Definitions

  • the invention relates to a multi-pole switching device in which each Polate has at least one input terminal and an output terminal, which are electrically connected to each other via a connecting line and at least one measuring device for detecting the current flowing in this connection line is provided, wherein at least one Polate is provided in whose connecting line is a switching contact with a fixed and a movable contact piece is connected, which contact pieces are electrically conductive, resulting between the contact pieces arcs of these contact pieces leading rails connect.
  • a single-phase residual current circuit breaker according to the preamble of claim 1 with a neutral connected is described, wherein the housing has two parallel chambers.
  • a summation current transformer In the first chamber, a summation current transformer, a trigger relay connected thereto and a neutral circuit and in the second chamber, a phase conductor circuit comprising a switching contact and a spark-quenching chamber and a mechanism for manually switching on and off the switch housed.
  • the neutral circuit has leads disposed immediately adjacent to one another and so that the currents flowing in them flow in opposite directions, thereby causing the magnetic fields generated by these currents to compensate each other, thus avoiding any influence on the trigger relay.
  • the disadvantage here is that the path-movement of the light boulder is not accelerated.
  • this is achieved in that the connecting line of at least one Polate, which is adjacent to the switching contact having Polate, at least partially so guided that the magnetic field generated by the current flowing in their current magnetic field amplifies that magnetic field, which in the of the contact pieces and the area circumscribed to the rails is caused by the current flowing in the presence of an arc between the contact pieces and the rails in the rails and the arc.
  • the connecting line between the input and output terminal of a Polate is an already existing component of the switching device, which only has to be slightly modified to implement the invention.
  • This modification is in the insertion of a line piece, such as e.g. Conductor rope, or even if such is already present in the connection line, in the change in the spatial arrangement, which may, if necessary, be accompanied by a slight extension of this conductor cable.
  • a line piece such as e.g. Conductor rope
  • the connecting line runs at least in sections approximately parallel to the area circumscribed by the contact pieces and the rails in the region of their boundary.
  • the magnetic field caused by the current in the connecting line thus runs in the same direction as the magnetic field generated by the current in the rails and the arc, so that the gain of this magnetic field to be achieved is achieved particularly effectively.
  • the connecting line is designed in the form of a conductor loop and arranged so that the surface spanned by it lies approximately parallel to the circumscribed by the contact pieces and the rails surface and this area covers at least partially.
  • the surface defined by the conductor loop covers the surface circumscribed by the contact pieces and the rails, at least in the region of the contact pieces and in the region of the sections immediately adjacent thereto.
  • the multi-pole switching device according to the invention with two pole sections can be designed as a combination of circuit breaker and residual current circuit breaker, in which the previously general and not on a particular multi-pole Switching device described limited invention principle is realized.
  • the first provided for connecting the phase conductor of a single-phase power supply network Pol the measuring devices of a circuit breaker (overcurrent detector and short-circuit current detector) and one of these measuring devices via a switching mechanism controlled switching contact and to the fixed or the movable contact piece this switching contact subsequent, electrically conductive rails and has the second provided for connecting the neutral conductor of a single-phase power supply network Polate the components of a fault current detection circuit (summation current transformer and connected to the secondary winding evaluation circuit).
  • the connecting lines of both this neutral pole path and the phase conductor Polate are guided through the toroidal core of the summation current transformer and the evaluation device acts on the arranged in the phase conductor Polumble switching mechanism.
  • the connecting line of the neutral conductor Polate is formed by a conductor, which is designed in the form of a conductor loop and arranged so that the surface spanned by it is approximately parallel to the area circumscribed by the contact pieces and the rails surface and this area covered at least in the region of the contact pieces and in the region of these immediately adjacent sections of the rails.
  • This force F shifts the arc 3 in their direction, ie to the right in the representation according to FIG.
  • switching devices see schematic illustration in Figure 2
  • Such a device comprises a plurality of mutually approximately parallel platelets 7, which are aligned approximately normal to the arc 3. If the arc 3 enters such a spark quenching chamber 6, it is subdivided by the platelets 7 into a multiplicity of series-connected partial arcs, which are present between the platelets 7.
  • a voltage necessary to maintain a series connection of a plurality of partial arcs is higher than the voltage required to maintain a single arc having the same total length. If the voltage between the rails 1, 2 is lower than the sum of the sustaining voltages of the partial arcs, the arc 3 in the spark-quenching chamber 6 can be extinguished and the electrical connection between the rails 1, 2 can be interrupted. The in-motion of the arc into the spark-quenching chamber 6 is achieved by the above-discussed physical fact of the generation of a force F on the arc 3 caused by the magnetic field of current flow in the rails 1,2.
  • a current-carrying conductor 10 is provided which extends in sections approximately parallel to the area A 1 circumscribed by the contact pieces 8, 9 and the rails 1 , 2 (see FIGS. 3 a, b, c).
  • the current flow in this conductor 10 generates a magnetic field represented by the symbols 4 ', 5', which corresponds to the magnetic field prevailing within the area A 1 superimposed. If the current flow direction in the conductor 10 is selected in the manner shown in FIG. 3a, b, c, the magnetic field in the area A 1 is amplified.
  • the exact course of the conductor 10 is to be chosen so as to give the discussed effect of magnetic field amplification.
  • This conductor 10 can therefore be arranged anywhere in the area outside the area A 1 (see Fig. 3a, b, c). The closer it is to the surface A 1 , the greater, of course, the magnetic field in this area A 1 reinforcing effect, which is why it is preferably located in the region of the boundary, for example at a short distance lying exactly over one of the rails 1.2.
  • a conductor loop 11 is used, which is arranged so that the surface A 2 spanned by it is approximately parallel to the contact pieces 8, 9 and the rails 1, 2 circumscribed area A 1 and this area A 1 at least partially covered.
  • the conductor loop 11 is therefore coplanar over the surface A 1 .
  • the magnetic field driving the arc 3 in the direction of the spark-quenching chamber 6 is amplified. Outside of this coverage area, the magnetic field generated by the conductor loop 11 attenuates the magnetic field generated by rails 1, 2 and arc, which in turn leads to a lower running speed of the arc 3 in this area.
  • this region lying outside the coverage area of the areas A 1 and A 2 is already in the spark-quenching chamber 6, that is to say in an area in which the arc 3 is already shortly before its extinction and therefore no longer further must be moved.
  • the number of turns of the conductor loop 11 can be selected arbitrarily high, but since only small forces are required for further movement of an arc 3, it is sufficient, as shown in Fig.4a, b, to provide a single winding.
  • the invention uses the provision of a discussed conductor 10 and a discussed conductor loop 11 to increase the running speed of an arc 3 and is to apply this principle in a multi-pole switching device.
  • An example of such a multi-pole switching device is shown in FIGS. 5 to 9, to which reference is made below:
  • This multi-pole switching device is bipolar and designed as a combination of circuit breaker and residual current device.
  • Each pole section 12, 13 has at least one input terminal 14, 14 'and one output terminal 15, 15'.
  • the input terminal 14,14 'of each Polate 12,13 is electrically connected to the output terminal 15,15' of this Polate 12,13 by a connecting line.
  • the input terminal 14 is connected via the bimetallic strip 16 and via a flexible conductor cable 17 to the contact bridge 18, which carries the movable contact piece 9. in the switched state is this movable contact piece 9 on the fixed contact piece 8, which is fixed to the contact piece carrier 19.
  • This carrier 19 is connected to the first end of the coil 20, whose second end is connected via a further conductor 21 to the output terminal 15.
  • the coil 20 has an armature slidably mounted in its longitudinal direction, which from the magnetic field of the coil 20 - if this has a sufficient strength due to a short-circuit current is pressed against the contact bridge 18 so that the switching mechanism 26 is triggered and pivots the contact bridge 18 of this becomes. Ultimately, the movable contact piece 9 is lifted from the stationary contact piece 8 by these operations.
  • the coil 20 with the movable armature forms the short-circuit current detector of the circuit breaker part of the present switching device.
  • the bimetal strip 16 is heated by the current flowing through it and thereby bends so that its connected to the conductor cable 17 end is pivoted to the right. If too high a continuous current, this bending of the bimetallic strip 16 to such an extent that pivots over the bracket 22, the contact bridge 18 and the movable contact piece 9 is lifted from the fixed contact piece 8.
  • the bimetallic strip 16 thus forms the overcurrent detector of the circuit breaker part of the present switching device.
  • electrically conductive rails 1, 2 are provided, which adjoin the contact pieces 8, 9 and serve to conduct arcing arcs between the contact pieces 8, 9 away from them.
  • electrically conductive rails 1,2 are provided, which adjoin the contact pieces 8, 9 and serve to conduct arcing arcs between the contact pieces 8, 9 away from them.
  • a plurality of spaced apart mutually parallel electrically conductive plate 7 is provided, which forms a spark-quenching chamber 6 with already discussed above operating principle.
  • the connecting line between the input terminal 14 'and the output terminal 15' is formed by a continuous conductor cable 23.
  • This conductor cable 23 and the previously mentioned, the coil 20 of the first pole section 12 with its output terminal 15 connecting conductor 21 are guided by the toroidal core 24 of a summation current transformer.
  • the secondary winding of this summation current transformer is connected to an electronic unit (indicated by the outline 25 of the printed circuit board carrying this electronics), which electronics evaluate the signal supplied by the summation current transformer.
  • the electronics are further connected to the switching mechanism acting on the movable contact piece 9, so that they can cause the opening of the interruption contact 8.9 of the first pole section 12 when an unacceptably high difference between the currents in the conductor cables 21 and 23 is detected.
  • the second Polate 13 thus included the components of a residual current detection circuit formed of a summation current transformer and a secondary winding of its connected evaluation circuit. This evaluation circuit can of course be realized in another form, for example by a permanent magnet release.
  • the conductor line 23 forming the connection line between the input terminal 14 'and the output terminal 15' is in the form of a conductor loop having a turn.
  • This conductor loop is arranged so that the surface A 2 spanned by it lies approximately parallel to the area A 1 circumscribed by the contact pieces 8, 9 and the rails 1, 2 , and covers this area A 1 in regions.
  • FIGS. 8 and 9 This regional overlapping can be seen in particular from FIGS. 8 and 9, in which all housing parts of the switching device, in particular also the partition wall lying between the two pole sections 12, 13, have been omitted.
  • the area in which the areas A 1 and A 2 overlap is here in the area of the contact pieces 8, 9 and in the area of the immediately adjacent sections of the rails 1, 2 .
  • the first Polate 12 is provided for connection of the phase conductor L of a two-pole voltage supply network, the second Polate 13 for connecting the neutral conductor N of this voltage supply network.
  • the invention is by no means limited to the particularly preferred embodiment shown in FIGS. Its underlying principle is, in a multipole switching device designed in any way the above discussed with reference to Fig.1-4b principle of increasing the arc speed with the help of an already existing connection line Polaus, adjacent to a one switching contact with subsequent Arc extinguishing device comprising Pol schedule is to realize.
  • the connecting line does not have to have the shape of a conductor loop with only one turn, it could also be provided several turns. However, it is also sufficient in the sense of FIG. 3a-c to provide only a portion of the conductor loop provided in FIGS.
  • the remaining sections of the conductor cable 23 can be laid arbitrarily.
  • the input terminal 14 'of the neutral pole section 13 at the lower edge of the device ie adjacent to the input terminal 14 of the phase conductor Polate 12 to arrange. It is sufficient to effect the magnetic field amplification in question, to lay the conductor cable 23 in the form of in Fig.9 with 23 'designated upper branch or designated by 23 "lower branch of the conductor loop.
  • the application of the subject invention is not limited to switching devices in which circuit breaker and residual current device function are combined. Rather, it is possible to realize the inventive principle in a multi-pole, only one of the two circuit breaker functions having switching device (three- or four-pole circuit breaker or four-pole residual current circuit breaker, each for a three-phase system).
  • the switching device according to the invention is connected in the necessary manner with the voltage supply network or with the forwarding to the consumers, is on the housing of the switching device in the range of each terminal 14,15; 14 ', 15' printed, .which line to the respective terminal 14, 15; 14 ', 15' is to be connected.
