Description

この発明に係る配電盤のシャッタ装置は、前後方向に移動自在な引出形の開閉器が収容される固定枠と、固定枠の後壁に設けられて開閉器の後部から導出した上部端子及び下部端子と接離可能な主回路断路部と、主回路断路部の前方にあって固定枠内を開閉器室と主回路断路部室とに仕切ると共に開閉器の上部端子及び下部端子の各端子が貫通可能な貫通窓を有する絶縁バリヤと、絶縁バリヤの主回路断路部室側にあって上下動により貫通窓を開放又は閉鎖するシャッタと、開閉器が、主回路断路部から切り離されて前方に引き出された引出位置と主回路断路部に接続された接続位置との間を移動する移動動作に連動し、引出位置ではシャッタを閉鎖し、接続位置では開放するシャッタ駆動機構と、を備え、主回路断路部は主回路断路部室内に開放配置されたものである。 A shutter device for a switchboard according to the present invention includes a fixed frame that houses a drawer-type switch that is movable in the front-rear direction, and an upper terminal and a lower terminal that are provided on the rear wall of the fixed frame and are led out from the rear of the switch The main circuit disconnection part that can be connected to and separated from the main circuit disconnection part, and in front of the main circuit disconnection part, the fixed frame is partitioned into the switch room and the main circuit disconnection part room, and each terminal of the upper and lower terminals of the switch can penetrate an insulating barrier having a Do through window, a shutter for opening or closing the through-window by vertical movement be in the main circuit disconnector chamber side of the isolation barrier, switch is pulled forwardly detached from the main circuit disconnector linked to the moving operation of moving between the connected connection position to the drawn-out position and the main circuit disconnector, closing the shutter in the pull-out position, and a shutter drive mechanism to open a connection position, the main circuit disconnector Is inside the main circuit disconnection section Those which are open configuration.

この発明の配電盤のシャッタ装置によれば、引出形の開閉器が収容され、後壁に主回路断路部を有する固定枠内を、絶縁バリヤにより開閉器室と主回路断路部室とに仕切ると共に、絶縁バリヤに開閉器の上部端子及び下部端子が貫通可能な貫通窓を形成し、絶縁バリヤの主回路断路部室側に貫通窓を開放又は閉鎖するように上下動するシャッタを設け、開閉器が引出位置と接続位置との間を移動する移動動作に連動し、引出位置ではシャッタを閉鎖し、接続位置では開放するシャッタ駆動機構を備え、主回路断路部は主回路断路部室内に開放配置されているので、主回路断路部室の広い空間により主回路断路部の放熱性が向上し、また、シャッタの動作ストロークを小さくできるため、主回路断路部室の小形化が可能となり、配電盤の小形化を図ることができる。
更に、絶縁バリヤの後方、すなわち主回路断路部室側にシャッタを配置して、貫通窓を小さくできるため、異物の挿入が阻止され、配電盤内の点検・保守時等にシャッタに触れることを防止し、不用意なシャッタ開放を防いで操作員の感電を防止できる。 According to the shutter device of the switchboard of the present invention, the drawer-type switch is housed, and the inside of the fixed frame having the main circuit disconnection part on the rear wall is partitioned into the switcher room and the main circuit disconnection part chamber by the insulating barrier, upper terminal and lower terminal of the switch to the isolation barrier forms a possible penetration windows through, provided the shutter moves up and down to open or close the through-window in the main circuit disconnector chamber side of the isolation barrier, switch the In conjunction with the movement of moving between the pull-out position and the connection position, it has a shutter drive mechanism that closes the shutter at the pull-out position and opens at the connection position, and the main circuit disconnection section is arranged open in the main circuit disconnection section chamber. Therefore, the large space of the main circuit disconnection part room improves the heat dissipation of the main circuit disconnection part, and the operating stroke of the shutter can be reduced, so the main circuit disconnection part room can be downsized and the switchboard can be downsized. It is possible to achieve.
In addition, a shutter can be placed behind the insulation barrier, that is, on the main circuit disconnection part chamber side to reduce the size of the through window, preventing foreign matter from being inserted and preventing the shutter from being touched during inspection and maintenance in the switchboard. In addition, it is possible to prevent an operator from receiving an electric shock by preventing inadvertent shutter opening.
