摘要

In this paper the final results of basic research regarding the ageing process of insulations due to partial discharge (PD) activity under different thermal conditions are reported. According to the IEC publication 792-1 (IEC 1985 IEC Report Publication 792-1), the effects of a direct interaction between PD and temperature on material performance has been studied. We used, a simple electrode system with a flat cavity and an epoxy resin widely employed in high-voltage insulation apparatus to perform lifetime tests. On the basis of a previously performed analysis of the ageing mechanisms taking place in different materials, simple phenomenological life models are proposed in this work, giving a new approach to the problem that appears to be a useful tool for future application on electrical components. For this purpose, first the interaction between the temperature and PD was modelled, then a suitable PD quantity, depending on the energy wasted in the specimen during the ageing, was chosen to be assumed as a stress function in the inverse power law.
