配电网中SF_6负荷开关组合电器的应用研究

Study on the application of SF_6 load switch composite apparatus in substations

SF6组合电器具有保护动作快速、简化电气接线、性价比高、维护工作量小等技术优点,是配电系统较理想的控制和保护设备,但在组合电器的选用、安装、运行维护和节能减排等方面尚需加强研究和管理。结合义乌市配电网建设,简要介绍了SF6负荷开关组合电器应用中需要注意的事项。

The SF6 load switch composite apparatus has the advantage of fast protection action, simplified electric connection, high performance -price ratio and low maintenance workload,so it is an ideal protection equipment for high voltage power transmission and distribution system. But research and management in its selection, installation, operation, maintenance and energy saving should be strengthened. The points of attention in the application of sulfur hexafluoride load switch composite apparatus in combining with the power grid planning and construction in Yiwu were briefly introduced.
