摘要:
风对雨雪冰冻气候下输变电设备表面覆冰有重要的影响,是研究设备覆冰机理、导线融冰的重要参数 之一,但在人工环境下获得均匀稳定风的难度很大。文中介绍了具有均匀风功能的人工覆冰气候室的基本 情况,基于自由射流理论,通过仿真计算、冰风洞缩比试验和人工覆冰气候室实际测试,试验表明:采用吹风 方式比吹—吸风方式和吸风方式在风机功率和风的均匀性方面更有优势;通过优化设计风洞结构,可以在 人工覆冰气候室内实现稳定的均匀风;均匀风对人工气候室内温度分布影响较小。该研究可以为研究风对 输变电设备表面覆冰的影响及覆冰增长规律提供技术支持。
Abstract:
Wind has an important influence on surface icing of power transmission equipment under the freezing rain and snow weather,and which is one of the important parameters for researching icing mechanism of equipment and ice?melting of conductors,but it is very difficult to obtain uniform and stable wind in the artificial environment. This paper introduces the basic situation of artificial icing climate chamber with uniform wind. Based on the theory of free jet,it is proved through simulation calculation,wind tunnel scaling test and actual test in the artificial icing climate chamber that: Blowing mode is better than blowing?absorbing mode and absorbing mode in fan power and uniformity of wind. Also,uniform and stability wind can be achieved in the artificial icing climate chamber through the optimiza? tion design of tunnel structure. Uniform wind has little effect on the temperature distribution in the artificial climate chamber. This research can provide technical support for the effects of wind on the surface of transmission equipment icing and ice accretion rules.
