Definitions

  • the invention relates to an arrangement with a movable guided in a slide assembly blocking element and a rigid angle connected to a shaft pivot lever, which is part of a kinematic chain for moving a movable contact piece of an electrical switching device, wherein by means of the blocking element, the kinematic chain is blocked and the Shaft through a fluid-tight encapsulating housing of the electrical switching device, the pivot lever disposed outside of the encapsulating and the blocking element is movable in a pivoting range of the pivot lever.
  • Such an arrangement is for example from the utility model DE 1 762 100 known.
  • a hand-operated pivot lever the necessary drive energy for moving a movable contact piece is fed into a kinematic chain.
  • the hand-operated pivot lever is connected to a shaft, wherein the pivot lever is configured such that a movable blocking element can block the pivot lever.
  • Further arranged between the hand-operated pivot lever and the movable contact piece transmission elements of the kinematic chain are prevented due to the blocking of the pivot lever to a movement. Because of corresponding tolerances at bearing points, connection points etc. at the various transmission elements of the kinematic chain, individual transmission elements of the kinematic chain can perform limited movements despite blocking of the pivoting lever.
  • EP 0 075 922 A1 is a switch for a gas-insulated switchgear known.
  • the switch has a pivot lever which can be blocked by means of a blocking element.
  • the blocking element is mounted in a sliding arrangement.
  • the mechanism can deform and smooth sliding in the slide assembly is no longer guaranteed.
  • a blocking of the pivot lever is no longer guaranteed safe.
  • blocking of movement of a movable contact piece should be done reliably for safety reasons.
  • fluid-tight encapsulation housings With the use of fluid-tight encapsulation housings, it is possible to protect assemblies located inside the encapsulating housing from external influences. Such Assemblies are, for example, contact pieces of the electrical switching device or even sections of the kinematic chain. Thus, it is advantageous, in particular to arrange the movable contact piece inside a fluid-tight encapsulating housing in order to protect it from external influences.
  • the encapsulating housing can be protected from external forces by its mechanical configuration, and on the other hand, the encapsulating housing can be provided to hold a special extinguishing and / or insulating medium inside. For example, it is possible to fill the encapsulating housing with a gas or a liquid. For this purpose, in particular insulating gases such as sulfur hexafluoride, nitrogen or liquids such as insulating oils are suitable.
  • a fluid-tight leading out a rotatable shaft from the encapsulating allows to transmit necessary movements for operation of the switching device in the encapsulating inside.
  • a rotatable shaft can be sealed with simple sealing elements on the encapsulating housing, so that leakage of fluids out of the encapsulating housing or ingress of foreign substances into the encapsulating housing is avoided.
  • the arrangement of the pivot lever outside of the encapsulating it is possible to place other necessary elements, such as auxiliary switches, drive means, etc. also outside of the encapsulating. This allows the volume of the encapsulating be limited and thus the size of the switching device can be reduced.
  • insulating gases which are held with a relation to the environment increased pressure in the interior of the encapsulating, so compact switching devices can be formed.
  • the interface between a region protected by the encapsulating housing and the surroundings is located.
  • the blocking element can be caused in spatial proximity to the movable contact piece a blocking effect.
  • proximity to the movable movable contact piece is located away from electrically active zones, which are preferably located in the interior of the encapsulating.
  • the pivot lever is necessary to convert a linear or approximately linear movement into a rotational movement and to transmit this rotational movement by means of the shaft into the interior of the encapsulating housing.
  • the pivot lever required for a movement of the contact piece can also be used to cause a blocking effect on the movable contact piece can.
  • an end position of the movable contact piece can be secured.
  • Control circuits can be designed, for example, electrically, hydraulically, pneumatically, etc.
  • a lock can be done here, for example, by interrupting the control circuits.
  • the pivoting lever can be formed variedartigst, regardless of the form, however, a point of application for a thrust movement is provided, wherein over the radial distance of the attachment point of the lever to the axis of rotation of the shaft, a force and / or directional deformation of the movement.
  • the pivot lever Since the pivot lever is moved at different speeds depending on the switching device during switching operations, it must be made more or less stable. If the switching device is a circuit breaker, for example, which must realize an activation or deactivation within fractions of a second, a correspondingly massive cuboid design of the lever is advantageous.
  • a further advantageous embodiment may provide that the encapsulating is held in a profiled beam, wherein the blocking element is arranged in a profile niche of the beam.
  • a profile niche is an area protected by the structure of the beam.
  • the niche may be within the outer contour of the beam.

It is also advantageous if the central region of the U-profile protects the profile niche from the weather, as it were a canopy.
  • the central region of the U-profile is suitable for receiving the encapsulating housing.
  • at least one corresponding cutout is provided in the central region of the profile, wherein, for example, a flange provided on the encapsulation housing can be fastened in the edge region of the cutout.
  • the encapsulating housing projects, for example, through the cutout at least partially into the profiled niche of the U-shaped beam.
  • the cutout in the beam corresponds to the shape of the encapsulating housing, so that a flush closing of the recess takes place after the installation of the encapsulating housing on the beam.
  • a further advantageous embodiment may provide that the blocking element is displaceable along a sliding axis, which is aligned approximately parallel to a rotational axis of the shaft.

  • the blocking element has a stop surface, against which a counteracting contact surface of the pivot lever is movable for blocking.
  • the pivot lever has a contact surface which is the same as the stop surface. In this case, a pressing force is distributed to an increased surface area, so that generation of impact marks in the surfaces is reduced. It is particularly advantageous if stop surface and contact surface are designed as flat surfaces which are aligned almost parallel to each other shortly before their touch. Thereby, it is possible to form the blocking member with easy-to-fabricate shapes with a high force absorbing capacity. Next can be provided for the lever an approximately cuboid shape, so that existing constructions continue to be used for pivoting lever or remain ready for use after only slight modifications.
  • a further shaping of the contact and stop surfaces is possible, for example, cylindrical surface structured surfaces, spherical surfaces or Any other structured surfaces are used.
  • Such structures have the advantage that in the blocking state of the blocking element due to an interlocking of corresponding structures, an undesired movement of the blocking element is prevented from a blocking position to a non-blocking position.
