以下に本発明の好ましい実施形態を示す。   Preferred embodiments of the present invention are shown below.

図1に示すように、本実施形態の電気自動車用充電装置1は、基台2上に、高圧受変電設備3と、高圧受変電設備3で低圧変換された電力を電気自動車へ供給する給電設備4を隣接配置して構成されている。   As shown in FIG. 1, the charging device 1 for an electric vehicle according to the present embodiment has a high voltage receiving / transforming equipment 3 on a base 2 and an electric power supply for supplying electric power converted into a low voltage by the high voltage receiving / transforming equipment 3 to the electric vehicle. The equipment 4 is arranged adjacent to each other.

高圧受変電設備3は、変電所から供給される高い電圧の電力を、需要家で使用できる低い電圧に変圧する設備であり、各種の保護装置や計測装置、配電装置を内蔵している。   The high-voltage receiving / transforming equipment 3 is equipment that transforms high-voltage power supplied from a substation into a low voltage that can be used by consumers, and incorporates various protection devices, measuring devices, and power distribution devices.

給電設備4は、高圧受変電設備3に内蔵された変圧器の容量に応じて、急速充電用あるいは普通充電用から適宜選択して使用することができる。   The power feeding facility 4 can be used by appropriately selecting from quick charging or normal charging according to the capacity of the transformer built in the high voltage receiving / transforming facility 3.

本実施形態の基台2は、鉄製の枠体を一体に形成したものである。その他の実施形態として、板金板を溶接して枠状に形成したものとすることもできる。   The base 2 of the present embodiment is formed by integrally forming an iron frame. As another embodiment, a sheet metal plate may be welded and formed into a frame shape.

図2に示すように、基台2は、表面に、高圧受変電設備3と給電設備4を設置する際の使用される取付孔5が複数形成されている。   As shown in FIG. 2, the base 2 has a plurality of mounting holes 5 formed on the surface for use when installing the high voltage receiving / transforming equipment 3 and the power feeding equipment 4.

図3に示すように、基台2内部の中央部には、高圧受変電設備3および給電設備4への配線を収納する配線収納部6が形成されている。   As shown in FIG. 3, a wiring storage portion 6 that stores wiring to the high-voltage receiving / transforming equipment 3 and the power feeding equipment 4 is formed in the center of the base 2.

電気自動車用充電装置1を設置現場に搬送する前に、予め、高圧受変電設備3と給電設備4の配線を済ませて、配線を配線収納部6に収納した状態として、設置現場に搬送することにより、従来、電気自動車用充電装置の導入に際し、設置現場で従来必要となっていた各種作業(基礎工事や掘削作業、更には、受電系統と給電系統間の配線作業)を省略して、高圧受変電設備への入線作業と接地作業にのみとすることができ、電気自動車用充電装置の導入作業を簡易化することができる。   Before the electric vehicle charging device 1 is transported to the installation site, the wiring of the high-voltage receiving / transforming equipment 3 and the power feeding equipment 4 is completed in advance, and the wiring is stored in the wiring storage unit 6 and transported to the installation site. As a result, it is possible to eliminate the various work (foundation work, excavation work, and wiring work between the power receiving system and the power feeding system) conventionally required at the installation site when introducing the charging device for an electric vehicle. It is possible to perform only the work for entering and grounding the power receiving / transforming equipment, and the work for introducing the charging device for the electric vehicle can be simplified.

電気自動車用充電装置1の搬送は、図3に示すように、基台2内部の左右に形成された搬送用孔部7にフォークリフトの腕部を貫通させて行うことができる。   As shown in FIG. 3, the electric vehicle charging device 1 can be transported by passing the arm portion of the forklift through the transport holes 7 formed on the left and right inside the base 2.

フォークリフトを用いて電気自動車用充電装置1の搬送を行う際、フォークリフトの腕部に配線が絡まる事故を回避するために、配線収納部6と搬送用孔部7が重複しないよう区画することが望ましい。図3に示す実施形態では、配線収納部6を完全に囲うように凹状の区画部材8を配置している。その他の実施形態として、図4に示すように、配線収納部6と搬送用孔部7を仕切る仕切板9を配置することもできる。   When the electric vehicle charging device 1 is transported using a forklift, it is desirable to partition the wiring housing 6 and the transport hole 7 so as not to overlap each other in order to avoid an accident in which the wiring is entangled with the arm of the forklift. . In the embodiment shown in FIG. 3, the concave partitioning member 8 is disposed so as to completely surround the wiring housing portion 6. As another embodiment, as shown in FIG. 4, a partition plate 9 that partitions the wiring storage portion 6 and the transfer hole portion 7 may be disposed.

搬送用孔部7は、不使用時にブランクパネルなどの覆い板でカバーできる構造としておくことで、良好な景観を確保することができる。   The transport hole 7 can ensure a good landscape by providing a structure that can be covered with a cover plate such as a blank panel when not in use.

図5および図6に示すように、基台2の側面には、窪み部10が形成されている。窪み部10には、基台2を地面にアンカーボルト14で固定する際に使用されるアンカー接続孔11が形成されている。このように、アンカー接続孔11を窪み部10に設けることにより、基台2の固定に使用されるアンカーボルトに躓く事故を回避することができる。   As shown in FIGS. 5 and 6, a recess 10 is formed on the side surface of the base 2. An anchor connection hole 11 that is used when the base 2 is fixed to the ground with anchor bolts 14 is formed in the recess 10. As described above, by providing the anchor connection hole 11 in the recess 10, it is possible to avoid an accident incurring the anchor bolt used for fixing the base 2.

なお、送電線から高圧受変電設備3への電力の引き込みは、地中から行うことが好ましいが、窪み部10に引込ケーブル挿入用の挿入孔12を形成することもできる。この挿入孔12を利用して電力の引き込みを行う場合、電気自動車用充電装置の導入に際し、通常必要となる基礎工事や掘削作業を省略することができる。ただし、挿入孔12を利用して電力の引き込みを行う場合、引き込みケーブルの被覆が、挿入孔12との接触によって破損する事故を回避するため、図6に示すように、引き込みケーブル15をグロメット16などで補強するとともに、グロメット16が窪み部10から外部に突出しないように配置することが望ましい。   In addition, although it is preferable to draw in the electric power from the power transmission line to the high-voltage receiving / transforming equipment 3 from the ground, an insertion hole 12 for inserting the drawing-in cable can be formed in the recessed portion 10. When power is drawn using the insertion hole 12, foundation work and excavation work that are normally required when introducing the charging device for an electric vehicle can be omitted. However, when power is drawn in using the insertion hole 12, in order to avoid an accident in which the cover of the lead-in cable is damaged due to contact with the insertion hole 12, as shown in FIG. It is desirable to arrange the grommet 16 so that the grommet 16 does not protrude outside from the recess 10.

図2に示すように、基台2上面の4隅には、基台2を吊り上げる際に使用する吊上部13が形成されている。吊上部13は、基台2の中心を対称点として、対称配置することが好ましい。
基台2上に配置される高圧受変電設備3と給電設備4には、様々な形状や重さのものがあるが、吊上部13を、基台2の中心を対称点として、対称配置することにより、高圧受変電設備3と給電設備4の形状や重さに関わりなく、バランスよく吊り上げ作業を行うことができる。なお、吊上部13は、基台2と着脱自在な構成としてもよいし、基台2と一体に形成することもできる。
As shown in FIG. 2, suspension upper portions 13 used when lifting the base 2 are formed at the four corners of the upper surface of the base 2. The suspended portion 13 is preferably arranged symmetrically with the center of the base 2 as the symmetry point.
There are various shapes and weights of the high-voltage power receiving / transforming equipment 3 and the power feeding equipment 4 arranged on the base 2, but the suspended portion 13 is arranged symmetrically with the center of the base 2 as the symmetry point. Thus, the lifting work can be performed in a balanced manner regardless of the shape and weight of the high-voltage receiving / transforming equipment 3 and the power feeding equipment 4. The hanging portion 13 may be configured to be detachable from the base 2 or may be formed integrally with the base 2.

図1、図7、図8に示すように、高圧受変電設備3と給電設備4の配置に際し、扉の方向は適宜自在に選択することができる。例えば、図1や図7の実施形態では、高圧受変電設備3と給電設備4を、各々の背面板が向き合うように、背中合わせとし、給電設備4の扉4aが、充電作業者に対して正面に向くように配置している。   As shown in FIGS. 1, 7, and 8, when the high-voltage receiving / transforming equipment 3 and the power feeding equipment 4 are arranged, the direction of the door can be appropriately selected. For example, in the embodiment shown in FIGS. 1 and 7, the high-voltage power receiving / transforming equipment 3 and the power feeding equipment 4 are back to back so that the back plates face each other, and the door 4a of the power feeding equipment 4 is in front of the charging operator. It is arranged to face.

また、図7に示すように、基台2上に隣接配置された高圧受変電設備3と給電設備4のうち、駐車場スペース17には給電設備4のみを配置して、駐車スペースを広く確保するとともに、高圧受変電設備3は管理者専用区域19に配置して、高圧受変電設備3への部外者のアクセスを禁止することもできる。   Further, as shown in FIG. 7, among the high-voltage receiving and transforming equipment 3 and the power feeding equipment 4 that are arranged adjacent to each other on the base 2, only the power feeding equipment 4 is arranged in the parking lot space 17 to secure a wide parking space. At the same time, the high-voltage receiving / transforming equipment 3 can be arranged in the manager-exclusive area 19 to prohibit outsiders from accessing the high-voltage receiving / transforming equipment 3.

また、図8に示すように、本発明の電気自動車用充電装置1に、更に、給電設備15を増設することで、駐車場スペースで複数台の電気自動車18への同時充電を行うこともできる。この場合、給電設備15への電力供給は、電気自動車用充電装置1の高圧受変電設備3からの引き込みにより行われる。引き込みは地面からあるいは基台側面から引き出す方法を適宜選択して行うことができる。   Moreover, as shown in FIG. 8, the electric vehicle charging apparatus 1 according to the present invention can be additionally charged with a plurality of electric vehicles 18 in a parking space by further adding a power supply facility 15. . In this case, the power supply to the power supply facility 15 is performed by pulling in the electric vehicle charging apparatus 1 from the high-voltage receiving / transforming facility 3. The pull-in can be performed by appropriately selecting a method of pulling out from the ground or from the side of the base.

前記のように、給電設備4は、高圧受変電設備3に内蔵された変圧器の容量に応じて、急速受電用あるいは普通充電用から適宜選択して使用することができるが、図9に示すように、同一の基台2上に、急速受電用と普通充電用の2つの給電設備4を配置することもできる。その他、基台2上に電灯や看板を設置したり、電灯や看板などへの電源の供給を行う電源盤21などを設置することもできる。勿論、電灯や看板、電源盤21なども予め配線しておくことにより現地での配線作業を簡略化させることが可能である。   As described above, the power supply facility 4 can be selected and used as appropriate for rapid power reception or normal charging according to the capacity of the transformer built in the high-voltage power receiving / transforming facility 3, as shown in FIG. As described above, two power feeding facilities 4 for rapid power reception and normal charging can be arranged on the same base 2. In addition, an electric lamp or a signboard can be installed on the base 2, or a power supply panel 21 for supplying power to the electric lamp or the signboard can be installed. Of course, it is possible to simplify the wiring work in the field by wiring the lamp, the signboard, the power supply panel 21 and the like in advance.

給電設備4や高圧受変電設備3内に収納される機器はユニット化しておくことが好ましい。例えば、給電設備4内に収めきれなくなった機器ユニット(サーバーなど)を、高圧受変電設備3の筐体の空きスペースに収納したり、図10に示すように、変圧器などの変圧設備20と、高圧受変電設備3の筐体の空きスペースに、蓄電池などの蓄電設備16を収納することもできる。蓄電設備16への配線も、配線収納部6に纏めて収納することができる。高圧受変電設備3内に蓄電設備16を備えることにより、深夜など電気自動車に給電を行わない時間帯には蓄電設備16への蓄電を行い、蓄電された電力を、昼間の電力使用が増大する時間帯の給電に使用することができる。   The devices housed in the power supply facility 4 and the high-voltage receiving / transforming facility 3 are preferably unitized. For example, a device unit (such as a server) that can no longer be accommodated in the power supply facility 4 is stored in an empty space of the housing of the high-voltage receiving / transforming facility 3, or as shown in FIG. The storage facility 16 such as a storage battery can be accommodated in the empty space of the casing of the high-voltage receiving and transforming facility 3. Wiring to the power storage facility 16 can also be stored together in the wiring storage unit 6. By providing the power storage facility 16 in the high-voltage receiving and transforming facility 3, power storage to the power storage facility 16 is performed during a time period when power is not supplied to the electric vehicle, such as at midnight, and the use of the stored power in the daytime is increased. It can be used for time zone power feeding.
