High-voltage switches with arc preventing or extinguishing devices inventions 06/06

20060138088 - Disconnecting switch assembly: The invention relates to a disconnecting switch assembly for disconnecting air-insulated electrical lines, which have one or more phases, with at least one grounded housing that is filled with protective gas, with open air ducts, which are attached to the housing(s) in a gastight manner and which each have an...

20060138089 - Arrangement comprising a low voltage power switch and a switching gas damper provided with a carrier element and used for the low voltage power switch: A switching gas damper is for low voltage power switches, especially for low voltage power switches which can be inserted into low voltage switching installations. The switching gas damper is arranged above an arc extinguisher of the low voltage power switches and includes at least one inlet for switching gases...

20060131278 - Opening/closing mechanism for vacuum processing apparatus and vacuum processing apparatus using the same: An opening/closing mechanism for a vacuum processing apparatus comprises a link mechanism comprising a supporting member having first and second valve elements for closing first and second opening portions, and a base end side member rotatably attached at a rear edge portion side of the supporting member through a rotation...

20060124599 - Grounding switch having a moveable contact piece: A displaceable contact piece of an earthing switch transverses the wall of a housing of a capsule. Said displaceable contact piece is sealed with respect to the capsule housing wall by means of a sealing element. The displaceable contact piece is connected in an electrically conducting manner to the capsule...

20060124600 - Vacuum interrupter: A vacuum interrupter for reducing contact resistance and thereby reducing electromagnetic repulsive force between electrodes, is obtained. The vacuum interrupter includes a stationary electrode rod fixedly placed on one closed end of a cylindrical evacuated envelope closed at both ends thereof; a movable electrode rod movably placed on the other...

20060124601 - Contact element comprising rounded slot edges: The aim of the invention is to prevent local spikes from being created in a contact element of a contact arrangement used for interrupting a current in a distribution network, said contact element comprising a contact support (8) that encompasses a hollow cylindrical wall section (9) and a bottom wall...

20060124602 - Arc chute assembly: The arc plates of an arc chute assembly for a circuit breaker are supported in spaced, stacked relation by a structural shell molded of a gas evolving resin. Generation of arc gases, that cool the arc thereby increasing the current interruption capability of the breaker, can be further enhanced by...
