Abstract：Research purposes ： Due to the outstanding advantages， overhead rigid catenary has become the first selection of overhead flow method in subway tunnels in our country. Guangzhou metro line 2 for more than ten years of operating results show that there are still some technical problems in the overhead rigid catenary system， such as the abnormal abrasion of pantograph - catenary， the insulation joint arc， central anchor knot in busbar lifting abnormal amount，etc. In order to solve and improve these problems in the operation，prolong the life of rigid catenary system and ensure operational security and stability，carry out a targeted design，modify and optimize the rigid suspension of existing lines.
Research conclusions: ( 1 ) Carbon pantograph slide abnormal abrasion is closely related to these factors， such as uneven distribution of catenary stagger value， the structure of the pantograph， weight of pantograph， carbon plate material quality，pantograph take larger current and serious vibration ； insulating the anchor segment joints arc is related to that pantograph slide carbon board can't keep parallel to the rail surface and pantograph - catenary interface is unbuffered rigid contact; the way that central anchor knot setting in between the two anchor point worsens pantograph - catenary relation. (2) Overhead rigid catenary system layout uses double broken line scheme to improve the pantograph -catenary abnormal abrasion problem， uses new type of rigid suspension elastic device increase system flexibility ； central anchor knot is installed in the middle of the anchor segment suspension point positioning to improve busbar height anomaly. (3) The research results can be applied to the design， construction， renovation and operation practice of urban and regional rail transit engineering，with strong reference and guiding significance.
