Abstract
The valve Reactor (VR) is an indispensable protective element within High Voltage Direct Current (HVDC) system converters, susceptible to malfunctions such as overheating and localized deformation under the conditions of ultra-high frequency and discontinuous operational excitation. This work provides a comprehensive review of the latest research findings on the electrical, thermal, and vibrational properties of VR. Initially, this work utilizes circuit models to analyze the constituent components of various VR types and their electromagnetic properties under actual working conditions, with a profound exploration of the insulation technologies involving epoxy resin and insulated silicon steel coatings. Subsequently, this work incorporates finite element analysis (FEA) on the basis of loss calculation models and conventional thermal circuit models to explain the temperature properties of VR from a multi-physics perspective. Furthermore, this work integrates mechanical calculation models with FEA models to elaborate on the vibrational properties of VR under practical excitations and discusses optimization measures. Finally, this work envisions the future development directions of VR from the perspectives of electrical, thermal, and vibrational properties, and proposes optimization suggestions, providing valuable references for the improvement of VR design and condition evaluation.
