Description

Technical Field

[0001] The utility model relates to the technical field of electric power grounding, in particular to a resistance reducing device for grounding resistance of a lightning arrester. Background Art

[0002] To ensure the safe and reliable operation of the power grid and electrical equipment, both power and electrical equipment must be reliably grounded, and the reliability of the grounding must be manually checked regularly. The level of grounding resistance is directly related to the geological conditions of the grounding point and the moisture level in the soil. In some areas with high soil resistivity or rocky terrain, resistance reducers and ion release agents are used to reduce the grounding resistance during the grounding construction process to ensure the reliability of the grounding. However, in the rainy season, the resistance reducers and ion release agents will be washed away by rainwater, and in the dry season, as the moisture in the soil evaporates, the grounding resistance will directly increase. If the grounding resistance increases during the detection period and is not dealt with in a timely manner, it will pose a major safety hazard to the operation of the power grid and electrical equipment.

[0003] A grounding resistance reduction device for a distribution transformer disclosed in announcement number CN205319344U includes a longitudinal tube and a transverse tube. The longitudinal tube includes side longitudinal tubes located on both sides and an intermediate longitudinal tube located in the middle. The upper and lower ends of the side longitudinal tubes are respectively connected with transverse tubes. The side longitudinal tubes and the transverse tubes form a closed circulation pipeline. The middle of the transverse tubes is connected with an intermediate longitudinal tube. The intermediate longitudinal tube is connected with an irrigation pipe that is conductive to the ground. The resistance reducing agent enters the longitudinal tube and the transverse tube through the irrigation pipe. Due to the implementation of the above technical solution, the present invention enters the soil along with the transformer grounding electrode. By injecting a liquid containing the resistance reducing agent, the resistance reducing agent can directly penetrate into the soil near the grounding electrode, which can effectively reduce the grounding resistance and is simple to operate.

[0004] Although the above patent achieves the goal of injecting a liquid containing a resistance reducing agent so that the resistance reducing agent can directly penetrate into the soil near the grounding electrode, which can effectively reduce the grounding resistance and is simple to operate; however, it lacks a reasonable grounding conductive structure, resulting in components such as transformers and lightning arresters being unable to conduct electricity to the ground well.

It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0026] In one embodiment, Figures 1 to 2 As shown, a lightning arrester grounding resistance reduction device is provided, comprising: a grounding mechanism 5, an underground support frame, a resistance reduction mechanism 4 and a water storage mechanism 14;

[0027] The support frame is used to be arranged under the ground 1, the resistance reduction mechanism 4 is arranged on the support frame, the grounding mechanism 5 is connected to the support frame, and the grounding mechanism 5 at least partially protrudes above the ground 1;

[0028] The water storage mechanism 14 includes a liquid storage container 1402 and a water diversion pipe 6. The water diversion pipe 6 is used to be set on the ground 1. A pipe mouth is set at one end of the water diversion pipe 6, and the other end of the water diversion pipe 6 is connected to the liquid storage container. The liquid storage container is provided with an inlet 1403. The inlet 1403 is provided with a detachable sealing cover 1404. The sealing cover 1404 is used to seal the inlet 1403. An outlet valve 1405 is set at the bottom of the liquid storage container.

[0029] In this embodiment, the grounding mechanism 5 is used to connect the lightning arrester, and the grounding mechanism 5 protrudes from the ground 1 to facilitate the connection of the grounding lead of the lightning arrester. The resistance reduction mechanism 4 is used to reduce the grounding resistance, and the resistance reduction mechanism 4 is structurally stable through the support of the support frame. In this embodiment, the number of resistance reduction mechanisms 4 is multiple, and the support of the support frame makes the arrangement of the resistance reduction mechanism 4 more orderly. In this embodiment, the support frame is a metal support frame with conductive properties, so that the support frame can not only support the resistance reduction mechanism 4, but also realize electrical conduction of the resistance reduction mechanism 4. In this way, the electricity of the lightning arrester can be conducted to the support frame and the resistance reduction mechanism 4 connected to the support frame through the grounding mechanism 5.

[0030] The nozzle of the water diversion pipe 6 is used to let in rainwater, collect rainwater, and collect the collected rainwater into the liquid storage container. In addition, the liquid storage container is also used to load the resistance reducing agent, which penetrates into the surrounding soil through the outlet valve 1405 to achieve the purpose of reducing resistance. In this embodiment, the sealing cover 1404 is threadedly connected to the side wall of the filling port 1403. In this way, the filling port 1403 can be opened by turning the knob sealing cover 1404, and the resistance reducing agent can be poured into the liquid storage container through the filling port 1403. When the resistance reducing agent needs to penetrate into the ground 1, the outlet valve 1405 at the bottom of the liquid storage container can be opened, so that the resistance reducing agent can be poured into the ground 1 and penetrate into the ground, thereby reducing the soil resistance.

[0031] In the above embodiment, it is divided into an above-ground part and an underground part.

[0032] In order to improve the efficiency of rainwater collection, in one embodiment, Figure 1 and Figure 2 As shown, there are multiple water diversion pipes 6, each of which is connected by a transverse pipe 13, and one of the water diversion pipes 6 is connected to the liquid storage container. In this embodiment, by providing multiple water diversion pipes 6, the efficiency of rainwater collection can be improved. Adjacent water diversion pipes 6 are connected by the transverse pipe 13 and then collected into the liquid storage container, thereby improving rainwater collection efficiency.

[0033] In order to further improve the efficiency of rainwater collection, in one embodiment, each of the water diversion pipes 6 is arranged vertically, the pipe mouth of each of the water diversion pipes 6 is arranged upward, and a traction column 10 is respectively arranged in the pipe mouth of each of the water diversion pipes 6, and the top of each traction column 10 is connected to a water collection network 11.

The water collection network 11 is a water collection network membrane, which can also be called a water collection film. The water collection network 11 is used to collect rainwater, so that rainwater can flow into the pipe mouth of the water diversion pipe 6 along the traction column 10 at the edge of the water collection network 11, thereby further improving the rainwater collection efficiency.

[0035] In one embodiment, Figure 1As shown, each of the water diversion pipes 6 is provided with a water diversion valve 12 . By providing the water diversion valve 12 , the opening and closing of the water diversion pipe 6 can be controlled.

[0036] In order to guide the water in the water diversion pipe 6 to the liquid storage container, in one embodiment, the water storage mechanism also includes a lower guide pipe 1401, and a transverse pipe 13 is connected to the lower guide pipe 1401. The lower guide pipe 1401 is arranged in a vertical direction, and the upper end of the lower guide pipe 1401 is connected to the transverse pipe 13, and the lower end of the lower guide pipe 1401 is connected to the liquid storage container.

The auxiliary mounting mechanism 7 is connected to the water diversion pipe 6 , and the grounding resistance detector 8 is arranged on the auxiliary mounting mechanism 7 .

[0038] In this embodiment, the auxiliary mounting mechanism 7 is used to support a ground resistance detector 8. The auxiliary mounting mechanism 7 is connected to the water diversion pipe 6 and can be fixed to the water diversion pipe 6. In this embodiment, the ground resistance detector 8 is model SG3000.

[0039] In one embodiment, Figure 3 As shown, the arrester grounding resistance reduction device further includes a warning mechanism 9 , which is provided on the auxiliary mounting mechanism 7 and is electrically connected to the grounding resistance detector 8 .

[0040] In this embodiment, the warning mechanism 9 includes a microcontroller 901 and a communication module. The communication module is a 4G or 5G module. The model of the microcontroller 901 is KSZ8051RNLU-TR. After the grounding resistance detector 8 detects the resistance value of the grounding resistance, the resistance data is sent to the microcontroller 901. The microcontroller 901 transmits the resistance data to the monitoring platform of the operation and maintenance personnel through the communication module. The operation and maintenance personnel can view historical data and analyze trends at any time. When it is found that the grounding resistance exceeds the alarm threshold, maintenance can be carried out in time to ensure the safe operation of electrical equipment and systems.

[0041] In addition, one end of the microcontroller 901 is electrically connected to the three sets of round steels 902 via a power line. The grounding resistance is monitored by the microcontroller 901, which facilitates real-time monitoring of the grounding resistance and facilitates subsequent maintenance.

[0042] In order to realize the installation of the warning mechanism 9 and the ground resistance detector 8, in one embodiment, see Figure 3 The auxiliary installation mechanism 7 includes a fixed circular clamp 701, a support plate and a baffle 702. The fixed circular clamp 701 is sleeved on the outside of the water diversion pipe 6. The support plate and the baffle 702 are respectively connected to the fixed circular clamp 701. The support plate and the baffle 702 are spaced apart. The ground resistance detector 8 and the warning mechanism 9 are arranged on the support plate, and the baffle 702 is arranged above the ground resistance detector 8 and the warning mechanism 9.

[0043] In this embodiment, the cross-sectional shape of the fixed circular clip 701 is circular, adaptable to the shape of the water pipe 6. The fixed circular clip 701 can be opened and is elastic, capable of clamping under its own elasticity. In this way, the fixed circular clip 701 can be easily and securely installed on the water pipe 6. The support plate supports the warning mechanism 9 and the ground resistance tester 8, making the installation of the warning mechanism 9 and the ground resistance tester 8 relatively stable. The shielding plate 702 can shield the warning mechanism 9 and the ground resistance tester 8 from wind and rain.

[0044] In some other embodiments, a threaded structure is provided on the inner surface of the fixed circular clamp 701, and the fixed circular clamp 701 is connected to the outer surface of a water pipe 6 through a threaded connection. The fixed circular clamp 701 can be installed and disassembled conveniently through the threaded connection.

[0045] In order to realize the installation of the warning mechanism 9 and the ground resistance detector 8, in another embodiment, see Figure 4 The auxiliary installation mechanism 7 includes a box body 703 and a box cover 704. An installation cavity is set in the box body 703. The ground resistance detector 8 and the warning mechanism 9 are set in the installation cavity. The box body 703 has a box opening connected to the installation cavity. The box cover 704 is rotatably connected to the box body 703 and movably closes the box opening.

[0046] In this embodiment, by installing the warning mechanism 9 and the ground resistance detector 8 in the installation cavity inside the box body 703 and sealing the box opening with the box cover 704, the warning mechanism 9 and the ground resistance detector 8 can be protected to prevent mechanical damage and avoid the influence of adverse weather.

[0047] In one embodiment, Figure 1As shown, the underground support frame includes multiple angle steels 2 and multiple cross steels 3. The multiple angle steels 2 are parallel to each other and arranged at intervals. Each cross steel 3 is perpendicular to each angle steel 2. One end of each cross steel is connected to the middle of one angle steel 2, and the other end of each cross steel is connected to the middle of another angle steel 2. Each cross steel 3 is arranged around the outside of the resistance reduction mechanism 4, and the two ends of the resistance reduction mechanism 4 are respectively connected to the two oppositely arranged cross steels.

[0048] In this embodiment, the number of angle steels 2 is four, and the number of cross steels 3 is four. The four cross steels 3 are arranged in a rectangular shape, and the angle steels 2 are located at the four diagonal corners of the rectangle. Specifically, the extension direction of the angle steel 2 is arranged along the vertical direction, and the cross steel 3 is arranged along the horizontal direction. In this way, the angle steel 2 can be made more stable through the connection of the cross steel 3. In some embodiments, a threaded structure is provided in the middle part of the angle steel 2, and screw connection parts are respectively provided at both ends of the cross steel 3. The screw connection parts are provided with screw holes. In this way, the angle steel 2 is passed through the screw hole, and the threaded structure in the middle part of the angle steel 2 is screwed to the side wall of the screw hole, thereby realizing a stable connection between the cross steel 3 and the angle steel 2. In this embodiment, both the angle steel 2 and the cross steel 3 have conductive properties and can conduct electricity to the resistance reduction mechanism 4. The material of the cross steel 3 and the angle steel 2 is steel, which has high strength. With the support of the cross steel 3 and the angle steel 2, the installation of the resistance reduction mechanism 4 can be made more stable.

[0049] In one embodiment, Figure 2 As shown, the resistance reduction mechanism 4 includes a graphite grounding block 401 and a connecting steel frame 402. The two ends of the connecting steel frame 402 are respectively connected to the two oppositely arranged horizontal steels. The connecting steel frame 402 includes a plurality of first brackets and second brackets vertically connected to each other. The first bracket and the second bracket are connected to each other, and an installation space is formed inside. A graphite grounding block 401 is set in each of the installation spaces, and the graphite grounding block 401 is connected to the adjacent first bracket and the second bracket.

[0050] In this embodiment, the first bracket and the second bracket are made of steel, have conductive properties, and have high strength, and can well support the graphite grounding block 401. When the graphite grounding block 401 is installed underground, backfill soil is placed on the upper surface of the graphite grounding block 401. The graphite powder and backfill soil increase the conductivity of the soil, thereby effectively reducing the grounding resistance.

[0051] In order to achieve electrical connection with the arrester, in one embodiment, please refer again to Figure 2 The grounding mechanism 5 includes a grounding wire 501, a grounding flat iron 502 and a lower lead of the lightning arrester. One end of the grounding wire 501 is connected to one of the angle steels 2, the other end of the grounding wire 501 is connected to one end of the grounding flat iron 502, and the other end of the grounding flat iron 502 is connected to one end of the lower lead of the lightning arrester.

[0052] In this embodiment, threaded holes are respectively provided at both ends of the grounding flat iron 502. One end of the grounding wire 501 is screwed to the side wall of the threaded hole at one end of the grounding flat iron 502. One end of the lower lead of the lightning arrester is screwed to the side wall of the threaded hole at the other end of the grounding flat iron 502. The other end of the lower lead of the lightning arrester is used to connect to the grounding lead of the lightning arrester. The threaded connection allows for convenient connection of the grounding wire 501, the grounding flat iron 502, and the lower lead of the lightning arrester. In order to achieve the connection between the grounding wire 501 and the angle steel 2, in one embodiment, the grounding wire 501 is welded to the angle steel 2. The connection between the grounding wire 501 and the angle steel 2 is achieved by welding, which can make the connection between the grounding wire 501 and the angle steel 2 more stable.
