摘　　要：为了建立低压防窃电电流互感器质量评价体系,本文研究了新型低压防窃电成套电流互感器(CT)特性。通过研究防窃电结构特性和CT绝缘特性,推荐出优良的低压防窃电成套CT典型设计结构;通过研究CT伏安特性和误差特性,找出电测量特征和铁芯材料性能之间的对应关系,为低压防窃电成套CT的质量评价提供参考依据。检测方法依据相关国家标准进行,检测结果说明,低压防窃电成套CT的设计结构会严重影响绝缘特性;电测量特征与铁芯材料性能之间存在较为明显的对应关系。In order to establish the quality system of estimation, the characteristics of the new unitied low-voltage current transformer （ULCT） with the function of preventing electricity-stealing have been well studied in this paper. The typical designed structures of the ULCT are recommended based on the studies of electric largeny prevention structure and CT insulation chracteristcs, and the relationship between the electrometric features and performance of CT cores is established based on the studies of CT volt-ampere and error characteritics. All the detection methods are all followed with the national standards of China. The results of the detection show that the structures of the ULCT can influence baddly the insulation characteristics and there are strong relations between the electrometric features and performance of CT cores.
