根据导线融冰的物理过程,提出了椭圆形气隙-冰层界面移动融冰模型,分析了融冰过程中冰层在重力作用下逐步下移过程,并在人工气候室中对模型的计算结果进行了试验验证.结果表明,在融冰过程中,随着冰层的融化,融冰水从空隙流失,冰和导线之间将形成椭圆形的气隙;融冰时间主要受电流密度、风速、环境温度以及冰厚等因素的影响.

@@@@An ice-melting model of moving elliptic air -gap and ice -face is put forward.The stepwise moving -down process of the ice layer due to gravity during the ice -melting is analyzed.The simulation results are testified in the artificial climate chamber.The results show that an elliptic air -gap is formed and widened gradually along with the ice melting and the ice-melting water dropping out.The influencing factors for ice -melting time include current density , wind velocity, ambient temperature and ice thickness etc .
