本発明は、 ばねを蓄勢してそのエネルギーにより断路器などの開閉器の 可動部を駆動する開閉器用ばね操作器に関する。 背景技術 . 断路器などの開閉器の入 ·切操作を行うためにばね操作器が使用されて いる。  The present invention relates to a spring operating device for a switch that stores a spring and drives a movable portion of a switch such as a disconnector with the energy of the spring. BACKGROUND ART A spring operating device is used to turn on / off a switch such as a disconnector.
図 4は従来の開閉器用ばね操作器の斜視図である。 開閉器用ばね操作器 は、 出力軸に取付けた連結レバ一に連結した操作ロッドを介して断路器の 入 ·切操作をするものである。  FIG. 4 is a perspective view of a conventional spring operating device for a switch. The spring actuator for the switch is used to turn on / off the disconnector via an operating rod connected to a connecting lever attached to the output shaft.
図 4において、 ギヤ一ドモータ 1の回転カをギヤードモー夕 1の出力軸 に直結したウォーム軸 2と対をなすウォームホイ一ル 4で減速して、 ゥォ —ムホイール 4に係合段部 4 a， 5 aで係合されたトグルレバー 5を回転 させる。 なお、 ギヤードモー夕 1に代えて手動操作ハンドル 2 cを傘歯車 2 bの操作軸 2 dに連結して回転させることもできる。  In FIG. 4, the rotating power of the geared motor 1 is decelerated by the worm wheel 4 paired with the worm shaft 2 directly connected to the output shaft of the geared motor 1, and the stepped portion 4 a, 5 Turn the toggle lever 5 engaged in a. Instead of the geared motor 1, the manual operation handle 2c can be connected to the operation shaft 2d of the bevel gear 2b and rotated.
トグルレバー 5の回転によって、 一端が固定され他端がトグルレバー 5 に連結されているトグルばね 8を圧縮する。 トグルレバー 5とトグルばね 8がー直線になつて死点を形成したときにトダルばね 8は最大に圧縮され、 さらに卜ダルレバ一 5が回転してトダルばね 8の死点を超えた直後に放勢 されて、 トグルレバー 8はクイック動作する。 この時トグルレバー 5は、 ウォームホイール 4との係合が解け、 トグルばね 8の放勢力によってトグ ルレバ一 5を駆動し、 さらにトグルレバー 5の係合段部 5 bとレバ一 9の 係合段部 9 aの係合により駆動されたレバ一 9は、 レバー 9に設けたロー ラ 1 0と係合するフォーク状のハサミレバー 1 2を介して出力軸 1 1を駆 動し、 出力軸 1 1の連結レバ一 1 3に連結した操作ロッド 1 5を介して断 路器 1 4の入 ·切操作をする。 The rotation of the toggle lever 5 compresses a toggle spring 8 having one end fixed and the other end connected to the toggle lever 5. When the toggle lever 5 and the toggle spring 8 are in a straight line to form a dead center, the todal spring 8 is compressed to the maximum, and is released immediately after the todal lever 1 rotates and exceeds the dead center of the todal spring 8. When activated, the toggle lever 8 operates quickly. At this time, the toggle lever 5 is disengaged from the worm wheel 4 and drives the toggle lever 5 by the biasing force of the toggle spring 8, and furthermore, the engagement step 5b of the toggle lever 5 and the lever 9 are engaged. The lever 9 driven by the engagement of the step portion 9a drives the output shaft 11 through a fork-shaped scissor lever 12 that engages with the roller 10 provided on the lever 9, and the output shaft 11 11 Disconnect via the operating rod 15 connected to the connecting lever 13 Turn on / off the road device 14.
図 5は従来のばね操作器の負荷トルクと操作器の出力トルク特性を示す 図である。 従来のばね操作器は、 出力軸の動き始めである死点ではトグル ばねの荷重は大きいがトグルレバーのモーメントアームが小さく、 また出 力軸の動き終わりではトグルレバーのモーメントアームは大きいがトグル ばねの荷重は小さくなるため、 トグルレバーのトルクは動作の途中にピー クを有する山形特性となる。  FIG. 5 is a diagram showing load torque of a conventional spring operating device and output torque characteristics of the operating device. In the conventional spring actuator, the load of the toggle spring is large at the dead point where the output shaft starts to move, but the moment arm of the toggle lever is small at the end of the output shaft movement. Since the load on the lever becomes smaller, the torque of the toggle lever has a mountain-shaped characteristic with a peak during the operation.
一方、 ばね操作器が適用される開閉器の負荷特性は、 行程初期または行 程終期に大きなトルクを必要とするため、 前記ハサミレバーによって動作 の途中にポトムを有するバスタブ形特性に変換している。  On the other hand, the load characteristic of the switch to which the spring operating device is applied requires a large torque at the beginning of the stroke or at the end of the stroke, and is converted into a bathtub type characteristic having a potom in the middle of operation by the scissor lever. .
開閉器の負荷特性は図 5に示すように入と切で全く異なる。 一方、 ハサ ミレバーによって変換されるトルク特性は入と切りで等しい特性とならざ るをえず、 行程初期と行程終期で過大なトルクが発生し、 次に示す課題が ある。  As shown in Fig. 5, the load characteristics of the switch are completely different between on and off. On the other hand, the torque characteristics converted by the scissor lever must be the same for the on and off states, and excessive torque is generated at the beginning and end of the stroke, causing the following problems.
( 1 ) 無駄なエネルギーを放出するので必要以上のばね荷重となり、 操作 器の寸法が大きくなる。  (1) Unnecessary energy is released, resulting in an excessive spring load and an increase in the size of the actuator.
( 2 ) 行程終期で過大なトルクが発生するので、 緩衝装置が大型となる。 (2) Since excessive torque is generated at the end of the stroke, the shock absorber becomes large.
( 3 ) ハサミレバー部分の滑り摩擦によるロスが大きい。 発明の開示 (3) The loss due to sliding friction of the scissor lever is large. Disclosure of the invention
そこで、 本発明は、 出力トルク特性を任意に設定可能とし、 負荷に応じ たトルク特性が実現できる開閉器用ばね操作器を提供するものである。 本発明は、 回転可能なトグルレバーにトグルばねが連結され、 トグルレ パーが回転してトグルレバーとトグルばねが死点を形成し、 さらにトグル レバーが回転して前記死点を超えた直後にトグルレバーがクイック動作し、 トダルレバ一により駆動された出力軸の回転により開閉器の入 ·切操作を する開閉器用ばね操作器において、 トグルレバーとトグルばねの間に中継 軸とリンクを設け、 中継軸のレバ一角度の設定により出力トルク特性を任 意に設定して、 負荷に応じたトルク特性が実現できる。 回転方向によって異なる出力軸トルク特性を備え、 一方の回転方向では 回転初期が回転終期より大きく、 他方の回転方向では回転初期が回転終期 より小さい出力軸トルク特性を備えることができる。 図面の簡単な説明 Therefore, the present invention provides a spring operating device for a switch, which can arbitrarily set an output torque characteristic and can realize a torque characteristic according to a load.

On the worm wheel side of the toggle lever 5, there is formed an engagement step 5a that engages with the engagement step 4a of the worm wheel 4. The engagement of the engagement steps 4a, 5a of the two causes the toggle lever 5 to engage. Rotate 5
トダルレバー 5にはリンク 6の一端が枢着され、 リンク 6の他端は軸 7 aに軸支された中継レバ一 7の一端に枢着されている。 中継レバー 7の他 端は、 一端が固定されたトグルばね 8の他端に枢着されている。 トグルレ パー 5の回転により、 リンク 6を介して中継レバ一 7が回転してトグルば ね 8を圧縮する。 One end of a link 6 is pivotally connected to the todal lever 5, and the other end of the link 6 is a shaft 7 It is pivotally attached to one end of a relay lever 7 supported by a. The other end of the relay lever 7 is pivotally connected to the other end of a toggle spring 8 having one end fixed. The rotation of the toggle lever 5 rotates the relay lever 7 via the link 6 to compress the toggle spring 8.
トグルレバー 5に隣接して連結レバー 1 3が回転自在に配置され、 連結 レバー 1 3のトグルレバ一側にはトグルレバ一 5の係合段部 5 bと係合す る係合段部 1 3 aが形成され、 両者の係合段部 5 b , 1 3 aの係合により トグルレバー 5がレバー 1 3を回転させる。 トグルレバー 5の係合段部 5 bと連結レバー 1 3の係合段部 1 3 aは、 圧縮されたトダルばね 8が死点 を形成したときに係合するように形成する。 連結レバ一 1 3には断路器 1 4の操作ロッド 1 5が連結される。  The connecting lever 13 is rotatably arranged adjacent to the toggle lever 5, and the engaging lever 13 of the connecting lever 13 is engaged with the engaging step 5b of the toggle lever 5 on one side of the toggle lever.

次に本発明のばね操作器の動作について説明する。 図 2 ( a ) 〜 （c ) はトグルレバーとトダルばねが変化する状態を示す図である。  Next, the operation of the spring operating device of the present invention will be described. FIGS. 2A to 2C are diagrams showing a state in which the toggle lever and the todal spring change.
切りの状態から、 ギヤ一ドモ一夕 1または手動ハンドル 2 cによりゥォ ーム軸 2が回転すると、 ウォームホイール 4が回転し、 ウォームホイール 4の係合段部 4 aとトグルレバー 5の係合段部 5 aの係合によりトグルレ バー 5を時計方向に回転させる。  When the gear shaft 2 is rotated by the gear 1 or the handwheel 2c from the disengaged state, the worm wheel 4 is rotated, and the engagement between the engagement step 4a of the worm wheel 4 and the toggle lever 5 is performed. The toggle lever 5 is rotated clockwise by the engagement of the joint 5a.
トグルレバー 5の回転はリンク 6を介して中継レバー 7を反時計方向に 回転させ、 トグルばね 8を圧縮する （図 2 ( a ) 参照）。  Rotation of the toggle lever 5 rotates the relay lever 7 counterclockwise through the link 6 to compress the toggle spring 8 (see FIG. 2 (a)).
ウォームホイ一ル 4の回転によりトグルレバー 5の回転が進み、 トグル レバ一 5とリンク 6が直線上に位置すると、 トグルレバー 5にトルクが作 用しない死点の状態となる （図 2 ( b ) 参照）。  When the rotation of the worm wheel 4 causes the rotation of the toggle lever 5 to advance, and the toggle lever 5 and the link 6 are located on a straight line, a dead point occurs in which torque does not act on the toggle lever 5 (Fig. 2 (b)). reference).
この死点を超えてさらに回転すると、 中継レバー 7の回転方向が時計方 向に反転し、 トグルばね 8の圧縮状態が釈放され、 加速されてトグルレバ 一 5をさらに時計方向に回転させ、 連結レバ一 1 3を時計方向に回転させ、 これに連結した操作ロッド 1 5を介して断路器 1 4を入り状態にする。 （図 2 ( c ) 参照）。  When the relay further rotates beyond the dead center, the rotation direction of the relay lever 7 is reversed in the clockwise direction, the compression state of the toggle spring 8 is released, the acceleration is accelerated, and the toggle lever 15 is further rotated in the clockwise direction. One 13 is rotated clockwise, and the disconnector 14 is turned on via the operation rod 15 connected to the one. (See Figure 2 (c)).
本発明は、 図 3に示すように、 回転方向によって異なる出力軸トルク特 性を備え、 一方の回転方向では回転初期が回転終期より大きく、 他方の回 転方向では回転初期が回転終期より小さい出力軸トルク特性を得ることが できる。 As shown in FIG. 3, the present invention has different output shaft torque characteristics depending on the rotation direction. In one rotation direction, the initial rotation is larger than the end of rotation, and the other is different. In the turning direction, an output shaft torque characteristic in which the initial rotation is smaller than the final rotation can be obtained.
本発明は、 トグルレバーとトグルばねの間に中継軸とリンクを設け、 中 継軸のレバー角度の設定により出力トルク特性を任意に設定して、 負荷に 応じたトルク特性が実現できる。  According to the present invention, the relay shaft and the link are provided between the toggle lever and the toggle spring, and the output torque characteristics can be arbitrarily set by setting the lever angle of the relay shaft, so that the torque characteristics according to the load can be realized.
無駄なエネルギーの放出を押さえることができるので、 ばね操作器をコ ンパクトにすることができる。 行程終期での過大なトルクの発生を押さえ ることができるので、 緩衝装置を小さくすることができる。 産業上の利用可能性  Since the release of useless energy can be suppressed, the spring actuator can be made compact. Since the generation of excessive torque at the end of the stroke can be suppressed, the size of the shock absorber can be reduced. Industrial applicability
本発明は、 出力トルク特性を任意に設定可能とし、 負荷に応じたトルク 特性が実現できる開閉器のばね操作器に利用できる。  INDUSTRIAL APPLICABILITY The present invention can be used for a spring operating device of a switch which can set an output torque characteristic arbitrarily and can realize a torque characteristic according to a load.
