Definitions
- the guide gap provided in the link plate is designed in such a way that it extends to a long, rectilinear first region, which is used for quick opening and Closing the movable contact of the vacuum switch is used, a smaller, slightly angled further area of the guide gap connects, in which the bolt can engage, so to speak, in the closed position of the movable contact and thus holds the movable contact securely in its closed position. Furthermore, this further area serves to reduce the speed of the movable contact shortly before the closing, so that a rebounding of the movable contact from a stationary contact when closing can be largely prevented.
- the first guide area has a steeper course than the second guide area.
- the first and / or the second guide region have a curved course. This enables the path-time characteristic to be more precise be adapted to a required course. For example, the speed of the movable contact can be further reduced shortly before the closing by a correspondingly curved course of the second guide region.
- the first and second guide areas each have a linear course.
- the guide areas are designed with a linear, that is to say a straight, course, a particularly simple manufacture of the link plate of the adjusting device can be achieved.
- the bolt is arranged to be guided by two guide disks of the same design and arranged parallel to one another.
- the bolt can be guided in a particularly simple manner and, if necessary, the bolt can not jam during the opening or closing movement.
- FIG. 1 schematically shows an adjusting device 1 for adjusting a movable contact 2a of a switching device, also shown only schematically, in the form of a vacuum circuit breaker 3.
- a coupling device (not shown in FIG. 1) in the form of a coupling rod 4
- two link plates 5 and 6 arranged parallel to each other are moved.
- the coupling rod 4 is pivotally connected to the link plates 5 and 6 at a connection point 14, for example by means of an axis running between the two link plates 5, 6.
- the link disks 5, 6 are also rotatably connected at their lower end at a fixed pivot point 16, for example to a housing part of a housing enclosing the adjusting device 1.
- FIG. 1 schematically shows an adjusting device 1 for adjusting a movable contact 2a of a switching device, also shown only schematically, in the form of a vacuum circuit breaker 3.
- a coupling device (not shown in FIG. 1) in the form of a coupling rod 4
- the coupling rod 4 is pivot
- the link plate 5 is shown broken away shortly in front of the coupling rod 4 in order to reveal the view of the coupling rod 4 and the further link plate 6 lying behind the link plate 5.
- the link plates 5 and 6 each have a guide gap 7 according to FIG. 1, this guide gap 7 consisting of three adjacent sections 7a, 7b and 7c.
- a first guide area 7a of the guide gap 7 is provided, this first guide area 7a extending obliquely with respect to a so-called intermediate area 7b adjacent to it.
- the intermediate region 7b runs in the horizontal direction, that is to say without any slope.
- a second guide area 7c adjoins this intermediate area 7b, which in turn has an oblique course with respect to the intermediate area 7b.
- the bolt 8 guided by the link washers is in turn connected to a drive rod 9 which is connected at its other end to the movable contact 2a of the vacuum switch 35.
- the drive rod 9 is guided, for example, by means of a bellows 10 into a housing 11 of the vacuum switch 3.
- a holding rod 12 is connected to the bolt 8, which is intended to prevent 10 a movement of the bolt 8 transversely to the adjustment direction of the movable contact 2a.
- the holding rod 12 is of a correspondingly long design, so that the circular arc around the pivot point 19, on which the bolt 8 executes its movement, can be regarded approximately as a straight line.
