Experiment and simulation of icing on overhead transmission lines
摘要
Abstract
An experimental investigation of icing on overhead transmission lines was carried out in an open cycle icing wind tunnel located in a climatic chamber. Loads and density of ice were measured and ice type was observed every hour of 6 h duration of icing. Comparisons and error analysis were made between the experimental data and those predicted by unproved heat balance model. The results show that as the air temperature gradually increases from -10 °C to -2 °C, the icing process starts dry-growing (rime ice) and then changes into wet-growing (glaze ice). With the increase of ice density, the increase of wind speed will result in the growth of the ice loads. But if the liquid water content is high, the icing process is wet-growing even at low temperature. Using the improved icing model, the prediction on the wire ice loads is comparatively consistent with the experimental results.关键词
