摘　　要：在大型电站或变电站中,鉴于大型电力变压器与高压配电装置采用钢芯铝绞线等裸露软导体连接存在的弊端,通过设计L电厂525/230kV联络变压器与两侧GIS的连接方案,提出变压器双侧通过气体绝缘母线(GIL)直连的解决方案,并论述该方案涉及的相关电气技术问题。In the design of large power plants or substations,large power transformer and high-voltage power distribution devices are usually connected with soft bare conductors such as ACSR.However,the entire area will be very large for the longer length of the transformer casing and the requirement for safety distances.In addition,soft bare conductors are easily affected by the environment,resulting in potential safety hazards in power operation.In this paper,through the connection design of 525/230 kV interconnecting transformer and GIS on both sides in L power plant,the solution of the direct connection of the two sides of the transformer through the gas insulated line is proposed,and the relevant electrical technical problems involved in the scheme are demonstrated.
