摘要:性能校验是研究新型电流互感器的重点,针对新型电流互感器输出模拟电压小信号和数字信号的特点,依据IEC60044-8标准,建立了基于虚拟仪器开发平台Labview的电流互感器校验系统,并应用该校验系统分析了作者所研制的混合式光学电流互感器的比值误差、相位误差以及温度特性。校验分析结果表明,该电流互感器达到了IEC标准规定的0.2级要求;同时还表明方便、灵活和多功能的虚拟仪器技术加快了新型电流互感器的研发进度。
The performance calibration is the focal point in the development of novel current transformer. According to the feature of the novel current transformers that small analog voltage signals and digital signals will be output and based on the standard of IEC 60044-8, a current transformer calibration system based on the development platform of virtual instrument Labview is established, and the ratio error, phase error and temperature characteristic of the hybrid optical current transformer developed by the authors are analyzed by this calibration system. The results of calibration and analysis show that the developed current transformer can achieve 0.2 class specified by IEC standard, at the same time, it is indicated that the convenient, flexible virtual instrument technology which possesses multi-functions can speed up the development of novel current transformer.
