The invention provides a +/- 800 kV convertor station direct-current field high-voltage equipment mounting structure. The +/- 800 kV convertor station direct-current field high-voltage equipment mounting structure comprises a 800 kV grounded isolating switch base, high-voltage smoothing reactor bases and a 800 kV coupling capacitor bracket structure, wherein the 800 kV grounded isolating switch base comprises 800 kV ungrounded isolating switch bases, 800 kV single-point grounded isolating switch bases and 800 kV double-point grounded isolating switch bases; the 800 kV ungrounded isolating switch bases, the 800 kV single-point grounded isolating switch bases and the 800 kV double-point grounded isolating switch bases are distributed according to a V-shaped structure of which the opening faces the right; the high-voltage smoothing reactor bases are arranged on the opening side of the right-opening V-shaped structure; and the 800 kV coupling capacitor bracket structure is arranged parallel to the 800 kV double-point grounded isolating switch bases. By adoption of the +/- 800 kV convertor station direct-current field high-voltage equipment mounting structure provided by the invention,the excellent anti-seismic property of each electrical loop during a high-intensity earthquake can be ensured, the equipment bracket column top displacement acceleration amplification coefficient canmet the requirements of anti-seismic specifications for electric power facilities, and then the normal running requirements of electrical equipment can be met. Through the optimization of the direct-current field layout, the occupied land area can be reduced, and the safe distance can be kept after the electrical equipment is mounted in place.
