換える。The converter of the conventional tap changer is configured as described above,
For example, when reducing the voltage between the neutral point 50 and the output terminal 66, first, the movable contact 64b is connected to the tap 108, the movable contact 64a is connected to the tap 109, and the switching switch 65 is on the movable contact 64a side. The switching operation between the movable contacts 64a and 64b and the switching switch 65 brings about the state shown in FIG. When the voltage is further reduced from this state, the movable contact 64a is tapped.
While switching from 1 to tap 109, the second switching switch 59 is operated to move the movable contact b from the fixed contact 5 to the fixed contact 4, and after 64a is connected to 109, the switching switch 65 is moved to the 64a side. Switch to. At this time, the first switching switch 55 also operates in conjunction with the second switching switch 59, but the movable contact a is still connected to the fixed contact 2 as shown in FIG. Next, while switching the movable contact 64a from the auxiliary tap K to the tap 108, the auxiliary switching switch 67 is operated to move the movable contact c from the fixed contact 8 to the fixed contact 7.
After the movable contact 64b is connected to the tap 108, the switching switch 65 is switched to the movable contact 64b side.

記と全く逆の動作により実現できる。By these switching operations, the second rough tap winding 58 is separated from the main winding 51, and the winding connected in series between the neutral point 50 and the output terminal 66 is the main winding 51, the first winding. Only the coarse tap winding 54 and the fine tap winding 62 are provided. After that, the first coarse tap winding 54 can also be separated from the main winding 51 by the same switching operation. On the other hand, when the voltage is increased, it can be realized by the operation completely opposite to the above.

5,59 and one less auxiliary switch 67 than the number
When the number of coarse tap windings 54, 58 increases, the number of switching switches 55, 59 and auxiliary switching switches 67 correspondingly increases.
(2)各相に(1)項記載の切換スイツチ５５，５９および補
助切換スイツチ６７が必要であるため、三相器になると
その３倍の切換スイツチおよび補助切換スイツチが必要
となる。(2) Since the switching switches 55 and 59 and the auxiliary switching switch 67 described in the item (1) are required for each phase, the switching switch and the auxiliary switching switch three times as many as the three-phase device are required.
(3)第３図に示すようにブレードタイプの可動接点であ
