Problems solved by technology

[0002] At present, the monitoring device used to monitor the icing of overhead conductors mainly adopts the method of installing sensors on the cross-arms of fixed poles and towers to measure the tension of insulators or the inclination angle of insulators to indirectly measure the icing conditions in the spans on both sides of the sensor. The method has disadvantages such as cumbersome installation, small monitoring range, great influence of environmental factors on monitoring accuracy, difficulty in guaranteeing power supply, and easy interference of communication.
