As described in the background section, with the rapid development of electric power systems, it is required to transmit electric power across an extra-high voltage transmission line, and the distance of which is relatively long. In order to reduce land occupation, the special-environment ultra-high voltage transmission line often needs to pass through complex terrains and special-environment areas, so that the installation environment of the ultra-high voltage transmission line is bad. The insulator string is used for supporting and fixing a circuit or equipment related to the circuit in the power system and plays a role in isolating current, but the insulator string is exposed in the air for a long time and is affected by continuous leakage current, lightning flashover, salt corrosion, external damage and the like, and the insulator string can fail. The failure of the insulator string can affect the stable operation of the power system, and for example, the failure of the insulator string can cause the energy loss of the power system to increase, cause the abnormal temperature rise of the connection point of the insulator string, and reduce the power transmission efficiency of the system; secondly, the failure of the insulator string can lead to the decrease of the insulating property of the insulator string, thereby aggravating the aging and failure rate of the equipment; finally, if the insulator string is broken down due to the failure of the insulator string, serious accidents such as short circuit, power failure and the like of the power transmission line can be caused, and the safety and stability of the power system are threatened. Therefore, fault detection of the insulator string is necessary.
In the prior art, faults of insulator strings are detected mainly in two ways, one is: whether the insulator is damaged or not is observed in a long distance by using a telescope and an ultrasonic tester manually, however, the insulator is affected by subjective factors of a person in a manual observation mode, and therefore fault detection of the insulator string is not always accurate. The other is: by installing the sensing equipment, whether the insulator string fails or not is determined by only monitoring whether the insulation performance and the pollution degree of the insulator meet the requirements, but the comprehensive utilization rate of the existing data is low, so that the accuracy of failure judgment of the insulator string is low.
In view of this, an embodiment of the present application proposes a fault detection method for an insulator string in a power transmission line, which is applied to a data fusion end, and referring to fig. 1, the method includes the following steps:
step 101, obtaining leakage current corresponding to an insulator string in a preset power transmission line, and detecting electric leakage of the insulator string based on the leakage current.
In this step, the insulator string is a device used for supporting and fixing a line or related to the line in the power system, and has an important influence on the normal operation of the transformer substation and the transmission line. Therefore, fault detection of the insulator string is necessary. Because the surface of the insulator string is covered by dirt, salted and corroded or has too high humidity, a conductive path is formed on the surface of the insulator string, so that current, namely leakage current, is generated on or in the surface of the insulator string. By way of example, a drainage ring is installed at the top of the insulator string of the power transmission line, and then current in the drainage ring is measured, so that the purpose of monitoring leakage current on the surface of the insulator string in real time is achieved. Therefore, the degree of the environmental influence to which the insulator string is subjected can be determined by the magnitude of the leakage current to the insulator string, and when the leakage current of the insulator string is relatively large, the degree of the environmental influence to which the insulator string is subjected is relatively large; in the case where the leakage current of the insulator string is relatively small, it is indicated that the insulator string is subjected to a relatively small degree of environmental impact. Therefore, it is necessary to detect the leakage current of the insulator string to accurately determine the degree of environmental impact to which the insulator string is subjected.
It should be noted that, can detect the leakage current of insulator chain through leakage current detection module, leakage current detection module adopts dynamic power management strategy to satisfy equipment low-power consumption requirement, and the shell adopts waterproof metal material, satisfies industrial grade product requirement, is applicable to various abominable climatic environment. In addition, the leakage current detection module is convenient to install, and after the leakage current detection module is put into operation, the pollution state and the development trend of the insulator can be mastered in time, so that the pollution flashover accident of the circuit can be effectively prevented, and the safe operation and the intelligent level of the circuit can be improved.
Step 102, in response to determining that the insulator string has electric leakage, acquiring a first image corresponding to the insulator string, and performing damage identification on the insulator string in the first image.
In this step, the magnitude of the leakage current of the insulator string is related to the environmental factor of the insulator string, and the factors such as the change of the environmental humidity where the insulator string is located, excessive dirt on the surface of the insulator string, icing of the insulator string, zero-value insulator string and the like cause the increase of the leakage current of the insulator, so that the insulator string is in a leakage phenomenon. It should be noted that, the occurrence of the electric leakage of the insulator string indicates that the insulator string is relatively greatly affected by environmental factors but does not cause a failure, or the insulator string has failed, and therefore, the occurrence of the electric leakage through the insulator string cannot necessarily determine that the insulator string has failed. And the first image of the insulator string is required to be damaged and identified, so that the accuracy of judging the occurrence of faults of the insulator string is improved. The damage identification is performed on the appearance of the insulator string through binocular infrared monitoring, and the binocular infrared monitoring adopts a solar energy and/or lithium battery power supply mode, wherein the power supply voltage of the lithium battery can be 12 volts.
The present application may also identify the breakage of the internal image of the insulator string, and also indicate the breakage of the insulator string when the breakage occurs in the insulator string. Whether the insulator string is damaged or not can be judged based on the internal image and the first image of the insulator, and the accuracy of judging that the insulator string fails is further improved. Illustratively, the damage identification is performed to the inside of the insulator string by the millimeter wave radar. The millimeter wave radar has the advantages of strong environmental adaptability, low power consumption, strong penetrating power and the like, and can realize all-weather monitoring on the state of the insulator string.
Step 103, in response to determining that the insulator string in the first image is damaged, obtaining first detection data corresponding to the insulator string, and overlapping the first detection data on the first image to obtain a first detection image.
In this step, in the case where the insulator string in the first image is broken, it is indicated that the insulator string may malfunction. It should be noted that, only under the conditions of leakage current of the insulator string and damage of the insulator string in the first image, the insulator string can be described as having a high probability of failure, and subsequent ineffective early warning of the failure of the insulator string is greatly reduced. In order to enable the follow-up fault detection of the insulator string to be more accurate, first detection data corresponding to the insulator string are required to be obtained, wherein the first detection data at least comprise temperature data, the first detection data can be acquired through multiple sensors, and the purpose of data linkage of the multiple sensors is achieved. And overlapping the first detection data on the first image to obtain a first detection image, so that whether the insulator string has faults or not can be comprehensively reflected by the first detection image.
And 104, transmitting the first detection image to a data processing terminal so as to determine a first fault of the insulator string in the first detection image through the data processing terminal.
In this step, the data fusion end has an application range, and only the first detection image of the insulator string in the application range can be determined, so that a plurality of data fusion ends in the application are connected with the data processing terminal, wherein the data fusion ends adopt a power supply mode of solar energy and/or lithium batteries, for example, the power supply voltage of the lithium batteries can be 12 volts. And sending the first detection image to a data processing terminal, and determining whether the insulator string in the first detection image has faults or not by using the data processing terminal. And in the case that the insulator string fails, determining the failure as a first failure, wherein the first failure is at least one type of failure in all failure types of the insulator string. According to the method and the device, the first detection image determined by the data fusion end is used for sharing the processing pressure of the data processing terminal, so that the efficiency of determining the faults of the insulator string is improved. In addition, whether the insulator string has a fault or not can be comprehensively reflected by the first detection image, and therefore accuracy of determining the fault of the insulator string through the first detection image is finally improved.
Through the scheme, the leakage current corresponding to the insulator string in the preset power transmission line is obtained, and the leakage detection is performed on the insulator string based on the leakage current so as to accurately determine the environmental influence degree of the insulator string. In response to determining that the insulator string is leaked, a first image corresponding to the insulator string is acquired, and damage identification is performed on the insulator string in the first image, so that the accuracy of judging that the insulator string is failed is improved. In response to determining that the insulator string in the first image is damaged, first detection data corresponding to the insulator string are obtained, and the first detection data are superimposed on the first image to obtain a first detection image, so that whether the insulator string has faults or not can be comprehensively reflected by the first detection image. And sending the first detection image to a data processing terminal so as to determine a first fault of the insulator string in the first detection image through the data processing terminal.
In some embodiments, before sending the first detection image to a data processing terminal, the method comprises: and compressing the first detection image.
In this embodiment, the first detection image needs to be sent to the data processing terminal through the data fusion end, and under the condition that the data size of the first detection image is relatively large, there are many problems such as high transmission power consumption, heavy network load, poor real-time performance, and the like, and the first detection image is limited by the problems of 4G communication flow and cost. Therefore, before the first detection image is sent to the data processing terminal, the first detection image needs to be compressed, so that the data size of the first detection image is reduced, and the purpose of improving the data transmission efficiency between the data fusion terminal and the data processing terminal is achieved.
In some embodiments, the compressing the first detection image includes: detecting a background area of the first detection image to determine the background area of the first detection image and the area of the background area; and in response to determining that the area is larger than a preset area, compressing the background area in the first detection image.
In this embodiment, if the first detection image is subjected to indiscriminate compression without dividing the first detection image into regions so as to reduce the data amount of the first detection image, the image quality of the first detection image is damaged, so that the data processing terminal cannot identify the first detection image. In order to solve the above-described problem, the present embodiment performs background area detection on a first detection image, and determines a background area of the first detection image and an area of the background area. The area is compared with a preset area, which may be 60% of the total area of the first detection image, for example. Under the condition that the area is larger than the preset area, the area occupied by the background area in the first detection image is relatively large, and when the fault of the insulator string is determined through the first detection image, the background area in the first detection image has relatively small influence on the fault detection of the insulator string even if the background area is not clear. Therefore, the background area in the first detection image is compressed, so that the data size of the first image is reduced, and meanwhile, the confirmation of the faults of the insulator string is not influenced. When the area is smaller than the preset area, the area occupied by the background area in the first detection image is relatively small, and at this time, in order to ensure the fault detection accuracy of the insulator string, the first detection image does not need to be compressed. By compressing the background area of the first detection image, the data size of the first detection image is reduced, and the transmission rate of the first detection image is improved under the condition that the fault detection of the insulator string in the first detection image is not affected.
In some embodiments, the determining that the insulator string is leaky includes: and determining that the insulator string is leaked in response to determining that the leakage current is greater than or equal to a preset leakage current.
In this embodiment, in the case where a relatively large leakage current occurs in the insulator string, it is indicated that the insulator string at this time may be relatively greatly affected by environmental factors but does not cause a failure, and it is also indicated that the insulator string at this time may have a failure. Therefore, it is necessary to judge the leakage current of the insulator string to determine whether the insulator string has a possibility of malfunction. Under the condition that the leakage current is larger than the preset leakage current, the leakage current is relatively large at the moment, so that the occurrence of electric leakage of the insulator string is determined, and at the moment, the possibility of failure of the insulator string is high. The preset leakage current is determined according to historical experience, and the purpose of accurately determining the occurrence of electric leakage of the insulator string is achieved through comparison of the leakage current and the preset leakage current.
In some embodiments, the method further comprises: periodically acquiring a second image corresponding to the insulator string; comparing the second image with a preset image, and acquiring second detection data of the insulator string in response to determining that the similarity of the second image and the preset image is smaller than the preset similarity; superposing the second detection data on the second image to obtain a second detection image; and sending the second detection image to the data processing terminal so as to determine a second fault of the insulator string in the second detection image through the data processing terminal.
In this embodiment, a second image of the insulator string is periodically acquired to achieve the purpose of periodic detection of the insulator string, where the second image includes an internal image of the insulator string and/or an external image of the insulator string. In the case that the insulator string is not faulty, the periodically obtained second image is unbroken, which would lead to a waste of communication resources if the unbroken image were to be sent to the data processing terminal. Therefore, the second image is compared with the predetermined image, and it is to be noted that, when the second image includes the internal image of the insulator string, the predetermined image associated with the internal image is compared, where the compared predetermined image is an image in which no breakage occurs inside the insulator string; in the case that the second image includes an external image of the insulator string, a comparison is performed with a predetermined image associated with the external image, wherein the compared predetermined image is an image in which breakage does not occur outside the insulator string. And under the condition that the similarity between the second image and the preset image is smaller than the preset similarity, the fact that the insulator string in the second image is broken is indicated, and under the condition, the second image is required to be sent to the data processing terminal. In order to more accurately determine the faults of the insulator string, second detection data of the insulator string are also required to be acquired, and the second detection data are superimposed on the second image to obtain a second detection image. And sending the second detection image to a data processing terminal, and determining whether the insulator string in the second detection image has faults or not by using the data processing terminal. And in the case that the insulator string fails, determining the failure as a second failure, wherein the second failure is at least one type of failure of all failure types of the insulator string. The second detection image is sent to the data processing terminal, so that the purposes of greatly saving communication flow and reducing the number of invalid alarms are achieved.
The second detection image is also subjected to the compression processing described above. Because the second detection image is compressed, the data size of the second detection image is relatively small, and therefore, the detection period of the insulator string can be shortened when the insulator string is subjected to fault detection in daily life. The detection period can be shortened from 30min to 5min, so that the monitoring beat frequency is improved by 6 times, the daily uploading frequency can be reduced by 4 times, only the hidden danger data are uploaded through the data fusion section identification, the shooting frequency is enhanced, the uploading frequency is reduced, and therefore the power consumption of the device is reduced, the network flow is reduced, and the real-time performance of hidden danger early warning is improved.
The embodiment of the application provides a fault detection method of an insulator string in a power transmission line, which is applied to a data processing terminal, and referring to fig. 2, the method comprises the following steps:
step 201, receiving a first detection image or a second detection image sent by a data fusion end.
In this step, since the power transmission line is relatively long, and thus the number of the insulator strings in the power transmission line is relatively large, if only the data processing terminal is used to determine the failure of the insulator string, the processing pressure of the data processing terminal will be relatively large, and the operation speed will be relatively low, so that the efficiency of determining the failure of the insulator string is low. Therefore, the data fusion end is utilized to determine faults of the insulator strings in the first detection image and the second detection image. The data processing terminal receives the first detection image or the second detection image sent by the data fusion terminal, so that the purpose of reducing the processing pressure of the data processing terminal is achieved.
Step 202, identifying the first detection image to determine a first fault of the insulator string in the first detection image. Or alternatively, the first and second heat exchangers may be,
in this step, the first detection image includes first detection data and a first image associated with the insulator string, where whether the insulator string has a fault may be determined by the first detection data, and, for example, in a case where the first detection data is temperature data, if the temperature data is greater than predetermined temperature data, it is indicated that the insulator string may have a fault. From the first image, the degree of breakage of the insulator string can be determined.
