PURPOSE:To enable to regulate the inductance value of a reactor by inserting an adjustable impedance to the holes of fittings, supporting fittings and a base. CONSTITUTION:An insulator 9 inserted into the hole of intermediate supporting fittings 4, and a variable impedance 10 inserted into the hole of the fitting in parallel with the insulator 9 are provided. When a main magnetic flux phiby the current of the coil is passed to a closed circuit formed through the imped ance 10, a current I' is flowed by an induced voltage (e). The magnetic flux by the current becomes opposite to the flux phi' thereby regulating the inductance value irrespective of the coil even for an air core coil. |
