Numerical Analysis of Electric Field of Insulation Structure at Winding End of Power Transformer Based on Contact Finite Element Method
摘要
Statistics of power equipment operation faults show that the damage of insulation structure is one of the main causes of transformer faults. Transformers are widely used in power plants, substations and entire transmission and distribution networks in power systems. During transportation, power transformers may suffer from collision or external short circuit fault, which may cause winding looseness and deformation fault. If we can focus on the characteristics of the fault state of disconnection and remove it in time when the distribution line is disconnected, the difficulty of fault detection can be reduced. For the insulation structure, because of the complexity of the electric field distribution between the coils, especially at the end of the coil, the numerical analysis of the electric field distribution is of great significance to the design and optimization of the insulation structure. Based on the contact finite element method, this paper analyzes and studies the electric field value of the winding end insulation structure of power transformer, and further explores and analyzes the influencing factors of the electric field distribution of the winding end insulation structure.
