[0002]

[Prior Art]

 In a large-scale building, the power received by high voltage or extra high voltage is stepped down to 200V class or 400V class by the main power receiving equipment and wired separately to each block (for example, each floor, each business section) in the building. Further, each block is provided with a distribution electrical equipment including a power transformer for distribution (hereinafter simply referred to as a transformer) and a distribution board, and the load of each terminal from the electrical equipment to a 200V class or a 100V class. Supplying voltage power. In the conventional electrical equipment for distribution, a distribution board and a transformer serving as a power source of the distribution board are arranged side by side in the lateral direction, and the two are connected by wiring.

In addition, when a telephone is pulled into a building, it is necessary to provide a telephone terminal board equipped with terminals, a protector, etc. for relaying between the pulled-in office line and indoor wiring. , Conventionally, this telephone terminal board was installed separately from the electrical equipment for distribution.

[0004]

[Problems to be solved by the device]

 In conventional electrical equipment for distribution, transformers and distribution boards are installed side by side separately and telephone terminal boards are installed separately from the equipment for distribution. However, there was a problem that this hindered the effective use of the valuable space in the building.

Further, recently, it has been emphasized to improve the comfort of the environment in the building, but the transformers, the distribution boards, or the telephone terminal boards that are distributed and distributed make the occupants feel uncomfortable. , There was also a problem that it becomes an obstacle in improving the comfort of the environment in the building.

An object of the present invention is to compactly combine a transformer, a distribution board, and a telephone terminal board to reduce the floor area occupied by the power distribution equipment and the telephone terminal board, and to achieve harmony with the environment inside the building. It is to provide electrical equipment for distribution and telephone communication that can be easily implemented.

[0007]

[Means for Solving the Problems]

 The present invention is a compact combination of a distribution board, a transformer for the power supply of the distribution board, and a telephone terminal board.

In the present invention, a vertically long case whose depth dimension is set smaller than the width dimension is used, and in this case, the transformer storage room, the distribution board storage room, and the telephone terminal board storage room are partitioned from each other. And are installed in order from the bottom to the top, and a vertical duct extending vertically at least on the side of the transformer storage room and the distribution panel storage room is provided. The transformer and distribution board are stored in the transformer storage room and the distribution board storage room, respectively, and the telephone terminal board is stored in the telephone terminal board storage room.

A partition plate made of an electromagnetic shield is disposed in the telephone terminal board storage chamber so as to divide the interior into two in the depth direction, and the telephone terminal board is disposed on the front side of the partition board. Preferably.

Further, it is preferable that the interior of the vertical duct is divided into a duct space for storing a power cable and a duct space for storing a communication cable by an electromagnetic shield plate.

The above vertical duct may be provided on only one side in the width direction of the case, or may be provided on both sides.

The case may have a structure in which each storage chamber and a vertical duct are formed by partitioning the inside of the box with a partition wall, or a structure in which unit containers forming each storage chamber and duct are combined and integrated. But it's okay.

[0013]

[Action]

 As described above, by arranging the transformer, distribution board, and telephone terminal board side by side in the vertical direction, the whole can be compacted, and therefore the space for the distribution equipment and telephone terminal board to be reduced in the building. Can be planned.

With the above-described configuration, the wiring work for connecting the distribution board and the transformer can be performed in the assembly factory, and thus the troublesome wiring work at the installation site can be omitted.

Further, when the heavy transformer is arranged in the lower portion as described above, the position of the center of gravity can be lowered, so that high stability can be obtained and safety against an earthquake or the like can be enhanced.

Further, when the vertical duct is provided as described above, the space in the vertical duct can be used as a wiring storage space, so that the wirings can be arranged without being exposed to the outside, and the appearance can be improved. can do.

In particular, when the inside of the vertical duct is divided into a duct for storing the power cable and a duct for storing the communication cable by the electromagnetic shielding plate, when the power cable and the communication cable are routed through the inside of the vertical duct, interference occurs between both cables. It is possible to prevent noise and hum from being introduced into the telephone line.

If the telephone terminal board storage room is divided into two rooms by a partition plate made of an electromagnetic shield, a power cable can be introduced into the telephone terminal board storage room without affecting the telephone line. The space inside the telephone terminal board storage room can be used for pulling in or pulling out the power cable, and the flexibility of wiring can be increased.
