Definitions

  • the invention relates to an earthing switch with a movable contact piece, which, by means of a sealing element, extends through an electrically conductive encapsulation housing wall, the movable contact piece being electrically conductively connected to the encapsulation housing wall via the sealing element designed as a bellows, and being guided in a slide bearing supported on the encapsulation housing ,
  • the earthing switches have bellows-shaped sealing elements which seal the movable contact piece against an encapsulation housing.
  • An electrically conductive connection between the encapsulation housing and the movable contact piece is established via the bellows.
  • the movable contact pieces are guided to the outside in an electrically conductive manner, so that additional external ground lines can be connected to the movable contact pieces.
  • the absence of voltage must first be ascertained.
  • the external earthing cables are attached to the corresponding fixed points. This striking takes place in such a way that sufficient striking distances between the operator and the contact piece to be grounded are always maintained via insulating rods or similar devices. This installation of external earth lines is time-consuming and requires technically trained personnel due to the safety regulations that must be observed.
  • the object of the present invention is to simplify use of an earthing switch of the type mentioned at the beginning.
  • the object is achieved according to the invention in an earthing switch of the type mentioned at the outset in that the movable contact piece can be driven by means of an electrically insulating handle.
  • the use of the sealing element as an electrical conductor for contacting the movable contact piece eliminates the need for complex electrical connection of the contact piece. Constructions to connect the movable contact piece to a fixed earthing point, for example by means of sliding contacts or flexible contact strips, are therefore no longer necessary. This reduces the number of modules of the earthing switch and thus creates a simplified design. This also reduces the size of the earthing switch.
  • a bellows has the advantage that it allows axial movement through a housing wall. At the same time, the bellows Relatively large conductor cross-section provided for deriving a short-circuit earth current.
  • a plain bearing allows inexpensive guidance of the movable contact piece.
  • the slide bearing is designed in the form of an insulating material bush. This creates a mechanical closure of the interior of the encapsulation housing from the space that serves to receive the contact piece that is guided through the wall. This means that no foreign particles can migrate from one space to the other over this limit.
  • a type of bulkhead can thus be formed by this slide bearing.
  • this bulkhead is not gas-tight, insulating gas located, for example, inside the encapsulation housing can continue to flow through the slide bearing. This ensures dielectric strength.
  • an inexpensive earthing switch can be manufactured since complex electromechanical drive devices are not required.
  • the electrically insulating design of the handle protects an operator from electrical flow which could occur, for example, if the earthing switch is operated incorrectly.
  • the handle can be constructed extremely simply, since a movement of the movable contact piece in the axial direction of the
  • Handle can be transferred directly to the contact piece. Deflecting gears, levers etc. are thus avoided.
  • the insulating handle is slidably mounted in a guide element.
  • the sliding mounting of the handle in a guide element allows the earthing switch on the drive side to be kept free of shafts, axes or other rotating elements.
  • the guide element can be designed such that it surrounds the bellows.
  • the guide element can, for example, be tubular and flanged to the encapsulation housing wall. The guide element can be used at the same time to accommodate a locking device of the earthing switch.
  • Figure shows a section through an earthing switch with a movable contact piece.
  • FIG. 1 a section of an encapsulation housing of a pressurized gas-insulated switchgear is shown.
  • An electrical conductor 1 is mounted insulated in the interior of the encapsulation housing.
  • the encapsulating housing is filled with an electronegative gas under increased pressure for insulation purposes.
  • a movable contact piece 3 of an earthing switch 4 extends through an encapsulation housing wall 2.
  • the encapsulation housing wall 2 is made of an electrically conductive material, for example aluminum, and has an earth potential.
  • the movable contact piece 3 is designed in the form of a bolt and can be displaced along its axis of rotation. In the switched-on position of the earthing switch 4, the movable contact piece 3 is moved into a mating contact 5 located on the electrical conductor 1.
  • the moveable Contact piece 3 is mounted in a slide bearing 6.
  • the slide bearing 6 is designed in the form of an insulating bush and offers mechanical protection against the ingress of foreign particles which may occur in the area of the drive of the earthing switch 4 into the interior of the encapsulation housing.
  • a bellows 7 is arranged coaxially with the movable contact piece 3 for the gas-tight sealing of the movable contact piece 3 with respect to the encapsulation housing wall 2.
  • the bellows 7 is connected at its first end 8 to the encapsulation housing wall 2 in a gastight and electrically conductive manner.
  • an O-ring 9a is inserted at the joint between the encapsulating housing wall 2 and the bellows 7.
  • the bellows 7 is electrically conductively connected to a cylindrical plate 11. This connection can be made separable, whereby a gas-tight connection between the cylindrical plate 11 and the bellows 7 is maintained by an O-ring 9a.
  • a circumferential pressure ring 21 pressed on with a few screws or a plurality of screws 22 arranged on the circumference of the bellows 7 can be used.
  • An insulating handle 12 is arranged on the surface of the cylindrical plate 11 facing away from the movable contact piece 3.
  • the movable contact piece 3 can be transferred from its switch-off position to its switch-on position and vice versa by means of the insulating handle 12.
  • the earthing switch 4 is shown in its off position.
  • the cylindrical plate 11 is slidably mounted within a hollow cylinder 13, which serves as a guide element.
  • the cylindrical plate 11 is slidably supported in the hollow cylinder 13 by means of a circumferential plastic ring 20.
  • the hollow cylinder 13 protects the bellows 7 from external mechanical influences.
  • the cylindrical plate 11 has an opening 14 lying perpendicular to the direction of movement of the movable contact piece 3.
  • the opening 14 lies in alignment with a first pair of openings 15a, b in the switched-off position of the earthing switch 4, so that a locking pin 16 can be pushed into the opening 14 through the first pair of openings 15a, b.
  • the locking pin 16 can be locked by means of a padlock 18, so that movement of the movable contact piece 3 is only possible after unlocking the padlock 18 and removing the locking pin 16.
  • a second pair of openings 19a, b are introduced into the hollow cylinder 13, to which the opening 14 is in alignment when the earthing switch 4 is switched on, so that the movable block can also be blocked by means of the locking bolt 16 when the earthing switch 4 is switched on Contact piece 3 is enabled.
