Description

Technical Field

[0001] This application relates to the field of grounding technology, and in particular to a rent reduction and resistance stabilization system and method. Background Technology

[0002] Fluctuations in the grounding resistance of a grounding device, i.e., unstable grounding resistance (sometimes high, sometimes low), directly undermine the reliability of the grounding system, significantly reduce the effectiveness of various safety protection measures, and greatly increase the risk of electric shock, equipment damage, and power system accidents.

[0003] Precision equipment, in particular, has extremely high requirements for grounding resistance stability, as the impact of grounding resistance instability on such equipment is often more insidious and fatal than that on ordinary electrical equipment. After precision equipment has undergone laboratory testing or EMC commissioning within a specific time period, grounding resistance instability can exacerbate critical mechanisms such as parameter drift, common-mode noise, and ground loop currents. This can lead to inaccurate measurements, data corruption, chronic component damage, occasional system downtime, and even fatal safety accidents. The hazards are insidious, highly destructive, and extremely costly to repair; therefore, grounding resistance stability and low impedance must be considered the core lifeline of precision equipment infrastructure.

[0004] Grounding resistance fluctuations are not caused by a single factor, but are the result of a combination of internal and external factors (such as corrosion, continuous loosening, and seasonal drought). The loss of conductive ions from the soil, moisture changes, and corrosion are the three most common and primary causes of grounding resistance fluctuations and increases. Existing technologies use periodic monitoring of the grounding resistance and connection status of grounding devices to identify and assess grounding problems or risks. However, due to the periodic nature of these monitoring efforts, grounding resistance fluctuations during operation cannot be monitored and addressed in a timely manner, thus creating potential safety hazards. Summary of the Invention

The second instruction stops when the soil moisture content reaches the second moisture content threshold. When the soil pH value is less than the acid threshold or greater than the alkaline threshold, a third instruction is generated to replenish the soil at the location of the grounding device with water-soluble compounds of the opposite pH value; otherwise, the soil pH value is continuously monitored. The stopping condition for the third instruction is that the soil pH value is greater than or equal to the acid threshold and less than or equal to the alkaline threshold. And the fourth directive to replenish the soil at the location of the grounding device with a specified amount of metal corrosion-resistant passivating agent once a year.

The input end of the delivery pump is connected to the solenoid valves on the first zone, second zone, third zone, fourth zone, and tap water pipe, respectively, and its output end is connected to the guide pipe. It is used to pump neutral conductive ions, tap water, acidic or alkaline water-soluble compounds, and / or metal anti-corrosion passivating agents to the soil at the location of the grounding device according to the resistance reduction and resistance stabilization decision. The guide pipe is located in the soil at the location of the grounding device. The guide pipe has several pressure equalization seepage holes. Each pressure equalization seepage hole is used to replenish the soil at the location of the grounding device with neutral conductive ions, tap water, acidic or alkaline water-soluble compounds, and / or metal anti-corrosion passivating agents.

[0013] Preferably, the plurality of pressure equalizing seepage holes are distributed from sparse to dense on the guide pipe, with the sparsely distributed end being the end of the guide pipe near the delivery pump and the densely distributed end being the end of the guide pipe far from the delivery pump.

[0014] Preferably, the guide tube is made of PPR material.

[0015] On the other hand, a rent reduction and resistance stabilization method applicable to the above-mentioned rent reduction and resistance stabilization system is provided, the method comprising: S1: Monitor the grounding resistance value of the grounding device and determine whether the grounding resistance value exceeds the grounding resistance threshold designed for the grounding device. If yes, proceed to step S2; otherwise, continue monitoring the grounding resistance value of the grounding device. S2: Determine whether the soil resistivity monitored at the location of the grounding device exceeds the resistivity threshold. If yes, generate the first instruction to replenish neutral conductive ions in the soil at the location of the grounding device; otherwise, continue to monitor the soil resistivity. If the soil moisture content at the location of the grounding device is lower than the first moisture content threshold, a second instruction is generated to inject tap water into the soil at the location of the grounding device; otherwise, the soil moisture content is continuously monitored. If the soil pH value monitored at the location of the grounding device is less than the acid threshold or greater than the alkaline threshold, a third instruction is generated to replenish the soil at the location of the grounding device with a water-soluble compound of the opposite pH; otherwise, the soil pH value is continuously monitored. S3: Adjust the resistivity, humidity and / or pH of the soil at the location of the grounding device according to the first, second and / or third instructions.

[0016] Beneficial effects: By real-time monitoring and judgment of the grounding resistance value of the grounding device, when the grounding resistance value is abnormal, a rent reduction and resistance stabilization decision is determined based on the soil resistivity, soil moisture content, and soil pH value at the location of the grounding device. Then, the rent reduction and resistance stabilization unit adjusts the resistivity, humidity, and / or pH of the soil at the location of the grounding device according to the rent reduction and resistance stabilization decision. This can promptly detect problems and make timely adjustments, stabilizing the grounding resistance of the grounding device. By adding a limited amount of metal anti-corrosion passivating agent to the soil at the location of the grounding device once a year, the safety hazards of grounding resistance fluctuations during the operation of the grounding device are eliminated and the service life of the grounding device is extended.

Detailed Implementation

[0022] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] The grounding resistance of a grounding device mainly consists of the grounding electrode resistance, the contact resistance between the grounding electrode and the soil, and the soil current dissipation resistance. Among these, the contact resistance between the grounding electrode and the soil and the soil resistivity (which is inversely proportional to the concentration of neutral conductive ions in the soil) play a decisive role. Soil resistivity is affected by factors such as soil moisture and salinity. Therefore, this embodiment provides a resistance reduction and stabilization system that monitors the grounding resistance of the grounding device and soil moisture in real time to promptly detect and address problems, thus avoiding potential safety hazards.

[0025] like Figure 1 As shown, a rent reduction and resistance stabilization system includes: Grounding device, online grounding resistance monitoring unit, online soil moisture monitoring unit, control platform, and resistance reduction and stabilization unit; The grounding device is located underground; The online grounding resistance monitoring unit is connected to the grounding device and the control platform respectively, and is used to monitor the grounding resistance value of the grounding device and transmit the grounding resistance value to the control platform. The soil moisture online monitoring unit is located at the grounding device and connected to the control platform. It is used to monitor the soil resistivity, soil moisture content, and soil pH value at the location of the grounding device, and transmit the soil resistivity, soil moisture content, and soil pH value to the control platform. The control platform is used to determine the resistance reduction and stabilization decision based on the grounding resistance value, soil resistivity, soil moisture content, and soil pH value, and transmit the resistance reduction and stabilization decision to the resistance reduction and stabilization unit. The resistance reduction and stabilization unit is used to adjust the resistivity, humidity and / or pH of the soil at the location of the grounding device according to the resistance reduction and stabilization decision.

[0026] In this embodiment, the grounding device is arranged underground in the form of a grounding grid.

[0027] Furthermore, the online grounding resistance monitoring unit includes an online grounding resistance monitoring instrument, which is connected to the grounding device and the control platform respectively. It is used to periodically monitor the grounding resistance of the grounding device according to a set time interval and transmit the grounding resistance monitoring signal to the control platform.

[0028] Furthermore, the online soil moisture monitoring unit includes a soil resistivity sensor, a soil moisture sensor, a soil pH sensor, and a data acquisition module. The soil resistivity sensor, soil moisture sensor, and soil pH sensor are all located at the grounding device's location, and each of their output terminals is connected to the data acquisition module. The output terminal of the data acquisition module is connected to the control platform. The soil resistivity sensor monitors the soil resistivity signal at the grounding device's location, the soil moisture sensor monitors the soil water content signal at the grounding device's location, and the soil pH sensor monitors the soil pH signal at the grounding device's location. The data acquisition module converts the received soil resistivity signal, soil water content signal, and soil pH signal into data and transmits the converted data to the control platform.

[0029] In this embodiment, the rent reduction and resistance stabilization decision includes: When the grounding resistance value exceeds the grounding resistance threshold designed for the grounding device, determine whether the soil resistivity, soil moisture content and soil pH value exceed the corresponding thresholds respectively; otherwise, continue to monitor the grounding resistance value. When the soil resistivity exceeds the resistivity threshold, a first instruction is generated to replenish neutral conductive ions in the soil at the location of the grounding device; otherwise, the soil resistivity is continuously monitored. The first instruction stops when the soil resistivity reaches the lower resistivity limit (i.e., the concentration of neutral conductive ions in the soil reaches the upper limit of the ion concentration under the limited flow rate).

[0030] When the soil moisture content is less than the first moisture content threshold (15%RH), a second instruction is generated to inject tap water into the soil at the location of the grounding device; otherwise, the soil moisture content is continuously monitored. The second instruction stops when the soil moisture content reaches the second moisture content threshold (25%RH).

[0031] The grounding material of the grounding device is generally copper, copper-clad steel or galvanized steel, and its corrosion-resistant pH value is in the range of [7,12]. Therefore, when the soil pH value is less than the acid threshold (pH=7) or greater than the alkaline threshold (pH=12), a third instruction is generated to replenish the soil at the location of the grounding device with water-soluble compounds of the opposite pH. Otherwise, the soil pH value is continuously monitored. The stopping condition of the third instruction is that the soil pH value is greater than or equal to the acid threshold and less than or equal to the alkaline threshold.

[0032] And the fourth directive to replenish the soil at the location of the grounding device with a specified amount of metal corrosion-resistant passivating agent once a year.

[0033] This embodiment also includes: when the soil moisture content is too high, soil saturation leads to loosening, and the decreased binding force between particles can cause geological disasters such as landslides, mudslides, and ground subsidence. Therefore, when the soil moisture content exceeds the third moisture content threshold (40% RH), all liquid replenishment is stopped, and a geological disaster warning is issued. Furthermore, if... Figure 2 When the concentration of neutral conductive ions in the first zone monitored by the medium concentration sensor is lower than the lower limit, a lack of conductive ions alarm is issued; when the soil moisture content exceeds the third moisture content threshold and the ion concentration reaches the upper limit of the ion concentration under the limited flow rate, it is determined that the grounding device is rusted or broken, and a grounding device failure alarm is issued.

[0034] Furthermore, the resistance reduction and stabilization unit includes a liquid storage tank, a delivery pump, and a flow guide pipe; The storage tank is equipped with a first zone for loading neutral conductive ions, a second zone for loading acidic water-soluble compounds, a third zone for loading alkaline water-soluble compounds, a fourth zone for loading metal corrosion-resistant passivating agents, and solenoid valves that control the flow of each liquid based on resistance reduction and stabilization decisions. The input end of the delivery pump is connected to the solenoid valves on the first, second, third, and fourth zones and the tap water pipe, respectively, and its output end is connected to the guide pipe. It is used to pump neutral conductive ions, tap water, acidic or alkaline water-soluble compounds, and / or metal corrosion-resistant passivating agents to the soil at the location of the grounding device according to the resistance reduction and stabilization decision.

[0035] The guide pipe is located in the soil at the location of the grounding device. The guide pipe has several pressure equalization seepage holes. Each pressure equalization seepage hole is used to replenish the soil at the location of the grounding device with neutral conductive ions, tap water, acidic or alkaline water-soluble compounds, and / or metal anti-corrosion passivating agents.

[0036] Upon receiving the first, second, and / or third command, the corresponding solenoid valve in the designated area is opened, allowing the corresponding liquid to flow out and then be replenished into the soil at the location of the grounding device via a delivery pump and guide pipe. During soil adjustment, if the soil resistivity reaches the lower limit, the soil moisture content reaches the second moisture content threshold, or the soil pH value is greater than or equal to the acidic threshold but less than or equal to the alkaline threshold, all open solenoid valves and delivery pumps are closed, and soil adjustment is stopped. If the grounding resistance value is still greater than the grounding resistance threshold designed for the grounding device, a grounding device failure alarm is issued.

[0037] In this embodiment, the guide pipe is a PPR material pipe, and a number of pressure equalization seepage holes are distributed on the guide pipe from sparse to dense. The sparsely distributed end is the end of the guide pipe near the delivery pump, and the densely distributed end is the end of the guide pipe far from the delivery pump.

[0038] like Figure 2 As shown, this embodiment provides a resistance-reducing and resistance-stabilizing structure for example, taking soil resistivity anomaly and supplementing neutral conductive ions. Its workflow is as follows: When the online grounding resistance monitoring unit detects that the grounding resistance value of the grounding device 1 exceeds the grounding resistance threshold designed for the grounding device, the soil resistivity sensor 21 monitors the soil resistivity at the location of the grounding device 1. The data acquisition module 22 receives the soil resistivity signal and converts it into data, transmits the converted data to the control platform, and determines whether the soil resistivity exceeds the resistivity threshold. If so, the control platform generates a first instruction to replenish neutral conductive ions in the soil at the location of the grounding device; otherwise, it continues to monitor the soil resistivity. The resistance reduction and stabilization unit adjusts the soil resistivity at the location of the grounding device according to the first instruction. Specifically, the first solenoid valve 5 and the second solenoid valve 6 are opened according to the first instruction, releasing neutral conductive ions in the first zone 3 and dissolving them in the filtered tap water in the tap water pipe 4. The tap water containing the dissolved conductive ions flows through the pipe to the delivery pump 7, and then the delivery pump 7 pumps the tap water containing the dissolved conductive ions through the guide pipe 8 with pressure equalization seepage holes into the soil at the location of the grounding device to reduce the soil resistivity at the location of the grounding device, thereby achieving resistance reduction and stabilization. During soil conditioning, the flow rate of tap water containing dissolved conductive ions in the pipeline is monitored by the flow rate sensor 9. When the flow rate exceeds the limit, the signal is fed back to the control platform. The control platform controls the opening degree of the first solenoid valve 5 and / or the second solenoid valve 6 to keep the flow rate in the pipeline within the limit. At the same time, the concentration of neutral conductive ions in the first zone 3 is monitored by the concentration sensor 10. When the concentration of neutral conductive ions in the first zone 3 is lower than the lower limit, a conductive ion deficiency alarm is issued.

[0039] like Figure 3As shown, this embodiment provides a rent reduction and resistance stabilization method applicable to the above-mentioned rent reduction and resistance stabilization system. The method includes: S1: Monitor the grounding resistance value of the grounding device and determine whether the grounding resistance value exceeds the grounding resistance threshold designed for the grounding device. If yes, proceed to step S2; otherwise, continue monitoring the grounding resistance value of the grounding device. S2: Determine whether the soil resistivity monitored at the location of the grounding device exceeds the resistivity threshold. If yes, generate the first instruction to replenish neutral conductive ions in the soil at the location of the grounding device; otherwise, continue to monitor the soil resistivity. If the soil moisture content at the location of the grounding device is lower than the first moisture content threshold, a second instruction is generated to inject tap water into the soil at the location of the grounding device; otherwise, the soil moisture content is continuously monitored. If the soil pH value monitored at the location of the grounding device is less than the acid threshold or greater than the alkaline threshold, a third instruction is generated to replenish the soil at the location of the grounding device with a water-soluble compound of the opposite pH; otherwise, the soil pH value is continuously monitored. S3: Adjust the resistivity, humidity and / or pH of the soil at the location of the grounding device according to the first, second and / or third instructions. S4: Repeat steps S1-S3 until the soil resistivity reaches the lower limit of resistivity, the soil moisture content reaches the second moisture content threshold, and the soil pH value is greater than or equal to the acid threshold and less than or equal to the alkaline threshold, then stop soil adjustment; if the grounding resistance value is still greater than the grounding resistance threshold designed for the grounding device, then issue a grounding device failure alarm.

[0040] The rent reduction and resistance stabilization system and method provided in this embodiment have the following beneficial effects: By real-time monitoring and judgment of the grounding resistance value of the grounding device, when the grounding resistance value is abnormal, a rent reduction and stabilization decision is determined based on the soil resistivity, soil moisture content, and soil pH value at the location of the grounding device. Then, the rent reduction and stabilization unit adjusts the resistivity, humidity, and / or pH of the soil at the location of the grounding device according to the rent reduction and stabilization decision. This allows for timely detection and adjustment of problems, stabilizing the grounding resistance of the grounding device. By adding a limited amount of metal anti-corrosion passivating agent to the soil at the location of the grounding device once a year, the safety hazards of grounding resistance fluctuations during the operation of the grounding device are eliminated and the service life of the grounding device is extended.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
