Research on Value-Seeking Calculation Method of Icing Environmental Parameters Based on Four Rotating Cylinders Array

This paper calculates and analyzes the collision freezing characteristics of water droplets on cylindrical conductors with different diameters deduces variation law icing weight change rate rotating wind speed, ambient temperature, liquid content, median volume diameter. Then, a prediction value-seeking method environment parameters based circular is determined. The laboratory test results show that measured values temperature T, speed U, content w diameter MVD are in good conformity reference by other instruments, average errors each parameter 3.41%, 5.44%, 6.08% 7.20%, respectively. field natural experiment was carried out at Hunan Xuefengshan Energy Equipment Safety National Observation Research Station. obtained environmental were substituted into simulation calculation model LDQ-100 glass insulator. Compared results, simulated ice shape agreement. error between numerical experimental insulator less than 6%.
