| 20100072045 | Switch Pole with a Mounting Frame Having Latching Means - A switch pole for interrupting an alternating electrical current has a supporting frame formed of insulating material. An interrupter extends in a longitudinal direction within the supporting frame between an input connection and an output connection and is configured to interrupt the alternating current between the input connection and the output connection. The input connection, the output connection, and the interrupter are held by the supporting frame. The insulating capacity of the supporting frame of the novel switch pole can be matched in a simple manner to the requirements placed respectively on the switch pole. For that purpose, the supporting frame has latching means for accommodating additional insulating parts, with which the insulating capacity of the supporting frame is increased. | 03-25-2010 |
| 20100078298 | Interlocking Lock for Preventing a Switch from Switching On - A locking mechanism in a switch in the field of electrical power distribution prevents an energy storage device from being discharged. The mechanism has a pushbutton which, when the locking mechanism is in an unlocked position, is coupled by way of a force transmission element via an interlocking connection to a discharge initiator for discharging of the energy storage device, such that a switching-on movement acting on the pushbutton is introduced via the force transmission element into the discharge initiator in order to relieve the load on a force storage device, with the force transmission element being connected to interlock interruption means for moving the locking mechanism to a locked position in which the interlock is cancelled. The pushbutton and the force transmission element are guided in the unlocked position to move in a common longitudinal direction, such that a pushing movement of the pushbutton is introduced into the switching-on initiator via a longitudinal movement of the force transmission element. The locking mechanism is mechanically compact and operates reliably. The force transmission element is pivotally mounted such that, in a locked position, a movement direction of the force transmission element is aligned at an angle to the pushing movement of the pushbutton, with the interlock interruption means being coupled to a drive shaft of the switch and/or to an auxiliary switch. | 04-01-2010 |
| 20100078300 | Circuit Breaker - A circuit breaker has at least one pole arrangement with a movable contact. A twin-armed lever is pivotally mounted for opening and closing the movable contact. A switch-on energy storage device is provided and a cam disc that is coupled to the switch-on energy storage device and, via an actuating element, to a first end of the lever. The second end of the lever is connected to the movable contact piece of the pole arrangement. There is also provided at least one switch-off energy storage device. The circuit breaker has a simple and compact design. The actuating element is a switching shaft, which interacts with the cam disc, is mounted such that it can rotate and is connected to the first end of the twin-armed lever via the switch-off energy storage device. | 04-01-2010 |
| 20100089734 | Switch-on Energy Store Apparatus - In order to form a switch-on energy storage apparatus for a circuit breaker, wherein a switch-on energy storage device is held at a first end and is connected to a cam of a tensioning apparatus at a second end, with which tensioning apparatus means interact which limit a return movement. The switch-on energy storage apparatus has a simple and cost-effective design. The means have a ratchet mechanism arranged at the first end of the switch-on energy storage device. | 04-15-2010 |
