AI Technical Summary

Technical Problem

Existing icing layer testing devices and methods cannot accurately characterize the radial fracture strength of ice ridges on transmission lines, lack specialized testing means, and cannot support the research and optimization of anti-icing and de-icing technologies for transmission lines.

Method used

A test device was designed, which includes an ice crystal growth module, a clamping mechanism, and a thrust application and detection system. By simulating ice crystal growth in a low-temperature environment, the ice crystal is clamped using an adjustable gripper assembly, and the thrust value is recorded in real time to calculate the radial fracture strength of the ice crystal.

Benefits of technology

It enables accurate measurement of the radial fracture strength of ice ridges under conditions closer to natural conditions, providing reliable data support for anti-icing and de-icing technologies for power transmission lines, and ensuring the accuracy and reliability of the test.
