远程复位模式验证 将差速器元件设置为锁定目标。 施加足够的电流使继电器工作,然后消除电流。跳闸指示灯和相位指示灯应锁定。 设置S1 745设置 复位 远程复位信号至逻辑输入1(16)。 断言逻辑输入1。目标应该重置。7.5.2.5固态输出的验证如果固态输出用于驱动辅助继电器, 验证这些继电器在继电器处于跳闸状态时是否工作。 确保通过辅助线圈的电流在每次测试之间被外部接触器中断。当固态输出直接操作断路器时,为了避免在调试过程中操作断路器, 使用下面所示的电路来验证此输出。每当继电器处于跳闸状态时,电流就会流过负载电阻器。 在继电器方案中使用的正常直流电源电压下,选择约1×CT直流电流的电阻器。要测量谐波抑制差动元件的基本工作时间, 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,计时器电路因继电器跳闸触点的操作而停止。有关详细信息,请参阅下图。 闭合开关,将电流水平设置为先前测量的小拾取值的三(3)倍。
Verification of Remote Reset Mode Set the differential element with a latched target. Apply enough current to cause the relay to operate, then remove the current. The Trip LED and the Phase LED should be latched on. Set S1 745 SETUP RESETTING REMOTE RESET SIGNAL to Logic Input 1(16). Assert logic input 1. The target should reset. 7.5.2.5 Verification of Solid-state Output If the solid-state Output Is Used To Drive Auxiliary Relays, Verify that these relays operate whenever the relay is in a trip condition. Ensure that the current though the auxiliary coils is interrupted by an external contactor between each test. To avoid operating the breaker during the commissioning process when the solid-state output operates the breaker directly, Use the circuit shown below to verify this output. Whenever the relay is in a trip state, current flows through the load resistor. Select the resistor for approximately 1 × CT of DC current with the normal DC supply voltage used in your relay scheme.To measure the basic operating time of the harmonic restrained differential elements, Connect an AC current signal to terminals H1 and G1, through a double-pole single-throw switch. The second pole of the switch starts a timer circuit which is stopped by the operation of the relay trip contact. Refer to the figure below for details. Close the switch and set the current level to three (3) times the minimum pickup value measured earlier.
