Description

[Technical Field]

[0001] The present invention relates to an electrical equipment box for a railway vehicle, a railway vehicle, and a method for inspecting a railway vehicle. [Background technology]

[0002] Generally, railway vehicles, which are one type of rail vehicle, have electrical equipment boxes installed under, on, or on the floor or roof that house electrical equipment and wiring for the railway vehicle, such as vehicle drive units that control the power supplied to the main motor, auxiliary power supply units that control the power supplied to on-board electrical equipment such as air conditioning, safety devices that house maintenance terminals, and battery units that store power during power outages or for running on non-electrified sections.

[0003] Patent Document 1 discloses, as an example of an electrical equipment box for a railway vehicle, a battery storage device for a railway vehicle that stores a plurality of batteries. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5374409 Summary of the Invention [Problem to be solved by the invention]

[0005] According to the battery storage device of Patent Document 1, the battery can be removed from the battery storage case, allowing battery inspection to be performed in a relatively bright environment. However, since it is difficult to remove a vehicle drive unit from a railway vehicle electrical equipment box, lighting within the railway vehicle electrical equipment box is required when inspecting the equipment housed in the railway vehicle electrical equipment box. However, the power supplied from the overhead line or the power from the battery equipment installed in the railway vehicle (referred to as railway vehicle drive power) is relatively high voltage, and the power supply from the overhead line is generally cut off during inspection of railway vehicle electrical equipment. Therefore, it is desirable to illuminate the interior of the railway vehicle electrical equipment box without using railway vehicle drive power. Therefore, workers often perform inspections while illuminating the dark interior of the box with a flashlight, headlight, or the like.

[0006] When inspecting such railroad vehicle electrical equipment boxes, workers must use a handheld flashlight to illuminate the inspection area inside the box, forcing them to work with only one hand, resulting in poor workability. One solution to this problem is to attach a magnetic light to the interior wall of the steel box, freeing up both hands, but this poses the problem of magnets not being compatible with aluminum or stainless steel boxes. Furthermore, while attaching a small light to the worker's helmet or similar allows for hands-free work, the light is projected only in the direction the worker's head is facing, leaving other areas dark, forcing the worker to be aware of their surroundings while working, resulting in poor workability.

[0007] An object of the present invention is to provide an electrical equipment box for a railway vehicle, a railway vehicle, and a method for inspecting a railway vehicle, which can illuminate the interior without relying on power for driving the railway vehicle and improve workability during inspection. [Means for solving the problem]

[0008] In order to solve the above problems, one representative railway vehicle electrical equipment box of the present invention is an electrical equipment box for railway vehicles that is attached to a railway vehicle, a housing for housing electrical components; an illumination unit attached to the housing and including a light source; a mounting portion for detachably mounting a portable power source for supplying power to the light source of the lighting unit; This is achieved by supplying electricity from the power source to the lighting unit by attaching the power source to the attachment portion.

[0009] In order to solve the above problems, one representative inspection method for an electrical equipment box for a railway vehicle according to the present invention includes: 1. A method for inspecting a railway vehicle equipped with an electrical equipment box for a railway vehicle, the electrical equipment box having a housing for accommodating electrical equipment, an illumination unit attached to the housing and including a light source, and an attachment part for detachably attaching a power source, the method comprising: This is achieved by attaching the portable power supply to the attachment portion, lighting the light source of the lighting unit using the power supplied from the power supply, and then inspecting the inside of the electrical equipment box for the railway vehicle. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide an electrical equipment box for a railway vehicle, a railway vehicle, and a method for inspecting a railway vehicle that can illuminate the interior without relying on power for driving the railway vehicle, thereby improving workability during inspection. Problems, configurations, and effects other than those described above will become apparent from the following description of the embodiments. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] Rail vehicles are vehicles that operate along laid tracks, and include railway vehicles, monorail vehicles, streetcars, new transit vehicles, linear motor cars, etc. In the embodiments of the present invention described below, a railway vehicle will be described as a representative example of a railway vehicle. The following embodiments can also be applied to railway vehicles other than railway vehicles.

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figure 1 is a perspective view showing an example of the overall structure of a railway vehicle equipped with a main converter according to an embodiment of the present invention. The main converter 1 controls a main motor 2 (Figure 6) that drives the railway vehicle, and in this embodiment, is installed in a suspended state under the floor of a car body 3.

[0014] FIG. 2 is a perspective view showing the exterior of a main converter according to an embodiment of the present invention. The main converter 1 is composed of a converter 4 that converts AC power to DC power by switching semiconductor elements, an inverter 5 that converts DC power to three-phase AC power, a circuit breaker for interrupting fault currents, and control equipment for sending control signals. The electrical components are connected to each other by electrical wiring such as electric wires and conductor bars, and are housed in a casing-shaped housing 10. The electrical equipment box containing the main converter 1 may be installed on the top surface of the car body 3, in which case the housing 10 is installed on the roof structure of the car body 3. The electrical equipment box may also be installed on the floor of the vehicle.

[0015] The housing 10 comprises a ceiling panel 11, a hanging portion 16 provided along the contour of the ceiling panel 11, a bottom panel 12, side panels 13, a front panel 14, and a cover holder 17 provided on the upper part of the front panel 14. The main converter 1 is fixedly installed in a suspended state on the car body 3 by joining the hanging portion 16 to the car body 3 with bolts (not shown). The front panel 14 of the housing 10 has an opening facing outward (outward in the width direction of the car body 3) perpendicular to the traveling direction of the car body 3, and the opening communicates between the inside and outside of the housing 10 and is covered by an inspection cover 60 that can be opened, closed, and removed. When the opening is closed and covered by the inspection cover 60, the inspection cover 60 is said to be in the closed position.

[0016] The inspection cover 60 is provided with a cover hook 61 located at its top, cover handles 62 located near both ends of the inspection cover 60 as handles, a cover clamp 63 located near the bottom end of the inspection cover 60 for securing the cover for opening and closing, and a keyhole 64 for locking the inspection cover 60. The inspection cover 60 is supported with the cover hook 61 hooked onto a cover holder 17 located above the opening in the front panel 14 of the housing 10, and is rotatable around the cover holder 17, allowing the inspection cover 60 to be removed from the closed position. The inspection cover 60 can also be configured to pivot around its upper edge rather than being completely separated from the housing 10. In such a case, it is preferable to provide a locking device (e.g., a stay or splint) that locks the inspection cover 60 in place when it pivots to a horizontal position (open position), for example.

[0017] Fig. 3 is a perspective view showing a main converter with an inspection cover open according to an embodiment of the present invention. Fig. 4 is a cross-sectional view showing the structure of an inspection cover for a main converter according to an embodiment of the present invention. Fig. 4 shows cross section AA in Fig. 3.

[0018] The inspection cover 60 consists of a rectangular front wall and an outer wall that surrounds the outer periphery of the front wall, and a cover packing 67 is provided around the entire inner periphery of the outer wall. When the inspection cover 60 is closed to the closed position, the cover packing 67 is pressed against the periphery of the opening in the front panel 14, thereby sealing the inside of the box and providing dustproof and waterproof functions.

[0019] On the inside of the inspection cover 60, there are provided a plurality of (for example, three) cover latches 65 that are linked to the cover clamp 63 that protrudes outward from the inspection cover 60 and rotate at an angle corresponding to the rotation of the cover clamp. Before attaching the inspection cover 60, the cover latch 65 is rotated so that it is parallel to the lower edge of the inspection cover 60, so that the inspection cover 60 can be attached in the closed position without interference between the cover latch 65 and the latch contact frame 18. After attaching the inspection cover 60, the cover latch 65 is rotated using the cover clamp 63 and brought into contact (engagement) with the back surface of the latch contact frame 18 provided on the front panel 14, thereby fixing the inspection cover 60 in the closed position and preventing the inspection cover 60 from falling off.

[0020] Additionally, a key latch 66 is provided on the inside of the inspection cover 60. The key latch 66 is linked only to a dedicated key (not shown) inserted into a keyhole 64 and rotates at an angle corresponding to the rotation of the key. Before attaching the inspection cover 60, similar to the cover latch 65, the key latch 66 can be rotated so that it is parallel to the lower edge of the inspection cover 60, thereby attaching the inspection cover 60 to the closed position without interference between the key latch 66 and the latch contact frame 18. After attaching the inspection cover 60, similar to the cover latch 65, the key latch 66 is rotated with a dedicated key to engage with the rear surface of the latch contact frame 18 provided on the front panel 14, thereby locking the cover. Specifically, the key latch 66, which constitutes a locking member, can be rotated between an engagement position (vertical position) in which the inspection cover 60 attached in the closed position is locked to the housing 10 and an open position (horizontal position) in which the inspection cover 60 can be opened by engaging the dedicated key. Unless the key latch 66 is disengaged from the latch frame 18, the inspection cover 60 cannot be opened, preventing unauthorized access to the inside of the housing 10. The key latch 66 and the latch frame 18 form a locking mechanism. The locking mechanism may be located on the housing 10 side.

[0021] To remove the inspection cover 60, an operator first inserts a dedicated key into the keyhole 64 and turns it to release the contact between the key latch 66 and the latch contact frame 18, which rotate in tandem, thereby unlocking the inspection cover 60. The operator then rotates the cover clamp 63 to release the contact between the cover latch 65 and the latch contact frame 18, which rotate in tandem, thereby unlocking the inspection cover 60 from the housing 10. The order in which the key latch 66 and the cover latch 65 rotate may be reversed. After unlocking and unlocking the inspection cover 60 in the closed position, the operator holds the cover handle 62 with both hands, rotates the inspection cover 60 around the cover holder 17, and removes the cover hook 61 from the cover holder 17 to remove the inspection cover 60 from the housing 10. The inspection cover 60 can be installed by reversing the removal procedure.

[0022] A lighting unit base 44 is provided on the ceiling panel 11 inside the housing 10, and the lighting unit 40 is attached to the lighting unit base 44 with bolts. The lighting unit 40 can uniformly illuminate the inside of the housing 10 during inspection. The lighting unit 40 is made up of a lighting unit frame 42, an LED lighting source 41, and a lighting unit connector 43 connected to the LED lighting source 41 via lead wires.

[0023] The side plate 13 near the opening inside the housing 10 is provided with a mounting section 20 for mounting a mobile battery 30, which is a power source for lighting the LED lighting source 41. The mounting section 20 is composed of a mounting section base 21 provided on the side plate 13 and a mounting section cover 22 that serves to position the mobile battery 30 when it is mounted and prevents it from shifting position after mounting. The mounting section cover 22 is connected to opposing upper and lower cover plates and side cover plates that connect the edges of the upper and lower cover plates, and is detachably joined to the mounting section base 21 with screws. The upper and lower cover plates of the mounting section cover 22 are horizontal, and the side cover plates are parallel to the side plate 13. When the mounting section base 21 and the mounting section cover 22 are joined, both ends are open, with a mobile battery connection terminal 51 attached to the inner end and the outer end remaining open, allowing the mobile battery 30 to be inserted through the opening of the housing 10.

[0024] The lighting unit 40 is electrically connected to a lighting unit connection terminal 52 at one end of a power cable 50, and the mounting portion 20 is electrically connected to a mobile battery connection terminal 51 at the other end of the power cable 50. The power cable 50 is fixed by a cable fastener 53 to a partition plate 15 that separates the rooms in the housing 10 that house the electrical devices. Note that the lighting unit 40 may be directly connected to the mounting portion 20 without using the electrical cable 50 as wiring.

[0025] 5 is a perspective view showing the appearance of a mobile battery according to an embodiment of the present invention. The mobile battery 30 includes a mobile battery output terminal 31 for outputting electricity stored in an internal secondary battery, a mobile battery input terminal 32 for charging the secondary battery, a mobile battery light 33 that functions as a light source for projecting light, a switch 34 for turning the mobile battery light 33 on and off, and a strap hole (attachment portion) 35 that can be used to attach a strap or the like to which the key for the inspection cover 60 is attached. The mobile battery 30 has a thin rectangular parallelepiped shape and is a portable (e.g., handheld) power source.

[0026] The mobile battery 30 of this embodiment has a lighting function, and by pressing the switch 34, the mobile battery light 33 is turned on using electricity stored in the secondary battery. By carrying one such mobile battery 30 with a lighting function, an operator can illuminate the inside of a railway vehicle electrical equipment box during inspection, even if the box does not have internal lighting, and the attachment unit 20 can be easily seen even in dark environments.

[0027] Furthermore, by attaching a strap such as a key for the inspection cover 60 to the strap hole 35, the key and the mobile battery 30 are used as a single unit, which prevents the mobile battery 30 from being left inside the device when locking the inspection cover 60. Note that a strap with an electronic tag or the like attached to prevent loss may be attached to the strap hole 35.

[0028] The mobile battery 30 used in this embodiment has a volume of 6000 cm 3 The following sizes are suitable, allowing inspection work to be performed without being hindered by the mobile battery 30 attached to the attachment part 20. Note that a dry battery box containing multiple dry batteries may be used instead of the mobile battery 30.

[0029] Fig. 6 is a circuit diagram according to an embodiment of the present invention before a mobile battery is attached. Fig. 7 is a circuit diagram according to an embodiment of the present invention after a mobile battery is attached. Figs. 6 and 7 partially show an example of a circuit related to an LED lighting circuit and a railway vehicle electrical system.

[0030] The circuits related to the railway vehicle electrical system are composed of a pantograph 71, a transformer 72, a main conversion device 1 including a converter 4 and an inverter 5, a main motor 2, an auxiliary power supply device 73, a battery charging device 74 for driving the vehicle, and a battery device 75 for driving the vehicle. The main conversion device 1, the auxiliary power supply device 73, the battery charging device 74, and the battery device 75 are called electrical equipment, and are arranged inside a housing 10 and inspected as necessary.

[0031] AC power obtained from AC overhead lines 70 is stepped down via transformer 72. Converter 4 converts the stepped-down AC power into DC power and supplies it to inverter 5, which is located downstream of converter 4. The supplied DC power is then converted by inverter 5 into three-phase AC of any frequency and voltage and supplied to traction motor 2. Using the three-phase AC of any frequency and voltage, traction motor 2 generates driving force that rotates wheels 7 of bogie 6, thereby accelerating and decelerating the railway vehicle.

[0032] The auxiliary power supply 73 converts the AC power stepped down by the transformer 72 into three-phase AC of a specific frequency and voltage, one side of which is supplied to a battery charging device 74 located downstream of the auxiliary power supply 73, and the other side of which is supplied as power for vehicle lighting, indicator lights, air conditioning, and other devices. The supplied three-phase AC is converted into DC power by the battery charging device 74, a portion of which is supplied to a battery device 75, and the remainder is supplied as power for the main converter 1, etc. The supplied power is stored in the battery device 75 and is supplied as power for the main converter 1, etc. when the auxiliary power supply 73 is not operating.

[0033] The LED lighting circuit of this embodiment is composed of a lighting unit 40, an attachment section 20, and a mobile battery 30. During inspection work, with the inspection cover 60 removed from the housing 10, the worker holds the mobile battery 30 and moves it horizontally toward the attachment section 20 as shown in FIG. 3 . At this time, the attachment section cover 22 guides the mobile battery 30, allowing the mobile battery 30 to be attached to the attachment section 20 while maintaining its posture. Furthermore, when the mobile battery 30 is attached to the attachment section 20, the attachment section cover 22 holds the mobile battery 30 so that electrical continuity is maintained between the battery output terminal 31 and the mobile battery connection terminal (also referred to as the input terminal) 51.

[0034] Furthermore, when attached to the attachment section 20, the end of the mobile battery 30 protrudes from the attachment section cover 22, so after completing the inspection, the worker can easily remove the mobile battery 30 from the attachment section 20 by grasping the protruding end of the mobile battery 30.

[0035] When the mobile battery 30 is attached to the attachment section 20, the terminals of the mobile battery output terminal 31 and the mobile battery connection terminal 51 engage with each other and become electrically connected, and the power stored in the mobile battery 30 is supplied to the LED lighting light source 41, causing the LED lighting light source 41 to light up.

[0036] The LED lighting circuit is a circuit independent of the railway vehicle electrical system circuit. This means that the LED lighting source 41 can be turned on when the power to the main converter 1 is turned off, in other words, without relying on power from the overhead line 70 or the battery device 75 installed in the vehicle. Because the power of the mobile battery 30 is small, it can illuminate the inside of the box at an extremely low voltage. Therefore, even if a worker were to touch the LED lighting circuit, there is no risk of electric shock, allowing for comfortable and safe inspection work on railway vehicles.

[0037] FIG. 8 is a flow chart showing the work procedure when inspecting the main converter according to the embodiment of the present invention. For safety reasons, an operator starts the inspection work with the power supply to the main converter 1 cut off so that the inspection can be carried out in a power-off state (step S1).

[0038] The worker unlocks and releases the inspection cover 60 as described above, and releases the inspection cover 60 from the closed position (step S2). The worker then attaches the mobile battery 30 that they are carrying to the attachment part 20 of the main converter 1 (step S3). The power stored in the mobile battery 30 is supplied to the LED lighting source 41 of the main converter 1, and the LED lighting source 41 lights up (step S4). Even if the worker lets go of the mobile battery 30, the mobile battery 30 will not fall off from the attachment part 20.

[0039] With the inside of the main converter 1 uniformly brightly lit, the worker inspects the main converter 1, for example, using both hands (step S5). After the inspection is completed, step S6 distinguishes between the two cases. Specifically, if the worker removes the mobile battery 30 from the mounting unit 20, the process proceeds to step S7; if the worker forgets to remove the mobile battery 30 and leaves it attached to the mounting unit 20, the process proceeds to step S9.

[0040] When the mobile battery 30 is removed from the mounting portion 20, power supply to the LED illumination light source 41 is cut off, and the LED illumination light source 41 is turned off (step S7). Then, the worker closes the inspection cover 60 (step S8).

[0041] On the other hand, if the worker forgets to remove the mobile battery 30 and leaves it attached to the attachment section 20, the inspection cover 60 will not close properly as described below, and the worker will realize that he or she has forgotten to remove the mobile battery 30. Then, the process returns to step S6, and the worker removes the mobile battery 30. After that, the worker finishes the inspection and resumes the power supply to the main converter 1 (step S10).

[0042] Fig. 9 is a cross-sectional view showing a structure in which the inspection cover of the main converter cannot be closed when a mobile battery is attached, according to an embodiment of the present invention. Fig. 9 shows cross section AA in Fig. 3. Using Fig. 9, the structure in which the inspection cover 60 cannot be closed in step S9 in the flowchart of Fig. 6 will be described.

[0043] According to this embodiment, a stopper 68 is provided on the inside of the inspection cover 60 and is attached facing the mounting portion 20, protruding from the inner surface of the inspection cover 60. The stopper 68 is preferably made by bending a long, thin plate into a roughly U-shape, with both ends joined to the inner surface of the inspection cover 60 by welding or bolts. When the mobile battery 30 is not attached to the mounting portion 20, as shown in FIG. 3, the stopper 68 approaches close to the mounting portion cover 22, allowing the inspection cover 60 to be completely closed in the closed position and to be fixed and locked.

[0044] On the other hand, when attempting to close the inspection cover 60 with the mobile battery 30 attached to the attachment portion 20, the stopper 68 provided on the inside of the inspection cover 60 abuts against the end face of the mobile battery 30 and interferes with the mobile battery 30. As a result, the inspection cover 60 does not close completely (does not reach the closed position), and the worker realizes that they have forgotten to remove the mobile battery 30. This prevents the worker from leaving the mobile battery 30 attached to the attachment portion 20 inside the box when inspecting the main converter 1. In other words, when the mobile battery 30 is removed from the attachment portion 20 and the inspection cover 60 is attached to the closed position, the stopper 68 does not interfere with the attachment portion 20, allowing the inspection cover 60 to reach the closed position. On the other hand, if the mobile battery 30 remains attached to the attachment portion 20, the stopper 68 interferes with the end face of the mobile battery 30, making it impossible to attach the inspection cover 60 to the closed position.

[0045] It should be noted that the present invention is not limited to the above-described embodiment, and includes various modifications.
