Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a grounding device for an electric power system. Background Art

[0002] In the power system, for the needs of work and safety, it is often necessary to connect some parts of the power system and its electrical equipment to the earth. This is grounding. The "ground" in the power system refers to the earth's conductive material, the potential of any point of which is conventionally taken as 0. Grounding refers to the conductive connection between the circuit or equipment and the earth or some conductor that replaces the earth, that is, the metallic connection;

[0003] A grounding device is used in grounding operations. It refers to the general term for the grounding electrode buried underground and the connecting wire from the grounding electrode to the equipment. The grounding device is composed of a grounding body buried in the soil (round steel, angle steel, flat steel, steel pipe, etc.) and a grounding wire for connection.

[0004] One of the most common power system equipment is the power pole tower. The general power pole tower grounding device usually directly connects the grounding wire to the grounding rod, and then inserts the grounding rod into the ground. The stability of this grounding structure is relatively limited, and the power pole tower itself needs to be buried deep in the ground, which makes the construction complicated. At the same time, some grounding structures may be exposed due to the construction method, which is prone to structural damage.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a power system grounding device is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a grounding device for an electric power system to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric power system grounding device, comprising a base assembly and a stabilizing hoop, a grounding rod is vertically inserted in the center of the base assembly, and support frames are vertically installed around the top of the base assembly, the stabilizing hoop is fixedly connected to the upper end of the support frame, and the four corners of the base assembly are vertically slidably inserted with plungers, one side of the stabilizing hoop is threadedly connected with a fastening bolt, and the connection between the support frame and the base assembly is threadedly connected with a fixing bolt, the stabilizing hoop comprises a limiting ring frame, an anti-slip pad, a docking block and a connecting ear, the inner arc surface of the limiting ring frame is covered with an anti-slip pad, and the side of the limiting ring frame away from the anti-slip pad is connected to the docking block, and connecting ears are provided on both sides of the limiting ring frame.

[0008] Furthermore, the base assembly includes a grounding seat, a reinforcement frame and an insert pipe. The reinforcement frame is installed in the middle of the grounding seat, and the insert pipe is arranged in the center of the reinforcement frame.

[0009] Furthermore, the grounding seat is arranged in a "mouth"-shaped structure and is welded to the reinforcing frame, and the reinforcing frame provides structural support and stability for the grounding seat.

[0010] Furthermore, the base assembly also includes auxiliary piles, slots and fixing screw holes. Auxiliary piles are arranged at the four diagonals of the grounding seat, a slot is opened on the top surface of the grounding seat, and fixing screw holes are opened on the four side facades of the grounding seat.

[0011] Furthermore, the slot and the fixing screw hole are both distributed on the top surface and the side surface of the grounding seat in a "cross" structure, and the fixing screw hole horizontally penetrates and communicates with the interior of the slot.

[0012] Furthermore, the support frame includes a column, a tenon and a connecting screw hole. The bottom of the column is provided with a tenon, and the middle of the tenon is provided with a connecting screw hole.

[0013] Furthermore, the surface structure of the tenon matches the inner surface structure of the slot, and the internal structure of the connecting screw hole is the same as the internal structure of the fixing screw hole.

[0014] Furthermore, the internal structure of the connecting screw hole and the fixing screw hole match the outer surface structure of the fixing bolt, and the fastening bolt and the connecting ear are threadedly connected.

[0015] The utility model provides a grounding device for an electric power system, which has the following beneficial effects:

[0016] 1. In the utility model, when using the stabilizing hoop and the supporting frame, it is only necessary to fix the limiting ring frame of a quarter circle to one side of the supporting frame by welding with the docking block on one side, and use four sets of supporting frames and stabilizing hoops to surround the surrounding surface of the power pole tower, and the four sets of limiting ring frames are docked with each other to form a circular ring structure, and the connecting ears at the docking positions are aligned with the positions, and the fastening bolts are screwed into them, so that the grounding rod and the stabilizing hoop can be fixed to the surrounding of the power pole tower, and then the supporting frame and the base assembly can be connected and fixed by the structural insertion method and the use of fixing bolts, so as to provide a solid foundation for the entire power pole tower. The lower end of the power pole tower provides an effective base structure, and four sets of plugs are vertically inserted into the auxiliary piles. Through the use of the above structure, it is ensured that when the lower end of the power pole tower is buried low, the stability of the structure can be maintained as much as possible. At the same time, the above structure can also protect the lower end of the power pole tower to a certain extent from the direct influence of external forces. Furthermore, by using the above structure, the grounding rod inserted in the center of the base assembly will be in the center of the power pole tower. The power pole tower itself is used to protect the grounding rod from damage caused by external factors, thereby avoiding the occurrence of grounding faults as much as possible.

[0017] 2. The utility model has slots and fixing screw holes opened on the top surface and side surfaces of the grounding base, and cooperates with the tenons and connecting screw holes set at the bottom of the column, so that the base assembly and the support frame have structural assembly properties. At the same time, when the entire device is not in use, the stabilizing hoop and the support frame itself also adopt a split structure. By using the above structure, the entire device can effectively ensure the convenience of mobile transportation, can minimize the space occupied by the structure during movement, and is convenient for packaging and transportation, thereby ensuring the overall structural flexibility of the device. In subsequent combined use, the structural joints can be welded by external welding equipment, thereby ensuring the strength and overall stability of the entire device after the structural connection, thereby protecting the power pole tower and providing it with a foundation.

[0026] like Figures 1 to 5As shown, the base assembly 1 includes a grounding base 101, a reinforcement frame 102 and an insertion tube 103.
