摘　　要：为了保证供电可靠性,110 kV变电站均安装备自投装置;然而对于一些110 kV拉手环网的变电站,常规备自投将无法满足供电可靠性的要求。文章以淄博供电公司110 kV甲站、乙站之间新投运的2套远方备自投装置为例,分析了2站之间远方备自投功能的原理和实现方法,提出了图纸设计和装置动作逻辑之间冲突的问题,并基于此问题,给出了图纸设计以及备自投逻辑的改进方法。对于类似远方备自投装置的施工,具有较好的指导作用。In order to ensure the power supply reliability,the 110 kV substation of the regional power supply company must be equipped with automatic bus transfer equipment.However,for those substations which are hand in hand ring meshing wiring,conventional automatic bus transfer equipment cannot meet requirements.In this paper,two sets of remote backup devices newly put into operation between A and B 110 kV substations in local power supply company are taken as examples,to analyze the principle and realization method of remote backup device function.The problem of conflict between layout design and action logic are presented.Based on this question,improvement methods of the layout design and the device logic are given.This paper has a good guiding function for the construction of similar remote backup device.
