  • Patent number: 4670632
    Abstract: The high-voltage switch with a closing resistor has a main switch point and, parallel to this, an auxiliary switch point, the closing resistor (19) being in series with the auxiliary switch point. A movable contact (17) of the auxiliary switch point is driven via a thrust-crank drive (16), in such a way that it closes before the main switch point and opens again after the main switch point has closed.In this high-voltage switch, the object is to achieve a cycle of movement which, while ensuring a saving of components of the drive, can be adapted in a simple way to differing network conditions.This is achieved because the thrust-crank drive (16) has a compressible joint (23), and because the movable contact (17) is coupled to two impact rings (34, 35) which interact with two stops (36, 37).

  • Patent number: 4608470
    Abstract: Between a fixed contact member (2) having a rated-current contact and a fixed arcing contact (3) which acts in conjunction with a moving contact member (4) having a moving rated-current contact (5) and moving arcing contact (6), and a first flange (7) an insertion resistance (8) is arranged.In order to save a further pair of contacts, the rated-current contact of the fixed contact member (2) is constructed as a sliding rated-current contact (14) which can be displaced in the switching-on direction by the moving contact member (4). During the switching-on process, it is first contacted by the moving rated-current contact (5) which creates a current path including a resistance contact (9) and the insertion resistance (8). A little later, the insertion resistance (8) is bridged when the moving arcing contact (6) comes into contact with the fixed arcing contact (3), which is connected to the first flange (7) by means of a conductor (20).
