Description

本発明は、電力量計から分電盤に至る幹線に電気自動車の充電器を配置した配線システムに関する。   The present invention relates to a wiring system in which a charger for an electric vehicle is arranged on a main line from a watt hour meter to a distribution board.

電気自動車の充電設備を戸建住宅に設置する場合、従来は図５に示すように住戸Ｈ内に設置されている分電盤１２から分岐配線Ｌ１１を引き出し、壁面に穴を開ける等して駐車エリア近くまで配設し、住戸外壁或いは自立する形で電気自動車Ｖを充電するための充電器１３に分岐配線Ｌ１１を接続していた（例えば、特許文献１参照）。   When installing a charging facility for an electric vehicle in a detached house, conventionally, the branch wiring L11 is drawn from the distribution board 12 installed in the dwelling unit H as shown in FIG. The branch wiring L11 was connected to the charger 13 for charging the electric vehicle V in the form of being arranged near the area and dwelling on the outer wall of the dwelling unit or standing on its own (see, for example, Patent Document 1).

特開２０１３−３１２７０号公報Japanese Unexamined Patent Publication No. 2013-31270

上述したように、戸建住宅では電気自動車充電のための電源設備である充電器１３は住宅内の分電盤１２から引き出されて配設されたため、商用電力系統からの引き込み線が接続される電力量計１１が電気自動車充電のための充電器１３の近くに設置されていても、電力量計１１から住戸内の分電盤１２まで幹線を配設し、分電盤１２において分岐ブレーカ等を介した分岐配線Ｌ１１が充電器１３まで配設された。その際、電気自動車充電のための電線は例えば３０アンペアと大きな電流容量を有する太い専用配線となるため、駐車場まで長い専用配線が敷設されたし、分電盤１２の変更や追加も発生したため、コスト増を招いていた。   As described above, in the detached house, the charger 13 which is a power supply facility for charging the electric vehicle is drawn out from the distribution board 12 in the house and is thus connected to the lead-in line from the commercial power system. Even if the watt hour meter 11 is installed near the charger 13 for charging the electric vehicle, a trunk line is arranged from the watt hour meter 11 to the distribution board 12 in the dwelling unit, and a branch breaker or the like is provided in the distribution board 12. A branch line L11 through the battery is disposed up to the charger 13. At that time, electric wires for charging the electric vehicle are, for example, thick dedicated wiring having a large current capacity of 30 amperes, so long dedicated wiring is laid down to the parking lot, and distribution board 12 has been changed or added. , Which led to an increase in costs.

一方で、車庫は住戸玄関に隣接して或いは玄関前に設けられる場合が多いし、電力量計１１も検針し易い場所に設置されるため、玄関の近くの壁面に設置される場合が多い。そのため、必然的に充電器１３も電力量計１１の近くに設置される場合が多かったが、上述したように両者は分電盤１２を介して接続され、直接接続されることがなかった。   On the other hand, the garage is often provided adjacent to or in front of the entrance of the dwelling unit, and the watt-hour meter 11 is also installed in a place where meter reading is easy to perform, so it is often installed on the wall near the entrance. For this reason, the charger 13 is inevitably installed near the watt hour meter 11, but as described above, both are connected via the distribution board 12 and are not directly connected.

そこで、本発明はこのような問題点に鑑み、電力量計から電気自動車充電のための配線を分電盤を介さずに直接引き出すことを可能とした配線システムを提供することを目的としている。   In view of the above problems, an object of the present invention is to provide a wiring system that can directly draw a wiring for charging an electric vehicle from a watt hour meter without using a distribution board.

上記課題を解決する為に、請求項１の発明は、屋外に設置されて電力量計の二次側の幹線を引き込んだ中継ボックスと、幹線から分岐されて中継ボックスから引き出され、屋内の分電盤へ配設される屋内幹線と、同様に幹線から分岐されて中継ボックスから引き出され、電気自動車を充電するための充電器まで配設される分岐幹線とを備え、中継ボックスには、幹線が接続されて契約電流値を越える電流が幹線に流れたら遮断動作する主幹ブレーカと、分岐幹線の途中に配置された分岐ブレーカとが収容されて成ることを特徴とする。
この構成によれば、充電器への配線を電力量計から屋外に設置した中継ボックスを介するだけで敷設できるため、分電盤を介する必要が無く簡易な配線工事で済む。また、分電盤の分岐配線の追加等も必要なく、既存設備を変更せずに済む。 In order to solve the above-mentioned problems, the invention of claim 1 includes a relay box installed outdoors and drawn in a trunk line on the secondary side of a watt-hour meter, and a branch box branched from the trunk line and drawn out from the relay box. An indoor trunk line that is disposed on the electrical panel, and a branch trunk line that is also branched from the trunk line and pulled out of the relay box and is also provided with a charger for charging the electric vehicle. Are connected to each other, and a branch breaker disposed in the middle of the branch trunk is accommodated.
According to this configuration, since the wiring to the charger can be laid only from the watt hour meter via the relay box installed outdoors, it is not necessary to go through the distribution board, and simple wiring work is sufficient. Further, there is no need to add branch wiring of the distribution board, and existing facilities do not need to be changed.

請求項２の発明は、請求項１に記載の構成において、主幹ブレーカは、幹線に流れる電流が特定の電流値を越えたら制御信号を外部に出力する電流監視部を備えると共に、充電器は制御信号を受けて自身に供給される電流を制御する電流制御部を備えており、特定の電流値が、契約電流値より一定割合小さい電流値であって、制御信号を受けた電流制御部は、充電器に流れる分岐幹線の電流を削減又は停止させることを特徴とする。
この構成によれば、住戸全体の使用電流が契約電流値より低い特定の電流値を越えたら、電気自動車を充電する充電器へ流れる電流を削減或いは停止するため、家庭での使用電流を削減でき主幹ブレーカが遮断動作して停電となる事態を防止できる。また、幹線電流を削減しても分電盤側に変化は無いため、居住者への影響は最小限で済む。 According to a second aspect of the present invention, in the configuration of the first aspect, the main breaker includes a current monitoring unit that outputs a control signal to the outside when the current flowing through the main line exceeds a specific current value, and the charger is controlled. A current control unit that receives a signal and controls a current supplied to itself is provided, and the specific current value is a current value that is a certain percentage smaller than the contract current value. It is characterized in that the current of the branch main line flowing to the charger is reduced or stopped.
According to this configuration, if the current used by the entire dwelling unit exceeds a specific current value lower than the contracted current value, the current flowing to the charger for charging the electric vehicle is reduced or stopped, so that the current used at home can be reduced. It is possible to prevent the main breaker from shutting down and causing a power failure. Moreover, even if the main line current is reduced, there is no change on the distribution board side, so the influence on the occupants is minimal.

本発明によれば、充電器への配線を電力量計から屋外に設置した中継ボックスを介するだけで敷設できるため、分電盤を介する必要が無く簡易な配線工事で済む。また、分電盤の分岐配線の追加等も必要なく、既存設備を変更せずに済む。   According to the present invention, since the wiring to the charger can be laid only through the relay box installed outdoors from the watt hour meter, it is not necessary to go through the distribution board, and simple wiring work is sufficient. Further, there is no need to add branch wiring of the distribution board, and existing facilities do not need to be changed.

中継ボックス２には、主幹ブレーカ６と分岐ブレーカ７が収容されている。主幹ブレーカ６の一次側は電力量計１の二次側から送出された幹線Ｌ２が接続され、主幹ブレーカ６の２次側は分岐されて、分電盤４へ至る屋内幹線Ｌ３と、充電器３に至る分岐幹線Ｌ４の双方が接続されている。分岐ブレーカ７は分岐幹線Ｌ４の途中に配置されている。また、主幹ブレーカ６と充電器３との間には信号線Ｌ５が配設されている。
尚、分電盤４の構成は従来と同様であり、住戸Ｈ内に設置されて１つの主開閉器４１、複数の分岐ブレーカ４２が組み付けられている。但し、電流制限器としての機能は主幹ブレーカ６が有しており、主開閉器４１は漏電遮断機能を有している。 The relay box 2 accommodates a main breaker 6 and a branch breaker 7. The primary side of the main breaker 6 is connected to the main line L2 sent from the secondary side of the watt-hour meter 1, the secondary side of the main breaker 6 is branched, the indoor main line L3 leading to the distribution board 4, and the charger Both branch trunk lines L4 leading to 3 are connected. The branch breaker 7 is disposed in the middle of the branch main line L4. A signal line L5 is disposed between the main breaker 6 and the charger 3.
In addition, the structure of the distribution board 4 is the same as that of the past, and it is installed in the dwelling unit H, and one main switch 41 and a plurality of branch breakers 42 are assembled. However, the main circuit breaker 6 has a function as a current limiter, and the main switch 41 has a leakage breaker function.

図３は主幹ブレーカ６のブロック図であり、内部構成を示している。図３に示すように、開閉接点６１、開閉接点６１を開操作するトリップコイル６２及びその駆動回路６２ａ、幹線Ｌ２に流れる電流である電路電流を検出する電流センサ６３、主幹ブレーカ６を制御する主幹ブレーカ制御部６４、主幹ブレーカ制御部６４に電源を供給する電源回路６５等を備えている。また、６６は一次側接続端子、６７は二次側接続端子、６８は制御信号を出力する制御端子である。   FIG. 3 is a block diagram of the main breaker 6 and shows the internal configuration. As shown in FIG. 3, the switching contact 61, the trip coil 62 for opening / closing the switching contact 61 and its drive circuit 62a, the current sensor 63 for detecting the electric circuit current that flows through the trunk line L2, and the trunk for controlling the trunk breaker 6. A breaker control unit 64 and a power supply circuit 65 for supplying power to the main breaker control unit 64 are provided. Reference numeral 66 denotes a primary side connection terminal, 67 denotes a secondary side connection terminal, and 68 denotes a control terminal for outputting a control signal.

主幹ブレーカ制御部６４は、幹線Ｌ２の負荷側で発生する漏電を検知する漏電判定部６４ａ、契約電流値を越えていないか判断する過電流判定部６４ｂ、契約電流に対して一定割合で設定（例えば８０％に設定）された特定の電流値を越えていないか判断する電流監視部６４ｃ、契約電流値及び基準電流値等を記憶する記憶部６４ｄを備えている。尚、契約電流値（契約アンペア数）は、電力会社との契約に基づき施工時に設定され、特定の電流値は、契約電流値が設定されたらその一定割合で自動設定される。   The main breaker control unit 64 is set at a constant rate with respect to the contract current, the leakage determination unit 64a for detecting the leakage occurring on the load side of the trunk line L2, the overcurrent determination unit 64b for determining whether or not the contract current value is exceeded ( For example, a current monitoring unit 64c that determines whether or not a specific current value set to 80% is exceeded, and a storage unit 64d that stores a contract current value, a reference current value, and the like are provided. The contract current value (contract amperage) is set at the time of construction based on a contract with the electric power company, and the specific current value is automatically set at a certain ratio when the contract current value is set.

図４は充電器３のブロック図を示している。３１は整流回路や電流制御回路を備えた充電回路、３２は充電回路３１を制御して電流のオン／オフ、或いは分岐幹線Ｌ４を流れる充電電流値をコントロールする制御回路、３３は電気自動車Ｖが接続されるコネクタである。   FIG. 4 shows a block diagram of the charger 3. 31 is a charging circuit including a rectifier circuit and a current control circuit, 32 is a control circuit that controls the charging circuit 31 to control on / off of the current or a charging current value flowing through the branch trunk L4, and 33 is an electric vehicle V. It is a connector to be connected.

上記のように配線システムが構成されることで、主幹ブレーカ６は次のように動作する。先ず主幹ブレーカ６は、電流制限器としての機能を有しており、契約電流を越える電流が幹線Ｌ２に流れたら、遮断動作する。具体的に、記憶部６４ｄに記憶されている契約電流に基づいて、電流センサ６３が検出した電路電流が、契約電流を越えたと過電流判定部６４ｂが判断したら、駆動回路６２ａを介してトリップコイル６２をトリップさせて開閉接点６１を開操作する。こうして幹線Ｌ２は遮断される。
また、屋内幹線Ｌ３或いは分岐幹線Ｌ４で漏電が発生したら漏電判定部６４ａがそれを検知して、過電流が流れた場合と同様に開閉接点６１が開動作する。 By configuring the wiring system as described above, the main breaker 6 operates as follows. First, the main breaker 6 has a function as a current limiter. When a current exceeding the contract current flows through the main line L2, the main breaker 6 performs a cut-off operation. Specifically, when the overcurrent determination unit 64b determines that the circuit current detected by the current sensor 63 exceeds the contract current based on the contract current stored in the storage unit 64d, the trip coil is connected via the drive circuit 62a. 62 is tripped to open the switching contact 61. Thus, the trunk line L2 is blocked.
In addition, when a leakage occurs in the indoor trunk line L3 or the branch trunk line L4, the leakage determination unit 64a detects this, and the open / close contact 61 opens as in the case where an overcurrent flows.

加えて以下の制御を実施する。電気自動車Ｖへの充電が開始されたことで住戸全体での使用電流が増加し、幹線Ｌ２に流れる電流が契約電流値には達しないが特定の電流値を越えたら、所定の制御信号が制御端子６８から出力される。
具体的に、記憶部６４ｄには電流監視部６４ｃが判定の基準とする特定の電流値が記憶されており、幹線Ｌ２の電流値がこの特定の電流値を越えたら、電流監視部６４ｃから制御端子６８を介して所定の制御信号（例えば充電電流を２分の１に下げる信号）が出力される。 In addition, the following control is performed. When the charging to the electric vehicle V is started, the current used in the entire dwelling unit increases, and the current flowing through the trunk line L2 does not reach the contract current value but exceeds a specific current value, a predetermined control signal is controlled. Output from terminal 68.
Specifically, the storage unit 64d stores a specific current value used as a reference for determination by the current monitoring unit 64c. When the current value of the trunk line L2 exceeds the specific current value, the current monitoring unit 64c controls the current value. A predetermined control signal (for example, a signal for reducing the charging current by half) is output via the terminal 68.

この信号は、信号線Ｌ５を介して充電器３に伝送され、充電器３では制御回路３２がそれを受信し、充電回路３１を制御して充電電流を削減させる。このとき、分岐幹線Ｌ４に流れる電流が、例えば３０アンペアから１５アンペアと半減するよう制御される。   This signal is transmitted to the charger 3 via the signal line L5. In the charger 3, the control circuit 32 receives it and controls the charging circuit 31 to reduce the charging current. At this time, the current flowing through the branch trunk line L4 is controlled to be halved, for example, from 30 amperes to 15 amperes.

このように、充電器３への配線を電力量計から屋外に設置した中継ボックス２を介するだけで敷設できるため、分電盤４を介する必要が無く簡易な配線工事で済む。また、分電盤４の分岐配線の追加等も必要なく、既存設備を変更せずに済む。
また、住戸Ｈ全体の使用電流が契約電流値より低い特定の電流値を越えたら、電気自動車Ｖを充電する充電器３へ流れる電流を削減するため、家庭での使用電流を削減でき主幹ブレーカ６が遮断動作して停電となる事態を防止できる。また、幹線Ｌ２の電流を削減しても分電盤４側に変化は無いため、居住者への影響は最小限で済む。 As described above, since the wiring to the charger 3 can be laid only from the watt hour meter through the relay box 2 installed outdoors, there is no need to go through the distribution board 4 and simple wiring work is sufficient. In addition, it is not necessary to add branch wiring of the distribution board 4 and the existing equipment is not changed.
In addition, if the current used by the entire dwelling unit H exceeds a specific current value lower than the contracted current value, the current that flows to the charger 3 that charges the electric vehicle V can be reduced. Can be prevented from shutting down and causing a power outage. Moreover, even if the current of the trunk line L2 is reduced, there is no change on the distribution board 4 side, so the influence on the occupants can be minimized.

尚、上記実施形態では、分岐幹線Ｌ４に流れる電流を半減させる制御を行っているが、削減する割合は任意であるし、分岐幹線Ｌ４に流れる電流をゼロにする制御を実施しても良い。   In the above-described embodiment, control is performed to reduce the current flowing through the branch trunk line L4 by half. However, the reduction ratio is arbitrary, and control to make the current flowing through the branch trunk line L4 zero is also possible.
