产品详细资料
将电流设置为额定CT次级。 检查跳闸和拾取指示灯是否点亮，并显示以下跳闸信息之一：锁定：过频或操作：过频 缓慢降低频率，直到拾取器LED和输出继电器复位。 注意脱落水平，该水平应为拾取器减去0.03 Hz。检查跳闸LED是否仍亮。如果OVERFREQUENCY TARGET（频率过高目标）设置为“Latched”（锁定），则跳闸信息仍亮；如果设置为“自复位”，则当频率低于设定值时，消息复位。对于定时测试，信号发生器必须能够在几毫秒内触发频率的逐步变化或斜坡下降到预先选择的频率。 连接信号源和定时器启动触发器，如图7-12所示：第7-44页的频率元件测试。 将电压设置为额定VT次级值，将电流设置为额定CT次级值，并将预触发频率设置为标称频率（60或50 Hz）。如果未对此元件启用电流感测，则不需要电流信号。 将后置触发器设置为高于过频元件设置0.5 Hz。如有必要，重置所有目标和继电器。 重置计时器。 启动频率步进和定时器启动。间隔计时器记录元件的工作时间。
Set the current to rated CT secondary.  Check that the Trip and Pickup LEDs are on and one of the following trip messages is displayed: LATCHED: Overfrequency or OPERATED: Overfrequency  Slowly decrease the frequency until the Pickup LED and output relays reset.  Note the dropout level, which should be the pickup minus 0.03 Hz. Check that the Trip LED is still on. The trip message remains on if the OVERFREQUENCY TARGET setting is “Latched”; if set to “Self-resetting”, the message resets when frequency is below the setpoint. For timing tests, the signal generator must be capable of triggering into step-wise changing of frequency or ramping down to a pre-selected frequency in only a few milliseconds.  Connect the signal source and timer start triggers as shown in FIGURE 7–12: Frequency element testing on page 7–44.  Set the voltage to rated VT secondary value, the current to rated CT secondary, and the pre-trigger frequency to nominal frequency (60 or 50 Hz). The current signal is not required if current sensing is not enabled for this element.  Set the post-trigger to 0.5 Hz above the setting of the overfrequency element. If necessary, reset all targets and relays.  Reset the timer.  Initiate the frequency step and timer start. The interval timer records the operating time of element.
