PURPOSE:To detect a spark discharge or the like without increasing the size and weight of a DC power source or causing a loss by winding the primary winding in a rectifying transformer core, further winding the secondary winding on the outside, and winding a spark discharge detecting winding at the other position of the core. CONSTITUTION:The primary winding P' is wound on a central leg 2 of a 3-leg core 1 of a transformer TR', the outside is treated with the prescribed insulation, and the secondary winding S' is wound. Further, a winding T for detecting a spark discharge or the like is wound on the side leg 3. The impedance between the windings P' and S' contains the impedance of a current limiting reactor. When a spark discharge occurs at the load side, a magnetic flux in the leg 3 is extremely reduced, thereby decreasing the induced voltage of the winding T. |
