摘要
配网线路相间、接地故障频繁发生,大大降低了供电可靠性,影响了人们的日常工作和生活。要提高供电可靠性,除技术过硬的专业运行检修和抢修队伍外,还要使用高可靠、高性能的配网设备。在户外柱上开关设备中,SOG分界开关以自动隔离相间、单相接地故障线路及远程短信发送功能,使其在配网中被大量使用。但在安装使用中如果安装位置不合理,不但SOG分界开关的功能得不到很好的发挥,还会影响整条线路的供电可靠性。文中就SOG分界开关的应用条件进行简要分析,使它能更好地在配网中发挥出优势。
Inter-phase short circuit and ground fault occurs frequently in distribution network, greatly reduce the relia bility of power system, and affect people＇s daily work and life. In order to improve power supply reliability, not only need the operation overhaul and maintenance teams with excellent technology and experience, but also needs equipment with high reliability and high performance. In outdoor column switching equipment, SOG boundaries switch with automatic isolation interaction, single-phase ground fault line, and remote SMS sending function, has been widely used in the distribution net-work. But the installation position is unreasonable in the installation and use, not only the function of boundary SOG switch could not have a very good play, but also affect the reliability of the whole line of power supply. This paper briefly analyzed the application condition of SOG boundaries switch, so that it can take advantage of application in distribution network.
