従来より商用電力は、昼間料金が高く夜間料金が低くなっている。そこで、負 荷を昼間から夜間にシフトして、商用電力の平滑化を図るとともに利用者側に電 力単価の安い夜間電力を昼間に利用できることが望まれていたが、それを可能に する装置は存在しなかった。 Conventionally, commercial power has high daytime charges and low nighttime charges. Therefore, it has been desired that the load be shifted from daytime to nighttime to smooth the commercial power and at the same time the user can use the nighttime power with a low power unit price in the daytime. Did not exist.

つぎに、図面に基づき本考案の一実施形態に係る電源装置を説明する。 図１に示すように、本実施形態の電力分散化電源装置は、充電器１と、蓄電池 ２と、インバータ３と、出力ターミナル４とを備えている。また、前記蓄電池２ への接続を前記充電器１と前記インバータ３との間で切換える第１スイッチＳＷ １と、前記出力ターミナル４への接続を前記インバータ３と交流商用電源Ｓとの 間で切換える第２スイッチＳＷ２と、前記充電器１の入力側を交流商用電源Ｓに 対し接続・切断する第３スイッチＳＷ３とを備えている。そして、各スイッチＳ Ｗ１、ＳＷ２、ＳＷ３を切換えるためのタイマーを内蔵した切換制御装置５が設 けられている。なお、６は交流商用電源Ｓを出力ターミナル４を接続するバイパ ス回路である。 Next, a power supply device according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the power decentralized power supply device of the present embodiment includes a charger 1, a storage battery 2, an inverter 3, and an output terminal 4. Also, the first switch SW 1 for switching the connection to the storage battery 2 between the charger 1 and the inverter 3, and the connection to the output terminal 4 between the inverter 3 and the AC commercial power supply S. A second switch SW2 and a third switch SW3 for connecting / disconnecting the input side of the charger 1 to / from the AC commercial power source S are provided. A switching control device 5 having a built-in timer for switching the switches SW1, SW2, and SW3 is provided. Reference numeral 6 is a bypass circuit for connecting the AC commercial power source S to the output terminal 4.
【０００６】 つぎに、本実施形態の電源装置の利用方法を図２〜３に基づき説明する。 夜間動作時は第１スイッチＳＷ１を充電器側に、第３スイッチＳＷ３を電源Ｓ 側に接続する。この場合、図２に示すように、商用電源Ｓより電力の供給を受け 充電器１を経由して交流電力から直流電力に順変換した後、蓄電池２に直流電力 として充電する。夜間使用する負荷設備については、第２スイッチＳＷ２をバイ パス回路６側に接続しておき、バイパス回路６を経由して商用電源から直接交流 電力を供給する。Next, a method of using the power supply device of this embodiment will be described with reference to FIGS. During nighttime operation, the first switch SW1 is connected to the charger side and the third switch SW3 is connected to the power source S side. In this case, as shown in FIG. 2, electric power is supplied from the commercial power source S, the AC power is converted to DC power through the charger 1, and then the storage battery 2 is charged as DC power. For load equipment used at night, the second switch SW2 is connected to the bypass circuit 6 side, and AC power is directly supplied from the commercial power source via the bypass circuit 6.
【０００７】 昼間動作時は、第１スイッチＳＷ１をインバータ３側に、第２スイッチＳＷ２ をインバータ３側に接続する。この場合、図３に示すように、夜間使用していた バイパス回路を切り離し、商用電源からの電力供給を停止し、蓄電池２内の直流 電力をインバータ３を経由して直流電力から交流電力に逆変換して、負荷設備に 商用電力と同一の特性を持つ交流電力として供給する。昼間使用中、蓄電池２内 の直流電力がなくなった場合は、第２スイッチＳＷ２をバイパス回路６側に切り 替え、商用電源から直接交流電力を負荷設備に供給する。During the daytime operation, the first switch SW1 is connected to the inverter 3 side and the second switch SW2 is connected to the inverter 3 side. In this case, as shown in Fig. 3, the bypass circuit used at night is disconnected, the power supply from the commercial power supply is stopped, and the DC power in the storage battery 2 is switched from the DC power to the AC power via the inverter 3. It is converted and supplied to the load equipment as AC power with the same characteristics as commercial power. When the DC power in the storage battery 2 runs out during daytime use, the second switch SW2 is switched to the bypass circuit 6 side, and AC power is directly supplied to the load equipment from the commercial power supply.
【０００８】 要するに、本考案では、夜間期間は、商用電源Ｓより電力の供給を受けて、充 電器１を経由して、交流電力から直流電力に変換したのち、蓄電池２に直流電力 として保存する。それとともに、夜間期間に使用する２次側電気負荷設備には、 バイパス回路を経由して商用電源から、交流電力をそのまま供給する。一方、昼 間期間には、夜間使用していたバイパス回路を切断して、商用電源Ｓからの電力 供給を停止し、直流電力として蓄積している蓄電池２内の電力をインバータ３を 用いて直流電力から交流電力に変換して、２次側電気負荷設備に商用電力と同一 の特性を持つ交流電力を供給するのである。In short, in the present invention, during the nighttime period, power is supplied from the commercial power source S, converted from AC power to DC power via the charger 1, and then stored in the storage battery 2 as DC power. . At the same time, AC power is supplied as is from the commercial power supply to the secondary-side electric load equipment used during the nighttime through a bypass circuit. On the other hand, during the daytime, the bypass circuit used at night is cut off, the power supply from the commercial power source S is stopped, and the power in the storage battery 2 accumulated as DC power is converted to DC power using the inverter 3. The power is converted to AC power, and AC power with the same characteristics as commercial power is supplied to the secondary-side electric load equipment.
【０００９】 本考案は、家庭用あるいは事業用（商店やオフィスビル）に利用価値が高い。The present invention has high utility value for home use or business use (shops and office buildings).
