High voltage DC transmission compact type earthing electrode

The utility model relates to a compact earthing electrode for high voltage and direct current transmission, comprising a terminal tower (1) of earthing electrode line, an earthing electrode line (2), a shunt frame (3) of earthing electrode, a current equalizing device (4), three shunt lines in different directions (5A, 5B, 5C), and three earthing electrodes (6, 7, 8), wherein, both ends of the earthing electrode line (2) are connected with the terminal tower (1) of earthing electrode line and the shunt frame (3) of earthing electrode respectively; the shunt frame (3) of earthing electrode is connected in series in the shunt lines (5A, 5B, 5C); the earthing electrodes (6, 7, 8) are earthing electrodes of internal loop, intermediate loop and external loop in order; the shunt lines (5A, 5B, 5C) are connected separately with the earthing electrodes (6, 7, 8). The utility model overcomes the disadvantages, such as large floor area in the prior earthing electrode, and has the advantages of reduction of location dif
