SF_6充气柜在城市220kV变电所的应用

Application of SF_6 Gas-insulated Switchboard to 220kV Urban Substation

介绍了SF6充气柜的特点,从接线及进出线的选择、平面布置的考虑和柜体基础的设计提出了SF6充气柜在220kV变电所应用中的设计方案以及要解决的问题。以220kV金桥变电所为例,说明了SF6充气柜在城市变电所应用的设计思路和要点。

This paper introduces the characteristics of SF6 gas-insulated switchboard,and presents the design scheme and problems in need of solvent in the application of SF6 gas-insulated switchboard to the 220 kV substations from the aspects of connection choice, in and out line choice,plain layout consideration and board foundation design. And then it analyses the design thought and main points of using SF6 gas-insulated switchboard in urban substations taking the 220 kV Jinqiao substation as an example.
