Abstract

GIL case temperature rise is an important indicator of GIL operation.National standards stipulate that the GIL case temperature during operation cannot exceed 70 ℃.In order to verify the requirements of the temperature rise of the UHV GIL in the actual live environment

this paper combines the development and evaluation of the UHV GIL of the Sutong project to carry out the test of the UHV GIL case temperature rise and live under actual environmental conditions

and obtained the law that the maximum temperature of the GIL casing and the temperature rise of the case change with the ambient temperature over a long period of time under severe environmental conditions

the reasons for the temperature rise differences under the type test and live test conditions are compared and analyzed

and the GIL operation and maintenance recommended measures for the Sutong project are proposed.The research results show that the maximum temperature of the GIL case is 65.58℃（ambient temperature 36.15℃）.The consideration of reflective materials in the GIL units in the installation area of the north and south terminals of the Sutong project can reduce the heat absorption caused by solar radiation and ensure the safe and reliable operation of the GIL.
