Description
保守点検等で開閉器2が主回路断路部5から切り離されて固定枠1の前面側に引き出され、図5のような引出位置にあるときは、シャッタ板6はシャッタ保持フレーム7と共に下降し、主回路断路部5の絶縁筒5aの前面を塞ぎ通電部である中心導体5bが露出しないように閉鎖されている。レバー13の下部側はガイド溝11の前方端にスライドして図のような位置にある。
図5のような状態から、開閉器2を接続状態にするときは、開閉器2を車輪ガイド9に沿って後方へ押し込む。これにより、先ず、開閉器2の後部が移動ピン12と一体に形成された当接部12aに当接して係合し、接続動作に入る開閉器2の位置が検出される。この状態で更に後方(奥)へ押し込むと、開閉器2の後部で当接部12aが押されることで、レバー13の下部側がガイド溝11に沿って後方に移動する。レバー13の上部側がシャッタ保持フレーム7にピン14で回動自在に連結されているので、それに連動してシャッタ保持フレーム7と共にシャッタ板6が上昇する。
Maintenance switch 2 at the inspection or the like is drawn on the front side of the fixed frame 1 is disconnected from the main circuit disconnector 5, when Ru near such extracted position shown in FIG. 5, the shutter plate 6 is lowered along with the shutter holding frame 7 Then, the front surface of the insulating cylinder 5a of the main circuit disconnecting portion 5 is closed so that the central conductor 5b as the energizing portion is not exposed. The lower side of the lever 13 slides to the front end of the guide groove 11 and is at the position shown in the figure.
When the switch 2 is brought into the connected state from the state as shown in FIG. 5, the switch 2 is pushed rearward along the wheel guide 9. Thereby, first, the rear part of the switch 2 is brought into contact with and engaged with the contact part 12a formed integrally with the moving pin 12, and the position of the switch 2 entering the connection operation is detected. In this state, when pushing further backward (backward), the lower part of the lever 13 moves rearward along the guide groove 11 by pushing the contact part 12 a at the rear part of the switch 2. Since the upper side of the lever 13 is rotatably connected to the shutter holding frame 7 by the pin 14, the shutter plate 6 rises together with the shutter holding frame 7 in conjunction therewith.
更に、ガイド溝は、前方側から後方側に向かう途中までが水平で、途中から下方に円弧状に曲げられて形成されており、開閉器が引出位置と接続位置との間を移動する過程で、開閉器の上部及び下部端子の先端部がシャッタ板の開閉面の位置から接続位置までの移動区間では、シャッタ板が開放状態を保ってほぼ静止するように構成されているので、シャッタ板の移動を少なくでき、固定枠の小型化を図ることができる。 Further, the guide groove is formed in a horizontal direction from the front side to the rear side and is bent in a circular arc shape from the middle to the lower side. In the process in which the switch moves between the drawing position and the connection position. In the movement section from the position of the opening / closing surface of the shutter plate to the connection position, the shutter plate is configured to remain almost open and remain stationary in the moving section from the position of the opening / closing surface of the shutter plate to the connection position. move-out a small Kude, it is possible to reduce the size of the fixed frame.
Claims (1)
