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.
  • 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.
  • 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 moving contact is arranged between the fixed contacts, and it is movable following a helicoidal movement with respect to an axis.
  • 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 switch preferably incorporates a rotor made of an insulating material, in which said at least one moving contact is assembled, where the rotor is movable with a helicoidal trajectory with respect to an axis of rotation, and therefore causes the helicoidal movement of the moving contact.
  • the tangential speed of the cut-off point can be increased by simply increasing the turning radius, thus increasing the cut-off speed in a simple manner, without the need for complex mechanisms and with a smaller number of parts, so manufacturing the switch is very simple.
  • the rotor can be a cylindrical body or have a generically cylindrical shape which moves in a helicoidal manner with respect to its axis of revolution reciprocally, i.e., in both directions, to go from the closed position to the cut-off position and vice versa.
  • a pair of fixed contacts have a contact surface arranged for being contacted by a moving contact, and the rotor is configured such that in the open position of the switch, the insulating material of the rotor is in direct contact with the fixed contacts and covers most of the contact surface of the fixed contacts, so there is no air chamber around the moving contacts and the occurrence of the electric arc is reduced or made impossible.
  • the sequence of drawings shows the movement of the contacts for going from the cut-off (Off) position of the switch to the electrically closed (On) position, where the moving contacts move from left to right in the figure.
  • the reverse transition i.e., going from On to Off, is identical but follows the reverse order of the drawings, i.e., from (g) to (a), the moving contacts moving in such case from right to left in the figure.
  • the arrows indicate the path of the electric current in the On position.
  • FIG. 1 shows an embodiment of a helicoidal switch (1) for solid cut-off 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 fuse 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, defining a helicoidal movement inside said chamber and with respect to its axis of revolution (X).
  • a pair of fixed contacts (4,4') are assembled in said casing (7,7'), forming contact terminals (6,6') projecting in said chamber (3) and 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 rotor (2) is preferably at least partially hollow and has two transverse holes (8) located at diametrically opposed points thereof.
  • the moving contact (9) consists of one or more superimposed metal plates (5,5') in direct contact, and such that the two ends of the metal plates (5,5') project diametrically through said holes (8) of the rotor, being flush with its outer surface, for which purpose said ends are curved according to the curvature of the outer surface of the rotor.
  • the outer surface of the rotor (2) slides in permanent contact with the contact terminals (6,6') of the fixed contacts.
  • 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 2 ), whereas in the electrical cut-off position of the switch ( Figures 3 and 4 ), the fixed contacts (4,4') are in contact with the insulating material of the rotor (2).
  • a portion of the rotor has a dimension coinciding with the separation distance of the fixed contacts (4,4'), which can be arranged in a diametrically opposed manner with respect to the axis of revolution (X) of the rotor (2).
  • the switch further comprises at least one ring (10) made of an insulating material, assembled with rotational capacity inside the cylindrical chamber (3) of the stator (11), for which purpose the casing (7) has seatings (12) in the chamber (3) in which said rings are housed, and such that the inner surface of the rings is flush with the surface of the chamber (3).
  • the diameter of the cylindrical chamber (3) coincides with or is slightly larger than the outer diameter of the rotor (2) to allow its sliding therein in a tight manner.
  • the rotor (2) slides over said rings (10), which in turn are rotational with respect to the casing (7,7') such that the rings (10) act as bearings that facilitate the rotation of the rotor (2).
  • the rings (10) can be made from an insulating material having low friction.
  • the insulating rings (10) perimetrically surrounding the rotor (2) furthermore serve to guide the rotor (2) in its helicoidal movement and to electrically insulate the moving contacts (9).
  • the stator (11) and the rotor (2) have ventilation windows, specifically the windows (13) of the rotor and the windows (14) of the stator, which are placed such that they are superimposed in the electrically closed position of the switch (as shown in Figure 2d ), thus forming a ventilation channel communicating the inside of the rotor (2) with the outside of the stator (11), allowing ventilation of the switch and the exit of gases generated during current cut-off operations.
  • the stator and the rotor are configured forming a complementary threaded coupling therebetween.
  • the rotor has on its outer surface one or more channels (15) with a helicoidal trajectory, cooperating with ribs (16) existing inside the chamber (3) with a similar shape, such that said ribs are inserted in said channels and slide over them.
  • the stator and the rotor are threaded to one another in a manner similar to a nut and screw, where the rotor would be the rotating screw with respect to the stator.
  • the helicoidal rotation of the rotor (2) is performed by means of rotor operating means outside the casing, specifically by means of an external body (29) outside the casing as shown in Figure 5 , such that an extension (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.
  • friction between the rotor (2) and the casing (7) is minimal, because the rotor is mainly supported in the body (29), so there would only be contact between the moving contacts and the casing or fixed contacts (not depicted in that figure).
  • the extension (2') of the rotor (2) consists of a body axially coupled at an end of the rotor (2) outside the chamber (3) of the casing (7,7').
  • the external body (29) is fixed, for example it can be fixed to the actual casing (7) or to another fixed element of the switch.
  • the rotor (2) is driven 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 helicoidal 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 switch of the invention can incorporate the electric arc breaking by means of the serial connection of contacts, together with the increase in the length of the arc at each cut-off point.
  • the switch includes two or more moving contacts (9) assembled in the rotor in the same position but at a different axial position.
  • One or more plates (19,19') made of a conductive material are assembled in the stator (11) outside the rotor, which respectively incorporate footings (20,20') 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 2b , 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.
  • the plates (19,19') are permanently pressed against the fixed contacts (9) by elastic means, in this case by means of formed flat bars (21,21') placed between the plates (19,19') and the fixed terminals (4,4').
  • a pair of metal connection terminals (22,22') in the form of a plate serve to electrically connect the switch with an external circuit.
  • Said terminals (22,22') are plate-shaped 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) is open at its ends, i.e., it is a tubular body, and the switch has a rear closure valve (24) assembled in a fixed position in the rear portion of the casing (7,7,), for example by means of a support (26) attached to the casing.
  • the rear valve (24) is configured to be inserted and slid inside the rotor in a tight manner by its rear portion when the rotor moves towards said valve in its end position in the movement to cut off power.
  • the rear closure valve (24) does not seal the rotor, as seen in Figure 2b , so it allows air to circulate towards the inside thereof.
  • the switch has a front closure valve (25) assembled in a fixed position in the front portion of the casing (7,7,), for example by means of a support (27) attached to the casing.
  • the front valve (25) is housed at all times inside the rotor, specifically in its front portion, and is configured to slide inside the rotor in a tight manner, hermetically sealing it.
  • the rotor (2) can have a closed end and an open end, such as the rotor of Figure 6 .
  • the front and rear valves (25,24) are cylindrical-shaped and made of an elastic insulating material, for example a rigid or flexible plastic material.
  • the rotor (2) has at least one through hole (28) preferably located at the edge of one of the holes (8), such that said through hole communicates the inside of the rotor with the outside, and is intended for allowing suctioning the electric arc towards the inside of the rotor, as will be described below.
  • the ventilation windows (13,14) of the rotor and stator, respectively coincide, i.e., they are superimposed as seen in Figure 2d , so the inside of the rotor is communicated with the outside of the stator, allowing the natural ventilation thereof by air circulation, as indicated by the arrows of Figure 2d .
  • the moving contacts (9,9',9") inside the rotor can be seen from outside the switch, which provides the additional advantage that the state of the switch can be visually inspected, which can be useful, for example, for an operator performing maintenance tasks.
  • the rotor (2) is rotated clockwise as seen in Figure 2a , with which the rotor moves axially and defines a helicoidal trajectory in the direction of arrow "A" of Figure 3b , while at the same time the rear closure valve (24) seals the rear open end of the rotor when reaching a rotation of about 40° before cutting off current circulation.
  • the moving contacts (9,9',9") move in a helicoidal manner in the same direction, sliding over the footings (20,20') until they reach a position in which they are no longer connected with the footings and current circulation is cut off, as seen in Figure 3d .
  • the rotor (2) is configured such that in the open position of the switch, the rotor is in direct contact with the contact surfaces of the footings (20,20') and covers most of the surface of that contact surface, as clearly seen in Figure 3d .
  • One of the effects or advantages associated with that feature is that in the same instant that the footings (20,20') and the moving contacts (9,9',9") are no longer connected, the actual insulating material of the rotor (2) comes into direct contact with the footings at the same time it slides over them, so power is cut off by means of the immediate interposition of a solid material or medium, instead of air as conventionally occurs in the state of the art.
  • That interposition of a solid medium occurs at the same time in the two pairs of footings (20,20'), i.e., dual insulation, and is performed under pressure due to the pressure of elastic means, in this case springs (23,23') pressing on the contact terminals (6,6'), which are in the form of a flat bar and have certain bending capacity.
  • the electric insulation between the two fixed terminals (4,4') is thereby significantly enhanced, so it is even more difficult for an arc to be generated.
  • the rotor (2) starts to rotate, the ventilation windows of the rotor (13) start to be concealed below the rings (10), which are suitably located for such function, and the rotor itself in turn closes the ventilation windows (14) of the stator.
  • the rotor (2) approaches the rear closure valve (24) sealing the rear opening of the rotor.
  • air can only circulate through the through holes (28), such that the relative movement between the rotor and the front and rear valves (25,24), generates a suction similar to that produced by a plunger in a syringe, which suctions the electric arc towards the inside of the rotor, which in turn entails stretching the arc and cooling the cut-off area due to the suction current.
  • the rotor (2) can have another shape other than being cylindrical, for example, it can have the shape of the rotor (2) shown in Figure 6 with or without fins (32).
  • Said Figure 6 depicts another preferred embodiment of the invention, in which in addition to the switch function, the moving contacts (9,9',9") and the footings are relatively placed with respect to one another and are configured in such a manner that as the rotor moves with its helicoidal movement about the axis (X), i.e., by means of a combination of simultaneous linear and angular movements, the connection of the moving contacts by means of the footings is switched from a series connection to a parallel connection and vice versa in the reverse operation.
  • the footings connect the moving contacts in series for the purpose of having several cut-off points in series and thereby splitting the arc and making it easier to put out.
  • the switch of Figure 6 comprises likewise a stator (11) including a casing made of an insulating material formed by two halves (7,7') coupled to one another, inside which there is a chamber (3) in which a rotor (2) made of an insulating material is housed.
  • a stator (11) including a casing made of an insulating material formed by two halves (7,7') coupled to one another, inside which there is a chamber (3) in which a rotor (2) made of an insulating material is housed.
  • there are no insulating rings (10) as in the case of Figure 1 instead the rotor (2) forms a cylindrical sector (43) with which it is supported and slides over a complementary surface (45) formed internally in the stator (11).
  • the rotor (2) is likewise hollow and movable with a helicoidal movement with respect to its axis of revolution (X) inside the chamber (3), the stator and the rotor are configured forming a complementary threaded coupling therebetween.
  • said threaded coupling in the embodiment of Figures 6 and 7 , consists of a pair of metal balls (39,39') placed at diametrically opposed points of the rotor (2), particularly of a cylindrical sector (43) formed in said rotor (2), such that the rotor forms a type of bearing.
  • stator (11) has on the inner surface of the chamber (3) a pair of channels (44,44') having a helicoidal trajectory cooperating with the balls (39,39') such that each ball slides along a channel to produce the movement of the rotor (2) with that trajectory with respect to its axis of revolution (X).
  • the rotor (2) can be assembled in an external body outside the stator (11) and be threaded in that external body as in the embodiment of Figure 5 .
  • the stator (11) and the rotor (2) have ventilation windows, specifically the windows (40) of the rotor (2) and the windows (14,14') of the stator (11), for ventilating the inside of the switch, to which the ventilation fins (32) of the rotor (2) contribute in this embodiment by stirring the air inside the chamber (3), and expelling it out through the ventilation windows (14,14') of the stator (11) for the purpose of improving the reduction of the switch temperature.
  • the configuration and arrangement of the fixed and moving contacts of this embodiment is best seen in Figures 7 and 8 .
  • the rotor (2) is hollow and has three groups of moving contacts (9,9',9"), each group formed by two or more metal plates (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) slightly project through holes (8) of the rotor (2) located at diametrically opposed points thereof.
  • the ends of the plates (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 7 , but at a different axial level with respect to the axis (X).
  • the switch incorporates as fixed contacts an upper pair of conductor footings (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 conductor footings (19',42') assembled in a lower fixed position of the stator (11).
  • Both the upper pair of conductor footings (19,42) and the lower pair of conductor footings (19',42') are aligned according to the longitudinal span of the rotor (2) and are adjacent to one another.
  • insulating plate located between the two conductor plates of each pair, specifically a first insulating plate (41) placed between the two upper conductor footings (19,42), and a second insulating plate (41') between the two lower conductor footings (19',42').
  • the conductor footings (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 conductor footing (42) and a lower fixed contact (4') in electrical contact with only the conductor footing (19') as seen more clearly in Figure 8 .
  • a pair of metal connection terminals (22,22') in the form of a plate serve for the electrical connection of the switch with an external circuit.
  • Said terminals (22,22') are plate-shaped and are arranged in opposite portions of the casing (7,7') and are electrically connected with the fixed contacts (4,4').
  • the rotor (2) does not have to be completely cylindrical because in this case the rotor (2) is a cylinder cut by two planes parallel to one another, defining 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 ventilation fins (32,32') are arranged in said planar surfaces (33,33') and extend along the rotor according to a line parallel to the axis (x), and they 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) further 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 rotor (2) has a closed front end (37), and an open rear end (38) which is coupleable to a suction valve (24) which causes the suction of the arc when the rotor (2) is decoupled with its movement from the valve in a manner similar to that described in relation to Figure 1 .
  • the suction valve (24) is cylindrical-shaped and made from an elastic insulating material, and it is configured to be coupled in a tight manner inside the rotor (2).
  • the rotor (2) has at least one through hole or hole (40) which communicates the inside of the rotor with the outside.
  • the rotor (2) of the embodiment of Figures 6 to 8 can be cylindrical, with one or two open ends.
  • the rotor (2) of the embodiment of Figures 6 to 8 can be operated by means of an external mechanism outside the casing (7,7'), such as that shown in Figure 5 , for example, or by means of an operating mechanism such as the one of the embodiment of Figure 1 .
  • 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 8b the ends of the moving contacts have approached the pairs of upper and lower conductor footings (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 footing (19'), and a second end of that same contact is in contact with the footing (19).
  • a first end of the second group of moving contacts (9') is in contact with the footing (42'), and a second end of that same contact is in contact with the footing (19).
  • a first end of the third group of moving contacts (9") is in contact with the footing (42'), and a second end of the same contact is in contact with the footing (42).
  • the rotor (2) continues to rotate in the same direction, so the moving contacts (9,9',9") move forward sliding respectively over the footings (19,42,19',42'), reaching a rotation position of 45° ( Figure 8e ), 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 footing (42).
  • the first group of moving contacts (9) is always connected between the footings (19,19'), and the third group of contacts (9") is always connected between the footings (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 footings (19,42') to being connected between the footings (19,42) and the footing (42').
  • the switch of the present invention with a simple structure, is capable of reconfiguring the connection of the same internal contacts in two different modes of operation in order to perform their most critical job, which is to cut off or open the electric current with the occurrence of an electric arc, and to connect them in a more optimal manner, i.e., in parallel when the current cut-off function has ended to reduce heating of the switch and energy losses.
  • 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 or other similar insulating materials, 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.
