摘要
探讨了超导线圈失超特性、失超检测的基本原理;提出了一种创新型的检测方法—电压差相位检测法。在此基础上,重点描述了在LabVIEW中的G语言编程环境下,基于电压差相位检测法设计出的失超检测系统,以及其在单机测试和NI开发平台中的测试结果,验证了电压相位差检测法的可行性、优越性。将该方法与已有的失超检测方法进行比较后,证明了本方法在检测精度、运行环境等方面优于现有方法,并且完全适用于超导电机和超导变压器。
This paper discussed the characteristics of quench and the basic principles of the quench detection for superconducting coil. A novel detection method called voltage differential phase detection method was proposed. In this case,we mainly designed the detecting system of quench based on this method in G programming language situation of Lab VIEW. In addition,the feasibility and superiority of voltage differential phase detection method were verified according to the results of stand- alone and NI platform test. After comparing this method with the existing quench detection method,it was proved that this method was superior to the traditional method in terms of the accuracy and operating environment as well as can applicable to superconducting motors transformers.
