Description
【０００１】[0001]
本考案は複合一体型のキュービクル形ガス絶縁開閉装置に配設される避雷器に 関する。 The present invention relates to a lightning arrester installed in a cubicle type gas-insulated switchgear of a composite integrated type.
【０００２】[0002]
キュービクル形ガス絶縁開閉装置（以下Ｃ−ＧＩＳという）は用地難等の理由 による装置の縮小化に対応して実用化されたもので、各電気機器を複合一体化し てキュービクル内に収納している。このようなＣ−ＧＩＳでは電気設備技術基準 に基いて現地耐電圧試験を行わなくてはならないが、Ｃ−ＧＩＳに組込まれた避 雷器が耐電圧試験に耐えられない場合がある。このため耐電圧試験前に避雷器を 回路から切り離しておく必要があり、このような断路機能を備えた避雷器として は図３に示す構造のものが知られている（特公昭58−11726 ）。 The cubicle type gas-insulated switchgear (hereinafter referred to as C-GIS) was put into practical use in response to the downsizing of the device due to site difficulties, etc., and each electric device is combined and stored in the cubicle. .. In such C-GIS, on-site withstand voltage test must be conducted based on the electrical equipment technical standard, but the arrester incorporated in C-GIS may not be able to withstand the withstand voltage test. For this reason, it is necessary to disconnect the lightning arrestor from the circuit before the withstand voltage test, and a lightning arrester having such a disconnecting function is shown in Fig. 3 (Japanese Patent Publication No. 58-11726).
【０００３】 絶縁筒１の両端にフタ２を配設し、この絶縁筒１内に避雷器エレメント（以下 素子という）を３柱に分割して積層し収納する。この夫々の素子柱３の下側に線 路側電極４を配設し、素子柱３と線路側電極４を絶縁ロッド５で絶縁筒１内に吊 り下げ状態にて支持する。この３柱の素子柱３の中央の間隙に可動電極６を貫通 させ、この可動電極６と対向する下側のフタ２に固定電極７を配設する。固定電 極７には他の機器と避雷器を電気的に接続する接続導体が接続されている。この ように構成された避雷器の上側のフタ２にフランジ８を配設し、絶縁筒１をキュ ービクル９内に挿入して前記フランジ８をキュービクル９に固定する。Lids 2 are provided at both ends of the insulating cylinder 1, and a lightning arrester element (hereinafter referred to as an element) is divided into three pillars and stacked and housed in the insulating cylinder 1. A wire side electrode 4 is arranged below each of the element columns 3 and the element column 3 and the line side electrode 4 are supported by an insulating rod 5 in a suspended state in the insulating cylinder 1. The movable electrode 6 is penetrated through the gap in the center of the three element columns 3, and the fixed electrode 7 is disposed on the lower lid 2 facing the movable electrode 6. The fixed electrode 7 is connected to a connecting conductor that electrically connects the lightning arrester to another device. The flange 8 is arranged on the lid 2 on the upper side of the lightning arrester thus configured, and the insulating cylinder 1 is inserted into the cubicle 9 to fix the flange 8 to the cubicle 9.
【０００４】 このような従来の避雷器では可動電極６を上下動させることによって電路の形 成及び断路を行うことができる。即ち、Ｃ−ＧＩＳの耐電圧試験時には可動電極 ６を上方へ移動させて、固定電極７から可動電極６をひき出しておけばよい。In such a conventional lightning arrester, it is possible to form and disconnect the electric path by moving the movable electrode 6 up and down. That is, in the withstand voltage test of C-GIS, the movable electrode 6 may be moved upward so that the movable electrode 6 is pulled out from the fixed electrode 7.
【０００５】 しかしながら、このような従来の避雷器は線路側電極４と固定電極７の間に一 定の距離をあける必要があり、避雷器の縦方向の長さをおさえるために素子を２ 柱あるいは３柱に分割して積層する必要があった。このため避雷器の径が大きく なるうえ部品点数が増えるので避雷器の小型軽量化が難しく、断路操作時や避雷 器組立時の作業性が悪いという問題があった。However, in such a conventional lightning arrester, it is necessary to provide a fixed distance between the line-side electrode 4 and the fixed electrode 7, and in order to suppress the length of the lightning arrester in the vertical direction, two elements or three elements are used. It was necessary to divide it into pillars and stack them. For this reason, the diameter of the arrester becomes large and the number of parts increases, making it difficult to reduce the size and weight of the arrester, resulting in poor workability when disconnecting or assembling the arrester.
【０００６】[0006]
上述したように従来の避雷器は小型軽量化が困難なため断路操作等の際に作業 性が悪いという問題があった。そこで本考案の目的は単純構成で小型なうえ断路 操作も簡便な避雷器を提供することにある。 As described above, the conventional lightning arrester has a problem that workability is poor at the time of disconnection operation, etc., because it is difficult to reduce the size and weight. Therefore, an object of the present invention is to provide a lightning arrester which is simple in configuration, small in size, and easy to disconnect.
【０００７】[0007]
上記目的を達成するために本考案においては、断路器、しゃ断器等の開閉装置 をＳＦ6 ガスを充填したキュービクル内に配設したキュービクル形ガス絶縁開閉 装置に、断路可能に配設された避雷器において、前記避雷器の容器を前記キュー ビクル内に挿入された円筒部と前記キュービクルとの接合部であるフランジ部と を備えた絶縁性の密閉容器で構成し、前記円筒部の先端に前記開閉装置と着脱可 能な線路側端子を配設し、この線路側端子と電気的に接続された避雷器エレメン トを前記円筒部内に収納し、この円筒部と前記キュービクルの接触面に軸シール 材を配設し、前記フランジ部と前記キュービクルの接触面に面シール材を配設し たことを特徴とする避雷器を提供する。In order to achieve the above object, in the present invention, a lightning arrester is provided in a cubicle type gas-insulated switchgear in which a switchgear, a circuit breaker and other switchgear are arranged in a cubicle filled with SF 6 gas so as to be disconnectable. In the above, the container of the lightning arrester is composed of an insulating hermetic container having a cylindrical portion inserted into the cubicle and a flange portion which is a joint portion of the cubicle, and the opening / closing device is provided at a tip of the cylindrical portion. And a removable line-side terminal, the surge arrester element electrically connected to the line-side terminal is housed in the cylindrical part, and a shaft sealing material is placed on the contact surface between the cylindrical part and the cubicle. A lightning arrester is provided in which a face seal material is provided on a contact surface between the flange portion and the cubicle.
【０００８】[0008]
避雷器の密閉容器は円筒部とフランジ部を備え、円筒部とキュービクルとの接 触面には軸シール材が配設され、フランジ部とキュービクルとの接触面には面シ ールが配設されている。このため密閉容器とキュービクルはガス区分を異にし、 夫々のガス気密を保ったまま耐電圧試験前に断路することができる。 The lightning arrester closed container has a cylindrical part and a flange part.A shaft sealant is provided on the contact surface between the cylindrical part and the cubicle, and a face seal is provided on the contact surface between the flange part and the cubicle. ing. For this reason, the closed container and the cubicle have different gas divisions and can be disconnected before the withstand voltage test while maintaining the gas tightness of each gas.
【０００９】 即ち、避雷器をキュービクル内の開閉装置から断路するときは、密閉容器のフ ランジ部とキュービクルの接合をはずし、密閉容器をジャッキ等に固定して密閉 容器ごとキュービクル外へ摺動させる。この際密閉容器の円筒部先端に配設され た線路側端子とキュービクル内の開閉装置とが離れ、避雷器を回路から切り離す ことができる。That is, when disconnecting the lightning arrester from the opening / closing device in the cubicle, the flange portion of the closed container and the cubicle are disconnected, the closed container is fixed to a jack or the like, and the whole closed container is slid out of the cubicle. At this time, the line-side terminal arranged at the tip of the cylindrical portion of the closed container and the switchgear in the cubicle separate, and the lightning arrester can be separated from the circuit.
【００１０】 断路状態から通常の通電状態にするためには密閉容器をキュービクル内へ摺動 させ、開閉装置と避雷器の線路側端子を接触させ、キュービクルと避雷器のフラ ンジ部を接合する。従って開閉装置、線路側端子、避雷器エレメントという電路 が形成される。この状態では円筒部に配設された軸シール材及びフランジ部に配 設された面シール材によって二重シール構造が形成され、キュービクル内のＳＦ6 ガスの気密が確実に保たれる。In order to change from the disconnected state to the normal energized state, the closed container is slid into the cubicle, the switchgear and the line side terminal of the lightning arrester are brought into contact, and the cubicle and the lightning arrester flange are joined. Therefore, electrical circuits such as switchgear, terminal on the line side, and arrester element are formed. In this state, a double seal structure is formed by the shaft seal material arranged in the cylindrical portion and the face seal material arranged in the flange portion, and the airtightness of the SF 6 gas in the cubicle is reliably maintained.
【００１１】[0011]
以下に本考案の一実施例を図１及び図２を参照して説明する。 An embodiment of the present invention will be described below with reference to FIGS.
【００１２】 避雷器の密閉容器10はエポキシ樹脂を一体注型したもので、キュービクル９内 に収納されている円筒部10ａと、キュービクル９に避雷器を固定するフランジ部 10ｂとを備えている。円筒部10ａには必要に応じて機械加工を施し、テーパをつ けないフラット仕上げとする。この円筒部10ａの先端には開閉装置側の端子11と 着脱可能な線路側端子12が配設され、この線路側端子12と電気的に接続されてい る素子柱３が図２に示すように１柱構造にて円筒部10ａ内に収納されている。円 筒部10ａとキュービクル９の接触面には、キュービクル９に溝を形成し軸シール 材として、例えばスラスト用オイルシール13を配設する。またフランジ部10ｂと キュービクル９の接触面には、キュービクル９にオーリング溝を形成し、面シー ル材として面シール用パッキング14を配設する。密閉容器10とキュービクル９は フランジ部10ｂを貫通する複数の避雷器固定用ボルト15によって接合されている 。円筒部10ａには摺動を容易にし、ガス気密をさらに確実に保っため、グリース 16を塗布する。キュービクル９内にはＳＦ6 ガスが充填され、一方密閉容器10内 にはＮ2 ガスが充填されている。 次に作用について説明する。The lightning arrester closed container 10 is integrally cast with epoxy resin, and is provided with a cylindrical portion 10 a housed in the cubicle 9 and a flange portion 10 b for fixing the lightning arrester to the cubicle 9. The cylindrical portion 10a is machined as necessary to have a flat finish without taper. At the tip of the cylindrical portion 10a, a terminal 11 on the switchgear side and a line side terminal 12 which can be attached and detached are arranged, and the element column 3 electrically connected to the line side terminal 12 is arranged as shown in FIG. It has a one-column structure and is housed in the cylindrical portion 10a. On the contact surface between the cylindrical portion 10a and the cubicle 9, a groove is formed in the cubicle 9 and, for example, a thrust oil seal 13 is provided as a shaft sealing material. On the contact surface between the flange portion 10b and the cubicle 9, an O-ring groove is formed in the cubicle 9, and a face seal packing 14 is provided as a face seal material. The closed container 10 and the cubicle 9 are joined by a plurality of lightning arrester fixing bolts 15 penetrating the flange portion 10b. Grease 16 is applied to the cylindrical portion 10a in order to facilitate sliding and to further ensure gas tightness. The cubicle 9 is filled with SF 6 gas, while the closed container 10 is filled with N 2 gas. Next, the operation will be described.
【００１３】 上記の避雷器を投入状態から断路状態にするためには、まずボルト14をはずし 図１に示すように避雷器のフランジ部10ｂを例えば、あらかじめ持ち上げ状態に しておいたジャッキ17に固定する。このジャッキ17を下げると密閉容器10ごと避 雷器が下方へ摺動し、開閉装置側端子11と避雷器の線路側端子12が離れ、断路状 態となる。避雷器の駆動装置はジャッキ17に限らず、また手動装置、自動装置の いずれでもよい。避雷器を投入状態にするためには上記操作を逆の順に行う。 本実施例の避雷器によれば以下のような効果を奏する。 １．避雷器が小型化する。In order to change the above described arrester from the closed state to the disconnected state, first, the bolt 14 is removed, and as shown in FIG. 1, the flange portion 10b of the arrester is fixed to, for example, the jack 17 that has been lifted in advance. .. When the jack 17 is lowered, the lightning arrester together with the closed container 10 slides downward, the switchgear side terminal 11 and the liner side terminal 12 of the lightning arrester are separated, and a disconnection state is established. The drive device for the arrester is not limited to the jack 17, and may be a manual device or an automatic device. To turn on the arrester, repeat the above steps in reverse order. The lightning arrester of this embodiment has the following effects. 1. The lightning arrestor becomes smaller.
【００１４】 避雷器を密閉容器10ごと摺動させる断路方式としたため避雷器内部に電極間距 離を保つための余分な空間をあける必要がなく、避雷器の縦方向の長さがおさえ られる。このため素子を複数の柱に分割して積層する必要がなく、単純な一柱構 造にでき、円筒部10ａを径を小さく細くすることが可能になる。 ２．避雷器が軽量化する。 上記のように小型で単純構成となるため部品点数が大幅に削減され軽量化が達 成される。 ３．避雷器組立時の作業性が向上する。 ４．３相同時の断路、投入が可能となる。 避雷器の小型軽量化が達成されるため３相同時の操作が可能になり、操作時の 作業性も向上する。 ５．避雷器単体の輸送が容易になる。 密閉容器10内に素子柱３を収納したまま輸送することができ、輸送中水分等に さらされて素子が劣化する心配がない。 ６．万一避雷器が事故に至ってもキュービクル内の装置に影響しない。 ７．安価な避雷器を提供できる。Since the lightning arrester is of a disconnecting type in which the lightning arrester is slid together with the closed vessel 10, it is not necessary to provide an extra space inside the lightning arrester for keeping the distance between the electrodes, and the length of the lightning arrester in the vertical direction can be suppressed. For this reason, it is not necessary to divide the element into a plurality of pillars and stack them, a simple one-column structure can be obtained, and the diameter of the cylindrical portion 10a can be made small and thin. 2. The lightning arrestor is lightened. As described above, the small size and simple structure significantly reduce the number of parts and achieve weight reduction. 3. Workability at the time of assembling the lightning arrester is improved. 4.3 It is possible to disconnect and turn on three phases simultaneously. Since the lightning arrestor is made smaller and lighter, it is possible to operate three phases at the same time and the workability during operation is also improved. 5. It becomes easy to transport the lightning arrester alone. The element column 3 can be transported while being housed in the closed container 10, and there is no concern that the element will be deteriorated due to exposure to moisture or the like during transportation. 6. Should the lightning arrester lead to an accident, it will not affect the equipment inside the cubicle. 7. An inexpensive lightning arrester can be provided.
【００１５】 避雷器内とキュービクル９内はガス区分を異にし、密閉容器10内にはＮ2 ガス が充填されているので、密閉容器10内の絶縁板等に高価な耐ＳＦ6 ガス被膜を施 す必要がない。Since the lightning arrester and the cubicle 9 have different gas divisions and the closed container 10 is filled with N 2 gas, an expensive SF 6 gas resistant film is applied to the insulating plate and the like in the closed container 10. There is no need to do it.
【００１６】[0016]
以上のように本考案の避雷器は密閉容器ごと摺動することによって断路、投入 を行うので、避雷器を小型軽量化でき断路操作時の作業性が向上する。 As described above, the lightning arrester of the present invention disconnects and turns on by sliding together with the closed container, so that the lightning arrestor can be made smaller and lighter and the workability during disconnection operation is improved.
