摘要:
复合绝缘子运行过程中存在污秽累积和腐蚀硅橡胶伞裙的问题,绝缘子清洗也存在难度大成本高的问题。本文基于流体力学提出了一种适用于复合绝缘子的新型伞裙结构,从而达到提高绝缘子自洁能力的目的。这种伞裙主要依靠空气流过绝缘子时的循环运动来除去附着在绝缘子伞裙表面的沉积污秽物,通过空气动力结构的优化设计使得较大体积的颗粒物也能够被气流自然带离。该设计能够较好的应用于具有疏水性的硅橡胶涂层,试验结果表明当气流流过新型硅橡胶伞裙时,下降气流的速度总是大于上升气流的速度,从而使得颗粒沉积时间达到最短。结合硅橡胶的良好疏水性以及伞裙结构优势带来的良好自清洁性可以提高复合绝缘子的使用寿命。
Abstract:
There are problems of contamination accumulation and corrosion of silicone rubber sheds during the operation of composite insulators. The insulator is very difficult to clean, and the cost of cleaning is very high. In order to improve the self-cleaning ability of insulators, a new type of sheds structure which suitable for composite insulators is proposed based on fluid mechanics. This kind of sheds relies mainly on the circulation of air through the insulator to remove contamination attached to the insulator surface, and the larger deposition can also be taken away by the natural airflow. This design can be applied to the silicone rubber coating with hydrophobicity. The experimental results show that when the airflow goes through the new silicone rubber sheds, the descending speed is always greater than that of the updraft, so that the particle deposition time could be minimized. Combining the good hydrophobicity of the silicone rubber and the good self-cleaning ability brought by the structure advantage of the sheds, the life of the composite insulators can be improved.
