产品详细资料
小拾波A相元件的工作电平是通过向端子H1和G1施加交流电流来测量的。当电流从0 A增加时，监测适当的跳闸和辅助触点。由于自动配置功能，读取继电器上的实际差动电流可能更容易，而不是计算它。 将检测到操作的差分电流值与S4元件进行比较 仪表差速器 INST DIFFERENTIAL PICKUP设定点。检查跳闸和信息LED是否闪烁，并显示以下跳闸信息：LATCHED a（bc）INST DIFFERENTIAL。注意：如果TARGET（目标）设置点为“SelfReset”（自复位），则消息可能显示OPERATED（操作）而不是LATCHED（锁定）。7.5.3.3操作时间测量瞬时差动元件的基本操作时间， 通过双极单掷开关将交流电流信号连接到端子H1和G1。开关的第二极启动计时器电路，该电路将因继电器跳闸触点的操作而停止。参见第7–19页图7–5：定时器测试电路。 闭合开关并将电流水平设置为先前测量的拾取值的两倍。 重新打开开关并重置继电器上的所有目标。 确保定时器电路工作正常。 合上开关并记录继电器的工作时间
Minimum Pickup The operating level of the phase A element is measured by applying an AC current to terminals H1 and G1. Monitor the appropriate trip and auxiliary contact(s) as the current is increased from 0 A. Due to the auto-configuration feature, it may be easier to read the actual differential current on the relay rather computing it.  Compare the value of the differential current at which operation is detected against the S4 ELEMENTS  INST DIFFERENTIAL  INST DIFFERENTIAL PICKUP setpoint.Check that the Trip and Message LEDs are flashing and the following trip message is displayed: LATCHED a (bc) Inst Differential. Note The message may show OPERATED instead of LATCHED if the TARGET setpoint is “SelfReset”. 7.5.3.3 Operating Time To measure the basic operating time of the instantaneous differential elements,  Connect an AC current signal to terminals H1 and G1 through a doublepole, single-throw switch. The second pole of the switch starts a timer circuit that will be stopped by the operation of the relay trip contact. Refer to FIGURE 7–5: Timer test circuit on page 7–19.  Close the switch and set the current level to two times the pickup value measured earlier.  Re-open the switch and reset all targets on the relay.  Ensure that the timer circuit functions correctly.  Close the switch and record operating time of relay
