Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric locomotive, and more particularly to an electric locomotive with improved main circuit wiring between a high-voltage equipment frame and a main motor.

[0002]

2. Description of the Related Art Conventionally, a wiring between a high-voltage device of an electric locomotive and a main electric motor penetrates a floor plate above the main electric motor and enters the inside of a vehicle body, and is connected to a terminal of a high-voltage device frame (Japanese Patent Laid-Open No. 2006-187242) 62
-199561).

[0003]

According to the above wiring structure, since wiring is made to various places inside the vehicle body, complicated wiring must be performed so as not to interfere with other wiring and piping, and the inside of the vehicle body When penetrating the partition wall that partitions each room, it is necessary to consider not to deteriorate the function of the partition wall. An object of the present invention is to provide an electric locomotive that can easily perform wiring of a main circuit wiring that connects a high-voltage device and a driving main motor.

[0004]

The above object of the present invention is achieved by extending the main circuit wiring to the outside of the vehicle body through a floor board near the high-voltage equipment.

[0005]

[Function] Since the floor board penetration portion of the main circuit wiring is located near the main circuit equipment, it is possible to avoid crossing with other wiring and piping, and since the partition wall is not penetrated, wiring is performed easily. be able to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1, 2 and 3. Generally, an electric locomotive has a driver's cab 14 at both ends of a vehicle body, and a machine room 15 between them, which is partitioned by a partition wall 8. The operator's cab 14 is provided with electrical components for controlling the operation of the locomotive. There is a cab 7. In the machine room 15, the main rectifier 2, the high-voltage device 3, and the electric brake resistor 4 are arranged on the left and right in the center of the main transformer 1 of the main circuit device along the flow of current. Near the wall 8, an empty frame 5, an auxiliary frame 6 and the like, which are electrical components of the control circuit device, are arranged. A trolley 12 for supporting the vehicle body supports a driving main motor 11 having a connecting box 10. Under the floor of the vehicle body, an underfloor connecting box 9 corresponding to each of the main electric motors 11 is attached, and the connecting box 10 and the underfloor connecting box 9 are attached.
In between is a lead wire 17 in consideration of the bias. A main circuit wire 16 is routed from each underfloor connecting box 9 through the floorboard 13 of the vehicle body to the high-voltage equipment 3 via this.
The main circuit wiring 16 and the lead wire 17 form a main circuit wiring. Regarding the wiring of the main circuit wire 16 between the underfloor connecting box 9 and the high-voltage equipment 3, the main circuit wire 16 coming out from the underfloor connecting box 9 is wired under the floor to the underfloor of the high-voltage equipment 3 to be connected. Where it goes through the floorboard 13 and is connected to the high-voltage equipment 3. According to the above structure, the control line 18 and the pipe 20 installed inside the vehicle body do not intersect with each other, and most of the wiring gutters inside the vehicle body only produce the electric wire gutters 19 for the control line, which is simple and lightweight. ， It becomes the electric wire gutter 19 which can reduce the cost drastically. Further, the main circuit line 16 is in the cab 1
Since it is not necessary to penetrate the partition wall 8 of 4, the wiring becomes simple.

[0007]

According to the present invention, since the main circuit line is penetrated under the floor in the high-voltage equipment section, there is less crossing with other wiring or piping, and there is no partition wall penetration, so wiring is simple. Becomes
