Abstract

PURPOSE:To facilitate the work for connecting lead wire of a zero-phase-sequence current transformer used on leakage breaker and others by fixing a lead wire connecting device in a case and then leading a secondary winding as lead wire to soldering along a channel on a printed circuit substrate. CONSTITUTION:After fixing a zero-phase-sequence current transformer 1 used on leakage breaker and others in a case 2, a secondary winding 6 is led outside through a channel 8 arranged in the case 2. A hollow 9 is then provided on the outer periphery of a printed circuit substrate 4 with which the case 2 is fixed, a land 10 is formed further on the outer periphery of the hollow 9, and the secondary winding 6 led out of the channel 8 is led onto the land 10 to soldering 11 through the hollow 9 on the substrate 4. A signal detected on the zero-phase-sequence current transformer 1 is transmitted to the land 10 of the substrate 4 and then given to an electronic circuit 3, thereby facilitating the work for leading out the secondary winding 6 and preventing the lead wire and the secondary winding 6 from disconnection.
