DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure of a low-voltage main line connecting a transformer and low-voltage equipment provided in a cubicle-type high-voltage power receiving facility.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 2, a cubicle type high-voltage power receiving equipment 21 is provided with a transformer 23 for converting a high voltage to a low voltage inside a box 22, and an inspection passage through which an operator can walk. On the opposite side of the transformer 24 from the transformer 23, a plate-like low-voltage panel 25 is installed substantially vertically, and a low-voltage device 26 is attached to the low-voltage panel 25. And transformer 2
The low-voltage trunks 28, 28, 28 of the cables connected to the secondary terminals 27, 27, 27 of No. 3 were connected to the low-voltage equipment 26 of the low-voltage panel 25 through the upper space of the inspection aisle 24. Protective plates 29, 29 are provided on the left and right sides of the inspection aisle 24 so as to prevent an operator from contacting various devices and causing an accident.
Was installed.

[0003]

However, the height L from the inspection passage 24 to the low-voltage main line 28 is about 1600 m.
m, the worker walks on the inspection aisle 24, and the low-voltage trunk 28 obstructs the work,
Further, there is a possibility that the worker may hit the head and get injured.

When a conductive bar is used for a low-voltage main line, the conductive bar is exposed, so that an operator may come into contact with the conductive bar and cause an electric shock or a short circuit. It was necessary to install a protective plate for insulation.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the conventional cubicle-type high-voltage power receiving equipment, an object of the present invention is to provide an inspection work that can be safely performed without any trouble on an inspection aisle and to improve workability. Provide a cubicle-type high-voltage power receiving equipment that has at least a transformer inside the box, and a low-voltage panel installed on the opposite side of the transformer with an inspection walkway where workers can walk. In a cubicle-type high-voltage power receiving facility that has a low-voltage device attached to the low-voltage panel and a low-voltage trunk line that connects the secondary terminal of the transformer and the low-voltage device, the low-voltage main line was routed through the lower part of the inspection aisle. It is.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION
A transformer that converts high voltage to low voltage is provided inside the box, and a plate-like low-voltage panel is installed almost vertically on the opposite side of the transformer across the inspection walkway where workers can walk. The panel is equipped with low-pressure equipment. Then, in order to wire from the transformer to the low-voltage equipment, the low-voltage main line of the cable connected to the secondary terminal of the transformer is connected to the low-voltage equipment through the lower part of the inspection aisle.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the cubicle type high-voltage power receiving equipment according to the present invention will be described with reference to the accompanying drawings of FIG.

[0008] The cubicle-type high-voltage power receiving equipment 1 comprises a box 2
A transformer 3 for converting a high voltage to a low voltage is provided in the interior of the vehicle.
On the opposite side, a plate-like low-voltage panel 5 is installed substantially vertically, and a low-voltage device 6 is attached to the low-voltage panel 5.

To connect the transformer 3 to the low-voltage equipment 6, the low-voltage trunk lines 8, 8, 8 of a plurality of cables connected to the secondary terminals 7, 7, 7 of the transformer 3 are connected to the transformer 3. To the lower part of the box 2, change the direction near the bottom plate 9 of the box 2, and wire it toward the bottom panel 5, and upward along the bottom panel 5 near the bottom panel 5 through the lower part of the inspection aisle 4. And connected to the low-voltage equipment 6. Protective plates 10 and 10 are installed on the left and right sides of the inspection aisle 4 so that an operator does not come into contact with various devices and cause an accident.

By wiring the low-voltage main line 8 through the lower part of the inspection aisle 4, the inspection board 4 is
Since the height H up to 1 is secured about 1900 mm,
The worker can work safely and without any trouble, and the workability is improved.

[0011]

As described above, the cubicle-type high-voltage power receiving equipment according to the present invention comprises a transformer at least inside a box,
A low-voltage panel installed on the opposite side of the transformer from the inspection walkway where workers can walk, a low-voltage device attached to the low-voltage panel, and a low-voltage trunk line connecting the secondary terminal of the transformer and the low-voltage device In the cubicle-type high-voltage power receiving equipment equipped with, the low-voltage main line is routed through the lower part of the inspection aisle, so that there is no trouble on the inspection aisle, the inspection work can be performed safely, and the workability is improved. This has the effect.
