What is a transmission line microweather station?

It's part of a microweather station on a transmission line.

It is composed of solar panels, equipment boxes, micro meteorological instrument, transmission system, etc., can measure wind speed, wind direction, temperature, humidity, atmospheric pressure, piezoelectric rainfall and other elements online all weather.

Moreover, the collected meteorological data can be sent to the system host through the network, and then the system will store, count and analyze the meteorological data. Power supply employees can use this data to determine the weather conditions in the line area, so as to schedule targeted inspection activities.

The micro meteorological instrument is a meteorological sensor with high integration, integrated structure and neat appearance. It can measure wind speed, wind direction, temperature, humidity, atmospheric pressure, piezoelectric rainfall and other data

1. Wind measurement, built-in 4 ultrasonic probes can measure 360° all-round change of wind direction, with ultrasonic time difference method to measure wind speed, can output wind speed and wind direction data at the same time, and is not affected by the starting wind speed, mechanical parts.

Wind speed measurement range 0 ~ 60m/s (±0.1m/s), wind direction measurement range 0 ~ 360° (±2°);

2. Temperature measurement, measuring range -40-60℃ (±0.3℃), measuring principle diode junction voltage method, resolution 0.01℃;

3. Humidity measurement, measurement principle capacitive, 0-100%RH (±3%RH), resolution: 0.1%RH;

4. Measurement of atmospheric pressure, measuring principle piezoresistive, 300-1100hpa (±0.25%), resolution 0.1hpa;

5. Piezoelectric rainfall measurement, measuring range 0-4mm/min, measuring accuracy ≤±4%, resolution 0.01mm.

Although the transmission line has certain resistance, the weather such as wind, rain and snow has an impact on its operation, and most of them are located in the field, and the conventional weather forecast is difficult to meet the demand in terms of timeliness and accuracy, so the transmission line micro-weather station is needed to provide more accurate meteorological services.
