きく効率の五い集電が行えないという欠点があった。In general, non-contact current collectors for secondary levitation trains that utilize superconducting magnetic repulsion collect power through multiple current-collecting induction coils placed on the train facing the ground coil. ing. Normally, current collecting induction coils interlink with spatial harmonic magnetic flux, but this spatial harmonic magnetic flux differs in magnitude at each point in the train's traveling direction. However, since the number of turns of each current collection induction coil is the same, the weight of the induction coil is large relative to the collected power, and the reactance is large, making it impossible to collect current efficiently.

In other words, the induced voltage of the induction coil of the superconducting magnetic levitation railway spatial harmonic current collection type on-board power source device is the sum of multiple harmonics as shown in equation (1), so this induced voltage The number of turns of the induction coil is changed by taking advantage of the fact that the position of the induction coil varies depending on the position of the train. In other words, by using an induction coil with a large number of turns in areas where the induced voltage is high and an induction coil with a small number of turns in areas where the induced voltage is low, the weight of the induction coil with respect to the assembled power can be balanced and efficient current collection can be achieved. This is what I decided to do.

The induced voltages differ greatly at the positions of the induction coils 1 to 5. Therefore, in this embodiment, the number of turns of the induction coils 1 and 2, which have a relatively large induced voltage, is increased, and the number of turns of the induction coils 3 and 4, which have a small induced voltage, is decreased.

If we use the present invention to increase the number of turns in areas where the induced voltage is high and reduce the number of turns in areas where the induced voltage is low, the relationship between the induced voltage and the train speed will be as shown by the solid line Y in Figure 3, More power can be collected with the same induction coil weight. For example, 5g1
In the figure, when the number of turns of induction coils 1 and 2 is increased by 50% and the number of turns of induction coils 3 and 4 is halved - compared to the case of induction coils with the same number of turns, the induced voltage is approximately The efficiency was improved by 13%.
