RADISYS EXM100工控控制卡件

产品详细资料
745可以通过称为模拟输入的通用辅助电流输入来监测任何外部量，例如总线电压、电池电压等。标准转换器输出范围0至1 mA、0至5 mA、4至20 mA或0至20 mA中的任何一个都可以连接到模拟输入端子。在S2 SYSTEM SETUP（S2系统设置）中配置模拟输入 模拟输入和A2 METERING中显示的实际值 模拟输入。本节包含配置当前需求监测元件的设置。包括每个绕组的电流需求水平。变压器过载拾取：此设置确定变压器过载的水平，拾取延迟开始计时。设置以变压器基本MVA额定值的百分比表示，通常设置为或高于变压器铭牌上的大额定MVA。•XFMR OVERTEMP ALARM SIGNAL（变压器过热警报信号）：选择任何逻辑输入，当断言时，指示变压器冷却系统发生故障并且存在过热情况。逻辑输入应连接到变压器绕组温度报警触点。分接开关故障元件监测分接开关监测电路看到的电阻。当分接开关位置超过大分接数量（由分接位置数量设置点设置）2时，该元件产生输出信号。该信号可用作警报或改变设定点组的信号。设定点组的变化将通过FlexLogic进行编程™
The 745 can monitor any external quantity, such as bus voltage, battery voltage, etc., via a general purpose auxiliary current input called the analog input. Any one of the standard transducer output ranges 0 to 1 mA, 0 to 5 mA, 4 to 20 mA, or 0 to 20 mA can be connected to the analog input terminals. The analog input is configured in S2 SYSTEM SETUP  ANALOG INPUT and the actual values displayed in A2 METERING  ANALOG INPUT.This section contains the settings to configure the current demand monitoring elements. Included are a current demand level for each winding.TRANSFORMER OVERLOAD PICKUP: This setting identifies the level of transformer overload, where the pickup delay starts timing. The setting is expressed as a percentage of the transformer base MVA rating, and is normally set at or above the maximum rated MVA from the transformer nameplate. • XFMR OVERTEMP ALARM SIGNAL: Select any logic input that, when asserted, indicates the transformer cooling system has failed and an over-temperature condition exists. The logic input should be connected to the transformer winding temperature alarm contacts The tap changer failure element monitors the resistance seen by the tap changer monitoring circuit. The element produces an output signal when the tap changer position exceeds the maximum number of taps (set by the NUMBER OF TAP POSITIONS setpoint) by two. This signal can be used as an alarm or as a signal to change the setpoint group. A change in the setpoint group would be programmed through the FlexLogic™
