この発明は、引出形しや断器における制御線引
き渡し部の制御プラグ装置に係り、さらにいえ
ば、制御プラグが不意に外れることを防ぐインタ
ーロツク装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control plug device for a control line delivery section in a drawer type or disconnector, and more particularly to an interlock device that prevents a control plug from accidentally coming off.
この発明の主目的は、引出形しや断器の移動中
あるいは主回路接続中は、しや断器が接続位置又
は接続位置と断路位置との間に在るかぎり、制御
プラグが外れぬようロツクするインターロツク装
置を提供することにある。つまり制御プラグが外
れると、しや断器への命令が断たれ、動作しなく
なるからである。 The main purpose of this invention is to prevent the control plug from coming off while the drawer or disconnector is being moved or connected to the main circuit, as long as the drawer or disconnector is in the connecting position or between the connecting position and the disconnecting position. An object of the present invention is to provide an interlock device that locks the lock. In other words, if the control plug is removed, the command to the breaker will be cut off and it will no longer operate.
この発明の次の目的は、制御プラグは断路位置
でのみ抜き外すことができ、この位置で抜き外さ
れぬかぎりしや断器を接続位置に押し入れること
又は逆に断路位置からしや断器を引き出すことも
できないようにロツクするインターロツク装置を
提供することにある。メンテナンス等の必要のた
め断路位置よりさらに引き出すときは、危険防止
のため遠方からの命令を断つ必要があり、また、
制御ケーブルを引つ張つて傷めてしまう虞れもあ
るためである。 A further object of the invention is that the control plug can only be removed in the disconnected position, and that unless it is removed in this position, it is possible to force the disconnector into the connected position or, conversely, to force the disconnector into the connected position from the disconnected position. An object of the present invention is to provide an interlock device that locks the device so that it cannot be pulled out. When pulling out further than the disconnected position due to maintenance, etc., it is necessary to cut off commands from a distance to prevent danger.
This is because there is a risk that the control cable may be pulled and damaged.
一方、制御プラグを挿し込むのを忘れてしや断
器を主回路接続位置に移動した場合には、制御プ
ラグを挿し込み不可能で、そのままではしや断器
の動作も不能であり、断路位置で制御プラグを挿
し込まないかぎり接続位置へ移動不能となるよう
にロツクする必要があるためである。 On the other hand, if you forget to insert the control plug and move the cutter to the main circuit connection position, you will not be able to insert the control plug, and the cutter or cutter will not be able to operate as it is, and the disconnector will be disconnected. This is because it needs to be locked so that it cannot be moved to the connection position unless the control plug is inserted at that position.

The plugs 5a, 5b, and 5c are connected separately. The three plugs 5a, 5b, and 5c are attached and fixed together in a common plug cover case 6, and the female plugs 8a, 8b, and 8c are fixed and installed on the side surface of the pedestal 11 with a support frame 7. It is configured to be detachable. 9 in FIG. 7 is a plug pin. Support bolts 14, 14 are installed above and below the support frame 7.
On the other hand, bolt holes 18 are provided at the top and bottom of the plug cover case 6, through which the support bolts 14, 14 are passed, and the plug cover case 6 is tightened and attached with a nut 19. Plug cover case 6

状態となる構成としている。 As is clear from FIGS. 3 and 7, two operating rods 26 and 27 are vertically installed at the lower side of the pedestal 11 so that they can be raised and lowered by a support frame 28. A coil spring 29 whose lower end is supported by a support frame 28 is wound around the operating rod 26, and its upper end is received by a spring receiver 30 fixed to the operating rod 26, so that an upward spring force is applied to the operating rod 26. I try to do that. A coil spring 31 whose upper end is supported by a support frame 28 is wound around the other operating rod 27, and its lower end is received by a spring receiver 32 fixed to the operating rod 27.
7 is applied with an upward spring force. Pin-shaped engagers 26a and 27a are attached to the upper ends of the two operating rods 26 and 27 and protrude at approximately right angles, and when the plug cover case 6 is installed in the plug pushing position, the engagers 26a are attached to the engaging portions. 22
Furthermore, the engaging members 27a are respectively engaged with the engaging portions 23, and the operating rod 27 is configured to be able to enter and exit from the lock hole 25 of the lock plate 24 from below.

When the plug is installed in the plug-in position as shown in the figure, the engaging part 22 engages with the engaging element 26a, compressing the coil spring 29 and pushing down the operating rod 26 to a predetermined position, and conversely, the engaging part 23 engages with the engaging element 26a. engages with the gouger 27a,
The coil spring 31 is compressed to push up the operating rod 27 to a predetermined height. However, at this stage, the upper end of the operating rod 27 has not yet entered the locking hole 25 (FIG. 9).

More specifically, as shown in FIG. 5, two lock rods 40, 41 are supported by upper and lower plates 42a, 42b of a support frame 42 fixed to the side surface of the pedestal 11 so as to be movable up and down. A crank 4 is rotatably installed around a shaft 43 of the same support frame 42.
The ends of the link rods 38, 39 are connected to one ends of the links 4, 45. Further, the other ends of the cranks 44, 45 are connected to the lock rods 40, 41, so that the lock rods 40, 41 and the operating rods 26, 27 are moved up and down in conjunction with each other.

Each movement locus line 46 of the two locking rods 40, 41 in the loading/unloading direction along the rail 17,
47, in particular, on the movement trajectory line 46, when the drawer or disconnector 1 is in the disconnection position (Fig. 3), the lower end of the locking rod 40 that is to be pulled out further collides with the side ( A relatively short block-shaped stopper 4 with a constant height h1 is placed on the drawer side).
8 is installed in a fixed manner.

A rail-shaped cam 49 having a length spanning the entire length in the connection direction is fixed and installed. An inclined surface 49 is formed at the starting end of the cam 49. In other words, only when the drawer or disconnector 1 is in the disconnection position, the 2
The book locking rods 40, 41 are free from both the stopper 48 and the cam 49.

高さまで上昇する。 Therefore, when the plug cover case 6 is attached to the plug insertion position when the drawer or disconnector 1 is in the disconnection position, the engaging portion 22 is connected to the operating rod 26 via the engaging element 26a, as shown in FIG. As a result of pushing down the locking rod 40 by a certain stroke, the locking rod 40 descends and its lower end collides with the stopper 48, so that the drawer or disconnector 1 cannot be pulled out any further.
On the other hand, as a result of the engaging portion 23 pulling up the operating rod 27 by a certain stroke via the engaging element 27a, the locking rod 41 rises to a height where its lower end touches the inclined surface 49a of the cam 49.

とはできない。 Therefore, when the drawer or the disconnector 1 is moved in the connection direction, the lower end of the locking rod 41 becomes the inclined surface 49.
further pushed up along a, and the cam 49
is held at a height h 2 above the top surface of the Then, the operating rod 27 is further raised via the link rod 39, and the eighth
As shown in the figure, the upper end of the operating rod 27 enters into the locking hole 25 of the locking plate 24. Therefore, the plugs 5a to 5c and the plug cover case 6
are locked and can no longer be removed.

となる。 However, if the plugs 5a to 5c are pulled out through the plug cover case 6 when the drawer or disconnector 1 is in the disconnection position (FIG. 3), the engaging portion 2
2 is released, the operating rod 26 is raised greatly by the coil spring 29, and the lower end of the locking rod 40 is moved to the stopper 48.
rise until higher. Therefore, the drawer mold and disconnector 1 can be further pulled out from the disconnection position.
なお、一旦引き出したしや断器は、再び断路位
置まで戻してからでなければ、プラグ及びプラグ
カバーケースを装着できない。ロツク棒４０がス
トツパ４８に衝突し戻れなくなるからである。 Note that once the disconnector has been pulled out, the plug and plug cover case cannot be attached until it is returned to the disconnection position. This is because the lock rod 40 collides with the stopper 48 and cannot return.
