Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pressure equalizing rings, and in particular to an adaptive wind-resistant pressure equalizing ring and an intelligent control method for high wind load areas. Background Art
[0002] With the widespread application of ultra-high voltage and UHV transmission technologies, most ultra-high voltage power grid equipment is equipped with grading rings to improve the electric field distribution of power equipment, thereby helping to reduce the unevenness of the electric field and suppress the occurrence of discharge. The basic working principle of the grading ring is to use the electric field distribution effect of the conductor to expand the more concentrated electric field around the insulator and switch to the outside, making the distribution of the surrounding electric field more uniform, thereby preventing the occurrence of high-voltage system problems such as corona and flashover.
[0003] At present, my country uses grading rings in power transmission and transformation projects of 110kV and above, and adopts a fixed design, relying on structural stiffness to resist wind loads. However, with the change of wind speed and direction, the grading ring will be subjected to wind impacts from different directions, especially in high wind load areas, where it is difficult to cope with complex and changeable wind load environments. The lack of local stiffness of the grading ring structure will cause the equipment to resonate under wind impact. Long-term exposure to vibration environment will gradually accumulate fatigue in the connection parts and materials of the grading ring, which may eventually cause the ring body to crack, damage or even fail, thus affecting the safe and stable operation of the equipment.
[0004] At present, relevant pressure equalizing ring technology inventions are usually designed and developed from the aspects of structural form, test adjustment and intelligent identification control.
[0005] (1) Structural form For example, patent documents such as application number 202310247617.2 adopt a detachable equalizing ring structure, a detachable arc-shaped supplementary rod is installed at the gap of the gap ring, and a clamping structure is installed on the inner wall of the arc-shaped supplementary rod to clamp and fix the detachable equalizing ring; for example, patent documents such as application number 202311693272.X design a rotating equalizing ring, which drives the gear to rotate through a motor, so that a rotating protective barrier is formed on the upper part of the equalizing ring body, but the wind resistance stability of a single equalizing ring in an ultra-high voltage transmission line is general. For example, patent documents such as application numbers 201610998321.4, 202221913250.0, and 202311018153.4 all adopt a double-layer equalizing ring structure, and invent and innovate the equalizing ring from the aspects of retractable length, safety and stability, and flexible and easy adjustment, respectively, indicating that the double-layer equalizing ring has a certain structural stability and stronger wind resistance.
[0006] (2) Experimental adjustment For example, the patent document with application number 201810171693.9 invented a special test grading ring that can be adjusted with the grading radius. It adopts a spring hook design, and can fix the special test grading ring to the operating grading ring through the hook during the high-voltage electrical field test, thereby improving the work efficiency of the high-voltage electrical test. The patent document with application number 201810171693.9 designs an adjustable test grading ring, which is mainly based on an adjustable loading bracket as the core device, and can adapt to test grading rings of different sizes, and cooperate with an adjustable clamping tool to fix the casing, so as to carry out related test operations.
[0007] (3) Intelligent identification control For example, patent document No. 201810171693.9 proposes a defect detection method for equalizing rings based on drones and computer vision models, using an image processing method with a rectangular frame and four-point annotations for the equalizing ring area to improve the speed of identifying defects during model prediction. For example, patent documents No. 201810171693.9 and 202111499025.7 design different types of equalizing rings from the perspective of intelligent control of bird repellent. The former drives the hammer device through the rotation of the equalizing ring and strikes the soundboard to create sound to drive away birds. The latter achieves the purpose of bird repellent and cleaning above the equalizing ring by setting a bird repellent component and a cleaning brush on the side of the shaft, and the shaft drives the bird repellent component and the cleaning brush to rotate.
[0008] The following technical defects exist in the current field: (1) Insufficient adaptability: Existing grading ring designs are mostly focused on detachable and rotatable structures. The grading ring is mainly fixed on the insulator, which fails to effectively cope with the dynamic changes of high wind loads, which may cause it to perform poorly under extreme climate conditions. The double-layer grading ring structure used in most patent documents, although it provides a certain degree of stability, still lacks versatility and flexibility and cannot adapt to the needs of different scenarios, especially in ultra-high voltage transmission lines, where its applicability is limited.
[0009] (2) Lack of intelligent feedback mechanism: Most of the current intelligent control is passive response rather than active adjustment, which may lead to failure to respond in time when the wind load changes, and fail to effectively ensure the stability and safety of the equalizing ring. The existing intelligent control design mainly focuses on defect detection and bird repelling functions, such as application number 201810171693.9, etc., lacking real-time monitoring and response measures for wind loads. This single function limits its application in high wind load areas and cannot form a comprehensive protection system.
[0010] In summary, the currently disclosed patents for equalizing rings have obvious deficiencies in terms of structural adaptability, adjustment flexibility, and intelligent control functions. These defects limit their effectiveness and application potential in high wind load areas. Therefore, the development of an adaptive wind-resistant equalizing ring and intelligent control method for high wind load areas can not only solve the deficiencies of the prior art, but also provide a more effective solution for the safe and stable operation of high-voltage electrical equipment. The present invention relates to the field of equalizing ring technology, and in particular, to an adaptive wind-resistant equalizing ring and intelligent control method for high wind load areas. Summary of the invention
[0011] In view of the shortcomings of the prior art, the present invention provides an adaptive wind-resistant equalizing ring and intelligent control method suitable for high wind load areas.

The control algorithm module includes a wind load model and a wind resistance strategy. The force distribution of the wind load on the pressure equalizing ring is calculated through the wind load model, and the optimal angle of the pressure equalizing ring to rotate to the side with strong stiffness is determined. The communication module is used for data exchange between the core control module and the operating host. The early warning device is connected to the core control module, and includes an audible and visual alarm and a remote alarm system. When the core control module detects that the wind speed or the stress of the pressure equalizing ring exceeds a preset safety range, the audible and visual alarm sounds an alarm, and the remote alarm system sends the alarm information to the operating host.
[0013] In the above structure: the invention proposes an adaptive wind-resistant equalizing ring for high wind load areas, comprising an equalizing ring, a support rod, a conductive rubber pad, a connector, an electric spindle rotating device, a core control module, a wind speed and direction sensor, and an early warning device. Among them, the pressure equalizing ring includes a first pressure equalizing ring and a second pressure equalizing ring. The first pressure equalizing ring is located above the second pressure equalizing ring to form an upper and lower double-layer pressure equalizing ring structure to enhance the overall stability. Connectors and micro wireless stress sensors are respectively installed on the first pressure equalizing ring and the second pressure equalizing ring. The micro wireless stress sensor is used to detect the stress of the two pressure equalizing rings and send it to the core control module in real time. The connector is used to realize the connection and fixation of the electric spindle rotation device.
[0014] The first pressure-equalizing ring and the second pressure-equalizing ring are connected by four equidistantly distributed vertical support rods to ensure the structural strength and wind resistance.
[0015] One end of the support rod is connected to the connector on the first voltage-equalizing ring, and the other end is connected to the connector of the second voltage-equalizing ring. Conductive rubber pads are installed at the connection between the support rod and the connector. The conductive rubber pads have certain plasticity and conductivity and can achieve certain buffering and conductive functions at the connection. The support rod is welded to the connector to ensure the reliability of electrical performance and mechanical connection.
[0016] The conductive rubber pad is made of highly conductive rubber material, which is embedded with highly conductive metal particles to ensure good conductivity. The thickness and hardness of the conductive rubber pad are precisely designed to provide appropriate buffering under wind loads while maintaining the electrical connection stability of the two equalizing rings. The conductive rubber pad is tightly combined with the support rod and the equalizing ring through silicone adhesive to avoid loosening and falling off under long-term wind loads, providing high-strength electrical connections and flexible connections, so that the system can remain stable under wind loads without electrical connection failures.
[0017] The wind speed and direction sensor can monitor the changes in wind speed and direction in the environment in real time, and transmit the data to the core control module, providing a basis for the angle adjustment of the pressure equalizing ring. The sensor selected in this application has ultrasonic measurement technology and has the characteristics of high precision, low power consumption and strong anti-interference ability.
[0018] The electric spindle rotating device is installed between the first equalizing ring and the second equalizing ring and its two ends are respectively connected and fixed to the connecting parts on the two. The electric spindle rotating device is used to realize the angle adjustment of the two equalizing rings. The electric spindle rotating device can adjust the angle of the two equalizing rings according to the signals provided by the wind speed and direction sensor and the core control module, so that the angles of the two equalizing rings can be rotated to the side with strong stiffness when the wind is strong, thereby improving the wind resistance. It includes a driving motor, a reducer and a rotating mechanism. The rated power and speed of the driving motor are determined according to the weight and wind load requirements of the equalizing ring. The reducer is used to convert the high-speed rotation of the motor into precise angle adjustment of the equalizing ring. The angle adjustment range of the rotating mechanism is generally set to ±45°. In actual applications, the rotation angle can be prevented from exceeding the predetermined range by installing a limit device.
[0019] The core control module is the intelligent control center of the present application, which can process real-time wind load data received from wind speed and direction sensors, micro wireless stress sensors and other devices. The core control module controls the electric spindle rotation device to rotate the two equalizing rings according to the changes in wind force to adapt to the incoming wind from different directions. The core control module integrates a data processing unit, a control algorithm module and a communication module. The data processing unit is used to receive and process data from wind speed and direction sensors and stress sensors, and calculate the optimal adjustment angle of the equalizing ring according to the set control algorithm. The control algorithm module includes a wind load model and a wind resistance strategy. The wind load model is used to calculate the force distribution of the wind load on the equalizing ring, and determine the optimal angle for the equalizing ring to rotate to the side with strong stiffness. The communication module is used for data exchange between the core control module and the operating host. The operating host can monitor the status of the equalizing ring in real time through the human-machine interface, and perform remote control and fault diagnosis.
[0020] The early warning device is used to alarm and send alarm signals, including an audible and visual alarm and a remote alarm system. When the core control module detects that the wind speed or the stress of the pressure equalizing ring exceeds the preset safety range, the early warning device is activated. The audible and visual alarm prompts the on-site staff to pay attention through flashing lights and buzzers, and the remote alarm system sends the alarm information to the operating host to ensure that emergency measures are taken in time under extreme wind load conditions.
[0021] As a preferred technical solution of the present invention: the thickness of the first pressure equalizing ring is greater than the thickness of the second pressure equalizing ring.
[0022] In the above structure: the thickness ratio of the first pressure equalizing ring and the second pressure equalizing ring is determined by the wind load requirement in a specific application. The first pressure equalizing ring is slightly thicker than the second pressure equalizing ring so as to have better anti-twisting performance under wind load.
[0023] As a preferred technical solution of the present invention: the first pressure equalizing ring, the second pressure equalizing ring and the support rod are all made of aluminum alloy, and the surfaces are electroplated with a corrosion-resistant layer.
[0024] In the above structure: the first equalizing ring, the second equalizing ring and the support rod are made of aluminum alloy material and are electroplated with a corrosion-resistant layer on their surfaces, so that they have good corrosion resistance, wind resistance and electrical conductivity.
[0025] As a preferred technical solution of the present invention: the connecting part includes a connecting rod and a voltage equalizing ring terminal, one end of the connecting rod is connected to the voltage equalizing ring terminal, and the other end is connected to the first voltage equalizing ring or the second voltage equalizing ring, and the two ends of the rotating mechanism are respectively connected to the voltage equalizing terminal on the first voltage equalizing ring and the voltage equalizing terminal on the second voltage equalizing ring.
[0026] In the above structure: one end of the connecting rod is connected to the voltage equalizing ring terminal, and the other end is connected to the first voltage equalizing ring or the second voltage equalizing ring, so as to realize the installation and fixation of the connecting piece on the first voltage equalizing ring or the second voltage equalizing ring and the fixation of the voltage equalizing ring terminal thereon. The two ends of the rotating mechanism are respectively connected to the voltage equalizing terminal on the first voltage equalizing ring and the voltage equalizing terminal on the second voltage equalizing ring, so as to facilitate the rotation of the first voltage equalizing ring and the second voltage equalizing ring by adjusting the driving motor.

[0028] In the above structure: the housing is used to protect the electric spindle rotating device.
[0029] As a preferred technical solution of the present invention: it also includes a fixing rod and a connector, the fixing rod is connected and fixed by the connector, the bottom of the fixing rod is fixed to the ground by a fixing seat, and the bottom of the second pressure equalizing ring is fixed to the top of the fixing rod.
[0030] In the above structure: one end of the fixing rod is fixed on the ground, and multiple fixing rods are connected above it through a connector. This connection method can control the installation height of the adaptive wind-resistant pressure-equalizing ring installed on the top of the fixing rod.
[0031] An intelligent control method for an adaptive wind-resistant pressure-equalizing ring in a high wind load area, characterized in that it comprises the following steps: S1. Real-time monitoring and data processing After the adaptive wind-resistant equalizing ring is installed and used, the wind speed and direction sensor continuously monitors the changes in wind speed and direction in the environment, and transmits the data to the core control module in real time. The core control module processes the received wind speed and direction data, generates a wind load model, and determines the intensity and direction of the current wind load. In particular, when a sudden increase in wind speed is detected, the core control module will start the early warning device to enter the early warning mode to determine whether to start the adjustment of the equalizing ring; S2. Wind load intensity and adjustment judgment If the incoming wind direction is on the weak side of the equalizing ring, the core control module calculates whether the structural stress of the equalizing ring reaches the stress threshold. If it is close to 60% of the threshold, an adjustment command is issued to start the electric spindle rotation device. If the structural stress of the equalizing ring is close to the set threshold, the core control module issues an adjustment command. According to the wind speed and wind direction data, the core control module calculates the best adjustment angle and rotates the equalizing ring to the strong side. S3. Continuous monitoring and adjustment After the pressure equalizing ring is adjusted, the system continues to monitor the wind speed, wind direction and stress state in real time to ensure that the pressure equalizing ring is always in the best wind resistance state. The core control module evaluates the stability of the pressure equalizing ring based on the latest monitoring data and adjusts the position of the pressure equalizing ring again if necessary. S4, pressure equalizing ring angle adjustment The core control module sets the maximum stress safety threshold and the maximum wind speed safety threshold. Once the wind speed or the stress of the equalizing ring is detected to exceed the maximum stress safety threshold range and the maximum wind speed safety threshold range, an alarm is immediately triggered. When the alarm is triggered, emergency protection measures are initiated.

[0033] As a preferred technical solution of the present invention: in step S4, the maximum stress safety threshold is set to 80% of the stress exceeding the limit, and the maximum wind speed safety threshold is set to a wind speed exceeding 30 m / s.
[0034] As a preferred technical solution of the present invention: in step S4, the emergency protection measures include locking the angle of the pressure equalizing ring or starting the bypass support mechanism.
[0035] Through the above structural design and intelligent control method, the present invention can effectively cope with extreme weather conditions in high wind load areas. The design of the equalizing ring with a double-layer structure enhances the overall stability and wind resistance. The combination of the core control module and the wind speed and direction sensor realizes the real-time intelligent adjustment of the angle of the equalizing ring, improving the wind resistance of the system. At the same time, the design of the early warning device can timely feedback extreme wind load information, providing reliable safety protection for maintenance personnel.

[0055] The early warning device is used to alarm and send alarm signals, and includes an audible and visual alarm and a remote alarm system. When the core control module detects that the wind speed or the stress of the equalizing ring exceeds the preset safety range, the early warning device is activated. The audible and visual alarm prompts the on-site staff to pay attention through flashing lights and buzzers, and the remote alarm system sends the alarm information to the operating host 13 to ensure that emergency measures are taken in time under extreme wind load conditions.
[0056] The thickness ratio of the first pressure equalizing ring 1 and the second pressure equalizing ring 3 is determined by the wind load requirement in a specific application. The first pressure equalizing ring 1 is slightly thicker than the second pressure equalizing ring 3 so as to have better anti-twisting performance under wind load.
[0057] The first balancing ring 1, the second balancing ring 3 and the support rod 2 are made of aluminum alloy material and are electroplated with a corrosion-resistant layer on their surfaces, so that they have good corrosion resistance, wind resistance and electrical conductivity.
[0058] One end of the connecting rod 6 is connected to the voltage equalizing ring terminal, and the other end is connected to the first voltage equalizing ring 1 or the second voltage equalizing ring 3, so as to realize the installation and fixation of the connecting piece 9 on the first voltage equalizing ring 1 or the second voltage equalizing ring 3 and the fixation of the voltage equalizing ring terminal thereon. The two ends of the rotating mechanism are respectively connected to the voltage equalizing terminal on the first voltage equalizing ring 1 and the voltage equalizing terminal on the second voltage equalizing ring 3, so as to facilitate the rotation of the first voltage equalizing ring 1 and the second voltage equalizing ring 3 by driving the motor.
[0059] The housing 7 is used to protect the electric spindle rotating device 8 .
[0060] One end of the fixing rod 11 is fixed on the ground, and a plurality of fixing rods 11 are connected to the top through a connector 10. This connection method can control the installation height of the adaptive wind-resistant pressure-equalizing ring installed on the top of the fixing rod 11.
[0061] like Figure 4 As shown, the present invention proposes an intelligent control method for an adaptive anti-wind equalizing ring in a high wind load area, comprising the following steps: S1. Real-time monitoring and data processing After the adaptive wind-resistant equalizing ring is installed and used, the wind speed and direction sensor 4 continuously monitors the changes in wind speed and direction in the environment, and transmits the data to the core control module in real time. The core control module processes the received wind speed and direction data, generates a wind load model, and determines the intensity and direction of the current wind load. In particular, when a sudden increase in wind speed is detected, the core control module will start the early warning device to enter the early warning mode to determine whether to start the adjustment of the equalizing ring; S2. Wind load intensity and adjustment judgment If the incoming wind 12 is located on the weak side of the equalizing ring, the core control module calculates whether the structural stress of the equalizing ring reaches the stress threshold. If it is close to 60% of the threshold, an adjustment command is issued to prepare to start the electric spindle rotation device 8. If the structural stress of the equalizing ring is close to the set threshold, the core control module issues an adjustment command. According to the wind speed and wind direction data, the core control module calculates the best adjustment angle and rotates the equalizing ring to the strong side. S3. Continuous monitoring and adjustment After the pressure equalizing ring is adjusted, the system continues to monitor the wind speed, wind direction and stress state in real time to ensure that the pressure equalizing ring is always in the best wind resistance state. The core control module evaluates the stability of the pressure equalizing ring based on the latest monitoring data and adjusts the position of the pressure equalizing ring again if necessary. S4, pressure equalizing ring angle adjustment The core control module sets the maximum stress safety threshold and the maximum wind speed safety threshold. Once the wind speed or the stress of the equalizing ring is detected to exceed the maximum stress safety threshold range and the maximum wind speed safety threshold range, an alarm is immediately triggered. When the alarm is triggered, emergency protection measures are initiated.
[0062] In step S2, the stress threshold in the core control module s max Based on the design strength of aluminum alloy materials and the stress values of different wind speeds and directions calculated by numerical simulation models, the relationship between the stress of the equalizing ring and the wind speed is established according to the on-site wind speed, that is, s = Ef (v 2 ), if the stress caused by wind s ( v 2 ) reaches the ultimate stress of the pressure equalizing ring s max When the stress generated by the incoming wind is 60%, the equalizing ring position needs to be adjusted to the strong side of stiffness; if the equalizing ring is adjusted, s ( v 2 ) reaches the ultimate stress of the pressure equalizing ring s max When the pressure reaches 80%, lock the pressure equalizing ring.
[0063] In step S4, the maximum stress safety threshold is set to 80% of the stress exceeding the limit, and the maximum wind speed safety threshold is set to the wind speed exceeding 30 m / s.
[0064] In step S4, the emergency protection measures include locking the angle of the pressure equalizing ring or starting the bypass support mechanism.
[0065] Through the above structural design and intelligent control method, The present invention can effectively cope with extreme weather conditions in high wind load areas. The design of the upper and lower double-layer structure of the equalizing ring enhances the overall stability and wind resistance. The combination of the core control module and the wind speed and direction sensor 4 realizes the real-time intelligent adjustment of the angle of the equalizing ring, and improves the wind resistance of the system. At the same time, the design of the early warning device can timely feedback extreme wind load information, providing reliable safety protection for maintenance personnel.

[0067] The present invention uses an intelligent control module and a rotating pressure equalizing ring design to automatically adjust the wind resistance direction of the equipment structure according to real-time wind speed and wind direction data. This adaptive capability enables the equipment to cope with variable wind load environments, avoids the limitations of traditional fixed structure designs, and significantly improves the wind resistance of the equipment.
[0068] By integrating the wind speed and direction sensor 4, the wind load data of the equipment's surrounding environment can be obtained in real time, and optimized and regulated through the intelligent algorithm of the core control module. This control method responds quickly and can make timely adjustments when the wind speed and wind direction change drastically, thereby ensuring the stable operation of the equipment.
[0069] The traditional pressure equalizing ring design requires regular manual inspection and maintenance, while the present invention can reduce equipment failures and damage caused by wind impact through intelligent adjustment methods, thereby significantly reducing maintenance costs and downtime.
