    • PROBLEM TO BE SOLVED: To provide a protection relay system which protects a transmission line by multistep time limit differential distance relaying system, when the main protective function of a main protection relay, disposed at each terminal of a protected transmission line and capable of transmitting the apparatus information, has been lost.SOLUTION: Upon elapsing a predetermined time limit after a fault occurring in the counter terminal direction of a transmission line 1L is detected, a back-up protection relay 2A outputs an interruption command to an interruptor CBat its own terminal. When the interruption information of an interruptor CBat the counter terminal is acquired by an interruption information acquisition unit 24 among the apparatus information transmitted from the main protection relay 1B at the counter terminal to the main protection relay 1A at its own terminal, an interruption command is output to the interruptor CBat its own terminal while reducing a predetermined time limit.
    • 要解决的问题:为了提供一种保护继电器系统,其通过多步时限差距继电系统保护传输线,当主保护继电器的主要保护功能设置在受保护的传输线的每个端子并且具有能力 发送设备信息,已经丢失了。 解决方案:检测到在传输线1L的计数器端子方向发生故障之后经过预定的时间限制,备用保护继电器2A向中断器CB A1 在自己的终端。 当从计数器终端从主保护继电器1B发送的装置信息中的中断信息获取单元24获取在计数器终端处的中断信号CB B1 的中断信息时, 主保护继电器1A在其自身的端子处,在其自身端子处将中断命令输出到断开器CB A1 ,同时减少预定时间限制。 版权所有(C)2013,JPO&INPIT
