Obviously, the described embodiment is only a part of the embodiment of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] See also Figure 1 , Figure 1 It is a schematic diagram of the framework of an embodiment of a high-voltage cable grounding loop resistance precision detection platform of the present application.

[0021] In this embodiment, the system includes an acquisition module 11, a response module 12, an extraction module 13 and an adjustment module 14, wherein the acquisition module 11 is used to acquire the electrical characteristics of the circuit to be tested; the response module 12 is used to inject the test signal into the circuit to be tested in response to the electrical characteristics currently having a matching corresponding test signal in a preset database, and monitor the test signal of the circuit to be tested in real time; the extraction module 13 is used to extract at least one electrical characterization value of the test signal, and match the corresponding adjustment parameter according to the electrical characterization value; the adjustment module 14 is used to adjust the test signal according to the adjustment parameter.

[0022] The above scheme first obtains the electrical characteristics of the circuit to be tested through the acquisition module 11, and the response module 12 searches for the test signal matching these electrical characteristics in the preset database to realize the automatic and intelligent matching of the test signal. The matched appropriate test signal is injected into the circuit to be tested, and the test signal of the circuit is detected in real time. The corresponding adjustment parameters are matched according to the characteristics of the test signal to ensure that the circuit changes can be quickly responded to during the test, thereby improving the efficiency of the test.

[0023] In some embodiments, the acquisition module 11 is further used to match corresponding specification information from a preset information summary table according to the identity information of the circuit to be tested, and to obtain current data and voltage data of the current circuit to be tested.

[0024] Specifically, the identity information of the circuit to be tested may include the number or location identification of the circuit to be tested. For example, the identity information of the circuit to be tested may be obtained by reading the identity sensing area or identity identification plate of the circuit to be tested through a sensor or a scanning device. The information summary table may be a pre-established database or table, and the information summary table at least includes the identity information of each circuit and its corresponding specification information. The specification information may include the resistance range, current carrying capacity, voltage level, etc. of the circuit. To obtain the current data and voltage data of the current circuit to be tested, the current and voltage of the circuit to be tested may be measured by a current sensor and a voltage sensor respectively, or the current current data and voltage data of the circuit to be tested may be called from the terminal control system.

[0025] In some embodiments, the response module 12 is also used to match the first path node of the corresponding specification information in a preset database based on the specification information in the electrical characteristics, and use the current current data and voltage data of the circuit to be tested to match the corresponding test signal under the first path node.

[0026] Specifically, the response module 12 first locates the first path node corresponding to the specification information in the database preset by the specification information. The first path node represents the entry point of all data related to the specification information in the database. The response module 12 uses the current current data and voltage data of the circuit to be tested to further search for matching test signals under the first path node to find the test signal that best matches the current state of the circuit to be tested. Based on the electrical characteristics of the circuit to be tested, the most suitable test signal is efficiently matched in the preset database, which improves the accuracy and efficiency of the loop resistance test and reduces the cost and risk of manual intervention.

[0027] In some specific embodiments, it is necessary to perform a resistance test on a 110kV high-voltage cable grounding loop. The length of the cable is 260 meters, and a single-ended grounding form is adopted. It is known that the DC resistance of the metal sheath can be estimated at 50mΩ / km. During the detection, the acquisition module 11 obtains the electrical characteristics of the circuit to be tested, the voltage level of the cable: 110kV, the length: 260 meters, the grounding form: single-ended grounding, and measures the current voltage data and current data of the cable through sensors and other forms. The response module 12 matches the first path node in a preset database based on the specification information (voltage level, length, grounding form) in the electrical characteristics. Then, using the current current data of the circuit to be tested, assuming it is 100A, and the voltage data, assuming it is 6kV, further search for matching test signals under the first path node. Each test signal corresponds to a specific current range and voltage range. The response module can use the test signal corresponding to the current range and voltage range closest to the current current data and the current voltage data as the matching test signal.

[0028] In some embodiments, when the system detects that there is no test signal in the preset database that matches the electrical characteristics of the current circuit to be tested, the response module 12 is also used to: create a database object for the electrical characteristics in response to the electrical characteristics currently not having a matching corresponding test signal in the preset database; and add the actual test signal of the electrical characteristics to the database object of the electrical characteristics.

[0029] Specifically, adding the test signals and related data obtained during the actual test process to the newly created database object can continuously expand and improve the database, thereby improving the adaptability and accuracy of the system.

[0030] In some embodiments, the response module 12 is also used to read the test signal and the test data corresponding to each test signal from the test process of at least one circuit to be tested corresponding to the electrical characteristic; and store the read test signal and the test data corresponding to each test signal in the database object of the electrical characteristic.

[0031] In addition, considering that there may be failures during the test process, in some specific embodiments, the test data added to the new database object is screened, the test data with successful test results is screened, and the screened test data is added to the preset database for subsequent testing. Ensure that the data in the preset database are verified and valid data to improve the accuracy and efficiency of the test. Specifically, the test data includes the electrical characterization values ​​of the circuit to be tested during the test process, and the safety threshold range of the electrical characterization values ​​can be determined based on the electrical characterization values ​​of the circuit to be tested during the test process of multiple circuits with the same specification information, and added to the preset database.

[0032] In some embodiments, the extraction module 13 is further configured to compare each electrical characterization value with a preset corresponding electrical characterization value safety threshold range.

[0033] Specifically, the electrical characterization value may include a voltage value, a current value, a resistance value, etc. The safety threshold range of the electrical characterization value may be determined based on factors such as equipment specifications, safety standards, and past experience.

[0034] In some embodiments, the electrical characterization value includes a maximum voltage value, and the safety threshold range of the electrical characterization value includes a voltage safety threshold range; the adjustment module 14 is also used to reduce the voltage value of the test signal in response to the maximum voltage value being higher than the voltage safety threshold range.

[0035] Specifically, in the test signal monitored in real time, the extraction module 13 will pay attention to and record the highest voltage value, and compare the recorded highest voltage value with the preset voltage safety threshold range. If the highest voltage value is higher than the upper limit of the voltage safety threshold range, the adjustment module 14 will reduce the voltage value of the test signal to prevent equipment damage or safety accidents. The adjusted test signal is re-injected into the circuit to be tested, and the test signal is continuously monitored to verify the adjustment effect.

[0036] In some embodiments, the electrical characterization value includes a minimum voltage value, and the safety threshold range of the electrical characterization value includes a voltage safety threshold range; the adjustment module 14 is further configured to increase the voltage value of the test signal in response to the minimum voltage value being lower than the voltage safety threshold range.

[0037] Specifically, in the test signal monitored in real time, the extraction module 13 will also pay attention to and record the lowest voltage value, and compare the recorded lowest voltage value with the preset voltage safety threshold range. If the lowest voltage value is lower than the lower limit of the voltage safety threshold range, the adjustment module 14 will increase the voltage value of the test signal to ensure the effectiveness and accuracy of the test, and re-inject the adjusted test signal into the circuit to be tested, and continue to monitor the test signal.

[0038] In some specific embodiments, a 110kV high-voltage cable grounding loop has a length of 300 meters and adopts a single-ended grounding form. First, the acquisition module 11 is used to obtain the electrical characteristics of the circuit to be tested. The electrical characteristics include: the voltage level of the cable is 110kV, the length is 300 meters, the grounding form is single-ended grounding, and the current current data obtained by real-time measurement by the sensor is 120A, and the voltage data is 6.5kV. The response module 12 will search for a matching test signal in a preset database according to the electrical characteristics. First, the first path node in the preset database is located by the specification information such as voltage level, length and grounding form. Then, the current data 120A and the voltage data 6.5kV currently measured are used to search for a matching test signal under the first path node. Assume that there is a test signal in the preset database, and its applicable current range is 100A to 150A and the voltage range is 6kV to 7kV. The response module 12 will use this test signal as the test signal that best matches the current state of the circuit to be tested, and inject it into the circuit to be tested. After the test signal is injected, the extraction module 13 will monitor the test signal of the circuit to be tested in real time and extract at least one electrical characterization value. In this embodiment, the electrical characterization value includes a maximum voltage value and a minimum voltage value. The maximum voltage value recorded by the extraction module 13 is 6.8kV, and the preset voltage safety threshold range is 6kV to 6.6kV. Since the maximum voltage value of 6.8kV is higher than the upper limit of the voltage safety threshold range of 6.6kV, the adjustment module 14 will respond immediately and reduce the voltage value of the test signal to prevent equipment damage or safety accidents. The adjustment module 14 can reduce the voltage value of the test signal to 6.5kV or lower, and re-inject it into the circuit to be tested for continued monitoring. If the minimum voltage value recorded by the extraction module 13 is lower than the lower limit of the voltage safety threshold range, the adjustment module 14 will also increase the voltage value of the test signal accordingly to ensure the effectiveness and accuracy of the test. Through the real-time monitoring of the electrical characterization value and the precise adjustment of the test signal by the adjustment module 14, the accuracy and safety of the high-voltage cable grounding loop resistance test are ensured, and accurate detection is achieved.

[0039] Furthermore, the degree of adjustment by the adjustment module 14 may be associated with the degree to which the electrical characterization value exceeds the threshold range. The greater the value by which the electrical characterization value exceeds the threshold range, the greater the magnitude of adjustment by the adjustment module 14.

[0040] The above scheme adopts the coordinated work of the acquisition module 11, the response module 12, the extraction module 13 and the adjustment module 14. The electrical characteristics of the circuit to be tested can be automatically acquired through the acquisition module 11, and the response module 12 quickly searches for the test signal matching the electrical characteristics of the circuit to be tested in the preset database, and injects the test signal into the circuit to be tested. The test signal of the circuit to be tested is monitored in real time, and the electrical characterization value of the test signal is extracted by the extraction module 13, and the corresponding adjustment parameter is matched according to the electrical characterization value. The test signal is accurately adjusted to improve the accuracy of the test. When there is no test signal matching the electrical characteristics of the circuit to be tested in the preset database, a database object is automatically created for the electrical characteristics, and the actual test signal is added to the database object. Specifically, by reading the test signal and the test signal from the test process corresponding to the electrical characteristics, storing them in the database object, data support is provided for subsequent tests. Further, in order to ensure the safety of the test, the extraction module 13 is also used to compare the electrical characterization value with the preset safety threshold range. When the electrical characterization value exceeds the safety threshold range, the adjustment module 14 adjusts the test signal in time to prevent equipment damage or safety accidents.

[0041] See also Figure 2 , Figure 2 1 is a flow chart of an embodiment of a method for accurately detecting the grounding loop resistance of a high-voltage cable of the present application. In this embodiment, the method comprises the following steps:

[0042] Step S21: Acquire the electrical characteristics of the circuit to be tested.

[0043] In some embodiments, obtaining the electrical characteristics of the circuit to be tested includes: matching corresponding specification information from a preset information summary table according to the identity information of the circuit to be tested, and obtaining current data and voltage data of the current circuit to be tested.

[0044] Specifically, the identity information of the circuit to be tested may include the number or location identification of the circuit to be tested. For example, the identity information of the circuit to be tested may be obtained by reading the identity sensing area or identity identification plate of the circuit to be tested through a sensor or a scanning device. The information summary table may be a pre-established database or table, and the information summary table at least includes the identity information of each circuit and its corresponding specification information. The specification information may include the resistance range, current carrying capacity, voltage level, etc. of the circuit. To obtain the current data and voltage data of the current circuit to be tested, the current and voltage of the circuit to be tested may be measured by a current sensor and a voltage sensor respectively, or the current current data and voltage data of the circuit to be tested may be called from the terminal control system.

[0045] Step S22: In response to the electrical characteristic currently having a matching test signal in the preset database, inject the test signal into the circuit to be tested, and monitor the test signal of the circuit to be tested in real time.

[0046] In some embodiments, the method further includes: matching a first path node corresponding to specification information in a preset database based on specification information in the electrical characteristics, and matching a corresponding test signal under the first path node using current current data and voltage data of the circuit to be tested.

[0047] Specifically, the first path node corresponding to the specification information can be located in the database preset by the specification information. The first path node represents the entry point of all data related to the specification information in the database. The current current data and voltage data of the circuit to be tested are used to further search for matching test signals under the first path node to find the test signal that best matches the current state of the circuit to be tested. Based on the electrical characteristics of the circuit to be tested, the most suitable test signal is efficiently matched in the preset database, which improves the accuracy and efficiency of the loop resistance test and reduces the cost and risk of manual intervention.

[0048] In some embodiments, the method further includes: in response to the electrical feature not currently having a matching corresponding test signal in the preset database, creating a database object for the electrical feature; and adding the actual test signal of the electrical feature to the database object of the electrical feature. Adding the test signal and its related data obtained during the actual test process to the newly created database object can continuously expand and improve the database, thereby improving the adaptability and accuracy of the system.

[0049] In some specific embodiments, adding the actual test signal of the electrical characteristic to the database object of the electrical characteristic includes: reading the test signal and the test signal corresponding to each test signal from the test process of at least one circuit to be tested corresponding to the electrical characteristic; and storing the read test signal and the test signal corresponding to each test signal in the database object of the electrical characteristic.

[0050] In addition, considering that there may be failures during the test process, in some specific embodiments, the test data added to the new database object is screened, the test data with successful test results is screened, and the screened test data is added to the preset database for subsequent testing. This ensures that the data in the preset database are all verified valid data, thereby improving the accuracy and efficiency of the test.

[0051] Step S23: extract at least one electrical characterization value of the test signal, and match a corresponding adjustment parameter according to the electrical characterization value.

[0052] Specifically, the electrical characterization value may include voltage value, current value, resistance value, etc. The resistance of the high-voltage cable grounding loop may be obtained by directly extracting the resistance value or by calculating the voltage value and the current value. The safety threshold range of the electrical characterization value may be determined based on factors such as equipment specifications, safety standards, and past experience.

[0053] In some specific embodiments, extracting at least one electrical characterization value of the test signal, and matching the corresponding adjustment parameter according to the electrical characterization value further includes: comparing each electrical characterization value with a preset corresponding electrical characterization value safety threshold range.

[0054] Step S24: adjusting the test signal according to the adjustment parameter.

[0055] In some application scenarios, the electrical characterization value includes a maximum voltage value, and the safety threshold range of the electrical characterization value includes a voltage safety threshold range; in response to the maximum voltage value being higher than the voltage safety threshold range, the voltage value of the test signal is reduced.

[0056] Specifically, in the real-time monitored test signal, the highest voltage value can be continuously monitored and recorded, and the recorded highest voltage value can be compared with the preset voltage safety threshold range. If the highest voltage value is higher than the upper limit of the voltage safety threshold range, the voltage value of the test signal is reduced to prevent equipment damage or safety accidents. The adjusted test signal is re-injected into the circuit to be tested, and the test signal is continuously monitored to verify the adjustment effect.

[0057] In some application scenarios, the electrical characterization value includes a minimum voltage value, and the safety threshold range of the electrical characterization value includes a voltage safety threshold range; in response to the minimum voltage value being lower than the voltage safety threshold range, the voltage value of the test signal is increased.

[0058] Specifically, in the test signal monitored in real time, the lowest voltage value can be paid attention to and recorded at the same time, and the recorded lowest voltage value can be compared with the preset voltage safety threshold range. If the lowest voltage value is lower than the lower limit of the voltage safety threshold range, the voltage value of the test signal is increased to ensure the effectiveness and accuracy of the test, and the adjusted test signal is re-injected into the circuit to be tested, and the test signal is continuously monitored.

[0059] The above scheme automatically obtains the electrical characteristics of the circuit to be tested, quickly searches for the test signal that matches the electrical characteristics of the circuit to be tested in the preset database, and injects the test signal into the circuit to be tested. At the same time, the test signal of the circuit to be tested is monitored in real time, the electrical characterization value of the test signal is extracted, and the corresponding adjustment parameters are matched according to these values ​​to accurately adjust the test signal to improve the accuracy of the test. When there is no test signal matching the electrical characteristics of the circuit to be tested in the preset database, a database object is automatically created for the electrical characteristics, and the actual test signal is added to the object, the database is continuously improved, the adaptability of the system is improved, and data support is provided for subsequent tests. In order to ensure the safety of the test, the electrical characterization value is further compared with the preset safety threshold range. When the electrical characterization value exceeds the safety threshold range, the test signal is adjusted in time to prevent equipment damage or safety accidents.
