数据窗 meaning in English
data window
Examples
- Change setpoints from the data window
从数据窗即可修改设定值 - Control is often used on forms with controls that have varying lengths of data to present , like windows explorer , whose data panes contain information of varying widths at different times
控件常用于一类窗体，这类窗体上的控件所显示的数据长度可变，如windows资源管理器，它的数据窗格所包含的信息在不同的时间有不同的宽度。 - Applying relative arithmetic to all kinds of faults and calculating off - line , we can master time - distance relation chart for all kinds of faults . computation indicates : when transmission lines occur faults , the data window of protection algorithm consisting of prefault and postfault data at the same time has important significance . the following methods are useful to achieve the inverse time characteristic : calculating impedance by using flourier in a full cycle , calculating work voltage by using fault component , calculating the torque created by a phase comparator or a magnitude comparator
实际的计算表明：输电线路发生故障后，用故障前后的数据同时充满保护算法的数据窗，对于快速切除近区故障具有很重要的意义；同时利用故障前后的数据，下述方法可以比较好地实现距离保护的反时限特性：直接用全周傅里叶算法进行阻抗计算；采用工频变化量阻抗继电器进行工作电压的计算；采用转矩的思想进行转矩的计算。
