この発明は電気装置特に、大電流用すり接触装置に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to electrical devices, and more particularly to high current sliding contact devices.
電気エネルギーの伝送・分配に用いられる多くの装置に
はすり接触通電部材が必要である。Many devices used to transmit and distribute electrical energy require sliding contact current-carrying members.
このような装置にはたとえば、ガス絶縁型あるいは空気
絶縁型の断路器、接地開閉器、大電流母線開閉器、ガス
絶縁送電母線継手がある。Such devices include, for example, gas-insulated or air-insulated disconnectors, earthing switches, high-current busbar switches, and gas-insulated power transmission busbar joints.
これらの装置は、物理的に分離される開路位置と、機械

置との間に相対的に動くようになった二つの部材を備え
ている。These devices include two members adapted to move relative to each other between an open position where they are physically separated and a closed position where they are in mechanical contact and allow the flow of electrical energy.
これらの装置のすべてにおいて解決を要する問題は前記
二つの部材が機械的に接触した点における電気抵抗を減
少させることである。The problem that needs to be solved in all of these devices is to reduce the electrical resistance at the point of mechanical contact between the two parts.
この抵抗は電流が通るときジュール熱効果を生じ、これ
によって安全に伝送され得る電流の最大量が制限される
。This resistance creates a Joule heating effect when current is passed through it, which limits the maximum amount of current that can be safely transmitted.
この抵抗を減少させる多くの方法に、前記離接する二つ
の部材間に多数の別々の接点を設け、この二つの部材を
一緒にしようとする接触圧を与える方法がある。A number of ways to reduce this resistance include providing a number of separate contact points between the two separating members and applying a contact pressure that tends to bring the two members together.
接触圧を増し、かつ、二つの部材間の接触点の数を多く
することによって抵抗は少なくしても、この仕方はこれ
らの部材を開位置と閉位置との間で互いに移動させる機
構がかなりの力を発生しなければならないから、その機
構が高価になることを意味する。Although the resistance is reduced by increasing the contact pressure and increasing the number of contact points between the two members, this method requires a significant amount of the mechanism for moving these members relative to each other between the open and closed positions. This means that the mechanism is expensive because it has to generate a force of .

このような従来の装置では、接触抵抗と温度上昇とは許
容範囲内にあるが前記多くの接点を操作する力が必要な
ため、高価な大きいエネルギーを消費する操作機構が必
要となり、あるいは費用の点で好ましくなかった。In such conventional devices, the contact resistance and temperature rise are within acceptable limits, but the force required to operate the many contacts requires expensive, energy-consuming operating mechanisms, or I didn't like it in that respect.
そこで、安価で最小の接触抵抗を示す接触装置を得るこ
とが望ましい。It is therefore desirable to have a contact device that is inexpensive and exhibits minimal contact resistance.

There is a device attached to said housing for actuating the device, each of these spring forces having a radial component and a larger axial component, the radial component being applied to each contact finger. The spring force creates a contact pressure between the cylindrical conductor in combination with the cylindrical conductor, and the axial component creates a contact pressure between the contact fingers and the housing surface. having a line of action parallel to the direction of relative motion of the contact fingers to press the contact fingers against the surface of the housing and create electrical contact therebetween.
接触フィンガとハウジングの表面との接触点はばね力の
作用線からはずれている。The point of contact between the contact finger and the surface of the housing is out of the line of action of the spring force.
それ故、このばね力は中心の導体とハウジングとの相対
運動の方向に平行な成分と、この相対運動の方向に垂直
な成分とに分解される。This spring force is therefore resolved into a component parallel to the direction of relative movement between the central conductor and the housing and a component perpendicular to the direction of this relative movement.

っている。Effect 3 This contact device has a continuous current of 4,000 amperes and a
It has the ability to carry a symmetrical fault current of 3,000 amperes.
保持環24のみぞ22の側壁54と56とはコイルばね
20の中心線に対して所定の角度で傾いている。The side walls 54 and 56 of the groove 22 of the retaining ring 24 are inclined at a predetermined angle with respect to the centerline of the coil spring 20.
これによって二つの重要な利点が得られる。This provides two important advantages.
第1に、下側の角F(第3A図)によって接触装置の組
立てが容易になる。First, the lower corner F (FIG. 3A) facilitates assembly of the contact device.
上側の角Cによって、中心導体12が接触フィンガ18
から離脱するとき、コイルばね20が僅かに曲がり、接
触フィンガ18の先端が中心へ移動することができる。The upper corner C allows the center conductor 12 to be connected to the contact finger 18
When released from the coil spring 20, the coil spring 20 bends slightly, allowing the tip of the contact finger 18 to move towards the center.
保持環24の内径は中心導体12の外径より僅かに大き
い。The inner diameter of the retaining ring 24 is slightly larger than the outer diameter of the center conductor 12.
作用効果 4
そこで、中心導体12と外装接触装置14とはそれらの
間に僅かの中心ずれがあるときだけでなく、それらの軸
線間にいくらかの不平行性が存在しても正しい接触が得
られる。Effect 4: Therefore, correct contact can be obtained between the center conductor 12 and the outer contact device 14 not only when there is a slight center deviation between them, but also when there is some non-parallelism between their axes. .
このような動作ができるのはみぞ22の傾斜壁54によ
って接触フィンガ18が中心方向へ動くからである。This movement is possible because the inclined walls 54 of the grooves 22 cause the contact fingers 18 to move toward the center.
たとえば、角Gが13°に等しいとき、中心導体12と
外装接触装置14との両軸線の相互の傾きは3°まで可
能である。For example, when the angle G is equal to 13°, the mutual inclination of the axes of the central conductor 12 and the outer contact device 14 by up to 3° is possible.
これらの条件の下で正しい動作ができることは、軸線の
ずれが成分要素の調整によって比較的に容易に修正でき
るのにたいして、軸の相互の傾きを修正するのは極めて
困難であるという理由で、ことに重要である。Correct operation under these conditions is possible because, while misalignment of the axes can be corrected relatively easily by adjusting the component elements, it is extremely difficult to correct the mutual inclination of the axes. is important.
作用効果 5
ここで開示された形の接触フィンガ18を利用すると、
接触装置10の動作中に、点52,42゜44において
ぬぐい作用が生じる。Advantage 5 Utilizing the contact finger 18 of the form disclosed herein:

いし、あるいは、焼結と鋳造および導電率を増すための
焼鈍を含む3段作業で作ることもできる。The individual contact fingers 18 may be made in a precision blanking operation or in a three step operation including sintering, casting and annealing to increase conductivity.
ここに開示される装置によると、従来の技術によって同
じ費用で作られる装置に比べて、中心導体12と外装接
触装置14との間にほとんど2倍の接触点を使用するこ
とができる。With the device disclosed herein, nearly twice as many contact points can be used between the center conductor 12 and the outer contact device 14 as compared to devices made by conventional techniques and at the same cost.
従って性能が相当、向上し、接触フィンガ18と中心導
体12との間の全接触圧が少なくなることになる。The performance is therefore considerably improved and the total contact pressure between the contact fingers 18 and the center conductor 12 is reduced.
このことによりて、中心導体12の操作に安価な操作機
構を使用することができる。This allows the use of an inexpensive operating mechanism for operating the center conductor 12.
