Description of drawings
Explain decision design of the present invention in detail by means of the embodiment shown in the accompanying drawing below, these explanations are not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is schematically illustrated switchgear, another position of the switch that this switchgear has the position of the switch of current path according to claim 1, as to be used for neutral conductor and is used for the current path of phase conductor; And
Fig. 2 to Fig. 9 shows the different execution modes of the wire turn of a part of being arranged to described switching device with different views.
Embodiment
Figure 1 illustrates the switchgear 1 of band housing 2, another position of the switch 5 that described switching device has the position of the switch 4 of the current path that is used for neutral conductor N and is used for the current path of phase conductor P with switching device 3.The current path of described neutral conductor N and phase conductor P makes power supply and load, especially electrical appliance to be connected with each other in distolateral schematically illustrated binding post 6 and 7 of being directed to respectively.Contactor, relay and their equivalent and all belong to one pole or multipole switch equipment such as the protection switch equipment of line protection switch.
The position of the switch 4 of described neutral conductor N is made up of fixed contact 8 and moving contact 9.Described fixed contact 8 is placed on the fixing contact support 10, and this contact support is the part of G shape current path 11.Described current path 11 forwards in the conductor 12 that intersects with it in the one side, thereby forms the wire turn 11,12 of integral type.Described conductor 12 is supported on the selected location regularly and is embodied as stairstepping with respect to housing by holding device 13.
The moving contact 9 of the position of the switch 4 of described neutral conductor N is positioned on the moving contact supporting member 14, figure 1 illustrates its make position.Wherein, described conductor 12 is near described moving contact supporting members 14 and be arranged essentially parallel to the extension of described moving contact supporting member ground, and that described current path 11 is arranged to described conductor 12 and described moving contact supporting member 14 is separated by a distance.Described moving contact supporting member 14 is supported on the axle 15 in rotating mode and can be switched to the open-circuit position shown in the dotted line thus.Described moving contact supporting member 14 and flexible wire 16, especially twisted wire is connected, and described lead is connected conductively at the current path of one side with neutral conductor N.
By means of on the entity corresponding to the circuit breaker 18 and the thing followed (shown in broken lines) the release force F1 of another position of the switch 5 at this, can be indirectly (with shown in the solid line) steering force F3 be applied to described moving contact supporting member 14 by actuation unit 17.Described actuation unit 17 is embodied as switching mechanism at this, especially latching device.Described release force F1 act on simultaneously be provided with another moving contact 20 and with described moving contact supporting member 14 another moving contact supporting member 19 by coaxial supporting on.Described moving contact supporting member 14,19 also can be by different axle supportings.Another position of the switch 5 another fixed contact 22 on being placed in another fixed contact supporting member 21 that is used for the current path of described phase conductor P constitutes.The current path of described phase conductor P extends through an ear shape zone until the arc control device 23 that schematically illustrate in described another fixed contact supporting member 21 1 sides.The current path of described phase conductor P has (corresponding to described flexible wire 16) twisted wire equally in described moving contact supporting member 19 1 sides, described twisted wire allows described moving contact supporting member 19 keeping switching to the open-circuit position from make position under the situation about being connected with the conduction of the current path of described phase conductor P.
In of the use of described switchgear 1 according to regulation, schematically in the current path of described phase conductor P, flow through described another fixed contact supporting member 21 with the electric current I shown in the electric current arrow, flow through another position of the switch 5, flow through described another moving contact supporting member 19 and finally flow through described twisted wire and arrive the part fixing of described phase conductor P with respect to housing with described two contacts 20,22.Make circuit complete by means of (unshowned) electrical appliance between the initiating terminal of clearing end that can be connected described phase conductor P and described neutral conductor N at this, may be by described flexible wire 16, described moving contact supporting member 14, the described position of the switch 4 that has corresponding contact 8,9, described fixed contact supporting member 10 and final thereby make by described wire turn 11,12 with the backflow of the electric current I of symbolic representation.
If realize the control or the disconnection of described circuit breaker 18 under service conditions and failure condition, so described release force F1 just acts on described another moving contact supporting member 19 and the described actuation unit 17 with onesize.Therefore, pivot to the process of its open-circuit position from its make position at described another moving contact supporting member 19, actuation unit 17 as switching mechanism design is just discharged by described release force F1, makes described moving contact support 14 owing to the open-circuit position of tending to switch to from its make position it in this is unshowned (such as the switch spring form) energy reservoir and by the steering force F3 that it provides.Here, described switch spring can be the part of described switching mechanism.
Support the disconnection of described another position of the switch 5 by the electrokinesis that provides based on the described sense of current on described another fixed contact supporting member 21 and described another moving contact supporting member 19.Wherein, described electrokinesis works with the form of impact F2, rushes open the member that adjacent setting and stream have reverse current up to it.Because described electric current I, as shown in Figure 1, must be through the route of a U-shaped in the zone of described another position of the switch 5, thus described another moving contact supporting member 19 by result from wherein and not the magnetic field of same-action rush open described another fixed contact supporting member 21.
Opposite with current lead-through in the current path of described phase conductor P is, electric current I pass through according to the U-shaped design of as shown in Figure 1 described fixed contact supporting member 10 that the described position of the switch 4 is close to conduction point-blank and the described wire turn 11,12 of process after them.Wherein, the conductor 12 of a described part that is embodied as wire turn 11,12 is with parallel with described moving contact supporting member 14 and extend apart from the less modes of described moving contact supporting member 14 distances, and this causes the sense of current in the same way.Because the parts of switching in the same way attract each other owing to the magnetic field of same function, so can utilize the electrokinesis of standard at this.But, this electrokinesis shows by coercive force F4, and it has the opposite effect in this wise to described steering force F3, makes to have stoped described steering force F3.
Therefore, stop the effect of described steering force F3 to cause comparing the disconnection that the described position of the switch 4 postpones in time with the manipulation time point of described another contact support 19.By this current lead-through targetedly, electrokinesis, as its as described in phase conductor P as described in another position of the switch 5 be to be used on the contrary and as coercive force or die locking force F4 with the performance of impact F2 form.This measure cause the described position of the switch 4 since moving contact supporting member 14 with respect to the hysteresis of another moving contact supporting member 19 and just disconnection another position of the switch 5 after, therefore and at first realize the disconnection of load-carrying described phase conductor P, secondly be the disconnection of not load-carrying described neutral conductor N.
Be accordingly therewith, switching on and off in the process of described switchgear 1, the electric arc that produces in load running only appears at another position of the switch 5 that just is provided with the described phase conductor P of arc control device 23 originally under the situation that keeps described action sequence, so that eliminate electric arc as quickly as possible.Owing to there is not electric arc to produce in the described position of the switch 4, therefore, the structure of the current path of described neutral conductor N is compared in a simple manner with the structure of the current path of described phase conductor P and is realized; Have littler contact volume, slider material with low cost, littler conductors cross in addition and avoided using independent circuit breaker and independent arc control device.
As long as can produce on described two position of the switch 4 or 5 described contact 8 and 9 and described contact 20 and 22 between electric current narrow road zone in so-called electric current narrow road power, electrokinesis just only acts on described another position of the switch 5 of the described position of the switch 4 of described neutral conductor N and described phase conductor P with limited scale.As long as the current lead-through that part takes the shape of the letter U is by the electric current narrow road zone on the described position of the switch 4, and produce the electric current of the reverse flow of not expecting cause impact thus, just not only compensate described impact by means of the described coercive force F4 that produces by described conductor 12, but also guarantee a synthetic and power that determined described time-delay.
Therefore, the size of described coercive force F4 depends on the size of electric current I, and to be switched electric current I is high more, and described coercive force F4 is just big more, because current strength represents described moving contact supporting member 14 is strapped in the measuring of intensity in the magnetic field on the described conductor 12.Equally, described coercive force F4 is determined by described length and the spacing that is roughly parallel to the conductor 12 that described moving contact supporting member 14 ground that are in the close position are provided with; Described conductor 12 be parallel to described moving contact supporting member 14 extend longly more and described member between the noncontact spacing more little, described coercive force F4 is just big more.Undesirable attendant phenomenon that may produce in switching process (shake, heating or the welding of the contact 8,9 of for example described position of the switch 4) can be avoided by the suitable selection to above-mentioned parameter.
Be closed described two position of the switch 4,5 again, just described two moving contact supporting members are moved to make position separately from the open-circuit position, can be for example by means of switch knob or by this unshowned one may Long-distance Control the reset pulse of resetting means realize the hand-reset of actuation unit 17.Wherein, the structure of described switchgear 1 can design like this, make in the connection process of the described moving contact supporting member 14 of the described position of the switch 4, be arranged on described another fixed contact 22 with another moving contact 20 of another moving contact supporting member 19 and compare, its moving contact 9 is placed to the make position of the fixed contact corresponding with it 8 earlier.For this reason, the described fixed contact 8 of the described position of the switch 4 and the contact spacing between the moving contact 9 (even under situation of the tolerance of scaling loss contact and structure decision) are confirmed as structurally less than the fixed contact 20 of described another position of the switch 5 and the contact spacing between the moving contact 22.
In Fig. 2 and Fig. 3 and Fig. 4 and Fig. 5, show the wire turn 11,12 of a part that is restricted to described switching device with plane graph and perspective view.Wherein, described wire turn 11,12 has the lead 12 of two-stage step bending and the two-stage current path 11 of bending counterclockwise as the integral type unit, is provided with fixing contact support 10 at the latter's free end.Wherein, described wire turn 12 or its each building block can be provided with regularly with respect to housing.Described current path 11 is constituted as roughly G shape, and can be fabricated to the bending ram parts of for example being made by the stock of described current path 12 as illustrated in fig. 3.Described according to wire turn 11,12 the position and shape with respect to described moving contact supporting member 14 as the given sense of current of Fig. 1 guaranteed by as described in the electrokinesis that causes of coercive force F3.
In Fig. 6 to Fig. 9, show other design of described wire turn 11,12 with different views.Wherein, as shown in Figure 6 and Figure 7, the structure that described current path 11 has intimate S shape, and as Fig. 8 and shown in Figure 9, current path 11 is configured to L shaped.
Can the invention of above explaination be summarized as follows:
The switchgear 1 that disconnects for the time-delay that the described position of the switch 4 in a kind of current path of guaranteeing neutral conductor in simple mode is provided is provided with like this, make described moving contact supporting member 14 corresponding with described conductor 12 in make position, this conductor keeps conduction to be connected with described fixed contact 10 and has and described moving contact supporting member 14 sense of current in the same way, the effect that makes described energy reservoir act on the power of the steering force F3 on the described moving contact supporting member 14 is like this weakened by the effect of the power of the electronic coercive force F4 that is determined by electric current, and realizes thus switching to the time-delay of described open-circuit position.
