Effect of Modifier TMPTMA on Electrical Properties of Cured Epozy System for V.P.I. Resin
V.P.I. is the most advanced impregnation technology for the electrical machines that have been developed. With the rapid development of the electrical industry, demands of improving the properties of V.P.I. resins become higher and higher. It is of practical significance to investigate the effect of the modification of the epoxy resin TMPTMA on the cross-linking structure, the dc electrical resistivity and dielectric breakdown characteristics of the cured epoxide for V.P.I, insulation. This paper aims to explore the effect of TMPTMA concentration on the temperature dependence of the dc resistivity of the cured system and to study the dielectric breakdown behaviors of the cured systems with different TMPTMA concentrations. The modification of the epoxy resin by TMPTMA has been found to surely provide the possibility for improving the density of the cross-linking structures, electrical properties and thermal stability for V.P.I. resin based on the epoxy resin.
