[Industrial application field]

The present invention is used for a vehicle-mounted station, and can be used with a 100V commercial power supply or
This invention relates to a transformer used as an input voltage to a 00 V commercial power source.

The radio station has a transmitting/receiving device installed in a car, etc., at a location of 1
4@There is a broadcast station.

In remote areas where commercial power is not available, such in-vehicle stations drive an engine generator to supply AC power (for example, 100 volts) to the transmitting/receiving device.
In places where commercial power can be used, 100V or 200V
A transformer receives commercial power through the interface panel 3, and converts it to a predetermined AC voltage (for example, 100V).
The data is converted into 100% and supplied to the transmitting/receiving device.

[Conventional technology]

A conventional transformer used in the above-mentioned vehicle-mounted station is constructed as shown in FIG. 13, and its output is, for example, 20 KVA.

In Fig. 13, a winding I6 and a secondary winding 7 are wound around the iron core 5, and the primary winding 6 has an input terminal 11 at the beginning of the winding, and another input terminal 13 at the end of the winding. Furthermore, an intermediate input terminal 12 is provided at the midpoint of the winding.

The secondary winding 7 is provided with an output terminal 16 at the beginning of the winding, another output terminal 18 at the end of the winding, and an intermediate output end f17 at the midpoint of the winding.

With this configuration, when receiving an input voltage of 200V, a commercial power line is connected to the input terminal f11 at the start end and the input terminal 13 at the end.

And the secondary side intermediate output terminal 17 and the terminal output terminal 7-1
A predetermined AC voltage (for example, 100 cm) is output to the 8 m.

Further, when receiving an input voltage of 100V, a commercial voltage line is connected to the intermediate input terminal 12 and the terminal input terminal 13.

And output terminal 16 at the start end of the secondary side and output terminal 1 at the end end
A predetermined AC voltage (for example, 100V) is output for 8 questions.

That is, if the number of turns of the primary winding 6 is 2N and the negative current is IO, the ampere turns on the primary winding side when the input voltage is 1 oov is oXN, and the ampere turns on the primary winding side when the input voltage is 200 mm. The turn is o X2N.

Therefore, the alternating magnetic flux generated in the iron core 5 when the input voltage is 100V is 1/2 of that when the input terminal is 200V.

Therefore, by using the output terminal 16 at the start end and the output terminal 18 at the end of the secondary winding, the number of turns used in the secondary winding is doubled compared to when the primary voltage is 200 V, and a predetermined number of turns can be applied to the secondary winding. AC voltage (for example, 100V) is output.

Moreover, as shown in FIG. 14, the end F15 of the commercial power supply is
It is connected to the input terminal 11 of the transformer by tightening the screw 19 and fixing it with the screw.

(Problems to be Solved by the Invention) As described above, the configuration in which electric wires are connected by screwing makes the connection work troublesome, and there is also a risk that the electrical connection may be incomplete.

In addition, vehicle-mounted stations are compact and have a timeless structure, which improves their mobility. As a result, the transformers to be installed are naturally required to be small and lightweight. Also, this transformer has negative voltages of 200V and 100V.
It is required that the secondary voltage be constant regardless of the

On the other hand, in order to satisfy these specifications of the transformer, in conventional transformers, when the negative side voltage is 100V, the ampere turns on the negative side are small, and the lack of alternating magnetic flux generated due to this is The number of turns in the secondary winding is doubled to compensate for the 200V case.

That is, the conventional transformer has a large number of turns in the secondary winding, which hinders miniaturization and lightness.

The present invention was created in view of these points, and enables easy and reliable electrical connection, is small and lightweight, and has two primary voltages, high and low, and a secondary voltage of a predetermined level. The purpose of this invention is to provide a transformer with constant voltage characteristics.

〔Example〕

FIG. 1 shows a transformer 20 according to one embodiment of the present invention.

The transformer 20 generally includes a transformer main body 21 and an interface 1 to a spacer panel 22 between the commercial power source and the input side of the transformer main body 21. As shown in FIGS. 2 to 3, these are installed in a so-called station 24 equipped with an automatic transmission/reception device 23, and in a power supply room 26 together with an engine power generator 8125.

The interface panel 22 is a part to which a commercial power source is connected, and is provided on the outer surface of one of the Tohoku stations.

This interface panel 22 and the transformer main body 21 are connected by internal wiring.

In FIG. 1, the iron core 30 has a pair of input ends "f-3".
A primary winding 33 with 1,32 and three output ends? 34
．． The secondary winding 37 having a diameter of 35.36 is a winding, respectively.

The primary winding 33 has two first windings having an equal number of turns. It consists of a second winding 38 and 39, and at the beginning of the winding of the first winding 138,

Note that the primary current in this case is Io. As described above, in both cases of input voltage of 100 V and 200 V, the ampere turns on the primary winding side are equal, so the alternating magnetic flux generated in the iron core is equal.

Therefore, the output terminals 34, 35 and 35 of the secondary winding 37
