本発明は、電機器を有した盤筐体を、設置面に設置する盤設置システムに関する。 The present invention relates to a panel installation system for installing a panel housing having electrical equipment on an installation surface.
従来、変電設備ユニットが知られている（特許文献１参照）。
この変電設備ユニットは、複数の直流電源のそれぞれに対応して設けられ、前記直流電源から入力される直流電力を三相交流電力に変換する複数の電力変換部と、前記複数の電力変換部を収容する筐体と、前記複数の電力変換部のそれぞれの出力が合成されて出力された三相交流電力を入力して当該入力した三相交流電力の電圧値を電力系統の電圧値に昇圧する昇圧用変圧器と、前記昇圧用変圧器と電力系統との間に設けられ、前記昇圧用変圧器と電力系統との間の電力伝送路を遮断する機能を有する系統連系盤と、を備え、前記複数の電力変換部と前記昇圧用変圧器との間の交流電力の伝送路は、前記筐体と前記昇圧用変圧器との間に設置されたダクト内を通ると共に、当該ダクトに対して絶縁破壊が生じない一定以上の距離を離間して配置されるように当該ダクト内の取り付け位置が定まっている。
Conventionally, a substation facility unit is known (see Patent Literature 1).
The substation equipment unit is provided for each of a plurality of DC power supplies, a plurality of power conversion units that convert DC power input from the DC power supply into three-phase AC power, and the plurality of power conversion units The three-phase AC power output by combining the outputs of the housing and the plurality of power converters is input, and the voltage value of the input three-phase AC power is boosted to the voltage value of the power system. A step-up transformer, and a system interconnection board provided between the step-up transformer and the power system, the system interconnection panel having a function of cutting off a power transmission path between the step-up transformer and the power system. The transmission path of AC power between the plurality of power conversion units and the step-up transformer passes through a duct installed between the housing and the step-up transformer, and with respect to the duct. Separated by a distance equal to or greater than Mounting position in the duct is definite to be.
しかしながら、特許文献１に記載された変電設備ユニットは、その段落００３２、００５４、００５６に記載されたように、当該変電設備ユニットにおける電力変換装置、昇圧用変圧器及び系統連系盤を、共通のコンクリート製の基礎の上に直接配置しているため、そのコンクリート製の基礎の上面全体を削る等をしてレベルを出す（上面全体を略水平にする）こととなり、配置する変電設備ユニットを略水平にし難く、その結果、基礎上に設置した変電設備ユニットの各筐体が歪み、扉が空かない、閉まらない等の問題がある。 However, as described in the paragraphs 0032, 0054, 0056, the substation equipment unit described in Patent Document 1 shares the power converter, the boosting transformer, and the system interconnection board in the substation equipment unit. Since it is placed directly on a concrete foundation, the entire upper surface of the concrete foundation is cut down to raise the level (the entire upper surface is made substantially horizontal). It is difficult to make it horizontal, and as a result, there is a problem that each housing of the substation equipment unit installed on the foundation is distorted and the door is not vacant or closed.
この他、従来の配電盤は、特許文献２の第１図〜第４図のように、設置場所の床面７に置かれるチャンネルベース５と、このチャンネルベース５上に置かれる配電盤ケース１とを有し、この配電盤ケース１は、チャンネルベース５上に取り付けられる配電盤底部２を有している。
しかしながら、特許文献２に開示された配電盤は、チャンネルベース５上に、配電盤ケース１の配電盤底部２の全体を載せるため、本来不要なチャンネルベース５又は配電盤底部２の高さ分だけ高くなる問題点がある。
又、設置した配電盤の高さが高くなることで、設置場所が制限される他、チャンネルベース５又は配電盤底部２の重さの分だけ、配電盤そのものや、チャンネルベース５の運搬が困難となる。
In addition, as shown in FIGS. 1 to 4 of Patent Document 2, a conventional switchboard includes a channel base 5 placed on a floor 7 at an installation location and a switchboard case 1 placed on the channel base 5. The switchboard case 1 has a switchboard bottom 2 mounted on a channel base 5.
However, in the switchboard disclosed in Patent Literature 2, since the entire switchboard bottom 2 of the switchboard case 1 is mounted on the channel base 5, the switchboard is unnecessarily high by the height of the channel base 5 or the switchboard bottom 2. There is.
In addition, since the height of the installed switchboard is increased, the installation place is limited, and the transport of the switchboard itself or the channel base 5 becomes difficult by the weight of the channel base 5 or the switchboard bottom 2.
本発明は、このような点に鑑み、盤筐体側の盤部材と設置面側の土台部材を水平方向視で重ねることによって、「レベル出しの容易化」や「設置高さの低減」、「運搬負担の軽減」を図れる盤設置システムを提供することを目的とする。 In view of such a point, the present invention superimposes the board member on the board housing side and the base member on the installation surface side in a horizontal direction, thereby facilitating “leveling out” and “reducing the installation height”, “ The purpose of the present invention is to provide a board installation system that can reduce the burden of transportation.
本発明に係る盤設置システム１０は、電機器Ｄを有した盤筐体１２を、設置面Ｓに設置する盤設置システムであって、前記盤筐体１２側に設けられた盤部材１３が、前記設置面Ｓ側に設けられ且つ前記盤筐体１２を下方から支持する土台部材１４と、水平方向視で、重なる部分を有していることを第１の特徴とする。
尚、本発明における「電機器Ｄ」とは、例えば、盤筐体１２外からの交流電流等を集電する集電部や、交流電流をより高圧な交流電流に変圧する変圧器、交流電流を盤筐体１２外へ送電する送電部、直流電流を交流電流に変換するパワーコンディショナなどのうち、少なくとも１つであっても良く、その他、遮断機（ブレーカ）や、逆流防止ダイオード、開閉器、エアコン、無停電電源装置（ＵＰＳ）、補機、ヒューズ、リレー（継電器）、ケーブル（配線コード）、端子、コネクタ、センサ（電流計、電圧計）、ＣＰＵ、蓄電池、制御部など、電気・電力を使って作動する何れの機器であっても構わない。
The board installation system 10 according to the present invention is a board installation system that installs a panel housing 12 having an electric device D on an installation surface S, and a panel member 13 provided on the panel housing 12 side includes: A first feature is that a base member 14 provided on the installation surface S side and supporting the board housing 12 from below has an overlapping portion when viewed in a horizontal direction.
The “electric device D” in the present invention includes, for example, a current collecting unit that collects AC current and the like from outside the panel housing 12, a transformer that transforms AC current into a higher AC current, an AC current At least one of a power transmission unit for transmitting power to the outside of the panel housing 12, a power conditioner for converting DC current to AC current, and the like. In addition, a circuit breaker, a backflow prevention diode, , Air conditioner, uninterruptible power supply (UPS), auxiliary equipment, fuse, relay (relay), cable (wiring cord), terminal, connector, sensor (ammeter, voltmeter), CPU, storage battery, control unit -Any device that operates using electric power may be used.
本発明に係る盤設置システム１０の第２の特徴は、上記第１の特徴に加えて、前記土台部材１４では、金属製の部材のみが用いられている点にある。 A second feature of the board installation system 10 according to the present invention is that, in addition to the first feature, the base member 14 uses only a metal member.
本発明に係る盤設置システム１０の第３の特徴は、上記第１又は２の特徴に加えて、前記土台部材１４は、前記設置面Ｓに打ち込まれた金属製の杭部材１５の上に、金属製の棒状部材１６を配設して構成されている点にある。 A third feature of the board installation system 10 according to the present invention is that, in addition to the first or second feature, the base member 14 is provided on a metal pile member 15 driven into the installation surface S, The point is that it is configured by disposing a metal rod-shaped member 16.
本発明に係る盤設置システム１０の第４の特徴は、上記第３の特徴に加えて、前記土台部材１４は、前記棒状部材１６を前記盤筐体１２における所定一方向に略沿ってのみ配設して構成されている点にある。
尚、本発明における「盤筐体１２における所定一方向」とは、盤筐体１２における左右方向や、前後方向、上下方向、斜め方向などのうち、何れか一方向である。
A fourth feature of the board installation system 10 according to the present invention is that, in addition to the third feature, the base member 14 disposes the bar-shaped member 16 substantially only along one predetermined direction in the board casing 12. The point is that it is configured.
The “predetermined one direction in the panel housing 12” in the present invention is any one of the left-right direction, the front-rear direction, the vertical direction, the oblique direction, and the like in the panel housing 12.
これらの特徴により、盤筐体１２側に設けられた盤部材１３を、設置面Ｓ側に設けられ且つ盤筐体１２を下方から支持する土台部材１４と、水平方向視で重ねることによって、特許文献１とは異なり、盤部材１３及び土台部材１４を介して、盤筐体１２を設置面Ｓに設置するため、設置面Ｓ側の土台部材１４をレベル調整しておくだけで、当該土台部材１４上の盤筐体１２が容易に略水平となり（「レベル出しの容易化」）、その結果、筐体の歪みや、扉が空かない、閉まらない等の問題も抑制できる。
これは、先に設けた土台部材１４側で設置前にレベルを出しておき、後は盤筐体１２やその盤部材１３を載せるだけとなるため、設置容易化が図れるとも言える。
これと同時に、特許文献２とは異なり、盤部材１３と土台部材１４の水平方向視で重なった分だけ、盤筐体１２を設置した後の高さを低くすることが可能となる（「設置高さの低減」）と共に、運搬せず予め設置面Ｓに配設する土台部材１４の分だけ運搬時の重さが減り、負担を軽減できる（「運搬負担の軽減」）。
By these features, the panel member 13 provided on the panel housing 12 side is overlapped with the base member 14 provided on the installation surface S side and supporting the panel housing 12 from below in a horizontal direction, so that the patent is provided. Unlike the document 1, the board member 12 is installed on the installation surface S via the board member 13 and the base member 14. Therefore, the level of the base member 14 on the installation surface S side is adjusted only by adjusting the level. The board casing 12 on the top 14 is easily made substantially horizontal ("easiness of leveling out"), and as a result, problems such as distortion of the casing and the door not being empty or not being closed can be suppressed.
This means that the level is set up before the installation on the base member 14 provided earlier, and thereafter the panel housing 12 and the panel member 13 are simply placed, which can be said to facilitate installation.
At the same time, unlike Patent Document 2, it is possible to reduce the height of the board housing 12 after the board housing 12 is installed, by the amount of the board member 13 and the base member 14 overlapping in the horizontal direction (“Installation”). Along with the height reduction "), the weight at the time of transportation is reduced by the amount of the base member 14 previously disposed on the installation surface S without transportation, and the load can be reduced (" reduction of the transportation load ").
又、土台部材１４で、金属製の部材のみを用いることによって、コンクリート製の基礎などの部材（コンクリート材）を用いなくとも良いため、コンクリート製の基礎の上面全体を削る等の作業が不要となり、コンクリート材が固まるまでの時間や、コンクリート材を固める型枠、その設置作業などが不要となり、設置容易化が図れる（「生コンレス」の実現）。 Also, by using only metal members for the base member 14, it is not necessary to use members (concrete materials) such as concrete foundations, so that work such as shaving the entire upper surface of the concrete foundations becomes unnecessary. In addition, the time required for the concrete material to harden, the formwork for hardening the concrete material, and the work of installing the same are not required, and the installation can be facilitated (realization of "concrete wrestling").
更に、土台部材１４を、設置面Ｓに打ち込まれた金属製の杭部材１５の上に、金属製の棒状部材１６を配設して構成することによって、「生コンレス」を実現すると同時に、杭部材１５を高さ調整するだけで、土台部材１４のレベル調整が可能となり、更なる「レベル出しの容易化」が図れる。
尚、土台部材１４を、杭部材１５及び棒状部材１６で構成した場合、上述した盤部材１３は、土台部材１４のうち棒状部材１６と、水平方向視で、重なる部分を有することとなる。
Further, by forming the base member 14 by arranging a metal rod-shaped member 16 on a metal pile member 15 driven into the installation surface S, the “raw concession” is realized, and Only by adjusting the height of the member 15, the level of the base member 14 can be adjusted, and "easiness of leveling" can be further improved.
When the base member 14 is composed of the pile member 15 and the bar-shaped member 16, the above-described board member 13 has a portion that overlaps with the bar-shaped member 16 of the base member 14 when viewed in the horizontal direction.
そして、土台部材１４を、棒状部材１６を盤筐体１２における所定一方向（盤筐体１２の後述する左右方向や前後方向など）に略沿ってのみ配設して構成することによって、土台部材１４が枠状である（盤筐体１２の左右方向に略沿った棒状部材１６だけでなく、盤筐体１２の前後方向に略沿った棒状部材１６も有する）場合と比べて、土台部材１４の重さが軽減できるため、土台部材１４の運搬容易化が図れる。 The base member 14 is formed by arranging the bar-shaped member 16 only substantially along one predetermined direction of the panel housing 12 (such as a left-right direction and a front-rear direction of the panel housing 12 to be described later). The base member 14 is compared with a case where the base member 14 has a frame shape (not only the bar member 16 substantially along the left and right direction of the panel housing 12 but also the bar member 16 substantially along the front and rear direction of the panel housing 12). Of the base member 14 can be easily transported.
本発明に係る盤設置システムによると、盤筐体側の盤部材と設置面側の土台部材を水平方向視で重ねることによって、「レベル出しの容易化」や「設置高さの低減」、「運搬負担の軽減」を実現できる。 ADVANTAGE OF THE INVENTION According to the board installation system which concerns on this invention, "easiness of leveling out", "reduction of installation height", "transportation" "Reduction of burden" can be realized.

The solar cell panel 20 in such a photovoltaic power plant 100 and a mount 21 for installing the solar cell panel 20 will be described below.
＜太陽電池パネル２０など＞
図２〜４に示したように、太陽電池パネル２０は、パネル状（平板状）であって、光が照射されることによって、正極（＋極）と負極（−極）の間に直流電力を発生し、発生する電力の平均は、約１００〜３００Ｗ（例えば、２５０Ｗ）である。
これらのうち、ある太陽電池パネル２０の＋極に別の太陽電池パネル２０の−極を接続し、別の太陽電池パネル２０の＋極にまた別の太陽電池パネル２０の−極を接続し、以下、これを繰り返して、複数枚（例えば、５〜２０枚）の太陽電池パネル２０を直列に接続して、１本の太陽電池ストリングとなる。
<Solar cell panel 20, etc.>
As shown in FIGS. 2 to 4, the solar cell panel 20 has a panel shape (a flat plate shape), and is irradiated with light so that a DC power is applied between a positive electrode (+ electrode) and a negative electrode (− electrode). And the average of the generated power is about 100 to 300 W (for example, 250 W).
Among these, the negative electrode of another solar cell panel 20 is connected to the positive electrode of another solar cell panel 20, the negative electrode of another solar cell panel 20 is connected to the positive electrode of another solar cell panel 20, Hereinafter, by repeating this, a plurality of (for example, 5 to 20) solar cell panels 20 are connected in series to form one solar cell string.
このように、複数枚の太陽電池パネル２０が直列に繋がった太陽電池ストリング全体としての＋極（電力出力端）と、−極（グランド端）の間の電圧は、各太陽電池パネル２０で発生された直流電圧の和であって、天候、時刻や、各太陽電池パネル２０の劣化、故障、設置位置のズレなどで変動するが、約２００〜１０００Ｖとなる。
又、太陽電池ストリングの電力出力端から出力される電力は、各太陽電池パネル２０の電力の和であって、約５００〜６０００Ｗ（例えば、出力電力が２５０Ｗの太陽電池パネル２０を１４枚接続した場合、３５００Ｗ＝３．５ｋＷ）となる。
As described above, the voltage between the positive pole (power output end) and the negative pole (ground end) of the entire solar cell string in which a plurality of solar cell panels 20 are connected in series is generated in each solar cell panel 20. The DC voltage is about 200 to 1000 V, which fluctuates due to weather, time, deterioration or failure of each solar cell panel 20, deviation of the installation position, and the like.
The power output from the power output terminal of the solar cell string is the sum of the power of each solar cell panel 20 and is about 500 to 6000 W (for example, 14 solar cell panels 20 having an output power of 250 W are connected. In this case, 3500 W = 3.5 kW).
ここで、太陽電池パネル２０を直列に接続するということは、それらの太陽電池パネル２０のうち１つでも不具合のある太陽電池パネル２０が発生すると、その太陽電池パネル２０において電流が遮断されてしまい、他の太陽電池パネル２０により発電された電力を出力することが困難となる。
そのため、直列に接続された太陽電池パネル２０ごとに、バイパスダイオード（図示省略）を設けることで、不具合の発生した太陽電池パネル２０を、電流が、バイパス（迂回）するように構成される。
Here, connecting the solar cell panels 20 in series means that if any one of the solar cell panels 20 has a defect, the current is cut off in the solar cell panel 20. Therefore, it is difficult to output the power generated by the other solar cell panel 20.
Therefore, by providing a bypass diode (not shown) for each of the solar cell panels 20 connected in series, the current is bypassed (bypassed) through the defective solar cell panel 20.
尚、このバイパスダイオードは、太陽電池パネル２０に対して、その−極から＋極へ電流が流れる向きに並列に接続され、詳しくは、バイパスダイオードのカソード（陰極）が、太陽電池パネル２０の＋極に接続され、バイパスダイオードのアノード（陽極）が、太陽電池パネル２０の−極に接続される。
このような太陽電池パネル２０を設置する際の架台２１や、その設置面Ｓについて、以下に述べる。
The bypass diode is connected in parallel to the solar cell panel 20 in a direction in which a current flows from the negative pole to the positive pole. More specifically, the cathode of the bypass diode is connected to the + of the solar cell panel 20. The anode of the bypass diode is connected to the negative pole of the solar cell panel 20.

The board member 13 may have any configuration as long as the board member 13 has a portion that overlaps with a base member 14 to be described later when viewed in the horizontal direction. A predetermined separate member attached to the lower surface (the lower surface) or a member protruding downward from the lower portion (lower surface) of the panel housing 12 (for example, the lower portion of the panel housing 12 is deformed to protrude downward) may be used. .
Hereinafter, the board member 13 will be mainly described as a rod-shaped member (column-shaped member) attached to the lower surface of the board housing 12 from below.
In addition, even when the board member 13 which is a rod-shaped member is attached to the lower part of the board housing 12 from below, the board member 13 naturally projects downward from the board housing 12.
棒状部材である盤部材１３は、その断面形状に限定はないが、例えば、断面略コ字状（断面が角張った溝状）であったり、断面略Ｈ字状であったり、略矩形状（略ロ字状）や断面略Ｌ字状であっても良い。
棒状部材である盤部材１３は、当然に長手方向を有しているが、その長手方向が、盤筐体１２の長手方向（盤筐体１２が左右に長ければ、左右方向）に略沿ってのみ配設されたり、盤筐体１２の長手方向と略直交する方向（盤筐体１２が左右に長ければ、前後方向）等に略沿ってのみ配設されるなど、盤筐体１２における所定一方向に略沿ってのみ配設されていても良い。
The board member 13, which is a rod-shaped member, is not limited in its cross-sectional shape. For example, the cross-sectional shape is substantially U-shaped (a groove having a square cross section), substantially H-shaped, or substantially rectangular ( It may be substantially L-shaped or a substantially L-shaped cross section.
The board member 13 which is a rod-shaped member naturally has a longitudinal direction, and the longitudinal direction is substantially along the longitudinal direction of the board housing 12 (the left-right direction if the board housing 12 is long to the left and right). Only in a direction substantially perpendicular to the longitudinal direction of the panel housing 12 (or in the longitudinal direction if the panel casing 12 is long in the left and right directions). It may be provided only substantially along one direction.
棒状部材である盤部材１３は、１つの盤筐体１２に対して、１つ（１本）だけ配設されていても良いが、複数配設されていても良く、例えば、盤筐体１２が左右に長ければ、当該盤筐体１２下部における前端に左右方向に略沿って棒状部材である盤部材１３が１つ配設され、盤筐体１２下部における後端に左右方向に略沿ってまた別の棒状部材である盤部材１３がもう１つ配設されていても良い。

Further, they may be arranged substantially parallel to each other.
In addition, when the number of the board members 13 as the bar members is four, a frame shape (to be substantially rectangular) is provided below the board housing 12 in the left-right direction and the front-back direction of the board housing 12. They may be arranged substantially along.

尚、このような盤部材１３の上下長さは、後述する土台部材１４の上下長さより短くても良く、このようにすることで、盤筐体１２を設置した後に、盤部材１３と、土台部材１４（例えば、後述する杭部材１５の頭部１５ｂ）との間に隙間１３ａが設けられ（図１、６参照）、この隙間１３ａによって、レベル出しをした土台部材１４に設置した盤筐体１２が、仮に略水平になっていなかったり、捻れが生じる等であっても、レベル出しをした土台部材１４に沿って盤筐体１２も略水平となり易くなる。
Hereinafter, the board member 13 which is a rod-shaped member will be mainly described assuming that its longitudinal direction is disposed substantially only along the longitudinal direction of the board housing 12.

In this manner, after the board housing 12 is installed, the A gap 13a is provided between the member 14 (for example, a head 15b of a pile member 15 described later) (see FIGS. 1 and 6). Even if the panel 12 is not substantially horizontal or twisted, the board housing 12 is also likely to be substantially horizontal along the leveled base member 14.
＜土台部材１４＞
図１〜７に示したように、土台部材１４は、設置面Ｓ側に設けられ、且つ、上述した盤筐体１２を下方から支持する部材であって、上述した盤部材１３と、水平方向視で、重なる部分を有している。
土台部材１４は、上述した盤部材１３と、水平方向視で、重なる部分を有していれば、何れの構成であっても良いが、例えば、土台部材１４は、金属製の部材のみが用いられていたり、後述するように、設置面Ｓに打ち込まれた金属製の杭部材１５の上に、金属製の棒状部材１６を配設して構成されていても良い。

The base member 14 may have any configuration as long as the base member 14 has a portion that overlaps with the above-described board member 13 when viewed in the horizontal direction. For example, the base member 14 uses only a metal member. Alternatively, as described later, a metal bar-shaped member 16 may be arranged on a metal pile member 15 driven into the installation surface S.
その他、図６に示したように、土台部材１４は、後述する杭部材１５及び棒状部材１６と、コンクリート製の基礎１４ａを組み合わせたもので構成されていても良い。

The base 14a may be a solid base having a uniform thickness and a substantially horizontal upper surface, or a getter base having a recess 14b or the like so as to form a space below the panel housing 12. In the recess 14b in this case, a cable from the solar cell panel 20 or the like outside the panel housing 12 (the switchboard 11), a power distribution cable from the inside of the panel housing 12 (the switchboard 11), or another cable is provided. A plurality of panel housings 12 (such as a power distribution panel 11 described later) and a cable to the power transmission panel may be provided.
その他、図７に示したように、土台部材１４は、後述する杭部材１５及び棒状部材１６は用いず、凹み１４ｂを有したコンクリート製の基礎１４ａだけで構成されていても良い。
この場合を詳解すれば、基礎１４ａは、設置面Ｓ上に設けられ且つ盤筐体１２の下方に空間を形成するよう凹み１４ｂ等を有したゲタ基礎であって、凹み１４ｂに、上述した盤部材１３が入った状態で、盤筐体１２が基礎１４ａを介して設置面Ｓに設置される。
In addition, as shown in FIG. 7, the base member 14 may be formed only of the concrete foundation 14 a having the recess 14 b without using the later-described pile member 15 and the bar-shaped member 16.
If this case is explained in detail, the foundation 14a is a getter foundation provided on the installation surface S and having a recess 14b or the like so as to form a space below the board housing 12, and the recess 14b is provided with the above-described board. With the member 13 inserted, the panel housing 12 is installed on the installation surface S via the foundation 14a.
尚、この場合も、凹み１４ｂに入った盤部材１３と、土台部材１４である基礎１４ａの凹み１４ｂ以外の部分が、水平方向視で重なる部分を有するため、「盤部材１３と、土台部材１４が、水平方向視で、重なる部分を有する」と言える。
故に、特許文献２とは異なって、凹み１４ｂに入った盤部材１３と、土台部材１４である基礎１４ａの凹み１４ｂ以外の部分が水平方向視で重なった分だけ、盤筐体１２を設置した後の高さを低くすることが可能となる（「設置高さの低減」）と共に、運搬しなくて済む土台部材１４の分だけ運搬時の重さが減り、負担を軽減できる（「運搬負担の軽減」）。
以下は主に、土台部材１４は、設置面Ｓに打ち込まれた金属製の杭部材１５の上に、金属製の棒状部材１６を配設して構成されているとして述べる。
Also in this case, since the board member 13 that has entered the recess 14b and a portion other than the recess 14b of the foundation 14a that is the base member 14 have a portion that overlaps in a horizontal direction, the “board member 13 and the base member 14 Has an overlapping portion when viewed in the horizontal direction. "
Therefore, unlike Patent Literature 2, the panel housing 12 is installed by an amount corresponding to the portion of the board member 13 that has entered the recess 14b and the portion other than the recess 14b of the foundation 14a that is the base member 14 when viewed in the horizontal direction. The height afterward can be reduced (“reduction in installation height”), and the weight during transportation is reduced by the amount of the base member 14 that does not need to be transported, so that the burden can be reduced (“transportation burden”).

As shown in FIGS. 1 to 6, the bar-shaped member 16 is made of metal and disposed on the above-described pile member 15 (particularly, the head 15 b). The rod-shaped member 16 naturally has a longitudinal direction.
The rod-shaped member 16 may have any configuration as long as it is disposed on the pile member 15. However, the rod-shaped member 16 is disposed substantially only in one predetermined direction in the panel housing 12. It does not matter.
ここで、「棒状部材１６が盤筐体１２における所定一方向に略沿う」とは、棒状部材１６の長手方向が、盤筐体１２における所定一方向に略沿うとの意味である。
又、本発明における「盤筐体１２における所定一方向」とは、上述したように、盤筐体１２における左右方向や、前後方向、上下方向、斜め方向などのうち、何れか一方向であるが、棒状部材１６が略沿う方向は、盤筐体１２の長手方向（盤筐体１２が左右に長ければ、左右方向）であっても良い。
Here, “the rod-shaped member 16 substantially extends in one predetermined direction of the panel housing 12” means that the longitudinal direction of the rod-shaped member 16 substantially extends in the predetermined one direction of the panel housing 12.
Further, the “predetermined one direction in the panel housing 12” in the present invention is, as described above, one of the left-right direction, the front-rear direction, the vertical direction, the oblique direction, and the like in the panel housing 12. However, the direction along which the bar-shaped member 16 substantially extends may be the longitudinal direction of the panel housing 12 (the left-right direction if the panel housing 12 is long in the left and right directions).
棒状部材１６は、その断面形状に限定はないが、例えば、断面略Ｈ字状であったり、断面略コ字状（断面が角張った溝状）であったり、略矩形状（略ロ字状）や断面略Ｌ字状であっても良い。
棒状部材１６は、１つの盤筐体２を設置する設置面Ｓに対して、１つ（１本）だけ配設されていても良いが、複数配設されていても良く、例えば、設置後の盤筐体１２の長手方向に略沿う方向で、且つ、盤筐体１２の前側に左右方向に略沿って棒状部材１６が１つ配設され、盤筐体１２の後側に左右方向に略沿ってまた別の棒状部材１６がもう１つ配設されていても良い。
The bar-shaped member 16 is not limited in its cross-sectional shape. For example, the bar-shaped member 16 has a substantially H-shaped cross section, a substantially U-shaped cross section (a groove having a square cross section), or a substantially rectangular shape (substantially R-shaped). ) Or a substantially L-shaped cross section.
One (one) bar member 16 may be provided on the installation surface S on which one panel housing 2 is installed, but a plurality of the bar members 16 may be provided. One bar-shaped member 16 is disposed in a direction substantially along the longitudinal direction of the panel casing 12 and substantially in the left-right direction on the front side of the panel casing 12, and in the left-right direction on the rear side of the panel casing 12. Another rod-shaped member 16 may be disposed substantially along the other.
この場合、２つの棒状部材１６は、略平行に、設置面Ｓに打ち込まれた各杭部材１５上に配設されることとなる。
又、棒状部材１６が３つ以上である場合には、例えば、設置後の盤筐体１２の長手方向に略沿う方向で、且つ、盤筐体１２の前側から後側にかけて、所定間隔ごとに且つ互いに略平行に配設されていても良い。
In this case, the two bar-shaped members 16 are arranged substantially in parallel on the pile members 15 driven into the installation surface S.
When the number of the rod-shaped members 16 is three or more, for example, at a predetermined interval in a direction substantially along the longitudinal direction of the panel housing 12 after installation and from the front side to the rear side of the panel housing 12. Further, they may be arranged substantially parallel to each other.
尚、棒状部材１６は４つであっても良く、この場合には、設置面Ｓに打ち込まれた各杭部材１５上に、枠状に（略矩形状となるように）、当該盤筐体１２の左右方向及び前後方向に略沿って配設されていても良い。
又、このような棒状部材１６の上下長さは、上述した盤部材１３の上下長さより長くても良く、このようにすることで、上述したように、盤筐体１２を設置した後に、盤部材１３と、杭部材１５の頭部１５ｂとの間に隙間１３ａが設けられる（図１、６参照）。
The number of the rod-shaped members 16 may be four. In this case, the board housing is formed in a frame shape (to be substantially rectangular) on each of the pile members 15 driven into the installation surface S. 12 may be disposed substantially along the left-right direction and the front-back direction.
Further, the vertical length of such a bar-shaped member 16 may be longer than the vertical length of the above-described board member 13, and in this manner, as described above, after the A gap 13a is provided between the member 13 and the head 15b of the pile member 15 (see FIGS. 1 and 6).
＜その他＞
本発明は、前述した実施形態に限定されるものではない。盤設置システム１０等の各構成又は全体の構造、形状、寸法などは、本発明の趣旨に沿って適宜変更することが出来る。
図１〜７に示したように、盤設置システム１０は、盤筐体１２を設置面Ｓに設置した後等に、棒状留め部材１７を、その長手方向が盤筐体１２の前後方向に略沿うように、当該盤筐体１２下部の上から、ボルト等の固定部材で取り付けても良い。
<Others>
The present invention is not limited to the embodiments described above. Each configuration of the panel installation system 10 or the like or the entire structure, shape, dimensions, and the like can be appropriately changed in accordance with the gist of the present invention.
As shown in FIGS. 1 to 7, after the panel housing 12 is installed on the installation surface S or the like, the panel mounting system 10 moves the bar-shaped fastening member 17 such that the longitudinal direction thereof is substantially in the front-rear direction of the panel housing 12. It may be attached along the lower part of the panel housing 12 with a fixing member such as a bolt so as to follow the same.
この場合の棒状留め部材１７は、その断面形状に限定はないが、例えば、断面略Ｈ字状であったり、断面略コ字状（断面が角張った溝状）であったり、略矩形状（略ロ字状）や断面略Ｌ字状であっても良い。
盤筐体１２は、パワーコンディショナのみを有した（内蔵した）パワコン筐体であっても良い。
The cross-sectional shape of the rod-shaped fastening member 17 in this case is not limited. For example, the cross-sectional shape is substantially H-shaped, substantially U-shaped (groove having a square cross section), or substantially rectangular ( It may be substantially L-shaped or a substantially L-shaped cross section.
The panel housing 12 may be a power control housing having (built-in) only a power conditioner.
土台部材１４は、杭部材１５を用いず、コンクリート製の基礎１４ａと棒状部材１６で構成されていても良く、土台部材１４が基礎１４ａと棒状部材１６で構成される場合、棒状部材１６は、基礎１４ａの上に配設されていても構わない。
更に、この場合、基礎１４ａは、必ずしも凹み１４ｂを有さずとも良く、棒状部材１６は、基礎１４ａ上に配設しても構わない。
尚、この場合、盤部材１３と、土台部材１４である棒状部材１６が、水平方向視で重なる部分を有することとなるが、特許文献１とは異なり、盤部材１３及び棒状部材１６を介して、盤筐体１２を設置面Ｓに設置するため、設置面Ｓ側の棒状部材１６をレベル調整しておくだけで、当該棒状部材１６上の盤筐体１２が容易に略水平となり（「レベル出しの容易化」）、その結果、筐体の歪みや、扉が空かない、閉まらない等の問題も抑制できる。
これと同時に、特許文献２とは異なり、盤部材１３と棒状部材１６の水平方向視で重なった分だけ、盤筐体１２を設置した後の高さを低くすることが可能となる（「設置高さの低減」）と共に、運搬せず予め設置面Ｓに配設する棒状部材１６の分だけ運搬時の重さが減り、負担を軽減できる（「運搬負担の軽減」）。
この他、土台部材１４は、杭部材１５やコンクリート製の基礎１４ａを用いず、棒状部材１６（金属製の棒状部材１６）だけで構成されていても良く、この場合、棒状部材１６は、設置面Ｓの上に配設されていても構わない。
The base member 14 may be constituted by a concrete foundation 14a and a rod-shaped member 16 without using the pile member 15, and when the base member 14 is constituted by the foundation 14a and the rod-shaped member 16, the rod-shaped member 16 It may be arranged on the foundation 14a.
Furthermore, in this case, the foundation 14a does not necessarily have to have the recess 14b, and the rod-shaped member 16 may be provided on the foundation 14a.
Note that, in this case, the board member 13 and the bar-shaped member 16 as the base member 14 have a portion that overlaps when viewed in the horizontal direction. However, unlike Patent Document 1, the board member 13 and the bar-shaped member 16 are interposed. In order to install the panel housing 12 on the installation surface S, simply adjusting the level of the bar-shaped member 16 on the installation surface S side makes the panel housing 12 on the bar-shaped member 16 easily substantially horizontal (see “Level As a result, it is possible to suppress problems such as distortion of the housing and a problem that the door is not open or closed.
At the same time, unlike Patent Literature 2, the height of the board housing 12 after the board housing 12 is installed can be reduced by the overlap of the board member 13 and the bar-shaped member 16 when viewed in the horizontal direction (“Installation”). Along with the height reduction "), the weight at the time of transportation is reduced by the amount of the bar-shaped member 16 previously disposed on the installation surface S without transportation, and the load can be reduced (" reduction of the transportation load ").
In addition, the base member 14 may be constituted only by the rod-shaped member 16 (metal-made rod-shaped member 16) without using the pile member 15 or the concrete foundation 14a. In this case, the rod-shaped member 16 is installed. It may be arranged on the surface S.
盤設置システムは、配電盤だけでなく、送電盤やパワコン盤など、何れの盤筐体に対しても利用可能であり、又、太陽光発電プラントなどに対して、その発電量や規模に関わらず利用でき、太陽光発電プラント以外に、風力、水力、波力等によって回転される発電機（モータ）によって発電するプラントにおいて使用でき、屋外・屋内を問わず利用可能である。 The panel installation system can be used not only for switchboards, but also for any panel housing, such as power transmission panels and power control panels. It can be used in plants that generate electricity by a generator (motor) that is rotated by wind power, water power, wave power, and the like, in addition to solar power plants, and can be used outdoors or indoors.
