FIG. 9 is a perspective view of a power receiver b shown in Japanese Patent No. 969. The power receiver b is located below the leading vehicle of a train (train) not shown and in front of the first axle of the leading vehicle (the first axle (wheel) in the traveling direction of the vehicle). The rail R on which the train runs is provided so as to face the rail R at a predetermined interval.

る。In the power receiver b having the above structure, when an ATC signal (a train control signal consisting of a reciprocating current) flows through one rail, the first axle and the other rail, the ATC signal vertically surrounds the rail in the longitudinal direction. The magnetic flux Φs of the alternating magnetic field is generated in the plane. The iron core 10 of the power receiver b collects the magnetic flux in the periphery and links it with the coil C to induce a signal voltage. The induced signal voltage is processed by an ATC receiver (ATC onboard device) (not shown) and used for train control.

.PHI.NO represents the leakage flux of the motor and is linked to the coil C in the horizontal plane. When this alternating magnetic field reaches the pair of left and right power receivers b, b, the magnetic field is not always symmetrical, and therefore the canceling effect by the series connection of both power receivers b, b in the opposite direction cannot be sufficiently obtained. , There is a risk that the noise level of the ATC receiver may be exceeded.

の間隔を保ちながら対向して設けられている。The power receiver a is located under the leading vehicle of a train (train) not shown and before the first axle (wheel) of the leading vehicle, and has a predetermined distance from the rail R on which the train runs. It is installed facing each other.

きる。The power receiver a is composed of a rod-shaped iron core 1 extending in a direction orthogonal to the longitudinal direction of the rail R, and a coil C wound around a central portion 1a of the iron core 1. The iron core 1 is bent downward on both longitudinal ends 1b and 1c, that is, toward the rail R side.
The shape of this bend is determined so as to follow the magnetic flux Φs due to the alternating magnetic field described later. Therefore, the bent shape is not limited to the trapezoidal shape shown in FIG. 1 and may be an arc shape.

The coils C, C of the pair of left and right power receivers a, a (the other rail-side power receiver is not shown) are connected in series in opposite polarities so that the output voltages are added.

いられる。In the power receiver a having the above structure, when an ATC signal (reciprocating current) flows through one rail, the first axle, and the other rail, the ATC signal causes an alternating magnetic field in a vertical plane surrounding the longitudinal direction of the rail. Magnetic flux Φs is generated. The iron core 1 of the power receiver a collects the magnetic flux around the coil C
To induce a signal voltage. The induced signal voltage is processed by an ATC receiver (not shown) and used for train control.

範囲内である。In FIG. 1, ΦNO represents the leakage flux of the train motor and is linked to the coil C in the horizontal plane. When this alternating magnetic field reaches the pair of left and right power receivers a and a, when the magnetic fields are symmetrical, they are canceled by the canceling effect due to the series connection of both power receivers a and a in the opposite direction. Also, there is a slight imbalance on the left and right, and that amount is added as noise to the ATC receiver, but this noise is usually within the allowable range of the ATC receiver.

できる。By the way, the iron core 1 of the power receiver a according to the present invention
Since both ends 1b and 1c are bent and follow the magnetic flux Φs of the ATC signal, the number of links with respect to the magnetic flux Φs can be increased and the received signal voltage can be increased.
When the iron core 1 is bent, an increase of 1 dB or more can be expected in the analysis using the finite element method as compared with the conventional linear iron core 10 of FIG. Therefore, the motor leakage flux Φs
Even if the noise due to noise increases, the original reception level of the ATC signal is high, so that the influence of noise can be reduced.
