A switch 43 for switching between the output of the AC / DC converter 3a and the storage battery 7 is provided. The storage battery 7 is configured to output the same voltage as the DC voltage generated by the AC / DC converter 3a, and is installed to supply electric power in the event of a power failure.

DC/DC盤5は、直流電圧変換装置5aを収容したケース11dに、複数の直流分岐ブレーカ52が組み付けられて構成され、直流分電盤4の直下に配置されている。直流電圧変換装置5aには、直流分電盤4の直流分岐電路の1つが接続され、交流/直流変換装置3aが生成する電圧より低い電圧(例えば12ボルト)の直流が生成されて出力され、この出力の先には複数の直流分岐ブレーカ52が接続されている。この直流分岐ブレーカ52の二次側には複数の直流分岐電路(低圧直流分岐電路)が接続されて、図示しない直流負荷まで配設されている。 The DC / DC board 5 is configured by assembling a plurality of DC branch breakers 52 into a case 11d accommodating a DC voltage converter 5a, and is arranged directly below the DC distribution board 4.

One of the branch electric circuits in the DC distribution board 4 is connected to the DC / AC converter 6a to generate and output AC power corresponding to the commercial power source 1, and the AC power is generated and output via the branch breaker 62, for example, an evacuation route. A specific load such as lighting in the corridor is sent to the connected branch electric circuit.

そして、これらのケース11、即ち交流分電盤2のケース11a、AC/DC盤3のケース11b、直流分電盤4のケース11c、DC/DC盤5のケース11d、DC/AC盤6のケース11eは、何れも住戸の壁内に一定間隔で設けられている間柱10の間の距離に合わせた同一の幅(例えば40cm)で形成されている。また、何れのケース11も、ケース11前面を閉塞する蓋板(図示せず)が蝶着されており、壁面内に収納されたケース11を閉塞した状態で前面が周囲の壁面と略面一になるよう構成されている。 Then, these cases 11, that is, the case 11a of the AC distribution board 2, the case 11b of the AC / DC board 3, the case 11c of the DC distribution board 4, the case 11d of the DC / DC board 5, and the DC / AC board 6. The cases 11e are all formed with the same width (for example, 40 cm) according to the distance between the inter-columns 10 provided in the wall of the dwelling unit at regular intervals. Further, in each case 11, a lid plate (not shown) that closes the front surface of the case 11 is winged, and the front surface is substantially flush with the surrounding wall surface in a state where the case 11 housed in the wall surface is closed. It is configured to be.

また、交流分電盤2、直流分電盤4、DC/DC盤5、DC/AC盤6は、それぞれのケース11の側面に分岐線を送出するための分岐線送出部12(12a〜12d)が開口形成されている。更に、交流分電盤2のケース11aには天面にも分岐線送出部12eが開口されている。
具体的に、図2に示すように交流分電盤2はケース11aの左側面に分岐線送出部12aが開口形成され、対応する左側の間柱10aにも開口部13が形成され、分岐線を間柱10aを介して側方へ送出可能に形成されている。また、直流分電盤4はケース11cの右側面に分岐線送出部12bが開口形成され、対応する右側の間柱10bにも開口部13が形成され、分岐線を左側の間柱10bを介して側方へ送出可能に形成されている。また、DC/DC盤5のケース11dは、右側面に分岐線送出部12cが開口形成され、対応する右側の間柱10bには開口部13が形成され、分岐線を右側の間柱10bを介して側方へ送出可能に形成されている。更に、DC/AC盤6はケース11eの左側面に分岐線送出部12dが開口形成され、対応する左側の間柱10aには開口部13が形成され、分岐線を左側の間柱10aを介して側方へ送出可能に形成されている。
Further, the AC distribution board 2, the DC distribution board 4, the DC / DC board 5, and the DC / AC board 6 have branch line transmission units 12 (12a to 12d) for transmitting branch lines to the side surfaces of the respective cases 11. ) Is formed. Further, the case 11a of the AC distribution board 2 is also provided with a branch line sending portion 12e on the top surface.
Specifically, as shown in FIG. 2, in the AC distribution board 2, a branch line sending portion 12a is formed on the left side surface of the case 11a, and an opening 13 is also formed on the corresponding left stud 10a to form a branch line. It is formed so that it can be sent laterally via the stud 10a. Further, in the DC distribution board 4, a branch line sending portion 12b is formed on the right side surface of the case 11c, an opening 13 is also formed in the corresponding right stud 10b, and the branch line is sided via the left stud 10b. It is formed so that it can be sent to the direction. Further, in the case 11d of the DC / DC board 5, a branch line sending portion 12c is formed on the right side surface, an opening 13 is formed in the corresponding right stud 10b, and the branch line is passed through the right stud 10b. It is formed so that it can be sent to the side. Further, in the DC / AC board 6, a branch line sending portion 12d is formed on the left side surface of the case 11e, an opening 13 is formed in the corresponding left stud 10a, and the branch line is sided via the left stud 10a. It is formed so that it can be sent to the direction.

この結果、交流分岐線と直流分岐線が左右で異なる方向へ送出され、図3に示すように、左側の間柱10aを介した左側を交流分岐線の専用エリア(ACエリア)E1とし、右側の間柱10bを介した右側を直流分岐線の専用エリア(DCエリア)E2とすることができ、左右で交流と直流の配線を完全分離することが可能となる。更に、交流分電盤2の上方空間も交流分岐線の専用エリア(ACエリア)E3として使用できる。
尚、直流分電盤4の下方となるDC/AC盤6の下方空間は、直流分岐線専用エリア(DCエリア)E4として使用してもよく、給電システム左右に加えて上下のエリアも完全に交流と直流で配線エリアを分離しても良い。
As a result, the AC branch line and the DC branch line are sent out in different directions on the left and right, and as shown in FIG. 3, the left side via the stud 10a on the left side is designated as the dedicated area (AC area) E1 of the AC branch line, and the right side. The right side via the stud 10b can be the dedicated area (DC area) E2 of the DC branch line, and the AC and DC wiring can be completely separated on the left and right. Further, the space above the AC distribution board 2 can also be used as a dedicated area (AC area) E3 for the AC branch line.
The space below the DC / AC board 6 below the DC distribution board 4 may be used as a DC branch line dedicated area (DC area) E4, and the upper and lower areas are completely in addition to the left and right areas of the power supply system. The wiring area may be separated by alternating current and direct current.

このように、交流分岐線の引き出し方向と直流分岐線の引き出し方向とは左右方向で異なるよう個々のケース11が形成されているため、縦方向に配置された交流分電盤2と直流分電盤4とはケース11から送出される分岐線が混在することが無くなり、誤配線を防止できる。また、間柱10間の上下方向に広い設置スペースを利用して各ケースを設置できるため、天井付近のみに設置する必要が無くなり設置作業がし易くなる。
また、上部に配置した交流分電盤2の上方を交流分岐線の空間にでき、誤配線の防止に有効である。
更に、2種類の電圧の直流分岐電路を配設できるため、電圧の異なる直流機器に対応できるし、直流分電盤及びDC/DC盤5の分岐線は同一方向に送出されるため、交流分岐線との誤配線を防止できる。
また、蓄電池7から商用電力に合わせた交流電力を生成して出力できるため、引き込んだ商用電力に停電が発生しても、避難路の照明等の特定の交流機器に対しては引き続き電力を供給できる。
In this way, since the individual cases 11 are formed so that the pull-out direction of the AC branch line and the pull-out direction of the DC branch line are different in the left-right direction, the AC distribution board 2 arranged in the vertical direction and the DC distribution board are distributed. Branch lines sent from the case 11 do not coexist with the board 4, and erroneous wiring can be prevented. Further, since each case can be installed by using a wide installation space in the vertical direction between the studs 10, it is not necessary to install the case only in the vicinity of the ceiling, and the installation work becomes easy.
Further, the space above the AC distribution board 2 arranged at the upper part can be used as a space for the AC branch line, which is effective in preventing erroneous wiring.
Further, since a DC branch electric circuit having two kinds of voltages can be arranged, it can be used for DC equipment having different voltages, and since the branch lines of the DC distribution board and the DC / DC board 5 are sent in the same direction, AC branching is possible. It is possible to prevent erroneous wiring with the wire.
In addition, since the storage battery 7 can generate and output AC power that matches the commercial power, even if a power failure occurs in the drawn commercial power, power will continue to be supplied to specific AC equipment such as evacuation route lighting. it can.

尚、上記実施形態では、給電システムの左側をACエリアE1、右側をDCエリアE2としているが、逆に形成しても良い。
また、直流分電盤4の直下にはDC/DC盤5を配置しているが、直流分電盤4の直下に空間を設けることができる場合は、直流分電盤4のケース11cの下面に分岐線送出部を設けて、下部空間をDCエリアE4として利用すると良く、給電システムの左右に加えて上下方向も完全に交流/直流で分離でき、誤配線を確実に防止できる。
In the above embodiment, the left side of the power supply system is the AC area E1 and the right side is the DC area E2, but they may be formed in reverse.
Further, although the DC / DC board 5 is arranged directly under the DC distribution board 4, if a space can be provided directly under the DC distribution board 4, the lower surface of the case 11c of the DC distribution board 4 is provided. It is preferable to provide a branch line sending portion in the area and use the lower space as the DC area E4. In addition to the left and right sides of the power supply system, the vertical direction can be completely separated by AC / DC, and erroneous wiring can be reliably prevented.
