摘要(Abstract)：

合解环操作是电网运行中常见的操作。在配电网合解环操作过程中会形成电磁环网并产生环路电流,影响电网安全稳定运行。为了提高电网在合解环过程中的可靠性,避免长时间电磁环网和环路电流对电网设备产生冲击,设计了一种合解环装置,并通过在台州地区电网中的实际应用验证了该装置的可靠性。
The operation of closing/breaking loop is common in power grid.It may affect safe and stable operation of power system due to electromagnetically coupled power loop and loop current.In order to improve the reliability of the grid during loop closing and avoid the impact of long-time electromagnetically coupled power loop and loop current on devices in power system,this article describes the design of a loop closing/breaking device and verifies the reliability by its practical use in Taizhou power grid.
