Application of Base Isolation in High Voltage Electrical Equipment

Abstract eng:
The insulation member of high voltage electrical equipment is constitutive of porcelain insulator. The porcelain insulator is made by a kind of brittle material and it has a poor flexural performance. The porcelain insulator endures the considerable bending moment in earthquake, which causes the brittle destroy of porcelain insulator. Especially, the uncoordinated deformation increases the destruction on the connection of porcelain insulator and other materials. In order to solve the damage of high voltage electrical equipment in earthquake and discuss the feasibility of base isolation in high voltage electrical equipment, the seismic response analysis of isolation and non-isolation in high-voltage disconnector is studied in this thesis.
