例句与用法
- With the compensator , the accuracy of an 2 grade current transformers can be improved to less than the 0 . 2 grade standard at 100 % rating when the primary side current is changed from 2 % to 120 % of the rating
在实验中将准确度为2级的电流互感器经过补偿以后一次电流从额定值的5变化到120时，电流互感器的测量误差不超过一次电流额定值100时准确度为0 . 2级的测量标准。 - The author has finished the following several jobs in core of the centre : 1 ) the active compensation method based on bang - bang control was put forward to realize the wide range current transformer . the method converts the complex statement space to i / o description by the two - stage current transformer . with the compensation method , the accuracy of 0 . 2 grade current transformer can be improved to less than the 0 . 1 grade standard at 100 % rating when the primary side current is changed from 2 % to 120 % of the rating
围绕这一工作核心，作者完成了以下几项工作： ( 1 )以实现宽量程电流互感器为目标，提出了基于bang - bang控制的有源补偿方法，采用双级电流互感器，将复杂的状态控制分量转化为偏差控制，该方法结构简单，调试方便，有源补偿器输出电流小，可以将0 . 2级的电流互感器经过补偿后提高到一次电流从额定值的2变化到120时，测量误差不超过一次电流额定值100时准确度为0 . 1级的测量标准。
