|20140319100||ARC ENERGY ABSORBER - A device for cooling exhaust gases caused by an electrical arc in high or medium voltage switch gear, which device comprises a housing with an inlet and an outlet for passage of the gases, wherein a hydrous mineral is arranged in the housing for cooling the gases with the water contained in the hydrous mineral.||10-30-2014|
|20140284192||DRIVING ROD FOR MEDIUM VOLTAGE SWITCHING ELEMENT GEAR - A device for medium or high voltage switching element gear, the device having: a switching element for connecting two conductors: and a driving rod for operating the switch, wherein the driving rod comprises at least a surface layer of an electrically high resistance material. The electrically high resistance material ensures that a small current will flow through the material due to the present electrical field. This small current will cause a heating of the driving rod, such that condensation is reduced or prevented.||09-25-2014|
|20140247536||SWITCHING INSTALLATION WITH PRESSURE CONTROLLED SHORT-CIRCUIT DEVICE - A switching installation includes a gas tight housing with at least one wall part. An input conductor disposed in the housing is configured to carry an input voltage. An insulation is arranged around the input conductor so as to insulate the input conductor from the housing. A short-circuit device is changeable from a first condition, in which the insulation is insulating the input conductor from the housing, to a second condition, in which an electrical short circuit connection is created through the insulation between the input conductor and an auxiliary connection. An actuator is coupled to the at least one wall part of the gas tight housing and is configured to actuate the short-circuit device as a result of movement of the wall part caused by a pressure increase in the housing. A threshold device is configured to provide a preset threshold in the actuator.||09-04-2014|
|20130307648||ELECTROMAGNETIC ACTUATOR WITH UNDER VOLTAGE RELEASE - An electromagnetic actuator has a yoke for guiding a magnetic flux, and a holding plate attached to an actuating member, the holding plate and yoke forming a first magnetic circuit. Furthermore a magnetic flux generation device is provided for generating a magnetic flux in the first magnetic circuit.
