RADISYS EXM-4工控卡件PLC

产品详细资料
•W1（3）NEUTRAL INST OC 1（2）PICKUP：输入中性电流水平（以继电器标称电流为单位），超过该水平，绕组1（3）中性瞬时过电流1元件将拾取并启动延迟定时器。•W1（3）空档INST OC 1（2）DELAY（延迟）：输入在元件工作之前，空档电流必须保持在拾取电平以上的时间。注：中性点瞬时过电流2元件的上述设定点信息和以下逻辑图相同。在745中，“接地”是指在变压器中性点和接地之间的CT中测量的电流。745具有两个接地输入，可以根据根据表3-2中的规则选择的变压器类型将其分配给三个绕组中的任何一个。显示并启用与绕组指定的接地输入相对应的接地过电流设置。本节包含配置接地过电流元件的设置。包括每个相关绕组的接地时间过电流，以及每个相关绕组两级接地瞬时过电流。•W1（3）接地时间OC拾取：输入接地电流水平（以继电器标称电流为单位），超过该水平，绕组1（3）的接地时间过电流元件将拾取并开始计时。
• W1(3) NEUTRAL INST OC 1(2) PICKUP: Enter the level of neutral current (in units of relay nominal current) above which the winding 1(3) neutral instantaneous overcurrent 1 element will pickup and start the delay timer. • W1(3) NEUTRAL INST OC 1(2) DELAY: Enter the time that the neutral current must remain above the pickup level before the element operates. Note The setpoint messages above and the following logic diagram are identical for the neutral instantaneous overcurrent 2 element.In the 745, “ground” refers to the current measured in a CT in the connection between the transformer neutral and ground. The 745 has two ground inputs which could be assigned to any of the three windings, based on the transformer type selected with respect to the rules in table 3-2. As the ground overcurrent settings corresponding to the winding-assigned ground inputs, are displayed and enabled. This section contains the settings to configure the ground overcurrent elements. Included are ground time overcurrents for each associated winding, and two levels of ground instantaneous overcurrent for each associated winding.• W1(3) GROUND TIME OC PICKUP: Enter the level of ground current (in units of relay nominal current) above which the winding 1(3) ground time overcurrent element will pickup and start timing.
