摘要
针对电机保护类设备中的交流数据采集存在的保护时间和速度问题,从硬件和软件两方面进行了阐述.给出了隔离法和非隔离法两种数据采集硬件电路,在硬件电路基础上,阐述了交流量数据采集的方法,给出了采集到的瞬时值转换为有效值的计算公式.最后通过实验验证了所述方法的准确性.
In view of the protection time and speed of the AC data acquisition in the motor protection equipment,the paper studies that isolation method and no-isolation method are two acquisition hardware circuits from two aspects of hardware. and software. On the basis of the hardware circuit,the method of data acquisition is described and the calculation formula of the instantaneous value converted into effective value is given. At last the accuracy of the method is verified by experiments.
