摘要

针对就地化智能电子设备(IED)在开关场无防护安装时面临的接地及抗干扰问题

介绍了传统变电站二次等电位地网的设计及IED的接地方法。分析了就地化IED在开关场无防护安装时需要面对的复杂电磁兼容环境和需要解决的具体问题

提出了分布式开关场二次等电位地网的设计思路。详细阐述了就地化IED及其外部线缆在开关场无防护安装时的接地方法、就地化IED增强抗干扰能力的设计方法。厂内试验结果验证了所提方法的可行性。

Abstract

Grounding and anti-interference are the key technical concerns in the unprotected field installation of intelligent electronic devices(IEDs)in switch yard. This paper introduces traditional designs of secondary equipotential grounding grid and IED grounding methods

analyzes the complicated Electromagnetic compatibility envi-ronments and relevant specific problems in the unprotected field installation of IEDs in switch yard

recommends-design ideas for the secondary equipotential grounding grid in distributed switch yard

elaborates on the grounding methods for field installed IEDs and external cables in the unprotected installation in switch yard and design ap-proaches for higher anti-interference ability in field installed IEDs. In-house experimental results have verified the feasibility of the proposed methods.
