Definitions

  • the present invention relates to a vacuum switch for medium voltage according to the preamble of claim 1.
  • a vacuum interrupter is arranged in a cylindrical housing made of insulating material. Above this vacuum interrupter chamber there is a connection element, the clamping part of which is arranged in the interior of the housing and clamps a connecting pin of the vacuum interrupter chamber which projects in the axial direction.
  • This clamping part is screwed to a connection bolt penetrating the housing in the radial direction through a corresponding passage.
  • the clamping part has a pin which engages in a blind hole-like recess in the housing which is diametrically opposite to the passage.
  • the connecting bolt inserted into the passage from the outside is flange-like and is screwed to the housing from the outside.
  • the switching chamber When installing the vacuum switch, the switching chamber, together with the pre-assembled clamping part, is eccentrically inserted into the housing from above and aligned in such a way that when the pins are centered, they come to rest in the recess. Then the connecting bolt is pushed in the radial direction from the outside through the passage and screwed to the clamping part and to the housing.
  • This known vacuum switch is complex in construction and assembly and requires an inner diameter of the housing, which enables the eccentric insertion of the clamping part together with the vacuum interrupter.
  • Fastening the vacuum interrupter chamber in the axial direction on the connecting element requires little space, in particular in the radial direction, and permits a very simple type of fastening, for example by means of a screw.
  • the slim design of the connecting element that can be achieved in this way enables the insertion of a one-piece connecting element through a passage which does not make it necessary to enlarge the housing.
  • connection element is specified in claim 3. This allows the connection element to be attached to the housing in a very simple manner. Furthermore, this gives the possibility of attaching connection elements of different cross-section to the housing without changes, simply by inserting another holding element on the housing.
  • a further preferred embodiment of the vacuum switch according to the invention allows a connection element to be easily attached, which is smaller in height and width than the cross section of the passage.
  • connection elements of different cross-section are securely held in a single recess in the housing.
  • connection element is fastened to the housing at a support point opposite the passage (claim 9).
  • the connecting element is thus fixed to the housing at the support point with respect to its longitudinal direction and is supported in the transverse direction at the passage and also at the support point.
  • connection element can be clamped at the support point on the housing, glued or pinned to it or the like.
  • the housing has at the support point a further passage running in the radial direction, which is penetrated by a pin on the connection element on which an anchoring part sits on the outside of the housing.
  • the pin can have a thread on which a nut is seated in order to fasten the connecting element to the housing.
  • the anchoring part is covered by a cover made of insulating material. This increases the dielectric strength.
  • the vacuum switch for medium voltage shown purely schematically in FIGS. 1 to 3 has a vacuum switching chamber 12 arranged in a cylindrical housing 10 made of insulating plastic. Above the vacuum switching chamber 12, a connection element 14 is led out in the radial direction, parallel to it and below the vacuum switching chamber 12, a connection part 16 is led out of the housing 10 in order to electrically connect the vacuum switching chamber 12 to connecting conductors or busbars, not shown.
  • the essentially cylindrical vacuum interrupter chamber 12 the longitudinal axis of which is designated by 18 and indicated by dash-dotted lines, is of a generally known type and has switching contacts 22, 24 in a switching chamber housing 20 made of insulating material (FIG. 1).
  • the upper fixed switching contact 22 is arranged on the end face of a contact pin 26 which is passed through the switching chamber housing 20 in the axial direction and is firmly connected to the latter.
  • the contact pin 26 bears against a contact surface 28 of the connection element 14 and is fastened thereon by means of a screw 30 running in the axial direction.
  • the vacuum interrupter 12 is therefore carried by the connection element 14.
  • the lower, movable switching contact 24 is arranged on the end face of a contact plunger 32 which extends downward from the switching chamber housing 20 in the axial direction and which, by means of a drive 34 which is only indicated schematically, in the direction of the axis 18 from an on position shown in FIG. 1 to an off position and can be brought back.
  • the contact plunger 32 is electrically connected to the connecting part 16 by means of a roller contact arrangement 36 (FIG. 3).
  • the cylindrical housing 10 which is arranged coaxially to the vacuum interrupter chamber 12, has a passage 38 for the connection element 14 in the radial direction, which is adapted to the cross section of the connection element 14.
  • the connecting element 14 is a profile piece with a square cross section with rounded corners, the longitudinal axis of which is designated by 40.
  • the connecting element 14 is tapered in its section 42 arranged in the housing 10 in the direction of the longitudinal axis 18 of the vacuum switching chamber 12 and rests with its end face 44 on this side against the inner lateral surface 46 of the housing 10.
  • the surface of section 42 that comes to lie at the bottom during assembly forms the contact surface 28 against which the contact pin 26 rests.
  • a further passage 48 is provided in the housing 10 diametrically opposite the passage 38 and is penetrated by a pin 50 provided on the end face on the connecting element 14.
  • the pin 50 has a thread, not shown, into which a nut 52 is screwed in order to fasten the connecting element 14 to the housing 18.

These contact rollers 84 are connected to the corresponding lug 76 and the contact plunger 32 by means of compression springs 86, only one of which is shown in FIG. 3 pressed. When the switching plunger 32 moves, the contact rollers 84 roll on the lugs 76 and on the contact plunger 32, as a result of which the roller cage 78 runs along half the stroke of the contact plunger 32.

  • the connecting part 16 When assembling the vacuum switch, the connecting part 16 is first led with its section 66 ahead through the cover element 88 and the passage 72 from the outside into the housing 10 and fastened to the intermediate floor 62 by means of the screws 68 and nuts 70.
  • the vacuum switching chamber 12 is then lowered from above into the housing 10 together with the roller contact arrangement 36 seated on the contact plunger 32, and the roller contact arrangement 36 is thereby inserted into the passage 74 in the section 66 of the connecting part 16.
  • the connecting element 14 is then pushed with its pin 50 ahead through the cover element 56 and the passage 38 until the end face 44 abuts the inner circumferential surface 46 of the housing 10 and the pin 50 pierces the passage 48.
  • the connecting element 14 is fixed by placing and tightening the nut 52 on the pin 50.
