従来より、高圧受配電設備においては、主回路を構成する遮断器，断路器等の 主回路機器を絶縁性ガスが封入された密閉容器内に収納していわゆるガス絶縁ス イッチギヤを構成し、相間絶縁寸法の縮小化や全体の小形化を図ると同時に、各 主回路機器の操作器や監視制御機器等を容器の前面に集約して操作，点検の作業 性を向上するようにしている。 Conventionally, in high-voltage power distribution equipment, circuit breakers, disconnectors, etc. that make up the main circuit have been The main circuit equipment is housed in an airtight container filled with insulating gas. The switch gear is configured to reduce the interphase insulation dimension and the overall size. Operation and inspection work is done by concentrating main circuit equipment controllers, monitoring and control equipment, etc. on the front of the container. I'm trying to improve my sexuality.
【０００３】 図４は、このようなガス絶縁スイッチギヤを示したものであり、縦長の密閉容 器１の上壁に計器用変流器及び零相変流器を内蔵したケーブルブッシング２を気 密に貫設すると共に、容器１の前壁に上から順に遮断器３，断路器４及び母線ブ ッシング５をそれぞれ気密に貫設し、容器１内において、ケーブルブッシング２ ，遮断器３，断路器４及び母線ブッシング５のそれぞれの端子間を導体により接 続して主回路を構成し、この容器１内にＳＦ6 ガス等の絶縁性ガスを大気圧より 高い圧力で封入している。FIG. 4 shows such a gas-insulated switchgear, in which a cable bushing 2 containing an instrument current transformer and a zero-phase current transformer is hermetically installed on the upper wall of a vertically long sealed container 1. At the same time, a circuit breaker 3, a disconnector 4, and a busbar bushing 5 are installed airtightly through the front wall of the container 1 in order from above. Each terminal of the bus bushing 5 is connected by a conductor to form a main circuit, and an insulating gas such as SF 6 gas is sealed in the container 1 at a pressure higher than atmospheric pressure.
【０００４】 さらに、容器１の前面に遮断器３及び断路器４のそれぞれの操作器６，７を配 設して前面操作を可能にすると共に、隣接盤間を連結するモールド母線８を母線 ブッシング５に前面より着脱自在に接続するようにしている。なお、９は天井よ り引き込まれたケーブルのケーブルコネクタである。0004 Furthermore, operating devices 6 and 7 for the circuit breaker 3 and the disconnector 4 are arranged on the front surface of the container 1. The molded busbar 8 that connects adjacent panels is installed as a busbar to enable front operation. It is connected to the bushing 5 in a detachable manner from the front side. Furthermore, 9 is the ceiling. This is the cable connector for the cable pulled in.
【０００５】 ところで、前述したようなガス絶縁スイッチギヤにあっては、容器１内に収納 された断路器４と容器１の前面に配置された操作器７とを容器１を気密に貫通し て連結する必要があるため、従来では、断路器４と操作器７とを容器１の一部を 構成する板材の両面にそれぞれ一体に取り付け、この組立体を容器１に組み込む ようにしており、例えば図５〜図７に示すような構成になっている。[0005] By the way, in the case of the gas-insulated switchgear as mentioned above, it is necessary to store it in the container 1. The disconnect switch 4 and the operating device 7 arranged on the front side of the container 1 are passed through the container 1 in an airtight manner. Conventionally, the disconnector 4 and the operating device 7 are connected by connecting a part of the container 1. Attach them integrally to both sides of the constituent plates, and incorporate this assembly into container 1. For example, the configuration is as shown in FIGS. 5 to 7.
【０００６】 これらの図面において、１０はベースであり、後面に断路器４，前面に操作器 ７がそれぞれ一体に取り付けられ、容器１の前壁に透設された角孔１１から断路 器４を容器１内に収納してベース１０により角孔１１を気密に閉塞するようにな っている。[0006] In these drawings, 10 is a base, with a disconnector 4 on the rear and an operating device on the front. 7 are integrally attached to each other, and a disconnection is established from a square hole 11 transparently provided in the front wall of the container 1. The container 4 is housed in the container 1, and the square hole 11 is airtightly closed by the base 10. ing.
【０００７】 ベース１０の後面に取り付けられた断路器４は、支持板１２の後面上部及び下 部にそれぞれ碍子１３，１４を介して３相の上部端子１５及び下部端子１６を左 右方向に相配列して支持し、各上部端子１５にそれぞれ固定接触子１７を固定す ると共に、各下部端子１６にそれぞれ可動ブレード１８を回動自在に支持し、支 持板１２に回転支持された左右方向の主軸１９を各相毎のレバー２０及びリンク ２１を介して各可動ブレード１８に連結する構成になっており、主軸１９の回動 により各可動ブレード１８が回動し、それぞれ固定接触子１７に接離する。[0007] The disconnect switch 4 attached to the rear surface of the base 10 is connected to the upper and lower rear surfaces of the support plate 12. A three-phase upper terminal 15 and a lower terminal 16 are connected to the left side through insulators 13 and 14, respectively. The fixed contacts 17 are fixed to each upper terminal 15 by supporting them in a phased manner in the right direction. At the same time, a movable blade 18 is rotatably supported on each lower terminal 16. A horizontal main shaft 19 rotatably supported by a holding plate 12 is connected to levers 20 and links for each phase. 21 to each movable blade 18, and the rotation of the main shaft 19 As a result, each movable blade 18 rotates and approaches and separates from the fixed contact 17, respectively.
【０００８】 また、ベース１０の前面に取り付けられた操作器７には前後方向の出力軸２２ が設けられ、これがベース１０に回転気密シール２３を介して貫通しており、容 器１内において出力軸２２の端部に操作器レバー２４を軸着すると共に、上下方 向に配設された丸棒状ロッド２５の上部にスリットを形成してこれにレバー２４ を連結し、かつ、ロッド２５の下部を半月状に切削してこれを前記主軸１９に固 定された断路器レバー２６に連結している。[0008] In addition, the operating device 7 attached to the front surface of the base 10 has an output shaft 22 in the front and rear direction. is provided, which penetrates the base 10 via a rotary airtight seal 23, and has a capacity. The operating lever 24 is attached to the end of the output shaft 22 in the device 1, and A slit is formed in the upper part of the round rod 25 arranged in the direction, and the lever 24 is inserted into the slit. The lower part of the rod 25 is cut into a half-moon shape and fixed to the main shaft 19. It is connected to a fixed disconnector lever 26.
【０００９】 したがって、操作器７の出力軸２２が反時計方向及び時計方向にそれぞれ回動 すると、レバー２４を介してロッド２５が上下動し、このロッド２５の動きによ りレバー２６を介して主軸１９に正逆方向の回転力が伝えられ、各相のブレード １８が固定接触子１７に接離することになる。[0009] Therefore, the output shaft 22 of the operating device 7 rotates counterclockwise and clockwise, respectively. Then, the rod 25 moves up and down via the lever 24, and this movement of the rod 25 causes Rotational force in the forward and reverse directions is transmitted to the main shaft 19 via the lever 26, and the blades of each phase are 18 comes into contact with and separates from the fixed contact 17.
【００１０】0010
前述した従来構成にあっては、容器１の内外に位置する断路器４，操作器７を 共通のベース１０に組み込むため、両者の連結部の寸法精度を上げることができ 、組立性も良好になるが、このようなガス密封式の場合、連結部が容器１を気密 に貫通するため、かなり高い寸法精度が必要となり、ベース１０を貫通した出力 軸２２に対する主軸１９の位置精度や両軸１９，２２間を連結する部品の加工精 度等が要求され、その管理が煩雑となり、かつ、高価なものになるといった問題 がある。 In the conventional configuration described above, the disconnector 4 and the operating device 7 located inside and outside the container 1 are connected to each other. Since it is assembled into a common base 10, it is possible to improve the dimensional accuracy of the connecting part between the two. However, in the case of such a gas-tight type, the connection part does not make the container 1 airtight. Since the output penetrates through the base 10, fairly high dimensional accuracy is required. The positional accuracy of the main shaft 19 with respect to the shaft 22 and the machining precision of the parts connecting the two shafts 19 and 22 The problem is that the management is complicated and expensive. There is.
【００１１】 本考案は、従来の技術の有するこのような問題点に留意してなされたものであ り、その目的とするところは、密閉容器の内外に位置する開閉器とその操作器と の連結部に高い寸法精度，位置精度を必要とすることなく、容器を気密に貫通し て両者間を連結することが可能なガス密封形開閉装置を提供することにある。[0011] The present invention has been made in consideration of these problems of the conventional technology. The purpose of this is to control the switches and their operating devices located inside and outside the sealed container. It can penetrate the container airtight without requiring high dimensional accuracy or positional accuracy for the connecting part. An object of the present invention is to provide a gas-sealed switchgear that can connect the two.
【００１２】0012
前記目的を達成するために、本考案のガス密封形開閉装置においては、絶縁性 ガスが封入された密閉容器に透設された開口部と、この開口部に遊挿されフラン ジ部が開口部の周縁に外部から気密に当接した軸受けと、フランジ部に透設され た複数の遊挿孔と、この各遊挿孔にそれぞれ遊挿して軸受けを容器に固定した複 数のボルトと、軸受けに気密かつ回転自在に支持され容器外において操作器に連 結された連結軸と、容器内における連結軸の端部に軸方向に形成され開閉器側の 軸の角軸部が嵌合した角穴とを備えてなるものである。 In order to achieve the above object, the gas-sealed switchgear of the present invention has an insulating property. An opening is made through the airtight container filled with gas, and a flan is loosely inserted into this opening. The flange part has a bearing that is in airtight contact with the periphery of the opening from the outside, and the flange part is transparent. multiple loose insertion holes, and a bearing fixed to the container by being loosely inserted into each of the loose insertion holes. It is airtightly and rotatably supported by several bolts and bearings and connected to the operating device outside the container. The connected connecting shaft and the connecting shaft formed in the axial direction at the end of the connecting shaft inside the container and located on the switch side. It is provided with a square hole into which a square shaft portion of the shaft is fitted.
【００１３】[0013]
前述の構成においては、操作器に連結された連結軸が軸受けに気密に支持され 、この軸受けがそのフランジ部を容器の開口部周縁に気密に当接してボルト止め されるため、容器内外の開閉器，操作器間を連結した連結軸が容器を気密に貫通 することになる。 In the above configuration, the connecting shaft connected to the operating device is airtightly supported by the bearing. , this bearing airtightly contacts the flange of the container with the periphery of the opening of the container and bolts it. Therefore, the connecting shaft that connects the switch and operating device inside and outside the container must pass through the container airtight. I will do it.
【００１４】 この場合、容器の開口部に遊挿された軸受けは、そのフランジ部の遊挿孔がボ ルトに対しいわゆるバカ孔となるため、連結軸に直交する平面において遊挿孔と ボルトとの間の隙間分の移動が可能となり、連結軸の開閉器側の軸に対する前記 平面における位置ずれを吸収でき、また、連結軸に軸方向に形成した角穴に開閉 器側の軸の角軸部を嵌合して両者間を連結するため、開閉器側の軸と連結軸との 軸方向のずれをこの嵌合深さを変えることにより吸収できる。[0014] In this case, when the bearing is loosely inserted into the opening of the container, the loose insertion hole in the flange part of the bearing is inserted into the opening of the container. Because it is a so-called blank hole for the bolt, it is not a loose insertion hole in the plane perpendicular to the connection axis. It is possible to move the connection shaft by the gap between the bolt and the shaft on the switch side. It can absorb positional deviation in the plane, and can be opened and closed in the square hole formed in the axial direction on the connecting shaft. In order to connect the two by fitting the square shaft part of the shaft on the switch side, the shaft on the switch side and the connecting shaft are connected. Displacement in the axial direction can be absorbed by changing the fitting depth.

実施例につき、図１〜図３を用いて説明する。なお、前記と同一符号は同一も しくは相当するものを示すものとする。 図２に示すように、絶縁性ガスが封入された密閉容器１の前面板における角孔 １１の左右側縁にそれぞれ支持金具１ａを溶接等により固着し、相配列が左右方 向の断路器４を角孔１１より容器１内に収納すると共に、断路器４の支持板１２ の両側をそれぞれ支持金具１ａに固定して断路器４を支持し、左右方向に設けら れた断路器４の主軸１９を容器１の右側壁近傍まで延設し、その軸端に図１に示 すように断面正方形の角軸部２７を形成する。 Examples will be described using FIGS. 1 to 3. Note that the same symbols as above also refer to the same numbers. or the equivalent shall be indicated. As shown in FIG. 2, a square hole in the front plate of the airtight container 1 filled with insulating gas The supporting metal fittings 1a are fixed to the left and right side edges of 11 by welding, etc., so that the phase arrangement is The disconnect switch 4 facing the opposite direction is housed in the container 1 through the square hole 11, and the support plate 12 of the disconnect switch 4 is Both sides of the disconnector 4 are fixed to the support fittings 1a to support the disconnector 4, and the The main shaft 19 of the disconnector 4 is extended to the vicinity of the right side wall of the container 1, and the shaft end is provided with a A corner shaft portion 27 having a square cross section is formed so as to have a square cross section.
【００１６】 図１に示すように、容器１の右側壁における主軸１９の延長線上の位置に円形 の開口部２８を透設し、これに容器１外から軸受け２９を取り付ける。[0016] As shown in FIG. 1, a circular An opening 28 is provided through the container 1, and a bearing 29 is attached to the opening 28 from outside the container 1.
【００１７】 この軸受け２９は、開口部２８に遊挿した筒部３０と開口部２８より十分大径 のフランジ部３１とからなり、フランジ部３１がこれに装着した環状のシール部 ３２を介して開口部２８の周縁に容器１外から気密に当接するようになっている 。[0017] This bearing 29 has a diameter sufficiently larger than that of the cylindrical portion 30 loosely inserted into the opening 28 and the opening 28. The flange part 31 is an annular seal part attached to the flange part 31. 32 to airtightly contact the periphery of the opening 28 from outside the container 1. .
【００１８】 開口部２８の周縁には、等間隔に配置された複数個，例えば４個のタップ穴３ ３が容器１外に開口して形成され、これにそれぞれ対応してフランジ部３１にタ ップ穴３３より大径の遊挿孔３４が透設されており、容器１外からボルト３５を 各遊挿孔３４に遊挿してタップ穴３３に螺合することにより軸受け２９が容器１ に取り付けられる。[0018] On the periphery of the opening 28, a plurality of, for example four, tapped holes 3 are arranged at equal intervals. 3 are formed with openings to the outside of the container 1, and correspondingly there are tabs on the flange portions 31. A loose insertion hole 34 with a larger diameter than the top hole 33 is provided through the hole, and a bolt 35 can be inserted from outside the container 1. By loosely inserting into each loose insertion hole 34 and screwing into the tapped hole 33, the bearing 29 is inserted into the container 1. can be attached to.
【００１９】 軸受け２９の筒部３０には、連結軸３６がその外周のシール部３７，３８を介 して気密かつ回転自在に支持され、抜け止め輪３９，４０により抜け止めされて おり、連結軸３６の右端部に断路器レバー４１が溶接等により一体に固着される と共に、連結軸３６の左端部に主軸１９の角軸部２７が嵌合する角穴４２が軸方 向に形成されている。[0019] A connecting shaft 36 is connected to the cylindrical portion 30 of the bearing 29 via seal portions 37 and 38 on its outer periphery. It is airtightly and rotatably supported, and is prevented from coming off by retaining rings 39 and 40. A disconnector lever 41 is integrally fixed to the right end of the connecting shaft 36 by welding or the like. At the same time, the square hole 42 into which the square shaft portion 27 of the main shaft 19 fits into the left end of the connecting shaft 36 is axially It is formed in the direction.
【００２０】 一方、ベース１０の前面に左右方向の出力軸２２を有する操作器７を設け、こ の出力軸２２を操作器７より右方へ導出すると共に、この軸端に操作器レバー２ ４を軸着し、両レバー２４，４１間をリンク４３で連結するようにしている。[0020] On the other hand, an operating device 7 having an output shaft 22 in the left and right direction is provided on the front surface of the base 10. The output shaft 22 of the controller 7 is led out to the right, and the controller lever 2 is connected to the end of this shaft. 4 is pivotally mounted, and both levers 24 and 41 are connected by a link 43.
【００２１】 このような構成にあっては、断路器４，操作器７間の連結機構の一部を構成す る連結軸３６が開口部２８に気密に取り付けられた軸受け２９を介して容器１を 気密に貫通することになり、操作器７の出力軸２２の回転が両レバー２４，４１ 及びリンク４３を介して連結軸３６に伝達され、さらに容器１内の主軸１９に伝 達されて断路器４の開閉動作が行われることになる。[0021] In such a configuration, a part of the connection mechanism between the disconnector 4 and the operating device 7 is A connecting shaft 36 connects the container 1 via a bearing 29 airtightly attached to the opening 28. The rotation of the output shaft 22 of the operating device 7 is caused by passing through the levers 24, 41 in an airtight manner. and is transmitted to the connecting shaft 36 via the link 43, and further transmitted to the main shaft 19 in the container 1. When the distance is reached, the disconnector 4 is opened and closed.
【００２２】 この場合、連結軸３６を支持した軸受け２９は、各ボルト３５と遊挿孔３４と の隙間を利用して上下，前後に移動することが可能であるため、主軸１９と連結 軸３６とに軸心ずれが生じてもこれを吸収することが可能であり、さらに、主軸 １９と連結軸３６との連結を角軸部２７と角穴４２との嵌合により行うため、両 者間に軸方向（左右方向）の寸法ずれが生じてもこの嵌合部で吸収でき、したが って、従来のように連結部の寸法精度を上げる必要がなくなる。 なお、本考案は、前述した断路器４だけでなく、遮断器，接地開閉器等の他の 開閉器の連結部にも適用できることは明らかである。[0022] In this case, the bearing 29 that supported the connecting shaft 36 is connected to each bolt 35 and the loose insertion hole 34. Since it is possible to move up and down and back and forth using the gap between the Even if misalignment occurs between the main shaft 36 and the main shaft, it is possible to absorb this. 19 and the connecting shaft 36 are connected by fitting the square shaft portion 27 and the square hole 42. Even if there is a dimensional deviation in the axial direction (left and right direction) between the two, it can be absorbed by this fitting part. Therefore, there is no need to increase the dimensional accuracy of the connecting portion as in the past. The present invention is applicable not only to the above-mentioned disconnector 4, but also to other circuit breakers, earthing switches, etc. It is clear that it can also be applied to the connection part of a switch.
