Vibration Properties of Two-Stage Magnetic-Valve Controllable Reactor

This paper investigates the vibration properties of a two-stage magnetic-valve controllable reactor (MCR) under different working conditions. The vibration mechanism of the MCR core is analyzed from the perspective of the conservation of mechanical and internal energy. The magnetomechanical coupling finite element method model of a 5400 var two-stage MCR is established. The core vibration of the two-stage MCR is analyzed at two operation conditions (with and without dc current) by using COMSOL. Finally, an experiment platform is built to test the vibration acceleration of the two-stage MCR core, and the calculation results are compared with the experimental ones.
