The utility model discloses a uniform return current structure between a direct-current toothed rail traffic steel rail and a tooth rail. The uniform return current structure is invented to keep toothed rail potential and steel rail potential to be balance. According to the uniform return current structure, in a main track toothed rail section of a roadbed, a bridge and a tunnel, a descending leftsteel rail is connected with a descending toothed rail at certain intervals through first connecting cables, a descending right steel rail is connected with the descending toothed rail at certain intervals through second connecting cables, an ascending left steel rail is connected with an ascending toothed rail through third connecting cables at certain intervals, and an ascending right steel rail is connected with the ascending toothed rail through fourth connecting cables at certain intervals. Near a main track traction step-down hybrid substation, the descending left steel rail is connected with the descending toothed rail through a fifth connecting cable; the descending right steel rail is connected with the descending toothed rail through a sixth connecting cable; the ascending leftsteel rail is connected with the ascending toothed rail through a seventh connecting cable, the ascending right steel rail is connected with the ascending toothed rail through an eighth connecting cable, the descending right steel rail is connected with the ascending left steel rail through a second equal current cable, and the descending left steel rail is connected with a negative cabinet busbarin the track traction step-down hybrid substation through a negative return current cable.
