[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cubicle type of power source lighting lighting system in which an internal power source is turned on during operation and an externally mounted power source is turned on by an external power source during construction or maintenance inspection when power transmission is stopped. High voltage power receiving equipment.

[0002]

2. Description of the Related Art Generally, in a cubicle type high voltage power receiving equipment, a lighting device for internal lighting is fixed to a case body above a device mounting panel. This lighting system uses the internal power supply during operation to turn it on by turning on the switch, and mainly illuminates the surface of the device panel to facilitate reading of the measured value of the indicating instrument that displays power information during operation.

[0003]

However, since the conventional cubicle-type high-voltage power receiving equipment lighting system can only be used when the system is in operation and has an internal power source, work in the work space during construction or maintenance inspection is not possible. In that case, there is a drawback that a portable lighting device that illuminates the work place must be prepared.

Therefore, the present invention solves the above-mentioned problems of the prior art by illuminating the surface of the equipment panel during operation and illuminating the work space during construction and maintenance / inspection to facilitate construction and maintenance / inspection work. It is an object of the present invention to provide a cubicle-type high-voltage power receiving equipment of a power supply lighting lighting system for improving efficiency and efficiency.

[0005]

In order to achieve this object, the cubicle type high voltage power receiving equipment of the present invention has an external power source connection terminal provided on an internal equipment mounting panel and an internal power source or an external power source for switching between two power sources. A switch, a lighting device, a lighting device mounting arm, an arm support shaft, an arm rotation stopper, an arm stop holding magnet catcher, and an arm rotation hook rod insertion hole are provided.

[0006]

With this configuration, in the cubicle type high voltage power receiving equipment of the present invention, the power source is taken from the inside during operation, the power source switching switch is set to "ON" during operation, and the lighting equipment is mounted by the function of the rotating arm. Move to the position to illuminate the panel surface, and during construction maintenance inspection where power transmission is stopped, power is taken from the external power source through the external power supply connection terminal. The tool is moved to the position where the upper part of the work space is illuminated by the action of the rotating arm. That is, the lighting device can be turned on during operation and maintenance / inspection, and it is possible to improve the easiness and efficiency of the indicator reading and construction / inspection work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1, 2 and 7, 1 is a cubicle type high voltage power receiving equipment (hereinafter referred to as cubicle) main body,
Inside thereof, 2 is a device mounting panel, 3 is a lighting fixture for illuminating the interior, 4 is a power conversion transformer 5, 5 is a switch for protecting the primary side of the transformer 4, and 6 is a working space for construction maintenance inspection.

FIG. 3, FIG. 4, FIG. 5, and FIG. 6 are perspective views of the device mounting panel 2 in this embodiment.
I will also explain.

Reference numeral 7 is an indicator for displaying the secondary side power information of the power conversion transformer 4, 8 is a breaker for protecting the secondary side of the power conversion transformer 4, 9 is an external power supply connection terminal for the lighting fixture 3, and 10 is lighting. An internal power source / external power source lighting switch for the fixture 3, 11 is an arm for mounting the luminaire 3, 12 is a shaft for supporting the arm, 13 is a stopper for stopping the rotation of the arm 11 rotating via the shaft 12, Reference numeral 14 is a magnetic catcher for holding the arm 12 in a stopped state, and reference numeral 15 is a hole for inserting a hook rod for rotating the arm.

The operation of the cubicle configured as described above will be described with reference to the flowchart of FIG.

In step (1), the power supply switching lighting switch 10 is turned off. Next, if it is in operation, move to step (2) A, and the lighting fixture 3 attached to the arm 12
Is moved to the upper part of the device mounting panel 2 by the action of the rotary arm 12 using the hook bar 16 to bring it to the position shown in FIGS. In step (3) A, the power switch for lighting D
0 is turned on during operation. In step (4) A, the luminaire 3 is turned on to illuminate the indicating instrument 7.

If it is under construction maintenance inspection, the procedure goes to step (2) B, and the lighting fixture 3 attached to the arm 12
Is moved to the upper part of the work space 6 by the action of the rotating arm 12 by using the hook bar 16 and brought to the position shown in FIGS. In step (3) B, the external power supply is connected to the external power supply connection terminal 9. In step (4) B, the power source switching lighting switch 10 is set to "ON" during construction maintenance inspection. Step (5)
In B, the luminaire 3 is turned on to illuminate the work space 6.

As described above, according to this embodiment, the luminaire 3 can be turned on during operation, construction and maintenance inspection,
It is possible to improve the easiness and efficiency of indicator meter reading and construction maintenance inspection work.

In this embodiment, the lighting fixture mounting arm 1
Although 2 is rotated in the horizontal direction, it may be rotated in the vertical direction. In this case, the structure is simplified and economical.

[0016]

As described above, according to the present invention, the equipment mounting panel is provided with the power source switching lighting switch and the external power source connecting terminal during operation and during construction maintenance inspection, while being movable via the arm. Since the lighting equipment is installed in the equipment, it is possible to prove the surface of the equipment mounting panel during operation and the work space during construction maintenance inspection. Therefore, it is possible to surely improve the easiness and efficiency of the indicating instrument meter reading and the construction maintenance inspection work.
