Abstract  

Switching characteristics of the quick mechanism for the on-load tap-changer in oil environment were analyzed by using Particleworks based on a moving particle semi-implicit method. The working principle of the quick mechanism of on-load tap-changer was introduced, the mechanical structure of a quick mechanism of on-load tap-changer was designed, and the basis for dynamic calculation of the quick mechanism in the oil environment was provided. A dynamic simulation model in the oil environment was established for the quick mechanism of the on-load tap-changer, and switching characteristics were compared between the quick mechanism with and without transformer oil environment. The drive torque of the drive motor was required to be greater than 40 N·m. The influence of oil viscosity and energy storage spring stiffness on the switching characteristics of the fast mechanism was analyzed. The variation law of the oil resistance torque of the flywheel in the switching process of the fast mechanism under the oil environment was obtained, and the reasons for the variation and fluctuation of the resistance torque of the flywheel were revealed through the flow field analysis.
