|20140327502||ELECTROMAGNETIC ACTUATOR - An electromagnetic actuator for operating at least one movable contact of a switch into a switched-on position or a switched-off position, the actuator having: a static pole body; a movable pole body movable relative to the static pole body; a first magnetic circuit with a first coil for making the movable pole body and the fixed pole body move towards each other to a switched-on position and a second coil for making the movable pole body and the fixed pole body move away from each other to a switched-off position; and a second magnetic circuit with a permanent magnet and a retaining plate to keep the static pole body and the movable pole body in the switched-on position; first spring unit for urging the static pole body and the movable body away from each other; wherein the first and second magnetic circuit are arranged concentrically.||11-06-2014|
|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. The magnetic flux generation device has an under voltage release coil electrically connected to an auxiliary voltage source representing the value of a voltage to be monitored.||11-21-2013|
|20130285773||DISCONNECTOR SWITCH FOR VOLTAGE TRANSFORMER - A disconnector unit for a medium voltage application, with a conductive pen inside a housing. The conductive pen is moveable between an operational position in which an electrical contact is provided between a first terminal and a second terminal positioned inside the housing, and an off position in which no electrical contact is present between the first terminal and the second terminal. The conductive pen includes a first actuating part inside the housing, optionally, in the form of a magnet. The disconnector unit further includes a second actuating part positioned outside the housing, wherein the first actuating part and second actuating part form a non-mechanical link.||10-31-2013|
|20130203295||CONNECTION ASSEMBLY FOR ELECTRICAL CABINET - A connection assembly for providing a plurality of connections to an interface block attached to a withdrawable unit in an electrical cabinet includes: an auxiliary contact block. the auxiliary contact block including: a first plurality of contact members for connection to the withdrawable unit; and attachment elements for attachment of the auxiliary contact block to a structural part of the electrical cabinet; and a connection block. the connection block including a plurality of contacts for providing wiring connections towards a cableway in the electrical cabinet. The connection block and the auxiliary contact block are separable.||08-08-2013|

|20130049904||TRIP UNIT - A trip unit includes an actuator and a cylindrical housing container the actuator. The actuator includes a cylindrical pin; a cylindrical closed chamber; a biasing member; a permanent magnet; a coil housing; and a coil supported by the coil housing. The pin is axially movably disposed in the chamber and extends out of the chamber through a sealed opening. The biasing member may comprise a spring, such as a helical spring, and may be configured to bias the pin for an axial movement in a direction out of the chamber. The permanent magnet may at least partly surround the pin during a latched condition of the trip unit. The coil housing may at least partly define the cylindrical closed chamber. In embodiments, an annular gap is provided between the pin and the permanent magnet. Methods associated with the manufacturing trip units are also disclosed.||02-28-2013|
|20130048478||SWITCH ARRANGEMENT FOR AN ELECTRICAL SWITCHGEAR - A switch arrangement for an electrical switchgear includes: a terminal arrangement including an insulating housing, the insulating housing including a first electrical contact and a second electrical contact which arc spaced apart along an axial direction; and a breaker moveable along the axial direction in the housing to a first position. When the breaker is in the first position and closed it electrically connects the first electrical contact and the second electrical contact. The insulating housing is split into a plurality of separate sections along the axial direction. At least one of the electrical contacts is in a first section and at least another of the electrical contacts is in a second section.||02-28-2013|
