VARIABLE REACTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a single reactor device which can provide two sorts of different inductances which are both variable. SOLUTION: A coil 4 is wound around a coil frame 1 so that a cancel cylinder 7 is inserted into an interior of the coil frame 1 to be moved along a direction of an axial center of the coil frame. The coil 4 is connected at its one end with a first contactor 8 and at its intermediate part with a second contactor 9. The first and second contactors 8 and 9 are arranged along a movement stroke of the cancel cylinder 7 so that the first contactor 8 is connected to the second contactor 9 through the moved cancel cylinder 7. One of the sorts of inductances is found from the coil, while the other sort of inductance is found from such a state that the first and second contactors 8 and 9 are short- circuited by the cancel cylinder 7.
