摘要： A lever arrangement to transmit a driving force to a switch contact of a power switch has parallel bearing plates (43, 44) and limiters (51, 52) secured thereto by means of which the distance between the bearing plates is locally reduced to one suitable for guiding articulated levers. Hinge pins (54) of the levers are supported so as to slide on the limiters (51, 52). Threaded pins (46) are riveted on one side to one bearing plate (43) and secured to the other bearing plate (44) by a nut (50).

摘要： Described ia a multi-pole low-voltage power switch (1) designed with several switching chambers (3) per pole and a common switching shaft (2) which acts for the pole units (9) formed by the switching chambers (3). The switching shaft (2) is made up of shaft sections (21, 22, 23) which correspond to the pole units (9). While the central shaft section (21) has central pins (24) and levers (25), the peripheral shaft sections (22, 23) are fitted with levers (30) and have central apertures (27) in which the pins (24) engage. Bolts (35) which pass through the levers (25, 30) are used to couple the shaft sections (21, 22, 23) together. The pole units (9) rest on a support (20) which is dimensioned to accommodate the maximum width of the pole units (9) and to allow for possible variations in their dimensions. Side walls (4) of the correct dimensions for a pull-out rack (8) enclose the supporting framework (5) of the power switch (1) on each side.

摘要： The invention relates to a switch contact arrangement (8) comprising a contact support (10a), at least two switch contacts (11), and at least one spacer (28a). The switch contacts (11) are pivotally mounted on the contact support (10a) while being respectively provided with at least one associated terminal lead (21) that encompasses a flexible section (22). In order to reduce the driving forces required for the switching movements of the switch contacts (11), the at least one spacer (28a) engages between the flexible sections (22) of adjacent switch contacts (11).

摘要： The invention relates to a drive train for a displaceable contact (1) on a breaker contact arrangement in an electrical power breaker, whereby a coupling element (3), displaceable against a stop (12) and arranged between the moveable contact (1) and corresponding drive element (8), is provided with an anti-bounce device, comprising a catch element (13) and a counter piece (14). The catch element (13) which may be swung into a catch position as a result of the inertia exerted on the centre of gravity (16) thereof, when the coupling element (3) strikes the stop (12), comprises a working surface (22) extending in the pivoting direction (23) to form a momentary working connection with the counter piece (14). A retaining spring (32) is additionally provided on the catch element (13) to guarantee that a rebounding of the coupling element (3) into the position corresponding to the closed state of the breaker contact arrangement does not occur.

摘要： The invention relates to a device for controlling the closing of a power circuit breaker according to operational parameters. Said device comprises an indication element (13) for indicating the readiness for closing and a coupling element (27) which interacts with the indication element (13). The operational parameters, for example, energy store empty or switchgear cell door open cause the indication element (13) to pivot into the position not ready for closing and cause the coupling element (27) to move into its disabled position. The indication element (13) for indicating the readiness for closing and additional indication elements (46, 47), which represent the position of the switching contacts and the state of the energy store, are adjacently arranged in an axial manner such that they can pivot and are provided with interacting drives in order to effect a forced drive of the indication element (13) for indicating the readiness for closing when the position of the switching contacts (6) or the state of the energy store (1) does not enable or permit a closing of the power circuit breaker.

摘要： The invention relates to a low-voltage power switch with an actuating shaft for actuating switching contacts. The actuating shaft consists of a centre shaft with radially extending levers which can be connected to switching contacts or a drive unit. At least one section of the centre shaft (2) and one part of the levers (3) are produced as a single-piece actuating shaft unit according to a metal casting process. Preferably, the pressure casting process involves the use of aluminium or zinc alloys.

摘要： A power switch (1) with a contact device (2) and a switching mechanism (10) has a spring energy store (11) for storing drive energy for the switching mechanism (10). A deflecting element (17) which transmits the action of a further spring (15) in the direction of action of a first spring (14) is mounted on a fixed pivot bearing (16). The deflecting element (17) can be connected, by driving rods (21, 22, 24) of different lengths, to the first spring (14) either at its end (18) facing the pivot bearing (16) or at its end (19) facing away from the pivot bearing (16). This arrangement makes it possible to connect the springs (14, 15, 26) mechanically in series or in parallel without altering external dimensions.

摘要： A bearing arrangement for a switch shaft (1) of a multi-pole electric switching device with a chassis consisting of parallel walls (2, 3, 4, 5, 6) has shaft bearings with half-shells (7). The walls (2, 3) designed to take the shaft bearing have side apertures (11) having a limiting edge (12) with the radius and width of a groove (10) on the outer periphery of the half-shells (7) and another limiting edge (13) with the outside diameter of the half-shells (7). A locking member (14) to be secured to the appropriate wall (2, 3) secures the half-shells (7) on the switch shaft (1) after they have been fitted.
