In addition, the chemical properties of sulfur hexafluoride are very stable, so it is widely used as an insulating gas. Related power equipment includes sulfur hexafluoride relays, sulfur hexafluoride high-voltage circuit breakers, sulfur hexafluoride mutual conductance sensors, and sulfur hexafluoride lightning rods.

[0003] Although sulfur hexafluoride gas itself is not corrosive or toxic, it will decompose into highly toxic and corrosive harmful gas substances when a small amount of water vapor remains in the high-temperature and high-pressure gas chamber.

If sulfur hexafluoride gas is not effectively recovered, it will seriously endanger human health and promote the greenhouse effect.

[0078] In one embodiment, see Figure 1 In order to analyze the effectiveness of sulfur hexafluoride gas recovery and reuse, the present application provides a method for analyzing the effectiveness of sulfur hexafluoride gas recovery and reuse, including:

[0079] S101: performing pressure error prediction analysis according to physical indicator data of sulfur hexafluoride gas to obtain a pressure error prediction signal;

[0080] It can be understood that the collection content of physical indicator data, loss indicator data and gas quality data can be as follows: taking each sulfur hexafluoride gas recovery agency under the power grid as the object, collecting physical indicator data related to sulfur hexafluoride gas recovery; the physical indicator data is used to represent the basic characteristic information of each indicator of sulfur hexafluoride gas recovery; the physical indicator data includes but is not limited to measured pressure, measured temperature, molar volume and gas storage weight; the measured pressure is used to represent the actual pressure of sulfur hexafluoride gas storage; the measured temperature is used to represent the actual temperature of the sulfur hexafluoride gas storage environment; the molar volume is used to represent the value of 1 mole of sulfur hexafluoride gas contained in a unit gas storage volume; the gas storage weight includes the weight value before gas storage recovery and the weight value after gas storage recovery.

[0082] The total recovered gas storage situation of each recycling agency is randomly inspected, and gas quality data is generated accordingly; the gas quality data includes impurity component, total component amount, total base number and sampling number; the impurity component is used to represent the content data of various impurities in the sulfur hexafluoride gas after unit gas storage volume is recovered; the total component amount represents the total gas volume after unit gas storage volume is recovered; the total base number is used to represent the total base number of the recovered gas storage objects of each recycling agency; the sampling number is used to represent the sampling quantity of the recovered gas storage objects of each recycling agency.

[0083] Before performing step S101, it should be noted that i represents each recovery mechanism, j represents each impurity type, and ij represents each impurity type contained in the sulfur hexafluoride gas recovered by each recovery mechanism. When performing step S101, the specific operation steps of the pressure error prediction analysis process are as follows:

[0085] A2: Based on the formula The dynamic error value Hwc can be obtained i ; Set the dynamic error value Hwc i Compare with the corresponding error reference value (also called error threshold) Yu1; if the dynamic error value Hwc i < error reference value Yu1, a prediction precision signal is generated; if the dynamic error value Hwc i ≥ error reference value Yu1, a prediction deviation signal is generated.

[0086] S102: Based on the type of the pressure error prediction signal, perform a gas recovery quantitative analysis according to the physical indicator data or according to the physical indicator data and the loss indicator data to obtain a recovery rate result value of the sulfur hexafluoride gas;

[0087] It can be understood that when performing step S102, the specific steps of performing the gas recovery quantitative analysis process are as follows:

[0088] B1: When receiving the accurate prediction signal, retrieve the weight value before gas storage recovery and the weight value after gas storage recovery in the physical indicator data, and calibrate them as M respectively. i and M i ′, according to the formula Obtain the recovery value Hsl i , and the recovery value Hsl i Convert to recovery result value Zhs i Output;

[0089] B2: When receiving the prediction deviation signal, retrieve the weight loss value and air pressure loss value in the loss index data and calibrate them as Ms respectively. i and Ps i , according to the formula Calculate the loss value Sun i ;

Obtain w recycling amount values ​​Hsl in the historical recycling judgment set i , and 5≤w≤10, according to the formula Get the historical recovery mean Among them, w recovery values ​​Hsl i Expressed as {LHsl i1 , LHsl i2 , LHsl i3 ...LHsl iw};

[0091] B4: When generating the historical recovery mean Then, the loss value Sun generated in B2 is i and historical recovery mean Perform integrated analysis based on the formula Obtain the comprehensive value G i , comprehensive value G i Subtract the absolute value from the unit coefficient 1 to get |G i -1|, and |G i -1|Substitute into the preset threshold Yu2, if |G i -1| is within the preset threshold Yu2, a calculation valid signal is generated. i -1| is outside the preset threshold Yu2, a calculation invalid signal is generated;

[0092] B5: When generating a calculation valid signal, according to the formula Hsl′=1-|Sun i |, and obtain the predicted recovery value Hsl′, and use it as the recovery rate result value Zhs i When a calculation invalid signal is received, a quantitative error signal is generated.

[0093] S103: performing a purity sampling analysis based on the gas quality data of the sulfur hexafluoride gas to obtain a sampling pass rate;

[0094] It is understandable that when performing step S103, the specific operation steps of the purity sampling analysis process may be as follows:

[0095] C1: Randomly select some of the recovered gas storage conditions of each recovery agency, and obtain the impurity component and total component amount in the gas quality data based on this, and calibrate them as zsf ij and zcf i , according to the formula Obtain impurity contentzh i , the impurity content zh i Substitute the preset threshold value Yu3 for comparative analysis, and convert the impurity content exceeding the preset threshold value Yu3 intoi The number of gas storage objects calibrated as 1 in the random inspection of each recycling agency is summed up to obtain the unqualified base number Bg. i ;

[0096] C2: Obtain the sampling base number in the gas quality data of each recycling agency and calibrate the sampling base number as Zg i , according to the formula Calculate the sampling pass rate Coa i .

[0097] S104: Statistical analysis is performed on the recovery rate result values ​​and the sampling qualified rate to obtain a comprehensive analysis result of the effectiveness of sulfur hexafluoride gas recovery and reuse.

[0098] It is understandable that when performing step S104, the specific operation steps of the statistical analysis process are as follows:

[0099] D1: The recovery rate of sulfur hexafluoride gas in each recovery mechanism will be obtained. i Construct a bar chart, which can intuitively reflect the efficiency of sulfur hexafluoride gas recovery and reuse by each recovery agency;

[0100] D2: With each recycling organization i as the horizontal axis, the sampling qualified rate Coa i A two-dimensional coordinate system is constructed for the ordinate, and a qualified rate baseline is established on the two-dimensional coordinate system, and recycling institutions above the qualified rate baseline are marked as superior recycling institutions, and recycling institutions below the qualified rate baseline are marked as inferior recycling institutions;

[0101] It should be noted that in the description of step D2, it is assumed that there are 8 sulfur hexafluoride gas recovery agencies under the power grid, see Fig.14 , the 1st, 3rd, and 8th recycling mechanisms are marked as secondary recycling, and the 2nd, 4th, 5th, 6th, and 7th recycling mechanisms are marked as superior recycling.

[0102] From the above description, it can be seen that the method for analyzing the effectiveness of sulfur hexafluoride gas recovery and reuse provided by the present application can accurately describe the actual equilibrium state of the recovered sulfur hexafluoride gas, thereby achieving a relatively accurate preliminary prediction of its stability; then, based on the preliminary prediction information, the recovery rate of sulfur hexafluoride gas is processed by symbolic calibration, formula processing and secondary verification calculation; the recovery rate of sulfur hexafluoride gas is accurately output from different description levels, and the purity sampling pass rate of sulfur hexafluoride gas is accurately output by formula processing and substitution comparison, so as to comprehensively evaluate the recovery situation of each recovery agency and provide clear recovery reference data for each recovery agency, combined with statistical analysis of charts, which greatly promotes the improvement of the recovery process and results of each agency, and improves the efficiency and level of recovery and reuse of sulfur hexafluoride gas.

[0103] In one embodiment, see Figure 2 , the physical indicator data include: measured pressure, measured temperature and molar volume; the pressure error prediction signal includes a prediction accuracy signal and a prediction deviation signal; the pressure error prediction analysis is performed based on the physical indicator data of sulfur hexafluoride gas to obtain a pressure error prediction signal, including:

[0104] S201: Determine the density linear function according to the empirical coefficient and the gas constant of sulfur hexafluoride gas; see the description of the above step A1 for details;

[0105] S202: Determine the gas storage dynamic pressure value P based on the density linear function, the measured temperature and the molar volume i |; See the description of step A1 above for details;

[0106] S203: Determine the dynamic error value Hwc according to the measured pressure and the dynamic pressure value of the gas storage i ; See the description of step A2 above for details;

[0107] S204: Compare dynamic error value Hwc i The pressure error prediction signal is compared with the preset error threshold Yu1, and the pressure error prediction signal is determined to be a prediction accuracy signal or a prediction deviation signal according to the comparison result; see the description of the above step A2 for details.

[0108] It should be noted that the dynamic error value Hwc i The smaller the performance value, the more accurate the data collected and monitored by each recycling agency; conversely, the less accurate the data collected and monitored by each recycling agency.

[0109] It should also be noted that the formula Indicates the predicted dynamic pressure value P of sulfur hexafluoride gas i |With the measured pressure P i Make a difference and compare the difference result with the measured pressure Pi The absolute value of the ratio is output, and the obtained Hwc i , as error data for measuring the pressure state performance of sulfur hexafluoride gas, and the error reference value (also called error threshold) Yu1 is a reference for judging the dynamic error of pressure, and the setting of the error reference value Yu1 is obtained through a large amount of experimental data, and this application does not limit its specific value.

[0110] From the above description, it can be seen that the method for analyzing the effectiveness of sulfur hexafluoride gas recovery and reuse provided in the present application can perform pressure error prediction analysis based on the physical indicator data of sulfur hexafluoride gas to obtain a pressure error prediction signal.

[0111] In one embodiment, see Figure 3 , when the pressure error prediction signal is an accurate prediction signal; perform quantitative analysis of gas recovery based on physical indicator data, including:

[0112] S301: generating a recovery value according to a weight value before gas storage recovery and a weight value after gas storage recovery in the physical indicator data;

[0113] S302: Determine the recovery rate result value according to the recovery amount value.

[0114] It can be understood that in this embodiment, the pressure error prediction signal is a prediction accuracy signal; see the above step B1: when the prediction accuracy signal is received, the weight value before gas storage recovery and the weight value after gas storage recovery in the physical indicator data are retrieved and calibrated as M respectively. i and M i |, according to the formula Obtain the recovery value Hsl i , and the recovery value Hsl i As the recovery result value Zhs i Output.

[0115] From the above description, it can be seen that the method for analyzing the effectiveness of sulfur hexafluoride gas recovery and reuse provided in the present application can perform quantitative analysis of gas recovery based on physical indicator data.

[0116] In one embodiment, see Figure 4 , when the pressure error prediction signal is a prediction deviation signal; perform quantitative analysis of gas recovery based on physical index data and loss index data, including:

[0117] S401: Generate a loss value according to the weight loss value and the air pressure loss value in the loss index data; see the description of the above step B2 for details;

[0118] S402: Determine the comprehensive value according to the loss value and the historical recovery value; see the description of the above steps B3 and B4 for details;

[0119] S403: Generate a calculation efficacy signal according to the comprehensive value and the preset recovery rate threshold; see the description of the above step B4 for details;

[0120] S404: Determine the recovery rate result value based on the type of calculated efficacy signal; see the description of the above step B5 for details.

[0121] It can be understood that, in this embodiment, the pressure error prediction signal is a prediction accuracy signal; see the above steps B2 to B5 for details.

[0122] It should be noted that using the formula The recovery value Hsl i It can be used to indicate the gas recovery rate of sulfur hexafluoride gas during the recovery process.

[0123] Using the formula The loss value Sun i It can be used to indicate the gas loss rate of sulfur hexafluoride gas during the recovery process.

[0124] Using the formula The historical recovery mean Can be used to represent multiple recovery values ​​Hsl in the historical recovery judgment set i The average result of the historical recovery is As the reference result of the rated recovery rate, and through the formula Recover the historical mean and loss value Sun i Perform sum operation to obtain the comprehensive value G i , and the comprehensive value G i Subtract the absolute value from the unit coefficient 1, and introduce the preset threshold Yu2 as the formula |G i -1|, if it is within the range of the preset threshold value Yu2, then the formula |G i The result of -1| is almost close to 0, which fully demonstrates the accuracy of the secondary calculation results of sulfur hexafluoride and can further clarify the recovery situation of sulfur hexafluoride gas.

[0125] From the above description, it can be seen that the method for analyzing the effectiveness of sulfur hexafluoride gas recovery and reuse provided in the present application can perform quantitative analysis of gas recovery based on physical indicator data and loss indicator data.

[0126] In one embodiment, when the calculated effectiveness signal is a calculated valid signal; determining the recovery rate result value based on the type of the calculated effectiveness signal includes: determining the recovery rate result value according to the loss amount value.

[0127] Specifically, the difference between 1 and the loss value is determined as the recovery rate result value.

[0128] That is, when generating a computationally effective signal, according to the formula Hsl′=1-|Sun i |, and obtain the predicted recovery value Hsl′, and use it as the recovery rate result value Zhs i Output.

[0129] From the above description, it can be seen that the method for analyzing the effectiveness of sulfur hexafluoride gas recovery and reuse provided in the present application can determine the recovery rate result value based on the type of calculated effectiveness signal.

[0130] In one embodiment, see Figure 5 , when the calculation effectiveness signal is a calculation invalid signal; after generating the calculation effectiveness signal according to the comprehensive value and the preset recovery rate threshold, it also includes:

[0131] S501: Generate a repeat instruction (also called a quantitative error signal) according to a calculation invalid signal;

[0132] S502: Re-collecting physical index data and loss index data according to the repeated instruction until a calculation-valid signal is obtained.

[0133] It should be noted that the specific execution process of step S502 is equivalent to re-executing the process of the above steps B1 to B5.

[0134] From the above description, it can be seen that the method for analyzing the effectiveness of sulfur hexafluoride gas recovery and reuse provided in the present application can ultimately obtain a calculation effective signal.

[0135] In one embodiment, see Figure 6 , conduct purity sampling analysis based on the gas quality data of sulfur hexafluoride gas to obtain the sampling pass rate, including:

[0136] S601: Determine the impurity content according to the impurity component and the total component amount in the gas quality data; see the description of the above step C1 for details;

[0137] S602: Determine the sampling pass rate according to the pass threshold and the impurity content; see the description of step C2 above for details.

[0138] It should be noted that after purification, the sulfur hexafluoride gas needs to be sampled for impurity content, and the content of impurities such as air, carbon tetrafluoride, and carbon dioxide in the sample inspection results must be recorded in order to understand the sample inspection situation of sulfur hexafluoride gas purification.

[0139] It should also be noted that the preset threshold Yu3 is used to verify the impurity content zh i Whether the reference value is set to meet the recycling sampling requirements; in specific implementation, the impurity content can be seti If the value is within the range of the preset threshold value Yu3, the requirement is met; otherwise, the requirement is not met.

[0140] From the above description, it can be seen that the method for analyzing the effectiveness of sulfur hexafluoride gas recovery and reuse provided in the present application can perform purity sampling analysis based on the gas quality data of sulfur hexafluoride gas to obtain the sampling pass rate.

[0141] It should be noted that when implementing the method described in this application, a technician in this field can collect multiple groups of sample data and set a corresponding empirical coefficient for each group of sample data. The size of the coefficient is to quantify each parameter to obtain a specific value for subsequent comparison. The size of the empirical coefficient depends on the amount of sample data and the control of each group of sample data by the technician in this field; as long as it does not affect the proportional relationship between the parameter and the quantified value, this application is not limited to this.

[0142] It should be noted that, when the method described in the present application is specifically implemented, each sulfur hexafluoride gas recovery organization under the power grid can be taken as the object, and basic indicator data information and loss indicator data information related to the recovery and reuse of sulfur hexafluoride gas can be collected accordingly.
