In this article, in order to coordinate the field construction for the distribution-network overhead line test, according to the requirements of the actual working conditions, an experimental device for shift range of transmission lines is developed. Efforts are made to work out the overall scheme of the experimental device for shift range, including platform, tower and orbit;the platform is subject to the design as well as the stability-based checking and calculation;the experimental device’s transmission system is set up. The three-dimensional modeling software SolidWorks and the simulation software ADAMS are used to complete modeling and simulation of the experimental device for shift range of transmission lines;its displacement and speed are analyzed. Through a series of research on the experimental device’s driving speed, lateral offset and wheel-rail contact, the results show that the experimental device for shift range of transmission lines enjoys desirable function of shift range as well as stable and safe operation, which provides theoretical basis for improvement of experimental devices in the future.
