A distribution network data transmission network and dispatching data network capable of performing data interaction comprises a regulation and control master station end, a local dispatching data network access network, a regulation and control substation end, a distribution and regulation master station end, a distribution network data transmission network, a distribution and regulation substation end and a safety isolation device, wherein the regulation and control master station end is connected with the regulation and control substation end through the local dispatching data network access network, the distribution and regulation master station end is connected with the distribution and regulation substation end through the distribution network data transmission network, and the regulation and control master station end is connected with the distribution and regulation master station end through the safety isolation device. On the basis that an original structure of the distribution network data transmission network and a dispatching data network is not damaged, the two networks are interconnected through the safety isolation device on the level of switches of the two system master station ends, interactive transmission of information is achieved, and the distribution network data transmission network and dispatching data network has the advantages of being simple, easy to implement and capable of saving transformation cost.
