[0021]

The front space can be provided integrally with the machine room in the storage box by the structure in which the internal space is separated longitudinally and longitudinally to form the front room and the machine room. For this reason,
It is not necessary to separately provide a front chamber and externally attach the same. This simplifies the manufacturing process and can be manufactured at a low cost. In addition, since there is no need to mount the front chamber during installation, installation is facilitated. The front room and the machine room are partitioned by a partition.
Since this partition has a door, it is possible to easily carry articles to the machine room. At that time, a space for the maintenance person can be provided between the entrance door of the front room and the partition, so that the work is easy. Furthermore, since there is a partition, even if the entrance door is open, entry of dust and the like can be prevented.

When the partition has a sliding door, no space is required for opening and closing the partition, so that a wasteful space is not provided in the front room or the machine room.

Further, the air conditioner, the duct for ventilating the inside and outside of the housing box, and the power line lead-in column are provided on the front end face and the rear end face of the housing box with parts for attaching articles protruding from the outer wall to the outside. Can be attached to this part. These are attached in a state where they protrude outside the outer wall of the storage box. However, since the projecting direction is the front-back direction of the storage box, it does not project from the carrier when transported by truck or the like. Therefore, they can be attached before transportation, which is convenient for manufacturing, transportation, and installation work.

An entrance door provided on the front end surface in the longitudinal direction of the storage box partitions the front chamber and the outside so as to be freely opened and closed. Also,
In the front room, an underground cable entrance is provided, from which an underground cable can be introduced. When this underground cable entrance is provided on the floor at a position from the left or right as viewed from the front end face side, maintenance personnel can easily work. In this case, when the hinge of the entrance door is provided on the left or right side where the underground cable entrance is provided,
The underground cable can be pulled out of the storage box in a straight line, which facilitates the work of drawing in the underground cable. In other words, since the entrance door is usually opened to the right, if the installation position of the underground cable facility is located on the left side when viewed from the entrance side, the thick underground cable can not be pulled out straight out and the cable startup Workability deteriorates. Conventionally, no special consideration has been given to such a problem. In the present invention, by employing the above-described configuration, this problem can be solved and workability can be improved.

The above-mentioned entrance door can be structured so as to be attached without providing a projection on the floor of the storage box. In this case, unevenness can be eliminated in the space inside the storage box. Therefore, it is easy to carry in the device.

The above-mentioned cable rack is formed by crossing channel materials, and the crossing portion has a structure in which a notch is provided in one channel material and the other channel material is fitted into the notch and assembled. Then, the thickness of the intersection of the channel materials can be reduced, and the internal space of the storage box can be used effectively.

Further, by mounting a heat insulating material on the outer wall, it is possible to cope with the temperature of the environment. in this case,
In order to satisfy the thermal conditions according to the outside air temperature conditions (highest and lowest temperatures) of the installation location, the thickness of the heat insulating material on the outer wall can be changed to make the storage box economical. However, by increasing the thickness of the heat insulating material on the floor surface than on the side and roof,
If the difference in the operating temperature condition of the facility is accommodated, it is possible to adjust the thickness of the heat insulating material on the floor surface portion. Thereby, the thickness of the heat insulating material can be made constant for the front end face, the rear end face, and the outer wall of the side face of the storage box, and the equipment installation area of the internal space of the storage box can be secured. Therefore, high-density mounting of the storage box is possible.

When a storage box installed outdoors is submerged, water permeates into the interior depending on the duration of the submersion. At this time, if the power supply unit is mounted on the lower part of the exchange device housing, the function stops and it takes time to recover. To cope with this, it is possible to cope with this by mounting the above-mentioned exchange unit and the power supply unit on a rack, and at this time, adopting a mounting structure in which the power supply unit is arranged at the top of the rack.

Further, a damper is provided in the above-mentioned duct, and this damper is lifted up through a temperature fuse, whereby
In the event of a fire, the damper can be automatically closed.
