The tilt angle is the angle between the upper surface of the designated outdoor power meter box measured by the automatic level when it is in a horizontal state and the upper surface of the designated outdoor power meter box.

[0037] The specific method for obtaining the wind speed and wind direction detected by each designated outdoor power meter box in the current time period is: using an anemometer to measure and obtain the wind speed and wind direction detected by each designated outdoor power meter box in the current time period.

[0039] The operating data of each test of each designated outdoor power meter box in the current time period includes metering accuracy, box installation firmness and exposed area of ​​each test surface.

[0040] It should be explained that the detection surfaces are a general term for the outer top surface, outer bottom surface and outer side surfaces of a designated outdoor power metering box.

[0041] It should be further explained that the specific method for obtaining the metering accuracy of each designated outdoor power meter box during the current time period is: directly reading the voltage, current and power factor of each designated outdoor power meter box during the current time period from each designated outdoor power meter box, and recording them as ,in , The numbers corresponding to the designated outdoor power meter boxes.

[0045] The internal operating environment analysis module is used to analyze and obtain the outdoor power metering boxes of various internal risk operating environments.

[0046] As a preferred feasibility example, in the analysis process of each internal risk operating environment outdoor power meter box, it is necessary to construct the internal operating environment compliance of each designated outdoor power meter box. The specific analysis method includes: extracting the temperature, humidity and various gas concentrations of the internal operating environment of each designated outdoor power meter box detected in the current time period, and recording them as ,in, , Analyze the internal operating environment compliance of each designated outdoor power meter box by assigning corresponding numbers to each type of gas ,in are the suitable temperature and humidity of the internal operating environment of the outdoor power meter box extracted from the cloud database, are the temperature fluctuation coefficient and humidity fluctuation coefficient of the internal operating environment of each designated outdoor power meter box in the current time period, and and , The first condition that does not affect the use of outdoor power meter box is allowed to exist Gas concentration.

[0047] As a preferred feasibility example, the specific acquisition method of each internal risk operating environment outdoor power meter box includes: comparing the internal operating environment compliance of each designated outdoor power meter box with the set internal operating environment compliance threshold; if the internal operating environment compliance of a designated outdoor power meter box is less than the set internal operating environment compliance threshold, then the designated outdoor power meter box is recorded as an outdoor power meter box in an internal risk operating environment; otherwise, the designated outdoor power meter box is recorded as an outdoor power meter box in an internal safe operating environment, thereby obtaining the outdoor power meter boxes in each internal risk operating environment.

[0048] The external operating environment analysis module is used to analyze and obtain the outdoor power metering boxes of various external risk operating environments.

[0049] The external operating environment analysis module includes an operating environment compliance analysis unit, a correlation coefficient analysis unit and an external operating environment analysis unit.

[0050] The operating environment compliance analysis unit is used to analyze the compliance of the external operating environment of each designated outdoor power meter box, namely, the first, second and third categories.

[0051] As a preferred feasibility example, the specific analysis method of the Class I, Class II and Class III compliance of the external operating environment of each designated outdoor power meter box includes: extracting the electromagnetic intensity of each detection of each designated outdoor power meter box in the current time period , analyze the compliance of the external operating environment of each designated outdoor power meter box , ,in The suitable electromagnetic intensity of the external operating environment of the outdoor power meter box is extracted from the cloud database.

[0052] Extract the vibration amplitude, tilt angle and wind speed of each designated outdoor power meter box detected in the current time period and record them as , analyze the Class II compliance of the external operating environment of each designated outdoor power meter box ,in They are respectively the allowable vibration amplitude, allowable tilt angle and allowable wind speed under the conditions that do not affect the use of the outdoor power meter box.

[0053] Specifically, the allowable vibration amplitude that does not affect the use of the outdoor power meter box includes but is not limited to 1 cm per second.

[0054] It should be explained that the outdoor power meter box contains precise metering equipment and electronic components. Excessive vibration may cause damage to the equipment or reduce the measurement accuracy. Setting a lower vibration amplitude limit can ensure that the equipment is not affected by vibration during normal operation. Therefore, the permissible vibration amplitude under the conditions that do not affect the use of the outdoor power meter box is set to 1 cm per second.

[0055] The allowable tilt angle that does not affect the use of the outdoor power meter box includes but is not limited to 15 degrees.

[0056] It should be explained that the design of outdoor power meter boxes usually takes into account their stability under different installation conditions. The limit of the tilt angle is to prevent the equipment from tilting due to improper installation or external environmental factors such as foundation settlement, thereby avoiding equipment damage or measurement errors. Setting a smaller tilt angle limit can ensure that the equipment is not affected by the tilt angle during normal operation. Therefore, the allowable tilt angle under the conditions that do not affect the use of the outdoor power meter box is set to 15 degrees.

[0057] The allowable wind speed under the conditions that do not affect the use of the outdoor power meter box includes but is not limited to 3.3 meters per second.

[0058] It should be explained that outdoor power meter boxes need to have a certain wind resistance to ensure that they can still work normally under severe weather conditions. The wind speed limit is based on a comprehensive consideration of factors such as the equipment's wind resistance design, material strength, and structural stability, and is intended to ensure that the equipment can be used safely under most climatic conditions. Setting a smaller wind speed limit can ensure that the equipment is not affected by wind speed during normal operation. Therefore, the permissible wind speed under conditions that do not affect the use of outdoor power meter boxes is set to 3.3 meters per second.

[0060] Specifically, the set permissible rainfall under the conditions that do not affect the use of the outdoor power meter box includes but is not limited to rainfall not exceeding 4.9 mm within 12 hours.

[0061] It should be explained that outdoor power meter boxes usually have a certain waterproof design to ensure that they can still work normally in rainy weather. The setting of the permissible rainfall is determined based on the waterproof level and sealing performance of the equipment. The rainfall of no more than 4.9 mm in 12 hours is the maximum value in the rainfall range of light rain, which is recorded as the permissible rainfall under the conditions that do not affect the use of the outdoor power meter box to ensure that rainwater will not penetrate into the equipment and cause damage under the condition that the rainfall does not exceed this amount.

[0062] The allowable snowfall under the conditions that do not affect the use of the outdoor electricity meter box includes but is not limited to a 24-hour snowfall not exceeding 2.4 mm.

[0063] It should be explained that, in addition to directly imposing snow load on the equipment, snowfall may also cause risks such as corrosion or short circuit to the equipment due to the ice-water mixture formed after the snow melts. The maximum value of the snowfall range for light snow is the 24-hour snowfall of no more than 2.4 mm, which is recorded as the permissible snowfall under the conditions that do not affect the use of the outdoor power meter box, to ensure that under the condition of not exceeding the snowfall, the snow load and the ice water from the snow melt will not cause damage to the equipment.

[0064] The present invention obtains the external operating environment data of each designated outdoor power meter box for each detection, analyzes the compliance of the external operating environment of each designated outdoor power meter box with Class I, Class II and Class III, helps to timely discover the abnormal conditions of the external operating environment of each designated outdoor power meter box, ensures the safety and stability of each designated outdoor power meter box, reduces the risk of failure and damage thereof, and thus improves the economic benefits of the power company.

[0065] The correlation coefficient analysis unit is used to analyze the correlation coefficient between the external operating environment data and the operating data of each designated outdoor power meter box.

[0066] As a preferred feasibility example, the correlation coefficient between the external operating environment data and the operating data of each designated outdoor power meter box, and its specific analysis method also includes: extracting the metering accuracy of each detection of each designated outdoor power meter box in the current time period, extracting the electromagnetic strength of each detection of each designated outdoor power meter box in the current time period, and calculating according to the calculation formula of the Pearson correlation coefficient to obtain the correlation coefficient between the electromagnetic strength and the metering accuracy of each designated outdoor power meter box.

[0067] It should be further explained that the Pearson correlation coefficient is a coefficient used to measure the degree of correlation between two continuous variables. Its value range is [ − 1 , 1 ] , where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no linear correlation. According to the calculation formula of the Pearson correlation coefficient γ = ∑ q = 1 Q [ ( x q − x ¯ ) * ( y q − y ¯ ) ] ∑ q = 1 Q ( x q − x ¯ ) 2 * ∑ q = 1 Q ( y q − y ¯ ) 2 Pearson correlation coefficient can be obtained ,in The first Observations, are the observed means of two continuous variables, , is the number of each observation.

[0068] Specifically, the measurement accuracy of each designated outdoor power meter box detected in the current time period and the electromagnetic intensity of each designated outdoor power meter box detected in the current time period are substituted into the calculation formula of the Pearson correlation coefficient to obtain the correlation coefficient between the external operating environment data and the operating data of each designated outdoor power meter box. ,Right now ACC i = ∑ j = 1 b [ ( Es ij − 1 b ∑ j = 1 b Es ij ) * ( acc ij − 1 b ∑ j = 1 b acc ij ) ] ∑ j = 1 b ( Es ij − 1 b ∑ j = 1 b Es ij ) 2 * ∑ j = 1 b ( acc ij − 1 b ∑ j = 1 b acc ij ) 2 .

[0069] The installation firmness of each designated outdoor power meter box tested in the current time period and the vibration amplitude, tilt angle and wind speed of each designated outdoor power meter box tested in the current time period are extracted. Similarly, the correlation coefficient between the vibration amplitude of each designated outdoor power meter box and the installation firmness of the box, the correlation coefficient between the tilt angle and the installation firmness of the box, and the correlation coefficient between the wind speed and the installation firmness of the box can be obtained.

[0070] The exposed area of ​​each detection surface of each designated outdoor power meter box in the current time period and the wind direction, rainfall and snowfall of each detection of each designated outdoor power meter box in the current time period are extracted. Similarly, the correlation coefficient between the wind direction of each designated outdoor power meter box and the exposed area of ​​each detection surface, the correlation coefficient between the rainfall and the exposed area of ​​each detection surface, and the correlation coefficient between the snowfall and the exposed area of ​​each detection surface can be obtained.

[0071] The present invention analyzes the correlation coefficient between the external operating environment data and the operating data of each designated outdoor power meter box according to the external operating environment data and the operating data detected by each designated outdoor power meter box, which helps to identify the influence of each parameter in the external operating environment data of each designated outdoor power meter box on each parameter of its operating data, and helps power companies to take targeted measures to optimize the external operating environment data, thereby improving the operating status of each designated outdoor power meter box, thereby extending its service life and reducing maintenance costs.

[0075] Specifically, the set external operating environment type compliance threshold includes but is not limited to ,in Specifies the number of outdoor power meter box inspections within the current time period.

[0076] It should be explained that the compliance of the external operating environment of each designated outdoor power meter box is based on the formula It is calculated that the outdoor power meter box is an important device in the power system.

Therefore, and The maximum threshold of each is set to 1, and the compliance threshold of the external operating environment can be set to .

[0078] It should be explained that the range of the correlation coefficient between electromagnetic intensity and measurement accuracy is [ − 1 , 1 ] , where 1 indicates a completely positive correlation, -1 indicates a completely negative correlation, and 0 indicates no linear correlation. Therefore, setting the threshold of the correlation coefficient between electromagnetic intensity and measurement accuracy to 0.3 can effectively evaluate the impact of electromagnetic interference on measurement accuracy and take corresponding protective measures to reduce interference.

Therefore, and The maximum threshold of the external operating environment is set to 1, and the second type of compliance threshold of the external operating environment can be set to .

[0082] The set threshold values ​​of correlation coefficient between vibration amplitude and cabinet installation firmness, correlation coefficient between tilt angle and cabinet installation firmness, and correlation coefficient between wind speed and cabinet installation firmness include but are not limited to 0.3.

[0083] It should be explained that the value ranges of the correlation coefficient thresholds between vibration amplitude and box installation firmness, the correlation coefficient thresholds between tilt angle and box installation firmness, and the correlation coefficient thresholds between wind speed and box installation firmness are [ − 1 , 1 ] , where 1 indicates a completely positive correlation, -1 indicates a completely negative correlation, and 0 indicates no linear correlation. Therefore, by setting the correlation coefficient threshold between the vibration amplitude and the cabinet installation firmness, the correlation coefficient threshold between the tilt angle and the cabinet installation firmness, and the correlation coefficient threshold between the wind speed and the cabinet installation firmness to 0.3, the influence of the vibration amplitude, tilt angle, and wind speed on the cabinet installation firmness can be effectively evaluated, and corresponding protective measures can be taken to reduce interference.
