Description
本発明はガス遮断器及びその投入動作用ばねの調整方法に係り、特に、ガス遮断器の投入動作を行うための駆動力源となる投入動作用ばねにおけるばね力を調整するものに好適なガス遮断器及びその投入動作用ばねの調整方法に関する。
The present invention relates to a gas circuit breaker and a method of adjusting a closing operation spring, and more particularly, a gas suitable for adjusting a spring force in a closing operation spring as a driving force source for performing a closing operation of the gas circuit breaker. The present invention relates to a circuit breaker and a method for adjusting a spring for closing the circuit breaker.
一般に、ガス遮断器においては、遮断部接点が高速度で開と閉の位置間を移動しなければならないため、３相それぞれに操作器を持つ各相操作形のガス遮断器では、各相間の閉極時間のばらつきが規格により規定されている。この各相間の閉極時間のばらつきを規定値内に揃える調整方法の一つとして、投入動作用ばねのばね力の初期設定値を調整する場合がある。この投入動作用ばねのばね力の初期設定値の調整には、投入動作用ばね部をガス遮断器から取り外して行うことが多い。
In general, in a gas circuit breaker, the circuit breaker contact must move between the open and closed positions at a high speed. Variations in the closing time are defined by the standard. One method of adjusting the variation in the closing time between the phases within a specified value is to adjust the initial setting value of the spring force of the closing operation spring. Adjustment of the initial setting value of the spring force of the closing operation spring is often performed by removing the closing operation spring portion from the gas circuit breaker.
このようなことから、特許文献１には、開閉装置用操作機構において、投入動作用ばねのばね力を、大がかりな専用治具を用いることなく、簡素な構成で投入動作用ばね部を取り外さないで調整することを可能とすることが開示されている。
For this reason, in Patent Document 1, in the operation mechanism for the switching device, the spring force of the closing operation spring is not removed with a simple configuration without using a large dedicated jig. It is disclosed that it is possible to make adjustments.
即ち、特許文献１には、投入動作用ばねの端面に配置したばね受けの背面にばね受け支持体を配置し、このばね受け支持体にジャッキボルト用ねじ孔を貫通して設け、このジャッキボルト用ねじ孔にジャッキ用ボルトをねじ込むことにより、ばね受け及び投入動作用ばねを押し下げてばね受け支持体とばね受けとの間に隙間を作り、その隙間にばね力調整用スぺーサを挿入し、投入動作用ばねの使用高さを変えることで、投入動作用ばねのばね力を調整することが開示されている。
That is, in Patent Document 1, a spring support is disposed on the back surface of a spring receiver disposed on the end face of the closing operation spring, and a screw hole for a jack bolt is provided through the spring support, and this jack bolt is provided. By screwing the jack bolt into the screw hole, the spring receiver and the spring for closing operation are pushed down to create a gap between the spring holder support and the spring holder, and a spring force adjusting spacer is inserted into the gap. Further, it is disclosed that the spring force of the closing operation spring is adjusted by changing the usage height of the closing operation spring.
一方、ガス絶縁開閉装置の輸送コスト低減が求められており、そのために、ガス絶縁開閉装置を一体でコンテナ輸送することが要求されている。ガス絶縁開閉装置を一体でコンテナ輸送するためには、機器全体の低層化が課題である。
On the other hand, it is required to reduce the transportation cost of the gas insulated switchgear, and for that purpose, it is required to transport the gas insulated switchgear in a container. In order to transport the gas insulated switchgear as a single container, it is a problem to reduce the overall height of the equipment.
この低層化の課題は、通常は、ガス遮断器の下部に投入動作用ばねが収納されている投入動作用ばね収納ケースと遮断動作用ばねが収納されている遮断動作用ばね収納ケースを備えているばね操作器を、ガス遮断器の前面に、該ガス遮断器と一直線上に配置することで解決できる。
The problem of lowering the layer is normally provided with a closing operation spring storage case in which a closing operation spring is stored in a lower part of the gas circuit breaker and a blocking operation spring storage case in which a blocking operation spring is stored. This can be solved by arranging the existing spring actuator on the front surface of the gas circuit breaker and in line with the gas circuit breaker.
しかしながら、上述の如く、遮断動作用ばねを投入動作用ばねの上部に配置すると、投入動作用ばねのばね力を調整しようとしても、遮断動作用ばねに遮られて投入動作用ばねにアクセスするのが難しいものとなる。このため、投入動作用ばねのばね力の調整作業を行うことが困難になってしまう。
However, as described above, when the shut-off operation spring is arranged on the upper part of the closing operation spring, even if an attempt is made to adjust the spring force of the closing operation spring, it is blocked by the shut-off operation spring and accesses the closing operation spring.

この投入動作用ばねのばね力の調整作業を行うためには、ばね操作器の本体を取り外すことが考えられるが、ばね操作器の本体を取り外すとなると、そのためにボルトの取外し、ばね操作器のジャッキアップ、ローラ取付け、移動、ばね力調整、移動、ローラ取外し、遮断器本体に取付け等の作業を行う必要があり、作業負担が増大する。

However, when the main body of the spring operating device is removed, the bolt is removed for this purpose. It is necessary to perform operations such as jack-up, roller attachment, movement, spring force adjustment, movement, roller removal, and attachment to the breaker body, which increases the work load.
また、特許文献１では、ばね受け、ばね力調整用スペーサ及びばね受け支持体を固定ボルトで一体に固定する必要があると共に、ばね力調整用スペーサを挿入するためにばね受け支持体とばね受けとの間に隙間を作る必要がある等、そのばね力調整のために作業負担が増大してしまう。

As a result, the blocking action spring 5 is compressed via the blocking action link 21 and the blocking action spring receiver 25.
遮断動作用ばね収納ケース７と、この遮断動作用ばね収納ケース７の下部に設置された投入動作用ばね収納ケース６は、図３に示すように、それぞれの中心軸が横方向（水平方向）にずらして配置されている。
As shown in FIG. 3, the closing operation spring storage case 7 and the closing operation spring storage case 6 installed at the lower part of the blocking operation spring storage case 7 have their central axes in the horizontal direction (horizontal direction). It is arranged to shift to.
また、投入動作用ばね収納ケース６側のリンク機構部３の側端部上方には、図２に示すように、作業用孔１１が形成されている。この作業用孔１１は、ばね操作器１の上方から見て遮断動作用ばね収納ケース７により隠れない位置に設けられるのが好ましく、しかも、図４に示すように、作業用孔１１の大きさ及びその上部は、投入動作用ばね４のばね力を調整するためのラチェットレンチ２４等の作業用工具を挿入し作業できるスペースが確保できるような大きさ及び位置になっていることが必要となる。なお、この作業用孔１１は、通常（投入動作用ばね４のばね力を調整する作業のとき以外或いはその他の作業以外）は、カバー等により塞がれて異物の侵入を防いでいる。
Further, as shown in FIG. 2, a work hole 11 is formed above the side end of the link mechanism 3 on the side of the loading operation spring storage case 6. The working hole 11 is preferably provided at a position that is not hidden by the shut-off operation spring storage case 7 when viewed from above the spring operating unit 1 and, as shown in FIG. And the upper part thereof needs to be sized and positioned so as to secure a space where a work tool such as a ratchet wrench 24 for adjusting the spring force of the closing operation spring 4 can be inserted. . Note that the work hole 11 is normally blocked by a cover or the like to prevent intrusion of foreign matter (other than when adjusting the spring force of the closing operation spring 4 or other work).
作業用孔１１を有する投入動作用ばね収納ケース６の内部においては、投入動作用ばね４が、その一端が背板１４に当接するように配置して固定され、投入動作用ばね４の他端が、ばね受け８に当接するように配置して固定されている。
In the inside of the closing operation spring housing case 6 having the working hole 11, the closing operation spring 4 is arranged and fixed so that one end thereof is in contact with the back plate 14, and the other end of the closing operation spring 4 is arranged. Are arranged and fixed so as to abut against the spring receiver 8.
図２に示す如く、投入カム１３とは反対側の端部外周部には、ばね受け８の中央を通してねじ部９ａが形成されたばね受け支持部９が配置されており、このばね受け支持部９は、投入カム１３に連結する投入動作用リンク２２の一端に接続されていると共に、ねじ部９ａには、ばね受け８の中央部を介して調整用ナット１０を螺合することにより、ばね受け８とばね受け支持部９が連結され、投入動作用ばね４のばね力が調整される。
As shown in FIG. 2, a spring receiving support 9 having a threaded portion 9 a formed through the center of the spring receiver 8 is disposed on the outer peripheral portion of the end opposite to the closing cam 13. Is connected to one end of a closing link 22 connected to the closing cam 13 and is screwed into the threaded portion 9a with the adjusting nut 10 through the center portion of the spring receiving 8 to thereby obtain a spring bearing. 8 and the spring support portion 9 are connected, and the spring force of the closing operation spring 4 is adjusted.
次に、遮断部接点の切（開）状態から遮断部接点の入（閉）状態に移行する動作を、以下に説明する。
Next, the operation of shifting from the cut (open) state of the breaker contact to the on (closed) state of the breaker contact will be described below.
通常、ガス遮断器１５に投入指令が入力されると、投入動作用ばね４の制御機構が作動して、圧縮状態にある投入動作用ばね４の規制を解き、投入動作用ばね４を放勢させる。
この際には、投入動作用ばねケース６の一端がリンク機構部３に剛に結合されているため、投入動作用ばね４及びばね受８が紙面上下方向に変位しても、投入動作用ばねケース６の振動は抑制されている。 Normally, when a closing command is input to thegas circuit breaker 15, the control mechanism of the closing operation spring 4 is actuated to release the restriction of the closing operation spring 4 in the compressed state and release the closing operation spring 4. Let
At this time, since one end of the closingoperation spring case 6 is rigidly coupled to the link mechanism portion 3, even if the closing operation spring 4 and the spring receiver 8 are displaced in the vertical direction on the paper surface, the closing operation spring is provided. The vibration of the case 6 is suppressed.
この際には、投入動作用ばねケース６の一端がリンク機構部３に剛に結合されているため、投入動作用ばね４及びばね受８が紙面上下方向に変位しても、投入動作用ばねケース６の振動は抑制されている。 Normally, when a closing command is input to the
At this time, since one end of the closing
投入動作用ばね４の放勢に伴い、投入動作用リンク２２を介して投入カム１３及び回転軸２３が反時計回りに回動する。投入カム１３の反時計回りの回動に伴い、投入カム１３の外周面がメインレバー１２の外周面を押圧してメインレバー１２を時計回りに回動させる。これにより、遮断動作用リンク２１及び遮断動作用ばね受２５を介して遮断動作用ばね５が圧縮される。これにより、遮断部接点が切（開）状態から入（閉）状態に移行する。
As the closing operation spring 4 is released, the closing cam 13 and the rotating shaft 23 rotate counterclockwise via the closing operation link 22. As the input cam 13 rotates counterclockwise, the outer peripheral surface of the input cam 13 presses the outer peripheral surface of the main lever 12 to rotate the main lever 12 clockwise. As a result, the blocking action spring 5 is compressed via the blocking action link 21 and the blocking action spring receiver 25. Thereby, the interruption | blocking part contact | movement transfers to an on (closed) state from an OFF (open) state.
また、図２に示す如く、ばね受け８にはばね受け支持部９が嵌る凹部８ａが形成されており、調整用ナット１０を締めたり緩めたりすることで、凹部８ａ内をばね受け支持部９が移動し、ばね受け８が変位（図２の左右方向に移動）することになる。
Further, as shown in FIG. 2, the spring receiver 8 is formed with a recess 8a into which the spring receiver support portion 9 is fitted. By tightening or loosening the adjustment nut 10, the spring receiver support portion 9 is formed inside the recess 8a. And the spring receiver 8 is displaced (moved in the left-right direction in FIG. 2).
これにより、３相の可動接触子１７と固定接触子１８の閉極時間を同一時間に（各相の閉極時間が一致）するのを目的とした投入動作用ばね４のばね力の調整が可能となる。
As a result, adjustment of the spring force of the closing operation spring 4 for the purpose of making the closing times of the three-phase movable contact 17 and the stationary contact 18 the same time (the closing times of the respective phases coincide) is achieved. It becomes possible.
以下、本実施例に係るガス遮断器１５の投入動作用ばね４のばね力の調整方法について、図４を用いて説明する。なお、この投入動作用ばね４のばね力の調整は、工場内における組立時或いは現地での据え付け時に行うものである。
Hereinafter, a method for adjusting the spring force of the closing spring 4 of the gas circuit breaker 15 according to this embodiment will be described with reference to FIG. The adjustment of the spring force of the closing operation spring 4 is performed at the time of assembly in the factory or installation at the site.
通常、相分離型の３相ガス遮断器を組込んだガス開閉装置は、複数器並べて配置されることが多くある。この場合、相分離型の３相ガス遮断器の全相が、両側を遮断器に挟まれているため、側面から機器の調整をすることが困難である。
Usually, a plurality of gas switchgears incorporating phase-separated three-phase gas circuit breakers are often arranged side by side. In this case, since all the phases of the phase separation type three-phase gas circuit breaker are sandwiched between the circuit breakers on both sides, it is difficult to adjust the device from the side.
全相のガス遮断器１５の調整をする際には、ガス遮断器１５を取外してして作業する必要があるが、投入動作用ばね４のばね力の調整のように、据付後１回行われる作業については、ガス遮断器１５を取外さずに行うことができれば作業性は向上する。
When adjusting the gas circuit breaker 15 for all phases, it is necessary to work with the gas circuit breaker 15 removed. However, the adjustment is performed once after installation as in the adjustment of the spring force of the closing operation spring 4. The workability is improved if it can be performed without removing the gas circuit breaker 15.
また、相分離型の３相ガス遮断器に限らず、遮断器の周囲に十分な作業場所を確保できない場合についても、ばね操作器１を取外すことなく投入動作用ばね４のばね力の調整ができれば作業性が向上する。
Further, not only in a phase separation type three-phase gas circuit breaker, but also in a case where a sufficient working place cannot be secured around the circuit breaker, the spring force of the closing operation spring 4 can be adjusted without removing the spring actuator 1. Workability will improve if possible.
上述の通り、本実施例におけるガス遮断器１５は、投入動作用ばね収納ケース６と遮断動作用ばね収納ケース７の中心軸を水平方向にずらして配置しているため、ばね操作器１の上方から投入動作用ばね収納ケース６にアクセスして、投入動作用ばね４のばね力調整作業を行うことが可能である。
As described above, the gas circuit breaker 15 in the present embodiment is arranged so that the center axes of the closing operation spring storage case 6 and the disconnection operation spring storage case 7 are shifted in the horizontal direction. It is possible to access the closing operation spring storage case 6 to adjust the spring force of the closing operation spring 4.
即ち、まず、投入動作用ばね収納ケース６に設けられた作業用孔１１のカバーを外し、作業用孔１１よりラチェットレンチ２４等の作業用工具を挿入し、このラチェットレンチ２４を調整用ナット１０に装着する（図４参照）。そして、ラチェットレンチ２４を回転させることで、ばね受け支持部９のねじ部に螺合された調整用ナット１０が増し締め又は緩められ、ばね受け８が図２の左右方向に移動されることで変位させる。つまり、調整用ナット１０を締めることで、投入動作用ばね４が蓄勢されて反力を大きくし、調整用ナット１０を緩めることで、投入動作用ばね４が放勢されて反力を小さくすることができる。
That is, first, the cover of the work hole 11 provided in the loading operation spring storage case 6 is removed, a work tool such as a ratchet wrench 24 is inserted from the work hole 11, and the ratchet wrench 24 is connected to the adjusting nut 10. (See FIG. 4). Then, by rotating the ratchet wrench 24, the adjustment nut 10 screwed into the threaded portion of the spring support portion 9 is tightened or loosened, and the spring support 8 is moved in the left-right direction in FIG. Displace. That is, by tightening the adjustment nut 10, the closing operation spring 4 is stored to increase the reaction force, and by loosening the adjustment nut 10, the closing operation spring 4 is released to reduce the reaction force. can do.
以上説明した本実施例とすることにより、密封タンク２とリンク機構部３及びばね操作器１が一直線上に配置されていることで、機器全体の低層化が可能なことは勿論、ばね操作器１の本体を取り外すことなく、作業負担が増大しない簡単な作業で投入動作用ばね４のばね力の調整を行うことができる。
By adopting the present embodiment as described above, the sealing tank 2, the link mechanism section 3 and the spring operating device 1 are arranged in a straight line, so that the entire device can be lowered, and of course the spring operating device. The spring force of the closing operation spring 4 can be adjusted by a simple operation that does not increase the work load without removing the main body 1.
なお、上述した実施例では、作業用孔１１を、投入動作用ばね収納ケース６側のリンク機構部３の側端部上方に形成した例について説明したが、作業環境が揃えば、投入動作用ばね収納ケース６のリンク機構部３の側端部下方に、作業用孔１１を形成してもよい。
