding terminal upper end head (18) is connected with a triangular connection body (16) through a second pin column (14), and the triangular connection body (16) is connected with a grounding terminal lower end head (20) through a third pin column (15). The angle-adjustable combined ground rod is simple and practical in structure, flexible to use, convenient to operate and small in occupied space.

Description

[0001] Technical field: [0002] The invention relates to a combined ground rod with adjustable angle, which belongs to the technical field of electric power system substation operation. Background technique: [0003] At present, the existing grounding rods suitable for grounding conductive busbars in switch cabinets mainly have two structural forms: T-shaped and U-shaped. Because the terminal is fixedly connected to the insulating rod, the angle of the end cannot be adjusted, and it is inconvenient to use and operate. , and after the grounding wire is suspended in the cabinet, the insulating rod takes up a large space, which affects the construction. Invention content: [0004] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a combined grounding rod with simple and practical structure, flexible use, convenient operation, and small space occupation with adjustable angle. [0005] The purpose of the present i...
