摘要：
本申请实施例提供一种继电保护设备及系统，涉及电路保护技术领域。所述继电保护设备包括继电保护终端及移动载体，其中，所述移动载体用于承载所述继电保护终端，便于其移动；所述继电保护终端用于采集待保护回路中的电压数据、电流数据以及待保护回路中的断路器的开关状态，并根据所述电压数据、电流数据及开关状态发出控制信号对待保护回路中的断路器进行控制，实现隔离电网故障。通过所述继电保护设备，可以在电力系统继电保护器件故障时代替其工作，保障电力回路的安全，同时避免更换继电保护器件的过程中因长时间无法供电对电网企业的服务质量造成影响。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The embodiment of the utility model provides a relay protection device and system, and relates to the technical field of circuit protection. Wherein the relay protection equipment comprises a relay protection terminal and a mobile carrier, and the mobile carrier is used for bearing the relay protection terminal so as to facilitate the movement of the relay protection terminal; the relay protectionterminal is used for collecting voltage data and current data in a to-be-protected loop and the on-off state of a circuit breaker in the to-be-protected loop, and sending a control signal to controlthe circuit breaker in the to-be-protected loop according to the voltage data, the current data and the on-off state, thereby achieving the isolation of a power grid fault. The relay protection devicecan replace a power system relay protection device to work when the power system relay protection device breaks down, the safety of a power loop is guaranteed, and meanwhile the situation that the service quality of a power grid enterprise is affected due to the fact that power cannot be supplied for a long time in the relay protection device replacement process is avoided.
