摘要
为满足使用罗柯线圈对超导导体的临界电流测试的需求,本文基于LabVIEW的同步采集与实时处理技术,设计了一套可搭配罗柯线圈的数字积分器,实现对罗柯线圈输出数据的采集与实时积分处理、显示以及数据回放等功能。该数字积分器相比模拟积分器具有易使用、误差低、低漂移等优点。实验测试结果表明该数字积分器的测试误差最大为0.8%,满足目前高温超导导体电流测试的要求。
To meet the testing requirements of critical circuits in superconductor using the Rogowski coil,a design of a digit⁃al integrator was presented based on the synchronous acquisition and real-time processing technology of LabVIEW.This integra⁃tor can be integrated with the Rogowski coil and enables the acquisition,real-time integration processing,displaying,and data playback of the output data of the Rogowski coil.Compared to analog integrators,the digital integrator has several advantages,including ease of use,low error,and low drift.The experimental test results show that the maximum test error of the digital inte⁃grator is 0.8%,which can meet the current test requirements of high-temperature superconducting conductors.
