【発明の属する技術分野】
本発明は、配電盤内に収納されるフィーダ機器、母線の各室(コンパートメント)の配置に関するものである。
【0002】
【従来の技術】
図2は、従来の一般的な2フィーダ収納の2段積盤の構造を示す。
図2において、1は筺体、2a,2bは正面ドア、3a,3bは制御機器室、4a,4bは遮断器室、5は母線室、6はケーブル室、7は母線、8a,8bは変流器、9a,9bは外部端子、10a,10bはケーブル、11は後面ドア、12a,12bは後面保護カバー、13は母線室後面仕切板、14は母線固定ガイシ、15はガイシ取り付け板、16a,16bは遮断器である。
従来、盤内のコンパートメントの配置(側面から見た姿)は、正面ドア2a,2bを開けた内部に正面から後面に向かって、「制御機器室3a,3b」→「遮断器室4a,4b」→「母線室5」→「ケーブル室6」の順となり、母線7の相配置は、高さ方向一列としている。
各機器の盤内接続は、母線7から、「上下遮断器16a,16b」→「変流器8a,8b」→「外部端子9a,9b」へ接続され、外部端子9a,9bには、外部機器からのケーブルが接続される。また母線7は、図面と直角方向に隣接する他盤の母線と盤側面端部で接続される。
このような構成の配電盤における母線7の他盤との接続および点検作業は、盤後面から後面ドア11・後面保護カバー12a,12b・母線室仕切板13を取りはずして行う。
【0003】
【発明が解決しようとする課題】
しかしながら、このような従来の技術においては、次の理由により隣接する盤との母線接続作業・点検作業がやりずらいという問題があった。
(1)盤後面から母線7までの距離が遠い。
(2)母線7と作業者の間に「母線固定ガイシ14および取り付け板15」、「外部端子9b」、および「ケーブル10a,10b」が介在する。
(3)母線室後面の仕切板が取り外しにくい。
(4)遮断器室4a,4bと母線室5が前後方向に重なる為、盤奥行き寸法が大きくなる。
本発明は、このような問題を解決するためになされたもので、隣接する盤との母線接続作業・点検作業を容易に行うことができる配電盤を提供することを目的とするものである。
【0004】
【課題を解決するための手段】
上記問題点を解決するために、本発明は、筐体の前後にドアを有するとともに、筐体内に複数のフィーダ機器と各フィーダに電源を供給する母線を各々の室に区分して収納した多段積配電盤において、母線室を、上下各遮断器室の中間位置に配置するとともに、上側遮断器室の下面側にガイシ取付板を配置し、前記ガイシ取付板の下面に、2個の母線固定ガイシをそれぞれ垂直方向に向けて配置し、かつ、下側遮断器室の上面側に、1個の母線固定ガイシを、垂直方向に向けて配置し、さらに、前記1個の母線固定ガイシを、前記上側の2個の固定ガイシの下方に、空間を介して配置して、前記母線室内に収納した母線の相配置を、逆三角形状にしたものである。
【0005】
【発明の実施の形態】
以下、本発明の実施例を図に基づいて説明する。
図1は、本発明の実施例における配電盤を示す側断面図である。
図1において、1は筺体、2a,2bは正面ドア、3a,3bは制御機器室、4a,4bは遮断器室、5は母線室、6はケーブル室、7は母線、8a,8bは変流器、9a,9bは外部端子、10a,10bはケーブル、11は後面ドア、12a,12bは後面保護カバー、13は母線室後面仕切板、14は母線固定ガイシ、15はガイシ取り付け板、16a16bは遮断器、17は母線室正面カバーである。
配電盤内のコンパートメントの配置(側面から見た姿)は、正面ドア2a,2bを開けた内部に正面から後面に向かって「制御機器室3a,3b」→「遮断器室4a,4b+母線室5」→「ケーブル室6」の順となり、母線室5は上下遮断器室4a,4b間のスペースに配置し、母線7の相配置は、▽状にしており、従来とは母線室5の配置、母線7の相配置および母線7から遮断器16a,16bへの接続方法が異なる。
母線室5の正面側には、母線接続および点検作業用の開口を設け、取り外し式のカバー17を取り付け、母線接続および点検作業は、盤正面から前記カバー17を取り外して行う。
本実施例は、「2フィーダ、1母線の2段積」の例であるが、「2フィーダ、2母線の2段積」、あるいは「3フィーダ、1母線の3段積」にも適用することができる。
【0006】
【発明の効果】
以上述べたように、本発明によれば、次のような効果がある。
(1) 母線室を、上下各遮断器室の中間位置に配置するとともに、上側遮断器室の下面側にガイシ取付板を配置し、前記ガイシ取付板の下面に、2個の母線固定ガイシをそれぞれ垂直方向に向けて配置し、かつ、下側遮断器室の上面側に、1個の母線固定ガイシを、垂直方向に向けて配置し、さらに、前記1個の母線固定ガイシを、前記上側の2個の固定ガイシの下方に、空間を介して配置して、前記母線室内に収納した母線の相配置を、逆三角形状にしているので、従来の配電盤で母線7と作業者の間に介在していた「母線固定ガイシ14および取り付け板15」、「外部端子9b」、および「ケーブル10a,10b」などの障害物が無くなり、母線接続および点検作業の作業性が向上する。
(2)遮断器の上下間の余ったスペースに母線室を配置したことで従来の母線室スペースが不要になり、盤高さ寸法に影響することなく盤寸法(奥行き方向)を縮小することができる。
