第１コネクタ２１は、複数の負荷機器８２を制御する制御機器８１との間で有線通信を行うための第１通信ケーブル７１を着脱自在に接続する（図２参照）。ところで、制御機器８１は、電力会社からの情報（例えば、節電要請）に基づいて複数の負荷機器８２の動作を制御する電気機器である。第１通信アダプタ２と制御機器８１との間の通信方式は、例えば有線ＬＡＮ（Ｌｏｃａｌ Ａｒｅａ Ｎｅｔｗｏｒｋ）等の有線通信である。   The first connector 21 detachably connects a first communication cable 71 for performing wired communication with a control device 81 that controls a plurality of load devices 82 (see FIG. 2). By the way, the control device 81 is an electrical device that controls the operation of the plurality of load devices 82 based on information from the electric power company (for example, a power saving request). The communication method between the first communication adapter 2 and the control device 81 is, for example, wired communication such as a wired LAN (Local Area Network).

第２コネクタ２２は、配電ケーブルを介して計測用アダプタ５と電気的に接続されるためのレセプタクルコネクタである。第１通信アダプタ２は、第２コネクタ２２に接続されている電源ケーブルを介して、計測用アダプタ５から直流電力が供給されて動作する。   The second connector 22 is a receptacle connector for being electrically connected to the measurement adapter 5 via a power distribution cable.

The first communication adapter 2 is connected to the measurement adapter 5 via a communication cable, thereby receiving the measurement results of the power (power consumption) of the main distribution line 61 and the branch distribution line 62 from the measurement adapter 5. Can do. The standard for communication between the first communication adapter 2 and the measurement adapter 5 is preferably serial communication, for example.

第２通信アダプタ３は、合成樹脂製であって、第１通信アダプタ２と前後に重なって結合される段部３３を有する矩形の箱形に形成される筐体を備える。また、第２通信アダプタ３は、第４コネクタ３１と、第５コネクタ３２とを備える。第２通信アダプタ３は、スマートメータ６との間で通信する機能を有している。第２通信アダプタ３とスマートメータ６との間の通信方式は、電波を媒体とする無線通信であってもよい。また、第２通信アダプタ３とスマートメータ６との間の通信方式は、第４コネクタ３１を利用したＰＬＣ（Ｐｏｗｅｒ Ｌｉｎｅ Ｃｏｍｍｕｎｉｃａｔｉｏｎ）通信でもよい。ＰＬＣ通信を行う場合、第２通信アダプタ３は、ＰＬＣケーブルを介して主幹ブレーカ１４の一次側端子１４１又は二次側端子に接続される。第５コネクタ３２は、第１通信アダプタ２の上方背面に設けられているコネクタと機械的に結合される。これにより、第２通信アダプタ３は、第１通信アダプタ２と電気的に接続されて、第１通信アダプタ２と通信が可能になる。さらに、第２通信アダプタ３には、第１通信アダプタ２から電力が供給される。   The second communication adapter 3 is made of a synthetic resin, and includes a casing formed in a rectangular box shape having a step portion 33 that is coupled to the first communication adapter 2 so as to overlap in the front-rear direction. The second communication adapter 3 includes a fourth connector 31 and a fifth connector 32. The second communication adapter 3 has a function of communicating with the smart meter 6. The communication method between the second communication adapter 3 and the smart meter 6 may be wireless communication using radio waves as a medium. The communication method between the second communication adapter 3 and the smart meter 6 may be PLC (Power Line Communication) communication using the fourth connector 31. When performing PLC communication, the 2nd communication adapter 3 is connected to the primary side terminal 141 or the secondary side terminal of the main breaker 14 via a PLC cable. The fifth connector 32 is mechanically coupled to a connector provided on the upper back surface of the first communication adapter 2. Thereby, the 2nd communication adapter 3 is electrically connected with the 1st communication adapter 2, and communication with the 1st communication adapter 2 is attained. Furthermore, power is supplied from the first communication adapter 2 to the second communication adapter 3.

第３通信アダプタ４は、合成樹脂製であって、第１通信アダプタ２と前後に重なって結合する段部４１を備える矩形の箱形に形成される筐体を備える。また、第３通信アダプタ４は、第６コネクタ４２と、第７コネクタ４３と、第１接続部４４とを備える。第１接続部４４は、ケーブルを介して外部装置、例えば、パルス発信器付き流量計やガスメータと接続される。第６コネクタ４２は、第１通信アダプタ２の下方背面に設けられているコネクタと機械的に結合する。これにより、第３通信アダプタ４は、第１通信アダプタ２と電気的に接続されて通信が可能になる。例えば、第３通信アダプタ４は、ガスメータや流量計からパルス信号を受信し、第６コネクタ４２を介して第１通信アダプタ２にパルス信号を送信する。第１通信アダプタ２は、第３通信アダプタ４から受信するパルスをカウントすることで、ガスや水道の使用量を計測することが可能になる。また、第７コネクタ４３は、配電ケーブルを介して計測用アダプタ５と電気的に接続可能なレセプタクルコネクタである。第３通信アダプタ４は、第７コネクタ４３に接続される電源ケーブルを介して計測用アダプタ５から直流電力が供給されて動作する。   The third communication adapter 4 is made of a synthetic resin and includes a casing formed in a rectangular box shape including a step portion 41 that overlaps with the first communication adapter 2 in the front-rear direction. The third communication adapter 4 includes a sixth connector 42, a seventh connector 43, and a first connection unit 44. The first connection unit 44 is connected to an external device such as a flow meter with a pulse transmitter or a gas meter via a cable. The sixth connector 42 is mechanically coupled to a connector provided on the lower back surface of the first communication adapter 2. As a result, the third communication adapter 4 is electrically connected to the first communication adapter 2 to enable communication. For example, the third communication adapter 4 receives a pulse signal from a gas meter or a flow meter, and transmits the pulse signal to the first communication adapter 2 via the sixth connector 42. The first communication adapter 2 can measure the amount of gas and water used by counting the pulses received from the third communication adapter 4. The seventh connector 43 is a receptacle connector that can be electrically connected to the measurement adapter 5 via a power distribution cable. The third communication adapter 4 operates by being supplied with DC power from the measurement adapter 5 via a power cable connected to the seventh connector 43.

第３通信アダプタ４が筐体１１に取り付けられている場合、計測用アダプタ５は、第３通信アダプタ４に直流電力を供給する。そして、第３通信アダプタ４は、第６コネクタ４２を介して第１通信アダプタ２に電力を供給する。   When the third communication adapter 4 is attached to the housing 11, the measurement adapter 5 supplies DC power to the third communication adapter 4. The third communication adapter 4 supplies power to the first communication adapter 2 via the sixth connector 42.

ただし、第３通信アダプタ４が筐体１１に取り付けられていない場合、計測用アダプタ５は、第１通信アダプタ２に直流電力を供給する。   However, when the third communication adapter 4 is not attached to the housing 11, the measurement adapter 5 supplies DC power to the first communication adapter 2.

計測用アダプタ５は、合成樹脂製であって、矩形の箱形に形成された筐体を備える。また、計測用アダプタ５は、電圧変換機能と、計測機能とを備える。   The measuring adapter 5 is made of a synthetic resin and includes a housing formed in a rectangular box shape. The measurement adapter 5 includes a voltage conversion function and a measurement function.

計測用アダプタ５の電圧変換機能は、交流電圧（例えば、１００Ｖ）を直流電圧に変換するスイッチング電源回路を備えている。これにより、計測用アダプタ５は、分岐ブレーカ１５１から交流電圧を入力し、直流電圧に変換して、第１通信アダプタ２又は第３通信アダプタ４に直流電圧を出力する。   The voltage conversion function of the measurement adapter 5 includes a switching power supply circuit that converts an AC voltage (for example, 100 V) into a DC voltage. As a result, the measurement adapter 5 receives the AC voltage from the branch breaker 151, converts it to a DC voltage, and outputs the DC voltage to the first communication adapter 2 or the third communication adapter 4.

計測用アダプタ５の計測機能は、主幹配電線６１に流れる電流及び電圧を計測し、主幹配電線６１の電力（消費電力）を演算する。また、計測用アダプタ５は、分岐配電線６２の各々に流れる電流及び電圧を計測し、各分岐配電線６２の電力（消費電力）を演算する。ただし、計測用アダプタ５の代わりに電流計測器を用いて分岐配電線６２の各々に流れる電流及び電圧を計測し、電力（消費電力）を演算してもよい。ところで、ここでいう電流計測器は、導電バーに直接取り付け可能な電流計であって、演算結果を通信ケーブルを介して計測用アダプタ５に送信することができる。   The measurement function of the measurement adapter 5 measures the current and voltage flowing through the main distribution line 61 and calculates the power (power consumption) of the main distribution line 61. The measurement adapter 5 measures the current and voltage flowing through each branch distribution line 62 and calculates the power (power consumption) of each branch distribution line 62. However, the current and voltage flowing through each of the branch distribution lines 62 may be measured using a current measuring instrument instead of the measuring adapter 5 to calculate the power (power consumption). By the way, the current measuring device here is an ammeter that can be directly attached to the conductive bar, and can send the calculation result to the measuring adapter 5 via the communication cable.

ところで、筐体１１は、電流制限器（リミッタ）を収納するためのスペース（リミッタスペース）が設けられている場合もある。   By the way, the housing | casing 11 may be provided with the space (limiter space) for accommodating a current limiter (limiter).

最後に、第１通信ケーブル７１の配線及び通線孔１６について、図１を参照して説明する。   Finally, the wiring of the first communication cable 71 and the through hole 16 will be described with reference to FIG.

筐体１１内部は、図１に示すように、第１の領域１２と第２の領域１３に区分けされる。第１の領域１２は、高電圧・高電流を取り扱う主幹ブレーカ１４及び複数の分岐ブレーカ１５を収納する。第２の領域１３は、低電圧・低電流で動作する、第１通信アダプタ２と、第２通信アダプタ３と、第３通信アダプタ４と、計測用アダプタ５とを収納する。第２の領域１３は、筐体１１の左側にＬ字型に設けられる。第１通信アダプタ２と第２通信アダプタ３と第３通信アダプタ４と計測用アダプタ５はそれぞれ、互いに着脱自在に機械的に結合されている。第２の領域１３には、上端から第２通信アダプタ３、第１通信アダプタ２、第３通信アダプタ４が縦に並んで配置されている。また、計測用アダプタ５はＬ字の短辺にあたる筐体１１の下部に配置される。   As shown in FIG. 1, the interior of the housing 11 is divided into a first area 12 and a second area 13. The first region 12 houses a main breaker 14 that handles high voltage and high current and a plurality of branch breakers 15. The second region 13 accommodates the first communication adapter 2, the second communication adapter 3, the third communication adapter 4, and the measurement adapter 5 that operate at a low voltage and a low current. The second region 13 is provided in an L shape on the left side of the housing 11. The first communication adapter 2, the second communication adapter 3, the third communication adapter 4, and the measurement adapter 5 are mechanically coupled to each other in a detachable manner. In the second region 13, the second communication adapter 3, the first communication adapter 2, and the third communication adapter 4 are arranged vertically from the upper end. Further, the measurement adapter 5 is arranged at the lower part of the housing 11 corresponding to the short side of the L-shape.

第１コネクタ２１は、第１通信アダプタ２の正面左下に設けられており、差込口が下方を向いて設置されている。第２の領域１３において、第３通信アダプタ４のすぐ下には、筐体１１の背板１１１に通線孔１６が設けられている。通線孔１６は、背板１１１を貫通する矩形の孔である。第１コネクタ２１に接続される第１通信ケーブル７１は、通線孔１６を通って筐体１１の背後に配線される。   The 1st connector 21 is provided in the lower left front of the 1st communication adapter 2, and the insertion slot is installed in the downward direction. In the second region 13, a through hole 16 is provided in the back plate 111 of the housing 11 immediately below the third communication adapter 4. The through hole 16 is a rectangular hole that penetrates the back plate 111. The first communication cable 71 connected to the first connector 21 is wired behind the housing 11 through the through hole 16.

筐体１１の内部において、第３通信アダプタ４の下方には、空間１７が存在している。ゆえに、第１通信ケーブル７１は、第１コネクタ２１の差込口から通線孔１６までの距離よりも長い状態で筐体１１内に露出していても、第１通信ケーブル７１を空間１７に引き回すことが可能である。したがって、第１通信ケーブル７１は、第１の領域１２を通らずに通線孔１６に通される。また、第１コネクタ２１の差込口が下方に向いていることで、第１通信ケーブル７１に張力等によるストレスを与えることなく、第１通信ケーブル７１は、第２の領域１３内に配線されることが可能である。さらに、第１コネクタ２１は第２の領域１３の左端に設けられているので、第１コネクタ２１が第１通信アダプタ２の正面下方右側にある場合と比較して、第１通信ケーブル７１は、第１の領域１２に入り難い。したがって、第１通信ケーブル７１は、第２の領域１３内で配線され、通線孔１６を通って筐体１１の背後へと配線されるので、高電圧・高電流によるノイズの影響を受け難い。   Inside the casing 11, a space 17 exists below the third communication adapter 4. Therefore, even if the first communication cable 71 is exposed in the housing 11 in a state longer than the distance from the insertion port of the first connector 21 to the through hole 16, the first communication cable 71 is placed in the space 17. Can be routed. Accordingly, the first communication cable 71 is passed through the through hole 16 without passing through the first region 12. Further, since the insertion port of the first connector 21 faces downward, the first communication cable 71 is wired in the second region 13 without applying stress due to tension or the like to the first communication cable 71. Is possible. Furthermore, since the first connector 21 is provided at the left end of the second region 13, the first communication cable 71 is compared with the case where the first connector 21 is on the lower right side of the front of the first communication adapter 2. It is difficult to enter the first region 12. Accordingly, the first communication cable 71 is wired in the second region 13 and is wired to the back of the housing 11 through the through hole 16, so that it is hardly affected by noise due to high voltage and high current. .

ただし、通線孔１６が設けられる場所は、第２の領域１３内であれば、本実施形態に限定されない。また、第１通信ケーブル７１は、第１通信アダプタ２と接続されていればよく、本実施形態のように必ずしも第１コネクタ２１を用いて接続する必要はない。   However, the place where the through hole 16 is provided is not limited to the present embodiment as long as it is within the second region 13. Moreover, the 1st communication cable 71 should just be connected with the 1st communication adapter 2, and does not necessarily need to connect using the 1st connector 21 like this embodiment.

本実施形態の分電盤１は、筐体１１と、主幹ブレーカ１４と、複数の分岐ブレーカ１５と、通信アダプタ（第１通信アダプタ２）とを備える。筐体１１内部は、主幹ブレーカ１４と複数の分岐ブレーカ１５が収納される第１の領域１２と、通信アダプタ（第１通信アダプタ２）が収納される第２の領域１３とに区分けされる。通信アダプタ（第１通信アダプタ２）は、外部装置（制御機器８１）との間で、通信ケーブル（第１通信ケーブル７１）を介して有線通信をおこなうように構成されている。第２の領域１３には、通信ケーブル（第１通信ケーブル７１）を筐体１１の外部から通す通線孔１６が設けられている。   The distribution board 1 of this embodiment includes a housing 11, a main breaker 14, a plurality of branch breakers 15, and a communication adapter (first communication adapter 2). The inside of the housing 11 is divided into a first area 12 in which the main breaker 14 and the plurality of branch breakers 15 are accommodated, and a second area 13 in which the communication adapter (first communication adapter 2) is accommodated. The communication adapter (first communication adapter 2) is configured to perform wired communication with an external device (control device 81) via a communication cable (first communication cable 71). The second region 13 is provided with a through hole 16 through which a communication cable (first communication cable 71) passes from the outside of the housing 11.

したがって、本実施形態の分電盤は、第１通信ケーブル７１を第２の領域１３内で配線するので、住宅用分電盤は、第１通信ケーブル７１に高電圧・高電流によるノイズの影響を受け難くすることができる。   Therefore, since the distribution board of this embodiment wires the 1st communication cable 71 in the 2nd area | region 13, the distribution board for houses has the influence of the noise by high voltage and high current on the 1st communication cable 71. It can be made difficult to receive.
