Definitions

  • the present invention relates to a residual current device with a first flow path for guiding a Nutzstrom, a second flow path for returning the Nutzstroms and a tester having an electrical resistance includes and with the help of the first current path with the second current path is electrically connected.
  • the residual current circuit breaker also includes a Summation current transformer whose first primary winding of the first current path and the second primary winding of the second current path are formed.
  • Residual current circuit breaker and combined Residual current circuit breaker (RCCB) must be provided with a test device when actuated via a test button with applied mains voltage Residual current is simulated.
  • the residual current circuit breaker must be at Turn off this simulated fault current and the circuit separate. If this is not the case when the test button is pressed In this case the FI-switch is faulty and requires an exchange. Furthermore, the test button must after releasing automatically returned to the starting position and the Test circuit thereby be separated again.
  • the test device usually has a summation current transformer the residual current circuit breaker applied Test circuit winding, a switching element for closing and opening the circuit, an auxiliary switch, a test resistor for current limiting and a test button for tripping a test procedure. Often it will be a separate one Return spring used for the test button.
  • the auxiliary switch is required so that when you press the test button too long an overload of the test resistor is avoided.
  • the auxiliary switch is mechanically with the moving contact coupled to the circuit breaker, so after opening the Contacts of the circuit breaker also the test circuit through the auxiliary switch is forcibly interrupted.
  • the object of the present invention is therefore to to propose a residual current device that easier to assemble and less prone to error.
  • this object is achieved by a residual current circuit breaker with a first stream to the Guide a Nutzstrom, a second current path for recycling the Nutzstroms and a test device, an electrical Includes resistance and with the help of the first Current path with the second current path electrically connected is, wherein the test device is an electrical connection line comprising one end as a spring contact element is designed so that the electrical connection between the first current path and the second current path by overcoming the corresponding spring force can be produced.
  • the invention provides a residual current circuit breaker with a first stream to the Guide a Nutzstrom, a second current path for recycling the Nutzstroms, a summation current transformer whose first Primary winding from the first current path and the second Primary winding are formed by the second current path, and a test device comprising an electrical resistance and with the help of the first current path with the second Current path to form a test circuit electrically is connectable, wherein one of the two primary windings part the test circuit is.
  • the testing device comprises the fault current protective switching device with the summation current transformer, whose one primary winding is part of the test circuit is, an electrical connection line whose one end is designed as a spring contact element, so that the electrical Connection between the first current path and the second current path by overcoming the corresponding spring force can be produced.
  • This can be the residual current device switching device make it even more robust.
  • the residual current circuit breaker according to the invention has a test button, which by the spring force the spring contact in the OFF position, in which the two Currents are not connected to each other via the testing device are held.
  • this test button loosely in a housing portion of the residual current device be guided. This results in a very simple Implementation option for activating the test circuit and it can be used in particular on a special spring for the test button is omitted.
  • the spring contact element may have a circular arc-shaped section exhibit. This allows the test button in their Better reset leadership.
  • the testing device may further comprise an auxiliary switch, with the electrical connection while holding down the test button, d. H. closed test circuit, between the first and second current path is interruptible.
  • This auxiliary switch can be used to ensure that the current-limiting resistor not damaged if the test button is pressed too long becomes.
  • the auxiliary switch with a Cutting connection to an element of the test device electrically be coupled can be coupled. This can be a turn Avoid assembly-friendly and error-prone solder joints.
  • the auxiliary switch and a conductor section have, with which the auxiliary switch by a non-positive Connection to an element of the test device electrically can be coupled.
  • This non-positive connection is one too To prefer soldering for the reasons mentioned.
  • the residual current circuit breaker shown schematically in Figure 1 has a first terminal 4 for a phase conductor 3a and a second terminal 12 for a neutral conductor 3b.
  • the Both conductors 3a and 3b are in a known manner by a Summation current transformer 20 out, where they form the primary windings.
  • the secondary winding of the summation current transformer 20th is guided to a trigger 6 of the residual current circuit breaker. If the opposing currents in the conductors 3a and 3b are different Amount, d. H. there is a fault current, is in the secondary coil of the summation current transformer 20th induces a voltage and the trigger 6 is activated.
  • the testing device simulates a fault current, so that the Residual current circuit breaker, especially the trigger 6 triggers.
  • the testing device essentially consists of a circuit, which connects the phase conductor 3a to the neutral 3b.
  • the test circuit has a resistor 5.
  • the test circuit is closed manually by a test button 2.
  • the test circuit is designed so that the primary winding of the neutral conductor 3b in the summation current transformer 20 at the same time as Test circuit winding is used. For this runs the Test circuit starting from terminal 4 via a test contact wire 1, the resistor 5 and other switching elements for Neutral 3b, which is used as the primary winding through the summation current transformer 20 is guided and ends in terminal 12. In this way becomes the current-carrying primary winding of the summation current transformer 20 simultaneously used as educastrom Vietnamesewicklung. This is an additional test circuit as they is used in conventional devices in the inventive RCCB is not required.
  • the sketchcarddraht 1 thus forms the electrical connection line between terminal 4 and resistor 5. Above In addition, it has a resilient end 1a at the terminal 4 opposite end and thereby serves as a switching element for opening and closing the test circuit. at the same time the test button 2 is passed through the resilient end 1a of the test contact wire 1 held in the OFF position.
  • auxiliary switch 8 which as Leaf spring is executed, arranged.
  • This auxiliary switch 8 is mounted in the housing of the RCD circuit breaker so that it in the ON position of the switch with a first leg 8a, a wire end 5b of the test resistor 5 and with a second leg 8b contacted a neutral contact 9 and thus closes the test circuit, as shown in FIG is.
  • the required contact pressure is determined by the Self-suspension of the auxiliary switch 8 generated.
  • auxiliary switch 8 at the end of its first leg 8a a fork-shaped formation 8 c, the test resistor 5 in positioned in its installation position.
  • the electrical connection can at this junction, for example, by soldering getting produced.
  • this can be a cutting connection be used with the when pressing the Wire 5b of the resistor 5 in the fork-shaped formation 8c of the auxiliary switch 8 achieved a positive connection becomes.
  • the fork-shaped groove 8c at its end smaller than the diameter of the resistance wire 5b formed.
  • Another possibility to connect between the resistance wire 5b and the first leg 8a of the auxiliary switch 8 would be in a non-positive connection.
