Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency battery connection system suitable for restarting an auxiliary power supply such as a motor generator or a stationary inverter of an emergency stopped train, and an emergency battery thereof.

[0002]

2. Description of the Related Art A conventional electric train is equipped with a battery that is charged during normal traveling. When an emergency such as a stop of power supply from an overhead line occurs, an emergency light in the car and a minimum required electric power are supplied. Power is supplied to the service equipment from the battery, and the minimum necessary functions of the service equipment are maintained even while the power supply from the overhead line is stopped. Then, when the emergency is restored, the auxiliary power supply device such as the motor generator or the stationary inverter is restarted by using the electric power supplied from the battery so that the self-propelled running can be resumed.

[0003]

However, in the case of a train equipped with the above-mentioned conventional battery, the battery is over-discharged due to the occurrence of an electrical trouble in the overhead line or rail, and the function should be maintained in an emergency. In some cases, it may not be possible to supply the minimum necessary service equipment.

[0004] In this case, when the emergency is restored, the auxiliary power supply cannot be restarted and the self-traveling cannot be resumed, so that all the functions of the train are stopped to wait for rescue by another train. Therefore, there has been a problem that the operation of the train is stopped for a long time.

[0005] As a solution to this problem, there is a plan to replace the over-discharged battery itself with a fully charged battery, a plan to supply power to a DC 100 volt circuit connected to the battery by using some external power source, and the like. Although it is conceivable, the former scheme has a problem in transporting and storing a battery of several hundred kg, and the latter scheme has the following problems.

A specific external power supply for a vehicle does not exist. A ground power supply that supplies power to a DC 100 volt circuit is not always available along the railway. A very large capacity power supply is required to supply power to the DC 100 volt circuit of the entire formation.

The present invention solves the above-mentioned problem by connecting a portable emergency battery having a minimum power capacity required to start the auxiliary power supply unit instead of a battery to a train. An emergency battery connection comprising a connection mechanism and a power supply switching mechanism for switching power supply from a battery to an emergency battery to supply power to a starting circuit and the like of the auxiliary power supply device on the train by connecting the emergency battery to the connection mechanism. It is to provide a system and an emergency battery that is portable and easy to transport and store.
