Abstract

In this paper, the CEL (Coupled Eulerian-Lagrangian) fluid-solid coupling simulation method is adopted to simulate the mechanical behavior and bubble pulsation evolution process of the transformer oil filled in the converter transformer when a high-energy discharge failure occurs in the on-load tap-changer of the converter transformer. The mechanical response of the tap changer and its solid structure is analyzed. Based on this, the compensation performance and strength of the pressure compensated expansion joint installed on the tap changer are evaluated.
