摘要
双母线接线的GIS设备扩建时,由于设备结构的特点,会存在停电时间长、影响范围大,进而降低电网安全运行可靠性的问题。从增强电网运行可靠性、减少停电范围的角度出发,对220 kV双母接线GIS非全停电扩建技术方案进行研究,并以律字220 kV变电站为例,提出具体的解决方案。
When the GIS equipment with double bus connection is expanded,due to the characteristics of the equipment structure,there will be the problems of long power outage time and large infl uence range,thus reducing the reliability of the safe operation of the power grid.In this paper,from the point of view of enhancing the reliability of power grid operation and reducing the power outage range,the technical scheme of partial blackout expansion of 220 kV double bus connection GIS is studied,and the concrete solution is put forward by taking the legal word 220 kV substation as an example.
