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 by closing a current path, namely the auxiliary circuit, via a test resistor from one phase to another, bypassing the summation current transformer, when the test button is pressed. This is an imitated fault current that triggers the release of the residual current circuit breaker and thus unlatches 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.
  • EP 0 231 732 describes a residual current and line circuit breaker with a switch for a center conductor, in which the movable switching bridge (switching element) of the line circuit breaker arranged in one housing part with the movable contact arm of the switch for the center conductor accommodated in another housing part via a is coupled to a partition wall guided slide.
  • the switch has a contact position indicator and a test device, both of which can be actuated by this slide. The slide moves the contact position display device so that the respective switching position of the FI / LS switch is indicated by a window in the housing.
  • the slide is coupled to the one leg of a test contact spring belonging to it, which is assigned to a test contact, such that the leg is lifted from the test contact in the "off" switch position and the test circuit is interrupted and also when one is actuated on the second leg acting test button is not closable, and arranged in the "on" switch position adjacent to the test contact and the test circuit can be closed by pressing the test button.
  • 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 indicator 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 connected to the movable contact 2 in an electrically conductive manner and fastened in the control 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 .
