Simulation Analysis of Terminal Force of UHV Main Equipment

In this paper, the key stress part of main equipment of the UHV engineering is screened and determined firstly based on principles such as equipment importance, distance away from main equipment, load strength and equipment dimensions; and then, the influence of upper crossing line and down-lead on stress of UHV DC main equipment terminal is taken into consideration, and simulation models of terminal stress of two types of typical key main equipment, i.e. cross line - down-lead and herringbone down-lead are established; next, the comparative analysis between numerical simulation result and test result of herringbone down-lead is conducted to verify correctness of simulation model and test method in this paper.
