摘要： PCT No. PCT/DE92/00785 Sec. 371 Date May 25, 1994 Sec. 102(e) Date May 25, 1994 PCT Filed Jun. 11, 1992 PCT Pub. No. WO93/07635 PCT Pub. Date Apr. 15, 1993.A multi-pole vacuum switch which has, for each vacuum switching tube, a pole operating unit with a lever arrangement for changing the direction of movement produced by a drive device. Two toggle levers are arranged in a casing of the pole operating unit. A first toggle lever is connected to the operating plunger of the vacuum switching tube and the second toggle lever is connected to a supporting lever. The supporting lever acts on a contact pressure spring via a pull rod. In the switched-on position (where the switch is closed), the first and second toggle levers are close to dead center. An adjustment device permits the toggle levers to be adjusted relative to the supporting lever.

摘要： The drive mechanism of a vacuum interrupter (1) has a two-armed lever (7), supported such that it can pivot, and a spring (11) which engages on the lever and provides the contact force. The two-armed lever (7) is guided in its bearing (oblong hole 9, pivot pin 8) such that it can move in a limited manner in a direction running approximately parallel to the direction of operation of the interrupter (1). On switching on, the two-armed lever (7), with its pivot pin (8), pivots about the end of the pin guide until the switching pieces (3, 5) make contact. Further pivoting of the lever (7) takes place about a hinge arrangement (6) between the two-armed lever (7) and the drive ram (4). The two-armed lever (7) can be formed from two parallel partial levers (20) at such a spacing that the spring (11) can engage between the partial levers. The drive mechanism is suitable for single or multipin vacuum power circuit breakers, for example for use in gas-insulated switching installations. … …

摘要： Multi-pole vacuum switch with a pole operating unit for each vacuum switching tube A multi-pole vacuum switch (1) has, for each vacuum switching tube (10), a pole operating unit (5) with a lever arrangement for changing the direction of movement produced by a drive device (3). In a casing (16) of the pole operating unit (5), two toggle levers (21, 22) are arranged, one (21) of which is connected to the operating plunger (12) of the vacuum switching tube (10) and the other of which is connected to a supporting lever (25) which acts on a contact pressure spring (32) via a pull rod (30). In the switched-on position, the toggle levers (21, 22) are close to dead centre. An adjustment device (40, 42) permits the toggle levers (21, 22) to be adjusted in relation to the supporting lever (25). FIG 2

摘要： A vacuum circuit breaker (1) having two switching tubes (5) which are electrically connected in series and aligned coaxially. By means of an offset drive unit (toggle lever system 26) two motions that are contrary to one another are produced for the drive tappets (15) of the breaker tubes (5), from the common drive motion of a rod (11). The contact pressure springs (32) of the two switching tubes (5) are directly or indirectly connected to a common stationary support (35) which can be unfastened and moved to a new position. Simultaneous contacting or separation of the breaker elements of the two breaker tubes produced by the common drive is ensured by loosening the bearing block, after releasing the connection with the common drive mechanism, and fastening it again after the force differential has been automatically compensated for. The invention is suitable for vacuum circuit breakers in the medium-voltage range, such as those used to supply power to railroads.

摘要： The combined current and voltage measuring apparatus has a cast resin body which supports the current measuring unit. The voltage measuring unit includes a capacitive voltage divider with an amplifier connected thereto. The cast resin body is also utilized as dielectric for the capacitor on the high-voltage side of the capacitive voltage divider. Embedded in the cast resin body is an auxiliary capacitor with a dielectric which, with respect to temperature dependence, corresponds to the dielectric of the high-voltage capacitor. The auxiliary capacitor, in series with a resistor, is connected to an auxiliary generator. The voltage dropped across the resistor is supplied, after rectification, to an input of a differential amplifier; the other input of the differential amplifier is connected to the terminal away from ground of the capacitor on the low-voltage side of the capacitive voltage divider. With respect to the capacitors of the capacitive voltage divider, a warming of the capacitor on the high-voltage side different from the warming of the capacitor on the low-voltage side does not influence the measuring accuracy of the capacitive voltage measuring unit of the apparatus.

摘要： A vacuum switching apparatus is equipped with a switching vessel which can be actuated by a drive unit at ground potential by means of a drive assembly transmitting the drive motion. The drive assembly includes a lever made of insulating material which is fulcrumed about an electrically conductive bearing pin. The lever serves as the actuating member of the switching vessel and the bearing pin is at an intermediate potential between the grounded and the high-voltage-carrying parts.
