Description

【0001】
【発明の属する技術分野】
この発明は例えば電動操作方式の断路器などに好ましく用いることができる開閉器の操作機構切り離し装置に関するものである。
【0002】
【従来の技術】
従来の電動操作式断路器においては、断路器とこの断路器の駆動源である電動操作機構とがリンク機構によって機械的に連結され、電動操作機構の駆動力がリンク機構を介して断路器の操作部材に伝達される方式が用いられる。そして、上記リンク機構を構成するレバー類の連結部や枢支部などに用いられる固定ピンは、ピン穴からはみ出した部分のピン体外周面にリング状の溝を形成し、その溝にスナップリングなどのC型固定金具を装着することにより脱落防止が図られている。
【0003】
一方、例えば断路器の試験を行う際などに、電動操作機構の駆動力を断路器に伝達させないように切り離しが容易にできる装置の要請があるが、従来装置では切り離すときに、連結ピンを外すために先ず脱落防止用のC型固定金具を専用の工具を用いて取り外し、その次に、ピンを引き抜く作業が行われていた。一方、例えば縫製分野においては、リンク機構が多用されるミシンで、軸部材と連結ピン部材との間のレバー長の調節作業を容易に行うことができるようにしたリンク機構が提案されている(例えば、特許文献1参照。)。

【発明が解決しようとする課題】
従来の断路器は以上のような構造であったため、電動操作機構の駆動力を切り離す際には、レバー類を連結している固定ピンを引き抜くために、C型固定金具を取り外した後に固定ピンを引き抜く作業が必要であり、作業性が悪く切り離し操作に時間がかかるという問題点があった。また、C型固定金具を取り外す際には工具が必要であり、さらには取り外しの際にC型固定金具の変形、損傷、紛失などが発生し易いという問題点があった。さらに、設備を復旧するための接続操作を実施する際にも時間がかかるという問題点があった。また、特許文献1の発明では構造が複雑で適用が困難であるなどの問題があった。
【0006】
この発明は上記のような従来技術の課題を解決するためになされたもので、断路器などの開閉器とそれを駆動する駆動源との間の操作機構の切り離し及び接続が容易で、作業時間の短縮ができる開閉器の操作機構切り離し装置を提供することを目的としている。
【0007】
【課題を解決するための手段】
この発明による開閉器の操作機構切り離し装置は、回動可能に枢支され開閉器及び駆動源の何れか一方に連結されたピン穴及び連結部を有する伝達レバーと、この伝達レバーの連結部に回動可能に枢着され、かつ上記開閉器及び駆動源の何れか他方に連結され、上記伝達レバーのピン穴に対向する所定位置に固定用の連通穴を有する駆動レバーと、ピン体の一端部に回動自在に設けられ該ピン体の軸方向に向きを揃えることによりピン穴に挿脱し得、ピン体の軸方向に略直交する方向に向きを変えることによりピン穴に係止し得る係止片を有する挿脱ピンとを備え、上記開閉器と駆動源を連結するときは上記挿脱ピンを上記ピン穴及び連通穴を貫通して装着し、開閉器と駆動源を切り離すときは上記挿脱ピンを引き抜くようにしたものである。
【0008】
【発明の実施の形態】
実施の形態1.
図1ないし図6はこの発明の実施の形態1になる断路器の操作機構切り離し装置の要部を説明する図であり、図1は断路器(図示省略)が開成状態でリンク確立時の状態を示す正面図、図2は図1の側面図、図3は用いる伝達レバー(a)及び駆動レバー(b)の形状を示す平面図、図4はこの発明に用いる挿脱ピンを示す正面図(図4(a))、及び側面図(図4(b))、図5は断路器が閉成状態でリンク接続時の状態を示す正面図、図6は断路器が開成状態でリンク切り離し時の状態を示す側面図である。なお、各図を通じて同一符合は同一もしくは相当部分を示している。
【0009】
図に示すように、フレームなどの固定部1に設けられた一対の軸受部2には中間軸3が回動可能に支承されている。この中間軸3には、溝形の伝達レバー4と、図示を省略している断路器の操作部材に連結される断路器駆動レバー5と、所定時に中間軸3の回動を阻止するためのストッパーレバー6が固着されて取り付けられている。上記伝達レバー4の所定位置には、図3(a)に示すように貫通孔からなる連結部4aとピン穴4bが設けられており、該連結部4aには駆動レバー7が固定ピン8によって回動可能に枢着されている。なお、Cは固定ピンの脱落を防止するためのC型固定金具(スナップリング)である。
【0010】
上記駆動レバー7の所定位置には、図3(b)に示すように上記伝達レバー4の連結部4aに連結するための連結穴7aと、伝達レバー4のピン穴4bに対向する位置に貫通された連通穴7bと、ロッドレバー9と連結するための駆動源連結穴7cがそれぞれ設けられている。ロッドレバー9の図の上端部は固定ピン13によって駆動レバー7に連結され、図の下端部は駆動源である電動操作機構10の出力軸10aに固定された出力レバー11に固定ピン14によって連結されている。
【0011】
そして、上記断路器と駆動源のリンクを確立するときには、固定ピン8を支点に駆動レバー7を回動して上記伝達レバー4のピン穴4bと駆動レバー7の連通穴7bを合致させて同軸とし、図4に示す挿脱ピン12を挿通することによって伝達レバー4と駆動レバー7とを一体化し、駆動レバー7が中間軸3を支点として伝達レバー4と一体的に回動するようになされている。
【0012】
上記挿脱ピン12は、図4に示すようにピン体12aの一端部に設けられた溝状の切り欠き12bに、ピン12cによって矢印A方向に回動自在に支承された係止片12dと、頭部12eを備えたものであり、係止片12dをピン体12aの軸方向に揃えたときに、伝達レバー4のピン穴4bと駆動レバー7の連通穴7bに挿通可能であり、ピン体12aの軸方向に略直交する向きに偏向したとき(図4(b)の状態)には、頭部12eと係止片12dによってピン穴4bに係止される。
【0013】
なお、溝形の伝達レバー4と中間軸3の個々の形状と取り付け方式、駆動レバー7とロッドレバー9との固定ピン13、ロッドレバー9と電動操作機構10の出力レバー11との固定ピン14は、従来装置と同様にC型固定金具Cによって固定されている。また、固定部1の図の上方部には、所定時にストッパーレバー6を固定するための固定穴15aを有するストッパーレバー固定部材15が取り付けられているが、その動作については下記実施の形態2で説明する。
【0014】
次に、上記のように構成された実施の形態1の動作を説明する。図1及び図2の断路器開成状態から閉成状態にするには、駆動源である電動操作機構10の出力レバー11を図2の時計方向に回動させると、これに従来と同様の固定ピン14で連結されたロッドレバー9が図2の上方向に駆動され、ロッドレバー9の上端部で固定ピン13と連結された駆動レバー7、及びこれと一体の伝達レバー4を中間軸3のまわりに反時計方向に回動することにより、断路器駆動レバー5が反時計方向に回動し、図示を省略している断路器の操作部材を駆動して断路器を閉成し、図5の状態となる。なお、断路器を開成状態にするには出力レバー11を逆の方向に動作させればよい。
【0015】
一方、断路器の試験やメンテナンス等のため、断路器と駆動源とのリンク機構を切り離す必要が生じたときは、伝達レバー4と駆動レバー7を連結している挿脱ピン12の係止片12dをピン体12aの軸方向に揃えることにより該挿脱ピン12をピン穴4b及び連通穴7bから引き抜くことで、電動操作機構10の伝達力を中間軸3に伝達しないように切り離し操作が容易にできる。図6は該挿脱ピン12を引き抜いた状態で出力レバー11が断路器閉成方向(時計方向)に回動されても、駆動レバー7が伝達レバー4との連結部に設けられた固定ピン8のまわりに回動するのみで、中間軸3が回動しない状態を示している。
【0016】
上記のように、この実施の形態1によれば、駆動源の駆動力を断路器に伝達するときには挿脱ピン12を伝達レバー4のピン穴4b及び駆動レバー7の連通穴7bに挿通することにより伝達レバー4と駆動レバー7とを一体化し、駆動源の駆動力を断路器から切り離すときには、上記挿脱ピン12を引き抜くことにより断路器と切り離すようにしたので、構造が簡単で、切り離し及び接続の切り替えが容易にできる。またC型固定金具(スナップリング)が不要であるので、専用の工具も不要となり、切り離し及び接続操作を短時間に行うことができる。また取り外したC型固定金具の変形、損傷、紛失などの問題も解消できる。従って、安全性、信頼性の高い断路器の切り離し装置を得ることができる。
【0017】
実施の形態2.
図7は、この発明の実施の形態2による断路器の操作機構切り離し装置の要部を模式的に示す図であり、図7(a)はストッパーレバーを挿脱ピンで固定した状態を示す側面図、図7(b)は図7(a)のストッパーレバーの一部を破断して示す一部断面正面図である。ストッパーレバー固定部材15は、ストッパーレバー6の先端部を受け入れる溝部15bを有し、この溝部15bの両壁部に挿脱ピン12を挿入するための固定穴15aが中間軸3と平行に設けられている。
【0018】
また、中間軸3に固着されたストッパーレバー6の先端部には、上記ストッパーレバー固定部材15の固定穴15aに対応する位置に固定用の貫通孔6aが設けられている。また、挿脱ピン12の係止片12dを回動操作を行うために、図7(b)に示すストッパーレバー固定部材15の前面部はアクセス可能に開放されている。その他の構成は上記実施の形態1と同様であるので説明を省略する。
【0019】
次に、上記のように構成された実施の形態2の動作を説明する。断路器の点検や試験時には、上記実施の形態1における断路器開成状態(図2の状態)で、挿脱ピン12を引き抜き、駆動源と断路器が切り離されるが、引き抜いた挿脱ピン12をストッパーレバー固定部材15の固定穴15aからストッパーレバー6の貫通穴6aに挿通することにより、ストッパーレバー6をストッパーレバー固定部材15に固定する。その他の動作は上記実施の形態1と全く同様である。
【0020】
上記のように、実施の形態2によれば、上記実施の形態1と同様の効果に加えて、断路器と断路器を駆動する電動操作機構を切り離した状態において中間軸3の回転を規制することができ、これにより断路器の不要動作を防止することができる付随効果が得られる。また、引き抜いた挿脱ピン12をそのままストッパーレバー6の係止に使うので、紛失防止にもなる。
【0021】
ところで、上記実施の形態の説明では、伝達レバー4を被駆動側の断路器側に設け、駆動レバー7を駆動源の側に配設したが、必ずしもこれに限定されるものではなく、駆動側と被駆動側を逆にしても同様の効果が得られる。また、挿脱ピンは、一端部に係止片、他端部に頭部を設けた例について説明したが、両端部に係止片を設けても差し支えない。また、係止片12dが動作中に振動等で回動するのを防止する手段を設けることは信頼性向上の上で望ましい。
【0022】
さらに、伝達レバー4は溝形に形成したが、これに限定されないことは勿論であり、例えば、板状でもよいし、駆動レバー7を溝形にしても良い。要するに開閉器と駆動源とのリンク機構に上記伝達レバー4と駆動レバー7を介在させれば同様の効果が期待できる。さらに、断路器駆動レバー5と伝達レバー4を中間軸3の異なる位置に設けた場合について説明したが必ずしもこれに限定されない。また、開閉器が断路器である場合について説明したが、例えば真空遮断器、ガス絶縁遮断器などの遮断器などであっても同様の効果が期待できる。その他、この発明の精神を逸脱しない範囲で種々の変形や変更が可能であることは言うまでもない。
【0023】
【発明の効果】
以上説明したように、この発明によれば開閉器と駆動源との操作機構の切り離し及びリンクの確立が容易で、作業時間の短縮ができる開閉器の操作機構切り離し装置を提供することができる。

[Prior art]
In a conventional electrically operated disconnector, the disconnector and an electrically operated mechanism that is a drive source of the disconnector are mechanically connected by a link mechanism, and the driving force of the electrically operated mechanism is connected to the disconnector via the link mechanism. A method of transmitting to the operation member is used. And the fixing pin used for the connecting part or the pivoting part of the levers constituting the link mechanism forms a ring-shaped groove on the outer peripheral surface of the pin body protruding from the pin hole, and a snap ring or the like is formed in the groove. The C-type fixing bracket is attached to prevent falling off.
[0003]
On the other hand, there is a demand for a device that can be easily disconnected so that the driving force of the electric operation mechanism is not transmitted to the disconnector, for example, when performing a test of the disconnector. For this purpose, first, the C-type fixing bracket for preventing the drop-off is removed by using a dedicated tool, and then the operation of pulling out the pin has been performed. On the other hand, for example, in the sewing field, a link mechanism has been proposed in which a lever length adjustment operation between a shaft member and a connecting pin member can be easily performed with a sewing machine that frequently uses a link mechanism ( For example, see Patent Document 1.)

In addition, a stopper lever fixing member 15 having a fixing hole 15a for fixing the stopper lever 6 at a predetermined time is attached to the upper portion of the fixing portion 1 in the figure. explain.
[0014]
Next, the operation of the first embodiment configured as described above will be described. To switch from the disconnector open state of FIGS. 1 and 2 to the closed state, the output lever 11 of the electric operation mechanism 10 as a driving source is rotated in the clockwise direction of FIG. The rod lever 9 connected by the pin 14 is driven upward in FIG. 2, and the drive lever 7 connected to the fixed pin 13 at the upper end of the rod lever 9 and the transmission lever 4 integrated therewith are connected to the intermediate shaft 3. By rotating counterclockwise around, the disconnector drive lever 5 rotates counterclockwise, and the disconnecting device operating member (not shown) is driven to close the disconnector. It becomes the state of. In addition, what is necessary is just to operate the output lever 11 to a reverse direction in order to open a disconnector.
[0015]
On the other hand, when it becomes necessary to disconnect the link mechanism between the disconnecting device and the driving source for testing or maintenance of the disconnecting device, the locking piece of the insertion / removal pin 12 connecting the transmission lever 4 and the driving lever 7 By pulling out the insertion / removal pin 12 from the pin hole 4b and the communication hole 7b by aligning 12d in the axial direction of the pin body 12a, the separation operation is easy so as not to transmit the transmission force of the electric operation mechanism 10 to the intermediate shaft 3.

In addition, problems such as deformation, damage and loss of the removed C-shaped fixing bracket can be solved. Therefore, it is possible to obtain a disconnector disconnecting device with high safety and reliability.
[0017]
Embodiment 2. FIG.
FIG. 7 is a diagram schematically showing the main part of the operating mechanism disconnecting device for disconnector according to Embodiment 2 of the present invention, and FIG. 7 (a) is a side view showing a state in which the stopper lever is fixed with an insertion / removal pin. FIG. 7 and FIG. 7B are partial cross-sectional front views showing a part of the stopper lever of FIG. The stopper lever fixing member 15 has a groove portion 15b for receiving the tip end portion of the stopper lever 6, and a fixing hole 15a for inserting the insertion / removal pin 12 is provided in parallel to the intermediate shaft 3 on both wall portions of the groove portion 15b. ing.
[0018]
Further, a fixing through-hole 6 a is provided at a position corresponding to the fixing hole 15 a of the stopper lever fixing member 15 at the tip of the stopper lever 6 fixed to the intermediate shaft 3. Further, in order to rotate the locking piece 12d of the insertion / removal pin 12, the front surface portion of the stopper lever fixing member 15 shown in FIG. 7B is opened to be accessible. Since other configurations are the same as those of the first embodiment, description thereof is omitted.
[0019]
Next, the operation of the second embodiment configured as described above will be described. When the disconnector is inspected or tested, the insertion / removal pin 12 is pulled out in the opened state of the disconnector in the first embodiment (the state shown in FIG. 2), and the drive source and the disconnector are disconnected. The stopper lever 6 is fixed to the stopper lever fixing member 15 by being inserted into the through hole 6 a of the stopper lever 6 from the fixing hole 15 a of the stopper lever fixing member 15. Other operations are the same as those in the first embodiment.
[0020]
As described above, according to the second embodiment, in addition to the same effects as those of the first embodiment, the rotation of the intermediate shaft 3 is restricted in a state where the disconnecting device and the electric operation mechanism that drives the disconnecting device are disconnected. As a result, an accompanying effect can be obtained in which unnecessary operation of the disconnector can be prevented. Further, since the extracted insertion / removal pin 12 is used as it is for locking the stopper lever 6, it can be prevented from being lost.
[0021]
By the way, in the description of the above embodiment, the transmission lever 4 is provided on the driven disconnector side and the drive lever 7 is provided on the drive source side. However, the present invention is not necessarily limited to this. The same effect can be obtained even if the driven side is reversed. Moreover, although the insertion / removal pin demonstrated the example which provided the locking piece in the one end part, and provided the head in the other end part, it does not interfere even if a locking piece is provided in both ends. It is desirable to improve the reliability by providing a means for preventing the locking piece 12d from rotating due to vibration during operation.

Furthermore, although the transmission lever 4 is formed in a groove shape, the transmission lever 4 is of course not limited to this, and may be, for example, a plate shape or the drive lever 7 in a groove shape. In short, the same effect can be expected if the transmission lever 4 and the drive lever 7 are interposed in the link mechanism between the switch and the drive source. Furthermore, although the case where the disconnector drive lever 5 and the transmission lever 4 are provided at different positions on the intermediate shaft 3 has been described, the present invention is not necessarily limited thereto. Moreover, although the case where the switch is a disconnector has been described, the same effect can be expected even with a circuit breaker such as a vacuum circuit breaker or a gas insulated circuit breaker. In addition, it goes without saying that various modifications and changes can be made without departing from the spirit of the present invention.
