Abstract

PROBLEM TO BE SOLVED: To prevent a receiving apparatus from having insulation deterioration very easily and at a low cost by preventing invasion of rainwater or ice and snow from venting holes even after cubicle type high-voltage receiving equipment is installed on a field. SOLUTION: This cubicle type high-voltage receiving equipment 1 consists of a channel base 2 whose venting holes 2a protrude at appropriate intervals, a case 3 fixed on the channel base 2, a roof body 4 fixed on the case 3, and a pentroof 5 whose venting holes 5a are drilled at appropriate intervals. Magnet sheets 6, 7 are attached onto the channel base 2 and the pentrooof 5 to block the venting holes 2a, 5a.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a ventilation hole of a cubicle type high-voltage power receiving equipment for accommodating various power receiving devices.

[0002]

2. Description of the Related Art Conventionally, the structure of a vent of a cubicle-type high-voltage power receiving facility for accommodating various power receiving devices has been shown in FIG. That is, the cubicle-type high-voltage power receiving equipment 31
Channel base 3 having ventilation holes 32a formed at appropriate intervals
2 and a box 3 mounted and fixed on the channel base 32
3, a roof 34 mounted and fixed on the box 33, and an eave portion 35 having ventilation holes 35a formed at appropriate intervals, for example, as shown in FIG. 2 of JP-A-10-108308. In this case, two eaves are placed one on top of the other, and one of them is slid to close the ventilation hole, to prevent infiltration of rainwater, ice and snow, and to prevent insulation deterioration of the power receiving device.

[0003]

However, according to the above-mentioned conventional cubicle-type high-voltage power receiving equipment, it is extremely difficult to provide the second eaves plate on the eaves after the cubicle-type high-voltage power receiving equipment is once installed on site. There was a disadvantage.

[0004]

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 a cubicle-type high-voltage power receiving equipment that can be easily and inexpensively formed through a vent hole even after the cubicle-type high-voltage power receiving equipment is installed on site. Provided is a cubicle-type high-voltage power receiving equipment capable of preventing infiltration of rainwater, ice and snow, and preventing insulation deterioration of a power receiving device, and a channel base provided with ventilation holes at least at appropriate intervals, and mounted on the channel base. In a cubicle-type high-voltage power receiving facility that stores various power receiving devices configured by a fixed box, a roof mounted and fixed on the box, and an eave portion having a ventilation hole at an appropriate interval, the channel base and By attaching a detachable magnet sheet to the eave portion, the vent hole of the channel base and the vent hole of the eave portion are closed.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION By attaching a magnet sheet to a channel base and an eave portion of a cubicle type high-voltage power receiving facility, the air holes formed in the channel base and the eaves formed in the eave portion are completely closed. This prevents rainwater, ice and snow from entering from this part, thereby preventing insulation deterioration of the power receiving device.

[0006]

FIG. 1 shows an embodiment of a cubicle-type high-voltage power receiving equipment according to the present invention. Hereinafter, the present invention will be described with reference to the drawings.

The cubicle-type high-voltage power receiving equipment 1 comprises a channel base 2 having ventilation holes 2a formed at appropriate intervals, a box 3 mounted and fixed on the channel base 2, and a roof mounted and fixed on the box 3 It comprises a body 4 and an eave portion 5 having ventilation holes 5 a formed at appropriate intervals, and magnet sheets 6 and 7 are attached to the channel base 2 and the eave portion 5.

By attaching magnet sheets 6 and 7 to the channel base 2 and the eaves 5 of the cubicle-type high-voltage power receiving equipment 1, a vent 2a formed in the channel base 2 and a vent 5a formed in the eaves 5 are attached. Completely occlude,
This prevents rainwater, ice and snow from entering from this part, thereby preventing insulation deterioration of the power receiving device.

When the magnet sheets 6 and 7 are not used, the door 3 of the box 3 of the cubicle-type high-voltage power receiving equipment 1
If it is affixed to the back of a, etc., it can be easily stored and will not be lost.

The shapes and dimensions of the magnet sheets 6 and 7 are not limited to the present embodiment, but can be changed as appropriate without departing from the spirit of the present invention.

[0011]

As described above, the cubicle-type high-voltage power receiving equipment according to the present invention comprises: a channel base having ventilation holes formed at least at appropriate intervals; a box mounted and fixed to the channel base; A roof mounted and fixed on the
In a cubicle-type high-voltage power receiving facility that stores various power receiving devices configured with an eave portion having ventilation holes formed at appropriate intervals,
By adhering a detachable magnet sheet to the channel base and the eave part to close the vent hole of the channel base and the eave part of the eave part, even after installing the cubicle type high-voltage power receiving equipment on site, extremely There is an effect that it is possible to easily and inexpensively prevent rainwater or ice and snow from entering from the ventilation holes and prevent insulation deterioration of the power receiving device.
