Description

Technical Field

[0001] This invention relates to the field of equipment grounding detection technology, and in particular to a combined grounding detection device and method based on real-time detection technology. Background Technology

[0002] In power industry testing and maintenance, the grounding reliability of testing equipment and power tools is directly related to the personal safety of operators, the stability of equipment operation, and the accuracy of test data. Currently, the grounding methods used in power operations are mainly of two types: single-point independent grounding and simple centralized grounding. (1) Single-point independent grounding: Each piece of equipment is connected to a separate grounding electrode and grounded through an independent grounding wire. (2) Simple centralized grounding: The grounding wires of multiple devices are connected together through a common grounding device and then connected to the grounding electrode. The existing technology has the following technical defects.

[0003] No real-time monitoring of grounding status: Existing devices cannot provide real-time feedback on the grounding continuity status of each device. If the grounding wire is loose, has poor contact, or the grounding electrode fails, it is difficult for operators to detect, which may lead to risks such as electric shock, equipment damage, or distorted test data.

[0004] Disorganized management of multiple devices: Simple centralized grounding devices lack branch identification function. When multiple devices are connected at the same time, it is impossible to quickly locate the faulty branch, resulting in low troubleshooting efficiency; single-point independent grounding leads to messy grounding wires, increasing safety hazards such as tripping and entanglement at the work site.

[0005] Delayed alarm response: Traditional devices rely solely on manual inspections to confirm the grounding status. Grounding faults during inspection intervals cannot be detected in a timely manner, and there is no active alarm mechanism, resulting in untimely fault handling.

[0006] Limited adaptability: The grounding resistance threshold of existing devices is fixed, and the grounding standard cannot be adjusted according to different test types (such as high voltage withstand test, insulation test) and equipment specifications, resulting in insufficient versatility.

[0007] Lack of data traceability: The lack of grounding status history record function makes it impossible to trace changes in grounding parameters during operation, which is not conducive to fault tracing and operation quality control.

[0008] In summary, existing technologies focus on achieving "grounding connection" but fail to fully consider the core requirement of "grounding reliability monitoring," and lack integrated design for real-time detection modules. The structural design is inadequate; the integrated grounding device lacks independent branch detection units, making it impossible to distinguish the grounding status of each device; the single-point grounding device lacks a unified management interface, making it difficult to achieve collaborative monitoring of multiple devices; and the technology integration is lacking, failing to incorporate data transmission and other technologies, thus failing to achieve real-time feedback and monitoring of grounding status, and relying on manual intervention leading to delayed response. Summary of the Invention

The detection unit includes multiple branch grounding ports 4 for connecting to the grounding wire of the device under test for grounding detection. The branch grounding ports are correspondingly connected to the detection ports 12 of the detection host 1. The detection host 1 has a main grounding port 11, which is connected to one end of a main grounding wire 2. The main grounding wire 2 is wound around the winding part / winding column of the spool 100. The other end of the main grounding wire 2 is connected to a grounding bar clamp 3 for convenient connection and testing with the grounding electrode.

The spool body is composed of two side plates and a winding post connected together, and a handle is connected to the other side plate for easy hand movement.

[0036] According to an embodiment of this application, the surface of the side plate 5 is provided with an alarm module or feedback module for alarming when the detection result is abnormal and indicating when it is normal. The alarm module uses sound and / or light alarm methods to alarm, including a buzzer 6 and an LED indicator.

[0037] According to an embodiment of this application, the LED indicator includes a green LED indicator 8 and a red LED indicator 7. When providing feedback and alarm according to an embodiment of this application, the green indicator 9 remains constantly lit when the detection is normal, and the red indicator 7 flashes when the detection is abnormal, while the buzzer 6 provides alarm feedback.

[0038] According to an embodiment of this application, the detection host (i.e., central host) 1 includes a processor, a detection module connected to the processor, and a memory, the memory being used to store detection data; the detection module includes a galvanometer 9 and a voltage sensor 10; one detection terminal 12 is connected to one galvanometer 9 and one voltage sensor 10 to form a detection loop, the detection loop being connected to a preset port of the processor (microcontroller); the galvanometer 9 is used to detect the current in the detection loop, and the voltage sensor 10 is used to detect the voltage across the detection loop; when the grounding wire of the device under test is connected to the detection port 12, the current and voltage at this time can be detected through the detection loop, and the magnitude of the grounding resistance of the device can be calculated.

[0039] The current sensor is model ACS712, the voltage sensor is model LV25-P, and the processor serves as the central control module.

[0040] Specifically, the real-time data stored in the memory can also be uploaded to the monitoring terminal via a wireless transmission module, and historical data can be stored locally.

[0041] According to an embodiment of this application, the processor is a microcontroller, specifically an STM32F103 microcontroller, which is connected to a power module / power management unit and a flexible touchscreen / LCD display. The flexible touchscreen / LCD display is used to set ground resistance threshold, current abnormality threshold, and voltage abnormality threshold.

[0042] According to an embodiment of this application, the power supply module includes a battery module 13 (e.g., 9V DC) and a boost circuit module (not shown, but an internal circuit of a microcontroller) connected in parallel with the battery module. The boost circuit module is used to boost the output voltage of the battery module 13 to a preset voltage (e.g., 24V) to power the detection host and its various power-consuming modules.

[0043] According to an embodiment of this application, the main grounding wire 2 is made of multi-strand transparent soft copper wire. During field operation, it is connected to the fixed grounding electrode via the grounding bar clamp 3 for grounding detection. It is connected to the main grounding port 11 of the detection host 1. Figure 4 As shown.

[0044] According to an embodiment of this application, the branch grounding port 4 is a hot-swappable port, and the tails of the plurality of branch grounding ports are connected to the corresponding detection ports 12 of the detection host 1. For example, Figure 4 An example is shown that includes four branch grounding ports and four detection ports 12.

[0045] This application also provides a method for detecting grounding based on real-time detection technology, which is performed using the aforementioned grounding detection device based on real-time detection technology, and includes the following steps:

[0046] Move the integrated grounding device to the target location and connect the main grounding wire to the fixed grounding electrode on site;

[0047] Insert the grounding wire of the device to be tested into the branch grounding port;

[0048] The system detects that the host is powered on and initialized, which means that the system or device's modules are initialized upon power-up.

[0049] The system detects abnormal thresholds for current, voltage, and grounding resistance input to the host's touchscreen.

[0050] During the detection process, data on current I, voltage U, and grounding resistance r are collected in real time and compared with threshold values.

[0051] An alarm is triggered via the alarm module based on the threshold comparison results.

[0052] According to an embodiment of this application, during the detection process, the detection module detects current and voltage data in real time, and the grounding resistance calculation unit calculates the grounding resistance based on the detected current and voltage. A threshold setting comparison unit compares the detected current, voltage, and grounding resistance thresholds, and issues an indication or alarm based on the comparison result. The grounding resistance calculation unit and the threshold setting comparison unit are configured using software programs within the detection host.

[0053] As an example, the specific grounding test procedure for the equipment is as follows:

[0054] (1) Connect the grounding bar clamp of the main grounding wire to the grounding electrode. The grounding electrode is buried at a depth of ≥2m, and the initial value of the grounding resistance of the equipment under test is ≤4Ω.

[0055] (2) Install the battery module (e.g., 9V DC), start the central control module, and set the device's grounding resistance threshold (default 1.5Ω), current abnormality threshold (default 5A), and voltage abnormality threshold (default 10V) through the display screen.

[0056] (3) Connect the multiple devices to be tested to each branch grounding port through their grounding wires, and check whether the grounding port of each branch displays the connected mark on the display screen;

[0057] (4) Simulate grounding fault: Disconnect the grounding wire of one of the devices to be tested, and observe whether the corresponding branch grounding port displays "connection abnormal" on the display screen and whether the buzzer sounds an alarm.

[0058] (5) Adjust the grounding resistance: Change the grounding resistance of a branch of the device under test to 10Ω (exceeding the grounding resistance threshold) by connecting a series resistor, and verify whether the device can accurately detect and alarm;

[0059] (6) Test data transmission: Verify whether the transmission and local storage functions are normal by querying the status data of the grounding port of each branch device under test;

[0060] (7) Run continuously for 24 hours, record the working status of each module, and ensure that there are no abnormal lags, data loss, or other issues.

[0061] The grounding device of the present invention has the following significant advantages:

[0062] (I) Improved real-time monitoring capabilities: Existing technologies lack real-time detection functions, and grounding fault detection relies on manual inspection, with an average detection time of ≥1 minute; the detection response time of this invention is ≤0.3 seconds, and the fault alarm delay is ≤0.5 seconds, enabling immediate detection of grounding faults and reducing fault detection time by more than 99%.

[0063] (II) Grounding Reliability Guarantee: Existing technologies cannot monitor grounding resistance in real time, which poses a hidden risk of poor grounding and has an operational safety hazard rate of about 3.2%. The grounding resistance detection accuracy of this invention reaches ±1Ω, and it can provide real-time early warning of resistance exceeding the standard. Combined with the pluggable port design, the grounding failure risk rate is reduced to below 1%, and the safety guarantee factor is improved by 32 times.

[0064] (III) Multi-device management efficiency: When multiple devices are grounded in the existing technology, fault branch troubleshooting requires testing one by one, with an average troubleshooting time of ≥10 minutes; the present invention accurately locates fault branches through branch-corresponding indicator lights and alarm information, with a troubleshooting time of ≤10 seconds, improving work efficiency by 60 times.

[0065] (iv) Universality and adaptability: Existing technologies have fixed grounding resistance, which are only suitable for a single operating scenario, with an adaptability rate of about 40%; the grounding resistance threshold of this invention can be customized within the range of 0-100Ω, supporting multiple scenarios such as high-voltage testing and equipment maintenance, with an adaptability rate of 100%.

[0066] (V) Data traceability and control: Existing technology has no data storage function, cannot trace the history of grounding status, and has great difficulty in tracing the source of faults; it supports local data storage and query, and the historical data traceability rate reaches 100%, which facilitates operation quality control and fault analysis.

[0067] (vi) Adopting IP65 waterproof design, it is suitable for harsh outdoor working environments and has a service life of ≥8 years (the average service life of existing devices is about 5 years); it has audible and visual alarms with 100% alarm coverage, avoiding the omission of faults due to long working distances; it supports hot-swapping of branch grounding terminals, so there is no need to disconnect the main grounding when switching equipment, improving the continuity of operation by 40%.
