电 系统继电器由两个可调定时功能组成。一个定时器称为UV定时器(可调范围为0.2-6秒),它限制了控制电源可能因自动重启而中断的时间。如果中断持续时间超过计时器设置,电机将不会在恢复电源时重新启动,需要手动重新启动。如果在计时器超时之前恢复电源,则电机将在二次计时器延迟后自动重新启动。二个计时器称为重启延迟计时器(可在0.2-60秒范围内调整),是控制电源恢复后的重启延迟。二个定时器可以设置为允许转子电流在电源中断后衰减,以便电机(尤其是同步电机)不会在磁场或鼠笼电流存在的情况下失相重新通电。一组电机控制器中的电机自动重启继电器可以独立设置,以允许电机在一段时间内交错重启,从而将对电力系统恢复供电的影响降至低。继电器还具有区分控制电源中断和“停止”按钮操作的功能system. The relay consists of two adjustable timing functions. The first timer, called the UV timer (adjustable from 0.2 - 6 seconds) limits the time the control power may be interrupted for an auto-restart to occur. If the interruption lasts longer than the timer setting, the motor will not restart on restoration of power and a manual restart will be required. If power is restored before the timer times out, then the motor will restart automatically after a second timer delay. The second timer, called the restart delay timer (adjustable from 0.2 - 60 seconds) is a delay on restart following restoration of control power. This second timer can be set to allow time for rotor currents to decay following an interruption of power, so that a motor (particularly a synchronous motor) is not re-energized out of phase with field or squirrel-cage current present. Motor auto-restart relays in a group of motor controllers can be independently set to allow for a staggered restart of motors over a period of time to minimize impact to the power system on restoration of power. The relay also has the feature of distinguishing between control power interruptions and “STOP” pushbutton operations
