The insulation performance of transformer oil is closely related to the stable operation of power system.It is inevitable that impurities such as moisture are mixed in transformer oil during actual operation.In order to explore the influencing mechanism of suspended water droplets on the insulation performance of transformer oil,finite element method is used to simulate the motion process and trajectory of water droplets in a simplified oil channel model in this paper.The interaction and phase transition process between oil and water phases in motion are simulated by the phase field method,and then the morphology and movement of the oil-water interface are described.The influence of electric field parameters and oil flow parameters on the deformation and coalescence of water droplets was systematically analyzed.The results indicate that water droplets in the oil channel will deform along the direction of the electric field and their deformation gradually increases with the increase of the electric field intensity,which suggests that the electric field intensity has an important impact on the degree of deformation of water droplets in the oil channel.In addition,under the same electric field intensity,the radius of water droplets is an important factor that leads to the length of aggregation time of water droplets.It is found that as the radius gradually increases,the aggregation time between water droplets becomes shorter.The research in this paper provides a theoretical basis for in-depth exploration of the characteristics and flow mechanism of oil-water two-phase flow,and is of great significance for improving the secure operation and efficiency of transformer.
