Definitions

  • the invention relates to a locking device for actuating openings of switch drives in gas-insulated switchgear assemblies.
  • a locking device according to the preamble of claim 1 is already known (advertising letter from distrel PY, year 3.79). However, this locking device has considerable safety deficiencies, since this locking can be released at every switching operation and at any time.
  • Another locking device (advertising lettering from PFI-STERER, year 84) is also known. With this locking device, the front door and thus the access to the fuse carriers can only be opened if the earthing switch of the transformer field has been switched on. However, since any further locking of the earthing switch is missing, there is also the risk that, as soon as the front door is opened, improper handling of the earthing switch will result in a great safety risk for the operating personnel.
  • the invention has for its object to develop a further training of the switching safety system for gas-insulated switchgear of the type described with the aim that as long as the cable connection space is not completely closed again and locked from the outside with a lock or sash, the actuating openings for ring cables , Transformer or earth electrode can also be locked securely.
  • this locking device closes a large security gap and ensures that an improper and thus dangerous switching operation cannot take place and that it basically forces the operator to close or lock the cable connection space before further switching operations.
  • the invention also allows the actuation openings for a ring cable field to be optionally closed, and the actuation openings of the earthing switch to be closed in a transformer field, which is necessary for maintenance work on transformer or transformer leads and fuses. For safety reasons, the earth electrode must never be switched off, it may only be switched off again after maintenance and locking of the door or the lock or sash lock in the safety cable connection compartment.
  • FIG. 1 shows a locking device with a cross slide.
  • FIG. 2 shows a locking device with a vertical slide.
  • the locking device consists of a crank linkage 4 , which is mounted in the holder 5 .
  • the other side of the crank linkage 4 is connected via a fastening bushing 6 to a linkage lever 7a perpendicular to the axis of the crank linkage 4 and a return spring 8 under tension.
  • the articulation lever 7a is connected to the slide 9a and the guide slots 16 provided therein, which serve to receive the guide elements 10a , via an elongated hole 15 and a pivot pin 18 , so that the slide 9a is movable in the horizontal direction and the actuating opening 12 through a slot 11 (not shown) in the actuating shaft 2 and at the same time closes the door 1a of the cable connection space.
  • the crank linkage 4 and the cam extension 13b are provided with a safety cover 20 against mechanical manual action when the locking device is open.
  • the locking device consists of a crank linkage 4 , which is mounted in a holder 5 .
  • the other side of the crank linkage 4 is connected via a fastening bush 6 to a link lever 7b and a return spring 8 under tension.
  • the link lever 7b is connected to the slide 9b , which is seated in a guide element designed as a slide box 10b , via an elongated hole 15 and a hinge pin 18 , which is introduced in the extension of the slide 9b , so that the slide 9b is movable in the vertical direction and Actuating opening 19 of the actuating shaft 2 and the extension member 13a simultaneously closes a flap 1b of the cable connection space.
  • the crank linkage 4 and the bolt 13a are provided with a safety cover 20 against mechanical manual action when the closure device is open.
