【発明の詳細な説明】
〔産業上の利用分野〕
この発明は、絶縁媒体として絶縁ガスを封入したガス封
入容器の中の遮断器の主接点に人と切の動作を伝達する
ために、容器を貫通して往復運動をする動作棒と容器と
の間からガスが漏れるのを防止するガス絶縁開閉装置の
気密装置に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for transmitting a human disconnection action to the main contact of a circuit breaker in a gas-filled container filled with an insulating gas as an insulating medium. The present invention relates to an airtight device for a gas insulated switchgear that prevents gas from leaking between a container and an operating rod that reciprocates through the container.
従来、ガスシーリング方法には固定用、運動用、回転用
など種々の用途に０リングを使用することが一般的であ
り、ガス封入容器と遮断器の動作捧との摺動部にも運動
用の０リングを使用していた。Conventionally, in gas sealing methods, it has been common to use O-rings for various purposes such as fixed, moving, and rotating. I was using the 0 ring.
その際、必要に応じてＯリングの材質、形状を選定して
使用しており、またＯリングの二重装備・溝加工の工夫
もなされている。At that time, the material and shape of the O-ring are selected and used as necessary, and the O-ring is double-equipped and grooved.
前記の従来のＯリングによるガスシーリングは、Ｏリン
グのほとんどが合戒ゴム又はこれに類似した弾性物質を
材料としているために、耐腐食性、耐摩耗性、耐候性等
を考慮した上で使用するが、０リングは摺動部材である
ために組込み時の取扱い方や経年劣化、動作耐用回数（
ＪＥＣ規格では１万回以上〉等信頼性の点で問題があっ
た。Gas sealing using conventional O-rings as described above requires consideration of corrosion resistance, abrasion resistance, weather resistance, etc., as most O-rings are made of rubber or a similar elastic material. However, since the O-ring is a sliding member, there are issues with how it is handled during assembly, deterioration over time, and the number of operating lifespans (
According to the JEC standard, there were problems with reliability, such as 10,000 times or more.
特に、０リングの摩耗の度合、損傷、寿命についての正
確な状態を外部から判断することが困ｘｔｔであり、よ
り一層信頼性に問題があった。ガス漏れが生じると装置
の機能低下を引き起こし、最悪の場合、事故につながる
恐れもある。In particular, it is difficult to accurately determine the degree of wear, damage, and life of the O-ring from the outside, which further poses a problem in reliability. If a gas leak occurs, the functionality of the equipment will deteriorate, and in the worst case, it may lead to an accident.
この発明の目的は、ガス封入容器とこの容器を貫通して
往復運動をする動作棒との間の気密保持をより確実にす
ることを目的とする。An object of the present invention is to more reliably maintain airtightness between a gas-filled container and an operating rod that reciprocates through the container.
この発明のガス絶縁開閉装置の気密装置は、ガス絶縁開
閉装置のガス封入容器とこのガス封入容器を貫通し軸方

一端を前記動作棒に、他端を前記ガス封入容器に固着す
るものである。The airtight device of the gas insulated switchgear of the present invention has a cylindrical or holed structure between the gas-filled container of the gas-insulated switchgear and the operating rod of the circuit breaker that penetrates the gas-filled container and reciprocates in the axial direction. A flexible thin film material having a plate shape is arranged, and one end of the thin film material is fixed to the operating rod and the other end is fixed to the gas filled container.

ガイドされる。Since the space between the gas-filled container and the operating rod is made airtight with a flexible thin film material such as a bellows, there are no sliding parts even if the operating rod is allowed to reciprocate. [Embodiment] FIG. 1 shows a cross-sectional view of an embodiment, in which a lever support 5 is attached to a flange portion 2a of a gas-filled container 2 filled with an insulating gas 1 by a fixing O-ring 3a and a bolt 4a. . An operating rod 6 of the circuit breaker (not shown) is guided through the penetrating portion inside the lever support 5 through a small gap, and is reciprocated up and down via an operating lever 7 from the outside to operate the circuit breaker. Turn on or off. A support member 8 having a convex portion 8a is attached to the container side of the lever support 5 by a fixing O-ring 3b and a bolt 4b, and the operating rod is connected to the inner penetrating portion of the support member 8 through a slight gap. 6 is guided through it.

、例えばプラズマ溶接で固着される。The upper and lower ends of the metal cylindrical bellows 9 are airtightly connected to the convex portion 8a of the mounting member 8 and the operating rod 6 through mounting pieces 10 (10a, 10b) each having a U-shaped cross section. For example, it is fixed by plasma welding.

、筒状ならば軸方向にスペースをとり、径方向にスペー
スをとらず、板状ならその反対である。The bellows 9 is of a known type that can withstand expansion and contraction many times in the axial direction. In addition, a thin metal plate with concentric pleats such as those used in an aneroid barometer may be used, a thin rubber plate may be used as long as the outer diameter is large enough for the stroke of the operating rod, or a cylindrical rubber plate may be used. These bellows, metal plates with concentric pleats, flexible thin films with large diameters, and cylindrical rubber are all ``cylindrical or plate-shaped flexible thin film materials'' described in the means section. ”. If the thin film material is cylindrical, it will take up space in the axial direction, but not in the radial direction, and vice versa if it is plate-shaped.
なお、動作棒６・はレバー支え５の内側及び支持材８の
内側とわずかな隙間を介して貫通してガイドされると説
明したが、これは気密には直接関係せず、容器側に対し
動作棒の同心性とたおれを少なくして薄膜材に無理な力

適用するとよい。It has been explained that the operating rod 6 is guided through a small gap between the inside of the lever support 5 and the inside of the support member 8, but this is not directly related to airtightness and is guided through the inside of the lever support 5 and the inside of the support member 8. This is to reduce the concentricity and sag of the operating rod to avoid applying excessive force to the thin film material, and it is recommended to apply grease or the like to the gap.

スの漏れに対する信頼性が向上するという効果がある。The airtight device for a gas-insulated switchgear of the present invention has a cylindrical or plate-like hole with holes between a gas-filled container of the gas-insulated switchgear and an operating rod of a circuit breaker that penetrates the gas-filled container and reciprocates in the axial direction. A flexible thin film material is arranged in the same direction, and one end of the thin film material is fixed to the operating rod and the other end is fixed to the gas-filled container, so that the operating rod can penetrate through the gas-filled container and move the operating rod in the axial direction. Despite the reciprocating motion, the thin film material maintains a complete air seal without any sliding parts, eliminates the wear caused by sliding like conventional O-rings, and has the effect of improving reliability against gas leaks. be.
