[0002] Due to the particularity of the internal structure of 110kV and above high-voltage cables and extra-high voltage cables, after the semi-conductive buffer water-blocking tape absorbs water and expands, the resistance of the semi-conductive water-blocking tape increases and the conductivity performance deteriorates, causing a potential difference between the semi-conductive shielding layer of the cable insulation and the aluminum sheath when the cable is put into operation. If the cable sheath is grounded, the capacitive current of the cable will increase, causing the aluminum sheath to discharge to the semi-conductive water-blocking tape and the semi-conductive layer of the cable insulation, endangering the safe operation of the cable.

[0038] In the above operating environment, the present application provides a method for detecting moisture in a high-voltage cable, as shown in the following. Figure 2 Figure 2 is a flowchart of a method for detecting moisture in a high-voltage cable according to an embodiment of the present application.

[0039] In step S201, gas information of a target gas is obtained, wherein the target gas refers to a gas in a sheath buffer layer of the high-voltage cable, and the gas information includes at least one of the following: gas temperature information and gas composition information.

[0040] Optionally, an electronic device, an application system, a server, or the like can be used as an execution subject of the present application. In this embodiment, a processor in a moisture analyzer is used as the execution subject to execute the above method for detecting moisture in a high-voltage cable.

[0041] Optionally, the processor can obtain gas information of a target gas, wherein the target gas refers to a gas in a sheath buffer layer of the high-voltage cable, and the sheath buffer layer is located between an insulation shielding layer and a metal sheath of the high-voltage cable, and the main functions of the sheath buffer layer include electrical conduction, mechanical buffering, and longitudinal water blocking.

[0042] Optionally, the gas information includes at least one of the following: gas temperature information and gas composition information. The gas temperature includes a dry-bulb temperature and a wet-bulb temperature of the target gas, and the gas composition information is used to represent chemical compositions in the gas, such as alkane content, hydrogen content, sulfur content, and the like.

[0043] In step S202, the gas information is processed by a moisture detection model to obtain a detection result, wherein the detection result represents a moisture index corresponding to the sheath buffer layer.

[0044] ​Optionally, the moisture detection model can be a neural network model, and the processor can input the gas information to the moisture detection model, so as to output a detection result through the moisture detection model. The detection result represents a moisture index corresponding to the buffer layer of the sheath. The moisture index is used to represent the moisture degree of the buffer layer of the sheath.

[0045] In an optional embodiment, the moisture detection model can be obtained by training in the following manner: obtaining a training sample set, wherein a training sample in the training sample set includes sample gas information of a sample gas, the sample gas refers to a gas in a sample buffer layer of a sample high-voltage cable, a true label of the training sample is a moisture index of the sample buffer layer, and the sample gas information is in the same form as the gas information.

[0046] In an optional embodiment, the moisture detection model is a convolutional neural network model. For example, the moisture detection model includes 1 input layer, 2 convolutional layers, 2 Relu nonlinear activation layers, 2 pooling layers, 1 fully connected layer, and 1 output layer. Optionally, the number of convolutional kernels is 4, 8, and 16, and the size is 3*3. In order to make the feature extraction show a nonlinear relationship, an activation function is followed after each convolutional layer, and a Relu activation function is used. Two pooling layers select maximum pooling with a size of 2*2 and a step of 1. The fully connected layer is used to write the features extracted through the convolutional layer and the pooling layer into a one-dimensional vector form, and is fully connected with 4 nodes of the output layer, so as to achieve the purpose of moisture index evaluation.

[0047] In an optional embodiment, in the processing of the moisture detection model, the sample data matrix output by the convolutional layer is input to the pooling layer, the sample data matrix is divided into a plurality of data sub-matrices in the pooling layer, a sample data is randomly extracted from each data sub-matrix, a pooling matrix is generated according to each extracted sample data, and the pooling matrix is taken as the output of the pooling layer. For example, in the process of pooling, the sample data matrix output by the first convolutional layer is input to the first pooling layer after being activated. In the first pooling layer, the sample data matrix is divided into a plurality of sub-matrices, a sample data is randomly extracted from each data sub-matrix, and a pooling matrix is generated according to the extracted picture sample data. After the first pooling layer outputs, the data output by the first pooling layer is input to the second convolutional layer for convolution, the data output by the second convolutional layer is randomly activated, and the randomly activated data is input to the second pooling layer for pooling processing. The pooling processing result is taken as the output of the model layer pooling.

[0048] Optionally, the humidity detection model can include two stages of forward propagation training and back propagation network training in the training process. The forward propagation network training refers to a process in which the model processes input data to obtain an output result. The back propagation network training is a process of updating the parameters of the convolutional layer by using a stochastic gradient descent optimization algorithm for back propagation network training when the output result of the forward propagation network training does not match the expected output. In the error calculation of the actual output and the expected output of the model, a mean square error loss function can be used.

[0049] In step S203, it is determined whether the high-voltage cable is wet based on the detection result.

[0050] Optionally, the humidity index in the detection result is in the interval [0, 1].

[0051] Optionally, the target processing system can compare the detection result with a preset threshold, and determine whether the high-voltage cable is wet based on the comparison result.

[0052] In the embodiments of the present application, by obtaining the gas information of the target gas, the information reflecting the humidity of the sheath buffer layer of the high-voltage cable is effectively obtained. By using the humidity detection model to process the gas information, the detection result is obtained, the automatic analysis of the gas information by the model is realized, the humidity index corresponding to the sheath buffer layer is obtained, and thus on the one hand, the accuracy of the moisture test can be effectively improved when the moisture test result of the high-voltage cable is determined based on the detection result, and on the other hand, the moisture test efficiency can be improved.

[0053] Therefore, the method provided by the present application achieves the purpose of moisture testing of the sheath buffer layer of the high-voltage cable by the model, realizes the technical effect of improving the moisture testing accuracy, and solves the technical problem of low accuracy in the related art.

[0054] Optionally, in the moisture testing method of the high-voltage cable provided in the embodiments of the present application, obtaining the gas information of the target gas includes: measuring the temperature of the target gas by a first thermometer in the temperature detector to obtain the dry-bulb temperature of the target gas; measuring the temperature of the target gas by a second thermometer in the temperature detector to obtain the wet-bulb temperature of the target gas; determining the gas temperature information according to the dry-bulb temperature and the wet-bulb temperature; performing component analysis processing on the target gas by a gas component analyzer to obtain gas component information; and determining at least one of the gas temperature information and the gas component information as the gas information.

[0055] Optionally, the first thermometer is equivalent to a dry-bulb thermometer, which is a commonly used standard thermometer for measuring the dry-bulb temperature of the gas, i.e. the true temperature not affected by moisture. The dry-bulb thermometer is usually exposed to the gas environment and directly reads the temperature value of the gas.

[0056] Optionally, the second thermometer functions as a wet-bulb thermometer, which measures the wet-bulb temperature of the gas using a moistened gauze or sponge wrapped around the thermometer probe. The wet-bulb temperature is lower than the dry-bulb temperature, and the difference depends on the humidity of the gas. The difference between the wet-bulb and dry-bulb temperatures can be used to calculate the dew point temperature and relative humidity, thereby estimating the moisture content of the gas.

[0057] In an optional embodiment, the dry-bulb temperature and the wet-bulb temperature may be directly determined as the gas temperature information.

[0058] In an optional embodiment, a barometer may be used to measure the current atmospheric pressure, and then the dry-bulb temperature, wet-bulb temperature, and atmospheric pressure may be determined as the gas temperature information.

[0059] Alternatively, a gas analyzer is an instrument used to analyze the content of each component in a gas mixture. It can accurately determine the various chemical components in the gas. Therefore, the target gas can be analyzed by the gas composition analyzer to obtain gas composition information.

[0060] After the gas temperature information and the gas composition information are determined, at least one of the gas temperature information and the gas composition information may be determined as the gas information.

[0061] It should be noted that, through the above method, accurate determination of gas temperature information and gas composition information is achieved, thereby improving the accuracy of tide measurement.

[0062] Optionally, in the moisture testing method for high-voltage cables provided in an embodiment of the present application, determining whether the high-voltage cable is damp is determined based on the test results, including: comparing the moisture index in the test results with a preset index; when the moisture index is greater than the preset index, determining that the high-voltage cable is damp; when the moisture index is less than or equal to the preset index, determining that the high-voltage cable is not damp.

[0063] Optionally, the preset index may be preset manually.

[0064] For example, assuming the preset index is 0.5, when the moisture index in the detection result is 0.7, it is determined that the high-voltage cable is damp, and when the moisture index in the detection result is 0.3, it is determined that the high-voltage cable is not damp.

[0065] It should be noted that, through the above method, it is possible to determine whether the high-voltage cable is damp based on a numerical comparison method, thereby further improving the accuracy of tide detection.

[0066] Optionally, in the high-voltage cable moisture testing method provided in an embodiment of the present application, after determining whether the high-voltage cable is damp based on the detection results, the method further includes: generating an early warning signal when it is determined that the high-voltage cable is damp, wherein the early warning signal is used to control the early warning light for early warning.

[0067] Optionally, when the high-voltage cable is determined to be damp, the processor may generate a warning signal. The processor is electrically connected to a warning light, and the processor may transmit the warning signal to the warning light to control the warning light to issue a warning. For example, upon receiving the warning signal, the warning light may flash or continuously illuminate to issue a warning.

[0068] It should be noted that through the above method, when the high-voltage cable is detected to be damp, the early warning signal is automatically triggered and the early warning light is controlled to work, thereby providing instant visual feedback to on-site operators, facilitating timely maintenance of the cable by the staff, thereby improving the reliability of high-voltage cable operations.

[0069] It can be seen that the method provided in this application achieves the purpose of performing tide detection based on the gas information in the sheath buffer layer of the high-voltage cable through a model, realizes the technical effect of improving the accuracy of tide detection, and solves the technical problem of low accuracy in the related art when performing tide detection on high-voltage cables.

[0070] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
