    摘要: The invention relates to a fuel cell system with high-temperature fuel cells, in which some of the heat of the gases flowing out of the anode and cathode is used to that end. The gases that the flow into the anode and cathode are brought to a temperature that is required for operation of the fuel cells and is still tolerable for the cells, having an anode and/or cathode loop. It is provided that for the anode and/or cathode loop, at least that time-referred quantity of reaction gases that is required for attaining the electrical output of the fuel cells is furnished. From the gas flowing out of the anode and/or cathode, an equivalent quantity of gas is removed from the gas loop, and the gas quantity introduced into the loop is dimensioned such that by mixing this gas quantity with the gas returned to the loop from the anode and/or cathode, the temperature of the gas flowing into the anode and/or cathode attains a predetermined operating temperature that is optimal for the service life of the cells and for efficiency.

    摘要: A high voltage disconnect switch, including a countercontact piece having switch countercontacts and being arranged for connection to a source of high voltage. Resilient pre-contact pieces are insulatingly connected to the countercontact piece and include switch contacts disposed for contacting the switch countercontacts. Movable primary contact pieces are arranged to be movable from a first position of separation from the pre-contact pieces and the countercontact piece to a second position in which the primary contact pieces are in contact with the pre-contact pieces but not with the countercontact piece and to a third position in which the primary contact pieces are in contact with both the pre-contact pieces and the countercontact piece. The pieces are configured and arranged relative to one another so that during the closing of the switch the countercontacts contact the contacts after the primary contact pieces are moved to the second position and before they are moved to the third position, and during the opening of the switch the countercontacts separate from the contacts after the primary contact pieces are moved to the second position and before they are moved to the first position.

    摘要: A puffer-type gas blast circuit interrupter composed of two separable contacts defining a power current path and between which an arc is created upon separation movement, in which the movable parts of the gas compressor and/or the region of contact between the contacts of an associated nominal current path are shielded from the region in which the arc is created by a shielding arrangement composed of a stationary cylinder surrounding the nozzle associated with the gas compressor and a shield member carried by the nozzle. Additionally, to reduce the movable mass of the interrupter, at least one of the current paths is constituted by two stationary contact pieces and a movable contact member carried by, and projecting from, the cylinder of the gas compressor. Further, the mass of the moving parts of the system is reduced by providing the shield member carried by the nozzle with a cylindrical projection coaxial with, and slidable relative to, the stationary cylindrical member. Preferably, the interface between the shield member and the cylindrical member is hermetically sealed.

    摘要: A method and apparatus for reducing the mechanical stresses on the shaft of a turboset and on the shaft of the generator coupled thereto upon the occurrence of a three-pole mains short circuit near the generator and upon the subsequent elimination of the three-pole short circuit. A generator switch is connected between the output of the generator and the mains, and a resistor, whose size is adapted to the size of the load on the generator, is connected in parallel with the generator switch. The generator switch is opened upon the occurrence of a short circuit to switch the resistor into the load circuit of the generator and the resistor is again bridged when the short circuit is switched off of the mains.

    摘要: A contact element for a power switch which, in order to open or close the switch, cooperates with an opposite element, with a transitory rotating electric arc forming between the contact element and the opposite element when the switch is operated. The contact element has an electrode part which includes a portion made of an electrically conductive material. This portion defines a contact surface, with the electrode part having a defined width and being curved in the direction of the width to have the form of an open loop having a connecting end and a free end. A current may be introduced approximately tangentially to the open loop at its connecting end, and the free end is spaced from the connecting end in the direction toward the interior of the loop by a distance which is less than the defined width.

    摘要: A gas current blow-out switch has an electrically conducting compression cylinder, a stationary hollow power contact pin supported in the cylinder and a piston surrounding the pin and slidably received in the cylinder for compressing an arc-extinguishing gas therein. A nozzle is affixed to the cylinder for bounding one end thereof. A movable hollow power contact pin is supported coaxially with the stationary contact pin to assume open and closed positions. The switch has an electrically conducting stationary tube axially aligned with and spaced from the compression cylinder; a contact bridge slidably supported by and being in continuous electric contact with the stationary tube and the movable contact pin. The contact bridge has a closed position in which it electrically contacts the compression cylinder and an open position in which it is separated therefrom. An insulator cylinder which surrounds the compression cylinder and is slidable thereon, is coupled to the contact bridge for shifting the latter into its open position upon motion of the insulator cylinder in one direction. A carriage is shiftably arranged on a support and an externally actuated drive member is secured to the carriage and is displaceable between two limits with respect to the carriage. The drive member displaces the carriage after the drive member reaches either one of the limits. The drive member is arranged to displace the piston and the carriage is arranged to displace the insulator tube.
