Research On Finite Element Simulation Of Typical Down Lead Of Transformer Substation

To calculate the stress status of equipment terminal exactly, this paper establishes the overall simulation models of two types of down lead structure systems, and compares them with the test result. The result shows that for cross line - down lead model and truss - down lead model, a relatively good effect has been obtained for both of them by using cable element to simulate conductor, and the error between the terminal stress simulation result and the test result is controlled within 15%, which means that the finite element simulation model of this paper is exact and reasonable.
