Wound-rotor type transformer and power source utilizing wound-rotor type transformer

An object of this invention is to enhance insulating properties between the terminals provided at both terminals of the secondary windings of the wound-rotor type transformer, and to drive the wound-rotor transformer safely, and the primary windings 110 , secondary windings M 1 , M 2 are mounted on the bobbins inserted with the bobbins. The terminal base 1 is provided at the side where the high tension terminals of the bobbins 102, 104 are disposed, and The first terminals S 1 , S 2 , S 3 and S 4 connected to the one terminals of the primary windings M 1 , M 2 are mounted on the terminal base 1 at the side where the high tension terminals are disposed. The second terminals A, B connected to the other terminals of the secondary windings M 1 , M 2 mounted on the bobbins 102, 104 are mounted at the side where the rearward low tension terminals are disposed at the side where the high tension terminals of the bobbins 102, 104 at a predetermined distance. The second terminals A, B are used as the ground terminals. The power source device is constructed to drive the lamps such as the cold cathode type-fluorescent lamps with the high tension output at the secondary side of the above-noted wound-rotor type transformer, and the primary windings 110 are connected to the AC signal output circuit, and the second terminals A, B are earthed, and the first terminals S 1 , S 2 , S 3 , S 4 are connected to the lamps such as the cold cathode type fluorescent lamps.
