避けられない。The operation of the power supply device having the above configuration will be described. When a high-frequency current is supplied to the primary power supply line 3 and currents are supplied to the pair of primary power supply lines 3 in opposite directions as shown in FIG. 4, the tip of the internal magnetic core 14 a in FIG. A magnetic path is formed between the first magnetic core and the outer magnetic cores 14b. When the power supply line is provided on the rail 1 provided on the side surface of the traveling route as in the present embodiment, a change in the distance X between the rail 1 and the secondary coil 14 due to the bending or branching of the route is inevitable. When this distance X approaches a predetermined value or less,
The rail 1 and the secondary coil 1 are formed by the magnetic shielding action of a conductor having no ferromagnetism such as aluminum which constitutes the rail 1.
The magnetic flux between the internal magnetic core 14a and the external magnetic core 14b concentrates in the space between the magnetic cores 4 and 4, the magnetic resistance increases, and the inductance of the secondary coil decreases. Will change. As a result, the difference between the frequency of the high-frequency current on the primary side and the frequency of the high-frequency current increases, and a reduction in transmission efficiency cannot be avoided.

る。On the other hand, in the case of FIG. 4B, even if the distance X becomes close to the predetermined value or less,
Since a magnetic path is formed on the surface of the rail 1 via the ferromagnetic plate 4 having a small magnetic resistance, the magnetic path acts to increase the inductance on the secondary side. As a result, the above-described reduction in inductance due to the presence of the rail 1 made of a conductive material is compensated for, and the change in the resonance frequency on the secondary side is suppressed.

ができるという長所がある。FIGS. 5A and 5B show the measurement results of the change in the inductance of the secondary coil due to the change in the distance between the tip of the inner magnetic core 14a and the outer magnetic core 14b and the rail 1 in FIGS. As shown. That is, as a result of measuring the resonance frequency of the resonance circuit in which the capacitor having the capacitance C is connected to the winding 15 constituting the secondary coil, as shown in FIG. While the resonance frequency has changed greatly,
In the case of (b), a magnetic path having a small magnetic resistance is formed due to the presence of the ferromagnetic plate 4, so that a change in the resonance frequency due to a change in the distance X is small. As described above, by suppressing the change in the inductance on the secondary side to a minimum irrespective of the change in the distance X, it is possible to maintain the resonance state of the secondary side with respect to the primary feeder line 3 and increase the transmission efficiency. In this embodiment, the frequency variation was 6% in the case of FIG. 4A, whereas the frequency variation was 2% in the case of FIG. 4B. . In addition, the stainless steel used in the present invention has better workability than ferrite as a general magnetic material, and is easily processed into a required shape according to various installation conditions such as the shape of the rail 1. can do. Further, stainless steel has an advantage that it has excellent weather resistance and can be procured at a lower cost than ferrite.

勿論である。As a result of obtaining good transmission efficiency irrespective of the distance X, it is suitably used particularly when a power supply line is provided on a rail provided on the side surface of the traveling route, and the rail is formed by bending or branching the route. Stable power supply can be performed regardless of a change in the distance to the vehicle (more specifically, a change in the distance between the rail-side power supply line and the vehicle-side secondary coil).
The above effect can be obtained only when the thickness of the ferromagnetic plate 4 is slightly larger than the depth at which the magnetic flux of the frequency can penetrate according to the frequency of the high-frequency current flowing through the primary feeder. At a frequency of 10 KHz of the high-frequency current, SU
When S430 is used, the necessary penetration depth of the ferromagnetic material 4 is about 0.15 mm. As a result of the experiment, a thickness of 0.3

Since the ferromagnetic plate is provided on the surface of the track, even if the magnetic flux is concentrated in the space between the track and the vehicle due to the change in the distance between the primary side and the secondary side due to the running of the vehicle, this area , It is possible to correct the decrease in inductance due to the concentration of the magnetic flux, so that a change in the resonance frequency on the secondary side can be suppressed and good transmission efficiency can be maintained. Also, since the system is insensitive to changes in the resonance frequency, not very high accuracy is required for rail installation that affects the distance between the primary side and the secondary side, and thus the installation cost can be reduced. . Further, the efficiency of the magnetic coupling between the primary side and the secondary side is improved, so that the current in the primary feeder line required to supply the same power is reduced, and therefore, the power transmission loss in the primary feeder line is reduced. be able to.
