Definitions

  • All switching devices that protect people and / or things from dangerous effects of the to protect electrical current such as residual current circuit breakers, Miniature circuit breakers, main circuit breakers, motor circuit breakers, Circuit breakers and the like contain triggers that are fault currents or overloads or Detect short circuits and then switchgear if limit values are exceeded trigger. Thereupon the main current contacts of the switching devices open, so that normally no harmful electricity can flow.
  • a forced device is known Disconnect mains or main power lines, using a working memory that is a force provides along a path and that by means of a ratchet in an inactive Condition is maintained, with a shutter release with little effort triggerable and thus the RAM can be released so that it from the inactive in passes its active state, one driven by the working memory Disconnect device in the triggered state, the forced separation of the network or Main power lines.
  • the invention is based on the object in the event of failure of the Switching devices mentioned above, in particular for residual current circuit breakers, a Device for the forced and very quick disconnection of the associated network or Show main power lines, in order to endanger people and / or things to exclude.
  • the particular advantage of the device according to the invention is that it is direct in circuit breakers of the type mentioned at the beginning or as an additional device with these in series can be arranged.
  • circuit breakers with suitable conventional Current measuring systems in particular measured the fault, overload or short-circuit currents and these measured values are also used by the device.
  • Exceed the measured values a predetermined limit value and the respective circuit breaker does not switch within a certain time, the network or Main power lines separated. So basically the existing regular fails Protection function of the switchgear for different reasons, so the Device easily reliable and within a certain harmless Time the live lines. This forced separation of the lines is normal a unique and irreversible process, so that after that at least the circuit breaker or the switching device must be replaced and the device reactivated.
  • a spring accumulator is provided as the working memory interacts with a lever lock and a fuse wire as a trigger.
  • a compression spring 2 and above a piston 3 with a Tappet 3.1 arranged, which represent the essential parts of the spring accumulator.

  • the mainspring is in the range of The knee levers 4 'which engage the spring eyelets and are arranged in the interior of the spring, as in FIG shows. So that the toggle lever 4 'its almost extended position and thus the spring tension can maintain, it is also locked by a fuse wire 5.
  • This is with One end preferably attached to the toggle joint and the other end to the Shell surface of the housing held and led out.
  • Another tension spring 6, whose direction of action and points of attack roughly correspond to the position of the fuse wire, supports the latter in his task.
  • the tension spring 6 is considerably weaker designed as the tension spring 2 '. Nevertheless, the tension spring 6 relieves the fuse wire 5 considerably, so that it can be made much thinner than in Embodiment according to Fig. 1. Its operation is analogous here also applicable, that is after the destruction of the fuse wire 5 by one Tripping current drives the tension spring 2 'the plunger 3.1 and this ultimately one Separator.

Also stops a fuse wire 5, the bolt 7 in engagement with the plunger recess, while one on Tension spring 7.1 engaging the bolt against the holding force of the fuse wire tried to unlock.
  • This device operates in the manner already described, that is, according to The spring 7.1 pulls through the melting wire 5 due to a tripping current the bolt out of the recess of the plunger 3.1.
  • the inactive position of the Working memory canceled and then under the action of the compression spring 2 the plunger 3.1 upwards and drives a separating device for forced separation of the power lines.
