It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
[0032] Figure 1 is a flow chart of a method for detecting a state of a switch cabinet device according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:
[0033] Step S102: obtaining the operating status of the switch cabinet device to be detected.
[0034] In the technical solution provided in step S102 of the embodiment of the present invention, the switch cabinet device may also be referred to as a switch cabinet, which may be referred to as a device in the embodiment of the present invention. The operating status indicates whether the switch cabinet device is operating, which may also be referred to as a device status.
[0035] In this embodiment, the operating state of the switch cabinet device to be detected can be determined, that is, whether the device is in operating state.
[0036] Optionally, in the embodiment of the present invention, the operating status of the switch cabinet equipment can be obtained through the energy management system, and it can be determined whether the equipment status is not operating.
[0037] Step S104: in the operating state, determining the gas concentration of the gas generated in the switch cabinet equipment.
[0038] In the technical solution provided in the above step S104 of the embodiment of the present invention, the gas may also be referred to as a product. The gas generated by the switch cabinet equipment may include oxygen ( )、Nitrogen( )、Carbon monoxide( ),ozone( ), nitric oxide ( ) and other gases, such as The gas concentration may be the gas concentration of each gas in the extracted gas, for example, The gas concentration can be , The gas concentration can be , The gas concentration can be , The gas concentration can be , The gas concentration can be , The gas concentration can be It should be noted that the above-mentioned gases and their corresponding gas concentrations are only for illustration and are not specifically limited here.
[0039] In this embodiment, after the operating state of the switch cabinet device to be detected is acquired, the generated gas can be extracted from the switch cabinet device under the corresponding operating state, and the gas concentration of each gas can be determined.
[0040] Optionally, for different operating states, corresponding sampling cycles can be performed to periodically extract gas from the switch cabinet equipment, and the components of the extracted gas can be detected to determine the gas concentration of each component.
[0041] In an embodiment of the present invention, a system capable of detecting the status of switch cabinet equipment may be provided, in which a sampler, an electronic valve, a pipeline, a multi-way conversion switch K1, a gas collecting device and a detection device may be deployed.
[0042] Optionally, a gas extraction device is arranged on the top of each switch cabinet to collect gas samples inside the switch cabinet. The gas extraction control is controlled by an electronic valve, which can control the gas extraction speed and time. The opening and closing of the electronic valve is centrally controlled by the data sampling device. This means that the extraction and stopping of gas inside each switch cabinet can be remotely controlled by the data sampling device. The pipeline through which the gas sampling flows is responsible for transmitting the collected gas samples to the subsequent analysis device or gas collection device for processing and analysis. The multi-way conversion switch can control the gas to enter the gas collection device as required. This means that different gas samples can be introduced into different analysis or gas collection devices by controlling the K1 switch for different types of detection or analysis. The detection device is used to detect the gas sample, and chromatography or other spectroscopic methods can be used for analysis. These methods are common gas detection technologies that can accurately analyze and detect gas components. Through these technologies, the components present in the gas, such as oxygen, carbon dioxide, etc., can be determined, so as to evaluate the state inside the switch cabinet.
[0043] Step S106, determining the gas composition change result and / or the gas conversion result based on the gas concentration.
[0044] In the technical solution provided in step S106 of the embodiment of the present invention, the composition change result can be used to indicate the stability of the gas composition and can be used to indicate abnormal changes in key components. The gas conversion result is used to determine the discharge mode of the switch cabinet equipment, and can determine the abnormal mode conversion of the product to determine the specific problem occurring in the switch cabinet.
[0045] In this embodiment, in the operating state, after the gas concentration of the gas generated in the switch cabinet device is determined, the gas composition change result and / or the gas conversion result can be determined based on the gas concentration.
[0046] Optionally, after determining the gas concentration, the problem inside the switch cabinet can be determined by comparing the abnormal changes in key components, that is, in the first judgment step, the result of the gas component change is obtained.
[0047] Optionally, the specific problem occurring in the switch cabinet can also be determined by determining the abnormal mode conversion of the product, that is, in the second step of determination, the gas conversion result is obtained.
[0048] Optionally, in the first step of judgment, it can be determined whether the stability of the gas product has changed, and whether there is a problem inside the switch cabinet. In the second step of judgment, the characteristic products in the product can be subdivided and judged, and the internal discharge mode and the specific situation inside the switch cabinet can be analyzed.
[0049] Step S108, based on the composition change result and / or the gas conversion result, the operating state is detected to obtain a detection result.
[0050] In the technical solution provided in the above step S108 of the embodiment of the present invention, the detection result is used to indicate whether the operating state is a normal operating state or an abnormal operating state. If the detection result shows that the operating state is a normal operating state, it can be said that there is no fault in the switch cabinet equipment, and the detection is determined to be normal. If the detection result shows that the operating state is an abnormal operating state, it can be said that there is a fault in the switch cabinet equipment, and the detection is determined to be abnormal.
[0051] In this embodiment, after determining the gas composition change result and the gas conversion result based on the gas concentration, the operating state can be detected based on the composition change result and / or the gas conversion result to obtain the detection result.
[0052] Optionally, the gas first enters the gas collection device through the K1 multiplexer. The gas collection device will transmit the collected gas to the detection device for quantitative gas phase component detection, which means that the various components in the gas can be accurately analyzed and measured. These components may include gas components such as oxygen, carbon dioxide, methane, and other possible harmful or abnormal gas components.
[0053] After the detection device completes the detection of gas phase components, it transmits the data to the gas phase component analysis and early warning device for comparative analysis. This analysis process may include comparison with known standard values or thresholds to determine whether there are abnormal conditions. The gas phase component analysis and early warning device will conduct comparative analysis based on the detection data and draw conclusions to determine whether the status inside the switch cabinet is normal.
[0054] Once the gas phase composition analysis and early warning device finds an abnormal situation, the system will immediately send an alarm message to the monitoring center or relevant personnel, and provide a detailed description of the abnormal situation and recommended treatment measures. This process can timely detect potential abnormal situations and take corresponding measures to improve the safety and stability of the power system.
[0055] The whole process demonstrates a complete gas sampling, analysis and early warning process. By quantitatively analyzing the gas composition and combining it with the preset algorithm for comparative analysis, potential abnormal situations can be discovered in a timely manner, that is, it can be determined whether the operating status is an abnormal operating status.
[0056] In step S102 to step S108 of the embodiment of the present invention, if it is necessary to detect the state of the switch cabinet equipment, it is possible to detect whether the switch cabinet equipment is running, and obtain the operating state of the switch cabinet equipment to be detected. In this operating state, the gas generated in the switch cabinet equipment can be extracted, and the gas concentration of the gas can be determined. According to the gas concentration, the stability of the gas composition can be determined, and the corresponding component change result can be obtained. According to the gas concentration, the discharge mode of the switch cabinet equipment can also be determined, and the corresponding gas conversion result can be obtained. Through the above-mentioned component change results and gas conversion results, the operating state is detected to determine whether there is a fault in the switch cabinet equipment. In the embodiment of the present invention, it is possible to accurately judge whether the equipment is faulty at the gas level in the switch cabinet equipment by determining the changes in the gas composition and whether the composition is abnormally converted, thereby achieving the technical effect of improving the accuracy of the state detection of the switch cabinet equipment and solving the technical problem of low accuracy of the state detection of the switch cabinet equipment.
[0057] The embodiment of the present invention is described in detail below in combination with the above steps.
[0058] As an optional embodiment, in the operating state, before determining the gas concentration of the gas generated in the switch cabinet equipment, the method also includes: in response to the operating state being a first operating state, controlling the exhaust device corresponding to the switch cabinet equipment, performing exhaust sampling once every first target time interval to obtain gas, wherein the first operating state is that the switch cabinet equipment is not operating; in response to the operating state being a second operating state, obtaining the maintenance status corresponding to the switch cabinet equipment, wherein the second operating state is used for the operation of the switch cabinet equipment; in response to obtaining the maintenance status, evaluating the switch cabinet equipment to obtain an evaluation result, and adjusting the maintenance frequency of the switch cabinet equipment according to the evaluation result; in response to the operating state being the second operating state, determining the operating time of the switch cabinet equipment.

If the operating state is the second operating state, the maintenance status corresponding to the switch cabinet equipment can be obtained, and the switch cabinet equipment can be evaluated based on the maintenance status to obtain an evaluation result, and the maintenance frequency of the switch cabinet equipment can be adjusted according to the evaluation result. When the operating state is the second operating state, the operating time of the switch cabinet equipment can be determined, wherein the first operating state can be that the switch cabinet equipment is not operating. The second operating state can be that the switch cabinet equipment is operating. The maintenance status can be used to indicate the equipment maintenance status. The first target duration can be a preset duration, or a duration set by itself according to actual conditions, for example, it can be preset to one week. It should be noted that the setting method and size of the above-mentioned first target duration are only for example illustration, and no specific restrictions are made here.

If the evaluation result is general, the detection frequency can be modified as needed. If the evaluation result is good, gas can be extracted according to a certain extraction sampling cycle.

[0063] In this embodiment, if the operation state is the second operation state, the operation time of the switch cabinet device can be determined. If the operation time is less than the operation time threshold, the operation state can be the first sub-operation state, and the exhaust device is controlled to perform exhaust sampling once every second target time interval to obtain gas. If the operation time is greater than or equal to the operation time threshold, the operation state is determined to be the second sub-operation state, and the exhaust device is controlled to perform exhaust sampling once every third target time interval to obtain gas.

After three consecutive times to ensure that the equipment is in normal operation, it is switched to normal operation mode. This method can ensure that the equipment is in a normal state in the initial stage after being put into operation, and warn and handle when an abnormality is detected.
[0066] Optionally, if the equipment is in normal operation, gas sampling is performed once a day, so as to ensure that the equipment status can be monitored at any time during normal operation of the equipment.
[0067] Optionally, after the equipment has completed the overhaul and maintenance, if the equipment evaluation result is good, the air extraction sampling is carried out in accordance with the normal operation mode. If the equipment is evaluated as fair after the overhaul and maintenance process is completed, the air extraction frequency is modified as needed.

[0087] As an optional embodiment, the gas conversion result is determined based on the change in gas concentration, including: in response to an increase in the gas concentration of nitric oxide in the gas and a decrease in the gas concentration of ozone in the gas to zero, determining that the discharge mode corresponding to the gas conversion result is arc discharge inside the switch cabinet equipment, and the discharge voltage and current are continuous discharge; in response to an increase in the gas concentration of ozone and the gas concentration of nitric oxide being zero, determining that the discharge mode corresponding to the gas conversion result is pulse discharge inside the switch cabinet equipment, and the discharge voltage and current are intermittent discharge.
[0088] In this embodiment, in the process of determining the gas conversion result based on the change in gas concentration, if the gas concentration of nitric oxide in the gas increases and the gas concentration of ozone in the gas decreases to zero, the discharge mode corresponding to the gas conversion result can be determined, and the discharge mode can be arc discharge inside the switch cabinet equipment, and the discharge voltage and current are continuous discharge. If the gas concentration of ozone increases and the gas concentration of nitric oxide is zero, the discharge mode corresponding to the masonry conversion result can be determined, and the discharge mode can be pulse discharge in the switch cabinet, and the discharge voltage and current are intermittent discharge.

[0091] In this embodiment, the operating state is detected based on the composition change result and / or the gas conversion result. In the process of obtaining the detection result, if the discharge mode is arc discharge inside the switch cabinet equipment, and the discharge voltage and current are continuous discharge, the abnormal operating state can be determined to be the first abnormal operating state. If the discharge mode is pulse discharge inside the switch cabinet, and the discharge voltage and current are intermittent discharge, the abnormal operating state can be determined to be the second abnormal operating state, wherein the abnormal operating state may include the first abnormal operating state and the second abnormal operating state. The severity of the first abnormal operating state is higher than the severity of the second abnormal operating state. The first abnormal operating state may also be called a serious fault.

[0093] In an embodiment of the present invention, if it is necessary to detect the state of the switch cabinet equipment, it is possible to detect whether the switch cabinet equipment is running, and obtain the operating state of the switch cabinet equipment to be detected.

[0094] Example 2
[0095] Another optional specific implementation is described in detail below.
[0096] At present, switchgear is an important type of electrical equipment in the power system. Due to the compact installation and closed installation method of switchgear, however, the number of actions in the switchgear is high, and in most cases the operation of the equipment cannot be monitored. Generally, problems can only be found in a power outage. There are a series of problems with the traditional manual inspection method. The panel indicator light only provides the working status of the switch structure, and the equipment status monitoring is not comprehensive enough. These problems may lead to the neglect of potential faults or delayed processing. Since the switchgear equipment is generally indoors, it affects the safety of the equipment.
[0097] In the related art, the current monitoring method generally measures the temperature through the periphery of the switch cabinet, or monitors the temperature and other signals inside the switch cabinet through some detectors. However, the installation position of the internal monitor is limited, and the temperature monitoring method through the periphery can only reflect the serious fault of the switch cabinet. The temperature monitoring method of the periphery cannot correctly reflect the minor fault. The internal detector is limited by the installation position and the partitions of each room. In many cases, it cannot monitor normally. However, the above methods still have problems such as incomplete monitoring, low efficiency and lack of real-time performance. That is, manual inspections have blind spots and cannot cover every detail. It is easy to ignore some potential fault points. Manual inspections require a lot of manpower and material resources, which is costly and cannot guarantee long-term high efficiency. Traditional methods cannot monitor the status of the switch cabinet in real time, and it is difficult to detect abnormal conditions in time and take measures. Therefore, there is still a technical problem of low accuracy in status detection of switch cabinet equipment.
[0098] The present invention proposes a switch cabinet monitoring method. The method provides a method and device capable of real-time monitoring of the switch cabinet state to solve the problems existing in the traditional manual inspection method. Through the flow sample collection and data analysis, the dynamic monitoring and early warning of the switch cabinet state are realized, and the safety and stability of the power system are improved, thereby achieving the technical effect of improving the accuracy of the state detection of the switch cabinet equipment and solving the technical problem of low accuracy of the state detection of the switch cabinet equipment.
[0099] The method is further described below.
[0100] In this embodiment, Figure 2 is a schematic diagram of a switch cabinet monitoring device according to an embodiment of the present invention. Figure 2 As shown, the device may include four switch cabinets, namely, switch cabinet 1, switch cabinet 2, switch cabinet 3 and switch cabinet 4. It may also include a sampler 201, an electronic valve 202, K1 203, a gas collection device 204, a detection device 205 and an analysis and early warning device 206, wherein a gas extraction device, namely, a sampler 201, is arranged on the top of each switch cabinet, and the gas extraction control is controlled by the electronic valve control 202. The opening and closing of the electronic valve 202 is centrally controlled by the data sampling device. The multi-way conversion switch K1 203 can control the gas to enter the gas collection device 204 as required.
[0101] Alternatively, if Figure 2 As shown, when the switch cabinet 1 needs to be evacuated, K1 203 first uses ambient gas to clean the pipeline, gas collecting device 204, detection device 205, etc. This is a good practice. By using ambient gas for cleaning, it can ensure that the pipeline and device are clean before sampling, avoiding residual gas or impurities that may affect the accuracy of sampling. After cleaning, actual gas sampling is performed through the sampler.
[0102] Optionally, FIG3 (a) is a schematic diagram of a gas collecting device according to an embodiment of the present invention. As shown in FIG3 (a), the gas collecting device 204 is used to collect sample gas or reference standard samples and store them in a specific area. A multi-bag design is adopted internally. This is because if each switch cabinet is assigned a gas collection interval, the device will be very large, and the frequency of gas sampling intervals will not be too high, resulting in interval differences in the sampling time of each switch cabinet. Therefore, the use of multi-bag air bags can save storage space and is also conducive to regular replacement and cleaning. FIG3 (b) is a schematic diagram of another gas collecting device according to an embodiment of the present invention. As shown in FIG3 (b), when the switch cabinet 1 needs to evacuate gas, K1 first cleans the pipeline, gas collecting device, detection device, etc. through ambient gas, that is, before each sampling, it will be cleaned by ambient gas first, and then through the sampler after completion. The storage area for sample gas or reference standard samples collected by the gas collecting device; a multi-bag air bag is used inside the gas collecting device. Because there are too many switch cabinets, if each switch cabinet is assigned a gas collection interval, the device will be larger and the frequency of gas sampling intervals will not be too high. There will be interval differences in the sampling time of each switch cabinet. Therefore, the use of multi-bag air bags can save storage space and is also conducive to regular replacement and cleaning.
[0103] In the embodiment of the present invention, the above-mentioned configuration takes into account the actual operation requirements and equipment management. By using a multi-bladder air bag, a large amount of gas samples can be managed and stored more effectively, while reducing the demand for storage space. This is very important for the long-term stable operation and maintenance of the equipment. Therefore, the design of the gas collection device takes into account both the convenience of operation and the actual operation of the equipment, which will help improve the efficiency and reliability of the sampling system.
[0104] Alternatively, if Figure 2 As shown, after the detection device 205 receives the gas sample, it can perform gas detection by chromatography or other spectroscopy. The analysis and early warning device 206 processes and analyzes the received data, evaluates the switch cabinet status through a preset algorithm, and identifies possible abnormal conditions. Once an abnormal condition is found in the switch cabinet, the system immediately sends an alarm message to the monitoring center or relevant personnel, and provides a detailed description of the abnormal condition and recommended treatment measures.

[0117] Step S406, modify the maintenance frequency as needed.
[0118] In this embodiment, the frequency of air extraction can be adjusted as needed.

[0121] Step S408, after three consecutive fifteen-minute gas samplings to ensure that the equipment is operating normally, it switches to normal operation mode.
[0122] In this embodiment, when the equipment is just put into operation, gas sampling is performed every 15 minutes.

[0127] In this embodiment, after the gas extraction sampling is completed, the gas enters the gas collecting device through the K1 multi-way conversion switch, and the gas collecting device transmits the sampled gas to the detection device for quantitative gas phase component detection. The gas phase component analysis and early warning device compares and analyzes the detection data to draw conclusions.
