[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0026] Embodiment 1

[0027] Figure 1 This is a flow chart of a pole tower detection method provided in the first embodiment of the present invention. This embodiment can be applied to the case of detecting a pole tower, and is particularly applicable to the case of detecting the grounding resistance state of the pole tower based on the lightning current information on the pole tower and the ground current information of the pole tower. The method can be executed by the pole tower detection device provided in the embodiment of the present invention, and the device can be implemented in software and / or hardware. The device can be configured in an electronic device that carries the pole tower detection function. The method specifically includes:

[0028] S110: Using a first monitoring device installed on the lightning protection equipment of the target tower, first lightning current information on the target tower is obtained.

[0029] Among them, the pole tower is one of the basic equipment in the overhead distribution line, which refers to a pole-shaped or tower-shaped structure used to support the overhead transmission line conductors and the overhead ground wires and keep a certain distance between them and the ground. The lightning protection device can be a lightning conductor. The target pole tower is a pole tower that needs to be installed with a first monitoring device to obtain the first lightning current information. The first monitoring device is installed on the lightning protection device of the target pole tower, and is used to monitor the lightning current information when lightning strikes the top of the target pole tower or the lightning protection device and the lightning protection device does not flash over. The first lightning current information refers to the relevant information of the lightning current obtained by the first monitoring device when lightning strikes the top of the target pole tower or the lightning protection device and the lightning protection device does not flash over. The first lightning current information includes the lightning current waveform flowing through the lightning protection device of the target pole tower, the lightning current value, and the time it takes for the lightning current to reach the target pole tower from the lightning strike position.

[0030] It should be noted that, under normal circumstances when the lightning arrester of the pole tower or the top of the pole tower is not struck by lightning, almost no current flows through the lightning arrester on the pole tower and the grounding down conductor of the pole tower. Only when the lightning arrester of the pole tower or the top of the pole tower is struck by lightning, causing the lightning arrester to strike back or the insulator to flash over, will a large current flow through the lightning arrester on the pole tower and the grounding down conductor of the pole tower. The grounding down conductor is a metal conductor that connects electrical equipment to the grounding body, such as a lightning protection grounding lead wire. The strike back of the lightning arrester refers to the situation where lightning strikes the lightning arrester, and the flashover of the insulator refers to the situation where the insulator is broken down and loses its insulating function when lightning strikes the top of the pole tower.

[0031] Specifically, a first monitoring device is installed on the lightning protection device on either side of the target tower, and the first monitoring device is used to collect and obtain current information on the lightning protection device of the target tower, and the obtained current information on the lightning protection device is sent to the tower detection system as the first lightning current information.

[0032] S120: Using a second monitoring device installed on the grounding equipment of the target tower, obtain the ground current information of the target tower.

[0033] Among them, the grounding equipment refers to the general term for the grounding electrode buried underground and the connecting wire from the grounding electrode to the equipment. The component structure of the grounding equipment includes inductance, resistance and grounding down conductor. The second monitoring device refers to a current monitoring device installed on the grounding equipment of the target tower, which is used to monitor the grounding current information on the grounding down conductor of the target tower. The grounding current information refers to the relevant information of the current flowing through the grounding down conductor obtained by the second monitoring device when lightning strikes the top of the target tower or the lightning protection device and the lightning protection device does not flash over. The grounding current information includes the grounding current waveform and grounding current value flowing through the grounding down conductor of the target tower.

[0034] Specifically, a second monitoring device is installed on the grounding equipment of the target tower, and the second monitoring device is used to collect and obtain current information on the grounding down conductor of the target tower, and the current information obtained on the grounding down conductor is sent to the tower detection system as the ground current information.

[0035] S130: Determine a tower shunt coefficient of a target tower according to the first lightning current information and the ground current information.

[0036] The tower shunt coefficient is the ratio of the ground current value to the lightning current value. The tower shunt coefficient can be used as an indicator to measure the performance of the tower grounding equipment. In this embodiment, the larger the tower shunt coefficient, the better the performance of the tower grounding equipment.

[0037] Specifically, after the tower detection system obtains the first lightning current information and the ground current information of the target tower, the tower shunt coefficient of the target tower is calculated according to the first lightning current information and the ground current information. The tower shunt coefficient of the target tower is calculated as shown in formula (1):

[0038] β=I d / I T (1)

[0039] Among them, β is the tower diversion coefficient, I d is the ground current value, I T Preferably, the ground current amplitude can be determined according to the ground current waveform and the ground current value, and the ground current amplitude is used as I d ; Determine the lightning current amplitude according to the lightning current waveform and lightning current value, and use the lightning current amplitude as I T .

[0040] S140. Determine the grounding resistance state of the target tower according to the tower shunt coefficient.

[0041] It should be noted that the grounding equipment of the tower includes inductance and resistance, and the resistance on the grounding equipment can be used as the grounding resistance. After the tower is built, the inductance on the grounding equipment of the tower will not change during subsequent use, so the grounding resistance on the grounding equipment is the main factor affecting the shunt coefficient of the tower.

[0042] Specifically, the comparison parameter of the tower shunt coefficient can be pre-set according to the actual working condition of the tower, and two comparison parameters can be pre-set, and the values ​​of the two comparison parameters are different. After the tower detection system determines the tower shunt coefficient of the target tower, it compares the tower shunt coefficient with the two pre-set comparison parameters, and determines the grounding resistance state of the target tower according to the comparison result.

[0043] Exemplarily, the grounding resistance state is divided into a good state, a qualified state and an abnormal state. The two comparison parameters can be represented by P1 and P2 respectively, and P1>P2; the tower shunt coefficient of the target tower is represented by β. If β>P1, the grounding resistance state of the target tower is determined to be a good state; if P1>β>P2, the grounding resistance state of the target tower is determined to be a qualified state; if β>P2, the grounding resistance state of the target tower is determined to be a dangerous state.

[0044] Preferably, after determining the pole tower shunt coefficient of the target pole tower, the pole tower detection system can also generate an evaluation report of the target pole tower according to the pole tower shunt coefficient and the grounding resistance state of the target pole tower, and send the evaluation report to the user, so that the user can re-lay the grounding equipment of the target pole tower when the grounding resistance state of the target pole tower is abnormal. The evaluation report refers to a document recording the test results of the target pole tower.

[0045] Specifically, after the pole tower detection system determines the grounding resistance state of the target pole tower according to the pole tower shunt coefficient of the target pole tower, the pole tower shunt coefficient and grounding resistance state of the target pole tower are recorded in the evaluation report in the form of text, and the evaluation report is displayed on the display screen of the pole tower detection system. If the user determines that the grounding resistance state of the target pole tower is in a good state according to the evaluation report, no further action will be taken for the target pole tower; if the user determines that the grounding resistance state of the target pole tower is in a qualified state according to the evaluation report, the user can focus on the observation of the target pole tower, so as to timely re-lay the grounding equipment of the target pole tower when the grounding resistance state of the target pole tower changes to a non-dangerous state; if the user determines that the grounding resistance state of the target pole tower is in a dangerous state according to the evaluation report, the grounding equipment of the target pole tower will be re-laid.

[0046] The technical solution provided in this embodiment uses a first monitoring device installed on the lightning protection device of the target tower to obtain the first lightning current information on the target tower; uses a second monitoring device installed on the grounding device of the target tower to obtain the ground current information of the target tower; determines the tower shunt coefficient of the target tower according to the first lightning current information and the ground current information; and determines the grounding resistance state of the target tower according to the tower shunt coefficient. The above technical solution solves the problem of large manual workload, difficult on-site operation and low detection efficiency when performing tower detection by potential drop method, three-pole method, high-frequency parallel method or clamp meter method, and solves the problem that when the tower is detected by the existing tower detection scheme, the influence of the surrounding environment and soil properties of the tower on the tower detection results is not considered, resulting in inaccurate tower detection results. The online detection of the tower is realized, the human participation process in the tower detection process is reduced, the labor cost is reduced, and the tower detection efficiency is improved. At the same time, the detection results obtained by the above tower detection method are not affected by the environment and soil properties around the target tower, and the accuracy of the tower detection results is improved.

[0047] Embodiment 2

[0048] Figure 2 A flowchart of a pole tower detection method provided in the second embodiment of the present invention is provided. This embodiment is optimized on the basis of the above embodiment, and provides a preferred embodiment of determining the lightning strike interval according to the first lightning current information and the second lightning current information of the neighboring pole tower, and then determining the positional relationship between the lightning strike position and the first monitoring device according to the lightning strike interval, and determining the pole tower shunt coefficient based on the positional relationship according to the lightning current information and the ground current information. Specifically, as Figure 2 As shown, the tower detection method provided in this embodiment may include:

[0049] S210: Use a first monitoring device installed on the lightning protection equipment of the target tower to obtain first lightning current information on the target tower.

[0050] S220: Use a second monitoring device installed on the grounding device of the target tower to obtain the ground current information of the target tower.

[0051] S230: Determine neighboring poles of the target pole.

[0052] It should be noted that in actual use scenarios of pole towers, multiple pole towers are often used to jointly support overhead transmission line conductors and overhead ground wires.

[0053] The neighboring towers are towers adjacent to the target tower.

[0054] Specifically, the position information of all poles is stored in the pole detection system in advance. After the target pole is determined, the pole detection system determines the neighboring poles of the target pole according to the pre-stored position information of the pole. The neighboring pole of the target pole may be a pole located at an adjacent position in any direction of the target pole, for example, a neighboring pole may be a pole located at an adjacent position in front of the target pole.

[0055] S240: Determine a lightning strike interval according to the first lightning current information and the second lightning current information of the neighboring tower.

[0056] Among them, when lightning strikes the lightning protection device of the target tower, a lightning current will be formed on the wire between the target tower and the neighboring tower, and the lightning current can be transmitted to the lightning protection device of the neighboring tower through the wire. The relevant information of the lightning current monitored by the third monitoring device installed on the lightning protection device of the neighboring tower is used as the second lightning current information. The third monitoring device is installed on the lightning protection device of the neighboring tower and is used to monitor the lightning current information. The lightning strike interval refers to the area where the lightning strikes when the lightning strikes the lightning protection device of the target tower. The lightning strike interval can be any area around the target tower.

[0057] Specifically, the lightning strike interval may be determined according to the lightning current direction in the first lightning current information and the lightning current direction in the second lightning current information of the neighboring tower.

[0058] The lightning current direction in the first lightning current information refers to the direction of the lightning current monitored by the first monitoring device installed on the lightning protection device of the target tower. The lightning current direction in the second lightning current information refers to the direction of the lightning current monitored by the third monitoring device installed on the lightning protection device of the neighboring tower.

[0059] Specifically, after the pole tower detection system obtains the first lightning current information through the first monitoring device, it determines the lightning current waveform flowing through the target pole tower lightning arrester according to the first lightning current information, and determines the lightning current direction in the first lightning current information according to the lightning current waveform flowing through the target pole tower lightning arrester. After the pole tower detection system obtains the second lightning current information, it determines the lightning current waveform flowing through the neighboring pole tower lightning arrester according to the second lightning current information, and determines the lightning current direction in the second lightning current information according to the lightning current waveform flowing through the neighboring pole tower lightning arrester. According to the lightning current direction in the first lightning current information and the lightning current direction in the second lightning current information of the neighboring pole tower, it is determined whether the lightning strike interval is located in the area between the target pole tower and the neighboring pole tower.

[0060] Exemplarily, this step may also divide the interval near the target tower into a first interval and a second interval, and then determine whether the lightning strike interval is located in the first interval or in the second interval according to the lightning current direction in the first lightning current information and the lightning current direction in the second lightning current information. Specifically, this may be achieved through the following sub-steps:

[0061] S2401: A conductor section connecting a target pole tower and a neighboring pole tower is taken as a first section, and other sections except the first section are taken as second sections.

[0062] The conductor section refers to the area where the conductors connecting the target tower and the neighboring towers are located.

[0063] Specifically, according to actual needs, a target pole area is set with the target pole as the center, and the target pole area refers to the area where the lightning protection device of the target pole may be struck by lightning. The interval on the wire connecting the target pole and the neighboring pole is taken as the first interval, and the other intervals in the target pole area except the first interval are taken as the second interval.

[0064] S2402: If the direction of the lightning current in the first lightning current information is the same as the direction of the lightning current in the second lightning current information of the neighboring tower, then the lightning strike interval is the first interval.

[0065] Specifically, if the tower detection system determines that the lightning current direction in the first lightning current information is the same as the lightning current direction in the second lightning current information of the neighboring tower, it is determined that the lightning strike position is located on the wire between the target tower and the neighboring tower, so the lightning strike interval is the first interval.

[0066] S2403: If the direction of the lightning current in the first lightning current information is opposite to the direction of the lightning current in the second lightning current information, then the lightning strike interval is the second interval.

[0067] Specifically, if the tower detection system determines that the direction of the lightning current in the first lightning current information is opposite to the direction of the lightning current in the second lightning current information, it is determined that the lightning strike position is not on the wire between the target tower and the neighboring tower, so the lightning strike interval is the second interval.

[0068] Exemplarily, if the lightning strike interval is the first interval, the lightning strike position may also be located, wherein the lightning strike position refers to the position where the lightning strikes.

[0069] Specifically, if the lightning strike interval is the first interval, the distance between the lightning strike position and the target tower can be calculated according to the double-terminal traveling wave ranging method. The double-terminal traveling wave ranging method is a ranging method implemented according to the traveling wave theory. The calculation formula for the distance between the lightning strike position and the target tower is as shown in formula (2):

[0070] L′=[L+(t1-t2)×V] / 2 (2)

[0071] Wherein, L′ is the distance between the lightning strike position and the target tower; L is the distance between the target tower and the neighboring tower, and the distance between the target tower and the neighboring tower can be pre-stored in the tower detection system; t1 is the time for the lightning current to reach the target tower from the lightning strike position; t2 is the time for the lightning current to reach the neighboring tower from the lightning strike position; V is the wave velocity of the lightning current, and 0.9 times the speed of light can be used as the wave velocity of the lightning current.

[0072] By determining the lightning strike interval according to the lightning current direction in the first lightning current information and the lightning current direction in the second lightning current information, the location where the lightning strike occurs can be located, so as to facilitate subsequent on-site survey of the location where the lightning strike occurs by maintenance personnel.

[0073] S250: Determine the positional relationship between the lightning strike position and the first monitoring device according to the lightning strike interval.

[0074] Among them, the positional relationship between the lightning strike position and the first monitoring device can be a same-side positional relationship or a different-side positional relationship. The same-side positional relationship means that the lightning strike position and the first monitoring device are on the same side of the target tower, and the different-side positional relationship means that the lightning strike position and the first monitoring device are respectively located on both sides of the target tower. For example, if the lightning strike position and the first monitoring device are both on the left side of the target tower, the positional relationship between the lightning strike position and the first monitoring device is a same-side positional relationship; if the lightning strike position is located on the left side of the target tower, and the first monitoring device is located on the right side of the target tower, the positional relationship between the lightning strike position and the first monitoring device is a different-side positional relationship.

[0075] Specifically, the interval where the first monitoring device is located is stored in the pole tower detection system in advance. After the pole tower detection system determines the lightning strike interval, the lightning strike interval is compared with the interval where the first monitoring device is located. If the lightning strike interval is consistent with the interval where the first monitoring device is located, the positional relationship between the lightning strike position and the first monitoring device is a same-side positional relationship; if the lightning strike interval is inconsistent with the interval where the first monitoring device is located, the positional relationship between the lightning strike position and the first monitoring device is a different-side positional relationship.

[0076] S260: Based on the position relationship, determine the tower shunt coefficient according to the first lightning current information and the ground current information.

[0077] It should be noted that when the positional relationship between the lightning strike position and the first monitoring device is a same-side positional relationship or a different-side positional relationship, the specific calculation method of the tower shunt coefficient is also different.

[0078] Exemplarily, this embodiment can determine the calculation method of the tower shunt coefficient according to the positional relationship between the lightning strike position and the first monitoring device, and then calculate the tower shunt coefficient of the target tower according to the determined calculation method. Specifically, it can be achieved through the following sub-steps:

[0079] S2601. If the position relationship is that the lightning strike position and the first monitoring device are located on the same side of the target tower, the ratio between the ground current amplitude in the ground current information and the lightning current amplitude in the first lightning current information is used as the tower shunt coefficient.

[0080] The ground current amplitude is the maximum value of the ground current monitored by the second monitoring device; and the lightning current amplitude in the first lightning current information is the maximum value of the lightning current monitored by the first monitoring device.

[0081] Specifically, if the tower detection system determines that the positional relationship between the lightning strike position and the first monitoring device is a same-side positional relationship, then the lightning strike position and the first monitoring device are located on the same side of the target tower. At this time, the amplitude of the lightning current in the first lightning current information is the amplitude of the lightning current flowing through the target tower. In this case, the calculation formula of the tower shunt coefficient of the target tower is as shown in formula (3):

[0082] β=I2 / I1 (3)

[0083] Among them, β is the tower shunt coefficient of the target tower; I2 is the amplitude of the ground current; I1 is the amplitude of the lightning current flowing through the target tower.

[0084] S2602. If the position relationship is that the lightning strike position and the first monitoring device are located on opposite sides of the target tower, the ratio of the ground current amplitude to the sum of the ground current amplitude and the lightning current amplitude is used as the tower shunt coefficient.

[0085] Specifically, if the tower detection system determines that the positional relationship between the lightning strike position and the first monitoring device is a different-side positional relationship, then the lightning strike position and the first monitoring device are located on different sides of the target tower. At this time, the sum of the ground current amplitude and the lightning current amplitude is the lightning current amplitude flowing through the target tower. In this case, the calculation formula of the tower shunt coefficient of the target tower is as shown in formula (4):

[0086] β=I2 / (I1+I2) (4)

[0087] Among them, β is the tower shunt coefficient of the target tower; I2 is the amplitude of the ground current; I1 is the amplitude of the lightning current flowing through the target tower.

[0088] The calculation method of the tower shunt coefficient is determined according to the positional relationship between the lightning strike position and the first monitoring device, and the tower shunt coefficient of the target tower is calculated according to the determined calculation method, thereby improving the accuracy of the calculation result of the tower shunt coefficient.

[0089] S270. Determine the grounding resistance state of the target tower according to the tower shunt coefficient.

[0090] The technical solution of this embodiment first determines the neighboring pole towers of the target pole tower; determines the lightning strike interval according to the first lightning current information and the second lightning current information of the neighboring pole tower; determines the positional relationship between the lightning strike position and the first monitoring device according to the lightning strike interval; and determines the pole tower shunt coefficient based on the positional relationship according to the first lightning current information and the ground current information. The above solution provides an optimal real-time method for determining the positional relationship between the lightning strike position and the first monitoring device according to the lightning strike interval, and then determining the pole tower shunt coefficient based on the positional relationship, which can improve the accuracy of the calculation result of the pole tower shunt coefficient, thereby further improving the accuracy of the ground resistance state detection of the target pole tower.

[0091] Embodiment 3

[0092] Figure 3 This is a flowchart of a pole tower detection method provided in the third embodiment of the present invention. This embodiment is optimized on the basis of the above embodiments, and provides a preferred embodiment in which when the lightning current value flowing through the lightning protection device is greater than the preset lightning current threshold, the first monitoring device is used to obtain the first current information of the target pole tower; when the ground current value flowing through the grounding device is greater than the ground current threshold, the second monitoring device is used to obtain the ground current information of the target pole tower. Specifically, Figure 3 As shown, the tower detection method provided in this embodiment may include:

[0093] S310: Determine whether the lightning current value flowing through the lightning protection device is greater than a preset lightning current threshold.

[0094] The lightning current threshold can be preset according to actual conditions.

[0095] Specifically, the pole tower detection system monitors the lightning current value flowing through the lightning arrester in real time through the first monitoring device, and compares the lightning current value monitored by the first monitoring device with the preset lightning current threshold value to determine in real time whether the lightning current value flowing through the lightning arrester is greater than the preset lightning current threshold value. If the lightning current value is less than the preset lightning current threshold value, the lightning current value flowing through the lightning arrester continues to be monitored in real time through the first monitoring device, and the first lightning current information other than the lightning current value on the target pole tower lightning arrester is no longer obtained.

[0096] S320: If yes, use a first monitoring device installed on the lightning protection device of the target tower to obtain first lightning current information on the target tower.

[0097] Specifically, if the tower detection system determines that the lightning current value is greater than the lightning current threshold value according to the monitoring result of the first monitoring device, the first monitoring device installed on the lightning protection device of the target tower is used to further obtain the first lightning current information of the lightning protection device of the target tower.

[0098] S330: Determine whether the value of the ground current flowing through the grounding device is greater than the ground current threshold.

[0099] The ground current threshold can be preset according to actual conditions.

[0100] Specifically, the pole tower detection system monitors the value of the ground current flowing through the grounding device in real time through the second monitoring device, and compares the value of the ground current monitored by the second monitoring device with the preset ground current threshold value to determine in real time whether the value of the ground current flowing through the grounding device is greater than the preset ground current threshold value. If the ground current value is less than the preset ground current threshold value, the second monitoring device continues to monitor the value of the ground current flowing through the grounding device in real time, and no longer continues to obtain the ground current information other than the ground current value on the target pole tower grounding device.

[0101] S340: If yes, use a second monitoring device installed on the grounding device of the target tower to obtain the ground current information of the target tower.

[0102] Specifically, if the tower detection system determines that the ground current value is greater than the ground current threshold according to the monitoring result of the second monitoring device, the second monitoring device installed on the grounding device of the target tower is used to further obtain the ground current information on the grounding device of the target tower.

[0103] S350: Determine a tower shunt coefficient of a target tower according to the first lightning current information and the ground current information.

[0104] S360. Determine the grounding resistance state of the target tower according to the tower shunt coefficient.

[0105] The technical solution of this embodiment first determines whether the lightning current value flowing through the lightning protection device is greater than the preset lightning current threshold; if so, the first monitoring device installed on the lightning protection device of the target tower is used to obtain the first lightning current information on the target tower; then determines whether the ground current value flowing through the grounding device is greater than the ground current threshold; if so, the second monitoring device installed on the grounding device of the target tower is used to obtain the ground current information of the target tower. The above technical solution solves the problem of resource waste caused by using the first monitoring device and the second monitoring device to obtain the first lightning current information and the ground current information in real time. By presetting the lightning current threshold and the ground current threshold, it is ensured that the first monitoring device will only collect the complete first lightning current information when the lightning current value is greater than the lightning current threshold, and transmit the first lightning current information to the tower detection system; the second monitoring device will only collect the complete ground current information when the ground current value is greater than the ground current threshold, and transmit the ground current information to the tower detection system, saving information transmission resources.

[0118] Furthermore, the lightning strike interval determination unit includes:

[0119] The current direction comparison subunit is used to determine the lightning strike interval according to the lightning current direction in the first lightning current information and the lightning current direction in the second lightning current information of the neighboring tower.

[0120] Exemplarily, the current direction comparison subunit is specifically used for:

[0121] The conductor section connecting the target pole tower and the neighboring pole tower is regarded as the first section, and the other sections except the first section are regarded as the second section;

[0122] If the direction of the lightning current in the first lightning current information is the same as the direction of the lightning current in the second lightning current information of the neighboring tower, the lightning strike interval is the first interval;

[0123] If the direction of the lightning current in the first lightning current information is opposite to the direction of the lightning current in the second lightning current information, the lightning strike interval is the second interval.

[0124] Exemplarily, the tower flow splitting coefficient calculation unit is specifically used for

[0125] If the position relationship is that the lightning strike position and the first monitoring device are located on the same side of the target tower, the ratio between the ground current amplitude in the ground current information and the lightning current amplitude in the first lightning current information is used as the tower shunt coefficient;

[0126] If the position relationship is that the lightning strike position and the first monitoring device are located on opposite sides of the target tower, the ratio of the ground current amplitude to the sum of the ground current amplitude and the lightning current amplitude is used as the tower shunt coefficient.
