    摘要: In a method and a configuration for operating a hydraulic drive, a 3/2-port directional seat valve, which is driven by solenoid coils, controls an application of high-pressure fluid through a working piston of a piston/cylinder system. In order to increase the circuit-breaking capacity of the working piston, a hydraulic booster valve which is driven hydraulically by the 3/2-port directional seat valve is used for clearing a direct path from the piston/cylinder system to the low-pressure reservoir during switching-off.

    摘要: An electrical high-tension circuit breaker with main contacts and auxiliary contacts in parallel to the main contacts. Both sets of contacts are actuated by hydraulic drives which are fed from a hydraulic accumulator. The drive of this circuit breaker is of high reliability and small size considering the power to be switched. This is achieved with a main drive which contains a piston-cylinder arrangement which can be pressurized with hydraulic fluid via a main valve and a secondary drive which is actuated via a valve arrangement. The valve arrangement is controllable as a function of the position of the main contacts and/or the auxiliary contacts. With this drive, failure-susceptible elements, such as catches, mechanical dampers and couplings, are avoided. The drive is preferably for high-tension circuit breakers for voltages above 220 kV.

    摘要: An apparatus for operating a combined interrupter disconnect switch is disclosed. The disconnect switch is operated by a slow speed linear motion of a mechanism pullrod. The interrupter, which is a component of the disconnect switch arm, is operated by a high speed linear motion of the same mechanism pullrod. In a preferred embodiment, the apparatus of the present invention comprises: an operating rod; a high speed operating mechanism connected to the operating rod; a sliding gear having an elongated gear face; a motor, rotatably connected to the sliding gear; a coupling gear drive having a longitudinally disposed threaded shaft and an external gear face, connected to the operating rod and meshed with said sliding gear; a threaded rod threaded into the threaded shaft of the coupling gear drive; and a drive rod connected to the threaded rod and to the mechanism pullrod. The high speed operating mechanism and motor respectively provide high speed and slow speed linear motion to the mechanism pullrod. The elongated gear face of the sliding gear permits decoupling of the high speed operating mechanism and slow speed motor, although both are acting on the same mechanism pullrod. In a preferred embodiment, the operating mechanism of the present invention also comprises upper and lower limit switches, controlled by a switch control bracket, for transmitting open and close commands to the high speed operating mechanism and motor.

    摘要: A circuit breaker, in particular a high-voltage circuit breaker employing SF.sub.6 gas, possesses a fixed contact part, and a movable switching piece which is provided with a blast nozzle and can be actuated by a drive. During the process of tripping out, a compression space is rendered smaller to generate a flow of gas towards the blast nozzle and an arc produced during switching out by movement of a movable cylinder over a stationary piston head. In order to reduce the drive power, the compression space is surrounded by a coil for generating a magnetic field. The coil is capable of being switched into the current path in such a manner that, during the process of tripping out, current does not flow through the coil until disconnection has been effected at the main contact point. An auxiliary piston is located in the compression space. The auxiliary piston is capable of being driven by the magnetic field toward the contact point in order to render the compression space smaller.
