The Influence Study on X-ray Irradiation for the Transformer Insulating Oil

In order to understand the X-ray influence for the insulating oil of transformer in charged that is easy to determine the application area of the X-ray digital radiography system, it is proposed the research for the insulating oil of transformer in charged by the irradiation of the fixed X-ray energy in this paper. The portable high frequency X-ray machine is utilized to irradiate for the different oil quality and states of the study in charged. The experimental results demonstrate that H2 content of dissolved gas analysis and corona inception voltage of transformer insulating oil will be respectively increased and reduced by the irradiation of the portable high X-ray machine on the highest energy. And the extent of the increased H2 content and decreased corona inception voltage are all determined by the different transformer oil quality and states, the irradiation time of the X-ray.
