Definitions

  • the present invention belongs to the field of electric switches and/or circuit breakers, particularly suitable for extinguishing the electric arc occurring when opening and closing the contacts thereof.
  • an object of the present invention is to provide a current breaker switch, which allows quickly and effectively extinguishing electric arcs occurring in an electric circuit during the cutting off and closing operations thereof, all in a smaller volume.
  • Another object of the invention is to provide a reconfigurable current switch, such that the internal contacts of the switch are connected in series during the transitory process to cut off current or to connect current in order to cut off the current at several points and to facilitate extinguishing the arc, and those same contacts are connected in parallel during the permanent current conducting state of the switch in order to divide the current into several branches and to thus reduce the temperature of the conductive material.
  • the switch of the invention is particularly applicable to cutting off high power direct current, where it is more difficult to extinguish the electric arc than in alternating current.
  • switch cut-off mechanisms usually entails some type of impact between parts which, in the long-term, cause the material to deteriorate by wear which can lead to destruction of the switch.
  • Patent US-3120585A refers to a rotary switch with replaceable contact sets, and having a insulator rotor shaft 18 carrying a first and second series of moving contact members arranged in linear spaced array, such as when the rotor is turned, the moving contacts engage the respective stationary contacts.
  • the rotor does not move linearly along an axis.
  • Patent US-4841833A refers to a switch for An electromagnetic projectile launcher, wherein a firing switch which alternately opens and closes to repeatedly commutate current from a high current supply to a pair of projectile launching rails.
  • a rotor having a transverse conducting element is rotated within and moved axially along a cylindrical stator.
  • Patent application EP-1267373A1 refers to a power control apparatus.
  • Patent application EP-0741399A1 refers to a gas-dielectric high-tension interrupter of the arc-puffer type
  • the present invention solves the drawbacks discussed above, providing a current breaker switch that simultaneously and synergistically integrates several arc extinguishing techniques, quickly and effectively breaking the electric arc in a smaller space and in one and the same time instant.
  • a first aspect of the invention relates to an electric current breaker switch, comprising at least one pair of fixed contacts and one moving contact movable between a closed position of the switch in which it establishes electrical continuity with the fixed contacts, and an open position in which it cuts off current circulation.
  • the linear switch further comprises a rotor made of an insulating material that is movable defining a movement at least with a linear component with respect to an axis, such that at least one pair of moving contacts are assembled in the rotor and configured such that they have two ends accessible through two different points on the outer surface of the rotor.
  • connection means external to the rotor are arranged and configured for connecting the moving contacts in series or in parallel, specifically in series in the transition process of the switch, and in parallel in the permanent conducting state.
  • connection means can consist of a first and a second pair of soleplates (or brush) placed adjacent to one another and arranged for being contacted by a first end of the moving contacts.
  • the moving contacts and the soleplates are relatively placed with respect to one another and/or configured such that as the rotor moves, in a first axial position of the rotor, precisely in the state transition of the switch from cut-off to conduction or vice versa, the moving contacts are connected to one another in series through the soleplates in order to cut off the current at several points or close the switch at several points, to thus reduce the intensity of the arc and facilitate extinguishing it.
  • the moving contacts of the rotor are connected to one another in parallel through the soleplates in order to divide the current circulation into several branches and to thus reduce the temperature generated in the conductive material.
  • the current switch object of the invention is therefore reconfigurable because the internal contacts of the switch are connected in series during the transitory current cut-off process, and those same contacts are connected in parallel during the permanent current conducting state of the switch.
  • the movement of the rotor to produce the series-parallel-series connection of the moving contacts is a combination of a rotational movement and a linear movement with respect to the axis of the rotor.
  • the rotor is movable in a helicoidal manner, which includes a component having a rotational movement and simultaneously a component having a linear movement.
  • the rotor is movable in a sequence of two movements, a first rotational movement alone and second linear movement alone, both with respect to the same axis.
  • the moving contacts rotate integrally with the rotor, so they are movable following a helicoidal movement about an axis passing through the center of the moving contacts, or alternatively with the sequential movement mentioned above.
  • the helicoidal movement of the moving contact with respect to the fixed contacts is a combination of radial movement together with longitudinal movement of the moving contact, which has the effect of achieving a longer separation length between contacts (lengthening the electric arc) for extinguishing the arc quickly and in a smaller space.
  • the invention thereby successfully lengthens the electric arc in helicoidal form without requiring a larger volume of air, which means that for one and the same rated cut-off current, the switch can be smaller compared to a switch of the state of the art.
  • the reconfigurable switch of the invention allows connecting the moving contacts thereof in series to promote current cut-off upon connection, and connecting them in parallel in a stable situation of the switch once the current cut-off function ends.
  • the moving contacts remain connected in series when there is electric current circulating through the switch, the moving contacts would generate more heat than if they are in parallel, whereby the switch would heat up considerably and have energy losses.
  • the switch heats up less so there are fewer energy losses, and it further allows the same switch to work with more thermal allowance. For example, it is necessary today to oversize copper contacts in the heating portion so that they heat up less in order to meet UL standards for the North American market.
  • the switch of the present invention with a simple structure is capable of connecting the same internal contacts one way to perform more critical work, i.e., cutting off or opening an electric current with the occurrence of an electric arc, and of connecting them in another more optimal way for when the current cut-off function has ended.
  • FIG. 1 shows an embodiment of an electric switch (1) according to the invention comprising a stator (11) including a casing (7,7') made of an insulating material intended for being assembled in a fixed position of an electric installation, for example in a switchboard box, and can be formed by two halves (7,7') coupled to one another.
  • the stator (11) internally forms a generally cylindrically-shaped chamber (3) in which a rotor (2) made of an insulating material is housed, and such that the rotor (2) is suitable for moving axially inside said chamber and with respect to its axis of revolution (X).
  • the rotor moves axially while at the same time it rotates with respect to axis (X), whereby it performs a helicoidal movement with respect to said axis (X).
  • a pair of fixed contacts (4,4') are assembled in said casing (7,7') and have respective contact surfaces (6,6') arranged for being contacted by a moving contact (9), for which they are curved in correspondence with the curvature of the outer surface of the rotor (2).
  • the rotor (2) in turn incorporates at least one moving contact (9) which rotates integrally with the rotor and therefore also defines a helicoidal movement about the axis "X".
  • the fixed contacts (4,4') and the moving contact (9) are arranged for coming into contact in the closed position of the switch (1) ( Figure 2c ), whereas in the electrical cut-off position of the switch ( Figures 1 and 2b ), they do not allow current circulation.
  • the fixed contacts (4,4') are arranged in a diametrically opposed manner with respect to the axis of revolution (X) of the rotor (2).
  • the stator and the rotor are configured forming a complementary threaded coupling therebetween.
  • that threaded coupling consists of one or more channels (44) with a helicoidal trajectory existing on the inner surface of the stator (11), and a pair of metal balls (39,39') coupled in diametrically opposed points of the rotor (2) and sliding through said channels.
  • the balls are arranged in a cylindrical sector (43) formed in said rotor (2), such that the rotor forms a type of bearing.
  • the rotor (2) is operated by conventional external means, for example a connecting rod (17) coupled with a lug (18) projecting from the rotor, which is in turn operated by any suitable mechanism.
  • Said operating means cause the movement of the rotor in one direction or the other, i.e., reciprocally, along the axis (X) between a closed position and an electrical cut-off position of the switch.
  • the helicoidal rotation of the rotor (2) is performed by means of external threading means outside the casing, specifically by means of an external body (29) outside the casing as shown in Figure 5 , such that an elongation (2') of the rotor (2) is housed inside that body (29) and rotates about it by means of a threaded coupling (30) formed in a complementary manner in both elements (29, 2').
  • the friction between the rotor (2) and the casing (7) is minimum since the rotor rest primarily on the body (29), so contact would only exist between the moving contacts and the casing or fixed contacts (not depicted in that drawing).
  • the prolongation (2') of the rotor (2) consists of a body axially coupled at a end of the rotor (2) outside the chamber (3) of the casing (7,7').
  • the rotor (2) is operated by external means acting on one of its free ends (37).
  • the external body (29) is fixed, for example, it can be fixed to the casing (7) itself or to another fixed element of the switch.
  • the switch of the invention can incorporate the electric arc breaking by means of the serial connection of contacts.
  • the switch includes two or more moving contacts (9) assembled in the rotor in the same position (same angular position with respect to the axis) but at a different axial position.
  • One or more soleplates (19,19', 42,42') made of a conductive material are assembled in the stator (11) outside the rotor, and are arranged such that in the electrically closed position of the switch, they connect the moving contacts (9) between the fixed contacts (4,4') in series as is shown more clearly in Figure 3b , in which the arrows indicate the electric current circulation direction.
  • the arc is thus split at several cut-off points, so it is easier to extinguish.
  • a pair of metal connection terminals (22,22') in the form of a plate serve to electrically connect the switch with an external circuit, and are arranged in opposite portions of the casing (7,7') and electrically connected with the fixed contacts (4,4') with which they are in contact.
  • the rotor (2) has a closed front end (37) and an open rear end (38) providing access to the inner hollow portion of the rotor, such that a suction valve (24) can be coupled to that open end.
  • the valve (24) is assembled in a fixed position in the rear portion of the casing (7,7'), and has projections (26) to prevent rotation.
  • the valve (24) is configured for being inserted into the rotor when the rotor moves towards said valve in its end position, in the movement to cut off power. As the rotor moves back, it is uncoupled from the valve (24) and causes suction inside the rotor, suctioning the electric arc. To allow that suction, the rotor has through holes arranged on the edges of the moving contacts.
  • the closure valve (24) In the electrically closed position of the switch, the closure valve (24) does not seal the rotor, as seen in Figure 2b , so it allows air to circulate towards the inside thereof.
  • the suction valve (24) is cylindrical-shaped and made of a rigid or flexible elastic insulating material.
  • the rotor (2) has at least one through conduit (40) communicating the inside of the rotor with the outside, which performs the function of a chimney in the closed position of the switch through natural ventilation, such that the hot air circulates towards the soleplates and is released through the gaps and clearances between the output terminals.
  • the same through conduit (40) is used to released the gases drawn in by the valve (24) through the holes of the moving contacts, providing direct output aligned with the windows of the stator (14 and 14').
  • Ventilation windows (14,14') existing in the stator allow viewing the position of the moving contacts (9,9',9") inside the rotor such that the state of the switch can be visually inspected, which can be useful, for example, for an operator performing maintenance tasks.
  • the configuration and arrangement of the fixed and moving contacts of this embodiment is best seen in Figure 2 .
  • the rotor (2) is partially hollow and has three groups of moving contacts (9,9',9"), each group formed by two or more metal plates (5,5') that are superimposed and in electrical contact, which are generally rectangular-shaped and housed inside the rotor, such that they rotate integrally with the helicoidal movement of the rotor.
  • the ends of the plates (5,5') slightly project through holes (8) of the rotor (2) located at diametrically opposed points thereof.
  • the ends of the plates (5,5') are curved (in the form of an arc of circumference) in correspondence with the curvature of the curved surfaces (34,34'), being flush with same.
  • the position of the three groups of moving contacts (9,9',9" in the rotor is the same as seen in Figure 5b , but at a different axial level with respect to the axis (X).
  • the switch incorporates as fixed contacts an upper pair of soleplates (19,42) assembled in an upper fixed position of the stator (11) (in the normal use position of the switch), and a lower pair of soleplates (19',42') assembled in a lower fixed position of the stator (11).
  • Both the upper pair of soleplates (19,42) and the lower pair of soleplates (19',42') are aligned according to the longitudinal span of the rotor (2) and are adjacent to in pairs.
  • more than two groups of adjacent soleplates and three or more moving contacts can be arranged on each side of the rotor depending on the current cut-off needs.
  • insulating plate located between the two conductor plates of each pair, specifically a first insulating plate (41) placed between the two upper conductor plates (12,42), and a second insulating plate (41') between the two lower conductor plates (12',42').
  • the soleplates (19,42,19',42') are permanently pressed against the groups of moving contacts (9,9',9") or the rotor (2) by elastic means, in this case by means of a pair of upper springs (23) and a pair of lower springs (23').
  • the switch incorporates a pair of fixed contacts, specifically an upper fixed contact (4) in electrical contact with only the soleplate (42) and a lower fixed contact (4') in electrical contact with only the soleplate (19') as seen more clearly in Figure 3a .
  • the soleplates (19,42') are not connected to another element of the switch and serve for connecting the moving contacts (9,9',9") to one another.
  • the rotor (2) incorporates ventilation fins (32,32') which rotate integrally therewith and serve to move the air around the rotor inside the chamber (3) and expel it out through the ventilation windows (14,14') of the stator (11) for the purpose of improving the reduction of the switch temperature.
  • the ventilation fins (32,32') preferably extend along the rotor according to a line parallel to the axis (x).
  • the rotor (2) has two bevels consisting of two planar surfaces (33,33') parallel to one another arranged on diametrically opposed sides of the rotor with respect to its axis (x), and two curved surfaces (34,34') with the curvature of an arc of circumference arranged on diametrically opposed sides of the rotor with respect to its axis (x).
  • the rotor can be a complete cylinder.
  • the fins (32,32') project from said planar surfaces (33,33') and further have the additional advantage of increasing the outline of the rotor and therefore increasing the leakage path of the electric arc, so the electric insulation is improved, complying with the most demanding regulations concerning insulation, and all this in a smaller space.
  • the rotor (2) incorporates respective channels (35,36') extending along same.
  • the moving contacts (9) project in both curved surfaces (34,34') and have ends with the same curvature.
  • the three groups of moving contacts (9,9',9") rotate simultaneously with the rotor (2) defining a helicoidal movement with respect to the axis of rotation (X) of the rotor, so while moving longitudinally in the direction of the axis (X) (from left to right in the figure), they rotate with respect to that axis.
  • the moving contacts (9,9',9") are at an angle of 0° in the horizontal position, in an open position (no electrical connection) of the switch.
  • Figure 3b the ends of the moving contacts have approached the pairs of upper and lower conductor soleplates (19,42, 19',42'), but there still is no electrical connection.
  • a first end of the first group of moving contacts (9) is in contact with the soleplate (19'), and a second end of that same contact is in contact with the soleplate (19).
  • a first end of the second group of moving contacts (9') is in contact with the soleplate (42'), and a second end of that same contact is in contact with the soleplate (19).
  • a first end of the third group of moving contacts (9") is in contact with the soleplate (42'), and a second end of the same contact is in contact with the soleplate (42).
  • the rotor (2) continues to rotate in the same direction, so the moving contacts (9,9',9") move forward sliding respectively over the soleplates (19,42, 19',42'). reaching a rotation position of 45° ( Figure 3e ), in which the moving contacts continue to be connected in series, but where the upper end of the second group of moving contacts (9') is very close to the soleplate (42).
  • the first group of moving contacts (9) is always connected between the soleplates (19,19'), and the third group of contacts (9") is always connected between the soleplates (42,42'). It is only necessary for the second group of moving contacts (9') to change the connection and to go from being connected between the soleplates (19,42') to being connected between the soleplates (19,42) and the soleplate (42').
  • Figure 5 depicts an alternative embodiment of the movement of the rotor and moving contacts to cause the series-parallel-series connection, which instead of being helicoidal such as in the case of the preceding drawings, is a sequence of movements with a first rotational movement about an axis of rotation followed by a second linear movement along that same axis.
  • Both embodiments have in common the fact that the series-parallel-series reconfiguration of the moving contacts is performed by means of a linear movement of those contacts, together with rotation in the case of helicoidal movement, and without rotation in the case of the embodiment of Figure 5 .
  • the current cut-off process would be the reverse, i.e., moving the rotor from the position of Figure 5g to Figure 5a .
  • the switch incorporates or has associated therewith operating means, such as a control or push button which, by means of a suitable manual or automatic mechanism, performs the two movements of the rotor described above.
  • operating means such as a control or push button which, by means of a suitable manual or automatic mechanism, performs the two movements of the rotor described above.
  • the person skilled in the art is familiar with the mechanisms for operating such switches, so he said person would know how to implement those operating means.
  • the rotor (2) is made of glass, which provides the additional advantage of that material being an excellent insulating material with high dielectric strength, and it is highly resistant to deterioration caused by the electric arc, compared with plastic insulating materials conventionally used in the state of the art, which in turn significantly prolong the service life of the switch.
  • the rotor can also be made of porcelain, obtaining the same advantages discussed above with respect to glass.
  • the switch developed in this invention is capable of achieving in one and the same instant and with a single movement at least three effects, namely:
  • the particular structure of the switch allows it to be smaller because it is not necessary to have air chambers between contacts, being able to reach a size reduction of about 50% with respect to a conventional switch for the same cut-off power.
  • the operation of the switch does not entail the abrupt impact between any of its parts, which increases the service life of the switch and increases its reliability.
