Description

[Detailed Description of the Invention] This invention relates to a substation device that prevents noise from a transformer installed in a cubicle or building from leaking to the outside, and aims at a ventilation effect.

In order to prevent the noise from the transformer from leaking outside, the transformer room can be completely sealed with a soundproof wall, but since the transformer itself generates heat in addition to noise, it is necessary to provide ventilation.

For this reason, in the past, ventilation holes were provided in soundproof walls and sound-deadening boxes were installed in these holes to prevent noise from escaping.

The inside of the sound deadening box has a labyrinth structure, which has a sound deadening effect, but on the other hand, the ventilation effect is not sufficient because air circulation becomes poor.

This invention was proposed with the above points in mind and for the purpose of soundproofing and ventilation, and examples will be described below in detail with reference to the drawings.

Figures 1 and 2 are a plan view and a side view, respectively, showing an embodiment of the present invention, in which 1 is a side wall of a building or cubicle, etc.;
Reference numeral 3 denotes a partition wall for dividing the interior, which constitutes chambers 4, 5, and 6.

A radiator 7, a transformer main body 8, a switchgear 9, etc. are housed and installed in each room.

10 is an intake duct provided along the side wall 1 in the chamber 6;
11 is an intake port, 12 is an underfloor pit, and 13 is a cable pit.

14 is a duct for leading out the secondary cable of the transformer main body 8, and a wire mesh 15 is provided in a part of the duct.

16 is a ventilation fan provided in the partition wall 3.

17 is an exhaust port, and 18 is a ventilation port. In addition, the intake port 11
, intake duct 10, underfloor pit 12, cable pit 1
3 and the wire mesh 15 of the duct 14 are in communication with each other.

By operating the ventilation fan 16, air is circulated from the chamber 5 to the chamber 6, and the noise from the transformer main body 8 in the chamber 5 is reduced by the chamber 6.

In other words, the cold air taken in from the intake port 11 passes through the intake duct 10 which is not affected by the temperature of the room 6, and is routed through the wire mesh 15 of the underfloor pit 12, cable pit 13, and duct 14 into the room.
On the other hand, the high temperature air in the upper layer of the chamber 5 is discharged to the outside from the exhaust port 17 via the chamber 6 by the ventilation fan 16.

In the case of this embodiment, in addition to the effects described later, there is an effect that the cables in the underfloor pit 12, cable pit 13, and duct 14 can be cooled by passing cold air.

Further, although the room 4 performs natural ventilation through the ventilation port 18 independently of the rooms 5 and 6, the room 4 is not necessary when the transformer main body 8 and the radiator 7 are integrated.

FIG. 3 shows another embodiment of the present invention, and this embodiment is similar to the first embodiment.
, 2 is adopted when the underfloor pit 12 shown in FIGS.

Therefore, the outside air from the intake port 11 is transferred to the intake duct 10 and the opening 1
9 directly into the room 5, and further the ventilation fan 1 of the room 5.
6 and is discharged to the outside from the exhaust port 17 via the chamber 6.

In addition, as mentioned above, since the underfloor pit 12 is not provided,
The cable pit 13 communicating with the secondary cable lead-out duct 14 is led out in a direction opposite to that shown in FIGS. 1 and 2.

In addition, in the case of this embodiment, since the cables in the duct 14 and cable pit 13 are not cooled, the duct 1
It is not necessary to provide the wire mesh 15 on the wire mesh 4.

As described above, according to the present invention, the transformer that generates noise and heat is stored separately from other equipment, and the intake and exhaust in the transformer storage room is carried out through the adjacent room, thereby improving ventilation and soundproofing. A highly effective substation device can be obtained.
