、このスリ、トは接点支持体をセグメントに分割する。The coaxially arranged collar-shaped contacts each form a rotating body, the bottom of which is connected to the conductor and the edge of the collar forming a ring-shaped contact surface. The contact carrier of the solid contact is provided with oblique slits extending in opposite directions, the slits dividing the contact carrier into segments.

In the contact portion of the L-interrupter, the edge of the contact is provided with a collar-shaped outward protrusion, and the outer edge KM of the surface of the protrusion is rounded to the mating contact. The flat part on the front side of this collar contact forms the contact surface, and the beveled edge at 16 is the point where the arc is driven outward by the radial component of the output. A burnt area is formed. The pot-like contact may also include a collar-like inward projection;
The diagonal chamfer is used as a Vc burnout area once the arc foot point is driven inward from the contact surface.

リング状接点の中央部平面は接触面を形成する。The central plane of the ring-shaped contact forms a contact surface.

い焼損を生せしめることもある。For example, in the case of a high voltage of 36 kV or more, a large current of 50 kV or more, and a relatively long arc time, the arc foot point will reach the outer cylindrical surface of the contact support with a weight of 1%. It has been known. There, especially on the anode side, relatively unreasonable burnout of the carrier material, which generally consists primarily of steel, can occur. Although copper vapor diffuses relatively quickly and without stagnation, restriking cannot be completely avoided. Additionally, the pins may be driven radially inward and their feet may attach to the inner surface of the contact support, causing severe burnout of the support material there.

で移動するのを防止することを目的とする。The object of the present invention is to stabilize a 7-point foot point in front of ring-shaped contacts arranged opposite to each other, and to prevent the 7-point foot point from moving by its neck toward a contact support.

には接点の内縁又は外縁を越えて回り込重なければなら
ない。This object is achieved in the contact area of such a vacuum interrupter according to the invention in that the ring-shaped contact has a radially inwardly and outwardly directed boxwood projection. Since this projection projects beyond the end face of the contact carrier, the arc foot must wrap around beyond the inner or outer edge of the contact in order to attach to the contact carrier.

接点の接触面付近において安定化する。However, when the foot point approaches the edge of the ring-shaped contact, a magnetic component acts in the radial direction that prevents movement of the foot point beyond the edge of the ring-shaped contact. The arc is therefore stabilized near the contact surface of the II song contact.
