Characteristics of Glass Insulator Hot Water Deicing

Abstract

Hot water is a kind of deicing medium with wide sources, and the impact force of its ejection is easy to control to avoid damaging the surface of glass insulator. In order to reveal the influencing factors of hot water deicing and their effect on the deicing time of glass insulator, an experiment was conducted where LXY-120 glass insulator was selected to measure the hot water deicing time under different circumstances. The results show that initial water temperature has significant effect on deicing time. At certain range, deicing time can be greatly reduced as initial water temperature increases, and it also affects deicing time increasement caused by heavier ice weight. Ejection distance and outlet pressure both have near linear relation with deicing time. It concluded that when conducting hot water deicing, on the premise of ensuring safety distance, shortening deicing distance, optimizing outlet pressure and initial water temperature can improve the ice melting efficiency.
