摘要： A thermally actuated device, such as an electrical circuit breaker (10) is provided with an ambient temperature compensation thermostat metal member (38) selected so that it bends when subjected to changes in temperature and compensates for ambient temperature effects on a thermostat metal trip arm for a selected current rating. Movement of such thermostat metal member is directly proportional to the flexivity of the material and to the square of the length of the member and indirectly proportional to the thickness of the member. Since packaging constraints make changes in length impractical, compensation members used to provide temperature compensation for different current ratings of the device typically have been made by using members of different thickness. In accordance with the invention, ambient temperature compensation members for a family of devices having a plurality of different current ratings is provided by changing the effective length of respective blank thermal compensation members by stamping selected deformations (48c, 50c) appropriate for each current rating in respective blank compensation members.

摘要： A high-voltage switchgear having a fixed and a moving contact member includes a hydraulic drive for operation of the moving contact member having a piston and cylinder configuration with a piston coupled to the moving contact member. A fluid reservoir configuration supplies fluid under pressure to the piston for driving the piston. A compressor unit at ground potential charges the fluid reservoir configuration. Electrically-insulating, pressure-resistant lines respectively connect the compressor unit with the piston and cylinder configuration and with the fluid reservoir configuration. The piston and cylinder configuration and the fluid reservoir configuration are disposed spatially close to and at the same electrical potential as the moving contact member.

摘要： A hydraulic or pneumatic drive for actuation of a movable switch contact of a medium and/or high-voltage power switch, especially an SF6-gas-insulated high-voltage power switch, includes a drive piston coupled to the movable switch contact. Fluid is delivered under pressure to the drive piston from a fluid reservoir configuration in order to perform one switching cycle having a given number of required switching operations. The fluid reservoir configuration has the given number of mutually separate independently acting storage chambers each having an energy content sufficient for a required switching operation.

摘要： Two circuit breakers or circuit breaker modules are actuated by hydraulic jacks fed by supply and drain valves operated by a single closing-operation control unit. A differential pressure detector is subjected to the pressure of the two jacks. In the event of a relative variation in the jack-operating times, the free piston of the detector actuates a switching device which connects the supply and drain valves to the drain tank, thus preventing the complete performance of any non-simultaneous operation of the circuit breakers.

摘要： A shorting element for closing a superconducting current path using contacts of a stabilized superconductor material with the contacts being brought together through the use of a mechanical actuating device, in which the contact surfaces of the contact elements are brought into contact using a pneumatic and/or hydraulic means operated by a pressure medium fed into the interior of at least one spring bellows. The shorting element, which is particularly useful in shorting superconducting magnets, is of a simple design, operationally reliable, and results in small coolant losses from the addition of heat through the shorting element.
