Definitions

  • the invention relates to an electrical switchgear with a series circuit consisting of a first disconnector / earthing switch, a circuit breaker and a second disconnector / earthing switch.
  • Such a switchgear is well known. It is also known that each of the three switches, a drive is assigned, with which the respective switch can be switched to its switching positions.
  • the two isolator / earthing switches may only be earthed one after the other. This can be achieved, for example, by electronically monitoring the switch positions of the two isolator / earthing switches and, depending on the determined switching positions, influencing the drive for the respective isolator / earthing switch. In this way, thus by means of the monitoring of the switching positions and the corresponding control of the drives of the two isolator / earthing switch a simultaneous changeover of both disconnector / earthing switch can be avoided in the grounded position.
  • the object of the invention is to improve the known switchgear.
  • a switching drive having a component provided with a first cam track associated with the first disconnector / earthing switch and provided with a second cam track associated with the second disconnector / earthing switch, wherein the component is drivable by a single drive.
  • the switching positions of the two isolator / earthing switch can be specified via the two curved paths. With the help of the two curved paths, any change or sequence of switching positions of the two isolator / earthing switches can thus be set in advance in a desired manner. Since the two cam tracks are arranged on or on the same component, only the set switching positions of the two isolator / earthing switch can occur. However, other switching positions or changes in the switching positions can not occur.
  • the two isolator / earthing switch can be locked by the invention in terms of their switching positions in a desired manner to each other.
