Description
Technical field
The present invention relates to be used for the locking mechanism of electric line protection equipment, said equipment has the difference function relevant with circuit-breaker.
Background technology
This locking mechanism generally includes electromagnet, has under the situation of the current imbalance that conductor transmitted through wanting protected electric line, and said electromagnetism physical efficiency triggers the core adjusted of locking mechanism when winding has electric current to pass through.This imbalance uses the helix tube of processing the transformer magnetic circuits to measure through known mode; Said line conductor forms elementary; In the secondary winding of helix tube, obtaining the signal of telecommunication, the said signal of telecommunication shows imbalance and therefore shows in the electric equipment that will protect that leakage of current is arranged.If the unbalanced signal that in secondary, occurs is still available then be sent to actuator subsequently usually after having passed through to guarantee the electronic circuit that signal suitably is shaped.This secondary signal is provided to trigger; This trigger is the lock that can mate again of differential attachment; Said differential attachment is connected to the circuit-breaker trigger mechanism again, and said trigger mechanism is positioned at above-mentioned electromagnet then, and said in this case electromagnet constitutes actuator.
Summary of the invention
Locking mechanism according to the present invention comprises universal driving shaft, and it can present two positions (be respectively and reset position and trigger position), and the triggering of said locking mechanism is delivered to the lock of circuit-breaker.
At last, it comprises that mechanism resets button, and it can move between two settling positions (be respectively and reset position and trigger position), and opposing is returned device and slided during reseting.
The locking mechanism right according to the present invention is characterized in that:
Reset button and can adjust core and be actuated to do parallel translational motion, and for example be arranged so that the motion of sliding part drives universal driving shaft respectively along two rightabouts and along the direction translational motion perpendicular to its direction of motion;
Ratchet is rotatably connected to sliding part through spring element; The said sliding part of said spring element bias voltage; So that set up interlock with mechanical system; Said mechanical system is used to realize the reversible transition of the translational motion of button and sliding part, and said interlock makes sliding part reset in the motion process of position opposing at button towards it and returns the device motion;
During triggering, can adjust core and act on ratchet to interrupt said interlock; Cause on the one hand, returning the position of causing button to turn back under the influence of device to said button to be triggered on the other hand by the said reverse movement that returns device towards the sliding part of retainer bias voltage;
The reverse movement of sliding part and button turn back to the position that is triggered will make be used for can be reverse the mechanical system that becomes of revolution place the position that can restart with the interlock of ratchet.
This structure is very favorable; Because it provides very short kinematic chain; Comprise that dual translation/rotation/translation changes, thereby and its through allowing to reconfigure lock no matter how the position of sliding part guarantees correct operation, like what will describe in detail at the back literary composition.
More specifically; Rotation platen in the middle of the mechanical system of reversible transition that is used for the aggregate motion of button and sliding part comprises; The rotation platen is pivoting between two retainers with respect to housing between two points and is being mechanically connected to button on the one hand and is mechanically connected to sliding part on the other hand through dual interlock in the middle of said; Through being rotatably connected to the triggering member of sliding part, said dual interlock makes the translational motion of button change rotatablely moving of said platen into reversiblely and makes rotatablely moving of said platen change the translational motion of sliding part (4) into reversiblely.Said triggering member (14) and rotation ratchet (16) comprise corresponding profile; Corresponding profile is provided with the first surface part perpendicular to the motion of sliding part (4); Permission is supported along first of said travel direction during reseting; So that an end of said ratchet is placed on the track that can adjust core; Its motion makes ratchet pivot and discharges and support, and returns the reverse movement that causes sliding part and button under the influence of device they corresponding, and the aggregate motion of triggering member and intermediate disc makes first surface partly be placed in each other once more and faces mutually.
This structure is particularly advantageous; Because the rotation ratchet is positioned on the sliding part with the triggering member; So trigger the member translational motion; And control them subsequently more easily in stage of reseting and the relevant position of triggering the stage, relate in a word and let them turn back to their positions relative to each other to reset allowing.In fact, when its retainer returned, rotation ratchet and the interlock that triggers between the member must can be rebulid potentially during sliding part is triggering, and the existence of said interlock makes subsequently can reconfigure lock.This interlock in terminal allows to return device lock is turned back to the position that it is triggered, the motion of various parts it is reconfigured and no matter the position of sliding part how.
According to a feasible structure; The profile that triggers member and rotation ratchet comprises the second surface part of the motion that is parallel to sliding part; Permission is supported along second of the direction of motion of button when trigger finishing; So that it is mutually positioning when said triggering finishes, to make that surface portion strides across again, returns device and be positioned between ratchet and the sliding part with along the second direction bias voltage ratchet that support.
Depend on that sliding part does not particularly turn back to the situation of retainer, first surface makes that partly ratchet/triggering member interlock is stronger, allows simultaneously to support and more or less separates, thereby still can reconfigure, and this will describe hereinafter in more detail.The existence of second surface part guarantee these first surfaces parts correctly in the face of mutually positioning and no matter its distance how.
More specifically; The linkage structure that rotatablely moves that converts the translational motion of sliding part to platen comprises the outstanding contact site in surface from platen reversiblely; Said first contact site is housed in the oblong opening that triggers member and is guided therein; The orientation of said oblong opening be arranged essentially parallel to button by the motion under the ratchet holding state; Make to trigger member during first contact site rotatablely moving in the oblong opening reseted and move, so that realize the pressure support of first surface part and said first surface part is separated from each other when the motion that causes through triggering finishes towards ratchet.
According to the present invention, the axis of first contact site of intermediate disc is positioned on the line that is arranged essentially parallel to the button motion direction with the pivot axis that triggers member when sliding part is in adjacency state when triggering end.Allow the surface portion of first support in fact to contact subsequently so that allow to establish strict ratchet/triggering member interlock.When setting up interlock, exist very little or almost all do not rotate.On the other hand, when triggering, rotate along two rightabouts (seeing below).When sliding part did not turn back to its retainer, the rotation platen turned back to the oblong opening that its retainer make to trigger member and has the orientation of inclination under the influence of returning device of button, and made that therefore can produce the first said apparent motion that support leaves.
The linkage structure that rotatablely moves that converts the translation of button to platen comprises second contact site of giving prominence to from the apparent surface of platen reversiblely; Said second contact site is housed in oblong opening button, parallel with the motion of sliding part on the one hand and passes the semicircle slit of the wall that is fixed to housing on the other hand, and the end of said slit is configured for the retainer of the motion of button.Because dual boot, the translational motion of button is changed into rotatablely moving of above-mentioned intermediate disc.This rotatablely moving is endowed above-mentioned first contact site, and is delivered to the triggering member, and the oblong opening that when ratchet/triggering member links that rigidity has been set up, triggers member is held on the axis of movement that is in button basically.
In order to ensure operation; Last reseting in the position when the pivot of intermediate disc finishes; The moment of torsion that device applies on intermediate disc that returns through sliding part/ratchet/triggering component assembly and button relative to each other applies in opposite direction respectively, and the moment of torsion that produces through sliding part is greater than the moment of torsion that device produces that returns through button.When the interlock rigidity of ratchet/triggering member is set up, promptly when lock reconfigures, such situation that yes.
The position of sliding part is stable, and an end of ratchet is located in the core the adjusted below of electromagnet subsequently.
According to the present invention, be set in winding, not have attract to adjust core under the situation of electric current with the permanent magnet that can adjust core cooperation, be used to let core be set to let said core turn back to it to reset the position towards the device that returns that permanent magnet returns.
Preferably; These return device and comprise the torsionspring with spirality middle body; Said spirality middle body is orientated as and is centered around the axle journal that is fixed to housing; And radially stretch out two end branches from this spirality middle body, in the said branch one be placed in the housing of sliding part and another expansion in the said branch so that the track of interception movable cores.
These return device and only when triggering, are activated, so that can reset the position that can adjust core.When device was reconfigured, device was kept by permanent magnet, and the said device that returns no longer works.
According to a kind of possibility, sliding part is a spiral compression spring with the device that returns of reseting button.
Preferably; Locking mechanism according to the present invention comprises cross-shaped part; Said cross-shaped part is set to have midfeather and base portion; Said sliding part moves on said base portion, is directed translation in the pipe of button in being formed at midfeather, in the end of the first side button of midfeather from said pipe towards base portion outstanding; Said midfeather comprises the oblong opening; The guiding of said oblong opening is from the outstanding contact site of rotation platen, and said rotation platen uses the pivot in the opening that is housed in said wall and installed pivotly by the opposition side of abutment walls, and another contact site of giving prominence to from the apparent surface of said platen is inserted into the oblong opening that triggers member; Said contact site passes the oblong opening and advances towards base portion during reseting; The pivot axis of said triggering member is located near the end extended line of the oblong opening the base portion, and profile makes and can guarantee that first and second support the vicinity of the opposed end that is positioned at said oblong opening, and the return spring of sliding part is incorporated near in the housing of base portion and be applied to the effect of using between the base portion and second contact site.
This structure can constitute mechanical caging device of the present invention especially, and its form is compact and independently mechanical sub-component, is positioned in the housing of each difference block.Cross-shaped part is actually guarantees the support portion of described all position component at present, for example comprise can adjust core return device, axle journal, the spiral middle body of torsionspring be around said axle journal from a position of midfeather outstanding protuberance.Two plastic half-shells only guarantee that unit construction remains on the cross-shaped part.
Sliding part (in fact it be directed translation through the base portion of cross-shaped part) can be included in the side extending projection that is guided in the inner chamber of midfeather formation subsequently, and its control is to the switch of the condition signaling of lock.Sliding part uses second projection (28) and at least one switch cooperation, makes and can control electronic cards.

Embodiment
With reference to accompanying drawing; Specifically be that Fig. 1 a is to 1g; Support comprises cross-shaped part (crosspiece) 1 according to the module (block) of locking mechanism of the present invention; Said cross-shaped part comprises midfeather 2 and base portion 3 again, the path translation that sliding part 4 limits through retainer 5 in the base portion upper edge in one direction.Reset and receive guiding ground translation in the pipe 8 of button 7 in the midfeather that is formed at cross-shaped part 12.This button 7 can be resisted compression spring 30 the returning device of formation and actuated downwards.The rotatable intermediate disc 9 of the driven in translation of button 7, said platen is provided with projection 10 (see figure 2)s, and said projection freely is positioned at the oblong opening 11 that is arranged in the lower end of reseting button 7.Simultaneously, projection 10 is along moving in the semi arch part of the circular open 12 in the surface that is formed on pipe 8.
This triggering member 14 is included in nose 15 of its upper end, said nose the dual support for the teeth groove 31 of the ratchet 16 rotatably installed through the pivot 17 on the sliding part 4.
Should note triggering member 14 also rotatably installs through the pivot 18 on the said sliding part 4.Return spring 6 is bias voltage ratchet 16 along clockwise direction.Equally, return device 19 sliding part 4 is contacted (see figure 3) to pushing back with retainer 5.
In the midfeather of cross-shaped part 1, actuator 20 is orientated as with to reset button 7 parallel.In fact this is a kind of electromagnet, and its winding 21 be around adjusting core 22, and (at it when being not equal to zero) moves downward in the time of can adjusting core and in the conductor current of wanting protected circuit, unbalanced situation is arranged.This motion opposing again the spring 23 of (rearm) configuration a 23a of branch and take place, and the 23b of its another branch is connected to sliding part 4.In shielded circuit, have no under the situation of defective, the permanent magnet (not shown) makes it to remain on its rest position with adjusting core 22.
Sliding part 4 supports universal driving shaft (linking shaft) 24, and said universal driving shaft directly or through the connecting rod transmission system was set to trigger circuit-breaker lock side by side when the difference defective was arranged on the line.It is therefore outstanding from the housing of difference trigger equipment, so that cooperate with circuit-breaker side by side.
It should be noted that as previously mentioned the translation of sliding part 4 allows actuating of several micro switch, for example supply power to electronic cards, and the state (having disposed or not configuration) of checking lock.Thus, specifically, projection 28' is set to drive in the stage of reseting the switching that reflects sliding part 4 positions of little contact site 27.Equally, from sliding part 4 outstanding and window 29 movable projection (lug) 28 make and can actuate a switch that said switch sends the signal that shows the lock state and sees Fig. 2.
Operation of the present invention is following: reseting on the button 7 the user that antagonistic spring 30 is exerted pressure so that when reconfiguring product, the projection 10 that rotation platen 9 is positioned in the oblong opening 11 drives (see figure 2)s.Platen 9 is pivotably connected to the midfeather 2 of cross-shaped part 1, and above-mentioned specific contact site 10/ oblong opening, 11 STATEMENT OF FEDERALLY SPONSORED and allow translational motion to the transformation that rotatablely moves.Because this guiding; On the opposite side of midfeather 2; The contact site 13 that is fixed to platen 9 (said platen is housed among the oblong opening 14') will trigger member 14 at it when oblong opening 14' advances bias voltage triggers member 14 towards the right side of figure, shown in Fig. 1 b, and therefore drives whole sliding part 4; Because through nose 15 in the teeth groove 31 that is applied to said ratchet 16, trigger 14 is carried on the rotation ratchet 16.Antagonistic spring 19 applies the translation of sliding part 4 in this case.
After reseting, therefore lock is in the stable state through configuration of Fig. 1 b, because the existence of spring 19, sliding part 4/ rotation ratchet 16/ triggers member 14 assemblies and on the contact site 13 of rotation platen 9, applies power.Leaning in the upper/lower positions (being issued to this position at this state) of said contact site 13, this power produces moment of torsion, and said moment of torsion applies along counter clockwise direction to platen 9, because it applies below the pivot axis of said platen.And then; Reset button 7 use toggle position it return device 30 (promptly with respect to figure on the top in) on rotation platen 9, apply power; Produce the moment of torsion that applies in opposite direction, along clockwise direction promptly, because it is applied to the left side of the said pivot axis of platen 9.
Trigger moment of torsion that member 14 assemblies produce greater than reseting the moment of torsion that button 7 produces through sliding part 4/ ratchet 16/; Rotation platen 9 is maintained at by upper/lower positions; Be the bottom part that contact site 13 is positioned at the oblong opening 14' of trigger member 14, shown in Fig. 1 b.
In this static position; Being applied to the power that triggers on the member 14 trends towards letting it along rotation counterclockwise; And the power that is applied on the rotation ratchet 16 (particularly being applied to its spring 6) trends towards making it to be rotated in a clockwise direction; Dual support is applied on nose 15/ teeth groove 31 linkage structures of having set up, promptly one be supported on the surface parallel with the path of button 7 and one be supported on the surface parallel with base portion 3, prevent its rotation and guarantee the locking of described lock thus.
It should be noted that this position at sliding part 4, the spring 23 that reconfigures no longer applies any effect can adjusting on the core 22, saidly adjusts that core is attracted by permanent magnet and it is very high and any contact can not be arranged with the end of the 23a of branch.This effect neither be necessary, because remain on configuration (height) position because the existence of permanent magnet can be adjusted core 22.
Under the situation that the difference defective is arranged, actuator 20 is descended towards sliding part 4 thereby can adjust core 22 by electronic cards control.The spring 23 that this motion opposing reconfigures is realized, at least in its ending phase, shown in Fig. 1 c.
Can adjust core 22 and overlap, make its antagonistic spring 6 be rotated counterclockwise with an end (left part of Fig. 1 c) of rotation ratchet 16.The double bracing STATEMENT OF FEDERALLY SPONSORED is present at nose 15 place, triggers member 14 and is removed, and the balance that power forms is changed, because mechanical linkage is disconnected.The spring 19 of sliding part 4 subsequently with said sliding part 4 towards the right side of Fig. 1 c bias voltage.
Owing on the one hand release energy and be in the action of returning device 30 of reseting button 7 on the other hand, be applied to relative direction so be used for converting translational motion into rotatablely move mechanism from spring 19.Basically; Because rotation platen 9 is being reseted influence that button 7 rises pivot (said rising is (the seeing Fig. 1 f) that the effect of returning device of said button 7 causes) down and along clockwise direction; Owing to be placed among the opening 14' with respect to the return force contact site 13 that applies by spring 19; Said contact site 13 moves under the motion effect of member 14 subsequently and leaves the bottom of opening 14'; With continued its towards the sliding of the other end of opening 14', so trigger member 14 at first along counterclockwise pivoting around pivot 18.
In fact, when contact site 13 reached certain height, it was triggering action on the member 14 by conversely, and makes the latter pivot clockwise.If sliding part 4 reaches retainer 5; Then member 14 is with itself placing the position shown in Fig. 1 g; Vertical oblong slit, trigger risen said ratchet 16 slightly when member 14 turns clockwise after, nose 15 once more through the teeth groove 31 of rotation ratchet 16.At ratchet by its return spring 6 (this spring by in its branch on the sliding part 4 support) when actuating; Ratchet 16 is biased turning clockwise, so that when nose 15 teeth groove that has moved through ratchet 16, between nose 15 and ratchet 16, rebulid the dual support interlock.
Do not arrive at sliding part 4 under the situation of retainer 5; Contact site 13 is given prominence to from middle platen 9; Its rotation terminal point under the influence of returning device of button 7; And axis 18 no longer with the alignment of orientation that is arranged essentially parallel to said button 7 direct of travels, but follow well azimuth: the teeth groove of ratchet 16 is left in nose 15 motion subsequently, guarantees can reconfigure in all cases.As shown in Figure 4.A functional stabilization that benefit is its generation of this structure.
The other end at sliding part 4; Because the motion that sliding part 4 (sees that Fig. 1 e is to 1g) to the right; The spring that reconfigures 23 is through the 23b of branch and by the housing extruding, thereby and its pivot contact 23a of its branch that can adjust core 22 make said core upwards towards the permanent magnet motion that is set to hold it in rest position.And then universal driving shaft 24 is fixed to sliding part, and said sliding part is by the right side translation towards figure, and it applies direct or indirect effect on the lock of the relevant circuit-breaker that is triggered.Arm 25 turns back to its original position, and reuses spring 26 and make contact site 27 open and close.
