[0054] The present application is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present application and implement it.

[0055] Embodiment 1:

[0056] Please refer to Figure 1 As shown in the figure, a remote monitoring method for resonance fracture of a grading ring is used. Taking a grading ring of a substation as an example, the operating status of the grading ring is comprehensively evaluated by collecting and analyzing vibration data, meteorological data, etc. The steps include:

[0057] S101 remotely collects the first vibration data of the ring body and the lower supporting rigid component of the pressure equalizing ring.

[0058] A large substation somewhere was selected, which was equipped with a grading ring. The grading ring is an important component in the substation for balancing voltage distribution and preventing insulation flashover. It is usually made of metal, in the shape of a ring or a combination of multiple rings, and installed at a high place in the substation, such as above or near the transformer.

[0059] In order to accurately monitor the vibration of the pressure equalizing ring, a stable position directly below the pressure equalizing ring is selected as a vibration monitoring point. For example, a flat position without any obstructions is selected on the ground, and a fixed bracket is installed there for installing the vibration monitoring equipment.

[0060] A microwave interferometry system is used to capture the vibrations of the pressure equalizing ring and its support.

[0061] First, select a point on the edge of the voltage-grading ring that is easy to capture and install a microwave reflector there. Similarly, select a point on the edge of the rigid support of the voltage-grading ring (such as a post insulator) and install another microwave reflector. These two reflectors will be used to reflect microwave signals to obtain vibration data.

[0062] After the preparations are completed, the microwave interferometry system starts working. The microwave interferometry system first emits a high-frequency, continuous radar wave of 200 Hz. These radar waves will be irradiated onto the microwave reflectors on the pressure equalizing ring and the support respectively, and generate echoes. The system receives these echoes and uses linear frequency modulation continuous wave technology and interferometry technology to perform interferometric measurement on the echoes. By calculating and analyzing these interference data, the system accurately obtains the first vibration data of the pressure equalizing ring and the support respectively.

[0063] For example, if the pressure-equalizing ring vibrates slightly due to the wind, these vibrations will cause the microwave reflector to shift slightly. These shifts will change the phase and frequency of the reflected radar waves, which will be captured by the microwave interferometry system.

[0064] S102 monitors the wind direction and wind speed in the environment where the pressure equalizing ring is located.

[0065] During the vibration monitoring of the equalizing ring, understand and record the surrounding meteorological conditions.

[0066] Choose a mini weather station suitable for outdoor use. The weather station should have the basic functions of measuring wind direction and wind speed, and can also record data in real time. For example, choose a portable, high-precision, windproof and waterproof weather station that can withstand electromagnetic interference and extreme weather conditions in the substation environment.

[0067] Place the selected micro-meteorological station at a suitable location near the pressure equalizing ring. This location should be as close to the pressure equalizing ring as possible to ensure that the measured meteorological data can accurately reflect the environmental conditions of the pressure equalizing ring.

[0068] After the weather station is set up, set the meteorological parameters to be monitored, including wind direction and wind speed. These parameters are measured in real time through the sensors built into the weather station.

[0069] Once the monitoring parameters are set and the sensors are calibrated, the weather station starts recording data in real time, including meteorological parameters such as wind direction and speed, as well as information such as timestamps.

[0070] S103 establishes a fitting curve according to the wind direction-wind speed and the first vibration data.

[0071] The vibration frequency of the grading ring of a substation was monitored over a period of time, and the wind speed and wind direction data were recorded at the same time. These data were organized into a table containing fields such as timestamp, grading ring vibration frequency, wind speed and wind direction.

[0072] Next, use data analysis software, such as Excel or professional data analysis software, to process these data.

[0073] First, filter out the vibration frequency data of the pressure equalizing ring and the support, and correspond to their wind speed data. Then, use the scatter plot function in the software to represent these data points on a coordinate graph, where the X-axis represents the wind speed and the Y-axis represents the vibration frequency.

[0074] Based on the scatter plot, the trend line function in the software is used to fit the data points and establish a functional relationship curve between wind speed and vibration frequency. Since the vibration frequency is affected by many factors, try different fitting functions (such as linear, quadratic, logarithmic, etc.) and select the fitting function that best fits the actual data.

[0075] S104 determines, based on the fitting curve, a first meteorological factor causing resonance between the ring body of the equalizing ring and the lower supporting rigid component.

[0076] After obtaining the wind speed-vibration frequency relationship curves, further analyze these curves and pay attention to the peak points on the curves. These points usually indicate that at a specific wind speed, the vibration frequency of the pressure equalizing ring or support reaches the maximum value, that is, resonance occurs.

[0077] In order to determine the meteorological factors of resonance, the wind direction data is combined for analysis. This is because changes in wind direction will affect the direction and magnitude of the wind's force on the equalizing ring, thereby affecting the occurrence of resonance. The wind speed and wind direction data are combined to draw a three-dimensional surface graph or scatter plot of wind speed-wind direction-vibration frequency to more fully understand the meteorological factors of resonance.

[0078] By analyzing these graphs, it is possible to determine under which wind speed and direction conditions the grading ring or support is most likely to resonate. These meteorological factors will be the first meteorological factors in the subsequent analysis.

[0079] S105 compares the first meteorological factor with the second meteorological factor of the environment throughout the year, and determines the resonance fracture risk of the equalizing ring according to the ratio of the first meteorological factor to the second meteorological factor.

[0080] After determining the first meteorological factors that cause resonance in the grading ring or support, compare these first meteorological factors with the second meteorological factors of the grading ring operating environment throughout the year. Plot these meteorological data into a bar graph or a line graph for comparison with the resonant wind speed range. If the meteorological conditions at the location of the substation are within the resonant wind speed range for most of the year, then it is determined that the grading ring or support is prone to resonance fracture.

[0081] Furthermore, in order to more accurately evaluate the safety of the pressure equalizing ring, a probability statistical method is also used to calculate the frequency and duration of the resonant wind speed range in the annual meteorological data. If these data exceed a certain threshold (such as a frequency of more than 50%, a duration of more than a certain number of hours), then appropriate measures are taken to reduce the risk of resonance fracture, such as strengthening the pressure equalizing ring structure, changing the support design or adding dampers.

[0082] like Figure 3 The present application also provides a remote monitoring device for resonance fracture of a grading ring, comprising:

[0083] The acquisition module 201 is used to remotely acquire first vibration data of the ring body and the lower supporting rigid component of the pressure equalizing ring;

[0086] A factor module 204 is used to determine a first meteorological factor causing resonance between the ring body of the equalizing ring and the lower supporting rigid component according to the fitting curve;

[0087] The judgment module 205 is used to judge the resonance fracture risk of the grading ring by comparing the first meteorological factor with the second meteorological factor of the whole year in the environment and judging the proportion of the first meteorological factor to the second meteorological factor.

[0088] like Figure 5 As shown, the present application also provides a remote monitoring device for resonance fracture of a grading ring, comprising:

[0089] The memory 301 is used to store a computer executable program of the method for remote monitoring resonance fracture of an equalizing ring described in the first item above;

[0091] Embodiment 2:

[0092] like Figure 2As shown, based on Example 1, Example 2 of the present application can also perform the following operations based on the operating environment of the first meteorological factor.

[0093] S106: Based on the first meteorological factor condition, compare the difference between the vibration data of the grading ring body and the lower supporting rigid component of the grading ring on the three-phase line of the power system and the first vibration data.

[0094] After determining the operating environment status, the vibration frequency of the A, B, and C three-phase grading rings of the power grid is monitored.

[0095] After the monitoring data is obtained, it is compared with the first vibration data obtained in Example 1. For example, in the vibration data, the vibration frequencies of phases A and C are within the normal range, while the vibration frequency of phase B is slightly higher (exceeding a deviation of 2 Hz).

[0096] S107: If the difference value is greater than a preset threshold, it is determined that the operating state of the pressure equalizing ring is unstable.

[0097] According to the judgment standard (ie the frequency deviation does not exceed 10%), the operation of the A-phase and C-phase grading rings is stable, while the vibration frequency deviation of the B-phase grading ring is large and unstable.

[0098] In response to the instability of the B-phase equalizing ring, follow-up treatment and reinforcement were carried out. This included adding dampers, adjusting the support structure of the equalizing ring, and strengthening its wind resistance. At the same time, the vibration of the B-phase equalizing ring was continuously monitored to ensure its stable operation.
