[0043] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] The GIS device fault detection method provided by the embodiments of the present application can be applied to an application environment as Figure 1 shown. Among them, the terminal 102 communicates with the server 104 through a network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or placed in the cloud or other network servers. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, projection devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted device can be a virtual reality (VR) device, an augmented reality (AR) device, a smart glasses, etc. The server 104 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0045] In an exemplary embodiment, as Figure 2 shown, a GIS device fault detection method is provided. Taking the method applied to the Figure 1 terminal 102 as an example, the method includes the following steps 202 to 206. Among them:

[0046] Step 202, input the target gas in the GIS device into the ultraviolet spectrum detection module to obtain the ultraviolet absorption spectrum of the target gas, and analyze the composition and mixing ratio of the target gas based on the ultraviolet absorption spectrum.

[0047] Among them, the GIS device is a gas-insulated enclosed combined electrical apparatus. The target gas is the environmental protection gas in the GIS device.

[0048] Exemplarily, the target gas in the GIS device is input into the ultraviolet spectrum detection module. Through the ultraviolet spectrometer in the ultraviolet spectrum detection module, the ultraviolet absorption spectrum obtained when the target gas is irradiated by the ultraviolet light source in the ultraviolet spectrum detection module is collected. According to the position and intensity of the absorption peaks in the ultraviolet absorption spectrum, the composition components and mixing ratio of the target gas are determined.

[0049] Step 204, when the change in the mixing ratio relative to the reference mixing ratio exceeds the preset ratio range, the target gas is input into the infrared spectrum detection module to obtain the infrared absorption spectrum of the target gas. Based on the infrared absorption spectrum, the corresponding concentration of the composition components of the target gas is analyzed.

[0050] Among them, the reference mixing ratio is the mixing ratio of the target gas in the GIS device when the GIS device has no faults.

[0051] Optionally, when the change in the mixing ratio of the target gas relative to the reference mixing ratio exceeds the preset ratio range, the infrared absorption spectrum obtained when the target gas is irradiated by the infrared light source in the infrared spectrum detection module is collected through the infrared spectrometer in the infrared spectrum detection module. According to the position and intensity of the absorption peaks in the infrared absorption spectrum, the corresponding concentration of the composition components of the target gas is determined.

[0052] In one embodiment, if the change in the mixing ratio of the target gas relative to the reference mixing ratio is within the preset ratio range, the GIS device has no faults and operates normally.

[0053] Step 206, when the change in the corresponding concentration relative to the reference concentration exceeds the preset concentration range, it is determined that the GIS device has a fault.

[0054] Among them, the reference concentration is the corresponding concentration of the composition components of the target gas in the GIS device when the GIS device has no faults.

[0055] Exemplarily, when the change in the corresponding concentration of the composition components of the target gas relative to the reference concentration exceeds the preset concentration range, the GIS device has a fault.

[0056] In another embodiment, when the change in the corresponding concentration of the composition components of the target gas relative to the reference concentration is within the preset concentration range, the GIS device has no faults.

[0057] In the above GIS equipment fault detection method, the target gas in the GIS equipment is input into the ultraviolet spectrum detection module to obtain the ultraviolet absorption spectrum of the target gas. Based on the ultraviolet absorption spectrum, the composition and mixing ratio of the target gas are analyzed. When the change in the mixing ratio relative to the reference mixing ratio exceeds the preset ratio range, the target gas is input into the infrared spectrum detection module to obtain the infrared absorption spectrum of the target gas. Based on the infrared absorption spectrum, the corresponding concentration of the composition of the target gas is analyzed. When the change in the corresponding concentration relative to the reference concentration exceeds the preset concentration range, it is determined that the GIS equipment has a fault. In this way, by combining the ultraviolet spectrum detection module and the infrared spectrum detection module to detect the target gas in the GIS equipment, the detection of GIS equipment faults is made more accurate.

[0058] In an exemplary embodiment, the ultraviolet spectrum detection module includes an ultraviolet light source and an ultraviolet spectrometer. Inputting the target gas in the GIS equipment into the ultraviolet spectrum detection module to obtain the ultraviolet absorption spectrum of the target gas, and analyzing the composition and mixing ratio of the target gas based on the ultraviolet absorption spectrum includes: collecting the ultraviolet absorption spectrum of the target gas obtained under the irradiation of the ultraviolet light source by the ultraviolet spectrometer, and determining the composition and mixing ratio of the target gas according to the position and intensity of the absorption peaks in the ultraviolet absorption spectrum.

[0059] Among them, the ultraviolet spectrum detection module includes an ultraviolet light source, an ultraviolet spectrometer, an optical fiber, a gas cell, an exhaust sub-module, and a gas pipe.

[0060] In actual implementation, the ultraviolet light source is connected to the gas cell through an optical fiber, the ultraviolet spectrometer is connected to the gas cell through an optical fiber, and the gas cell, the exhaust sub-module, and the GIS equipment are connected through a gas pipe. The specific connection diagram is as Figure 3 shown.

[0061] In some embodiments, the ultraviolet absorption spectrum of the target gas obtained under the irradiation of the ultraviolet light source within a specific wavelength range is collected by the ultraviolet spectrometer. Different gas molecules have unique absorption peaks on the ultraviolet absorption spectrum. The position of the absorption peak is compared with the standard spectral library to determine the composition of the target gas, and then the mixing ratio of the target gas is determined according to the intensity of the absorption peak.

[0062] In the above embodiment, by detecting the mixing ratio of the environmental protection gas in the environmental protection GIS through the ultraviolet spectrum detection module, it is possible to preliminarily determine whether a discharge fault has occurred, so as to perform the next operation.

[0063] In an exemplary embodiment, the infrared spectroscopy detection module includes an infrared light source and an infrared spectrometer; the target gas is input into the infrared spectroscopy detection module to obtain the infrared absorption spectrum of the target gas, and based on the infrared absorption spectrum, the corresponding concentration of the components of the target gas is analyzed, including: collecting the infrared absorption spectrum of the target gas obtained under the irradiation of the infrared light source by the infrared spectrometer, and determining the corresponding concentration of the components of the target gas according to the position and intensity of the absorption peaks in the infrared absorption spectrum.

[0064] Among them, the infrared spectroscopy detection module includes an infrared light source, an infrared spectrometer, an optical fiber, a gas cell, an exhaust sub-module, and a gas pipe.

[0065] In actual implementation, the infrared light source is connected to the gas cell through an optical fiber, the infrared spectrometer is connected to the gas cell through an optical fiber, and the gas cell, the exhaust sub-module, and the GIS device are connected to each other through a gas pipe. The specific connection diagram is as Figure 4 shown.

[0066] In some embodiments, the infrared absorption spectrum of the target gas obtained under the irradiation of the infrared light source is collected by the infrared spectrometer, each absorption peak is identified, and the corresponding concentration of the components of the target gas is determined according to the position and intensity of the absorption peaks in the infrared absorption spectrum.

[0067] In the above embodiment, the target gas is detected by the infrared spectroscopy detection module, the instrument is simple, the operation cost is low, and the efficiency of fault detection is accelerated.

[0068] In an exemplary embodiment, the GIS device fault detection method further includes: generating a real-time log based on the ultraviolet absorption spectrum and the infrared absorption spectrum of the target gas; the real-time log includes the components, mixing ratio, corresponding concentration of the components, change value of the mixing ratio, and change value of the corresponding concentration in the target gas.

[0069] In actual implementation, based on the ultraviolet absorption spectrum and the infrared absorption spectrum of the target gas, the components, mixing ratio, corresponding concentration of the components, change value of the mixing ratio, and change value of the corresponding concentration in the target gas are generated.

[0070] In the above embodiment, by outputting the log, it can help the terminal quickly locate and diagnose problems. When the GIS device fails, the log provides an important clue for tracing the root cause of the problem.

[0071] In an exemplary embodiment, before inputting the target gas in the GIS device into the ultraviolet spectroscopy detection module, it includes: collecting the gas to be measured in the GIS device, filtering the particulate matter, moisture, and noise in the gas to be measured, and eliminating background interference to obtain the target gas.

[0072] In actual implementation, the gas to be measured in the GIS device is collected, the particulate matter, moisture, and noise in the gas to be measured are filtered, and the background interference is eliminated to obtain the target gas. Among them, the background interference is useless gases such as CO2 and H2O.

[0073] In the above embodiment, by filtering the interfering substances in the gas to be measured, the finally measured result is more accurate.

[0074] In an exemplary embodiment, the process of determining the reference mixing ratio and the reference concentration includes: collecting the sample gas of the GIS device under normal operating conditions, inputting the sample gas into the ultraviolet spectroscopy detection module and the infrared spectroscopy detection module respectively, obtaining the sample ultraviolet absorption spectrum and the sample infrared absorption spectrum of the sample gas, and determining the reference mixing ratio and the reference concentration of the sample gas according to the sample ultraviolet absorption spectrum and the sample infrared absorption spectrum.

[0075] In actual implementation, the sample gas of the GIS device under normal operating conditions is collected, the sample gas is input into the ultraviolet spectroscopy detection module and the infrared spectroscopy detection module respectively, the sample ultraviolet absorption spectrum and the sample infrared absorption spectrum of the sample gas are obtained, and the reference mixing ratio and the reference concentration of the sample gas are determined according to the sample ultraviolet absorption spectrum and the sample infrared absorption spectrum.

[0076] In the above embodiment, by setting the reference mixing ratio and the reference concentration, the finally determined change is more in line with the actual situation, and the result of the fault detection is more accurate.

[0077] To illustrate the GIS device fault detection method in the present application in detail, an embodiment is used for illustration below. The specific flowchart is as Figure 5 shown. Exemplarily, the present application illustrates the GIS device fault detection method in a specific scenario.

[0078] First, the gas to be measured in the GIS device is collected, the particulate matter, moisture, and noise in the gas to be measured are filtered, and the background interference is eliminated to obtain the target gas. Among them, the background interference is useless gases such as CO2 and H2O.

[0079] The target gas in the GIS device is input into the ultraviolet spectroscopy detection module. Through the ultraviolet spectrometer in the ultraviolet spectroscopy detection module, the ultraviolet absorption spectrum obtained by irradiating the target gas with the ultraviolet light source in the ultraviolet spectroscopy detection module is collected. According to the position and intensity of the absorption peak in the ultraviolet absorption spectrum, the composition and mixing ratio of the target gas are determined.

[0080] When the change in the mixing ratio of the target gas relative to the reference mixing ratio exceeds the preset ratio range, an infrared absorption spectrum of the target gas obtained under the irradiation of an infrared light source in the infrared spectrum detection module is collected by an infrared spectrometer in the infrared spectrum detection module, and the corresponding concentration of the constituent components of the target gas is determined according to the position and intensity of the absorption peaks in the infrared absorption spectrum.

[0081] When the change in the corresponding concentration of the constituent components of the target gas relative to the reference concentration exceeds the preset concentration range, the GIS device fails.

[0082] In this application, a ultraviolet spectrum detection module is used to measure the mixing ratio in real time and preliminarily judge whether a failure occurs. The infrared spectrum detection module targets the target gas, accurately identifies the decomposition products through characteristic vibration peaks, detects its constituent components and concentration changes, and accurately judges whether a discharge failure occurs.
