Description

ガス遮断器Gas circuit breaker
　本発明は電極を互いに反対方向に駆動する双方向駆動機構を適用したガス遮断器に関する。 The present invention relates to a gas circuit breaker to which a bidirectional driving mechanism for driving electrodes in opposite directions is applied.
　高電圧の電力系統に用いるガス遮断器は、遮断動作途中の消弧ガス圧力上昇を利用し、圧縮ガスを電極間に生じるアークに吹き付けることで電流を遮断するパッファ形と呼ばれるものが一般的に用いられている。電極は油圧やばねなどの操作器で駆動される駆動側電極と対向して配置される被駆動側電極から成り、それぞれの電極は、通常接続時に主な電流経路を形成する主接触子と、遮断時にアークが生成されるアーク接触子で構成される。 A gas circuit breaker used for a high-voltage power system is generally called a puffer type that cuts off the current by blowing the compressed gas against the arc generated between the electrodes by using the arc extinguishing gas pressure rise during the interruption operation. It is used. The electrode consists of a driven side electrode arranged opposite to a driving side electrode driven by an actuator such as a hydraulic pressure or a spring, and each electrode has a main contact that forms a main current path during normal connection, Consists of arc contacts that generate an arc when interrupted.
　パッファ形ガス遮断器の遮断性能を向上させるために、従来固定されていた被駆動側電極を駆動側電極の駆動方向と反対方向に駆動する双方向駆動方式が提案され、大きく分けて二つの方式がある。 In order to improve the shut-off performance of the puffer-type gas circuit breaker, a bidirectional driving method has been proposed in which the driven electrode, which has been fixed in the past, is driven in the direction opposite to the driving direction of the driving electrode. There is.
　一つは、被駆動側の主接触子とアーク接触子を同時に駆動するもので、例えば、特許文献１には、ラックアンドピニオン方式が提案されている。この発明では、被駆動側主接触子根元で被駆動側アーク接触子を固定し、駆動側の絶縁ノズル先端と被駆動側の主接触子根元にラックを取り付け、その間でピニオンが回転することで被駆動側主接触子及びアーク接触子を駆動側とは反対方向に駆動するものである。 One is to drive the driven main contact and arc contact at the same time. For example, Patent Document 1 proposes a rack and pinion system. In this invention, the driven-side arc contact is fixed at the driven-side main contact root, the rack is attached to the driving-side insulating nozzle tip and the driven-side main contact root, and the pinion rotates between them. The driven main contact and the arc contact are driven in the opposite direction to the drive side.
　もう一つは、被駆動側の主接触子を固定しアーク接触子を駆動するもので、例えば、特許文献２には、フォーク型レバーによる方式が提案されている。フォークの窪み部に駆動側の動きに連動したピンが接触することでフォーク型レバーが回動し、これを開閉軸方向の往復運動に変換することで、被駆動側アーク電極を駆動側電極の駆動方向と反対方向に駆動するものである。 The other is to fix the driven main contact and drive the arc contact. For example, Patent Document 2 proposes a method using a fork-type lever. The fork-type lever rotates when a pin linked to the movement on the driving side comes into contact with the depression of the fork, and this is converted into a reciprocating motion in the opening / closing axis direction, so that the driven-side arc electrode is connected to the driving-side electrode. It is driven in the direction opposite to the driving direction.

　遮断器の遮断状態での絶縁耐圧を満足させるためには、電圧階級に応じて定まる電極の絶縁距離を確保する必要があり、絶縁距離は駆動側・被駆動側の主接触子間距離及びアーク接触子間距離で概ね決まる。一方、通常接続状態から遮断状態に至るには、それぞれの接触子はある程度通電状態を保ったまま移動する必要があるが、アーク接触子は主接触子が開極した後しばらくは通電状態に保つ必要があるため、一般にアーク接触子間の移動距離は主接触子間の移動距離に比べ大きくなる。 In order to satisfy the withstand voltage of the circuit breaker in the interrupted state, it is necessary to secure an electrode insulation distance determined according to the voltage class. The insulation distance is the distance between the main contacts on the drive side and the driven side and the arc. Generally determined by the distance between contacts. On the other hand, in order to move from the normal connection state to the cutoff state, each contactor needs to move while maintaining a certain energization state, but the arc contactor is kept energized for a while after the main contactor is opened. Since it is necessary, the moving distance between the arc contacts is generally larger than the moving distance between the main contacts.
　特許文献1では、被駆動側主接触子を駆動させるため、相対的に駆動側の移動距離を小さくでき操作エネルギーを小さくできる。一方、主接触子とアーク接触子は締結されているため、アーク接触子間の移動距離を確保するためには、被駆動側主接触子の移動距離を必要以上に大きくする必要がある。 In Patent Document 1, since the driven main contactor is driven, the moving distance on the driving side can be relatively reduced, and the operation energy can be reduced. On the other hand, since the main contact and the arc contact are fastened, in order to secure the movement distance between the arc contacts, it is necessary to increase the movement distance of the driven side main contact more than necessary.
　特許文献２では、移動距離が大きい被駆動側アーク接触子のみを駆動させるため、被駆動側アーク接触子の移動距離を小さくでき、双方向駆動機構部がコンパクトになる。一方、被駆動側主接触子は駆動させないため、主接触子間の移動距離を確保するためには、特許文献１よりも駆動側の移動距離を大きくする必要があり操作エネルギーは大きくなる。 In Patent Document 2, since only the driven-side arc contact having a large moving distance is driven, the moving distance of the driven-side arc contact can be reduced, and the bidirectional drive mechanism is compact. On the other hand, since the driven main contact is not driven, it is necessary to make the drive-side moving distance larger than that of Patent Document 1 in order to secure the moving distance between the main contacts, and the operation energy becomes large.
　前記課題を解決するために、本発明に係るガス遮断器は、密封タンク内に駆動側電極と被駆動側電極を対向して設け、前記駆動側電極は駆動側主接触子と駆動側アーク主接触子を有し、前記被駆動側電極は被駆動側主接触子と被駆動側アーク接触子を有し、前記駆動側主接触子及び前記駆動側アーク接触子は操作器に接続され、前記被駆動側主接触子及び前記被駆動側アーク電極は双方向駆動機構部に連結され、双方向駆動機構部（１０）は、駆動側電極からの駆動力を受ける第一駆動側連結ロッド（１１）及び第二駆動側連結ロッド（２７）と、被駆動側アーク接触子（５）に接続した被駆動側アーク接触子連結部材（１４）と、被駆動側主接触子（３）に接続した被駆動側連結筒案内部材（１６）と、第一駆動側連結ロッド（１１）の動作に対して被駆動側アーク接触子連結部材（１４）及び被駆動側連結筒案内部材（１６）を同時に反対方向に動作させる第一レバー（１２）と、第二駆動側連結ロッド（２７）の動作に対して被駆動側アーク接触子連結部材（１４）のみを反対方向に動作させる第二レバー（２８）を備え、遮断動作前半に第一レバー（１２）を回動させることで被駆動側主接触子（３）と被駆動側アーク接触子（５）を同時に駆動し、遮断動作後半に第二レバー（２８）を回動させることで被駆動側アーク接触子（５）のみを駆動する双方向駆動機構を備えたことを特徴とする。 In order to solve the above problems, a gas circuit breaker according to the present invention is provided with a driving side electrode and a driven side electrode facing each other in a sealed tank, and the driving side electrode includes a driving side main contact and a driving side arc main. The driven side electrode has a driven side main contact and a driven side arc contact, the driving side main contact and the driving side arc contact are connected to an operating device, and The driven-side main contact and the driven-side arc electrode are connected to a bidirectional driving mechanism, and the bidirectional driving mechanism (10) receives a first driving-side connecting rod (11 that receives a driving force from the driving-side electrode. ) And the second driving side connecting rod (27), the driven side arc contact connecting member (14) connected to the driven side arc contact (5), and the driven side main contact (3). Of the driven side connecting cylinder guide member (16) and the first driving side connecting rod (11).

The side main contact (3) and the driven side arc contact (5) are driven simultaneously, and only the driven side arc contact (5) is driven by rotating the second lever (28) in the latter half of the shut-off operation. A bidirectional driving mechanism is provided.
　本発明によれば、駆動側の移動距離と被駆動側主接触子の移動距離を必要最小限に抑えられるため、操作エネルギーを小さくすることができる。また、駆動側の移動距離を必要最小限とすることで、駆動側・被駆動側の動作伝達をするレバーを小さくすることができ、双方向駆動機構部をコンパクトにすることができる。 According to the present invention, since the moving distance on the driving side and the moving distance of the driven main contactor can be minimized, the operation energy can be reduced. Further, by minimizing the moving distance on the driving side, the lever for transmitting the operation on the driving side and the driven side can be reduced, and the bidirectional driving mechanism can be made compact.

In addition, the following is an example of implementation to the last, and is not intended to limit the content of the invention to the following specific embodiment. The invention itself can be carried out in various modes according to the contents described in the claims. In the following embodiments, an example of a circuit breaker having a mechanical compression chamber and a thermal expansion chamber will be described. However, the present invention can be applied to, for example, a circuit breaker having only a mechanical compression chamber.

The driving side electrode has a driving side main contact 2 and a driving side arc contact 4, and the driven electrode has a driven side main contact 3 and a driven side arc contact 5.

The drive side arc contact 4 connected to the two drive side connection rods 27 and the drive side main contact 2 are driven to the opposite side.

The second drive side connecting rod 27 is limited in vertical displacement by a groove provided in the guide 19 and can move only in the horizontal direction with respect to the opening / closing operation axis of the blocking portion.
　第二レバー２８に切り込まれた第二レバー溝カムＡ３３と第二駆動側連結ロッド溝カム３１及び、ガイド１９に切り込まれたガイド溝カムＣ３２に第三可動ピン３０を連通する。 The third movable pin 30 communicates with the second lever groove cam A33 and the second drive side connecting rod groove cam 31 cut into the second lever 28 and the guide groove cam C32 cut into the guide 19.
　第二レバーの回転運動により第二レバー２８に切り込まれた第二レバー溝カムＢ３７が、溝内を通る第四可動ピン３４に力を伝達する。第四可動ピン３４は、被駆動側アーク接触子連結部材１４に切り込まれた被駆動側アーク接触子連結部材溝カムＢ３５の曲線部３５Ｂと、ガイド１９に切り込まれたガイド溝カムＤ３６それぞれに連通され、それぞれの溝カム内を移動することで、被駆動側アーク接触子連結部材１４を第一駆動側連結ロッド１１及び第二駆動側連結ロッド２７と反対方向に駆動する。これにより、被駆動側アーク接触子連結部材１４と連結する被駆動側アーク接触子５が、第一駆動側連結ロッド１１及び第二駆動側連結ロッド２７と連結される駆動側アーク接触子４と反対側に駆動される。 The second lever groove cam B37 cut into the second lever 28 by the rotational movement of the second lever transmits force to the fourth movable pin 34 passing through the groove. The fourth movable pin 34 includes a curved portion 35B of the driven-side arc contactor connecting member groove cam B35 cut into the driven-side arc contactor connecting member 14, and a guide groove cam D36 cut into the guide 19, respectively. The driven arc contact connecting member 14 is driven in the opposite direction to the first driving side connecting rod 11 and the second driving side connecting rod 27 by moving in the respective groove cams.

　第二駆動側連結ロッド溝カム３１の第一直線部３１Ａ、第二直線部３１Ｃに第三可動ピン３０が位置するとき、または、被駆動側アーク接触子連結部材溝カムＢ３５の直線部３５Ａに第四可動ピン３４が位置するときには第二レバー２８は位置保持され、第二駆動側連結ロッド溝カム３１の連結部３１Ｂに第三可動ピン３０が位置し、かつ、被駆動側アーク接触子連結部材溝カムＢ３５の曲線部３５Ｂに第四可動ピン３４が位置するときには第二レバー２８は回動可能となる。 When the third movable pin 30 is positioned on the first straight portion 31A and the second straight portion 31C of the second drive side connecting rod groove cam 31, or on the straight portion 35A of the driven side arc contactor connecting member groove cam B35. When the four movable pins 34 are positioned, the second lever 28 is held in position, the third movable pin 30 is positioned at the connecting portion 31B of the second drive side connecting rod groove cam 31, and the driven side arc contact connecting member. When the fourth movable pin 34 is positioned on the curved portion 35B of the groove cam B35, the second lever 28 can be rotated.
　被駆動側アーク接触子連結部材１４及び被駆動側連結筒案内部材１６はガイド１９に設けられた溝により上下方向の変位を制限され、遮断部の開閉動作軸と水平方向のみ移動可能となる。 The driven-side arc contact connecting member 14 and the driven-side connecting cylinder guide member 16 are limited in vertical displacement by grooves provided in the guide 19, and can move only in the horizontal direction with respect to the opening / closing operation axis of the blocking portion.
　双方向駆動機構１０と駆動側との連結は、例えば図２に示すように、ノズル８に締結リング３８を取り付け、締結リング３８に駆動側連結ロッド１１の先端部が貫通する穴及び駆動側連結ロッド２７の先端部が貫通する穴を設け、第一駆動側締結ねじ３９及び第二駆動側締結ねじ４０をナットで締め付ける構造とする。 For example, as shown in FIG. 2, the bidirectional driving mechanism 10 is connected to the driving side by attaching a fastening ring 38 to the nozzle 8, a hole through which the tip of the driving side connecting rod 11 passes and a driving side connection. A hole through which the tip of the rod 27 passes is provided, and the first drive side fastening screw 39 and the second drive side fastening screw 40 are tightened with nuts.
　第一レバー固定ピン１３は一本の部材によりガイド１９及び第一レバー１２を貫通する構成としてもよいが、図３及び図４に示すように、２本の部材としてそれぞれをガイド１９の両端に設け、第一レバー１２を両側から回動自在に保持する構成とするのが望ましい。 The first lever fixing pin 13 may be configured to penetrate the guide 19 and the first lever 12 by a single member. However, as shown in FIGS. 3 and 4, two members are provided at both ends of the guide 19. It is desirable that the first lever 12 be provided so as to be rotatable from both sides.
　第一レバー固定ピン１３がガイド１９から外れないようにするには、例えば、ピンの両端に溝を切り込みそれぞれに第一レバー固定ピン止め輪４１をはめ込むことで実現できる。 The first lever fixing pin 13 can be prevented from being detached from the guide 19 by, for example, cutting grooves at both ends of the pin and inserting the first lever fixing pin retaining ring 41 into each of the pins.
　このような構成とすることで、第一レバー固定ピン１３が第一駆動側連結ロッド１１に干渉するおそれなく設計することが可能となるので、設計自由度が向上する。 With such a configuration, the first lever fixing pin 13 can be designed without the possibility of interfering with the first drive side connecting rod 11, so that the degree of design freedom is improved.
　また、第二レバー固定ピン２９は図３及び図４に示すように一本の部材によりガイド１９を貫通する構成としてもよいが、２本の部材としてそれぞれをガイド１９の両端に設け、第二レバー２９を片側ずつ回動自在に保持する構成としてもよい。 Further, as shown in FIGS. 3 and 4, the second lever fixing pin 29 may be configured to penetrate the guide 19 by one member, but two members are provided at both ends of the guide 19, It is good also as a structure which hold | maintains the lever 29 rotatably one side at a time.
　第二レバー固定ピン２９がガイド１９から外れないようにするには、例えば、ピンの両端に溝を切り込み、それぞれに第二レバー固定ピン止め輪４４をはめ込むことで実現できる。 Securing the second lever fixing pin 29 from the guide 19 can be realized, for example, by cutting grooves at both ends of the pin and inserting the second lever fixing pin retaining ring 44 into each of the grooves.
　第一可動ピン１７、第二可動ピン２２、第三可動ピン３０、第四可動ピン３４は、動作伝達を滑らかにするため、一本の部材によりガイド１９を貫通する構成とするのが望ましい。 It is desirable that the first movable pin 17, the second movable pin 22, the third movable pin 30, and the fourth movable pin 34 have a configuration in which the guide 19 is penetrated by a single member in order to make motion transmission smooth.
　第一可動ピン１７、第二可動ピン２２、第三可動ピン３０がガイド１９から外れないようにするには、例えば、ピンの両端に溝を切り込み、それぞれに第一可動ピンピン止め輪４２、第二可動ピン止め輪４３、第三可動ピン止め輪４５をはめ込むことで実現できる。 In order to prevent the first movable pin 17, the second movable pin 22, and the third movable pin 30 from being removed from the guide 19, for example, grooves are cut at both ends of the pin, and the first movable pin pin retaining ring 42, This can be realized by fitting the second movable pin retaining ring 43 and the third movable pin retaining ring 45.
　第四可動ピン３４を同様の止め輪による締結にすると、ガイド１９を飛び出し、被駆動側連結筒案内部材１６と干渉する。そのため、第四可動ピン３４はガイド１９を飛び出さない長さとし、第四可動ピン３４の両端位置は被駆動側連結筒案内部材１６のガイド１９側端面で規定するようにする。 When the fourth movable pin 34 is fastened by a similar retaining ring, the guide 19 pops out and interferes with the driven side connecting cylinder guide member 16. Therefore, the fourth movable pin 34 has a length that does not protrude the guide 19, and both end positions of the fourth movable pin 34 are defined by the end surface of the driven side connecting cylinder guide member 16 on the guide 19 side.

When the movement distance of the driven-side arc contact 5 becomes longer, it is necessary to lengthen the lever. With this configuration, the lever can be suppressed to the minimum necessary length, and the bidirectional drive mechanism can be made compact. it can.
