Shake Table Test on UHV Standardization Lightning Arrester Installed with Shear-type Lead Dampers
摘要
Abstract
In order to improve the seismic safety of ultra high voltage (UHV) porcelain arrester. First, we proposed a structural design scheme of standard porcelain bushing for UHV lightning arrester based on the method of structural seismic optimization, thus the seismic safety factor was increased from original 1.68 in the 0.2 g (g=9.81 m/s2) horizontal seismic acceleration test to 1.73 of the new structure in the 0.3 g horizontal seismic acceleration test. Second, we simulated and analyzed the shock absorption of the UHV standardization lightning arrester with shear-type lead damper performance parameters. Last, we conducted the earthquake simulation shaking table tests of the UHV porcelain bushing with the shear-type lead dampers, whose model was got from the results of simulation analysis. Compared with non-damping in the white noise test structure, fundamental frequency of the damping structure were reduced by 2.76％～4.15％, and the seismic safety coefficients were 2.15 and 1.86, respectively, in the horizontal seismic acceleration 0.4 g and 0.5 g tests. The test results show that the method of structural optimization and shock absorption design can be used to improve the seismic performance of UHV lightning arrester, and installation of the shear-type lead dampers has hardly influences on the overall stiffness of the electrical equipment. The research results can provide references for seismic design and test of substation electrical equipment.关键词
