Definitions
- the invention relates to a multi-pole switching device, in which each pole section at least has an input terminal and an output terminal, which via a Connection line are electrically connected to each other and at least one Measuring device for detecting the current flowing in this connecting line is provided, at least one pole section being provided, in the connecting line thereof a switching contact with a fixed and a movable contact piece switched is to which contact pieces are electrically conductive, between the contact pieces Connect arcs that arise from these contact pieces to conductors.
- the connecting line at least one Pole path, which is adjacent to the pole path having the switch contact at least is performed in sections so that that generated by the current flowing in it during operation Magnetic field reinforces that magnetic field which is in the contact pieces and the Rails circumscribed area of which when there is an arc between the Contact pieces or the rails in the rails and the current flowing in the arc is caused.
- the connecting line between the input and output terminal of a pole section is a already existing component of the switching device, which is only for realizing the invention needs to be slightly modified.
- This modification lies in the insertion of a Line piece, e.g. Conductor rope, or if such in the connecting line already exists, in changing its spatial arrangement, which if necessary, can be accompanied by a slight extension of this conductor cable. All in all, however, all of these measures result in only a minimal additional material expenditure and can easily be built into existing designs from Switchgear can be installed.
- the connecting line at least in sections approximately parallel to that circumscribed by the contact pieces and the rails Area in the area of which the border runs.
- the magnetic field caused by the current in the connecting line thus runs in the same direction as that generated by the current in the rails and the arc Magnetic field, so that the amplification of this magnetic field to be achieved is particularly effective is achieved.
- the connecting line in the form of a conductor loop and so is arranged that the area spanned by it approximately parallel to that of the contact pieces and the area circumscribed by the rails, and this area at least in some areas covered.
- the conductor loop spanned area is the area circumscribed by the contact pieces and the rails at least in the area of the contact pieces and in the area of those immediately adjacent to them Sections of the rails covered.
- Another object of the present invention is to provide a multi-pole switching device two pole sections designed as a combination of miniature circuit breaker and Residual current circuit breaker to specify, in which this has so far been general and not on certain multi-pole switching device realized limited inventive principle is.
- the first one for connecting the phase conductor single-phase voltage supply network provided pole section the measuring devices a circuit breaker (overcurrent detector and short-circuit current detector) and a switching contact controlled by these measuring devices via a switching mechanism and to the fixed or the movable contact piece of this switching contact subsequent, electrically conductive rails and has the second for connecting the Neutral conductor of a single-phase voltage supply network provided the pole section Components of a residual current detection circuit (summation current transformer and on its Secondary winding connected evaluation circuit).
- the connecting lines both this neutral conductor pole section as well as the phase conductor pole section are through the toroid of the total current transformer and the evaluation device acts on the in the Phase conductor pole path arranged switching mechanism.
- the connecting line of the neutral conductor pole section is formed by a conductor cable which in Shape of a conductor loop and is arranged so that the spanned by it Surface approximately parallel to the surface circumscribed by the contact pieces and the rails lies and this area at least in the area of the contact pieces and in the area of these immediately adjacent sections of the rails covered.
- 1 and 2 denote electrically conductive, current-carrying rails, between which an arc 3 burns.
- the current through the rails 1,2 and Arc 3 generates an electromagnetic field, the direction of which is represented by symbols 4 and 5 is shown.
- the arc 3 is located within this field current-carrying conductor on which this electromagnetic field exerts a force F. This force F shifts the arc 3 in its direction, that is to the right in the Representation according to FIG. 1.
- a spark extinguishing chamber 6 As shown in Fig.1.
- Such a facility comprises a plurality of approximately parallel plates 7 which are approximately normal to Arc 3 are aligned. If the arc 3 runs into such a spark quenching chamber 6 into the plate 7 into a plurality of partial arcs connected in series divided, which are pending between the plates 7.
- a current-carrying conductor 10 is provided, which in sections runs approximately parallel to the area A 1 circumscribed by the contact pieces 8, 9 and the rails 1 , 2 (cf. FIGS. 3a, b, c).
- the current flow in this conductor 10 generates a magnetic field represented by the symbols 4 ', 5', which is superimposed on the magnetic field prevailing within the area A 1 . If the current flow direction in the conductor 10 is selected in the manner shown in FIGS. 3a, b, c, the magnetic field in the area A 1 is amplified.
- the exact course of the conductor 10 is to be selected so that the discussed effect of the magnetic field amplification results.
- This conductor 10 can therefore be arranged anywhere in the area outside the area A 1 (cf. FIGS. 3a, b, c). The closer it is to the area A 1 , the greater is of course the effect which strengthens the magnetic field in this area A 1 , which is why it is preferably arranged in the area of the boundary, for example at a short distance exactly above one of the rails 1 , 2.
- a conductor loop 11 is used, which is arranged such that the area A 2 spanned by it is approximately parallel to that of the contact pieces 8, 9 and the rails 1, 2 circumscribed area A 1 and this area A 1 at least partially covers.
- the conductor loop 11 is therefore coplanar over the area A 1 .
- the magnetic field driving the arc 3 in the direction of the spark quenching chamber 6 is strengthened. Outside of this coverage area, the magnetic field generated by the conductor loop 11 weakens the magnetic field generated by rails 1, 2 and arc, which in itself leads to a lower running speed of the arc 3 in this area.
- this area 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 about to be extinguished and therefore no longer in any case must be moved.
- the cheapest design variant of the conductor loop 11, taking into account the information just given, is of course to cover the entire area A 1 (see FIG. 4b).
- the number of turns of the conductor loop 11 can be chosen to be as high as desired, however only small forces are required to move an arc 3, it is sufficient as shown in Fig.4a, b to provide a single winding.
- the invention relies on the provision of a discussed conductor 10 and a discussed Conductor loop 11 to increase the running speed of an arc 3 and is in applying this principle to a multi-pole switching device.
- An example of a such a multi-pole switching device is shown in Figs. 5-9, to which reference is made below is taken:
- This multi-pole switching device has two poles and is a combination of a circuit breaker and residual current circuit breaker.
- Each pole section 12, 13 has at least one Input terminal 14, 14 'and an output terminal 15, 15'.
- the input terminal 14, 14 ' each pole section 12, 13 is connected to the output terminal 15, 15 'of this pole section 12, 13 Connection line electrically connected.
- the coil 20 has an armature which is displaceable in its longitudinal direction and which from the magnetic field of the coil 20 - if this is due to a short-circuit current has sufficient strength - is pressed against the contact bridge 18 so that the Switching mechanism 26 triggered and by this the contact bridge 18 is pivoted. Ultimately, through these processes, the movable contact piece 9 becomes stationary Contact piece 8 lifted off.
- the coil 20 with the movable armature forms the Short circuit current detector of the circuit breaker part of the present switching device.
- the bimetallic strip 16 is heated by the current flowing through it and bends so that its end connected to the conductor cable 17 is pivoted to the right. If the continuous current is too high, this bend of the bimetal strip 16 leads to the extent that that the contact bridge 18 is pivoted via the bracket 22 and the movable contact piece 9 is lifted off the fixed contact piece 8.
- the bimetallic strip 16 thus forms the Overcurrent detector of the circuit breaker part of the present switching device.
- This pole section 12 is thus two the current through this connecting line measuring devices and a switch contact (fixed and movable Contact piece 8.9), on which said two current measuring devices act, i.e. can open it.
- electrically conductive rails 1, 2 are provided, which contact the contact pieces Connect 8.9 and serve to create arcs between the contact pieces 8.9 to lead away from these.
- electrically conductive rails 1, 2 In the space between these rails 1, 2 there is a large number of spaced parallel electrically conductive plates 7 are provided, which forms a spark extinguishing chamber 6 with the functional principle already discussed above.
- the electronics are also included connected to the moving contact piece 9 switching mechanism, so that it upon detection of an impermissibly high difference between the currents in the conductor cables 21 and 23 cause the interruption contact 8, 9 of the first pole section 12 to open can.
- the second pole section 13 thus contained the components of a fault current detection circuit, formed from a summation current transformer and one of them Secondary winding of connected evaluation circuit. This evaluation circuit can naturally in a different form, for example by means of a permanent magnet release, be realized.
- the conductor cable 23 forming the connecting line between the input terminal 14 'and the output terminal 15' is designed in the form of a conductor loop which has one turn.
- This conductor loop is arranged in such a way that the area 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 some areas.
- the first pole section 12 is for connecting the phase conductor L of a two-pole voltage supply network, the second pole section 13 for connecting the neutral conductor N this Voltage supply network provided. Occurs when the switch contact opens Arc between its contact pieces 8.9 or subsequently between them Components connecting rails 1,2, this arc ensures that initially also current still flows in neutral conductor N and thus in conductor cable 23. This current flow therefore leads for the amplification of the magnetic field discussed in the beginning, which in the Contact pieces 8.9 and the rails 1.2 circumscribed area in the presence of a Arc between the contact pieces 8.9 and the rails 1.2 from in the rails 1,2 and the arc flowing current is caused.
- the invention is by no means limited to that shown in FIGS. 6-9, particularly preferred Embodiment limited.
- the principle on which it is based is that of an in any designed multi-pole switching device that the above with reference to Fig.1-4b discussed principle of increasing the arc running speed with the help of an anyway existing connecting line of a pole path that is adjacent to a Switching contact with subsequent pole section containing arc quenching device lies to realize.
- the connecting line does not have the shape of a conductor loop must have only one turn, several turns could also be provided. It but is also sufficient in the sense of FIGS. 3a-c, only a section of that in FIGS provided conductor loop.
- the remaining sections of the conductor rope 23 can be laid as desired.
- the Input terminal 14 'of the neutral conductor pole section 13 at the lower edge of the device that is to be arranged next to the input terminal 14 of the phase conductor pole section 12. It is enough to effect the magnetic field reinforcement in question, the conductor cable 23 in the form of in FIG. 9 with the 23 'upper branch or the lower branch with 23 " Lay the conductor loop.
- the application of the present invention is not limited to switching devices, where circuit breaker and residual current circuit breaker functions are combined. Rather, it is possible to use the principle according to the invention with a multipole, only one of the two circuit breaker functions (three- or four-pole Miniature circuit breakers or four-pole residual current circuit breakers, each for one three-phase three-phase system).
- a switch contact with an arc extinguishing device is not only in one of the Pole sections, but at least in all phase conductor pole sections, usually also in the Neutral conductor pole section may be provided.
- This prevents the application of the objective Not invention, also here the connecting line of one of the pole sections in one of the The ways discussed above are such that the current flow in this connecting line that magnetic field is amplified, the one between the rails 1, 2 of an adjacent one Pole path moving arc moving.
- the neutral conductor N can also be designed to be interruptible here, i.e. in its pole section 13 a switch contact corresponding to the design of the first pole section 12 can be installed.
