摘要
随着智能化变电站的建设,全光纤电流互感器得到广泛应用。由于其与常规电流互感器的工作原理不同,如何对其在现场进行有效的检验测试是一个难题。叙述了全光纤电流互感器的工作原理,并对其故障特征和检测项目进行分析。介绍了一种利用大电容放电原理制作的便携式现场测试装置,通过对上海110kV封周变电站全光纤电流互感器的现场试验,证明了测试原理与系统是有效的。
With the construction of intelligent substation,FOCT（fiber optical current transducer）has been widely used.For the working principle of FOCT is different from the conventional current transducer,the effective inspection and testing was a problem.The author introduces the working principle of FOCT,analysis of the fault feature and test items.And The author describes a portable testing device,which was made by the principle of large capacitor discharge.And the field test results in the FENGZHOU Transformer substation proved the test principle and system effectiveness.
