Abstract

High-voltage electric equipment in substation has high vulnerability during earthquakes. In order to investigate the applicability of isolation technology in UHV electric equipments, two finite element models of 1 000 kV arrester with and without isolation layer are established by ANSYS. And the dynamic time-history analysis using these two models are carried out by inputting earthquake waves. The results show that the arrester with base isolation has lower frequency. And its top displacement response, acceleration response, bending stress of porcelain bushings all have different degrees of reduction compared to those of arrester without base isolation. These conclusions have verified the effectiveness of the isolation system, and have provided a basis for the practical application of isolation technology in UHV electric equipments.

Key words
