摘要
常规双母线接线GIS备用间隔扩建时,在母线拼接及耐压试验阶段需要将GIS全停后施工,对城市电网影响较大。结合武汉地区110 kV宝安变电站配电装置改造工程现场实际,对GIS进行了优化,应用了一种母线增设过渡模块的不停电扩建技术,通过可拆卸导体的在母线形成安全断口,保障了GIS在前期带电间隔非全停运行情况下的顺利扩建。
In the case of GIS(gas insulated switchgear)spare interval extension with conventional double bus connection,GIS needs to be completely shut down for construction in the stage of splicing and withstand voltage test,which has a great influence on urban power grid. This paper optimizes GIS according to the on-site practice of power distribution unit transformation project of 110 kV Baoan Substation in Wuhan,and also applies an extension technology without power outage to add transition module on bus. Finally,a safe fracture is formed in the bus with removable conductors to ensure the smooth extension of GIS under the condition of non-complete shutdown at the early live interval.
