The invention discloses a plane arrangement optimize structure of a rigid contact system. The abrasion among bow nets at the rigid suspension section is reduced, and the non-uniform degree of the abrasion is reduced, so that the uniform abrasion of a pantograph carbon contact strip is achieved finally, the service life of the pantograph carbon contact strip is prolonged, and the purpose of reducing the replace and maintenance operation of the pantograph carbon contact strip is achieved. The plane arrangement optimize structure comprises anchoring sections formed by straight busbars (11) and curved busbars (12); the stagger values of all suspension points of the anchoring sections are arranged according to 2 to 5 mm/m constant change rate along a line; each anchoring section is bent once; and the suspension point where the highest stagger value of each anchoring section is positioned is arranged as a center anchoring joint (13).
