The AF transmission current i transmitted from the transmitter T flows in the direction of the arrow through the short circuit impedance Z B , and an induced voltage is generated in the loop coil l 1 and the loop coil l 2 , and the AF receiver R 1 and the AF receiver R 2 is operated, respectively, and orbital relays (not shown) connected to the AF receivers R 1 and R 2 are energized.

Since there is almost no loop coil, as shown in Figure 1,
By installing l 1 , l 2 , etc., one AF transmitter T can receive multiple powers, making it an extremely effective power receiving device for use in level crossing control. Furthermore, after the last train passes the power receiving point, the induced voltage returns within a relatively short distance, resulting in good resolution.

動作に至らしめるという危険がある。 However, with the recent modernization of railway vehicles, thyristor control devices have been introduced into drive control devices for electric vehicles. Since this thyristor chip repeatedly turns on and off a large current due to its nature, a pulsed noise electromagnetic field (hereinafter referred to as a noise electromagnetic field) is emitted from the electrical circuit of the thyristor chip and its peripheral equipment. in many cases. In particular, due to the structure of electric cars, the thyristor stopper device is often installed under the floor of the car, so it is very close to the tracks. Therefore,
The components of the noise electromagnetic field emitted by the thyristor stopper device that are present on the rail surface are directly induced in the loop coil and power receiver of the AF track circuit, and the harmonics of the noise electromagnetic field of the thyristor stopper device are directly induced in the AF track circuit. There is a danger that the signal wave of the receiver may be mixed with the signal wave of the receiver, causing the receiver to malfunction.

This will be explained in detail using figures. FIG. 4 is an explanatory diagram that extracts a part of FIG. 3 and shows details of the parts related to the power receivers P 1 and P 2 in the embodiment shown in FIG. 3.

Noise-induced voltages e o1 and e o2 are generated in the primary and secondary windings L 1 and L 2 individually wound on both sides of the iron core C, respectively, in the same direction with respect to the rail RL.

Since the noise induced voltages e o1 and e o2 cancel each other out, the received voltage E, which is a composite of E 1 and E 2 , contains almost no noise component, and the induced voltage E due to the signal current i.
Only the sum of E 1 and E 2 can be extracted. This also applies to the connection of power receiver P 1 and power receiver P 2 shown in the embodiment shown in FIG. exhibits.

In the figure, a shows a principle diagram of a power receiver used in the power receiving device according to the present invention, and b shows a principle diagram of a conventional power receiver.

により示される。 Here, the strength of the magnetic field generated by the current i flowing through the conductors A and B is determined according to the distance from the conductors A and B, and at a point r (m) from the center of the conductors A and B, the magnetic field strength at this point is Letting h(AT/m) be expressed by h≒i/2πr (1).

The electromotive force induced in this winding is proportional to equation (1) and determined depending on the number of turns and shape of the winding, and the magnetic permeability of the intervening material.

巻回された巻回数ｎの巻線ＬAには、次式により
示される起電力ｅAが誘起される。 Also, at b, a magnetic field is generated by the current i flowing through the conductor A, and at a distance r from the center of the conductor A.
When a power receiver having an iron core C A with a magnetic path length l 1 exists at a position, and a magnetic flux Φ A (Wb) passes to the iron core C A via a magnetic path length l 2 including space, the current i is Δt
If a change in Δi occurs during (sec), the magnetic flux Φ A also changes by ΔΦ A. Accordingly, the winding L A with the number of turns wound around the iron core C A has the following formula: An electromotive force e A is induced.

There is an annular iron core C B around the magnetic path length l
A closed magnetic path is formed, and if the current i changes by Δi as described above, the magnetic flux Φ B flowing through the iron core C B
also causes a change in ΔΦ B , and an electromotive force e B of the following equation is induced in the winding L B wound around the iron core C B with the number of turns n, similar to equation (2).
ｅB＝ｎΔΦＢ／Δｔ …(3)
たゞし、各磁束ΦA，ΦBは、(1)式およびこれの
通ずる磁路の透磁率に応じて定まり、これにした
がつて、ΔΦA，ΔΦBも定まる。 e B = nΔΦ B /Δt (3) Therefore, each magnetic flux Φ A and Φ B is determined according to equation (1) and the magnetic permeability of the magnetic path through which they pass, and according to this, ΔΦ A , ΔΦ B is also determined.
この透磁率をｂの場合μA、ａの場合をμBとす
れば、μAは全磁路長l2中に空間が介在し、空気
中の透磁率が小さく、μAも小となるのに対し、
μBは全磁路長ｌがすべて鉄心ＣB中であり、当然
にμBは大となり、μA≪μBの関係が成立する。 If this magnetic permeability is μ A for b and μ B for a, then μ A has a space in the total magnetic path length l 2 , the magnetic permeability in air is small, and μ A is also small. In contrast,
The total magnetic path length l of μ B is entirely in the iron core C B , so μ B is naturally large, and the relationship μ A ≪ μ B holds true.

大する。 Therefore, the power receivers P 1 and P 2 of the present invention are equivalent to those shown in Fig. 5a, and even if the signal current i and the number of turns n are the same, in the case of Fig. Compared to this, the magnetic flux Φ B flowing to the iron core C B becomes larger than Φ A , and accordingly, the electromotive force e B also increases significantly compared to e A.

Therefore, the influence of the noise electromagnetic field radiated by the thyristor stopper device can be extremely reduced, and a high receiving voltage can be obtained, thereby making it possible to prevent incorrect operation of the receiver.

Furthermore, since the current component of the signal current flowing through the rail can be easily extracted and the receiver can be prevented from malfunctioning, it has the effect of significantly increasing the reliability of the track circuit.

する受電装置。 In a power receiving device that detects a signal current flowing through the rails of a track, the central part of the magnetic path that constitutes the magnetic flux generated by the signal current flowing through one rail is substantially aligned with the rail, and extends across both sides of this rail and is perpendicular to the rail. An annular iron core provided along the direction, and a first winding wound on both sides of the iron core and connected so that the induced voltages generated in each are added.
The primary and secondary windings of the first and second windings are wound in the same manner as the first windings on an iron core similar to the iron core provided on the other rail, and are connected to each other.
and second primary and secondary windings connected so that the induced voltage by each winding and the own induced voltage are added, and the induced voltage proportional to the signal current of each rail is applied to the first and second primary windings. A power receiving device characterized in that power is received as a sum of induced voltages caused by each second winding.
