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.
  • 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.
  • German patent application DE-10 2011 118713 A1 relates to a single- or multi-pole switching device, in particular for DC applications, having at least one rotating switching element (2) and also comprising switching contacts (4, 5).
  • Patent application EP-1267373A1 refers to a power control apparatus.
  • Patent US-4426562 relates to a rotary switch for switching very large DC currents.
  • the present invention solves the drawbacks discussed above, providing a current breaker switch that can simultaneously and synergistically integrate 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:
  • the rotor is configured, i.e., it has a shape and size 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, preferably all, of the contact surface of the fixed contacts, such that the electrical cut-off operation (i.e., going from switch conduction to the power being cut off) is performed by means of the instantaneous interposition (in the same instant the power is cut off) of a solid material, such as the insulating material of the rotor, instead of the insulating means being air, oil or another insulating liquid, like what occurs in switches of the state of the art.
  • the rotor can be configured for rotating on the same plane, i.e., without axial movement, so the fixed contacts and the moving contact can be coplanar, such that the moving contact is movable on said plane to perform the operations of closing and opening the switch.
  • the rotor is movable following a helicoidal movement about an axis, such that the moving contact assembled in the rotor also moves with that helicoidal movement.
  • the helicoidal movement of the moving contact with respect to the fixed contacts is a combination of rotational movement together with longitudinal movement of the moving contact with respect to one and the same axis, 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.
  • Figure 1 shows an embodiment of a switch for solid cut-off according to the invention, comprising: a rotor (2) made of an insulating material that is rotational with respect to an axis (X), at least one moving contact (9) assembled in the rotor (2), and at least one pair of fixed contacts (4,4') respectively having a contacting surface (29,29') arranged for being contacted by the moving contact (9) in the electrically closed position of the switch.
  • the rotor (2) is movable between a closed position of the switch ( Figure 1 a) in which the moving contact (9) establishes electrical continuity with the fixed contacts (4,4'), and an open position ( Figure 1c ) in which the moving contact (9) is not in contact with the fixed contacts (4,4') and current circulation is prevented.
  • the rotor (2) is configured such that in the open position ( Figure 1 c) of the switch, the rotor is in direct contact with the fixed contacts (4,4') and covers the entire contacting surfaces (29,29') of the fixed contacts (4,4') to electrically insulate them. It can be seen in Figure 1c that the rotor is interposed between the fixed contacts (4,4'), and the moving contact (9), preventing or at least complicating the occurrence of the electric arc.
  • the rotor (2) has a side contact surface (30) arranged for sliding on the fixed contacts (4,4'), specifically on the respective contacting surfaces (29,29'), such that that contact ing surface (30) is formed to an extent by an end of the moving contact (9) and to a larger extent by rotor (2) itself.
  • the rotor (2) is a circular disc or a cylinder, so the contacting surface (30) has the curvature of an arc of circumference of center the axis of rotation (X) of the rotor (2).
  • X axis of rotation
  • the fixed contacts (4,4') are equidistant with respect to the axis (X) and are preferably arranged in a diametrically opposed manner with respect to the axis of rotation (X) of the rotor.
  • the moving contact (9) is housed in the rotor (2) and is configured such that it has ends (31,31') projecting in diametrically opposed sides of the rotor (2).
  • the rotor (2) has a circular section having a diameter coinciding with the separation distance between the fixed contacts (4'4') so with the rotation of rotor (2) the contacting surface (30) slides in permanent contact with the fixed contacts (4'4') by means of the contacting surfaces (29,29').
  • That interposition of a solid medium occurs at the same time in the two fixed contacts (4,4'), i.e., double insulation at two different points.
  • contact between the rotor (2) and the fixed contacts (4'4') can be done under pressure, for example by means of springs pressing the fixed contacts (4,4') against the rotor (2) (as indicated by the arrows in Figure 1a ), such that since the fixed contacts (4,4') are in the form of a flat bar, they have certain bending capacity.
  • the electric insulation between the two fixed terminals (4,4') is thus significantly enhanced, so it is even more difficult for an arc to be generated.
  • the fixed contacts (4,4') and the moving contact (9) are coplanar, and the moving contact (9) is rotational on said plane, i.e., there is no axial movement of the rotor.
  • the rotor (2) is movable defining a helicoidal movement about the axis of rotation (X), and reciprocally between a closed position and an electrical cut-off position of the switch, as shown in Figures 2 to 5 .
  • Figure 2 shows 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 switchboard, 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) 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 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 housed in the rotor, such that the two ends (31,31') 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 3 ), whereas in the electrical cut-off position of the switch ( Figures 4 and 5 ), the fixed contacts (4,4') are in contact with the insulating material of the rotor (2).
  • 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 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 3d ), 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 threaded coupling therebetween in a complementary manner.
  • the rotor has on its outer surface one or more channels (15) with a helicoidal trajectory, cooperating with ribs (16) with a similar shape that are inserted in said channels.
  • 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 person skilled in the art will understand that other configurations are possible for obtaining said threaded or screw configuration between rotor and stator for the purpose of causing the helicoidal movement of the rotor.
  • 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 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.
  • 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 in at least one of 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 3b , 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 front and rear valves (25,24) are cylindrical-shaped and made of an insulating material, for example a rigid or flexible plastic material.
  • the rotor (2) has a through conduit (28) in at least one of the holes (8), preferably located in a corner of the holes, which 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 3d , 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 3d .
  • 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 seen in Figure 3a , with which the rotor moves axially and defines a helicoidal trajectory in the direction of arrow "A" of Figure 4b , while at the same time the rear closure valve (24) seals the rear opening 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 until they are no longer connected with the plates (19,19') and with the fixed contacts (4,4'), so current circulation is cut off, as seen in Figure 4c .
  • 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 conduits (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) 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 prolongs 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 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.
