摘要 近年来,随着电力系统的迅猛发展,由于受产品质量、安装工艺、日常维护、环境温度等因素的影响,变电站内隔离开关的运行环境愈发重要。尤其是目前大部分变电站内值守人员都有所减少,市区内的低电压等级变电站都是无人值守变电站,在这种情况下,隔离开关的可靠运行显得更加重要。因此,强化变电站隔离开关的关键技术的研究具有极其重要的现实意义。本文针对隔离开关的基本原理进行了简要介绍,对于几类常见的隔离开关缺陷进行了研究,针对性的给出了解决常见缺陷的有效措施,提出了隔离开关的维护方法和选型关键点,对运检工作的高效开展有着现实指导意义。 In recent years,with the rapid development of power system,due to the influence of product quality,installation technology,daily maintenance,environmental temperature and other factors,the operating environment of the disconnectors in substations becomes more and more important.Especially at present,most of the substation attendants are reduced,and the low-voltage substations in the urban area are unattended substations.In this case,the reliable operation of the disconnector is more important.Therefore,it is of great significance to strengthen the research on the key technology of substation disconnector.In this paper,the basic principle of the disconnector is briefly introduced.Several kinds of common defects of the disconnector are studied.The effective measures to solve the common defects are given.The maintenance methods and key points of type selection of the disconnector are put forward,which has practical significance for the efficient development of the operation and inspection work。
