Description

本発明は、真空バルブを用いた真空遮断器に係り、特に、開閉操作を容易に行える操作機構を備えた真空遮断器に関する。   The present invention relates to a vacuum circuit breaker using a vacuum valve, and more particularly to a vacuum circuit breaker provided with an operation mechanism that can be easily opened and closed.

従来、この種の真空遮断器の操作機構には、操作方向を、例えば左右方向から上下方向に変換するスコットラッセル機構が用いられ、真空遮断器の外形形状を小型にできることが知られている（例えば、特許文献１参照）。   Conventionally, the operation mechanism of this type of vacuum circuit breaker has been known to use a Scott Russell mechanism that changes the operation direction, for example, from the left-right direction to the up-down direction, and can reduce the external shape of the vacuum circuit breaker ( For example, see Patent Document 1).

しかしながら、スコットラッセル機構は、複数枚の板状のリンクがピンで連結され、操作方向を変換しているので、リンクやピンの摩擦抵抗が大きくなる問題があった。また、リンクやピンを含めた操作機構に過大の荷重が掛かる問題があった。
特開２０００−２９４０９３号公報 （第３ページ、図１） However, the Scott Russell mechanism has a problem that the frictional resistance of the link and the pin increases because a plurality of plate-like links are connected by pins and the operation direction is changed. In addition, there is a problem that an excessive load is applied to the operation mechanism including the link and the pin.
JP 2000-294093 A (3rd page, FIG. 1)

上記の従来の真空遮断器においては、次のような問題がある。
操作方向を変換するスコットラッセル機構では、リンクやピンの摩擦抵抗が大きく、過大の荷重が各部に掛かることがあった。このため、摩擦抵抗を抑制し、操作機構からの操作力を容易に伝達することのできる機構が望まれていた。また、操作方向を変換しないものであっても、操作力が容易に伝達されるものが望まれていた。 The above-described conventional vacuum circuit breaker has the following problems.
In the Scott Russell mechanism that changes the operation direction, the frictional resistance of the link and the pin is large, and an excessive load may be applied to each part. For this reason, a mechanism capable of suppressing frictional resistance and easily transmitting the operation force from the operation mechanism has been desired. Moreover, even if the operation direction is not changed, it is desired that the operation force can be easily transmitted.

本発明は上記問題を解決するためになされたもので、操作力を容易に伝達する機構を備えた真空遮断器を提供することを目的とする。   The present invention has been made to solve the above problems, and an object thereof is to provide a vacuum circuit breaker having a mechanism for easily transmitting an operating force.

上記目的を達成するために、本発明の真空遮断器は、接離自在の一対の接点を有する真空バルブと、前記真空バルブに連結された第１の可動軸と第２の可動軸との軸方向の芯ずれを吸収する自動調芯機構と、前記第２の可動軸に連結された前記接点の開閉操作を行う操作機構とを備えたことを特徴とする。   In order to achieve the above object, a vacuum circuit breaker according to the present invention comprises a vacuum valve having a pair of contactable and separable contacts, and a shaft of a first movable shaft and a second movable shaft connected to the vacuum valve. An automatic alignment mechanism that absorbs misalignment in the direction and an operation mechanism that opens and closes the contact connected to the second movable shaft are provided.

本発明によれば、回転自在の球体を有する自動調芯機構を連結して操作機構からの操作力を伝達しているので、軸方向の芯ずれによる伝達ロスが抑えられ、真空バルブの開閉操作を容易にすることができる。   According to the present invention, the automatic alignment mechanism having a rotatable sphere is connected to transmit the operation force from the operation mechanism, so that transmission loss due to axial misalignment is suppressed, and the vacuum valve opening / closing operation is performed. Can be made easier.

以下、図面を参照して本発明の実施例を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing a configuration of a vacuum circuit breaker according to an embodiment of the present invention, FIG. 2 is a top view showing a configuration of a vacuum circuit breaker according to an embodiment of the present invention, and FIG. FIG. 4 is an enlarged top view showing the operation mechanism of the vacuum circuit breaker according to the embodiment of the present invention, and FIG. 5 is a vacuum according to the embodiment of the present invention. It is an enlarged front view explaining operation | movement of the operation mechanism of a circuit breaker. In each figure, the fixed pin is hatched and the movable pin is outlined.

図１に示すように、真空遮断器は、取り付け板１を境として、遮断部２ａと操作機構部２ｂとに分かれて構成されている。   As shown in FIG. 1, the vacuum circuit breaker is configured to be divided into a blocking part 2 a and an operation mechanism part 2 b with a mounting plate 1 as a boundary.

遮断部２ａには、接離自在の一対の接点３を有する真空バルブ４がエポキシ樹脂でモールドされ、三相分が取り付け板１に固定されている。真空バルブ４の可動側には、軸方向に移動自在の可動電極５が連結され、接続導体６に摺動接触している。可動電極５の軸方向には、絶縁操作ロッド７が連結され、絶縁操作ロッド７に固定された第１の可動軸８が取り付け板１の開口孔を移動自在に貫通している。また、図２に示すように、真空バルブ４は、例えば図示上方が遮断用であり、図示下方が断路用となっている。遮断用と断路用の真空バルブ４の主回路部には、他の電気機器が接続される。   A vacuum valve 4 having a pair of contact points 3 that can be separated from each other is molded with epoxy resin in the blocking portion 2 a, and the three-phase portion is fixed to the mounting plate 1. A movable electrode 5 movable in the axial direction is connected to the movable side of the vacuum valve 4, and is in sliding contact with the connection conductor 6. An insulating operation rod 7 is connected in the axial direction of the movable electrode 5, and a first movable shaft 8 fixed to the insulating operation rod 7 penetrates the opening hole of the mounting plate 1 movably. Moreover, as shown in FIG. 2, the vacuum valve 4 is for interruption | blocking, for example in the upper part of the figure, and for the disconnection in the lower part of the figure. Other electric devices are connected to the main circuit portion of the vacuum valve 4 for blocking and disconnecting.

操作機構部２ｂには、三相分の第１の可動軸８に連結されたシャフト９が設けられている。第１の可動軸８の外周には、接点３が閉路したときに、接触荷重を加えるワイプバネ１０が設けられている。そして、中相の第１の可動軸８には、操作方向のずれを吸収する自動調芯機構１１が連結され、更に操作方向を図示上下方向から図示左右方向に変換する方向変換機構１２に連結されている。方向変換機構１２には、例えば永久磁石を有する電磁アクチュエータのような操作機構１３が連結されている。また、上相と中相間と、中相と下相間とのシャフト９には、接点３を開路方向に移動させる開路バネ１４が設けられている。   The operating mechanism 2b is provided with a shaft 9 connected to the first movable shaft 8 for three phases. A wipe spring 10 that applies a contact load when the contact 3 is closed is provided on the outer periphery of the first movable shaft 8. The first movable shaft 8 in the middle phase is connected to an automatic alignment mechanism 11 that absorbs a deviation in the operation direction, and further connected to a direction changing mechanism 12 that converts the operation direction from the vertical direction in the drawing to the horizontal direction in the drawing. Has been. An operation mechanism 13 such as an electromagnetic actuator having a permanent magnet is connected to the direction changing mechanism 12. Further, the shaft 9 between the upper phase and the middle phase and between the middle phase and the lower phase is provided with an open spring 14 for moving the contact 3 in the open direction.

次に、自動調芯機構１１と方向変換機構１２を図３乃至図５を参照して説明する。図３、図４に示すように、シャフト９は、三角形状の二枚の第１のリンク１５の一方の頂点部を貫通固定している。第１のリンク１５の他方の頂点部には、第１の可動軸８端に当接する可動ピン１６が挟持されている。また、第１のリンク１５の異なる他方の頂点部には、第１のリンク１５間に設けられた球体１７を回転自在に固定する可動ピン１８が挟持されている。球体１７は、内面球状で球体１７を回転自在に支える球面滑り軸受け１９に収納されている。球面滑り軸受け１９には、第１の可動軸８の軸方向に配置された第２の可動軸２０が固定されている。   Next, the automatic alignment mechanism 11 and the direction changing mechanism 12 will be described with reference to FIGS. As shown in FIGS. 3 and 4, the shaft 9 penetrates and fixes one apex of the two triangular first links 15. A movable pin 16 that is in contact with the end of the first movable shaft 8 is sandwiched at the other vertex of the first link 15. In addition, a movable pin 18 that rotatably fixes the sphere 17 provided between the first links 15 is sandwiched between the different apexes of the first link 15. The spherical body 17 is housed in a spherical sliding bearing 19 which is spherical on the inner surface and supports the spherical body 17 in a rotatable manner. A second movable shaft 20 disposed in the axial direction of the first movable shaft 8 is fixed to the spherical sliding bearing 19.

ここで、第１のリンク１５、可動ピン１６、１８、球体１７、球面滑り軸受け１９が自動調芯機構１１の構成部品となる。そして、自動調芯機構１１は、第１の可動軸８に連結された回転自在の球体１７と、第２の可動軸２０に連結された球体１７を回転自在に支える球面滑り軸受け１９とで構成されると言える。   Here, the first link 15, the movable pins 16 and 18, the sphere 17, and the spherical sliding bearing 19 are components of the automatic alignment mechanism 11. The automatic alignment mechanism 11 includes a rotatable sphere 17 connected to the first movable shaft 8 and a spherical sliding bearing 19 that rotatably supports the sphere 17 connected to the second movable shaft 20. It can be said that.

第２の可動軸２０は、三角形状の第２のリンク２１の一方の頂点部に、可動ピン２２で連結されている。第２のリンク２１の他方の頂点部には、操作機構１３に連結された第３の可動軸２３が設けられ、可動ピン２４で連結されている。第２のリンク２１の異なる他方の頂点部には、第２のリンク２１を回動自在に固定する固定ピン２５が設けられている。   The second movable shaft 20 is connected to one apex portion of the triangular second link 21 by a movable pin 22. A third movable shaft 23 connected to the operation mechanism 13 is provided at the other vertex of the second link 21, and is connected by a movable pin 24. A fixing pin 25 that rotatably fixes the second link 21 is provided at the other apex of the second link 21.

ここで、第２のリンク２１、可動ピン２２、２４、固定ピン２５が方向変換機構１２の構成部品となり、第２の可動軸２０と第３の可動軸２３との移動方向を変換するものとなる。   Here, the second link 21, the movable pins 22 and 24, and the fixed pin 25 become components of the direction changing mechanism 12, and changes the moving direction of the second movable shaft 20 and the third movable shaft 23. Become.

移動方向は、第３の可動軸２３の軸方向に対して、これと直交する方向に第２の可動軸２０を移動させるものである。なお、第３の可動軸２３と第２の可動軸２０との移動方向が必ずしも直交せず、組立て調整などによって角度がばらついていても、方向変換機構１２の許容する数度程度の動作範囲内であれば、それを直交する方向という。   The moving direction is to move the second movable shaft 20 in a direction perpendicular to the axial direction of the third movable shaft 23. In addition, even if the moving directions of the third movable shaft 23 and the second movable shaft 20 are not necessarily orthogonal and the angles vary due to assembly adjustment or the like, they are within an operating range of several degrees allowed by the direction changing mechanism 12. If so, it is called a perpendicular direction.

次に、自動調芯機構１１と方向変換機構１２の動作を図５を参照して説明する。   Next, operations of the automatic alignment mechanism 11 and the direction changing mechanism 12 will be described with reference to FIG.

操作機構１３の動作により、第３の可動軸２３が図示上下方向に移動すると、第２のリンク２１が固定ピン２５を支点として回動する。すると、第２の可動軸２０が図示左右方向に移動し、移動方向が変換される。第２の可動軸２０が図示左右方向に移動すると、第１のリンク１５がシャフト９を支点として回動する。この回動により、可動ピン１６に当接している第１の可動軸８が図示左右方向に移動し、接点３を開閉することができる。   When the third movable shaft 23 moves in the illustrated vertical direction by the operation of the operation mechanism 13, the second link 21 rotates about the fixed pin 25 as a fulcrum. Then, the second movable shaft 20 moves in the horizontal direction in the figure, and the movement direction is converted. When the second movable shaft 20 moves in the horizontal direction in the figure, the first link 15 rotates about the shaft 9 as a fulcrum. By this rotation, the first movable shaft 8 in contact with the movable pin 16 moves in the left-right direction in the figure, and the contact 3 can be opened and closed.

ここで、第２の可動軸２０と第１の可動軸８は、互いに図示左右方向に移動するものの、必ずしも同一の軸線上を移動せず、所謂軸方向の芯ずれを起こすことがある。この芯ずれによる摩擦力などの応力は、球体１７が可動ピン１８を軸として図示左右方向に回転するとともに、図示上下方向にも回動して吸収される。このため、第２の可動軸２０と第１の可動軸８間には、無理な応力が加わらず、操作機構１３からの操作力の伝達ロスを抑えることができる。   Here, although the second movable shaft 20 and the first movable shaft 8 move in the left-right direction in the drawing, they do not necessarily move on the same axis, and so-called axial misalignment may occur. Stress such as a frictional force caused by the misalignment is absorbed by rotating the sphere 17 in the horizontal direction in the figure with the movable pin 18 as an axis and also rotating in the vertical direction in the figure. For this reason, an unreasonable stress is not applied between the second movable shaft 20 and the first movable shaft 8, and the transmission loss of the operation force from the operation mechanism 13 can be suppressed.

また、真空バルブ４は、絶縁材料でモールドされているので、外形形状を小型化することができ、更に、方向変換機構１２により操作機構１３の操作方向を変換しているので、真空遮断器の全体形状を小型化することができる。   Further, since the vacuum valve 4 is molded with an insulating material, the outer shape can be reduced in size, and the operation direction of the operation mechanism 13 is changed by the direction changing mechanism 12, so that the vacuum circuit breaker The overall shape can be reduced in size.

上記実施例の真空遮断器によれば、操作機構１３の操作力を方向変換機構１２を介して回転自在の球体１７を有する自動調芯機構１１で伝達しているので、互いに同一方向に移動する第２の可動軸２０と第１の可動軸８とに軸方向の芯ずれなどが起きても、球体１７と球面滑り軸受け１９とで芯ずれによる応力を吸収し、操作力のロスを抑え、真空バルブ４の開閉をスムースに行うことができる。   According to the vacuum circuit breaker of the above embodiment, the operation force of the operation mechanism 13 is transmitted via the direction changing mechanism 12 by the automatic alignment mechanism 11 having the rotatable sphere 17 so that they move in the same direction. Even if axial misalignment or the like occurs between the second movable shaft 20 and the first movable shaft 8, the spherical body 17 and the spherical sliding bearing 19 absorb the stress due to misalignment and suppress the loss of operating force. The vacuum valve 4 can be opened and closed smoothly.

なお、上記実施例では、操作機構１３に方向変換機構１２と自動調芯機構１１とを連結して説明したが、方向変換機構１２を取り外し、自動調芯機構１１のみを用いた場合にも、球体１７と球面滑り軸受け１９とで軸方向の芯ずれによる応力を吸収し、操作力のロスを抑えることができる。しかしながら、方向変換機構１２を用いたものにおいて、軸方向の芯ずれが起き易いので、自動調芯機構１１で応力を吸収する効果を大きく出せることができる。   In the above embodiment, the direction changing mechanism 12 and the automatic alignment mechanism 11 are connected to the operation mechanism 13. However, even when the direction changing mechanism 12 is removed and only the automatic alignment mechanism 11 is used, The spherical body 17 and the spherical sliding bearing 19 can absorb stress due to axial misalignment and suppress loss of operating force. However, in the case where the direction changing mechanism 12 is used, axial misalignment is likely to occur, so that the effect of absorbing stress by the automatic aligning mechanism 11 can be greatly increased.
