Definitions

  • the invention relates to a test device for residual current circuit breakers according to the preamble of claim 1.
  • Such a test device which has become known from DE-PS 26 18 295, is required in the case of residual current circuit breakers in order to test the functional reliability and readiness of the residual current release. This is achieved in that a current path, namely the auxiliary circuit, is closed by pressing the test button via a test resistor from one phase to the other, bypassing the summation current transformer. It is an imitated fault current that triggers the release of the residual current circuit breaker and thus releases the mechanism of the residual current circuit breaker.
  • a residual current circuit breaker which has a test button for closing a test circuit, with the aid of which a mimicked fault current triggering the trigger of the residual current circuit breaker can be switched on, is known from DE-PS 27 33 837.
  • the counter contact piece of the switch for the test circuit is formed by a part of the switch lock, which pivots out of the effective range of a leg of the leg spring when the switch lock is triggered.
  • the invention is based on the object of a test device to develop for residual current circuit breakers of the type described above, which can be combined with a contact position indicator in a small space, and that parts of both the test device and the contact position indicator are designed for both functions.
  • a switching shaft 1 with a movable contact 2 and a fixed contact 3 are used in the lower part of the switch housing 11 .
  • a spiral spring 4 is connected to the control shaft 1 , which protrudes into the upper part of the switch housing 11 .
  • the end of the spiral spring 4 corresponds to a lever 61 of the contact position indicator 6 , which is provided with an axis of rotation 10 .
  • the freedom of movement of the spiral spring 4 is limited by two stops 63 and 64 of the lever 61 .
  • the contact position display device 6 is equipped with a further lever 62 which is divided into two identical sections which are marked with different identification colors. One of the sections of the lever 62 can be seen through an opening 12 of the switch housing 11 .
  • the position of the contact 2 is transmitted via the control shaft 1 , the spiral spring 4 to the contact position display device 6 and made visible to the outside via the lever 62 through the opening 12 of the switch housing 11 .
  • the lever 62 is limited in its rotational movement by stops 8 and 9 .
  • the test device consists of a test button 7 with an extension pin 71 , the length of which is dimensioned such that it contacts a contact spring 5 .
  • the contact spring 5 is designed as a torsion spring with an axis 52 and has a kink 51 in the central region.
  • test device works as follows: When test button 7 is pressed, the test device closes an auxiliary circuit, with which the function of the residual current circuit breaker can be tested. The auxiliary circuit must not be able to be closed when it is switched off.
  • the spiral spring 4 which is electrically conductively connected to the movable contact 2 and fastened in the switching shaft 1 , rotates the contact position indicator 6 about the axis 10 in the counterclockwise direction to the stop 9 .
  • the movable contact 2 moves through the switching shaft 1 in the direction of the fixed contact 3 .
  • the spiral spring 4 rotates the contact position indicator 6 clockwise against the stop 8 .
  • the opening 12 of the switch housing 11 one can see the assigned identification color of the contact position indicator 6 .
  • the auxiliary circuit is closed by pressing the test button 7 .
  • the contact spring 5 touches the spiral spring 4 .
