いる。Since the start of AC electrification and the practical use of thyristors, research into AC regeneration vehicles has begun.In AC regeneration vehicles, when applying the brakes, the motor for driving the electric vehicle acts as a full generator, causing the generation of This method obtains braking force by returning electricity to the power source. This method regenerates '1
If there is no load that can use the force effectively, braking force cannot be obtained, and the amount of regenerated electric power is also small, which negates the benefits. It was put into practical use only. In recent years, AC regenerative vehicles have been reconsidered from the perspective of stingray and energy resources.
However, the small amount of regenerated electricity is a major obstacle.

ンピーダンスが作用して小さい値となってしまう。In general, an AC regenerative vehicle transformer consists of a first winding that takes in power from the overhead wire, a second winding that supplies power to the electric car drive motor, and electrical equipment other than the drive motor inside the electric car. The third winding supplies power to auxiliary equipment, heating, service power sources such as food trucks, etc. (electrical equipment with a capacity of 10 to 30% of the second winding capacity). When power is on, power flows from the first winding 1 to the second winding as shown by arrow 49 in Figure 1.
It is supplied to the winding 2 and the third winding 3, respectively. This is,
During regenerative braking, power is supplied from the second winding 2 to the first winding 1 and the third winding 3, respectively, as shown by arrows c and 2 in FIG. The amount of electric power regenerated through the first winding 1 will be small due to the impedance of the overhead wires and the impedance of the substation if there are no powered vehicles nearby or if it is far from the substation. I end up.
また、従来の巻線配置は、第3巻線の電圧変動率を小さ
くするために、第3図のように第1巻線1と第3巻線3
を近接させて配置する構造としていた。In addition, in the conventional winding arrangement, in order to reduce the voltage fluctuation rate of the third winding, the first winding 1 and the third winding 3 are arranged as shown in FIG.
The structure was such that they were placed close together.
従って、回生ブレーキ時に第2巻線2から第3巻線3へ
の回生電力量が少ないという欠点があった。Therefore, there is a drawback that the amount of regenerated electric power transferred from the second winding 2 to the third winding 3 during regenerative braking is small.
本発明の目的は、第3巻線の電圧変動率を増加すること
なく、第2巻線から第3巻線への回生電力を増加させる
事のできる車両用変圧器の巻線配置4を提供するにある
。An object of the present invention is to provide a winding arrangement 4 for a vehicle transformer that can increase regenerative power from the second winding to the third winding without increasing the voltage fluctuation rate of the third winding. There is something to do.
本発明は、第3巻線の電圧変動高を増加させないために
、第1巻線と第3巻線を近接させ、かつ第2巻線から第
3巻線への回生電力を増加させるために、第2巻線と第
3巻線も近接させる必要があった。In order to prevent the voltage fluctuation height of the third winding from increasing, the present invention makes the first winding and the third winding close to each other, and to increase the regenerative power from the second winding to the third winding. , the second winding and the third winding also needed to be close to each other.
従って、第2巻線と第3巻線とを2分割し、第1巻線の
両側に第3巻線と第2巻線を順次配置することにより目
的を達成する。Therefore, the purpose is achieved by dividing the second winding and the third winding into two and sequentially arranging the third winding and the second winding on both sides of the first winding.

The third winding actance X3 and the resistance R3 of the third winding may be made smaller than the actance X2 and the resistance R2 of the second winding. In addition, in order to prevent the voltage fluctuation rate of the third winding from increasing, the first winding glue actance X1 and the resistance hole 11 of the first winding must be
And the sum of N3 and 几3 should not be increased. R1
, 几2゜R3 are generally very small compared to Xx, N2 + Xs, so the ability to control Xt, Xz, and Xs is advantageous. Just keep the size of the tab, Xt+Xa, as it is, and reduce N2 +Xs.
