      According to the Central Weather Bureau news, 25-28 days, is expected to be affected by the weak cold air, most parts of China will have 3-6 ℃, the localities up to 8 ℃ of cooling; most of the central and eastern regions have light rain, the eastern part of the Tibetan Plateau has a small to medium snow or sleet, the localities of large to heavy snow.

      Cold air is coming, part of the transmission line is also about to face a "ice" and "electricity" competition. Today, we will talk about transmission line ice, as well as guarding the grid safety "superhero" - transmission line to see the ice elves.


      Transmission Line Ice Cover Formation and Hazards

      The formation of transmission line ice cover involves a variety of meteorological factors and environmental conditions, including air humidity, wind speed, and air temperature. The main types of ice cover include wet snow, freezing fog, freezing rain and mixed freezing, among which freezing rain and mixed freezing hazards.



      1, weight overload: ice cover increases the weight borne by the conductor, insulator string and tower, and when it exceeds the permissible value of the strength of the components, it will lead to line force imbalance, arc sag increase, tower tilt and other problems;

      2, the insulation strength is reduced: after covering the ice, the leakage resistance of the insulator string decreases, and the unevenness of voltage distribution increases, which may lead to ice flash accidents;

      3, ice-covered dance: uneven ice-covered conductor in the wind excitation produces self-excited vibration, may lead to the gold and insulator damage, conductor strand breakage, wire breakage, and even down tower.

      Our Transmission Line Ice Watch WizardDX-WPS100-JL is a kind of online monitoring device for ice cover, integrating multiple sensors and AI algorithms, capable of real-time monitoring of conductor ice cover, including ice cover thickness, ice cover image, as well as ambient temperature, relative humidity, wind speed, wind direction and so on. At the same time, it has real-time wire temperature measurement and current monitoring functions, which can provide reliable data support for line dynamic capacity increase, line tensioning clamp heat monitoring, line DC ice melting and other fields.




      Technical characteristics

      1、Ice cover monitoring: Collect line ice cover images through high-definition cameras, analyze the image information with built-in AI algorithms, identify the basic morphological characteristics and thickness of the ice cover, and identify the equivalent ice cover thickness up to 50mm;

      2、Intelligent warning: when the thickness of ice cover and monitoring data exceeds the set safety threshold, the system will automatically warn you;

      3、Maintenance-free power supply: Adopting AC inductive power extraction technology, high power extraction, combined with ultra-low power consumption processing circuit design, can realize all-weather monitoring;

      4, lens antifreeze: the lens has an intelligent defogging, antifreeze function to prevent the lens from fogging at low temperatures, ice buildup, and improve the reliability of monitoring;

      Flexible communication: support WIFI/4G/5G network, 4G module supports APN dedicated network access to realize secure transmission on dedicated network.





      Installation

      The device adopts curved surface design, aluminum alloy shell, strong anti-electromagnetic interference ability, can be directly installed in the transmission line conductor, protection grade IP67, can adapt to a variety of harsh environments, can be maintenance-free operation time ≥ 5 years.
