RADISYS RS232数字量控制板卡

产品详细资料
小通电电压：输入电压水平，低于该电压水平时，变压器被视为断电（当通电感应电压为“启用”时）。只有当S2 SYSTEM SETUP（S2系统设置）时，才会显示此设置点 电压输入 电压感应处于“启用”状态。•BREAKERS ARE OPEN SIGNAL（断路器断开信号）：选择任何逻辑输入，该逻辑输入在断言时向745指示变压器断电。所选逻辑输入应连接到变压器断路器或隔离开关的辅助触点。•PARALL XFMR BRKR CLS SIGNAL：选择任何逻辑输入，当断言时，将向745指示交感神经涌入的开始。所选逻辑输入应连接到通往并联变压器开关设备的闭合命令。百分比差动元件的五次谐波抑制功能允许在系统有意过励磁期间抑制百分比差动。如果同一相位的5次谐波超过谐波抑制电平设置，此功能将抑制特定相位中的差分元件百分比。在启用谐波平均的情况下，如果第5次谐波的三相平均值超过电平设置，则禁止所有三相。
MINIMUM ENERGIZATION VOLTAGE: Enter the voltage level below which the transformer is considered de-energized (when ENERGIZATION SENSING BY VOLTAGE is “Enabled”). This setpoint is displayed only if S2 SYSTEM SETUP  VOLTAGE INPUT  VOLTAGE SENSING is “Enabled”. • BREAKERS ARE OPEN SIGNAL: Select any logic input which, when asserted, indicates to the 745 that the transformer is de-energized. The selected logic input should be connected to the auxiliary contacts of the transformer breaker or disconnect switch. • PARALL XFMR BRKR CLS SIGNAL: Select any logic input which, when asserted, will indicate to the 745 the onset of sympathetic inrush. The selected logic input should be connected to the close command going to the parallel transformer switching device.The 5th harmonic inhibit feature of the percent differential element allows inhibiting the percent differential during intentional overexcitation of the system. This feature inhibits the percent differential element in a particular phase if the 5th harmonic of the same phase exceeds the harmonic inhibit level setting. With harmonic averaging enabled, all three phases are inhibited if the three-phase average of the 5th harmonic exceeds the level setting.
