Problems solved by technology

[0006] In Patent Document 1, when one vehicle is added or subtracted from an arbitrary formation, there is a problem that the reorganization becomes complicated
For example, if there are 17 cars other than cars 3 to 5 in a 20-car formation, and later to change to an 18-car formation, it is necessary to return to 20 cars including the 3 cars that were originally excluded. After grouping, car 2 and car 12 or car 10 and car 11 are excluded, so it is not easy to regroup

Embodiment 1

[0027] figure 1 It is a figure which shows the drive system of this Example. In this specification, a vehicle equipped with a power conversion unit and an AC motor is referred to as an M vehicle, and a vehicle not equipped with these structures is referred to as a T vehicle. In the case of adding a T car to the formation train, it is only necessary to connect the communication lines and the like of the cars before and after the T car to be added. That is, the present embodiment shows a train formation capable of adding vehicles regardless of M cars and T cars. In this specification, the case where a vehicle is further added to the trains constituting the train set is referred to as adding a train, and the case where a vehicle is removed from the trains constituting the train set is referred to as a reduction.

[0028] The marshalling train is equipped with: a power collection unit 1, which obtains single-phase AC power from an overhead line (not shown) connected to a substat...

Embodiment 2

[0037] Figure 5 It is the second embodiment of the driving system of the train consisting of M cars that can be added in the same way as in the first embodiment. The structures of the power collection unit 1, the transformer unit 2, the power conversion unit 41 for the power supply, the smoothing capacitor 51, the power conversion unit 61 for the motor, and the AC motor 71 are also the same as those in Embodiment 1, and the Figure 5 The formation train of the structure drives AC motor 71. The power line connectors 34, 35, and 36 need only be installed between the respective vehicles and the vehicles.

[0038] As long as the structure of the M car added in embodiment 2 is the same as figure 2 Just the same. In the formation train of Embodiment 2, by setting the contactor 35 into an open state, it is possible to apply a voltage to the section between the contactor 35 and the contactor 32 on the power supply cable 8 for the additional M car. run. In addition, since a high...

Embodiment 3

[0043] Figure 6 It is the third example using the structure of the first example.

[0044] In the first embodiment, the M car 101 for adding vehicles is added not only beside the vehicle 101 including the transformer unit 2 , but also the M car 101 for adding vehicles is added between the vehicle 201 and the vehicle 301 . On the other hand, in this embodiment, the additional M car 103 is connected between the vehicle 103 equipped with the transformer unit 2 and the vehicle 203 connected to the vehicle 103, and an M car can be added to the train formation. The driving system of this embodiment only needs to be connected with figure 1 or image 3 It only needs to be the same, and it can be realized by adjusting the length of the power supply cable 8 . In the present embodiment, the length of the power supply cable 8 included in the train consisting of the vehicles 103 to 603 can be set to be shorter than that of the first embodiment by approximately the amount corresponding ...

Abstract

An object of the invention is to increase and decrease cars of a train set one by one while dispersing axle load of a train constituting a train set. In order to achieve the object, a train set constituted by coupling a plurality of cars of the invention includes a current collector that obtains power from outside of a train, a transformation means that transforms the power supplied from the current collector, a power conversion means that converts the power output from the transformation means into AC power having a variable voltage and variable frequency, an AC motor driven by the power conversion means, a first power supply cable having one end connected to a secondary side of the transformation means and the other end connected to the power conversion means and supplying the power output from the transformation means to the power conversion means, and a second power supply cable having one end that can be connected to the secondary side of the transformation means and the other end electrically opened.

Description

technical field [0001] The present invention relates to forming trains. Background technique [0002] Generally, the number of passengers using the railway varies depending on the region and section in which the train operates, or the season and time zone. In addition, in transportation using railroads, the amount of transportation is not always the same every time. Therefore, flexibly adjusting the number of vehicles constituting a train consist in accordance with the number of passengers, transportation volume, etc. leads to improvement of operating efficiency and reduction of operating cost. As a technique for changing the composition length, there is JP-A-4-126658 (Patent Document 1). In Patent Document 1, it is disclosed that, in a formation having a plurality of power units in which one power-receiving power vehicle is arranged on both sides of a power-supplying vehicle, and a unit of three is arranged, by arranging the power units between each other, Trailer, there...
