According to the structure of protection system 1; obviously; the mechanical force and the stress that act on drive link 70 are far from it; but need maintain enough accuracy to the position of drive link 70, order (power and moment of torsion) and information (speed, stroke, gap etc.) to guarantee the reliability of system 1 without change.Particularly, drive link 70 can not cause any dysfunction because of its functional insertion between auxiliary member 12 and circuit breaker 2.Thereby, according to the present invention, in the time that power is applied to the second end 72 of drive link 70, drive link 70 maintains and is less than 0.15mm in the transversely deforming of first end 71, preferably be less than 0.1mm, and described power usually thinks and equals every utmost point 3N, and in the time that the second end 72 is subject to the vibration at end of travel place, particularly run in the situation of the engagement being made up of front panel 26 during in closure or open position at handle 50, described vibration can have the semisinusoidal intensity of the regularization of about 15g/11ms.

According to the present invention, the drive link 70 of remote control unit 20 by the material of aluminium or magnesium alloy type or preferably by the Zamak of humidity and/or temperature-insensitive is made, for example, is made by the injection molding of metal.The length of drive link 70 between its two ends 71,72 is by unit L ₂₀size determine, i.e. preferably approximately 60mm or 80mm, the thickness of drive link 70 is chosen to make bar 70 can or can not be out of shape hardly under the effect of actuating force and resistance.Particularly, large body thickness is about 0.7mm, and has reinforcement at critical component place, particularly in end piece 73,74 with at the At The Height of pivot pin 77.Roundabout owing to not having, thus realize the information between switch element 2 and auxiliary member 12 and/or ordered the optimization transmission via remote control unit 20, or even in the harshest climatic environment.

According to preferred embodiment, particularly magnet of magnetic devices 80 made and is equipped with by bar 70 by nonmagnetic substance, thereby can provide the information about the position of bar 70 and the position feature of switch element 2.For this reason, as shown in Figure 5A, at least one transducer 82, preferably hall effect sensor, even MEMS or other transducer also can, be assembled into towards magnet 80, so as in direct-detection remote control unit 20 about the information of the angle position of drive link 70.The signal being detected by transducer 82 is passed to printed circuit board (PCB) 23 for analysis, to provide ON/OFF signal.Therefore, with the information that the trip(ping) bar 7 of approach switch unit 2 is obtained as far as possible, more reliably and to common auxiliary member module 12 _ithe information of the less sensitivity of magnetic dispersion (dispersion) that distance of living in causes, can directly be supplied with via one of connection 25 arranging by electronic commutator without attachment device.According to preferred embodiment, magnet 80 is embedded into, and is particularly embedded in forcibly in the suitable layout 78 of drive link 70, and described magnet 80 is made up of neodymium/iron/boron alloy and is the cylinder for example with 5mm diameter.

Magnet 80 preferred fit become to make its edge-perpendicular in transducer 82,, as shown in Figure 5A, hall effect sensor 82 is roughly orthogonal to the axis at the two poles of the earth of the magnet moving along magnetic field line B, strengthen thus the identification power detecting, therefore in the stroke α of hall effect sensor 82, the difference of deviation less (being less than 1.5mm) between the position of drive link 70.In the time that magnet movement exceeds the surperficial INTRM intermediate point of hall effect sensor 82, transfer between magnetic field line B is thoroughly, and transducer 82 can detect magnet 80 and whether be positioned at its right or the left side, and a large amount of electrical interaction of pipe shell 21 inside not.By means of this optional way, thereby transducer 82 can be arranged to approach magnet 80, and is less than 2mm from drive link 70 particularly, and does not affect mensuration resolution.

Position transducer 84 also can be assemblied in the At The Height of the base portion 53 of handle 50, to detect the position (also seeing Fig. 1) of handle.This association thereby can give the information of signal/fault type, thus have advantages of as hereinbefore.The measurement in the time interval between the switching of the switching of drive link 70 and handle 50, the tripping operation in fact can distinguish electric fault time and hand trip(ping).People's interference makes handle 5,50 about 20 μ s setting in motions before trip(ping) bar 7 rotates, and therefore drive link 70, in view of hot type, magnetic-type or differential type tripping operation, makes bar 70,7 about 4ms of motion before handle 5,50 motions.

According to the advantageous embodiment shown in Fig. 5 B, two transducer 84A, 84B are arranged to have the angular deflection β ' of the motion β that is less than handle 50 particularly, for example symmetrical so that measure the detection of more reliable, to make handle 50 extreme position and the open position of contact 4 and the detection of make position and carry out in reliable mode to separated time about the movement angle β of handle 50.This optional way also may be used on the magnetic devices 80,82 of trip(ping) bar 70, although its motion is less.Using multiple transducer 82,84, particularly in the situation of three or more transducers, in order to make power consumption minimum, first sensor 82, particularly relate to a transducer of the make position of drive link 70, can supply with the electric current of pulse or non-pulse, and to the only just power supply in the time that microprocessor detects the variation of state of first sensor 82 of other transducer.

In a preferred embodiment, as the trip(ping) bar 7 of switch element 2, the drive link 70 of remote control unit 20 rotates around pivot pin 77, to occupy the disconnection of contact 3 or two remarkable positions of closure state of circuit breaker 2, crosses over the angular travel α of about 20 degree.In order to limit the power being applied on drive link 70, drive link 70 is carried out to balance, the center of gravity of drive link 70 is roughly positioned on its pivot center 77.Therefore the impact of the mechanism of the mechanism of drive link 70 on auxiliary member 12 and circuit breaker 2 is zero, and additional mechanical stress is minimum, and described additional mechanical stress may be posted the information transmission investing between auxiliary member 12 or switch element 2.According to preferred embodiment, preferably in overall mode, bar 70 be furnished with to shift center of gravity, fly piece 79 towards an end 74 of bar 70.Whether this structure can be adjusted according to the existence of size, free space and magnetic devices 80, to be magnetic devices 80 vacating spaces 78 in keeping center of gravity near pivot pin 77.

For reasons of safety, indispensable, while carrying out the assembling of remote control unit 20, switch element 2 is in off-state, i.e. the aligned position of drive link 70, and this realizes by means of the preset spring of assembling conventionally.According to an advantageous embodiment of the present invention, in order to limit the power that drive link 70 moves that hinders, drive link 70 be mounted to lazy formula, do not have spring and bar 70 to realize by means of locking accessory 60 in the biasing of its rigging position, described locking accessory 60 offer remote control unit 20 so that it operation end.Particularly, be assemblied in bias operation bar on the pivot pin 77 of drive link 70 as calibration device.It cooperates with the attachment component 65 of locking accessory 60, is driven the formula motion that rotates.

Therefore remote control unit 20 provides locking accessory 60 for example in outstanding (protruding) position.Once remote control unit 20 engages with switch element 2 and auxiliary member module 12, locking accessory 60 can be depressed, make attachment component 65 discharge the bias operation bar of drive link 70, then this bias operation bar and switch element 2 and auxiliary member module mechanical connection, thus the information that can realize is from circuit breaker 2 to auxiliary member 12 and reverse bi-directional.

Parallel with the information transmission of optimizing, remote control unit 20 according to the present invention also has the reaction time of optimization, particularly has high actuation speed, thereby can make handle 50 with 1200 ° of s ^-1speed motion.Particularly, between trip signal and the effective action of contact 4 closures, through being less than half second and time of 300ms preferably approximately.Therefore the handle 50 of remote control unit 20 moves by means of electromagnetic actuators 100, instead of by means of the electric rotary machine motion with about closing time of 1 to 1.2s, described electromagnetic actuators 100 is that a kind of very fast, acceleration can be by means of the stepping actuator of modulating of powering.

(also see Fig. 3) substantially as shown in Figure 6, comprise according to the actuator 100 of remote control unit 20 of the present invention: the coil 102 being wound around on the sheath 104 around axis AA; Be fixed to the housing 110 of the shell 21 of remote control unit 20; With the magnetic piston core 120 that can move according to the axis AA of electric current Figure 102 along the line mobile in coil 102.The motion of core 120 is subject to pulse signal control.In the time stopping, in coil 102, there is no current flowing, and air-gap e between the bottom 111 of housing 110 and the base portion 121 of core 120 is in maximum, and core 120 is at the outstanding housing 110 that leaves of Outboard Sections 122.Signal causes current flowing in coil 102, and at least a portion of the Outboard Sections 122 of core 120 moves to housing 110 inside.The Outboard Sections 122 that is still retained in the core 120 of housing 110 outsides is provided with the fixture 123 of the driving mechanism 150 for being fixed to handle 50, particularly, described fixture 123 is a kind of breech locks 123, this breech lock 123 is designed to rotary type action bars to be indirectly biased to the base portion 53 of handle 50, rotatablely moves to the linear movement of movable core 120 is transformed into part.But term " pulse " should be by the broad understanding of word: as further shown, control law advantageous applications, to actuator 100, to optimize the operation of remote control unit 20, particularly reduces the wearing and tearing of contact 4.

According to the present invention, the electromagnetic actuators 100 of remote control unit 20 can be used for high power, and must four single-pole circuit breakers 2 of instruction _iwhole auxiliary members 12 as shown in Figure 1 _i, or the closed and disconnected of four utmost point differential switchs of 125A.Therefore, the actuating force of required generation is large, and with regard to preferred embodiment, can reach 100daN and stroke 5mm.But the volume of distributing to actuator 100 keeps limited (about 40 × 35 × 50mm) with regard to horizontal and depth direction space.According to the present invention, therefore a kind of electromagnet 100 with rectangular core 120 of choice for use so that utilize substantially can magnetization surface.Housing 110 also has general rectangular formula parallelepiped shape, in addition, the axis AA of actuator 100 with respect to the panel deflection of shell 21 to utilize available space, for example, with respect to the angle γ of 4 ° of vertical directions.

In addition, consider suffered strong jarring under each attraction, selected the core 120 made by agglomerated material, make performance can not weaken in time and optimize durability.Such material provides other advantage, and the fact is that such material can produce the fixture 123 for fixed core 120 with integral way in the time carrying out sintering operation.Further advantageously, the edge 124 of core 120 has carried out passivation to prevent any infringement, and according to preferred embodiment, the edge 124 of the AA that parallels to the axis has matrix.

The stress absorbing due to electromagnetic actuators 100 is large, and housing 110 also plays a part fixed coil 102.Housing 110 comprises particularly: be parallel to bottom 111 and be roughly orthogonal to the second end wall 112 of the axis of movement AA of core 120, the second end wall 112 arranges porose 113, the size in this hole 113 can allow core 110 pass but be less than the occupied area of coil 102, and coil 102 is blocked between the diapire 111 and described wall 112 of housing.Advantageously, the outward flange of the second end wall 112 of housing 110 114 is cut, thus the amount of limiting material and be the passage vacating space (seeing Fig. 3) of the driving mechanism 150 of handle 50.The assembling of the different parts of actuator 100, with self shape of housing 110 be more complicated, according to the present invention, housing 110 is preferably formed by two symmetrical parts 110A, 110B, and described two symmetrical parts 110A, 110B are made up of agglomerated material and the hard spot (hard-point) on the extension 106 of the plasticity sleeve 104 of coil 102 and being fixed to each other by means of the At The Height pinching at diapire 111.Except the simplification of manufacturing, it is cheap that this solution is proved to be, and the work that has prevented the housing of being made up of the sheet metal that the folding caused performance of hardening is cut down.

In order to optimize the fixing of coil 102, the sheath 104 that coil 102 is installed place also stops coil 102 on the face of the axis AA perpendicular to coil 102.Sheath 104 also longitudinally 108 extends to be assemblied in access opening 113 at the At The Height of the second wall 112 of housing 110.Fixing between two part 110A, 110B of housing, this optional way has been guaranteed minimal distance of separation between housing 110 and core 120 Optimum Operation for actuator.Advantageously, sheath 104 is made by having certain thickness rigid thermoplastic material, and this thickness is just in time enough to core 120 to separate with housing 110 so that core 120 can slide, and simultaneously sheath 104 has maximum magnetic flux and for making the maximum power of core setting in motion.

By chance, above technical selection causes the performance relevant with institute's generation power with speed of core 120 to go wrong, and the fatigue of the diapire 111 of for example housing 110, may arrive the degree of breaking.At end of travel, the air gap distance e between housing 110 and core 120 levels off to zero, and this causes the acceleration of core 120, and this acceleration can cause fierce jarring.According to the preferred embodiment of the present invention, except the adjustment of control law, vibration absorber 115 is assemblied on the diapire 111 of housing 110 towards core 120, and described vibration absorber 115 is for example made up of nitrile (nitrile).Except shown in other optional way also passable, particularly, assembling vibration absorber forms the wall of housing, and can be by means of driving core at end of travel and with respect to all the other housings motions.Can conceive in the various replacement schemes shown in French patent application number FR 0807163.

In addition, the base portion 121 of core 120 self is hollow, to air is added in magnetic flux circuit, reduces thus the magnetic force at end of travel.Advantageously, lateral recess 125 is hollow in core 120, to maintain direct core 120/ housing 110 engagements of end of travel, thereby restriction is applied to the power on vibration absorber 115, this vibration absorber 115 is contained in recess 125 completely, in final compression position, so as can exceed 40000 times operation in bring into play function.Recess 125 is preferably made the direction that is orthogonal to breech lock 123, and this makes to utilize the manufacture process of agglomerated material and single axial pressure easier.Particularly, recess 125 is essentially rectangular, has surperficial S ₁₂₅and degree of depth h ₁₂₅, the degree of depth of described recess is no more than the still length h in housing 110 of core 120 along the axis AA of core 120 ₁₂₀-h ₁₀₈-h ₁₂₂.

Consider the surperficial S of core 120 ₁₂₀, therefore, the maximum power F of actuator 100 _maxmodulated in the motion process of core 120, thus the acceleration of core 120 reduced.In this way, in the time there is no recess 125, in the time that air-gap e goes to zero, the theoretical velocity of core 120 is tending towards infinitely great, but recess 125 is by means of producing S ₁₂₅× h ₁₂₅the air-gap of volume and make this action slow down.Deceleration parameter Δ F can be calculated by formula:

$\left(1\right),\mathrm{\ΔF}=\frac{\frac{S_{125}}{e^2}-\frac{S_{125}}{{(e+h_{125})}^2}}{\frac{S_{120}}{e^2}}$

It may be noted that thus as the volume S than air-gap ₁₂₀× e, due to the little value S of the air volume increasing ₁₂₅× h ₁₂₅, when air-gap e is large, be insignificant on the impact of actuation force F.Therefore actuator 100 applied forces motion initial time can not be cut down.On the other hand, in the time that air-gap goes to zero, described volume is about no longer ignoring each other, and in the time activating end, described power may reduce about 15% to 20%.Described recess 125 can have another shape except above-mentioned, this solution of recess 125 provides the two-fold advantage that increases air-gap e and produce saturation effect in the periphery of core 120, the speed slowing down thus in the time activating end, particularly after the resistance of the switching mechanism 3 of circuit breaker 2 has started to decline (Fig. 2), particularly, in a preferred embodiment for the total kilometres of about 12 millimeters in the time that air-gap e is less than or equal to 1mm, this determines preferred air volume.In fact advantageously,, in the time expecting speed-down action, the volume of recess 125 is roughly corresponding to air-gap e × S ₁₂₀volume.

More accurately, if expected from being less than threshold value e corresponding to air-gap e _s(for example e _s=1mm) moment the predetermined stroke of core 120 is slowed down, the additional volume of the air being provided by recess 125 must become significantly, i.e. S ₁₂₅× h ₁₂₅>=1/2 e _s× S ₁₂₀, and e preferably approximately _s× S ₁₂₀such volume.More generally, the volume that recess 125 has is more than or equal to the half at the volume of the half trip of core 120 or the air-gap e of four/triple-travel place.The volume of recess 125 is preferably greater than or equal to 3/4ths or the volume of five/four-stroke place air-gap.

The height h of recess 125 ₁₂₅and relation between the width surperficial S with regard to itself depending on that vibration absorber 115 is required ₁₂₅with manufacture simple and easy.Especially, importantly there is enough metal qualities and suitable solidity for core 120.Regardless of the position (also comprising in initial position) of housing 110 SMIS 120, recess 125 does not pass core 120 along axis AA.Advantageously, the degree of depth h of recess ₁₂₅be less than the length h of core ₁₂₀-h ₁₂₂half, and preferably the cross section of the AA that parallels to the axis of recess 125 is general square shape or the rectangle that the ratio of the length of side is less than 1: 2.

Particularly, according to the present invention, the core 120 of being made up of 0.45% iron/phosphorus moves through e=11mm to 12mm (11.7mm) and section S ₁₂₀for 270mm ²to 300mm ², described cross section is approximately 280mm particularly ²(20.6 × 13.6).The housing of 4.8mm thickness can be made up of the steel with identical sintering property.Coil preferably includes the 640 circle coilings of pitch 2 × 18mm, diameter 355 μ m.In the time that electromagnet 120 remains the stroke of 1mm, roughly its amount of movement 4/5 after, the effect of recess 125 is desired especially, so the size of recess 125 is 2 × 123.6mm ², or 1.5 < h more generally ₁₂₅< 3mm, 62mm ²< S ₁₂₅< S ₁₂₀, and vibration absorber 115 has the height of 4mm.

In addition; in the time that protection device and auxiliary member have passed through their energy point of release; the Outboard Sections 122 of core 120, be arranged in standing finish 123 belows to this mechanism and at housing 110 in active position, also attenuation is to reduce the performance of actuator 120 at movement travel end.Particularly, form double inclined plane 126.

Electromagnetic actuators 100 is for making handle 50 turn to open position from make position.For this reason, property illustrates with shown in Fig. 7 as schematically shown in Figure 6, and the base portion 53 of handle 50 is connected to the arm in the fixture 123 that is hinged on piston core 120 by means of driving mechanism 150.Particularly, the breech lock 123 with about 12 millimeters of strokes joins the first arm 151 or action bars to, and it is rotated around the pivot 152 of the shell 21 that is fixed firmly to unit 20.The pivot 152 of action bars 151 is preferably placed at one end, and the fixing point 153 that is fixed to breech lock 123 is roughly positioned at the first Bei151 center.Particularly, sketched the contours of by pivot 152 two sections, fixing point 153 is greater than 4/5 with the residing ratio of the other end 154.In a preferred embodiment, action bars 151 is made and is comprised by the sheet metal of folding cutting: the hole of passing through for the sintered type breech lock 123 of core 120, and for example embed by pressure the bar 153 for fixation kit being fixed.Action bars 151 joins bar 160 at its free end 154, although bar 160 has angular deflection with the axis of movement AA of core 120, bar 160 is roughly parallel to the axis of movement AA motion of core 120.Preferably approximately 16.6mm of the stroke of bar 160.In order to realize adjusting (also seeing below literary composition), bar 160 is bonded in one section of limited distance relative to freely rotating, for example, by means of a segment distance of engagement restriction.Here again, fixing by means of advantageously realizing with engaging of steel pole 155.

Because electromagnetism 100 is unidirectional pulse actuators, at position of rest (seeing Fig. 7 A), when electric current does not flow in coil 102 and core 120 in " on " when position, handle 50 remains on the position being driven and arrive.Handle 50 connects preferably separablely between the driving mechanism 150 of two arms with having, and bar 160 only engages for the motion process at electromagnet 100 and in the stroke at it, handle 50 activated.Particularly, bar 160 cooperates with the layout 55 of the base portion 53 of handle 50 via an end pieces 161.Because handle 50 is provided with the base portion 53 (seeing Fig. 4) that is two parts of skew along pivot center 52, the end pieces 161 of drive rod 160 is preferably the form of cross bar (cross-piece), described in arrange and be rendered as the form of the guiding groove 55 on the annex 56 that is integrated into base portion 53 and roughly at axis 52 middle parts.In the time that actuator 100 is got back to its initial position of rest, therefore handle 50 keeps putting in place.Action bars 151 is preferably provided with the device that it is biased to its initial position, and for example, at its torsionspring 156 of At The Height of pivot center 152, so that the driving mechanism 150 of handle 50 is monostable, handle 50 just itself has two stable positions.

Be assemblied on switch element 2 for resetting and working as remote control unit 20, the position of handle 50 is corresponding to the open position of contact 4, and core 120 is outstanding from housing 110.According to the present invention, this replacement position is the initial position of the second end 161 that can contact lever, and is not pressed on the groove 55 of handle, sees Fig. 7 A.Advancing by leaps and bounds of described pulse signal genration core 120 followed the corresponding sports of the free-ended cross bar 161 of bar 160 simultaneously, and the advancing by leaps and bounds of described core 120 applies pressure to the groove 55 of handle 50 so that handle 50 turns to the make position of contact 4, sees Fig. 7 C.Advantageously, driving end, handle 50 runs into the engagement being formed by shell 21 to ensure the closure of contact 4.But for the power that reduces to provide, the end of travel of core 120 is also corresponding to the engagement position between core 120 and housing 110, i.e. zero air-gap e.A kind of so hyperstatic situation implements very complicated, and can become in time on earth very unreliable, and makes electromagnetic actuators 100 move very fast and their joint of opposing engagement is therefore very fierce.

In order to alleviate this problem, there is different optional ways.Provable, do not considering particularly differential auxiliary member 12 of other auxiliary member 12 ₁control easily under influenced this fact of case, in circuit breaker 2 through stop the driving of handle 5 after the stop of handle 5 by the stroke slowing down and/or limit core 120, this is very insecure after the operation of number of times necessarily.Stop that handle 50 produces stress and power in a position, place that compresses shell 21, this situation has the tendency of the operation of infringement actuator 100.According to the present invention, actuating mechanism 100,150 is formed device 162 and eliminates via the spring that can absorb dynamic and/or static stress by the driving mechanism 150 of handle 50 in the indeterminate position of the closing stroke end of contact.Device 162 is preferably located on the second arm 160 of driving mechanism 150, and described the second arm 160 comprises relative to each other movable two part 160A, 160B.Its length reduces in case there is stress, and for example, from 1.5 to 2mm, but bar 160 is biased to extended position by the device 162 of types of springs, until threshold value.

Particularly, if be less than the required power of driving handle 50 activating the rigidity of spring 162 while starting, spring 162 is setovered by means of the motion of core 120 and free end 161 and the handle 50 of bar 162 do not move (Fig. 7 B).Make its rigidity be greater than actuating force after a while in the biasing of spring 162, bar 160 just move and apply pressure to handle 50 so that handle 50 rotate around its pivot 52.At the end of travel place of core 120, be stored in energy in spring 162 and can be used to desirably the stroke of handle 50 be extended to its engagement position (Fig. 7 C).Or, if forming device 162, spring there is the rigidity larger than the actuating force of handle 50, bar 160 just directly starts driving handle 50 formula that rotates from the motion of core 120 and moves, and at the end of travel place of handle 50, spring forms device 162 and is designed to store until the energy that the end of travel of core 120 configures.

According to the structure of protection system 1, even if handle 50 moves and makes the power of contact 4 closures, actuating mechanism 150 is a kind of situation in above-mentioned situation or another kind of situation in fact, or even in the combination in two kinds of situations.And, because the stroke reducing relative to the earth between two part 160A, 160B of bar (approximately 1.5mm) and a small amount of free space, apply prestressing force so preferably spring is formed to device 162, to ensure in closing stroke end for the enough power of this little motion, thus produce Dual-contack and on the front panel 26 of housing 110 or shell 21 without any stress.

Described actuating force does not preferably directly act on spring from action bars 151 and forms device 162.The Part I 160A of bar comprises the chamber body 163 for telescopic Part II 160B, and telescopic Part II 160B is subject to chamber body 163 to guide translation, and can slide with respect to chamber body 163 in the two ends of telescopic Part II 160B.

In remote control unit 20 according to the present invention, therefore this solution of slip pole 160 means, the structure of the structure of circuit breaker 2 and remote control unit 20 is not subject to, due to the strain indeterminate any static state causing and dynamic, to have reduced considerably thus the wearing and tearing that the mechanism of remote control unit 20 and the mechanism of switch element 2 cause because of fatigue.Therefore the operating reliability of unit 20 can extend to 20000 operations of as many as.This optional way can also make whole kinematics stroke be used, and can realize thus the multiple structure of protection system 1 is activated, particularly hereinbefore described all that structure.

Advantageously, select spring to form the middle rigidity of one of device 162, this centre rigidity is included in protection system 1 (the single circuit breakers pole 2 of minimal construction _i) mesopodium is with the power of actuation handle 50 and in the protection system 1 of maximum structure between the required power of actuation handle 50.Particularly, recommend the prestressing force of about 50N.Consider the remote control unit shell 21 of small size, preferred bar 160 comprises at least two springs 162 ₁, 162 ₂.For assemble simple and easy with in order to optimize their size, in the preferred embodiment of the present invention, two identical springs are assemblied on parallel fork body 164.In order to optimize the direction of transmitted power, y-bend body 164 every end advantageously by they chamber body 163 the guiding of two holes and be bonded on one end, engage by means of the free-ended cross bar 161 of bar 160 particularly, described cross bar 161 is designed to cooperate with the arranging of the form that is groove of handle 50.

Advantageously, the rigidity Part I 160A of bar comprises two parallel chambers bodies 163 for each fork body/spring assembly, for example, be bonded on form Wall board At The Height, that be two rectangular parallelepiped protrusion part chambers.The outer side panel of the Part I 160A of bar preferably extends beyond bottom panel, and the supporting fork body 164 of spring 162 upwards exposes to supporting bar from bottom panel.Also can heavier-duty protection be set around the fork body of described slip.In the preferred embodiment illustrating, one of side panel 165 of the Part I of bar also extends beyond supporting bar 161, so that the assembly of protecting sheathing 21 inside.This structure makes assembling easily, has optimized available diameter and the length of spring 162 simultaneously, and the diameter of their distribution.But other replacement scheme is also possible, particularly relate to the shape of rigid element 160A and the shape of its each parts of bar.Rigid element in order to ensure bar is got back to initial position with respect to the first arm 151 of driving mechanism 150, further advantageously, assembles applicable device, for example torsionspring 166 in the position being fixed with action bars 151.

As previously mentioned, activating end, core 120 is returned to its initial position, handle 50 keeps putting in place, and driving mechanism 150 is got back to upper (up position), be no longer fixed to the base portion 53 of handle 50 at described upper place driving mechanism 150, see Fig. 7 D.In situation at remote control unit 20 as the running of replacement device, only carry out this sequence.Tripping operation is reset to handle 50 closure of the position of Fig. 7 A and the actuating of core 120 reproduction Fig. 7 C.Also realize in the situation of disconnection of circuit breaker 2 in Long-distance Control, the actuating of core 120 also needs to make handle 50 to rotate along other direction, applies traction or the opposite side applied thrust at the pivot pin 52 of handle 50 in the end of the base portion 53 of handle 50.Thereby, prove that additional device is necessary.

According to the present invention, assembling guidance system 170 can act on a side or the opposite side of its pivot pin 52 to guarantee bar 160, according to the position of handle 50, to carry out the closure of contact 4.Particularly, guide portion 171 is one of end cross bar 161 guide path of bar 160 or another, and bar 160 is with respect to this change of the relative freedom feasible direction of action bars 151, and described guide portion 171 is preferably etched on the side panel 10 of shell 21.For by one of bar 161 guide path 171A, 171B or another, rotary type V-shape portion part 172, as shown in the preferred embodiment of Fig. 9, is preferably integrated in the shell 21 of remote control unit 20.Particularly, parts 172, for example be made of plastics, rotate and follow the motion of handle 50 around pivot 173, the base portion 53 of handle 50 comprise parts 57 can with the first arm 174 associated working of V-shape portion part 172 in the close position, make the second arm 175 of V-shape portion part " close " close passage 171A (Fig. 7 D, 9B).In this way, activating end, the end of bar 161 is pressed on handle 50, thereby V-shape portion part 172 is rotated.In the time that bar 160 is got back to initial position, handle 50 and V-shape portion part 172 are held in place.In stroke end, relative flexible due to actuating mechanism 150 applied forces and the second arm 175, bar 160 can be by guidance system 170 tonings (overshoot).Once guide portion 171 toning, V-shape portion part 172 returns to its position, and the rigidity of the power of handle 50 and its first arm 175 is greater than the bias force that bar is joined to the spring 166 of action bars.Therefore bar 160 slightly turns to the second path of etched guide portion 171.

In the time that piston core 120 activated, as shown in Fig. 7 E, impel action bars 151 to rotate and bar 160 translations, but etched guide portion 171, by another parts of bar 160 caster assembly therefors 50, is positioned at the pressor areas 58 of the opposite side of its pivot 52 particularly on shell 21.Because the rectilinear motion of bar 160 and the combination of angular movement therefore can realize the motion transmission of a side of handle 50 or the electromagnetism 120 of opposite side in narrow passage.Pressor areas 58 can be similar in appearance to above-mentioned groove 55, but, because the required force rate replacement power little a lot (seeing Fig. 2) of the disconnection of contact 4, thus can be more strongly engaging lever 160 and handle 50.Particularly, the part 161 of bar 160 can be enough in the time that motion starts with surperficial the cooperating as cam 58 of the base portion 53 of handle, and after energy point of release and before the utmost point position of welding, driving handle and contact are to open position.In this tripping operation action, according to external form and required power, may need the spring formation device 162 of bar 160 to cause, but tripping operation is realized conventionally by direct rotation.

Once handle is in open position, V-shape portion part 172 just can rotate freely: Fig. 7 F (with Fig. 7 A).In one embodiment, V-shape portion part V172 is mounted to lazy formula.When bar 160 is in the time that end-of-pulsing is got back to position of rest, the bias force of driving mechanism 150 is enough to the unlatching (Fig. 9 A and Fig. 7 F) that drives the second arm 175 of V-shape portion part 172 to arrive closed path.But, preferably at the At The Height assembly prestress spring 176 of V-shape portion part 172, the power of repulsion bar 160 is calibrated in the guide portion 171A of "off".

It should be noted that when circuit breaker 2 is because fault trip disconnects, thereby outside trip unit 20 time, the non-confrontational any prevention of handle 50 being got back to the returning place force of open position of action bars 151 of remote control unit 20.Guidance system 170 is mounted to lazy formula, does not therefore stress, rubs or block at centre position handle 50.Therefore this solution is reliably, has small size, simple and comprise only a small amount of parts, and unlike the solution shown in document FR 2840449 or FR 2535520.

Actuating mechanism can be realized by means of simple parts the high speed twocouese driving of handle 50 thus according to the preferred embodiment of the invention, is not subject to stress at settling position.Also advantageously, optimize the control law of electromagnetic actuators 100, when approaching the closing of contact as much as possible and while disconnection in contact accessorily, the force curve figure of the handle 5 of circuit breaker 2 as shown in Figure 2, for example, impact to protect the latter by restriction is closed.

Particularly, according to the present invention, electromagnetic actuators 100 is connected to the control device of processing unit 23 by means of control device, to produce potential pulse in the coil 102 of supplied alternating electricity.Particularly, can adopt the rule described in number of patent application FR 0807155.

Particularly, as shown in figure 10, control device is designed to produce and comprises at least n rectified half-waves S _iperiodic voltage ripple frame (frame).As an example embodiment, the duration that periodic voltage ripple frame has is equal to or greater than 50ms.According to preferred embodiment, each half-wave S _icomprise at least the first and at least the second pulse excitation order S _a, S _b.

The first pulse excitation order S _aroughly start from the zero volt of half-wave S, and the second pulse excitation order S _broughly end at the zero volt of described half-wave S.The first half-wave S _ithe electric energy that produces of pulse excitation order less than or equal to described the first half-wave S _ithe second half-wave S subsequently _i+1the electric energy that produces of pulse excitation order.Last rectified half-waves S of the waveform frame being sent by control device _npreferably include and roughly start from the first pulse excitation order S _athe second pulse excitation order S of ending place _b.Advantageously, in order to ensure effective actuating in most cases, control device produces the periodic voltage ripple frame that comprises at least five continuous rectified half-waves.

According in Figure 10 with the alternate embodiment shown in reverse hacures, control device produces and comprises at least the three pulse excitation order S _cat least one rectified half-waves, this (these) the 3rd order S _cin described first and second pulse command S _a, S _bbetween time frame in.

Therefore optimized the dynamic closure to ensure switching device or dynamically disconnected by means of selected optional way according to remote control unit 20 of the present invention.Particularly, can start to obtain lower speed in actuating and be engaged with each other to guarantee parts, then accelerate to give power and energy, this can change according to structure, and finally in the time of motion end, slows down so that impact energy minimizes.This optimization obtains by means of control law, described control law produces a kind of progressive motion, being less than in the disconnection of 200ms or closed-loop path by means of the electromagnet 100 with mobile core 120, the power of described mobile core 120 is the rotation compatibility of enough and total stroke and handle 50 at air-gap e (maximum), and mechanism 150 can realize and to move and the transformation of power.Particularly, the preferred solution of difference according to the present invention has synergistic effect.
