A drawer device 6 moves and operates the circuit breaker 3 to the operation / test position, and an interlock mechanism 6 locks the panel door 1a of the closing panel 1 to the closed position at the operation position of the circuit breaker 3.

ここで、回路遮断器３は車輪３ｂ付きの台車３ａを備え、クレードル２のの左右側縁に形成したガイドレール２ａに沿って前後移動可能に搭載されている。また、引出装置５は、図６で示すように回路遮断器３の移動経路に沿ってクレードル２の底部に敷設したねじシャフト５ｂの移動ナット５ｃに前記台車３ａの底部に取付けたラッチ５ａを掛止し、盤外から挿入したハンドル７を前記シャフト６ｂに連結してハンドル操作することにより、移動ナット５ｃ，ラッチ５ａを介して回路遮断器３を運転位置／試験位置（図３参照）に移動するようにしている。なお、５ａ−１はラッチ５ａの掛止／釈放用ハンドルである。   Here, the circuit breaker 3 includes a carriage 3a with wheels 3b, and is mounted so as to be movable back and forth along guide rails 2a formed on the left and right side edges of the cradle 2. Further, as shown in FIG. 6, the drawing device 5 has a latch 5a attached to the bottom of the carriage 3a on a moving nut 5c of a screw shaft 5b laid on the bottom of the cradle 2 along the moving path of the circuit breaker 3. The circuit breaker 3 is moved to the operating position / test position (see FIG. 3) via the moving nut 5c and the latch 5a by operating the handle by connecting the handle 7 inserted from the outside of the panel to the shaft 6b. Like to do. Reference numeral 5a-1 denotes a latch / release handle for the latch 5a.

一方、インターロック機構６は、図４で示すようにクレードル２の外側面に配置して回路遮断器３と盤扉１ａとを連係し、その構造は取付基台に支軸６ｃを介して枢支したシーソー式レバー６ａと、該レバー６ａのレバー後部に対向して台車３ａの側面に取付けたローラ形のドグ６ｂと、シーソー式レバー６ａの先端に形成したＬ字形のフック部６ｄと、シーソー式レバー６ａのレバー後部の上縁をドグ６ｂに押し当てるよう付勢する付勢ばね６ｅとからなり、前記フック部６ｄを盤とａの裏面に設けた掛け金８に対峙させている。   On the other hand, the interlock mechanism 6 is arranged on the outer surface of the cradle 2 as shown in FIG. 4 to link the circuit breaker 3 and the panel door 1a, and its structure is pivoted to the mounting base via the support shaft 6c. A supported seesaw lever 6a, a roller-shaped dog 6b mounted on the side surface of the carriage 3a so as to face the rear part of the lever 6a, an L-shaped hook portion 6d formed at the tip of the seesaw lever 6a, and a seesaw The lever 6a includes a biasing spring 6e that biases the upper edge of the rear portion of the lever against the dog 6b. The hook 6d is opposed to a latch 8 provided on the back of the board and a.

前記構成で、回路遮断器３を試験位置に引き出した状態では、図７（ａ），（ｂ）で示すように、インターロック機構６のシーソー式レバー６ａが図示位置に回動し、その先端のフック部６ｄが掛け金８から下方に抜け出している。これにより、盤扉１ａはインターロック機構の拘束を受けずに自由に開放できる。これに対して、閉鎖盤１の盤扉１ａを閉じた上で回路遮断器３を運転位置に押し込み移動すると、図８（ａ），（ｂ）で表すようにシーソー式レバー６ａのレバー後部がドグ６ｂに押し下げられて時計方向に回動し、先端フック部６ｄが盤扉１ａに設けた掛け金８の裏側に進入して係合する。これにより、盤扉１ａは閉位置に鎖錠されることになる。

ところで、前記した従来構造のスイッチギアでは次記のような問題点がある。すなわち、インターロック機構６を構成するシーソー式レバー６ａ，ドグ６ｂなどの部品をクレードル２の外側側に配置して回路遮断器３の台車３ａと盤扉１ａの裏面に設けた掛け金８との間を連係するようにしている。
このために、閉鎖盤１の遮断器室側壁とクレードル２との間に確保する間隔ｄ（図４参照）が大きくなり、盤内のスペース効率が低下して閉鎖盤１が大形化する。また、回路遮断器の搬入，搬出時に延長レールをクレードル２の前端に敷設し、回路遮断器３を盤内のクレードル２に対して搬入，搬出する場合に、クレードル２のガイドレール２ａに対し、その前部側面に配置したインターロック機構６が邪魔になって延長レールの敷設作業が困難となる問題もある。 However, the above-described conventional switchgear has the following problems. That is, the parts such as the seesaw type lever 6a and the dog 6b constituting the interlock mechanism 6 are arranged on the outer side of the cradle 2 and between the carriage 3a of the circuit breaker 3 and the latch 8 provided on the back surface of the panel door 1a. Are trying to work together.
For this reason, the space | interval d (refer FIG. 4) ensured between the circuit breaker chamber side wall of the closure board 1 and the cradle 2 becomes large, the space efficiency in a board falls, and the closure board 1 enlarges. Further, when the circuit breaker is carried in and out, an extension rail is laid on the front end of the cradle 2, and when the circuit breaker 3 is carried in and out of the cradle 2 in the panel, the guide rail 2a of the cradle 2 is There is also a problem that it is difficult to lay the extension rail because the interlock mechanism 6 arranged on the front side surface becomes an obstacle.

本発明は上記の点に鑑みなされたものであり、その目的は閉鎖盤に収納した回路遮断器と盤扉とを連係するインターロック機構の構成，配置を改良し、盤内のスペース効率を高めて閉鎖盤をコンパクトに構成するようにし、また回路遮断器を搬入，搬出する際に使用する延長レールの敷設作業が楽に行えるようにしたスイッチギアを提供することにある。   The present invention has been made in view of the above points, and its purpose is to improve the structure and arrangement of an interlock mechanism that links a circuit breaker housed in a closed panel and a panel door, thereby increasing the space efficiency in the panel. The present invention is to provide a switchgear in which the closing board is configured in a compact manner, and the extension rail used to carry in and out the circuit breaker can be easily laid.

上記目的を達成するために、本発明によれば、閉鎖盤の盤内に構築したクレードルに引出形の高圧回路遮断器を搭載し、かつ回路遮断器を運転,試験位置へ移動操作する引出装置、および回路遮断器の運転位置で閉鎖盤の盤扉を閉位置に鎖錠するインターロック機構を備えたスイッチギアにおいて、
前記インターロック機構を引出装置の側方に並置してクレードルの底部中央寄りに配備し、この位置で回路遮断器の台車と盤扉の裏面に設けたロック掛け金との間を連係させものとし（請求項１）、具体的にはインターロック機構を次記のような態様で構成する。
（１）前記インターロック機構は、回路遮断器の台車移動方向に沿ってクレードルの底部に布設し、かつレール前端のフック部を盤扉のロック掛け金に対向させたシーソー式レバーと、該シーソー式レバーのレバー後部を回路遮断器の台車底部側に取付けたローラ形ドグに押し当てるように付勢する付勢ばねとからなり、回路遮断器の運転位置で前記シーソー式レバーのフック部を前記掛け金に係合して盤扉を閉位置に鎖錠させるようにする（請求項２）。
（２）前項（１）において、シーソー式レバーを水平方向へ揺動可能に枢支した上で、そのレバー後部がローラ形ドグの移動経路に対し斜め方向から鎖交するように布設する（請求項３）。 In order to achieve the above-described object, according to the present invention, a drawer type high-voltage circuit breaker is mounted on a cradle constructed in a closed board, and the circuit breaker is operated and moved to a test position. In a switchgear having an interlock mechanism that locks the panel door of the closing board to the closed position in the operation position of the circuit breaker,
The interlock mechanism is juxtaposed to the side of the drawer and is arranged near the center of the bottom of the cradle, and at this position, the circuit breaker carriage and the lock latch provided on the back of the panel door are linked ( Claim 1), specifically, the interlock mechanism is configured in the following manner.
(1) The interlock mechanism includes a seesaw-type lever that is laid on the bottom of the cradle along the carriage moving direction of the circuit breaker and the hook portion at the front end of the rail faces the lock latch of the panel door, and the seesaw type It consists of a biasing spring that biases the lever rear part against the roller-type dog attached to the bottom of the circuit breaker carriage. The hook of the seesaw lever is latched at the circuit breaker operating position. And the panel door is locked in the closed position (claim 2).
(2) In the preceding paragraph (1), the seesaw type lever is pivotally supported so as to be swingable in the horizontal direction, and the rear part of the lever is laid so as to be linked obliquely with respect to the moving path of the roller type dog. Item 3).

上記の構成によれば、インターロック機構の構成部品は回路遮断器の引出装置と並置してクレードルの底部に配置されていて、クレードルの外側面にはインターロック機構の部品が突き出すことがない。したがって、従来構造と比べて閉鎖盤の遮断器室側壁とクレードルとの間に確保する間隔を縮減して閉鎖盤の小形，コンパクト化が図れるほか、回路遮断器の搬入，搬出の際には延長レールをインターロック機構との干渉のおそれなしに閉鎖盤の前方からクレードルの左右に敷設して使用することができる。   According to said structure, the component of an interlock mechanism is arrange | positioned in parallel with the drawer | drawing-out apparatus of a circuit breaker, and is arrange | positioned at the bottom part of the cradle, and the part of an interlock mechanism does not protrude to the outer surface of a cradle. Therefore, compared with the conventional structure, the space secured between the circuit breaker chamber side wall and the cradle of the closing board can be reduced to reduce the size and size of the closing board, and it can be extended when loading and unloading circuit breakers. The rails can be used by laying on the left and right sides of the cradle from the front of the closing board without the possibility of interference with the interlock mechanism.

しかも、シーソー式レバーを水平方向へ揺動可能に配置したことで、クレードルの底部と回路遮断器の台車との間の高さ方向の間隔も縮減できる。   In addition, since the seesaw type lever is disposed so as to be swingable in the horizontal direction, the distance in the height direction between the bottom of the cradle and the carriage of the circuit breaker can be reduced.

以下、本発明の実施の形態を図１，図２に示す実施例に基づいて説明する。なお、実施例の図中で図３〜図８に対応する部材には同じ符号を付してその説明は省略する。
図１（ａ）〜（ｃ）および図２（ａ）〜（ｃ）において、回路遮断器３の運転位置で閉鎖盤１の盤扉１ａを閉位置に鎖錠するインターロック機構６は、図６で述べた回路遮断器３の引出装置５の側方に並置してクレードル２の底部中央側に配置されている。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below based on the examples shown in FIGS. In addition, in the figure of an Example, the same code | symbol is attached | subjected to the member corresponding to FIGS. 3-8, and the description is abbreviate | omitted.
1 (a) to 1 (c) and FIGS. 2 (a) to 2 (c), an interlock mechanism 6 that locks the panel door 1a of the closing panel 1 in the operating position of the circuit breaker 3 is shown in FIG. The circuit breaker 3 described in FIG. 6 is disposed in parallel to the side of the drawing device 5 and is arranged on the bottom center side of the cradle 2.

ここで、インターロック機構６の構造は、回路遮断器３の移動方向に沿って布設したシーソー式レバー６ａの支軸６ｃを縦軸としてレバーが水平に揺動可能に配備した上で、その支軸６ｃから後方に延在するレバー後部が引出装置５の移動ナット５ｃに取付けたローラ形ドグ６ｂの移動経路に対して斜めに鎖交するように配置し、かつ付勢ばね６ｅで後部レバーをドグ６ｂに向けて押し当てるようにしている。また、シーソー式レバー６ａの先端にはＬ字形のフック部６ｄを上向きに起立形成し、盤扉１ａの裏面に取付けた掛け金８に対して側方から回動して係合するようにしている。   Here, the structure of the interlock mechanism 6 is such that the lever is provided so that the lever can swing horizontally with the support shaft 6c of the seesaw type lever 6a installed along the moving direction of the circuit breaker 3 as the vertical axis. The rear part of the lever extending rearward from the shaft 6c is arranged so as to be obliquely linked to the moving path of the roller-shaped dog 6b attached to the moving nut 5c of the drawing device 5, and the rear lever is moved by the biasing spring 6e. It pushes toward the dog 6b. Further, an L-shaped hook portion 6d is erected upward at the tip of the seesaw type lever 6a so as to rotate and engage with a latch 8 attached to the back surface of the panel door 1a. .

上記構成になるインターロック機構６の機能，動作は、図７，図８で述べた従来構造と同様であり、図１（ａ）〜（ｃ）で示すように引出装置５のハンドル操作で回路遮断器３を試験位置に引出し移動すると、ドグ６ｂの移動に従動してシーソー式レバー６ａが時計方向に回動し、レバー先端のフック部６ｄが掛け金８から側方に抜け出る。これにより、盤扉１ａはインターロック機構６の拘束を受けずに自由に開閉できる。   The functions and operations of the interlock mechanism 6 having the above-described configuration are the same as those of the conventional structure described with reference to FIGS. 7 and 8, and the circuit is operated by operating the handle of the drawer 5 as shown in FIGS. When the circuit breaker 3 is pulled out and moved to the test position, the seesaw lever 6a is rotated in the clockwise direction following the movement of the dog 6b, and the hook portion 6d at the end of the lever is pulled out from the latch 8 to the side. Thereby, the panel door 1a can be freely opened and closed without being restricted by the interlock mechanism 6.

一方、盤扉１ａを閉じた上で、図２（ａ）〜（ｃ）で示すように回路遮断器３を試験位置から運転位置に移動すると、ローラ形ドグ６ｂに押されてシーソー式レバー６ａが支軸６ｃを支点に反時計方向に回動し、レバー先端のフック部６ｄが側方から盤扉１ａに設けた掛け金８の裏側に進入して係合する。これにより、盤扉１ａは閉位置に鎖錠されて開放することができなくなる。   On the other hand, when the circuit breaker 3 is moved from the test position to the operation position as shown in FIGS. 2A to 2C after the panel door 1a is closed, the seesaw lever 6a is pushed by the roller dog 6b. Rotates counterclockwise about the support shaft 6c, and the hook portion 6d at the end of the lever enters the rear side of the latch 8 provided on the panel door 1a from the side and engages. Thereby, the panel door 1a is locked in the closed position and cannot be opened.
