Description
Technical Field
[0001] This utility model relates to the technical field of substation grounding devices, and in particular to a grounding component for a wind farm substation. Background Technology
[0002] A wind farm substation is a facility in the power system of a wind power plant that transforms voltage and current, receives electrical energy, and distributes electrical energy. Its function is to step up the electrical energy generated by the generator and feed it into the high-voltage power grid. Grounding components must be installed in wind farm substations to ensure the safe operation of equipment and the safety of workers during operation and maintenance.
[0003] Grounding components in wind farm substations typically involve embedding conductive rods to the ground and conducting electrical energy through lines for grounding. However, most existing grounding components are installed in the soil, resulting in poor installation stability, easy detachment and loosening, affecting the stability of the grounding line. Furthermore, when energized, the top of the component can easily cause current leakage, posing a hazard to operators. Additionally, the inability to rotate the wiring terminals necessitates strict requirements for installation angles, increasing installation difficulty and hindering connection to the pre-buried grounding network. Therefore, this application provides a grounding component for wind farm substations to meet these requirements. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a grounding component for wind farm substations to solve the problems of poor installation firmness of existing grounding components, easy to fall off and loosen, affecting the stability of grounding lines, and easy to cause current overflow when the top is energized, which can cause harm to operators. At the same time, the connection point cannot be rotated, which leads to high requirements for the installation angle during installation, thus increasing the installation difficulty. In addition, it is difficult to connect with the grounding network line pre-buried in the soil.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A grounding assembly for a wind farm substation includes an embedded cylinder with a conductive mechanism inside for grounding conduction; an installation mechanism at the top of the embedded cylinder for equipment installation and positioning; and a wiring mechanism at the top of the conductive mechanism for connecting a grounding line.

[0011] Optionally, an adjustment disc is fixedly connected to the top of the positioning disc, and a protective cover is fixedly connected to the top of the adjustment disc.
[0012] Optionally, the protective cover is semi-circular and is attached to the top of the conductive rod.
[0013] Optionally, the adjustment disc is made of a resin disc with an outer wall comprising insulating ceramic material.
[0014] Optionally, the insertion slot is cross-shaped, and both the conductive rod and the rotating cylinder are made of tungsten copper alloy.
[0015] Optionally, the bottom end of the pre-embedded cylinder is tapered, and a limiting ring is fixedly connected to the top end of the pre-embedded cylinder, the limiting ring being snapped into the inside of the adjusting plate.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above scheme, the grounding device can be pre-buried in the designated location by setting the pre-embedded cylinder, which facilitates the rapid installation of the entire grounding assembly.

[0034] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a grounding component for a wind farm substation, including a pre-embedded cylinder 1, a conductive mechanism 2 is provided inside the pre-embedded cylinder 1 for grounding conduction, an installation mechanism 3 is provided at the top of the pre-embedded cylinder 1 for equipment installation and positioning, and a wiring mechanism 4 is provided at the top of the conductive mechanism 2 for connecting the grounding line.
[0035] The pre-embedded cylinder 1 allows the grounding device to be pre-buried in the designated location, facilitating the rapid installation of the entire grounding assembly. The conductive mechanism 2 enables the rapid transfer of electrical energy to the ground, meeting grounding requirements. The installation mechanism 3 at the top of the pre-embedded cylinder 1 facilitates the limiting and fixing of the entire device, preventing stress that could affect the grounding wire connection and grounding conductivity. The wiring mechanism 4 at the top of the conductive mechanism 2 facilitates interconnection with the grounding wire of the wind farm substation, improving the convenience and robustness of grounding.
[0036] like Figure 1 , Figure 2 and Figure 4 As shown, multiple sets of conductive ring frames 5 are fixedly connected to the outer wall of the pre-embedded cylinder 1. All sets of conductive ring frames 5 are inverted conical in shape. Through the multiple sets of conductive ring frames 5 fixedly connected to the outer wall of the pre-embedded cylinder 1, electrical energy can be quickly transferred to the ground, thereby improving the conductivity. At the same time, the conductive ring frames 5, which are inverted conical in shape, can also continue to hook onto the soil in the opposite direction, improving the installation firmness of the pre-embedded cylinder 1 and preventing it from easily loosening and detaching from the ground.
[0037] like Figure 2 and Figure 3 As shown, the conductive mechanism 2 includes a conductive rod 14 that is installed inside the pre-embedded cylinder 1 with a snap fastener. The bottom end of the conductive rod 14 is provided with a plug-in groove 15. The conductive mechanism 2, including the conductive rod 14 installed inside the pre-embedded cylinder 1 with a snap fastener, facilitates the conduction of electrical energy. At the same time, the plug-in groove 15 at the bottom end of the conductive rod 14 can be used to plug into the grounding network under the wind farm substation to complete the grounding connection, expand the conductivity range, and improve the grounding effect.
[0038] like Figure 1 and Figure 3 As shown, the wiring mechanism 4 includes a rotating cylinder 11 rotatably mounted on the top of the conductive rod 14. A connecting rod 12 is fixedly connected to the outer wall of the rotating cylinder 11. A wiring ring 13 is fixedly connected to one end of the connecting rod 12. The rotating cylinder 11 at the top of the conductive rod 14 allows for easy rotation of the wiring ring 13, accommodating the connection of wires in different directions and avoiding the situation where the wire cannot be connected to the preset grounding wire due to installation angle issues.
[0039] like Figure 1 and Figure 4 As shown, the installation mechanism 3 includes a positioning plate 6 fixedly installed at the top of the pre-embedded cylinder 1. A limiting pin 9 is fixedly connected to the bottom of the positioning plate 6. The limiting pin 9 is triangular in shape. By fixing the positioning plate 6 at the top of the pre-embedded cylinder 1, it is convenient to cooperate with the limiting pin 9 fixedly connected to the bottom of the positioning plate 6 to firmly fix the entire device to the ground.
[0040] like Figure 1 and Figure 4 As shown, an adjustment plate 7 is fixedly connected to the top of the positioning plate 6, and a protective cover 10 is fixedly connected to the top of the adjustment plate 7. The adjustment plate 7 fixedly connected to the top of the positioning plate 6 facilitates the rotation of the positioning plate 6 with the rotating cylinder 11, changing the orientation of the protective cover 10, thereby meeting the needs of the protective cover 10 to protect the top of the conductive rod 14 and the rotating cylinder 11, and improving the protective effect of the grounding device.
[0041] like Figure 4As shown, the protective cover 10 is semi-circular and covers the top of the conductive rod 14. The semi-circular protective cover 10 provides protection to the top of the conductive rod 14 and the rotating cylinder 11, while also preventing the release of electrical energy caused by the arc generated at the metal contact point, which could lead to a dangerous situation.
[0042] like Figure 4 As shown, the regulating disc 7 is made of a resin disc with an outer wall containing insulating ceramic material, which can serve as an insulation function to prevent electrical energy from being released directly on the ground and causing safety hazards.
[0043] like Figure 3 As shown, the insertion slot 15 is cross-shaped, and both the conductive rod 14 and the rotating cylinder 11 are made of tungsten copper alloy. The cross-shaped insertion slot 15 facilitates the insertion of the conductive rod 14 into the pre-embedded grounding network, enhancing the grounding conductivity. Moreover, the conductive rod 14 and the rotating cylinder 11, both made of tungsten copper alloy, have high strength and are not easily damaged, and have excellent conductivity and discharge effect.
[0044] like Figure 1 and Figure 4 As shown, the bottom end of the pre-embedded cylinder 1 is conical, and the top end of the pre-embedded cylinder 1 is fixedly connected to a limiting ring 8. The limiting ring 8 is snapped into the inside of the adjusting plate 7. The pre-embedded cylinder 1 with a conical bottom end is easy to insert into the ground soil, which facilitates the installation of the pre-embedded cylinder 1. At the same time, the limiting ring 8 fixedly connected to the top end of the pre-embedded cylinder 1 can improve the connection strength between the pre-embedded cylinder 1 and the adjusting plate 7.
[0045] The working principle of the technical solution provided by this utility model is as follows: The pre-embedded cylinder 1 is pre-embedded at the designated location of the grounding device and is located directly above the grounding network line. The positioning plate 6 is used to limit and fix the pre-embedded cylinder 1. Then, the conductive rod 14 is inserted into the pre-embedded cylinder 1 so that the insertion groove 15 at the bottom of the pre-embedded cylinder 1 is engaged with the grounding network line. Then, the adjusting plate 7 is connected to the positioning plate 6. The rotating cylinder 11 is connected to the top of the conductive rod 14. Finally, the protective cover 10 is fixed to the top of the adjusting plate 7, and the installation of the entire grounding assembly is completed. Then, the grounding wire of the wind farm substation is connected and fixed to the connecting ring 13, and the grounding connection operation is completed.
[0046] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
