Description

【0001】
【発明の属する技術分野】
本件の発明は,分電盤の分岐回路の接続チェック方法に係わる。
【0002】
【従来の技術】
従来,建物の電気設備工事の竣工検査などにおいて,分電盤の負荷側の配線接続チェックは,分電盤と接続配線端末に人が分かれて分岐ブレーカー1回路づつ声を掛け合いながら各々の配線が指定された分岐ブレーカーに接続されているかを,実際に電気を入れながらチェックしていた。
【0003】
【発明が解決しようとする課題】
しかしながら,例えば建物が集合住宅など,分電盤の設置数量がたくさんある場合には,それぞれの分電盤全てについて分岐ブレーカの配線接続をチェックしていくのは,非常に多くの時間と人手がかかる作業となっていた。
【0004】
【本件発明の目的】
そこで,本件発明の目的は,ひとつの分電盤に接続される配線については,一人で行え,集合住宅などでも人手を省力化できるようなチェック装置を提供することにある。
【0005】
【課題を解決しようとするための手段】
そこで,本件発明の請求項1のチェック装置は,建築物に設置されて配線工事された,複数の分岐ブレーカを備えた分電盤の,各々の分岐ブレーカの負荷側端子部には,分岐ブレーカのハンドルを切りにして,分岐ブレーカの負荷側端子以下の配線を電源側配線から切り離した状態で,各々異なる値のインピーダンス回路を着脱自在に接続し,コンセントや照明器具などの配線端末には,前記インピーダンスを測定する回路を備えた測定器を着脱自在に接続して,配線端末に接続したインピーダンスの測定結果から,コンセントや照明器具が,指定された分岐ブレーカに接続されているかどうかを判断可能としたものである。
【0006】
また,請求項2によるチェック装置は,建築物に設置されて配線工事された,複数の分岐ブレーカを備えた分電盤の,各々の分岐ブレーカの負荷側端子部には,分岐ブレーカのハンドルを切りにして,分岐ブレーカの負荷側端子以下の配線を電源側配線から切り離した状態で,各々異なる抵抗値の抵抗器とダイオード手段を直列もしくは並列に組み合わせた回路を,ダイオードの極性をそろえて着脱自在に接続し,コンセントや照明器具などの配線端末には,前記抵抗器の抵抗値を測定判別する回路とダイオード手段の極性を判別するランプを備えた回路切り替えスイッチにより択一的に選択し,電池を介して配線に接続する測定器を着脱自在に接続して,配線端末に接続した測定器の抵抗値の測定結果とダイオードの極性の判別結果から,コンセントや照明器具が,指定された分岐ブレーカに接続されているかどうかを判断可能としたものである。
【0007】
【作用】
請求項1と2による本件発明によれば,電気設備の竣工検査の際に,分電盤には前記インピーダンス回路または抵抗器とダイオード手段の組み合わせ回路を予め分電盤の分岐ブレーカの負荷側端子に装着しておき,その後,測定器でコンセントや,照明器具などの配線端末側から接続されているインピーダンス回路や抵抗器とダイオード手段の組み合わせ回路のインピーダンスや抵抗値を測定することで,その配線がどの分岐ブレーカに接続されているかを容易に判別可能であるので,接続チェックが一人でできる。
【0008】
また,請求項2による発明では,配線がどの分岐ブレーカに接続されているかを確認後,ダイオード手段の接続極性をチェックすれば,コンセントなどのどちらの極が分岐ブレーカのどちらの極につながっているかといった接続極性のチェックも可能となる。
【0009】
【発明の実施の形態】
以下に本件発明を図面を用いて詳細に説明する。
【0010】
図1に本件発明のチェック装置の第一の実施例を示す。図1において1は分電盤で,2〜4は複数の分岐ブレーカ,8〜10は配線で11〜13は配線の端末に設置されたコンセントや,照明器具などの接続器で,予め定められた配線図により個々の分岐ブレーカにどのコンセントや照明器具が接続するかが指定されており,工事終了後,11〜13がそれぞれうまく2〜4の分岐ブレーカに対応して接続されているかをチェックするものである。
【0011】
14〜16は各々の分岐ブレーカの負荷側の端子5〜7に着脱可能なインピーダンス回路で,各々の分岐ブレーカごとにそれぞれインピーダンスの値を変えてある。17はインピーダンス測定回路を備えた測定器である。
【0012】
接続チェックの際には,次のように一人で作業が行える。まず,分岐ブレーカ2〜4をハンドルを切りにして,分岐ブレーカの負荷側端子5〜7以下の配線を電源側配線18から切り離す。その後14〜16のインピーダンス回路を分岐ブレーカの負荷側端子5〜7に接続し,配線端末11〜13側に移動する。移動後,測定器を個々の配線端末に接続し配線端末からインピーダンス回路のインピーダンスを測定して,インピーダンス値によりその配線がどの分岐ブレーカに接続されているかを判断して接続をチェックする。
【0013】
図2に,本件発明による第二の実施例を示す。図2において,図1と同一記号の個所は図1ですでに説明したものと同一であるので説明を省略する。20〜22は抵抗器201,211,221とダイオード手段202,212,222による組み合わせ回路で,201〜221の抵抗器の抵抗値はそれぞれ異なる値としてある。24は抵抗値測定回路242と極性判定回路243と切り替えスイッチ241とからなる測定器で,チェック方法は図1に示す装置と同様であるが,まず,切替スイッチ241を抵抗値測定回路側にしておいて配線が接続してある抵抗値を測定して,配線が接続してある分岐ブレーカのチェックを行い,次に切替スイッチ241を極性判定回路側に切り替え,ランプが点灯するかどうかをチェックすることで,配線端末の右側が分岐ブレーカの右側の極に接続されているかどうかが分かる。ダイオード手段202〜222の極性を分岐ブレーカ2〜4の端子の左右方向に対し一定の基準でそろえておけば,確実に接続極性の判定が可能になる。
【0014】
図3は,は20〜22の抵抗器とダイオード手段の組み合わせ回路の別の実施例で,抵抗器251とダイオード手段252を直列に接続した例である。図4は抵抗器とダイオード手段が図3に示す場合の測定器26の例で,切替スイッチ261と抵抗値測定回路262と極性判別回路(この例ではランプ)263と電池264を図のように接続してある。この場合抵抗値測定回路262は流れる電流値で抵抗値を測定するような構成となる。
【0015】
【発明の効果】
以上のように,本件発明によれば,分電盤の負荷端子側にインピーダンス回路もしくは抵抗器とダイオード手段の組み合わせ回路を着脱自在に接続し,配線の端末側から測定器で,配線が接続されているインピーダンス回路もしくは抵抗器とダイオード手段による回路のインピーダンスもしくは抵抗値を測定することで,一人で順番にチェック作業が行えチェック作業にたくさんの人手をかけずに容易に接続回路のチェックが行えるという効果がある。
【0016】
また,ダイオード手段によるダイオードの接続極性を測定器でチェックすれば,配線とブレーカ端子の接続極性のチェックも容易に行えるという効果を有する。
