Magnetic Valve Controllable Reactor Magnetic Circuit Structure Based On ANSYS

In this thesis, the main structure, working principle and operating status of magnetic valve controllable reactor (MCR) are studied. Use the finite element analysis software ANSYS build a 3D structure model of MCR and make a theoretical analysis and methmatical derivation. Then, analyzes the magnetic cuicuit properties, loss properties and temperature rise properties of MCR.The magnetic distribution and the size of magnetic flux density in MCR can affect its loss directly. The losses will ultimately lead to temperature rise inside the reactor. These will not only reduce its efficiency, waste of energy, but will also lead insulation aging, endangering the safety and stable operation of the reactor. If a new design and improvements of MCR’s magnetic structure can be worked out, the-operation performance can be improved, the design cycles and cost can be reduced and MCR’s strengths can be spreaded.To this end, this thesis studies the various factors that affect the nature of the magnetic circuit to explore the principles and methods of magnetic circuit design. Based on this method, contrapose MCR’s large loss and high temperature rise, a new magnetic cuicuit structure is proposed.Then, analyze the relationship among structure, properties of MCR and deduce the inter influence mechanism among its material permeability, core diameter and small cross-sectional area. Last, propose an universal optimal design method. Proved by the theoretical analysis and simulation of new structure, the design method can greatly reduce its loss and temperature rise and satisfy the engineering needs.
