Abstract

In recent years, China 's frequent earthquakes have caused serious damage to power facilities, seriously endangering people 's property safety and social stability. As the core component of the ultra-high voltage transmission project, the ultra-high voltage substation will cause huge losses to the society and the national economy once it is destroyed in the earthquake. The increase in equipment structure size caused by high altitude further enhances the seismic vulnerability of electrical equipment in the ultra-high voltage substation. To ensure the safety of the 110kV capacitor equipment used in a high-altitude ultra-high voltage substation project during earthquakes, the seismic response of the 110kV capacitor in the ultrahigh voltage substation located in a high seismic intensity area with a horizontal acceleration of 9 degrees was calculated based on a 0.4g acceleration level, and the structural strength was reasonably determined. The analysis of 110kV capacitors mainly includes two parts: (1) capacitor modal analysis; (2) The seismic performance analysis of the capacitor structure adopts the seismic acceleration response spectrum to analyze the seismic response of the capacitor, and provides performance judgment.
