In addition, the battery key is connected to the power supply line B via a rectifier (not shown). One of the switches 6 is connected to the control power line via a power breaker 28a, and the other is connected to ground via a normally "closed" contact 12a and a solenoid valve 9 for raising the pantograph. One of the switches 7 is connected to the power supply and the control 11EM line via the interrupter 28b, and the other is connected to the ground via the solenoid valve 11 for lowering the pantograph. In addition, line 2 is connected to pantograph lowering command line 5 via power breaker 28c.
5m is connected to the circuit between the switch 7 and the solenoid valve 10, and is also connected to the capture circuit (as shown) of the main circuit equipment. One side of the cab changeover switch 8 is connected to the power supply command line 5
and the other is normally open contact 12b and main 1#
When the detection circuit (not shown) is in the no-voltage detection state, it is connected to ground through the "closed" contact 14b% in series, the power supply establishment detection line, and the auxiliary relay. A power supply establishment indicator light 21 is provided on the power supply vehicle 2 side of the power supply establishment detection line n, and the end thereof is connected to ground. In addition, in the power supply command line, the power supply breaker 28d and the main tIl source detection circuit (not shown) are connected in series with the contact 14a which is "closed" when the no-voltage detection state and the power supply contactor 11 are connected in series. One end is connected and the other end of the circuit is tied to ground. Note that 13 is a rescue changeover switch that connects the control circuit when the power supply vehicle 2 is connected.

Next, the operation of the circuit configured as described above will be explained. When the electric car 2 is connected to the electric train 1 and the circuit is connected through the relief switch trench, the [source breaker 28a]
to 3C are normally open, and switches 6. to 3C on the train 1 side are normally open.
7 is "open", contact 12a.

14a and 14b are "closed", contact 11b is "open", cab selector switch 8 is switched on according to the direction of travel, and wL solenoid valve 10, contactor 11 and relay 12 are not energized, and , [#Switch 15 on the car 2 side is "open",
Switch 16 is "closed", contact 17a is "closed", contact 1
7 b, 18 a, 18 b, 20 a
, 20 b is "open", 4 is connected to 17.18. 2
0 is not excited, the contact 11a of the power supply line B is "open", and the source switch is closed to enable power supply.

When performing a power supply operation in this state, the switch 15 for turning on the power supply is pressed (the switch 15 then returns to "open" due to the spring return). As a result, the auxiliary relay 18 is excited by the voltage of the control 111E source line via the 'rIL# breaker 3C, switch 15, and contact 17a, contacts 18a and 18b are closed, and the auxiliary relay 18
The circuit is self-maintained through contact 18a, and
The voltage of the control power supply line 5 is applied to the pantograph lowering command line 5 via line 5b. As a result, power breaker 2
The pantograph lowering solenoid valve 10 is energized via 8c,
The air circuit of the cylinder that lowers the pantograph (not shown) is operated to lower the pantograph.

Also, above j! 81! By energizing the line 25a for protecting the illumination device, a command is given to turn off the main circuit protection device, thereby ensuring safety.

In addition, at the same time that the auxiliary relay 18 is self-held by the contact 18a, the time-limited relay 17 activates the timer function via the contact 18a by the voltage of the control 11L# line, and when a predetermined set time is reached, , the time-limited relay 17 is energized to open the contacts 17a and close the contacts 17b.

When the contact 17b is closed, the voltage from the control power line via the contact 17b is applied to the power supply command relay, and the relay is energized. This closes the contacts 20a and 20b. When the contact 20a closes, the voltage of the control power line is applied to the power supply command relay type via the switch 16 and the contact 20a, thereby self-holding the relay. Furthermore, when the contact 20b is "closed", the voltage of the control tL source line is applied to the power supply command line I via the contact 20b. The subsequent operation will be described later.

On the other hand, since the contact 17a becomes "open", the voltage from the control power supply line is no longer applied to the auxiliary relay 18 via the contact 18a, and the contacts 18a and 18b become "open". In particular, when the contact 18a becomes "open", the time-limited electric device 17 is no longer energized, and the contact 1
7a is "closed" and contact 17b is "open".

The contact 17a side is connected to the auxiliary joint [lH! 18
is not excited, but there is a risk that the contact 17b will open before the power supply command relay is self-maintained by the circuit of the switch 16 and the contact 20a. Therefore, even if the time-limited relay 17 is excited after a predetermined set time, the auxiliary relay 18 is excited by the voltage stored during energization by the holding circuit 19 so that the excitation of the auxiliary relay 18 does not stop due to this. extend the time,
Almost simultaneously with the excitation operation of the time-limited relay 17, the contact 18
This is to prevent the excitation of the time-limited relay 17 from becoming "open" and stop the excitation of the time-limited relay 17, thereby ensuring reliable operation of each circuit.

Next, when the power supply command line A is energized, the power supply contactor 11 is energized via the power circuit breakers 28d and 14a, so that the contact 11b is "closed" and the contact a of the power supply line is energized. is "closed" and power is supplied from the generator 5 to the power supply line. In addition, the auxiliary joint t'a1 is connected via the cab changeover switch 8 and contacts 11b and 14b.
2 is energized, which causes contact 12a to open.
Therefore, even if the switch 6 for raising the pantograph is operated, the solenoid valve 9 for raising the pantograph is not energized, thereby ensuring safety. At the same time, the power supply establishment detection line I is energized via the driver's cab changeover switch 8 and the contacts 11b and 14b, and the power supply establishment indicator light n is turned on.

With these operations, the power supply operation is completed.

Moreover, when stopping power supply, the release switch 16 is pressed to cut off the circuit. As a result, the excitation of the power supply command relay silver is stopped, and the contacts 20a and 20b become "open". When the contact point 20b is opened, the excitation of the power supply contactor 11 and the auxiliary vertical 112 is stopped, and the power supply establishment indicator light (■) is turned off. By stopping the excitation of the power supply contactor 11, contact 1
1a becomes "open" and power supply to the power supply line O is stopped, and contact 11b also becomes "open". By stopping the excitation of the auxiliary relay 12, the contact point a becomes "closed", and by operating the switch 6, the solenoid valve 9 for raising the pantograph can be energized. Further, by operating the switch 7, the solenoid valve 10 for lowering the pantograph can also be excited.

As described above, according to this embodiment, by operating the switch to turn on the power supply from the 11L power supply car 2 side, the pantograph addition of the train 1 can be lowered and power can be supplied from the power supply car 2 to the train 1, so that the pantograph You don't have to forget to lower it, and power can be supplied with a simple operation. In addition, the power supply can be easily stopped by operating the release switch from the electric tR single 2 side. These have the effect of preventing accidents and improving work efficiency.

In addition, after a predetermined period of time (at least the time required to complete the pantograph lowering operation) has elapsed after the command to lower the pantograph, the excitation of the solenoid valve for lowering the pantograph is stopped, thereby protecting the parts. can be done.

In addition, after the command to lower the pantograph is given, while power is being supplied, the pantograph is protected from being raised even if the pantograph is raised by mistake, which can further help prevent accidents. . In addition, when power is supplied, the pantograph is lowered before power is supplied, which further helps prevent accidents ◇ In addition, the contact 17a activated by the time-limited relay 17
, 17b, if there is an auxiliary relay 18 in the circuit 17a that serves as the activation source of the contact 18a that controls the operation of the time-limited relay 17, by providing the auxiliary relay 18 with a holding circuit 19, Even if the contact 17a is disconnected due to the operation of the time-limited relay 17, the excitation of the auxiliary relay 18 can be in-connected to protect the contact 18a from disconnection, and the function of the contact 17b (in this case, the self-maintenance of the relay field) This has the effect that circuit formation can be carried out reliably.
