Abstract

PURPOSE:To simplify a switching circuit and to reduce the number of wirings by connecting a power supply means to a load at each vehicle at the time of normal state, and connecting a power supply means of an adjacent vehicle to the load when the power supply means becomes defective. CONSTITUTION:The contacts 10b-30b of a voltage detector are closed at the time of normal state. When switches 12-32 are closed in this state, voltage contactors 13-33 are energized. Thus, main contacts 13a-33a are closed to supply power from transformers 10-30 to loads 11-31. On the other hand, if the power source of a train C becomes defective, the contact 30a of the detector is opened. Thus, the contactor 33 is deenergized, and the contact 33a is opened. When a switch 35 is closed in this state, a power supply contactor 34 is energized to close a main contact 34a. Thus, the load 31 of the train C is supplied with power from a main transformer 20 of a train B.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an in-train power supply circuit, and particularly to an in-train power supply device suitable for a power supply system in which power sources are distributed among a plurality of vehicles.

[Conventional technology]

In conventional equipment, the output line for each power source is wired inside the train.
When the vehicle's power supply malfunctions, it is either directly switched manually using a rectangular switch or remotely controlled using an electromagnetic contactor.

In addition, related to this type of device.

For example, JP-A-59-11701 and the like can be mentioned.

[Problem to be solved by the invention]

The conventional technology described above does not take into account the simplification of the switching circuit and the reduction in the number of wires, resulting in an increase in problems.

There was a problem with the complexity of handling.

An object of the present invention is to solve the above-mentioned problems and provide an inexpensive and easy-to-handle in-train power supply device.

[Means to solve the problem]

The above purpose is to provide an in-train power supply system in which a power supply means and a load are provided for each train. auxiliary connection means for connecting the and the other load;
A main connection command means that issues a connection command to the main connection means and an auxiliary connection command means that issues a connection command to the auxiliary connection means are provided, and the auxiliary connection means of at least one of each vehicle can operate the auxiliary connection means of an adjacent vehicle. This is achieved by connecting to.

[For production]

During normal operation, the main connection means is operated by the main connection command means provided for each vehicle to connect the power supply means for each vehicle and the load. If any power supply means of each vehicle fails, the auxiliary connection command means of that vehicle operates the auxiliary connection means to connect the load to the power supply means of the adjacent vehicle.

In addition, if at least one vehicle in each vehicle (for example, a vehicle at the end) breaks down, the auxiliary connection means of that vehicle activates the auxiliary connection means of the vehicle immediately before, and the vehicle immediately before the vehicle breaks down. Contrary to the case, the power supply means of the preceding vehicle is connected to the load of the vehicle at the end. This allows for inexpensive and easy handling.

・　3 〔Example〕 An embodiment of the present invention will be described below with reference to FIG.

In this case, FIG. 1 shows a four-car train, with car A being the leading car. Car A is provided with a transformer 10 and a load 11, and the transformer 10 and load 11 are connected through a main contact 13a. In addition, the control power line 17 of the control power source 6 is connected to a voltage contactor 13 via a switch L and a voltage detector 10a, a switch L, a contact 13b and a contact 10b.
A power supply contactor 14 is connected to the power supply contactor 14 via the power supply contactor 14 . moreover,
A line branched from between switch 15 and contact 13b is connected to the diode of car B via contact 14b. The voltage detector 10a detects the voltage of the transformer 10, and if the transformer 10 is normal, it detects the voltage and becomes "human", and at this time, the contact 10b is in the "off" state. ing. The voltage contactor 13 is in an excited state, and the main contact 13 a
Turn on, and turn contact 13b off. Power supply contactor 1
4 is in an excited state, and the contact 14b is connected to one person.

Car B is equipped with a transformer like car A, and has a main flashing point 23a.

The circuit of the load 21, the switches connected to the control power line 17, the voltage detector 20a, the circuit of the voltage contactor B, and the switch 5. A contact 23b, a contact 20b, and a power supply contactor circuit are provided. Further, in this case, a circuit branched from between the load 21 and the main contact 23a and via the main contact 24a is connected between the load 11 of the A car and the main contact 13a. Further, a circuit branched from between the contact 20b and the power supply contactor path via a diode is connected to the contact 14b of car A. In this case, the power supply contactor is in an excited state and turns on the main contact 24a.

Additionally, the diode prevents current from flowing backwards from the B car side to the A car side, increasing safety.

Car C and car B are the same except that car B does not have a circuit including a diode, so a description thereof will be omitted.

In this case, the power supply means is the transformer 10, 20°, the main connection means consists of the voltage contactor 13, 23, 33 and the main contacts 13a, 23a, 33g, and the auxiliary connection means is the power supply contactor. 14, 24, 34, contacts 14b and main contacts 24a, 34a, the main connection command means is the switch 12, 22, 32, and the auxiliary connection command means is the switch 15, 25. It is 35.

In the device configured as described above, power is supplied to the load in the following manner under normal conditions.

The operation is the same for all cars, so we will explain it using car A as an example.

Since voltage is applied to the transformer 10, the voltage detector 10
a is in the "on" state, and the contact 10b is in the "off" state. In this state, when the switch is turned on, the voltage contactor 13 is energized from the control power line 17, and the voltage contactor 13 is excited. As a result, the main contact 13 a
is turned on, and power is applied from the transformer 10 to the load 11. Furthermore, the contact 13b is turned off by the energization of the voltage contactor 13. As a result, from the transformer 10 to the load 11
While energizing is in progress, the power supply contactor 14 is not energized even if the switch 15 is turned on, providing double safety.
Each vehicle is powered by its own transformer.

Next, in this case, B excluding the leading vehicle, 0. A description will be given of what to do when one of the vehicles B malfunctions, that is, the power cannot be supplied to the load. Vehicle B
,0. Car D operates in the same way, so we will discuss the case where car C breaks down, for example. When the voltage is no longer applied between the transformers, the voltage detector 30a turns off. As a result, the power supply from the control power line 17 to the voltage contactor O is cut off, the voltage contactor O is no longer energized, and the main contact 33
a becomes "cut". In addition, when the voltage detector 30a becomes "off", the contact 30b becomes "human", and when the voltage contactor is no longer energized, the contact &lb becomes "on", and the power supply contactor is energized. Ready. By turning on the Suivuchi residence in this state, the control power line 17
Electricity is applied from to the power supply contactor A, and the power supply contactor is energized. As a result, the main contact 34a of 1C is turned on and connected to the transformer voltage +a20 of the B car, and the load 31 of the C car receives power from the transformer swing of the B car. Similarly, when car B breaks down, power is supplied from car A, and when car D breaks down, power is supplied from car C.

In this way, if a vehicle after the lead vehicle breaks down, power can be supplied from the next vehicle. In addition, the transformer of each vehicle has main contact 2 that operates by swinging the power supply contact and
4a and 34a, each vehicle is independently separated during normal operation.

Next, a case where car A, the leading car, breaks down will be explained.

In Car A, the process is the same until the switch 15 is turned on and the power supply contactor 14 is energized, so the explanation will be omitted. In this case, when the feed contactor 14 is energized, the contact 14
b becomes “on” and the control power line 1 is connected through the diode diode.
7, power is applied to the swinging power supply contact of car B, and the power supply contact separation is energized. This causes the main contact 24a of car B to turn on.
, A is connected from between the transformers of car B through the main contact 24a
The load 11 of the vehicle is energized.

As described above, according to this embodiment, any vehicle can receive power from the power source of an adjacent vehicle by simply operating the failed vehicle when the own vehicle's power supply fails due to the simple circuit. The processing work can be done quickly, and the power supply circuit can be made at low cost.

Next, another embodiment of the present invention will be described with reference to FIG. In this case, the AI is the same as that of car A in Figure @1, and the explanation will be omitted. Further, car E connected to car A has a transformer shaft and a main contact 43a, similar to car B in FIG.

The circuit of the load 41, the circuit of the main contact 44a, and the control voltage
Switch 42 connected to 17. Voltage detector 40a,
A circuit for a voltage contactor, a circuit for a switch, a contact 43b, a contact 40b, a power supply contact device, and a circuit for a diode are provided, and a detailed explanation thereof will be omitted. The difference in configuration from car B in Figure 1 is as follows. Switch 6 and contact 43b
There is a circuit connected between the switch 47 and the contact 44b to the diode of the F car.
This circuit has the same role as the circuit provided with the contact 14b of car A. However, if there is a vehicle connected in front of the 5E car, the switch 47 is turned off. Note that the contact 44b is turned on by excitation of the power supply contact device, but
Since the switch 47 is turned off, the power supply connection for car F'
No electricity is applied to the M shaver. Therefore, since the operation and effects are the same as those of the previous embodiment, the explanation will be omitted.

In this embodiment, all the other vehicles are the same except for car A, which is the leading car, and can be standardized. Also,
If you remove the lead car A and turn on the switch 47 of car E, car E will become the lead car and the same switch 47 as car F will be turned on.
If you connect vehicles with 1 cut, all the vehicles will be the same, allowing for further standardization.

In addition, in these examples, the vehicle that received power by activating the power supply contactor of the adjacent vehicle was the lead vehicle.
This can be anywhere.

〔Effect of the invention〕

Advantageous Effects of Invention According to the present invention, in a power supply system in which power sources are distributed and allocated to a plurality of vehicles, the power supply system can be inexpensive and easily handled.
