摘要
阐述了目前常用的两线三变扩大外桥接线桥开关备自投方案。针对其存在的缺点,提出简单可行的改进方案,并对改进方案的优缺点进行分析。根据改进方案的逻辑原理,提出方案的实现方法,编写出实际工程应用的软件流程图。
This paper discusses the measurement of current auto-switch-on application of the external bridge breakers of the two incoming feeders and three transformers substation. Based on the disadvantages of current measurement, this paper discusses a simple but useful improved measurement and details its advantages and disadvantages. Based on the logic principles of the improved measurement, this paper also introduces how to realize it and draws the flow chart of the applicable program.
