Installation and debugging of GIS equipment for the Shisanling Pumped-storage Power Plant

The equipment for the 220 kV switch station of Shisanling Pumped storage Power Plant is an ELK14 SF 6 GIS made by ABB Company in Switzerland. In accordance with the technical parameters, structural characteristics and installation requirements of GIS, some effective measures have been taken in the installation and debugging, such as using the transportation way of assembling the parts with partition; changing the fixing way of original GIS partition base; controlling strictly the butt errors of transformer and GIS; ensuring the environment clearance of working surface during installation; and protecting strictly the high pressure casing pipe from getting damp. With these measures, good effectiveness has been gained and the work of installation and debugging has been completed with high quality and efficiency.
