With the continuous change of temperature, especially the people of Guangzhou, these two weeks have really experienced the feeling of "two days", then, the next Shenzhen Dingxin Wisdom Technology will start from the micro-terrain and micro-meteorology of the power grid, and give you the popular science power micro-meteorological monitoring and early warning system (transmission line micro-meteorological monitoring device).
What is the microtopography of an electric transmission line?Microtopography is generally a relatively small surface morphology that has a significant impact on the local climate and environment in a small scale. These micro-terrain forms may include valleys, hills, plains, wetlands, rivers, alpine watersheds, etc., which not only affect the layout and design of power transmission lines, but also affect the operation and maintenance of power transmission lines. In some areas with complex terrain, the line is more likely to suffer from natural disasters such as **, landslides, and mudslides, which may cause damage to the line or interrupt the power supply. In addition, in some wetlands or swampy areas, the line may also be affected by flooding or corrosion, which can also increase the difficulty and cost of maintenance.
What is the micrometeorology of power transmission lines?In fact, it is a small range of climate formed in a local small environment due to the difference in the properties of the underlying surface, and these micrometeorological conditions generally include temperature, humidity, wind speed, wind direction, air pressure, etc.
Whether it is in the design and construction of power transmission lines, or in the process of operation and maintenance, it is necessary to fully consider the influence of micro-terrain and micro-meteorology, so as to take corresponding measures to ensure the safe and stable operation of the line.
The power micro-meteorological monitoring and early warning system belongs to the "seven elements" meteorological monitoring system, and the meteorological sensors laid in the wire can monitor meteorological data in real time, such as environmental temperature, humidity, wind speed, wind direction, rainfall, atmospheric pressure, optical radiation, etc., as well as the operation status of power equipment, and return to the monitoring center through the analysis of these data, and judge the possible power equipment failure or power network problems, so as to provide more accurate data support for the operation of power enterprises. When meteorological conditions are abnormal, the system will immediately send out an early warning signal to remind power companies to take timely measures to avoid or reduce power equipment failures and power network problems.
