Electrified railway traction network voltage rise suppression processing system

The utility model relates to an electrified railway traction network voltage rise inhibition processing system which is characterized in that a train operation state identification system is installedon an uplink contact network or a downlink contact network and is connected to a control terminal to send train operation conditions and traction network voltage information; the traction network voltage limiting device and the uplink contact network or the downlink contact network form a series loop through the traction network voltage regulation and control unit; and the traction network voltage regulation and control unit is connected to the control terminal to receive the control information and regulate and control the traction network voltage limiting device. The traction network voltage is reduced by judging the running state of the train and selecting the reactors with different impedances to be connected in series in the subareas, and the traction network voltage reduction devicehas the advantages of bei
