Analysis of Magnetic-Fluid-Thermal Coupling Simulation of Three-Phase Three-Dimensional Wound Core Dry-Type Transformer
摘要
Abstract
The manufacture and structure of the wound core transformer is different from the ordinary laminated core transformer,and the magnetic circuit and electromagnetic properties have their special characteristics.The coupling simulation model of electromagnetic,temperature and flow field of three-phase three-dimensional wound core dry transformer is established,the magnetic field and current of the transformer are simulated and analyzed,and the loss of the transformer is calculated under the corresponding state.The calculated loss is mapped to the temperature field and the fluid field,and the magnetic-fluid-thermal coupling of the transformer is simulated by Icepak software,and the impact of the clamp on the temperature distribution in a dry-type three-dimensional coil core transformer is examined.The result show that compared without the clamp,with the clamp increases the temperature of the transformer components.The coupling analysis of magnetic field,loss,heat dissipation and temperature rise of three-phase three-dimensional wound core transformer is of significance to the performance analysis,optimal design,operation and maintenance of transformer and the development of digital twin technology.关键词
