The utility model discloses a GIS transformer station capable of rapidly identifying the position of a knife switch. The GIS substation comprises a plurality of GIS disconnecting links and a pluralityof disconnecting link box body connecting rods (2), the GIS disconnecting link comprises a disconnecting link body and a disconnecting link box body (1), the disconnecting link body is arranged in the disconnecting link box body (1), the two GIS disconnecting links are connected through a disconnecting link box body connecting rod (2), and the disconnecting link box body (1) and the disconnectinglink box body connecting rod (2) are respectively provided with a microstructure fluorescence reflection layer (3). The microstructure fluorescent reflective layer (3) comprises a microstructure layer (31) and a fluorescent reflective layer (32); and the fluorescence reflection colors of the microstructure fluorescence reflection layers (3) on the knife switch box body (1) and the knife switch box body connecting rod (2) are different. In the GIS substation, the box body of the GIS disconnecting link and the connecting rod of the disconnecting link box body are respectively provided with themicrostructure fluorescent reflective layer, so that the corresponding GIS disconnecting link can be quickly found and identified.
