Definitions

  • the invention relates to a high-voltage circuit breaker with a first and a second contact piece, which delimit a separation distance in the switched-off state, a compression piston surrounding the first contact piece, a drivable compression cylinder surrounding the second contact piece in the switched-on state, and with a second contact piece in the switch-off state and surrounding and axially movable first field electrode.
  • Such a high-voltage circuit breaker is known, for example, from DE-OS 42 17 232.
  • a first field electrode is formed by the bottom of the movable compression cylinder.
  • the compression cylinder bridges the separation path, so that the bottom of the compression cylinder, which is designed as a field electrode, coaxially surrounds one of the contact pieces in this position, while the stationary compression piston surrounds the other contact piece.
  • the invention is therefore based on the object of creating a high-voltage circuit breaker of the type mentioned at the outset, in which field electrodes are provided on the one hand for uniformizing the electric field around the region of the isolating section and, on the other hand, the isolating section in the switched-off state has the highest possible dielectric Has strength.
  • the object is achieved in that the first field electrode is separated from the compression cylinder and is designed to be axially movable relative to the latter and that the compression cylinder is at a distance from the second contact piece in the switched-off state.
  • the first field electrode in the region of the second contact piece can be brought into the most favorable dielectric position.
  • the first field electrode can then be displaced axially in order to make room for the compression cylinder.
  • the invention can advantageously be designed in such a way that the first field electrode is spring-loaded axially in the direction of the compression cylinder and that a stop is provided which limits the movement of the first field electrode towards the separating path.
  • the spring load is the drive for the field electrode and thus the field electrode runs during the switch-off process when the compression cylinder is retracted, until it hits the stop that limits the movement of the field electrode and determines the end position of the field electrode .
  • the compression cylinder is pushed forward and pushes the first field electrode back against the spring force until the compression cylinder has reached its end position.
  • a further advantageous embodiment of the invention provides that the end faces of the first field electrode and the compression cylinder at least partially overlap one another in their axial projection.
  • the first field electrode and the compression cylinder can, for example, have the same or similar outer diameter, so that the entire interrupter unit can be accommodated in a space-saving manner with respect to its diameter.
  • the inner diameter of the field electrode can, for example, be chosen so that it is slightly larger than the outer diameter of the second contact piece, so that the second contact piece simultaneously represents a guide for the axial movement of the first field electrode.
  • Another advantageous embodiment of the invention results from the fact that the compression piston is designed as a second field electrode.
  • This compression piston surrounds the first contact piece, so that each of the contact pieces is then surrounded by a field electrode in the switched-off state. This results in a symmetrical design of the electrical field with respect to the isolating section, which increases the dielectric strength of the isolating section.
  • the compression piston can advantageously be drivable in the direction of the second contact piece.
  • the compression piston then moves towards the compression cylinder during the switching-off process, as a result of which a stronger one Compression of the extinguishing gas is reached. Finally, the compression piston is stopped in the dielectrically most favorable position.
  • the first field electrode is connected to a telescopic rod which serves as a spring guide for a compression spring which brings about the axial movement of the first field electrode.
  • FIG. 2 shows the circuit breaker from FIG. 1 during the opening movement
  • FIG 3 shows the circuit breaker from FIGS. 1 and 2 in the switched-off state.
  • the first contact piece 1, the second contact piece 2 as well as a compression piston 3 and a compression cylinder 4 which can be driven by a drive device (not shown) are shown in the figures of the circuit breaker according to the invention. All parts of the circuit breaker shown are rotationally symmetrical with respect to the central axis of the contact pieces 1, 2. However, in order to simplify the illustration, only the upper half of the arrangement was partially drawn.
  • the compression cylinder 4 bridges the separation distance between the contact pieces 1 and 2.
  • a bridging contact piece 5 is firmly connected, which consists of individual contact lamellae, which are arranged on the circumference of a cylinder.
  • the contact lamellae are supported radially outwards via springs 6 against a holding tube 7.
  • Both the bridging contact piece 5 and the holding tube 7, the compression cylinder 4 and the turbulence grille 8 are moved to the right in the course of the disconnection movement in FIG. 1.
  • the bridging contact piece 5 runs from the second contact piece 2 and interrupts the galvanic contact between the first contact piece 1 and the second contact piece 2.
  • a telescopic rod 12 is extended, which is connected to the first field electrode 9 and serves as a spring guide for the spring 10.
  • FIG. 2 shows the compression cylinder 4 in an intermediate position in which the bridging contact piece 5 has already expired from the second contact 2.
  • Bridging contact piece 5, holding tube 7 and springs 6 are not shown in FIGS. 2 and 3 for the sake of clarity.
  • FIG. 3 shows the switch-off state in which the compression cylinder 4 has been largely pulled out of the separation distance between the first contact piece 1 and the second contact piece 2.
  • the volume between the compression piston 3 and the compression cylinder 4 has decreased during the switch-off process to such an extent that compressed extinguishing gas from this volume through the turbulence grating 8 in the space between the first contact piece 1 and the second contact piece 2 has flowed in order to extinguish an arc standing there.
  • the compression cylinder 4 consists of an insulating material, so that it affects the dielectric strength of the separation path only slightly.
  • the first field electrode 9 follows the compression cylinder 4 during the switch-off movement until the stop 13 limits the movement of the field electrode 9 and determines its position in the switch-off state. In this position, the first field electrode 9 uniformizes the electrical field in the region of the second contact piece 2.
  • the arrangement consisting of the contact pieces 1, 2 and the two field electrodes 3, 9 leads overall to a uniformization of the electrical field between the contact pieces and thus to an increase in the dielectric strength of the isolating path.
  • the stop 13 can, for example, also be integrated in the telescopic rod 12.
