<p>PURPOSE:To facilitate the regulation of errors by adjusting a leakage reactnace to any value with proper rotation of a given number of auxiliary core inserted between windings, while miniaturizing the device doubling it as an electrostatic shield between the windings. CONSTITUTION:A primary winding 8 and a secondary winding 9 are wound around one leg of a main iron core. A given number of auxiliary cores 7 which are inserted between windings 8 and 9 are made large enough to shield the windings from each other. It has a hole at the center thereof to have both legs of the main iron core run through and cut off properly to match an iron piece with such a shape that the length of a clearance with the other leg can be changed continuously when it is rotated with the leg as axis. Thus, easier regulation of errors is accomplished by adjusting a leakage reactance with proper rotation of the iron core 7 while miniaturization of the device is possible by doubling it as an electrostatic shield between the windings.</p> |
