- Abstract
In this article, seismic and shock absorption experiments of ultra-high voltage (UHV) porcelain arrester is carried out to investigate a seismic withstand ability for UHV porcelain equipment. To ensure the seismic safety of UHV equipment, tensile and compressive cyclic loading tests of metal dampers for arrester were conducted. Test results showed that hysteresis curves are full, and energy dissipation characteristics are significant. The mechanical characteristics meet Wen constitutive model. The shaking table test found that the shock absorber increased damping ratio of arrester structure and extend the characteristic period of arrester, which improve the dynamic characteristics of the electrical equipment. Under seismic action, the metal plastic deformations in the damper dissipate seismic energy, which reduce stress and acceleration of arrester. The damper significantly inhibits seismic response to improve the UHV arrester seismic safety. In the 0.3g level earthquake, stresses of UHV arrester with dampers and without dampers were 26.56 Mpa and 43.28 Mpa respectively. The safety factor of damper-added arrester structure meets the requirements. This paper provides technical support for the ultra-high voltage electrical equipment applied in the high-intensity seismic zone.
