Study on Magnetic Circuit Structure of Magnetic Valve Controllable Reactor Based on ANSYS

摘要

The core cross section area of magnetic valve controllable reactor has a reduced section. By changing the saturation degree of the cross section area, the capacity of the reactor can be changed. In this paper, focusing on a new type of magnetic valve controllable reactor prototype, the precise 2-D field-circuit coupling model of the prototype is established in the finite element analysis software ANSYS. Based on this model, the magnetic state within the core is studied under the combined effects of AC and DC. The theoretical analyses and simulation results show that the analyzed 2-D field-circuit coupling model can reflects the actual reactor transient electromagnetic process accurately.
