Definitions
- the present invention relates to a control device of a electromagnet in a low voltage electrical switch device, of the type contactor, relay, circuit breaker or contactor-breaker, including excitation coil comprises an electrical supply circuit having an auxiliary contact.
- the invention also relates to a switch device comprising such a device.
- Switching devices have fixed contacts of poles which cooperate with mobile pole contacts in order to switch a load downstream electric. They also include a magnetic circuit comprising a frame mobile coupled to the movable contacts of poles and controlled by a coil excitation when it is traversed by an electric excitation current. The operation is generally carried out according to the following principle.
- a sufficient inrush current for the mobile armature of the magnetic circuit consisting of for example a movable pallet, or driven from a rest position to a position job.
- This displacement also causes the displacement of the moving contacts of poles of the device.
- the pallet is held in working position as long as a sufficient holding current crosses the coil.
- the excitation current disappears or decreases below a certain threshold and the moving pallet returns from the working position to the initial rest position for example by means of recall, such as a return spring, also generating the reverse movement of the moving contacts of poles of the device.
- the inrush current required by the coil to control moving the moving pallet from the rest position to the working position is more important than the holding current. This phenomenon is even more true with DC electromagnets. Consequently, if the current consumed by the coil remains the same during the call and hold phases, this will cause either unnecessary heating of the coil during the holding phase if it passes through Permanently by the inrush current, ie a bad movement of the moving pallet if the coil is traversed by the insufficient holding current for the call phase, with risk of sticking the pole contacts of the device.
- a first way is for example to design an electromagnet having a secondary additional excitation coil which is connected in series with the main coil only during the hold phase, or connected in parallel with the main coil only during the call phase.
- Another way is also to connect a resistor in series with the main excitation coil and to shunt it during the call phase using a auxiliary contact which is connected across the resistor and whose opening and closing are controlled by moving the movable pallet.
- a auxiliary contact which is connected across the resistor and whose opening and closing are controlled by moving the movable pallet.
- the moment of switching of the auxiliary contact is essential to the opening as the closing of the contact.
- the opening of the contact auxiliary is done too early during the movement bringing the movable pallet of the position rest towards the working position, the series setting of the resistance causes a decrease the electromagnetic force provided by the coil. This electromagnetic force risk of not being sufficient for the pallet to reach the working position of satisfactory way. This can lead to incorrect switching of the device light switch.
- WO0120632 shows a device comprising a magnet permanent that allows to perform a hysteresis between the movement of the pallet mobile and switching an auxiliary contact to connect or not to connect a resistance in the supply circuit of a coil in a switch device.
- This hysteresis makes it possible to shift the switching of the auxiliary contact at the moment desired.
- the magnetization effort of a permanent magnet varies with the temperature.
- this device can be placed next to heating elements of the electromagnet, there is a risk of non-reproducibility of precise moments opening and closing of the auxiliary contact according to the conditions of use of the device.
- a magnet is likely to attract metal particles that can interfere with the proper closing of electrical contacts and can lead to additional costs.
- the invention aims at a simple, inexpensive and robust design that optimizes the switching time of an auxiliary contact in a coil supply circuit, stably whatever the conditions of use of the switch device.
- the device must avoid any premature decrease of the coil inrush current during most of the call phase.
- the device allows the circulation of a holding current less than the inrush current.
- the device must avoid any increase unintentional residual current coil, during most of the phase of settles.
- the solution must be able to ensure very fast switching of the auxiliary contact.
- the device is characterized in that the mechanical means comprise a slider acting on a movable contact bridge of the auxiliary contact and provided with a first arm and a second arm, and a finger secured to the movable pallet, placed between both arms and acting on the first arm to actuate the slider in one direction and on the second arm to operate the slider in an opposite direction.
- the mechanical means comprise a slider acting on a movable contact bridge of the auxiliary contact and provided with a first arm and a second arm, and a finger secured to the movable pallet, placed between both arms and acting on the first arm to actuate the slider in one direction and on the second arm to operate the slider in an opposite direction.
- the mechanical means comprise two compression springs cooperating to realize a mechanism for exceeding dead point in the race of the slider. Thanks to this mechanism, we ensure advantageously a quick break of the auxiliary contact.
- the distance between the finger and the first arm of the slide in the rest position generates a neutral call for the finger.
- the distance between the finger and the second arm of the slider in the working position generates a neutral stroke of fall for the finger.
- a low voltage electrical switch device in particular a contactor, relay, circuit breaker or contactor-breaker is responsible for switching a load electric, such as an electric motor, thanks to mobile pole contacts may be plated or separated from fixed pole contacts.
- each pole of the apparatus has two fixed contacts cooperating with two movable contacts fixed on a pole contact carrier, movable between a rest position R and a working position T.
- the pole contacts are plated in the working position T.
- so-called "opening" contacts the pole contacts are plated in the R. rest position.
- the control electromagnet of the device has an excitation coil 20, of the type supplied with direct current, and a magnetic circuit comprising a movable pallet which is integral with the movable contact carriers pole.
- the mobile pallet is driven in one direction when the excitation coil is traversed by a current electrical excitation.
- the movable pallet is driven in the other direction by a spring and / or possibly magnets for example, in the absence of current coil.
- the main excitation coil 20 of a electromagnet control is connected in series with a resistive component between terminals A1, A2 of the power supply circuit coil of a switch device.
- the resistive component consists of one or preferably two resistors 25a, 25b connected in parallel so as to generate a heating less in each resistance, compared to a resistive component of the same value but which would consist of a single resistance.
- An auxiliary contact 10 that may be the open state O or the closed state F is connected in parallel with the resistors 25a, 25b, of in order to be able to shunt the resistors 25a, 25b when it is in the closed state F. also consider equivalently to use three or more resistors in parallel.
- FIG. 2 shows a first curve representing in a simplified way the displacement curve of the moving pallet as a function of time.
- the pallet In his position initially, the pallet is assumed to be in the R rest position. excitation sufficient l runs the coil 20, the movable pallet is driven by a electromagnetic force from the rest position R to the working position T. This step corresponds to the call phase marked P1.
- the P1 call phase requiring a lot of energy, the auxiliary contact 10 must therefore be closed during the call phase P1 to have a maximum current l in the coil 20 and must remain closed the longest possible to facilitate the movement of the pallet towards the position T.
- the pallet is simply maintained in work position T and the energy requirement is lower.
- the auxiliary contact 10 must then remain open in order to reduce the current consumed in the coil 20, which avoid heating it unnecessarily or even seriously damaging it.
- the coil current l disappears or goes down below a threshold predetermined value (for example corresponding to a residual voltage across the coil equal to 10% of the nominal voltage, according to IEC947-1), the coil is more able to maintain the pallet in working position T and the return spring causes the pallet to the rest position R, which constitutes the fallout phase, denoted P3. he however, it is important that the auxiliary contact only be closed at the end of this phase P3. Indeed, its premature closure will cause an increase in the current residual circulating in the coil 20 and therefore the electromagnetic force.
- a threshold predetermined value for example corresponding to a residual voltage across the coil equal to 10% of the nominal voltage, according to IEC947-1
- the auxiliary contact 10 is actuated by the mobile pallet at using mechanical means.
- These mechanical means must therefore be arranged to meet the requirements raised above, ie for the open state O of contact 10 occurs shortly before the end of the mobile pallet stroke in position T and so that reciprocally the closed state F of the contact 10 occurs little time before the end of travel of the moving pallet in position R.
- the auxiliary contact 10 has a movable bridge 11 moving along a translation axis X and bearing movable contact elements cooperating with fixed contact elements 15.16.
- FIG. 4a shows the auxiliary contact 10 in the closed state F in which a current circulates between the terminals 18, 19 of the auxiliary contact 10.
- Figure 4c shows the contact auxiliary 10 in the open state O.
- the movable bridge 11 of the auxiliary contact 10 is actuable by mechanical means 21,30.
- these means mechanical devices comprise a slider 30 connected to the movable bridge 11 and a finger 21 secured to the movable pallet and acting on the slider 30.
- the slider 30 is movable along the axis of translation X. It comprises a body longitudinal direction from which depart to the same side, for example perpendicular to the axis X, a first arm 31 and a second arm 32 remote from the first arm 31.
- the movable bridge 11 is attached to the slider 30 via a contact pressure spring 14 and 37. A first end of the pressure spring 14 bears against one end 35 of the body of the slider 30 and the other end of the spring 14 takes support against the moving bridge 11.
- a finger 21 attached to the movable pallet either directly, or indirectly using, for example, an intermediate connecting piece any.
- a displacement of the pallet thus causes a movement of the finger 21 along the axis X.
- the finger 21 is arranged so that it can drive the slide 30 in a direction RT (that is to say, rest to work) while bearing on the first arm 31, and drive the slider in an opposite direction TR (ie Work to Rest) in bearing on the second arm 32.
- a first end of two compression springs 33,34 At a point 38 of the body of the slider 30 are fixed a first end of two compression springs 33,34.
- the other end of springs 33,34 is attached to 43.44 fixing points of the housing of the device.
- Both springs 33,34 and the 43,44 attachment points extend from both sides of the slide 30 symmetrically relative to the axis X.
- the springs 33,34 thus realize a mechanism of overtaking of dead point M in the race of the slider.
- the median dead point M is formed by the intersection between the X axis and the perpendicular axis formed by the points 43,44 and corresponds to the maximum compression of springs 33,34.
- the electrical apparatus also comprises stop means 42, 45, for example formed by the housing of the device, against which the ends of the body of the slide 30 are supported so as to limit its movements.
- the finger 21 linked to the moving pallet is in rest position R.
- the slider 30 is pushed by the springs 33,34 in the direction TR and one end of the body of the slider, close to the second arm 32, rests against a stop 42.
- the springs 33,34 thus hold the slide 30 in the rest position R.
- the auxiliary contact 10 is then in the closed state under the action of the pressure spring 14 on the movable bridge 11, to maintain a satisfactory contact pressure.
- Strength exerted by the springs 33,34 along the axis X is greater than that of the spring 14 of to maintain the slider 30 in the R position and to ensure a good pressure for closing the auxiliary contact 10.
- the distance between the finger 21 and the first arm 31 is equal to a value Cn1.
- the finger 21 When the current flowing through the coil 20 is sufficient to move the moving paddle, the finger 21 will start a move in the RT direction. This displacement has first a neutral call course corresponding to the length Cn1, before the finger 21 comes into contact with the first arm 31. Then the finger 21 causes the slider 30 via the arm 31 until the point 38 cross breakeven M, going through a race marked Cp1 (Fig. 4a). Strength generated by the pallet is obviously much greater than the force exerted by the 33,34 springs along the X axis, so that the finger 21 can easily cause the slider 30 to neutral M, without disturbing the operation of the pallet.
- Figure 4b shows the passage of the neutral point M in the RT direction.
- the finger 21 always drives the first arm 31 and the contact auxiliary 10 is always in the closed state.
- the force exerted by the springs 33,34 will reverse and will cause the slider 30 in the RT direction, without encountering resistance, until the end 35 of the slide near the spring 14 rests against a stop 45, in traveling a distance marked Cp2 (see Fig. 4c).
- the slider is actuated by the springs 33,34.
- the spring 14 relaxes then completely and the auxiliary contact 10 goes to the open state, for example thanks to the stop 37 of the slide 30.
- the device is designed so that the opening of the contact auxiliary 10 preferably occurs at the beginning of the path Cp2, when point 38 is at a distance beyond the dead point M.
- the position thus obtained is the working position T shown in Figure 4c.
- the arm 31 is no longer secured to the finger 21, and the position is stable thanks to the mechanism of overflow of neutral of the stroke of the slider which pushes the slide against the stop 45.
- the distance between the finger 21 and the second arm 32 is equal to a value Cn2.
- the pallet leaves the position T under the action of the return means and the finger 21 therefore starts a displacement in the opposite direction TR.
- This move includes first a neutral fallout race corresponding to the length Cn2, before the finger 21 does not come into contact with the second arm 32.
- the finger 21 causes the slide 30 through the arm 32 until the point 38 crosses the neutral point M, by traversing the stroke Cp2 in the direction TR.
- the force generated by the pallet is obviously much greater than the force exerted by the springs 33,34 according to the axis X, so that the finger 21 can easily lead the slide 30 to neutral, without disrupting the operation of the pallet.
- the auxiliary contact 10 preferably switches to the closed state F shortly before the end of the stroke Cp2 in the direction TR, when the point 38 is at the distance d before the dead point M.
- Figure 4d shows the passage of the neutral point in the direction TR.
- the finger 21 always drives the second arm 32.
- the force exerted by the springs 33,34 goes reverse and will very quickly drive the slide 30 in the direction TR, until that the end of the slide near the second arm 32 rests against the abutment 42, by traversing the distance Cp1.
- the race traveled in the RT direction between the R and T positions by the finger 21 is therefore equal to (Cn1 + Cp1 + z1).
- This distance from safety z1 corresponds to the distance traveled by the finger 21 after the crossing from the dead point M by the slider 30. It is essential to guarantee, whatever the tolerances of the different mechanical parts of the switch the finger 21 will always take the slider 30 beyond the dead point M and therefore that the slider 30 will be able to open the auxiliary contact 10.
- the race traveled in the direction TR by the finger 21 is equal to (Cn2 + Cp2 + z2) between the positions T and R, the safety distance z2 having the same utility in the direction TR as the distance z1 in the RT direction.
- the stroke traveled by the slider 30 in the RT or TR directions is equal to (Cp1 + Cp2), the neutral point M being substantially in the middle of this race.
- the opening O of the auxiliary contact 10 will therefore be effected after a stroke Cn1 of the finger 21 and then a stroke (Cp1 + d) of the slide 30.
- the closure F of the auxiliary contact 10 will be effected after a stroke Cn2 of the finger 21 and then a stroke (Cp2 - d) of the slide 30.
- the hysteresis generated by the mechanical means of connection between the mobile pallet of the control electromagnet and the auxiliary contact of the coil supply circuit is therefore primarily related to the existence in the RT sense of the call neutral race Cn1 which separates the finger 21 of the first arm 31, and in the direction TR of the neutral stroke of fallout Cn2 which separates the finger 21 from the second arm 32.
- the invention thus makes it possible to to conceive a simple hysteresis, economic but of great precision notably thanks to the fact that it contains only purely mechanical elements.
- a race Cp1 and a stroke Cp2 equal to 2mm, a stroke Cn1 equal to 3,5mm, a stroke Cn2 equal to 3,9mm, a distance d equal to 0.3mm, a safety distance z1 equal to 0.9mm and a safety distance z2 equal to 0.5mm.
- the stroke of the finger 21 is then 6.4mm in both directions and that of the slider 30 is 4mm.
- the opening of the auxiliary contact 10 occurs 5.8mm after the position R, that is to say say when the moving paddle has traveled about 90% of its RT stroke.
- the open state O therefore occurs well near or at a moment near the end of the 6.4mm race moving the moving pallet to working position T.
- the kinetic energy stored by the palette in motion until this moment is then sufficient to make him perform the Remaining 10% to achieve T position under satisfactory conditions for the switch device, despite the opening of the auxiliary contact 10 and therefore the decline current flowing in the coil 20.
- the closing of the auxiliary contact 10 takes place at a distance of 5.6mm after the position T, that is to say when the pallet mobile traveled about 87% of the TR race.
- the closed state F thus occurs well at near or at a moment near the end of the 6.4mm stroke bringing the pallet in the rest position R.
- the magnetic circuit of the pallet is then sufficiently open for the closure of the auxiliary contact 10, generating a increase of any residual current circulating in the coil 20, can no longer harm significantly to the completion of the remaining distance to reach the position T satisfactorily for the switch device.
- the hysteresis generated by the mechanical means 30 must allow the open state O of the auxiliary contact 10 during the call phase P1 to occurs when approximately 80% of the stroke brings the moving pallet into position Work T has already been done to avoid the disadvantages mentioned above.
- the hysteresis created by the mechanical means 30 must allow the closed state F of the auxiliary contact 10 during the fallout phase P3 only occurs when about 80% of the stroke bringing the mobile pallet to rest position R has already been performed.
- FIGS. 5 and 6 of the circuit of FIG. coil power supply comprises a main coil 20, an auxiliary contact 10 and that a secondary coil 21 or 22.
- a small secondary coil 21 is added in series with the main coil 20. It is wound on the same carcass as the coil 20 but consists of a wire finer driver so much more resistive. It is shunted during the P1 call phase when the auxiliary contact 10 is closed F. If the contact 10 is closed, the resistance of the coil 20 is weak and the current is maximum. Then, when the contact 10 is open, the resistance increases sharply due to the more resistive conductive wire of the coil secondary 21 and the coil supply circuit then consumes less current.
- the secondary coil 22 is connected in parallel with the main coil 20 only when the auxiliary contact 10 is closed, in the P1 call phase.
- the coil 20 is dimensioned to ensure the phase of P2, during which the auxiliary contact 10 is open, the resistor then being increased and power consumption decreased.
