同时也验证了设计原则和仿真分析的正确性。

Abstract

The three post insulator is the core component of GIL. It is widely used in the GIL. The design of the threepost insulator with high performance and high reliability is the basis for the development of 550 kV EHV GIL prod-ucts. In this paper

based on the design experience of GIS

the basic principles of insulation strength and mechani-cal strength of three post insulators are summarized. On the foundation of this

a three post insulator structure is de-signed

and the insulation and mechanical properties of it are analyzed and simulated applying the finite elementmethod and verified by experiments. The results show that the designed three post insulators fully comply with the re-quirements of 550 kV GIL and verify the correctness of the design principles and simulation.
