分析10kV零序电流互感器特性及测试方法

摘要

10kV配电网采用中性点经小电阻接地的方式在我国投入运行的时间并不是很长，应用的范围也不是非常的广泛，有许多问题有待深入的探讨解决。对零序电流互感器正确的选型安装等方面进行研究，可以有效改善系统运行维护技术，能够有效的提高电网的运行效益。本文将对10kV零序电流互感特性及测试方法进行探究，避免保护误动作的发生，以保证系统安全运行。%The 10kVpower distribution network with neutral point by means of small resistance grounding in our country investment running time is not very long,the scope of application is not very widely, there are many problems to be deeply to solve.The correct selection and installation of the zero sequence current transformer can effectively improve the system operation and maintenance technology,which can effectively improve the operation efficiency of the power grid. In this paper,the characteristics and testing methods of 10kV sequence current mutual inductor are explored to avoid the occurrence of false action, so as to ensure the safe operation of the system.
