With the arrival of winter, the temperature is getting lower and lower, China's northern and mountainous areas of the transmission lines are facing the severe test of ice cover. Overhead transmission line ice will cause insulator flash, wire dance, flashover and other electrical accidents, as well as conductor broken strands, fixture damage, tower tilt collapse and other mechanical accidents, seriously affecting the stability of power supply and grid security. In order to improve the power grid ice resistance, it is imperative to actively carry out ice monitoring. To this end, our company proposed Transmission Line Ice Cover Online Monitoring Device based on microwave detection principle.
Application of Microwave Ice Cover Monitoring Device DX-WPS100-FB3 for Power Transmission Lines
1, ice thickness monitoring: using microwave detection technology, based on the microwave signal and ice, water, air and other different substances interacting with the difference between the feedback signal characteristics, through the microwave sensor to monitor the transmission line ice-covered situation, and according to the signal strength and distribution information to calculate the thickness of ice. The measured thickness is 50.00mm and the detection resolution is 0.01mm.
2、Meteorological parameter monitoring: the system can monitor the environmental temperature, humidity, atmospheric pressure, wind speed, direction, rainfall and light radiation in real time, and automatically store and upload the data to the backstage to provide reference for the assessment of the risk and extent of ice-covering.
3, early warning function: the system can be based on the thickness of icing and changing trends, issued in advance warning information to facilitate timely line operation and maintenance and de-icing work.
4, power outage-free installation: microwave ice-covered monitoring device does not require power outages to install, to avoid the loss of power outages caused by the installation.
Technical characteristics
1、Wireless communication: support all-network 4G/5G/WIFI wireless transmission, communication with the main station can use VPN dedicated channel, optional encrypted transmission;
2, data access: can be accessed in accordance with the relevant specifications of the South China Grid, State Grid and other provincial power companies monitoring platform;
3, online positioning: the device has a positioning function, and can upload real-time location information;
4, power supply: power supply including solar panels, batteries and power controllers three parts, with over-voltage protection, anti-overcharge and over-discharge and other functions;
5, high protection: the use of high-quality sealed metal box, with good resistance to industrial frequency electromagnetic interference performance and good grounding installation measures, to achieve accurate and complete collection of video data in a high-voltage electromagnetic environment.
