高频融冰与交流短路融冰对比分析研究

高频融冰法作为一种新型的融冰方法,具有良好的应用前景。该方法不仅加深了融冰电流的集肤效应,使得热量更多的集中在导线表面与冰层完成热量的交换与传递,且利用冰在高频电场下的介质损耗热效应能直接引起发热。文中主要从融冰原理、临界融冰电流、融冰时间三个方面对高频融冰与交流短路融冰进行对比分析。并通过有限元分析软件ANSYS分别对以上三个方面进行仿真计算,仿真结果验证了高频融冰法与交流短路融冰法相比具有高效性、临界融冰电流相对较小及融冰时间短的优点。

Comparative Analysis of High Frequency Deicing and AC Short-circuit Deicing

High-frequency melting method has a good prospect as a new deicing method. This method not only increase the skin effect of deicing current, thus heat focus on the surface of wire and make heat exchange and transfer.with ice layer. And using the dielectric loss heat produced by ice polarization directly in the high frequency electric field. This paper mainly focus on principle,critical current,deicing time comparative analysis. And use finite element analysis software ANSYS simulate for the above three aspects, and ANSYS finite element analysis identified the high frequency de-icing method compared with the AC short-circuit de-icing method has advantages such as efficiency, lower critical de-icing currents and less deicing time.
