Description

technical field [0001] The invention relates to the technical field of anti-seismic power transmission equipment, in particular to an anti-seismic high-voltage capacitor bank for ultra-high voltage direct current transmission engineering. Background technique [0002] UHVDC transmission refers to power transmission projects with voltage levels of ±800kV and above. A large number of high-voltage capacitor banks are needed in the converter station of UHVDC transmission projects. The rated voltage of AC high-voltage capacitor banks is 500kV and above. The rated voltage of the group is ±800kV and above. The converter station at the sending end of the UHVDC transmission project is usually built in remote areas such as Inner Mongolia and Xinjiang, which are also prone to earthquakes. Because the capacity of the capacitor bank is very large, the height of the capacitor bank is over 10m and the weight is over 40 tons. At present, the conventional anti-seismic technical measures of ...
