硅橡胶在电力系统外绝缘中的应用研究
|
摘要
近几年,我国开始广泛运用硅橡胶线路绝缘子,以此有效提升电力系统的外绝缘水平。目前,我国已成为全球第一个在直流输电系统与特高压交流输电中以有机外绝缘为主的国家。现阶段,输变电行业飞速发展,进一步扩大了以有机材料和无机材料作为绝缘材料的运用范围。但是,电压等级的进一步提高导致污闪事故频繁发生,从而造成大量的人员伤亡和经济损失。面对这一现象,人们开始重视硅橡胶的应用研究。
In recent years,silicone rubber line insulators have been widely used in China to effectively improve the external insulation level of power system. At present,China has become the first country in the world to mainly use organic external insulation in HVDC and UHV AC transmission systems. At present,with the rapid development of power transmission and transformation industry,the application scope of organic and inorganic materials as insulation materials has been further expanded. However,the further improvement of voltage level leads to frequent pollution flashover accidents,resulting in a large number of casualties and economic losses. Faced with this phenomenon,people began to pay attention to the application of silicone rubber research.
