Description

Technical Field

[0001] The present invention relates to the fields of energy technology and power transmission equipment monitoring technology. Specifically, the present invention relates to a high-frequency real-time synchronous portable measurement system, which is mainly used for measuring multiple factors such as wind speed, temperature, humidity and radiation on high-voltage transmission towers. Background Art

[0002] High-voltage transmission lines can be subject to ice accumulation and vibration under extreme conditions. Icing significantly increases the weight of transmission lines, potentially causing increased conductor sag, unbalanced tower forces, and even line breakage or tower collapse. Ice covering conductors reduces the effective current cross-section, lowering transmission capacity. Furthermore, the increased conductivity of the ice layer can cause insulator flashover or short circuits. Vibration can lead to line tripping, outages, and component damage. Therefore, research on ice accumulation and vibration in transmission lines has long attracted considerable attention.

[0003] Existing research on turbulent motion in the atmospheric surface layer indicates that high-Reynolds-number wall turbulence in the atmospheric surface layer contains not only small-scale turbulent motion with random characteristics, but also large-scale and ultra-large-scale turbulent motion with coherent structure characteristics. These large-scale turbulent motions contribute significantly to the turbulent kinetic energy, and their contribution increases with altitude. Furthermore, existing numerical and experimental studies on the effects of turbulent motion in the atmospheric surface layer on sand and dust particle transport have shown that: 1) near the surface, large-scale and ultra-large-scale turbulence significantly influences saltation sand motion; 2) in the upper atmospheric surface layer, large-scale turbulence dominates the vertical transport of dust and heat, indicating a high correlation between dust concentration fluctuations and large-scale turbulent fluctuations. These studies have shown that the effects of turbulent fluctuations and dust loads, particularly large-scale dust load fluctuations, on transmission lines cannot be ignored in the design of transmission lines and in predictive models of transmission line motion.

[0004] Research on icing of transmission lines indicates that a conductor surface temperature below 0°C in the atmospheric surface layer is essential for icing to form. Air humidity must be greater than 85%, meaning that there must be freezable moisture or supercooled water droplets, fog droplets, and water vapor in the air. Wind speeds between 1 and 15 meters per second favor icing, with higher wind speeds contributing to thicker icing. Icing is also more common in areas where cold and hot air currents converge and in areas with micro-topography and micro-climate conditions, indicating that local meteorological conditions can influence icing.

[0005] In summary, prediction models for both transmission line vibration and icing must consider physical quantities such as wind speed, temperature and humidity, and dust concentration. Therefore, it is necessary to synchronously monitor atmospheric physical quantities near transmission lines. This allows for accurate predictions of transmission line vibration and icing during extreme weather conditions and in complex terrain, such as areas difficult for humans and drones to reach, thus supporting the safe operation of transmission lines.

[0006] However, in the prior art, there is no efficient method or device for real-time synchronous high-frequency measurement of wind speed pulsation, dust concentration pulsation and other atmospheric environmental physical quantity pulsation near transmission lines.

[0007] To solve the aforementioned problems, the research and development team of this application has developed a high-frequency real-time synchronous portable measurement system after long-term experimental research, which is used to measure multiple factors such as wind speed, temperature, humidity and radiation on high-voltage transmission towers. Summary of the Invention

This system is easy to use and can transmit data remotely, offering multiple functions, easy installation, and real-time data acquisition.
