Transmission line micro meteorological online monitoring device
model：DX-WPS100-QX
1、 Demand analysis
With the rapid development of the national economy, the demand for power from all walks of life is increasing, and the requirements for the quality of power supply (stability, continuity and accompanying services) provided by power supply departments are also increasing. In recent years, the occurrence of various bad weather, such as typhoon, ice cover, mountain fire disasters, has caused considerable losses to the power transmission lines of power grid companies, and a set of online micrometeorological monitoring devices for power transmission lines is urgently needed, Real time monitoring of the real-time data of the meteorological environment provides strong data support for the occurrence of meteorological disasters and post disaster reconstruction, so as to take preventive measures in advance and reduce the adverse impact of abnormal weather on the safe operation of substation equipment.
2、 Working principle
The monitoring unit of the transmission line micrometeorological online monitoring device is installed on the line tower to monitor the environmental temperature, humidity, wind speed, wind direction, rainfall, atmospheric pressure, light radiation and other parameters. The collected parameters are analyzed and processed by the data processing transmission unit after the sensor is collected, and various interference factors are removed, and uploaded to the monitoring center for storage, analysis and processing; Through this device, the meteorological data of the line's micro meteorological area can be known in time, and countermeasures can be formulated in case of emergency, so as to take preventive measures in advance and reduce the adverse impact of abnormal weather on the safe operation of substation equipment; Through the accumulation, statistics and analysis of long-term micro meteorological data at monitoring points, it can provide strong data support for the occurrence of meteorological disasters and post disaster reconstruction, and provide operation data accumulation for later line operation and maintenance and other new line design and operation.
