摘要
电子式互感器作为智能变电站关键设备,以更安全、节能、环保的优点逐步取代传统的电磁式互感器,而电子互感器校验系统研究却相对滞后。本文简要介绍了电子互感器校验的工作原理和误差的定义,并根据IEC60044-8标准,分析得出了系统的11个误差来源所引起的不确定度,最后给出了尽可能消除这些误差的方法,为电子式互感器现场校验装置的研制提供了强有力的理论支持。
As the key equipment of the intelligent substation,electronic instrument transformer gradually replaces traditional electromagnetic transformer,with the advantages of more safer, more energyefficient,environmentally friendly, but the research on the electronic instrument transformer calibration system is lagging behind.This paper briefly introduces the working principle of elec tronic instrument transformer calibration and the definition of error, According to the standard IEC60044-8, analysis the uncertainty caused by the eleven error sources of the system.Finally, it gives some solutions to eliminate these errors as far as possible,provides the powerful theory support for the development of electronic instrument transformer calibration device.
