Optimization Research on Seismic Safety Performance of UHV Porcelain Bushing Lightning Arrester Standardization
摘要
Abstract
1 Standardization research based on seismic performance of ultra high voltage (UHV) lightning arrester, an important electrical device in substation, is of great significance to improve its seismic protection ability and guarantee project construction period. Optimum design principle of earthquake resistance of the arrester is put forward, and numerical simulation is used to analyze and compare multiple schemes with theoretical analytical method. Then more reasonable structure parameters of porcelain bushing are confirmed. Finally, tests of domestic manufactured arresters on earthquake simulating vibration table verified that the test facility met seismic fortification requirements of ground motion peak acceleration 0.3g (PGA=0.3g). Research results confirmed standardized structure parameters and improved seismic protection capacity of UHV lightning arrester. They also provide technological direction for seismic protection optimization of other electrical equipment and strong safeguard for seismic safety of UHV substation.关键词
