Earthquake-resistant high-voltage capacitor bank for extra-high-voltage direct-current transmission project

The invention provides an anti-seismic high-voltage capacitor bank for an extra-high voltage direct current transmission project, which comprises a high-voltage tower and a low-voltage tower, the high-voltage tower and the low-voltage tower comprise a plurality of capacitor frame layers, each capacitor frame layer comprises a frame and a plurality of capacitor units, and each frame comprises six load-bearing channel steels and four vertical steel pipes. The frame is of a rectangular frame structure, the load-bearing channel steel forms a main body of the rectangular frame structure, the steel pipes are arranged at four corners of the rectangular frame structure, the capacitor units are installed on the load-bearing channel steel, and the capacitor frame layers are connected through interlayer composite post insulators. And the interlayer composite post insulators are connected with the steel pipes of the upper and lower capacitor frame layers. According to the invention, the problem that a high-voltage capaci
