Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a building provided with an AC-DC converter.

[0002]

2. Description of the Related Art Electricity is supplied to a building of an electric power consumer by alternating current in consideration of electric power loss at the time of electric power transmission. Even inside the building, electric power is distributed by a distribution board to generate electric power by alternating current to an outlet. Was being supplied.

Conventionally, an AC-DC converter for converting alternating current into direct current is provided for each electric device.

[0004]

However, the provision of an AC-DC converter for converting alternating current into direct current for each electric device as in the prior art causes a rise in the price of the electric device, and also increases the price of the electric device. Will also increase in size.

Further, in general, when power is supplied to an outlet through an alternating current having a high voltage, a fire may occur when a short-circuit accident such as a lightning strike or a direct contact between distribution lines occurs.

Therefore, according to the present invention, AC-DC is provided for each electric device.
It is an object of the present invention to eliminate the need for a converter and to provide a building that does not cause a fire in the event of a lightning strike or a short-circuit accident such as direct contact between distribution lines.

[0007]

In order to solve the above problems, the present invention provides a building characterized in that an AC-DC converter is provided at least in front of an outlet.

The AC-DC converter may be of any type as long as it can convert alternating current into direct current, and examples thereof include a dropper type and a switching type.

By providing such an AC-DC converter in front of the outlet, it becomes unnecessary to equip each electric device with the AC-DC converter.

Although the place where the AC-DC converter is installed can be arbitrarily selected, considering that the purpose of the present invention is to prevent fire, the AC-DC converter is provided with a breaker. It is desirable to prepare for the distribution board.

By thus converting AC into DC in the distribution board, it is possible to supply electric power to the outlet with DC having a low voltage, so that it is possible to prevent fire.

Here, a main switch breaker, an earth leakage breaker, and a circuit breaker are generally housed in the distribution board. The place where the DC voltage power supply storage is installed is as follows. It is a design item that can be arbitrarily selected.

The fire prevention can be further strengthened by applying a fireproof treatment between the breaker and the AC-DC converter.

Here, when an AC-DC converter is provided in the distribution board in which the breaker is housed, the distribution board itself can be insulated to prevent fire.

The building includes all buildings such as buildings, condominiums, apartments and detached houses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the present invention.
It is a schematic front view of a house 100 having an AC-DC converter 101.

Electric power sent from the power transmission line 102 is taken indoors via the meter 103.

Electric power taken indoors is distributed to the distribution board 10.
4 is connected to the main open / close breaker 105, and then supplied to the outlet 108 and the lighting 109 through the leakage preventive breaker 106 and the circuit breaker 107.

In this embodiment, in the distribution board 104, after passing through the circuit breaker 107, AC-
After the power is changed from alternating current to direct current by the DC converter 101, it is supplied to the outlet 108 and the lighting 109.

As shown in FIG. 2, the distribution board 104.
The main opening / closing breaker 105 and the leakage prevention breaker 10
6. A circuit breaker 107 is provided.

The main opening / closing breaker 105 is designed to disconnect the circuit when more electric power than the electric power contracted with the electric power company is used, and the leakage prevention breaker 106 is
It is designed to disconnect the circuit when a leak is detected.
Furthermore, the circuit breaker 107 disconnects the circuit when the amount of power used is larger than the amount of power assigned to each circuit.

In the present embodiment, the AC-DC converter 101 is connected to the circuit breaker 107 of the distribution board 104 configured as described above, and the power supplied by AC is converted into DC and each It is supplied to the outlet 108 and the like.

In this embodiment, since the electric power is converted from AC to DC after the circuit breaker 107 is added, the AC-
The DC converter 101 is required, for example, between the meter 105 and the main opening / closing breaker 105, between the main opening / closing breaker 105 and the earth leakage prevention breaker 106, or between the earth leakage preventing breaker 106 and the circuit breaker 10.
If an AC-DC converter 101 is provided between the
The AC-DC converter 101 can convert AC to DC.

Further, in this embodiment, the AC-DC converter 101 is connected to all the circuit breakers 107, but for example, a specific circuit breaker 107 is used.
Is connected to the AC-DC converter 101, and the other circuit-specific breaker 107 is not connected to the AC-DC converter 101, so that power is supplied to a specific circuit by direct current and other circuits are connected to the circuit breaker 107. It is also possible to supply power by alternating current.

The AC-DC converter 101 used in the present embodiment is of a switching type.
It is also possible to use a dropper type.

Further, what kind of voltage the power supplied by direct current is to be supplied is a design matter which can be selected at any time, but for example, it is supplied at a constant voltage of 48 V (volt) or 24 V (volt). By doing so, it is possible to reduce fires due to electric leakage and short-circuit current.

In the present embodiment, the occurrence of fire is also prevented by forming the distribution board 104 itself with a non-conductive and flame-retardant resin.

[0028]

Since the present invention is constructed as described above, it is not necessary to prepare an AC-DC converter for each electric device, and it is possible to prevent a fire due to an electric leakage or a short circuit current.
