中文摘要:
      用于电流互感器准确度校验的标准电流互感器为铁磁式、多引线抽头结构,二次侧存在开路高压危险。在校验时需更换一次导线缠绕匝数和二次出线接线柱。基于罗氏线圈电子式互感器制造技术,通过高精度罗氏线圈和多量程控制系统方案设计,研制了0.05级罗氏线圈标准电流互感器,可满足从5~5 000 A不同量程额定一次电流校验要求。罗氏线圈标准电流互感器实现将一次电流信号转换为标准数字信号,具有无铁芯、质量轻、体积小等优势,同时,还具有高线性度、宽范围测量、频率响应范围宽及开放协议等特点,能够满足数字信号发展的电子互感器准确度校验要求。
英文摘要:
      The standard current transformer using for calibration of current transformer is ferromagnetic and multiple tap structure, which secondary side exists the high voltage danger when in open circuit. It is needed to change high side wire coils and secondary outlet terminal when measuring the accuracy of calibration. Based on the Rogowski coil electronic transformer technology, through high precision Rogowski coils and the design of multiscale control system, this paper developed the standard current transformer of 0.05 level by Rogowski coil, which can meet the accuracy calibration from 5 A 5000 A in different rated primary electricity flow. By using Rogowski coil and high precision digital multirange control system, it can convert current signal into standard digital signal. Rogowski coil has not iron core, and has the advantages such as light quality、small volume, meanwhile,it also has high linearity wide measuring range, wide frequency response range and have open protocols, and it can meet the development of digital signal electronic transformer calibration accuracy requirements.
