Anti-seismic performance is very important to high voltage switchgear. Using power spectrum density (PSD) method of random vibration module of ANSYS software, the mechanical strength of 1 100 kV HGIS in Nanyang substation was computed and analyzed under the condition of 0.3 g horizontal ground acceleration or 0.15 g vertical acceleration. The results show that 1 100 kV HGIS in Nanyang substation can withstand these two earthquake intensities and still have a large margin. Source
