Abstract: Fixed support has the characteristics of overcoming the blind plate force for the dividing line of the flexible compensation section of a rigid gas-insulated transmission line (GIL), It also affects the safety and reliability of GIL operation simultaneously. This paper used Workbench to perform mechanical analysis on the fixed bracket, found the weak links, and optimized the structure to obtain a bracket structure that meets the needs. The results show that the structure and processing technology of the fixed support and GIL cylinder leg can meet the needs of certain projects after trial production, assembly and mechanical test of the fixed support and GIL shell.It also provides a reference basis for the fixed support design of long-distance GIL.
Key words: rigid gas-insulated transmission line; fixed support; structure optimization; experimental study
