Abstract:Transformer oil is easily polluted by metal particles. Once the metal particles accumulate in the oil channel, the insulation performance of the equipment will be greatly reduced. In this paper, an oil circulation device was built and the accumulation characteristics of free metal particles in flowing transformer oil were carried out under uniform and non-uniform electric field. The images of particle accumulation process were captured by a high-speed camera. Simultaneously, we analysed the force conditions of… Show more
