Definitions
- the invention relates to a high-voltage switch with a hydraulic spring-loaded drive, with a spring arrangement serving as an energy store, with the hydraulic Pressure is generated with which the drive piston of the hydraulic spring-loaded actuator can be actuated and controlled, and with one with the drive piston connected piston rod, which with the at least one switching contact piece or one pole of the high-voltage switch is connected.
- Such a high-voltage switch with a corresponding hydraulic drive is known per se (see EP 0 158 054).
- the switch position indicator Switching elements are provided with which the piston rod is coupled such that the Start and end of piston rod movement by operating the switches can be determined.
- further switching elements are assigned to the drive, which detect the movement of the spring accumulator.
- the spring accumulator assigned a curve piece that is movable with the spring accumulator, the is tapped from the switching elements.
- the object of the invention is to provide a high-voltage switch of the type mentioned To create a way in which the wiring effort is significantly reduced.
- This object is achieved in that the linear movement of the movable end of the spring arrangement by means of an inductive encoder and the End positions of the drive piston can be detected by means of a proximity switch and that the signals of the encoder and that of the proximity switch of an evaluation unit are feedable.
- An inductive or optical rotary encoder can be provided as the rotary encoder; prefers becomes an inductive.
- Such an inductive rotary encoder is known per se. He is in able to detect rotational positions of its shaft and convert them into signals that can then be further processed in an evaluation device. You can also the proximity switches are inductive or optical proximity switches. Also be here inductive preferred.
- An advantageous embodiment of the invention can go that with the movable A movable rack section is coupled to the end of the spring arrangement, with which a pinion meshes, which is connected to the axis of the encoder.
- the corresponding proximity switch is actuated, so that the beginning and end of the piston rod movement and thus the switching position of the high-voltage switch can be detected directly.
- a high-voltage circuit breaker 10 of a high-voltage system which in FIG. 1 is only shown symbolically, and can be single or multi-pole, is via a Line of action 11 by means of a joint 12 with the piston rod 13 of a drive piston 14 coupled, which is guided back and forth in a cylinder arrangement 15.
- a slider 16 On the piston rod 13 in the region of the joint 12, a slider 16 is attached, which also on a guide rod running parallel to the piston rod 13 17 is guided linearly.
- an extension 18 is arranged, which in the 1 opposite a first proximity switch 19, the Output signals are fed via a conductor 20 to an evaluation unit 21. In the shown position, the switch 10 is in the on position.
- a holder 25 is fastened on which a support wall 26 is attached to which a rotary encoder 27 is attached, the shaft 28 is parallel runs to the piston rod 23.
- a pinion 29 is attached to the free end of the shaft 28.
- a sliding shaft 30 is fixed between the legs 25a and 25b of the holder 25, which is shown in dashed lines in Fig. 1.
- a sliding plate 31 slides on this sliding shaft 30 transverse to the movement of the piston rod 13, on its side facing the pinion 29 a meshing with the pinion 29, extending transversely to the piston rod movement Rack section 32 is attached.
- a transmission rod 36 is connected, which with a joint 37 is connected to the slide plate 31 so that when the pressure plate moves 35 in the double arrow direction P, the sliding plate 31 also moves on the sliding rod 30.
- the pinion 29 is driven so that the pinion 29 drives the shaft 28.
- the resulting signals from the encoder 27 are fed to the evaluation unit 21 via a third line 38.
- the spring storage arrangement 33 can also perform a movement in the direction the piston rod runs, likewise the encoder shaft 28 can be oriented differently, e.g. B. perpendicular to the piston rod movement, and the rack section also, which depends, among other things, on the available space.
