Description

Technical Field

[0001] The invention belongs to the technical field of grounding, in particular to a vertical grounding device suitable for high soil areas. Background Art

[0002] At present, grounding refers to the connection of the neutral point of the power system and electrical equipment, the exposed conductive parts of the electrical equipment and the conductive parts outside the equipment to the earth through conductors. It can be divided into working grounding, lightning protection grounding and protective grounding; working grounding is set up by the operation needs of the power system (such as neutral point grounding), so under normal circumstances, there will be a long-term current flowing through the grounding electrode, but it is only an unbalanced current of several amperes to tens of amperes. When a ground fault occurs in the system, thousands of amperes of working current will flow through the grounding electrode, but this current will be cut off by the relay protection device within 0.05-0.1s, and even if it is a backup protection, the action is generally within 1s; lightning protection grounding is grounding designed to eliminate the impact of overvoltage hazards, such as the grounding of lightning rods, lightning conductors and lightning arresters. Lightning protection grounding only allows current to flow under the action of lightning strikes. The amplitude of lightning current flowing through the lightning protection grounding electrode can reach tens to hundreds of kiloamperes, but the duration is very short; protective grounding is set to prevent equipment from being charged due to insulation damage and endangering personal safety, such as the metal casing of power equipment, reinforced concrete poles and metal pole towers. Protective grounding only allows current to flow when the insulation of the equipment is damaged, and its value can vary within a large range.

[0003] Distribution grounding devices are classified into various types according to equipment capacity, purpose and environment. The various types of grounding devices in the current typical design and testing specifications of the distribution network of State Grid Corporation and Southern Grid Corporation are composed of multiple parts. The design, bidding and installation are time-consuming and require on-site welding, manufacturing and installation, and the quality cannot be guaranteed. In the low-voltage distribution complete set, in order to meet the requirements of electrical grounding continuity, there is usually a grounding point on the door panel of the low-voltage cabinet or box. The grounding method of the grounding point is usually to spray-weld a section of screw on the inner side of the door panel;

[0004] When designing the grounding resistance value of the grounding grid, it is necessary to conduct theoretical analysis and calculation on the actual situation of the project, and then take a feasible plan for construction, so as to avoid economic losses caused by unnecessary engineering errors; With the development of informatization, the grounding resistance value requirements are getting lower and lower. In the transformation of conventional lightning protection grounding grids, the resistance reduction measures currently used mainly include extended grounding, increasing the grounding grid area, using resistance reduction agents, and increasing the number of vertical grounding electrodes.

[0005] However, due to limited urban land resources and high land prices, it is not advisable to achieve resistance reduction by increasing the grounding grid area; in the case of low resistance, even if a resistance reducing agent is used, the resistance reduction effect is not obvious, and the cost is very high; the grounding down conductor of the transmission line tower grounding device, in the prior art, the grounding down conductor device is made of round steel, which will be corroded after a period of use. After being corroded, its own resistance increases, and its conductivity decreases, which is prone to lightning accidents, causing the transmission line to trip; on the other hand, after a long period of research, the area where the round steel down conductor is severely corroded is concentrated at the contact interface between the soil and the air. The flexible graphite grounding down conductor has good corrosion resistance and is the best substitute for the round steel down conductor, but the connection between the flexible graphite grounding down conductor and the underground round steel grounding grid is difficult to achieve, and it cannot be achieved by welding;

[0006] Even if you use connection tools to connect the flexible graphite grounding lead and the underground round steel grounding grid, such as using screws, steel hoops, etc., or indenting according to the shape of the wire, you need to use tools to operate. If the tools are damaged, unsuitable, or not brought with you, the connection work cannot be completed. Summary of the invention

[0047] The aforementioned adjustment mechanism comprises an assembly part and a steel wire which are screw-assembled on the surface of a stainless steel sleeve;

[0048] Wherein, the surface of the insertion rod and the positions adjacent to each node ring are provided with assembly holes for the insertion of the assembly parts; the two ends of the steel wire are respectively welded to two groups of welding rods, and the middle part is wound around the surface of the assembly parts.

[0049] 2- Connect components

[0050] The connecting assembly comprises two sets of baffles and a twisting rod symmetrically assembled on the surface of the convex head;

[0051] Among them, when the convex head is inserted into the tooth groove, the edge of the baffle is stuck in the preset tooth mouth in the tooth groove, and the baffle and the convex head are connected by a rotating shaft with a torsion spring; one end of the twisting rod is inserted into the surface of the copper-plated connecting rod, and is connected to the copper-plated connecting rod by a bearing, and the end of the twisting rod inserted into the copper-plated connecting rod is connected to the two groups of baffles by a rope transmission.

[0052] The above-mentioned No. 1 copper-plated connecting rod and the stainless steel sleeve are connected through a connecting component, and a heat shrink tube is sleeved on the connecting end surface of the No. 1 copper-plated connecting rod and the stainless steel sleeve.

[0053] One end of the galvanized steel connecting sleeve is connected to the No. 2 copper-plated connecting rod, and the other end is fixedly connected to the cable; the specifications of the galvanized steel connecting sleeve and the plug rod are consistent.

[0054] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0055] Embodiment 1:

[0056] This embodiment provides the specific structure of the entire device, such as Figure 1-7 As shown, a vertical grounding device suitable for high soil areas comprises a galvanized steel connecting plate 1, a copper-plated connecting rod group and a galvanized steel connecting sleeve 6 connected in sequence;

[0057] The galvanized steel connecting plate 1 is fixedly connected to the grounding rod joint inserted into the soil, and the end of the galvanized steel connecting plate 1 is integrally connected with the plug rod 7;

[0058] Specifically, the galvanized steel connecting plate 1 is in the shape of a flat plate. Figure 1 It can be seen that a fixing bolt hole is opened on one end of the galvanized steel connecting plate 1, and the connecting head and the flexible graphite are connected by crimping and riveting.

[0059] The copper-plated connecting rod group includes at least two copper-plated connecting rods, namely, a No. 1 copper-plated connecting rod 4 and a No. 2 copper-plated connecting rod 5, and a connecting assembly is installed on the copper-plated connecting rod group for connecting components adjacent to the copper-plated connecting rod group. A stainless steel sleeve 2 is welded to one end of the No. 1 copper-plated connecting rod 4, and the stainless steel sleeve 2 is sleeved on the outside of the plug rod 7. The use of the above-mentioned stainless steel sleeve 2 can play a role in physical isolation of the plug rod 7 as the body of the grounding down conductor;

[0060] One end of the galvanized steel connecting sleeve 6 is connected to the No. 2 copper-plated connecting rod 5, and the other end is fixedly connected to the cable.

[0061] In some examples, the outer surface of the plug rod 7 is provided with a plurality of equally spaced node rings 71, and the stainless steel sleeve 2 is sleeved on the surface of the plug rod 7. The node ring 71 is a convex structure, which can limit the stainless steel sleeve 2 after the stainless steel sleeve 2 and the plug rod 7 are sleeved together.

[0062] In addition, if Figure 1 It can be seen that the designer can also set a connection structure between the stainless steel sleeve 2 and the plug rod 7 at one end of the galvanized steel connecting sleeve 6. At this time, the plug rod 7 is used as an electrical connector. The length of the entire grounding device is adjustable, and the stainless steel sleeve 2 can be installed at different positions on the plug rod 7.

[0063] When the stainless steel sleeve 2 is connected to the plug rod 7,

[0064] Users only need to hold Figure 4 The assembly part 18 is then twisted so that the steel wire 17 is wound around the surface of the assembly part 18. The two sets of welding rods 16 are close to each other, so that the stainless steel sleeve 2 is deformed and the corresponding position of the pipe is reduced, and finally a Figure 3 The state of the recessed portion 8 shown;

[0065] The production of the traditional recessed portion 8 requires a pressing process with the aid of a special tool.

[0066] A positioning assembly is disposed on the outer surface of the stainless steel sleeve 2 for forming a plurality of recessed portions 8 on the surface of the stainless steel sleeve 2 to position adjacently distributed node ring portions 71 .

[0067] The positioning assembly comprises two sets of parallelly distributed welding rods 16 and an adjustment mechanism;

[0068] The welding rod 16 is welded to the outer surface of the stainless steel sleeve 2 and is located in the area formed between two adjacent sets of node ring portions 71;

[0069] The adjustment mechanism is used to adjust the spacing between the two groups of welding rods 16; the adjustment mechanism includes an assembly part 18 and a steel wire 17 which are spirally assembled on the surface of the stainless steel sleeve 2; wherein, assembly holes 9 are provided at positions adjacent to each node ring portion 71 on the surface of the insertion rod 7 for the assembly part 18 to be inserted; the two ends of the steel wire 17 are respectively welded to the two groups of welding rods 16, and the middle part is wound around the surface of the assembly part 18.

[0070] By adopting the above technical solution:

[0071] Compared with the traditional method of crimping the flexible graphite down conductor and the round steel using special tools, in this solution, the stainless steel sleeve 2 and the plug rod 7 can be inserted into each other, and then the crimping process can be achieved by manually tightening with the help of a positioning component, avoiding the use of tools and also eliminating the need for welding between metals. The installation is quick and convenient, and the stability of the stainless steel sleeve 2 and the plug rod 7 after connection can be ensured.

[0072] Embodiment 2:

[0073] Based on Example 1, this example provides a specific structure of the connecting assembly and the copper gasket, such as Figure 5 and 6 As shown, the copper-plated connecting rod group includes at least two copper-plated connecting rods, namely, a No. 1 copper-plated connecting rod 4 and a No. 2 copper-plated connecting rod 5, and a connecting assembly is installed on the copper-plated connecting rod group for connecting components adjacent to the copper-plated connecting rod group, and a stainless steel sleeve 2 is welded to one end of the No. 1 copper-plated connecting rod 4, and the stainless steel sleeve 2 is sleeved on the outside of the plug rod 7;

[0074] The shape and specification of the No. 1 copper-plated connecting rod 4 and the No. 2 copper-plated connecting rod 5 are consistent. One end of the No. 1 copper-plated connecting rod 4 is set as a convex head 11, and the other end is provided with a tooth groove 10 for the convex head 11 to be inserted. The surface of the convex head 11 is covered with a copper gasket 15.

[0075] In this solution, the number of copper-plated connecting rods used can be increased or decreased according to the local soil resistivity and the specific implementation plan to achieve a better resistance reduction effect.

[0076] In some examples, the cross section of the copper gasket 15 is bowl-shaped, and a through hole 151 is opened in the middle of the copper gasket 15 for the male head 11 to pass through; the connecting assembly includes two sets of baffles 12 and a screw rod 14 symmetrically assembled on the surface of the male head 11;

[0077] When using the connection component,

[0078] If the staff needs to install an additional set of copper-plated connecting rods, the No. 1 copper-plated connecting rod 4 and the No. 2 copper-plated connecting rod 5 can be separated. It is only necessary to manually rotate the twist rod 14 on the No. 2 copper-plated connecting rod 5 so that the rope body 13 drives the two sets of baffles 12 to move toward the inside of the convex head 11, and then the No. 1 copper-plated connecting rod 4 and the No. 2 copper-plated connecting rod 5 can be manually separated. After separation, the two sets of baffles 12 in the No. 2 copper-plated connecting rod 5 will be restored to the state as shown below under the elastic restoring force of the torsion spring. Figure 6 The initial state shown in the figure can be achieved by adding a set of copper-plated connecting rods according to the same principle.

[0079] When the convex part 11 is inserted into the tooth groove 10, the edge of the baffle 12 is inserted into the preset tooth opening in the tooth groove 10, and the baffle 12 and the convex part 11 are connected by a rotating shaft with a torsion spring, and the entire rotating shaft drives the baffle 12 to deflect under the elastic restoring force of the torsion spring;

[0080] One end of the twist rod 14 is inserted into the surface of the copper-plated connecting rod and is connected to the copper-plated connecting rod by setting a bearing. One end of the twist rod 14 inserted into the copper-plated connecting rod is connected to the two sets of baffles 12 through a rope body 13. The No. 1 copper-plated connecting rod 4 and the stainless steel sleeve 2 are connected by a connecting assembly, and a heat shrink tube 3 is set on the connecting end surface of the No. 1 copper-plated connecting rod 4 and the stainless steel sleeve 2. The use of the heat shrink tube 3 here can greatly improve the corrosion resistance of the entire grounding down conductor device, inhibit its electrochemical reaction in the soil and air, and also improve the conductive dispersion capacity of the grounding system, thereby improving the service life of the grounding down conductor and ensuring the stable and good operation of the entire power system.

[0081] By adopting the above technical solution:

[0082] The connecting assembly is used as a connecting unit for the copper-plated connecting rod and its adjacent parts. In the connected state, the bowl-shaped copper gasket 15 has good conductivity and is always clamped in the middle position, which can increase the friction and make the connection between the two parts more secure. When the connecting assembly is used, it can be disassembled and assembled by rotating. While the connection is stable, the adjacent parts can also be rotated. This is different from the traditional connection structure, which can only twist its own position if it needs to be rotated and adjusted after connection.

[0083] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
