It should be noted that, for those of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present application.

[0042] Figure 1 The invention shows an adaptive detection device for insulating gas in high-voltage electrical equipment provided by an embodiment of the present application. Figure 1 The insulating gas adaptive detection device for high-voltage electrical equipment includes an insulating gas detection chamber 20, a measuring module (not shown in the figure) and a control device 30. The insulating gas detection chamber 20 is connected to the gas chamber 10 of the high-voltage electrical equipment through a pipeline, and a first solenoid valve 21 is arranged on the pipeline between the insulating gas detection chamber 20 and the gas chamber 10 of the high-voltage electrical equipment. The measuring module is arranged in the insulating gas detection chamber 20, and the measuring module includes a purity detection unit, a trace water content detection unit, an oxygen detection unit, a sulfur dioxide detection unit and a carbon monoxide detection unit.

[0043] The control device 30 is used to respond to the insulating gas detection instruction, control the first solenoid valve 21 to open, so that the insulating gas in the gas chamber 10 of the high-voltage electrical equipment enters the insulating gas detection chamber 20, and then control the first solenoid valve 21 to close.

[0044] Each detection unit in the measurement module is used to detect the insulating gas in the insulating gas detection chamber 20 and send the detection result to the control device 30 .

[0045] The control device 30 is also used to correct the detection result through a preset correction model and display the corrected detection result. Each detection result corresponds to a preset correction model, and each preset correction model is trained based on the measurement value of the insulating gas by each detection unit and the corresponding theoretical value.

[0046] In the embodiment of the present application, a correction model is obtained by training the measured values ​​of the insulating gas and the corresponding theoretical values ​​of each detection unit, and then the correction model is used to correct the detection results of each detection unit of the detection module. This can improve the detection accuracy of each detection unit of the detection module and make the error between the detected insulating gas value and the true value smaller.

[0047] Exemplarily, the purity detection unit, the trace water content detection unit, the oxygen detection unit, the sulfur dioxide detection unit and the carbon monoxide detection unit can all be realized by corresponding sensors.

[0048] In some embodiments, the process of the control device 30 training the preset correction model may include:

[0049] Obtaining measurement values ​​of the insulating gas sample gas measured by each detection unit of the measurement module under multiple external environmental parameters, the measurement values ​​including gas composition, sulfur hexafluoride concentration and insulating gas humidity of the insulating gas, the multiple external environmental parameters including temperature and air pressure;

[0050] Generate training samples using the measured values, theoretical values ​​of the insulating gas sample gas under the multiple external environmental parameters, and the multiple external environmental parameters, and divide the training samples into a test set and a validation set; wherein the theoretical values ​​include gas composition of the insulating gas, sulfur hexafluoride concentration, and insulating gas humidity;

[0051] The test set and the validation set are used to train a preset correction model, which is a deep learning model.

[0052] In this embodiment, the measured values, the theoretical values ​​of the insulating gas sample gas under a variety of external environmental parameters, and a variety of external environmental parameters are used to generate training samples, and the preset correction model is trained through the training samples, so that the preset correction model can obtain the error pattern between the measured values ​​and the theoretical values ​​measured by the measurement module when the external environment changes greatly, such as under conditions of low pressure in the plateau or under conditions of large temperature difference between day and night, and then the measurement results of the measurement module are compensated by the trained preset correction model, thereby improving the detection accuracy and making the error between the detected insulating gas value and the true value smaller.

[0053] Exemplarily, the process of measuring the insulating gas sample gas under multiple external environmental parameters may include:

[0054] Assuming that there are M kinds of insulating gas sample gases, each insulating gas sample gas has a certain theoretical value, and the M kinds of insulating gas sample gases are divided into N groups, and the values ​​of the first factor in the theoretical value between various insulating gas sample gases in each group of insulating gas sample gases change while the values ​​of the other two second factors remain unchanged, the first factor is any one of gas composition, sulfur hexafluoride concentration and insulating gas humidity, M and N are both integers greater than 2, and M is greater than N;

[0055] For each insulating gas sample gas in each group of insulating gas sample gases, the insulating gas sample gas is input into each detection unit of the measurement module under various external environmental parameters of the plurality of external environmental parameters, and each detection unit detects and outputs a corresponding measurement value.

[0056] Specifically, the three factors of the gas composition of the insulating gas, the sulfur hexafluoride concentration and the insulating gas humidity in the theoretical value and the measured value can be divided into the first factor and the second factor, the first factor is any one of the three factors, and the second factor is two factors of the three factors except the first factor. The values ​​of the first factors of various insulating gas sample gases in each group of insulating gas sample gases change while the values ​​of the two second factors remain unchanged, thereby forming a group of insulating gas sample gases, and the first factors of each group of insulating gas sample gases are different.

[0057] For example, the gas components of various insulating gas sample gases in the first group of insulating gas sample gases are different, but the sulfur hexafluoride concentration and the insulating gas humidity are the same. For example, the first group of insulating gas sample gases has a kinds of insulating gas sample gases, that is, the a gas components of the a kinds of insulating gas sample gases are different, and the a gas components can be values ​​within the range of gas components that can be encountered in actual production work. Afterwards, the a kinds of insulating gas sample gases in the first group of insulating gas sample gases are input into each detection unit of the measurement module under various external environmental parameters of a variety of external environmental parameters, and each detection unit detects and outputs the corresponding measurement value. For example, b kinds of external environmental parameters are set, and each kind of insulating gas sample gas in the a kinds of insulating gas sample gases is input into each detection unit of the measurement module under b kinds of external environmental parameters, and each detection unit detects and outputs the corresponding measurement value. Each insulating gas sample gas obtains b measurement values. In the above, a and b are both positive integers.

[0058] The above description is based on the example that the first factor is the gas composition and the second factor is the sulfur hexafluoride concentration and the insulating gas humidity. For the case where the first factor is the sulfur hexafluoride concentration and the second factor is the gas composition and the insulating gas humidity, and for the case where the first factor is the insulating gas humidity and the second factor is the gas composition and the sulfur hexafluoride concentration, the description will not be repeated, and the previous paragraph can be referred to.

[0059] In this embodiment, by setting multiple external environmental parameters, each insulating gas sample gas is input into each detection unit of the measurement module under various external environmental parameters for measurement to obtain multiple measurement values, which can reflect the impact of external environmental parameters on the measurement values.

[0063] At a first air pressure and standard temperature, the insulating gas sample gas is input into each detection unit of the measurement module to obtain the X+1th measurement value; at a second air pressure and standard temperature, the insulating gas sample gas is input into each detection unit of the measurement module to obtain the X+2th measurement value; at a Yth air pressure and standard temperature, the insulating gas sample gas is input into each detection unit of the measurement module to obtain the X+Yth measurement value; wherein, the first air pressure is the lowest air pressure of the external environment, the Yth air pressure is the highest air pressure of the external environment, the second air pressure to the Y-1th air pressure are between the first air pressure and the Yth air pressure, and Y is an integer greater than 3.

[0068] For example, the vacuum unit 40 evacuates the insulating gas detection chamber 20. After the evacuation is completed, the control device 30 controls the first solenoid valve to open, and the insulating gas in the gas chamber 10 of the high-voltage electrical equipment rushes into the insulating gas detection chamber 20. Afterwards, the vacuum unit 40 evacuates the insulating gas detection chamber 20 again. After the evacuation is completed, the control device 30 responds to the insulating gas detection instruction again.
