浅析智能变电站二次安装继电保护要点

Analysis on two points of relay protection for Smart Substation

随着时代的发展,我国在智能变电站建设上的投入力度越来越大,随着其数量的提升,继电保护工作也发生了极大改变。本文根据以往工作经验,对智能变电站二次安装继电保护现状进行总结,并从"投检修态"压板、软压板投退、光纤拔除、合并单元检修时二次安全措施的实施四方面,论述了智能变电站二次安装继电保护要点。

With the development of the times, China＇s investment in the construction of smart substations is increasing,with the increase of its number,relay protection has also undergone great changes. Based on the past work experience,this paper summarizes the eurrent situation of relay protection in secondary installation of intelligent substation, and discusses the key points of relay protection in secondary installation of intelligent substation from the following four aspects：pressing plate in service mode,soft pressing plate throwing back,optical fiber pulling out,and the implementation of secondary safety measures in combined unit maintenance.
