农村剩余电流动作保护智能终端设计方案探讨

Design Discussion on Aftercurrent Action Protection Intelligent Terminal in Rural Area

在分析农村400V电网剩余电流动作总保护器跳闸原因的基础上,得出了用户端设备故障是其主要原因的结论。提出了剩余电流动作保护智能终端的架构和功能设计方案,并且分别提出了智能终端通信方式、动作保护和监控报警模块、远程监控中心软件的设计方案。该智能终端可减少因家用剩余电流动作保护器故障造成的总保护器越级跳闸,从而提高供电可靠性。

Based on the analysis of the cause of rural 400 V aftercurrent action protector trip,the architecture and function of aftercurrent action protection intelligent terminal is proposed.Feasibility of the proposed method is researched in terms of communication mode,hardware and software of monitoring and alarm module,and the auxiliary functions is discussed as well.
