The invention relates to a dynamic display system for the power failure area of a power distribution network. The dynamic display system is characterized by being composed of a power failure switch, a data display module, a data processing module and an execution module, wherein the power failure switch is connected with the data display module through a conductive wire, the data display module is connected with the data processing module through a conductive wire, and the data processing module is connected with the execution module through a conductive wire. The dynamic display system disclosed by the invention is scientific and reasonable in structure, and the all-attribute functions of network distribution equipment is expanded through developing a network distribution mode data processing module; the system realizes the dynamic display of the fault power failure area according to the tele-metering and tele-signalling information of the network distribution equipment, and automatically provides a load transfer scheme according to a network distribution running mode. The dynamic display of the power failure area is capable of effectively increasing a fault processing level, rapidly judging the fault area, and much accurately directing fault processing; the system is a high-innovativeness dynamic display system for the power failure area of a power distribution network.
