Icing Monitoring System of Transmission Lines Based on Image and Stress

In order to reduce the effects of conductor dancing, insulator flashover, and broken towers caused by icing disasters, solve the problem of traditional line icing detection methods and existing icing monitoring devices. An online ice monitoring device based on conductor coupling energy-acquiring technology and lens heating technology was developed. A high reliability and automatic icing monitoring and warning method was realized by combining the stress method equivalent icing thickness calculation model and the icing image recognition result. The pilot application in a 500kV transmission line can accurately monitor and warn the icing, and the practical application effect is good.
