【発明の属する技術分野】 BACKGROUND OF THE INVENTION
本発明は、一般住宅等宅内に設置されている電力線を利用した電力線通信において、単相三線式電力線通信を実現し、かつ、設置が簡便で安全である、異相線間カプラー及びその装着方法に関するものである。 The present invention, in the power line communication using a power line installed in a residential such premises, to achieve the single-phase three-wire power line communication, and installation is simple and safe, to couplers and their method of attachment between different phase lines it is intended.

【従来の技術】 BACKGROUND OF THE INVENTION
宅内電力線通信は、宅内の電気コンセントにモデム等を接続して、宅内に敷設されている電力線を伝送路として、宅内での情報通信を行うものである。 Home power line communication, connect the modem to the electrical outlet of the in-home, as a transmission path of power lines are laid to the home, and performs communication of information home. 既設の電力線と電気コンセントをそのまま利用して、例えば、コンピュータ及びその周辺装置、あるいは、家電製品を結ぶホームネットワークの構築と家庭内情報化を容易に実現できることから、近年注目を集めている。 By directly using an existing power line and the electrical outlet, for example, a computer and its peripheral devices, or from the home network of the building and home information of connecting the home appliances can be easily realized, it has attracted attention in recent years.
【0003】 [0003]
わが国の現行制度では、電力線通信に使用できる周波数帯は、10kHz〜450kHzと定められており、低速のデータ通信(9.6kbps程度)に利用されている。 In our current system, the frequency band that can be used for power line communication is established with 10KHz~450kHz, are utilized in the low-speed data communication (about 9.6 kbps). しかし、今後より高速のデータ通信(数10Mbps)が実現できるように、電力線通信に使用できる周波数帯に、2MHz〜30MHzの周波数帯を新たに追加する検討が行われている。 However, as can be realized from the high-speed data communication (number 10Mbps) the future, the frequency band that can be used for power line communication, consider adding a new frequency band of 2MHz~30MHz is being performed.
【0004】 [0004]
図9は、従来の宅内単相三線式電力線通信システムの配線図である。 Figure 9 is a wiring diagram of a conventional home single-phase three-wire power line communication system. 100V及び200Vの電力は、柱上トランス91から三本の電力線、即ち、第一の相の電力線U、中性線N、及び第二の相の電力線Wを用いて、宅内に配電される。 Power of 100V and 200V are three power lines from pole transformer 91, i.e., the power line U of the first phase, with a neutral line N, and the power line W of the second phase, which is distributed to the home. 100V系は、宅内では、分電盤内の主幹ブレーカ92を経て、電力線Uと中性線Nを対とした第一の配電系統と、電力線Wと中性線Nを対とした第二の配電系統とに分かれて、それぞれ配電される。 100V system, the home, through the main breaker 92 in the distribution board, the first distribution system to a pair of power lines U and neutral N, a second that a pair of power line W and the neutral line N divided into a power distribution system, are respectively the distribution.
【0005】 [0005]
第一の配電系統に接続された、モデム93とモデム94は、同一の回路内にあるため、相互の通信を容易に行える。 The first is connected to the power distribution system, the modem 93 and modem 94, because of the same in the circuit, enabling communication between them easily. 即ち、モデム93から送信するデータは、差動信号として第一の相の電力線Uと中性線Nに入力される。 That is, the data to be transmitted from the modem 93 is input as a differential signal to a first phase of the power line U and neutral N. この差動信号は、同じ配電系統にあるモデム94で、容易に、かつ良好に受信される。 The differential signal is a modem 94 in the same power distribution system, it is easily and favorably received. これが、同相における電力線通信である。 This is a power line communication in-phase.
【0006】 [0006]
しかし、第一の配電系統に接続された、モデム93あるいはモデム94と、第二の配電系統に接続された、モデム95との間の電力線通信は、異相線間電力線通信と呼ばれ、通常の状態では良好な通信を行うことが出来ない。 However, it is connected to the first distribution system, a modem 93 or modem 94, connected to the second distribution system, power line communication between the modem 95 is called a power line communication between different phase lines, normal You can not do a good communication in the state.
【0007】 [0007]
単相三線式配電では、中性線Nは共通であるが、第一の相の電力線Uと第二の相の電力線Wとは、異相関係にあり、これらは、柱上トランス91のおいて、接続されているに過ぎない。 The single-phase three-wire distribution, although the neutral line N is common, and the power line U of the first phase power line W of the second phase is in the heterophasic relationship, it is Oite the pole transformer 91 , not only it is connected. したがって、電力線通信に使用する数10kHz以上の周波数帯においては、第一の配電系統と第二の配電系統とは、それぞれ独立した別回路として動作する。 Therefore, in the number 10kHz or more frequency bands to be used for power line communication, the first distribution system and the second power distribution system, which operates as a separate circuits independently. 即ち、モデム93あるいはモデム94から、第一の配電系統に入力された差動信号は、第二の配電系統に接続されたモデム95の受信点では、著しく減衰しており、モデム95は、良好な信号検出が出来ない。 That is, modem 93 or modem 94, the differential signal inputted to the first distribution system, the reception point of the second modem 95 connected to the distribution system, are significantly attenuated, modem 95, good It can not be a signal detection.
【0008】 [0008]
このため、単相三線式電力通信では、異相線間の通信を実現するためには特別の仕組みが必要である。 Therefore, in the single-phase three-wire power communication requires special mechanisms in order to realize communication between different phase lines.
【0009】 [0009]
これを解決するため、図9に示されるように、コンデンサー96あるいはハイパスフィルタ(図示せず)を用いた異相線間カプラーを、主幹ブレーカ92の内部、あるいはその近傍に設置して、異相線間を高周波的に接続する方式が提案されている(特許文献1参照)。 To solve this, as shown in FIG. 9, a different phase lines between couplers with condenser 96 or the high-pass filter (not shown), installed inside the main breaker 92, or in the vicinity thereof between different phase lines method for high-frequency connected has been proposed (see Patent Document 1).
【0010】 [0010]
しかしながら、このようなコンデンサーやハイパスフィルタを既設の分電盤内部に取り付けるには、高電圧回路の工事となるため、電気主任技術者あるいは電気工事士による工事が必要となり、これらの資格を持たない一般人は、このような取り付けを禁じられている。 However, to install such a capacitor or high-pass filter within the existing distribution board, since the construction of the high voltage circuit, work by electric chief engineer or electrical worker is required, it does not have these qualifications the general public is forbidden such attachment.
