Because the traditional microcomputer protection protects the logical design complex imperfect, the procedure development efficiency is bad, the design demand and the actual scene relation not close, as well as cannot satisfy the request to the protection openness and the compatibility. Therefore, in view of the above problems, this papers will visual logic programming theory is applied to the development of transformer protection logic program, it can significantly reduce labor and increase developer productivity, reduced protection programming in the human error factor. This paper focuses on the 35kV transformer protection logic programming implementations design by visual logic programming platform. First of all, through theory of voltage transformer protection research and analysis. Proposed based visualization platform for transformer protection functional requirements and research priorities . In this foundation, introduction visualization protection logic programmable platform meaning, composition as well as realization principle. Provides a design method and operation, a verification platform for logic design of transformer protection. Visualization based on flexible to protect ideological and practical needs, complete the corresponding protection logic diagram drawing. Protection graphic visualization platform to build and compile the generated executable file. Finally , download the related hardware platform , and verify the amount of protection function. Experiments have shown that in the platform on the transformer protection, its motion characteristics and time features meet electrical safety requirements. Through this topic realizatio
