Description

本発明は、太陽光発電設備の点検をし易くするために、太陽電池モジュールとパワーコンディショナーとの間に配置される太陽光発電用点検盤に関する。 The present invention relates to a photovoltaic power generation inspection panel arranged between a solar cell module and a power conditioner in order to facilitate inspection of a photovoltaic power generation facility.

太陽光発電設備において、太陽光発電モジュールの発電特性が正常か否か確認する為の定期点検内容として、太陽光発電モジュールのＩ−Ｖ特性を調べる項目がある。
従来のこのＩ−Ｖ特性測定は、太陽光発電モジュールからのケーブルを集約する接続箱などにおいて、例えばストリング毎、或いは複数のストリングから成る太陽電池アレイ毎に測定が行われた。
接続箱には、ストリング毎に或いはアレイ毎に開閉器が設けられている（例えば、特許文献１参照）ため、パワーコンディショナとの接続を切り離しでき、容易にＩ−Ｖ特性を測定することができた。 In a photovoltaic power generation facility, there is an item to check the IV characteristic of the photovoltaic power generation module as a regular inspection content for confirming whether or not the power generation characteristic of the photovoltaic power generation module is normal.
The conventional IV characteristic measurement is performed, for example, for each string or for each solar cell array including a plurality of strings in a connection box or the like in which cables from the solar power generation module are aggregated.
Since a switch is provided in the connection box for each string or for each array (for example, refer to Patent Document 1), the connection with the power conditioner can be disconnected, and the IV characteristic can be easily measured. did it.

近年の規模の小さい太陽光発電システムでは、接続箱を設けずに複数設置された太陽電池ストリングの出力を直接パワーコンディショナに送り、パワーコンディショナにおいて１ラインにまとめて交流変換する構成が普及している。
太陽電池ストリングのＩ−Ｖ特性の測定作業は、発電中にパワーコンディショナから切り離して行う必要があるにもかかわらず、このような接続箱の無いシステム構成の場合、パワーコンディショナに接続されているケーブルを切り離す開閉手段等が無い。そのため、ケーブルを端子から取り外して行われたが、切り離す際にアーク放電を伴うなどの危険があったし、ケーブルを取り外す作業も面倒であった。 In the recent small-scale photovoltaic power generation systems, a configuration in which the output of a plurality of solar cell strings installed directly without connecting boxes is directly sent to the power conditioner, and AC conversion is collectively performed in one line in the power conditioner has become popular. ing.
Although the measurement of the IV characteristics of the solar cell string must be performed separately from the power conditioner during power generation, in the case of a system configuration without such a junction box, it must be connected to the power conditioner. There is no opening/closing means to disconnect the existing cable. Therefore, the cable was removed from the terminal, but there was a risk of arc discharge when disconnecting the cable, and the work of removing the cable was troublesome.

更に、取り外したケーブルは、太陽電池が発電状態にあるにも関わらず固定されない状態となるため、その安全対策が求められた。また、測定器は首から提げたとしても片手で持つ必要があるため測定はもう一方の手で行われ、測定プローブ２本を片手で持って測定対象のストリングのプラス／マイナスの端子に当てて計測していた。このように、作業者に対して負担が大きく、改善が求められた。 Further, since the detached cable is in a state where it is not fixed even though the solar cell is in a power generating state, a safety measure is required. Also, even if the measuring instrument is held from the neck, it is necessary to hold it with one hand, so the measurement is performed with the other hand. Hold two measuring probes with one hand and apply them to the plus/minus terminals of the string to be measured. I was measuring. As described above, the burden on the worker is great and improvement is required.

そこで、本発明はこのような問題点に鑑み、接続箱の無い太陽光発電設備であっても、Ｉ−Ｖ特性の測定を容易に実施できる太陽光発電用点検盤を提供することを目的としている。 Then, in view of such a problem, the present invention has an object to provide a photovoltaic power generation inspection panel that can easily measure the IV characteristics even in a photovoltaic power generation facility without a junction box.

以下、本発明を具体化した実施の形態を、図面を参照して詳細に説明する。図１は本発明に係る太陽光発電用点検盤の一例を示し、扉を開けた状態の外観説明図である。
太陽光発電用点検盤（以下、単に「点検盤」と称する。）１０は、図１に示すように前面が開口された箱状の本体２と、開口された本体２の前面を閉塞する扉３とから成るキャビネット１内に、複数の直流開閉器４が組み付けられている。
そして、本体２の内部全体には、直流開閉器４のみ露出させて配線を隠すための配線覆い５が配置されている。また、列設された直流開閉器４の前面には直流開閉器４を保護する保護カバー６が配置されている。 Hereinafter, embodiments that embody the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example of a photovoltaic power generation inspection panel according to the present invention, and is an external view for explaining a state in which a door is opened.
A photovoltaic power generation inspection panel (hereinafter, simply referred to as “inspection panel”) 10 includes a box-shaped main body 2 having an open front surface as shown in FIG. 1, and a door closing the front surface of the opened main body 2. A plurality of DC switches 4 are assembled in a cabinet 1 composed of 3 and 3.
Further, a wiring cover 5 for exposing only the DC switch 4 and hiding the wiring is arranged in the entire main body 2. A protective cover 6 for protecting the DC switches 4 is arranged on the front surface of the DC switches 4 arranged in a row.

直流開閉器４は、太陽電池ストリング（図２に示す）１１毎に設けられ、太陽電池ストリング１１の回路数に合わせて複数設置され、一列に並べて組み付けられている。
この直流開閉器４は、一次側端子４ａの上部（点検盤１０に組み付けた状態で前方を向く部位）が露出しており、点検盤１０に組み付けた状態で一次側端子４ａの端子金具を前方から視認できるよう構成されている。 The DC switch 4 is provided for each solar cell string 11 (shown in FIG. 2 ), a plurality of DC switchgears 4 are installed according to the number of circuits of the solar cell string 11, and they are assembled in a line.
In this DC switch 4, the upper part of the primary side terminal 4a (the part facing forward when assembled to the inspection panel 10) is exposed, and the terminal metal fitting of the primary side terminal 4a is installed forward when assembled to the inspection panel 10. It is configured to be visible from.

保護カバー６は、１列に並べて組み付けられた直流開閉器群Ｓの全体を覆う１枚の半透明の合成樹脂板で形成され、４隅が配線覆い５に固定されている。配線覆い５の直流開閉器群Ｓの周囲となる４カ所には、前方に向けて起立形成された４本の支柱５ａが配置され、この支柱５ａを介して保護カバー６は配線覆い５に取り付けられている。支柱５ａとの連結部のうち、下部の左右２カ所は支柱５ａに蝶着部材７を介して蝶着され、上部の左右２カ所は支柱５ａから分離可能に連結されている。尚、配線覆い５は本体２に連結されている。 The protective cover 6 is formed of a single semitransparent synthetic resin plate that covers the entire DC switch group S assembled side by side in one row, and its four corners are fixed to the wiring cover 5. Four pillars 5a that are erected forward are arranged at four places around the DC switch group S of the wire covering 5, and the protective cover 6 is attached to the wire covering 5 through the pillars 5a. Has been. Of the connecting portion with the support column 5a, two lower left and right portions are hinged to the support column 5a via the hinge members 7, and two upper left and right portions are detachably connected from the support column 5a. The wiring cover 5 is connected to the main body 2.

そのため、保護カバー６の上部の連結を解除すれば、下部の蝶着部材７を中心に回動可能となり、保護カバー６は上端を前方に引き出して傾倒させることができる。
但し、蝶着部材７は開閉角を制限しており、９０度以上は開動作しないよう構成されており、保護カバー６を回動して水平な状態まで傾倒したらそれ以上回動せず、水平な状態が維持され、作業台としての使用を可能としている。 Therefore, if the upper part of the protective cover 6 is released, it can be rotated around the lower hinged member 7, and the upper end of the protective cover 6 can be pulled forward and tilted.
However, the hinged member 7 limits the opening and closing angle and is configured not to open at 90 degrees or more, and when the protective cover 6 is rotated and tilted to a horizontal state, the hinged member 7 does not rotate any more and the horizontal position is reached. It remains in good condition and can be used as a workbench.

図２は点検盤１０を組み込んだ太陽光発電システムを示している。図２に示すように、点検盤１０は太陽電池ストリング１１とパワーコンディショナ１２の間に設置される。尚、個々の直流開閉器４の一次側端子４ａは太陽電池ストリング１１の出力回路であるケーブルが接続され、個々の二次側端子４ｂはパワーコンディショナ１２に接続される。 FIG. 2 shows a photovoltaic power generation system incorporating the inspection panel 10. As shown in FIG. 2, the inspection panel 10 is installed between the solar cell string 11 and the power conditioner 12. A cable that is an output circuit of the solar cell string 11 is connected to the primary side terminal 4a of each DC switch 4, and each secondary side terminal 4b is connected to the power conditioner 12.

上記の如く構成された点検盤１０を太陽光発電システムに組み込むことで、Ｉ−Ｖ特性の測定は以下の様に行われる。
システムが発電を行っている使用状態では、点検盤１０の扉３は閉じられた状態にある。そのため、Ｉ−Ｖ特性の測定を開始するにあたり、まず扉３を開ける。そして、保護カバー６を前方へ傾倒操作して回動し、直流開閉器４を露出させて操作可能とする。このとき、傾倒した保護カバー６は水平な状態が保持される。 By incorporating the inspection panel 10 configured as described above into the solar power generation system, the IV characteristic is measured as follows.
In the use state in which the system is generating electricity, the door 3 of the inspection panel 10 is closed. Therefore, when starting the measurement of the IV characteristic, the door 3 is first opened. Then, the protective cover 6 is tilted forward and rotated to expose the DC switch 4 so that it can be operated. At this time, the tilted protection cover 6 is maintained in a horizontal state.

次に、点検したい太陽電池ストリング１１が接続されている直流開閉器４をオフ操作して、太陽電池ストリング１１の出力回路をパワーコンディショナ１２から切り離す。Ｉ−Ｖ特性を計測する測定器（図示せず）は、水平な状態にある保護カバー６上に載置でき、載置することで両手をフリーにして計測作業を進める。
こうして、オフ操作した直流開閉器４の目視できる一次側端子４ａ等の端子金具へ図示しないプローブを当てることでＩ−Ｖ特性の計測を行う。 Next, the DC switch 4 to which the solar cell string 11 to be inspected is connected is turned off to disconnect the output circuit of the solar cell string 11 from the power conditioner 12. A measuring device (not shown) for measuring the IV characteristic can be placed on the protective cover 6 in a horizontal state, and by placing it, both hands are freed to proceed with the measurement work.
In this way, the IV characteristic is measured by applying a probe (not shown) to the terminal fittings such as the primary side terminal 4a of the DC switch 4 which has been turned off.

このように、太陽電池ストリングのＩ−Ｖ特性を測定する際は、パワーコンディショナ１２から切り離す必要があるが、直流開閉器４を開操作すれば太陽電池ストリング１１の出力をパワーコンディショナ１２から切り離しできるため、ケーブル自体を切り離す必要が無く、容易に測定できる。そして、測定するためにプローブを接触させる部位が前方から視認できるためプローブを当て易い。結果、従来より計測時間の大幅な短縮が可能となる。
また、キャビネット１内に作業台となる部材を備えているため、測定器を取り出した作業台に置くことで、作業者は両手を使って測定作業を行うことができ、Ｉ−Ｖ特性の計測等をスムーズに実施できる。
特に、直流開閉器４を保護する保護カバー６を作業台にすることで、別途部材を設ける必要が無い。 As described above, when measuring the IV characteristics of the solar cell string, it is necessary to disconnect from the power conditioner 12. However, if the DC switch 4 is opened, the output of the solar cell string 11 is output from the power conditioner 12. Since it can be disconnected, there is no need to disconnect the cable itself, and measurement can be performed easily. Further, since the portion to be brought into contact with the probe for measurement can be visually recognized from the front, the probe can be easily applied. As a result, the measurement time can be significantly shortened compared to the conventional case.
Further, since the cabinet 1 is provided with a member serving as a workbench, the worker can perform the measurement work with both hands by placing the measuring instrument on the workbench and measure the IV characteristic. Etc. can be carried out smoothly.
In particular, by using the protective cover 6 that protects the DC switch 4 as a workbench, it is not necessary to provide a separate member.

図３は点検盤１０の他の形態を示し、扉３を開けた状態の外観説明図である。上記図１とはキャビネット１、直流開閉器４等の構成は同様であり、作業台の構成が異なっている。以下相違点を説明する。
図３に示す様に、作業台として使用する専用の板部材１５が扉３の裏面に取り付けられている。この板部材１５は、下辺が扉３に蝶着されており、起立させて扉３の裏面に密着させた状態で収納されている。
蝶着するために使用されている蝶着部材１６は、板部材１５が水平な状態を維持するよう構成され、使用時は後方に回動して倒置することで水平な作業台が形成される。
このように、作業台専用の部材を組み付けても良く、扉３をあければ、作業台を取り出して測定器を載置して計測できるため、便利である。 FIG. 3 shows another form of the inspection panel 10 and is an external appearance view with the door 3 opened. The configuration of the cabinet 1, the DC switch 4 and the like is similar to that of FIG. 1, but the configuration of the workbench is different. The differences will be described below.
As shown in FIG. 3, a dedicated plate member 15 used as a workbench is attached to the back surface of the door 3. The plate member 15 has a lower side hinged to the door 3, and is housed in a state of standing upright and closely attached to the back surface of the door 3.
The hinged member 16 used for hinged attachment is constructed so that the plate member 15 is maintained in a horizontal state, and when used, it is pivoted backward and inverted to form a horizontal workbench. ..
As described above, a member dedicated to the workbench may be assembled, and if the door 3 is opened, the workbench can be taken out and a measuring instrument can be placed and measured, which is convenient.

図４は点検盤１０の更に他の形態を示し、上記図１とはキャビネット１の構成が異なり、扉３が下方に開く構成となっている。扉３は下部が本体２に蝶着されており、蝶着部材１７は扉３が水平になった状態を維持するよう構成されている。
このように、扉３を上方から開ける構造とし、開けた扉３を水平な状態に維持させれば作業台として使用でき、別途作業台として使用する部材を必要としない。 FIG. 4 shows still another form of the inspection panel 10. The cabinet 1 is different from that of FIG. 1 in that the door 3 is opened downward. The lower portion of the door 3 is hinged to the main body 2, and the hinged member 17 is configured to maintain the door 3 in a horizontal state.
In this way, if the door 3 is structured to be opened from above and the opened door 3 is maintained in a horizontal state, it can be used as a workbench, and a separate member used as a workbench is not required.

尚、図４の形態では、直流開閉器４を横向きにして縦方向に多数列設しているが、上記形態と同様に縦向きに配置して左右方向に列設させても良い。また、キャビネット１が縦長の場合は、扉３を上下２分割して上下方向に観音開きするよう構成し、下側の扉を作業台としても良い。
また上記実施形態は、何れも測定器を載置する作業台を備えているが、作業台は無くても良く、直流開閉器４を備えた点検盤１０を太陽光発電システムに介在させるだけで、Ｉ−Ｖ特性の測定は容易となり作業性は格段に改善される。
更に、直流開閉器４は、その一次側端子４ａがキャビネット１の前方から視認できる構成としているが、一次側端子４ａ自体は視認できなくとも良く、一次側端子４ａに電気的に接続された金具がキャビネット１の前方から視認できれば良い。結果、同様にプローブを接触させ易く、点検作業がし易い。 In addition, in the form of FIG. 4, the DC switches 4 are arranged in a horizontal direction and arranged in a large number in a vertical direction, but they may be arranged in a vertical direction and arranged in a horizontal direction in the same manner as the above-described form. In the case where the cabinet 1 is vertically long, the door 3 may be divided into upper and lower parts so as to open and close in a vertical direction, and the lower door may be used as a work table.
In addition, in each of the above-described embodiments, the work table on which the measuring device is placed is provided, but the work table may not be provided, and the inspection panel 10 provided with the DC switch 4 may be interposed in the solar power generation system. , IV characteristics can be easily measured, and workability is remarkably improved.
Further, although the DC switch 4 has a configuration in which the primary side terminal 4a thereof can be visually recognized from the front of the cabinet 1, the primary side terminal 4a itself may not be visually recognizable, and a metal fitting electrically connected to the primary side terminal 4a. Should be visible from the front of the cabinet 1. As a result, similarly, the probe can be easily brought into contact, and the inspection work can be easily performed.
