摘　　要：归纳目前变电站二次设备改造方案,分析不同方案下常见设备的改造,综合现场施工和改造设备的特点,推荐“原屏改造”与“整屏更换”相结合,提出了预制电缆的“原屏改造”和拼接机柜的“整屏更换”的改进措施,采用自动对点系统改进系统接入工作,提高了改造效率,缩短了停电时间。The current renovation schemes of secondary equipment in substations are summarized,and the renovation of different schemes for common equipment is analyzed.Based on the characteristics of substation field construction and renovation equipment,the integrated scheme of"renovation-in-original-cabinet"and"whole-cabinet-replacement"is recommended,the improvement measures of"renovation-in-original-cabinet"for the prefabricated cables and"whole-cabinet-replacement"for splicing cabinets are put forward,and automatic information checking system is adopted to improve system access.These methods could improve the renovation efficiency and shorten the power cuts.
