Save the power "ice world": transmission line ice-covered online monitoring device, the pull type to protect the power grid to meet the winter peaks

After the winter, China's temperature continues to go down in many places, especially in the northeast, under the influence of the cold wave, but also ushered in a record-breaking blizzard, part of the city snowfall amounted to 40.7 millimeters, snow depth of up to 30 centimeters, as if the overnight "freeze".



Transmission line operation is also struggling in this snow and ice predicament. Thick snow and ice covered in transmission line wires, towers, insulators... Proper power "ice world". But the reality is not good, these ice to the transmission line brings extra weight, easy to trigger the conductor broken strands, broken line, and in serious cases will even lead to the tower tilt, collapse. And the ice reduces the insulation level of insulator strings, which may lead to insulator string short-circuit, resulting in grounding accidents; gold tools to withstand a larger horizontal force, easy to damage.

Facing the severe test brought by snow and ice to the power artery, our company launched Transmission line ice-covering online monitoring deviceDX-WPS100-FB, to see how it protects the power grid to meet the winter peak!



composition

Transmission line ice cover online monitoring device consists of inclination/tension integrated sensor, miniature weather station, high-definition camera, main control module, communication module, power supply system and monitoring backend, adopting low-power consumption design, stable and efficient operation.



Line ice monitoring and early warning

1. Ice cover thickness monitoring

Transmission line ice-covering online monitoring device through real-time measurement of conductor tension, insulator tension, insulator inclination (lateral deflection angle, along the line deflection angle), combined with ambient temperature, humidity, wind speed, wind direction and other data, the use of the system's intelligent algorithms can be accurately calculated conductor ice-covering thickness, to provide a reference for the line de-icing.

2. Prediction of ice cover trends

1 set (group) of meteorological sensors with the function of collecting ambient temperature, relative humidity, wind speed and wind direction, capable of real-time monitoring of changes in ambient temperature, humidity, wind speed and wind direction of the line, intelligently determining the conditions for the start of the ice-covering calculation and giving the trend of the development of ice-covering, so as to facilitate the taking of precautionary measures in advance.

3、Integrated spherical camera - visualization of ice-covered monitoring

Integrated spherical camera 1 set, through the front-end high-definition camera collection of transmission equipment body and its surrounding site image, wireless back to the background monitoring center, to achieve visualization of the ice, to help operation and maintenance personnel to grasp the real-time conductor, tower ice-covered state, to ensure that the line is safe to run.

The application of the tensile equivalent transmission line ice-covering online monitoring device provides important data support for the safe and stable operation of the power grid, reduces the pressure of manual ice-covering inspection work, prevents power accidents caused by line ice-covering, and improves the scientific management level of power grid operation and maintenance.
