| 5416266 | Encased gas-insulated high-tension installation and an assembly of such an installation The end flange (16) of the first encasing part (10) of the gas-insulated high-tension installation is an outer flange and includes through bores (34). A first securing ring (18) is provided on the end-face side of the end flange (16). The securing ring ho... | 05/16/1995 |
| 5358073 | Method and apparatus for tensioning an accumulator spring of a drive of a high-voltage or medium-voltage power circuit breaker A method and apparatus for tensioning the accumulator spring of a high-voltage or medium-voltage power circuit breaker drive, in which a drilling machine or a power tool, such as a screwdriver, which is powered by a rechargeable battery, is used.... | 10/25/1994 |
| 5304762 | Gas-blast circuit breaker The gas-blast circuit breaker has passages in the pump piston which connect the pump space to the arcing space surrounding the quenching tube and to the surrounding space located within the circuit breaker housing. These passages are held closed during sw... | 04/19/1994 |
| 5269055 | Method of assembling a circuit-breaker pole In the course of the assembly of a circuit-breaker pole, the individual parts of a housing are stacked loosely one on top of the other and fixedly positioned. This fixing can be accomplished by applying subatmospheric pressure or a partial vacuum within t... | 12/14/1993 |
| 5248862 | Gas-blast circuit breaker In a gas-blast circuit breaker, compressed gas is directed through a movable contact maker into a blow-out space, the latter being delimited by a cylinder and a piston which is operatively associated with the movable contact maker. The piston comprises in... | 09/28/1993 |
| 5128502 | Three-pole, gas-insulated switch arrangement A three-pole switch arrangement has for each pole a pole housing, onto which collar-shaped extensions, protruding on the underside, are formed. Provided in the extensions are screw holes, the graduation of which corresponds to the screw coupling, by which... | 07/07/1992 |
| 5113056 | Stored-spring-energy actuator mechanism for a high-voltage circuit breaker The stored-spring-energy actuator mechanism (210) for the high-voltage circuit breaker (218) has a spiral spring (216) which can be loaded by means of the loading device (212). The high-voltage circuit breaker (218) can be switched on once and off once wi... | 05/12/1992 |
| 5098318 | Electrical contact assembly An electrical contact assembly has a contact carrier formed with symmetrically opposed rows of comb-like guides, opposed rows of double-ended contact fingers mounted in the guides, a first contact piece supported by the contact carrier between the contact... | 03/24/1992 |
| 5091615 | Vacuum switch A housing of a vacuum switch has in an upper connecting region a passage, through which the connecting element is led. The latter engages with its end region in a recess, opposite the passage, in the housing. In the region of the passage, the connecting e... | 02/25/1992 |
| 5055640 | Multi-pin vacuum switch arrangement An insulating supporting frame of a multi-pin switch arrangement has a box-shaped base part and an insulating supporting part arranged over it. Insulating housings encompassing the vacuum switch tubes are formed onto a wall part. On the rear, bearing part... | 10/08/1991 |
| 4996397 | Spring-force drive for a power switch Two disks per vacuum switch tube are mounted on a drive shaft, the disks having grooves running around the drive shaft and open in relation to one another. In the grooves of two of these disks, a cylindrical follower is guided, the movement of which is tr... | 02/26/1991 |
| 4968861 | Actuator mechanism for a high-voltage circuit breaker In a stored-spring-energy type actuator mechanism for a high-voltage circuit breaker, energy is stored in a spiral spring in order to switch on the circuit breaker and also to load a switch-off spring of the circuit breaker. To store sufficient energy for... | 11/06/1990 |
