Abstract

The 3D model of the oil-paper insulated transformer was constructed by SOLIDWORKS and simulated by Moldflow to optimize its vacuum-degassing technology. The number of the inside oil papers, the space of the adjacent two oil papers, the number and its distribution of the setting oil inlets are discussed in detail and the variation of the relevant formed air bubbles are analyzed. It reveals that the pouring process and the residual air bubbles are seriously influenced by the number and the space of the oil papers. In order to exhaust the inside air, the reserved oil inlets should be set symmetrically on the top of the transformer. Furthermore, the formation mechanism of the residual air bubbles is proposed.
