Radial grounding electrode with multiple current dispersing arm

The utility model discloses a radial grounding electrode with multiple current dispersing arms. The radial grounding electrode comprises a quadrilateral electrode which is formed by connecting an a-edge electrode (1), a b-edge electrode (2), a c-edge electrode (3) and a d-edge electrode (4) end to end in sequence, wherein four corners of the quadrilateral electrode are right angles, four vertexes are respectively welded with two current dispersing arms (5), and the current dispersing arms (5) and the quadrilateral electrode are arranged on the same plane. According to the radial grounding electrode with the multiple current dispersing arms, the four vertexes of the quadrilateral electrode are respectively welded with two current dispersing arms, an included angle between two current dispersing arms on the same vertex is 60 degrees, and an included angle between one of the current dispersing arms and a horizontal straight line or a vertical line is 15 degrees; the current increase reduction speed is fast under
