[Detailed description of the invention] [Technical field to which the invention pertains] The present invention includes two relatively movable contact holders, and forms a contact system in which these contact holders are separated by electromagnetic force. One of these concerns a high-speed shear breaker rotatably supported by a bearing on a contact shaft within a holder support frame connected to an opening/closing mechanism via an opening/closing shaft.

In switching devices of this type, which generally have mechanically driven contact holders, the force of the contact spring creates the contact pressure necessary to provide an appropriately low contact resistance. In current-limiting type circuit breakers, it is desired that, on the one hand, the contact pressure is sufficient for the rated current, and on the other hand, that the contact springs do not excessively impede the high-speed opening movement caused by electromagnetic force.

Equipped with a contact system that opens and opens by electromagnetic force, this contact system consists of two contact holders that are approximately parallel and relatively movable, one of which is connected to a lever mechanism and can be rotated by an opening/closing shaft. High speed shear disconnectors are known which are supported in bearings on the contact holder and are provided with contact springs in such a way that a clockwise moment is exerted on the contact holder about the contact axis. The lever mechanism is coupled to the overcurrent trip device via a latched trip mechanism. The current flowing through both contact holders creates an electromagnetic force that acts on the contact holder with the contact spring and tends to turn it. The current circuit and the contact springs are designed in such a way that rotation only occurs when the current reaches a certain predetermined value, ie a set limit value of the electromagnetic force. Contact pressure is applied to spring ladders and disconnectors during rated operation. When a short-circuit current exceeding the limit value of the electromagnetic force flows, the contact holder begins to rotate around the contact axis under the action of the electromagnetic force against the contact spring force until it finally hits the stopper. At this time, the contact holder opens before the overcurrent trip device responds,
The generated arc prevents an increase in short circuit current.
In this unstable position of the contact holder, both ends of the contact spring and the axis of the contact shaft are located on a straight line, so that the force of the contact spring is completely received by the contact shaft. To prevent the point shaft holder from rotating counterclockwise around the contact shaft beyond this unstable position,
Appropriate stoppers are provided (West German Patent Application No. 2928823). Therefore, the electromagnetic force must constantly rotate the contact holder against the force of the contact spring, resulting in a disadvantage that the opening of the contacts is delayed.

The present invention is such that the contact spring force that prevents high-speed automatic opening no longer acts against the opening movement of the contact holder after a short opening stroke, and preferably the component force of the contact spring acts in reverse. The purpose is to improve high-speed breaker.

This is achieved by Due to the cam plate, the projection line of the cam part making an acute angle with the long axis of the contact holder, as soon as the pin reaches the end of the cam part after a short opening stroke due to rotation of the cam plate,
The contact pressure, which prevents the contact from opening, is at least significantly weakened.

The current flowing through both contact holders 2 and 4 generates an electromagnetic force that acts on the contact holders and tends to turn them. The electrical circuit and contact springs are designed such that rotation occurs only when the current reaches a predetermined value. As soon as the current exceeds this value, the contact holder 4 begins to pivot around the switching axis 10 under the action of electromagnetic forces. The contact spring force provides a rotational moment that opposes the opening movement of the contact holder 4 until the pin 22 reaches the corner 20 on the cam part 16. Beyond corner 20, the rotational moment of the contact spring force suddenly changes. This sudden change in rotational moment causes the second cam portion 18 to
It is determined by the shape of In the first embodiment shown in FIG. 1, the second cam portion is a circular arc passing through the projection point of the corner 20 and having the connecting line 30 as its radius, so that the rotational moment of the contact spring force is zero.
Due to this configuration of the cam plates 12 and 14 and the guide slot 28, the contact spring force is interrupted after a small opening stroke of the contact holder corresponding to the angle of rotation.

In FIG. 3, which shows the second embodiment, the projection line of the second cam part 18 forms an acute angle γ with the long axis of the contact holder 4, which opens toward the contact axis 10. In FIG. This shape changes the direction of the rotational moment of the contact spring force when the pin 22 passes over the corner 20, causing an additional acceleration of the contact holder 4. However, the rotational moment of the contact spring force is

[Claims] 1. Comprising two relatively movable contact holders, these contact holders form a contact system that opens and opens by electromagnetic force, and one of these contact holders opens and closes via an opening and closing shaft. In a high-speed breaker supported by a holder support frame coupled to a mechanism, the one contact holder is rotatably supported by a bearing at a predetermined position of the holder support frame via a contact shaft, and the A cam plate is provided eccentrically in the range of the contact shaft, and the end face of the cam plate on the opening/closing shaft side is provided with a first cam part, and the projection line of this cam part on the drawing paper and the one contact holder are The long axis intersects with the contact axis at an acute angle that opens towards the contact axis. A high-speed shear disconnector characterized in that it is slidably guided in a guide slit of a holder support frame. 2. In the shear disconnector according to claim 1, each of the cam plates includes a second cam portion,
High-speed shingle disconnector, characterized in that a corner is provided in each case as a transition from the first cam part to the second cam part. 3 In the shear cutter according to claim 2, the projection line of the second cam portion is a connecting line between the corner and the axis of the contact shaft, and this connecting line is a radius, and the projected point of the corner is 1. A high-speed shingle breaker characterized in that it has an arbitrary continuous linear line disposed between circular arcs passing through it. 4. A high-speed shear cutter according to claim 2 or 3, characterized in that the projection line of the second cam portion is a circular arc. 5. In the cutter according to claim 2 or 3, the projection line of the second cam portion forms an acute angle with the long axis of one contact holder that opens toward the contact axis. A high-speed wire cutter characterized by its straight line. 6. In the cutter according to claim 2 or 3, the projection line of the second cam portion is a curved line having a radius that increases in the direction of rotation of one contact holder. Features a high speed breaker. 7. The cutter according to any one of claims 2 to 6, characterized in that the guide slit forms an acute angle with one contact holder that opens toward the opening/closing axis. High speed shiya disconnector. 8. A high-speed switch according to any one of claims 2 to 6, characterized in that the guide slit is arranged perpendicularly to the long axis of one contact holder. Disconnector. 9. A high-speed disconnector according to any one of claims 2 to 6, characterized in that the guide slit is arranged parallel to the long axis of one contact holder. Disconnector. 10 The shear cutter according to any one of claims 2 to 6, characterized in that the guide slit has an arc shape that is convex when viewed from the opening/closing axis of the opposing boundary wall. High-speed breaker.
