Definitions

  • Switching device for connecting and disconnecting or earthing sections of the track in overhead contact line systems
  • the invention relates to a switching device for connecting and disconnecting or earthing sections of the line in overhead contact line systems, comprising at least one first rod insulator fixedly mounted on a base and a second rod insulator which is pivotably held on the base, and a contact insulator and contact springs arranged at the free end of the rod insulators formed switch contact set.
  • Switching devices of the aforementioned type are referred to in technical jargon as isolating switches if they are used for dividing sections of track, for connecting parallel tracks or for dividing infeeds. They are referred to as earthing brackets if they are to be used to earth a section of the route that has already been switched off. Disconnectors are also available in combination with an earth contact, i.e. After separating the section of the route, it is also connected to earth.
  • Such switching devices are usually mounted on crossbars on overhead line masts.
  • Known switching devices of this type as described for example in the Siemens catalog FM 1995, section 13/6, comprise two isolators, one of which is rigid and the other is pivotably arranged on an axis for switching on and off on a base.
  • the rod insulators are made of ceramic and firmly cemented to the base.
  • the invention specified in claim 1 is therefore based on the object of specifying a switching device of the type mentioned, which in particular is of simpler construction, is less prone to failure and which is easier to assemble, in particular for maintenance work.
  • the switching device presented according to the invention only needs to fall back on two different components, on the one hand, preferably L-shaped contact blades and, on the other hand, on contact springs on both sides of the contact blades.
  • these two components which are preferably of the same design in all variants of the switching device, both isolating switches and earthing switches and a combination of both switches can be put together.
  • switches with different functions can be produced inexpensively.
  • the contact springs are advantageously held in an adjustable manner on the contact blades. This allows the contact springs to be adjusted precisely to the contact blades; Manufacturing tolerances can be largely compensated for and the contact resistance reduced to a minimum.
  • the contact springs are advantageously provided with adjusting means with which the spring force of the contact springs can be adjusted.
  • a particularly simple construction, in particular with a view to replacing a contact set or a rod insulator, can be achieved if, according to a further advantageous embodiment of the invention, the switch contact set is directly attached to the rod insulators by the one leg of the L-shaped contact blades are detachably attached directly to connecting parts of the rod insulators.
  • the pivoted rod insulators can advantageously have an actuating element on one leg of the contact blade, which actuates a signal switch (position switch) located on the fixed rod insulator in the case of an earthing switch. This means that a signal for the existing grounding can be given when the contact set is closed.
  • the rod insulators are detachably mounted on the base; for this purpose, the rod insulators are sleeve-shaped at least at the base-side end and are placed on appropriately designed holders which can be fastened in the base.
  • the brackets are expediently held adjustable with the aid of suitable adjusting screws both with respect to the base and with respect to the rod insulators.

  • the rod insulator 2 is fixedly mounted on the base 1, the rod insulator 3 is pivotally supported by means of a joint 5.
  • a drive (not shown in the drawing) engages, which causes the pivoting movement (see arrows) in the event of a shutdown of the section of the route.
  • Loschhorner are designated, which protect the line contacts of the switch contacts explained later in more detail when switching on and off.
  • FIG. 2 shows the arrangement according to FIG. 1 with an additional earth contact.
  • a holder 8 which is connected to the earth line, is provided on the base 1 and accommodates a plurality of contact springs 9, which correspond to a contact knife 10.

  • FIG. 3 shows a version which is constructed in a similar manner using the same components, but is here designed as a pure earthing switch.
  • the earthing switch is drawn here in the open state (normal case); in this position the switch contact pairs 4.1 and 4.2 of the switch contact set 4 are separated from each other.
  • Protective hoods 13, 14 are arranged above the two switch contact pairs 4.1 and 4.2, which protect the switch contacts against mechanical damage and weather influences. The same applies to the previously described embodiments.
  • the switch contact set 4 comprises the two switch contact pairs 4.1 and 4.2, one of which is assigned to the fixed rod insulator and the other to the rod insulator which is held pivotably.
  • Each switch contact pair is constructed identically and essentially consists of two parts, an L-shaped bent contact knife 15 and a contact spring 16 mounted thereon.
  • the contact knives and the correspondingly arranged contact springs are rotated in pairs and rotationally symmetrically arranged.
  • the contact springs 16 are adjustably attached to one, longer leg 15a so that they can be aligned with the contact blades corresponding to them on the other pair of contacts.
  • the screw connection indicated by 17 is expediently guided in an appropriately designed elongated hole.
  • This adjustment can be used to compensate for manufacturing tolerances which occur, for example, when the contact blades 15 are bent. In this way, contact resistances occurring during switching can be reduced to a minimum.
  • the spring force can also be adjusted by spring-loaded adjusting means 18 and thus adapted to the circumstances.

  • the end of the rod insulator can also be used rod-shaped and adjustable in a correspondingly provided sleeve of the base.
