The invention provides an intelligent distribution network safety access platform and an implementation method thereof. The platform comprises a power distribution main station, a power distribution safety access gateway, a data isolation assembly and a power distribution terminal, a safety chip is embedded in the power distribution terminal. The power distribution main station, the data isolationassembly, the power distribution safety access gateway and the power distribution terminal are in communication connection in sequence. The power distribution main station initiates a connection request to the acquisition server through the data isolation assembly, the acquisition server sends the connection request to the power distribution terminal through the power distribution security accessgateway, and the power distribution security access gateway establishes connection with the power distribution terminal and performs security negotiation with the power distribution terminal. According to the platform, the construction and safety protection process of the distribution automation service system is accelerated, the stable transition of new and old distribution main stations and terminals is facilitated, the information safety protection level of a company production management area and a management information area is maintained on the basis of meeting the information safety protection requirement, and the safety of the distribution automation system is ensured.
