Below to being described in detail according to adjusting device of the present invention.In the accompanying drawing:
Fig. 1 represents a simple schematic diagram of adjusting device that is used to regulate the moving contact that moves a vacuum circuit-breaker;
Simple schematic diagram when Fig. 2 represents that adjusting device shown in Figure 1 is in open position;
Simple schematic diagram when Fig. 3 represents that adjusting device shown in Figure 1 is in the close position;
Fig. 4 represents the three-dimensional simple schematic diagram of an adjusting device;
Fig. 5 represents an another kind of execution mode that is used to regulate the adjusting device that moves a moving contact.
Fig. 1 expresses the adjusting device 1 of the moving contact 2a of a switching device that is used to regulate a vacuum circuit-breaker 3 forms that illustrate equally briefly of moving briefly.At this, the coupling device by coupling bar 4 forms that are connected with unshowned drive unit in Fig. 1 makes two crescent slide plates 5 that are arranged in parallel and 6 motions.For this reason, coupling bar 4 for example is connected by means of an axle that extends between these two crescent slide plates 5,6 at a tie point 14 places with crescent slide plate 5 and 6 swingably.In addition, crescent slide plate 5,6 in its bottom one fixedly point of rotation place rotatably for example be connected with an outer casing member that surrounds the shell of adjusting device 1.In Fig. 1, express crescent slide plate 5 is removed before coupling bar 4, so that can see coupling bar 4 and another crescent slide plate 6 that is positioned at crescent slide plate 5 back.According to Fig. 1, crescent slide plate 5 and 6 respectively has a gathering sill 7, and wherein, this gathering sill 7 is made up of three adjacent section 7a, 7b and 7c.At this first guide section 7a of shaping-orientation groove 7 at first, this first guide section 7a extends obliquely with respect to a so-called centre portion 7b who adjoins with it.In the represented view of Fig. 1, the pin 8 of a guiding in gathering sill 7 mediates, and centre portion 7b along continuous straight runs extends, and that is to say no any gradient.That adjoin mutually with this centre portion 7b at last is another guide section 7c that extends obliquely with respect to centre portion 7b again.
Described pin 8 by the guiding of crescent slide plate is connected with a drive rod 9 again, and this drive rod 9 is connected with the moving contact 2a of vacuum switch 3 with its other end.This drive rod 9 for example imports in the shell 11 of vacuum switch 3 by means of a bellows 10.In addition, one should prevent that pin 8 links to each other with this pin 8 transverse to the fixed lever 12 of the adjusting direction motion of moving contact 2a.For this reason, correspondingly the length of designs fix bar 12 makes pin 8 can seem to be similar to straight line around the circular arc of the point of rotation 19 motions thereon.
Although in Fig. 1, expressed project organization, also can realize only having the expansion structure of a crescent slide plate 5 within the scope of the present invention with two opposed abreast crescent slide plates 5,6.
To set forth operation principle below according to the adjusting device of Fig. 1.
Expressing moving contact 2a in Fig. 1 at first is in the position between open position and make position.Pin 8 is in the centre position among the centre portion 7b of gathering sill 7.
For the moving contact 2a of closed vacuum switch 3, (unshowned in the drawings) drive unit that is connected with coupling bar 4 moves this coupling bar 4 along a first direction of representing with arrow 13.This coupling bar 4 round the fixing point of rotation 16 along the direction upset crescent slide plate of expressing by second arrow 15 5,6.Make thus crescent slide plate 5,6 and and then also make each gathering sill 7 with respect to pin 8 motion, therefore pin 8 is among the second guide section 7c of gathering sill 7, because fixed lever 12 stops it to carry out transverse movement, therefore pass through the shape of gathering sill 7 this pin of direction to upper edge vacuum circuit-breaker 3.By drive rod 9 this moving upward is delivered on the moving contact 2a, therefore moving contact is moved on its make position.In Fig. 2, represented this situation.Can see that in the figure moving contact 2a is in its make position and pin 8 is in the second place in the gathering sill 7.
In order to disconnect moving contact 2a, described drive unit moves coupling bar 4 with the 3rd direction that arrow 17 is represented along one in Fig. 1, makes crescent slide plate 5 and 6 the 4th direction that arrow 18 is represented upset around the described point of rotation 16 along a usefulness thus.Gathering sill 7 is passed with respect to pin 8 again thus, and this pin 8 at first turns back to the centre portion 7b from the second guide section 7c, then turns back among the first guide section 7a and be in it at last to be equivalent in the primary importance that moving contact 2a disconnects fully.This state at length shows in Fig. 3.In a word, in the disconnection process pin and and then also have moving contact 2a at first to carry out one to disconnect motion, remain in the centre position then and next carry out another and disconnect motion.
In order to extinguish the electric arc that when disconnecting moving contact 2a, between moving contact 2a and fixed contact 2b, forms reliably, need when disconnecting this moving contact 2a, implement above-mentioned motion.If moving contact 2a is at once moved to the position that disconnects fully from make position, then can only be difficult to set up and a kind ofly participate in the magnetic field in the extinguish arcs process and can not or just be not enough to extinguish described electric arc.Therefore, pin 8 and also have moving contact 2a at first to move in the middle of it in position by this pin 8 makes it possible to set up fully the described magnetic field that is used for arc extinguishing, afterwards, moving contact 2a just moves in the described position that disconnects fully, vacuum switch 3 locking reliably in this position.At this, cause the above-mentioned of moving contact 2a and move by being delivered to continuous motion on crescent slide plate 5 and 6 by means of coupling bar 4 along arrow 18 from described driver part.Therefore just the structure of the centre portion 7b by design crescent slide plate 5,6 reaches pin 8 is stopped therebetween in the position, rather than realize by the motion that stops crescent slide plate 5,6.
In addition, as from seeing Fig. 1, second guide section 7c of gathering sill 7 designs more smoothly than first guide section 7a of this gathering sill 7.When closed moving contact 2a, reach the resilience that makes this moving contact 2a collide on the fixed contact 2b and suppress moving contact 2a to a great extent thus with not too high speed.
In Fig. 1, express the described first and second guide section 7a, 7c and centre portion 7b and all had a linear or linear tendency.But described equally within the scope of the invention first and second guide section 7a and 7c also can have a kind of for example slight curving tendency.Tendency by a kind of such design can make moving contact 2a disconnect or closing course in the stroke-temporal characteristics curve of process may be also suitable with set quota more accurately.This moving contact 2a is further slowed down when for example the structure of the bending extension by the second guide section 7c is implemented in moving contact and is about to meet fixed contact 2b at this.
Fig. 4 is illustrated in adjusting device 1 described in Fig. 1 with three-dimensional exploded view.Member corresponding to Fig. 1 marks with identical Reference numeral at this.
In Fig. 4, can be clear that, the guiding in the same gathering sill 7 of these two crescent slide plates 5 and 6 slidably of the described same crescent slide plate 5 of two parallel opposed and 6 the structure of having, a pin that in Fig. 4, does not show for clarity 8 (referring to Fig. 1).In addition, the drive rod 9 of (unshowned equally) moving contact 2a (referring to Fig. 1) who is used for vacuum switch 3 and one become the fixed levers 12 of two designs to be connected with pin 8 according to Fig. 4.
At last, Fig. 5 represents the another kind of execution mode of a crescent slide plate.The member corresponding with above-mentioned accompanying drawing still marks with identical Reference numeral.This crescent slide plate 5 and 6 and a great difference is arranged according to the structure of Fig. 1 design.These crescent slide plates 5 and 6 do not have gathering sill, and the guiding profile 20 on its lateral surface only.Define this guiding profile 20 and prevent that pin 8 from skidding off from this guiding profile 20 in side direction by two contact pin 21 and 22.Also pin 8 is abutted on the guiding profile 20 reliably in this embodiment by following manner, promptly, under the shell 11 of vacuum circuit-breaker 3, only for example settle a helical spring 23, convex shoulder 24 mating reactions on this helical spring and the drive rod 9 make this spring that one active force that continues is applied on the pin 8 and pin 8 are pressed onto on the guiding profile 20.Similar with described gathering sill 7 (referring to Fig. 1), this guiding profile 20 has one first guide section 20a and one second guide section 20c and a centre portion 20b.They similarly play according to guiding the effect of this pin 8 in a primary importance (moving contact 2a disconnection) of pin 8 and the stroke-temporal characteristics curve between the second place (moving contact 2a closure).
