摘要
在电力系统中越来越多大变比、高等级电压、额定大负载、GIS式、套管式电流互感器等被广泛应。目前,主要采用传统法、间接法的负荷外推法和互易法对电流互感器检测。本文阐述了以上方法的原理及其误差检测方法和实施步骤,并利用上述方法对现场的0.2 S级电力电流互感器进行检测,把测试误差数据做成曲线图进行比对分析研究,从而对现场检测技术的可靠性做出评估和分析。
In the power system more and more high ratio, high voltage, large rated load, GIS, bushing type current transformer is widely. At present, mainly using the traditional method, detecting load extrapolation and reciprocity method of indirect method of current transformer. In this paper, the principle of the method and its error detection method and implementation steps are described, and to detect the 0.2 S level in current transformer using the above method, the test data for error curve analysis research and comparison, which makes the evaluation and analysis of reliability of scene detection technology.
