power off relay的意思|示意

When detecting standby signal, microcomputer gives structure to relay switch to cut off the current, then standby power is eliminated so as to realize energy saving.

在检测到待机信号时，单片机控制继电器开关，将电流切断，家电完全断电，消除了待机功耗，达到节能的目的。

Introduction was made to the composition and working principle of a power-off time delay relay which adopts CMOS digital circuit, digital dial disc for switch setting and without auxiliary power.

介绍了一种采用CMOS数字电路、数字拨盘开关整定、无辅助电源的断电延时继电器的组成及工作原理。

The proposed method can be used both on-line and off-line in the relay parallel setting and coordination of a large-scale power system.

该方法既适用于大电网继电保护离线并行整定计算又适用于在线并行整定计算。
