Definitions

  • the present invention relates to an electrical appliance comprising a series of sockets and a mobile selector assembly provided with contacts cooperating with the sockets and connected to a circuit comprising at least one transition impedance, as well as a connection to a main conductor.
  • the mobile selector unit is actuated by a control device.
  • the typical example of such an electrical appliance with multiple sockets is a stepped electrical transformer equipped with a tap changer for a charge selector.
  • the invention is not however limited to transformers but can be applied to other electrical devices such as compensation inductors, resistance banks or capacitor banks. These devices can be single-phase or can be designed for several phases. As in the vast majority of cases, the circuits of the selector crew or the sets of switches of the different phases are identical between them and present differences only when special effects are envisaged, the description below is limited to the single-phase case .
  • Step transformers operating with the aid of mobile selector units for on-load tap-changers are well known and described in numerous patents and other prior documents.
  • a portion of a winding, seat of an electromotive force which one wants to add or subtract is short-circuited by one or more transition impedances housed on the moving part and put into service during one or more intermediate positions of this moving part.
  • the different sockets constituting the fixed contacts are electrically connected to the outputs of the adjustment winding, and are arranged, at a sufficient dielectric distance from each other, on the internal face of an insulating cylinder, at the inside which a movable selector assembly is driven in a rotational movement along the axis of the cylinder.
  • the mobile selector assembly is made up of three rows of rollers.
  • the central row consists of several main rollers which ensure the flow of current when the moving part is stopped in front of a fixed contact
  • the end rows consist of a single auxiliary roller used to insert the transition impedances when moving the moving element and allowing switching without interruption of current.
  • these three rows of rollers are each mounted on stirrups driven by a telescopic movement or an oscillating movement with a spring device giving each of these rows of rollers an adequate pressure on the fixed contact.
  • the lateral space requirement of the three rows of rollers of the moving element reduces the dielectric distance relative to the fixed contacts, close to that before which the moving element is stationary and limits the number of fixed contacts over a determined length of circumference.
  • This moving element consists of a central main contact and an 'even number of auxiliary contacts connected, in pairs, to impedances of different values.
  • the crew overflows widely on both sides and greatly reduces the isolation distance. Consequently, in order to restore sufficient isolation distances, it is necessary to increase the distance between the fixed and successive contacts and thus increase the total size of the device.
  • the present invention relates to a movable assembly for temporary contacts according to the preamble of claim 1. It is characterized in that means are provided to allow a translation of the auxiliary rollers in the direction of the main rollers or in the opposite direction according to forces. generated by the displacements of the auxiliary rollers on the tracks of the fixed contact. In a preferred embodiment, it is characterized in that two end stirrups oscillate on either side of their rest position, by an optionally adjustable angle and it makes it possible to remedy these drawbacks. The inclination of the end brackets reduces the lateral dimensions of the moving element at the level of the rollers, consequently, it increases the number of fixed contacts distributed over the same length of circumference and makes it possible to have an adjustment winding. with more intermediate outputs.
  • the contact pressure of the auxiliary rollers on the fixed contact and the return to the rest position are obtained by a device equipped with one or more springs.
  • This particular provision communicates to the auxiliary roller, responsible for cutting the circulation current established from the moment when the two end stirrups are simultaneously in contact with the successive fixed contacts, a high breaking speed by adding to the speed of the moving equipment that which is communicated by the end bracket return device.
  • This additional characteristic reduces the electrical wear of the auxiliary rollers responsible for cutting off the circulation current which in certain cases can be as high as the line current.
  • FIG. 1 representing the mobile assembly at rest, the central stirrup (1) made of a material which is good conductor of electricity is located in the center of the fixed contact (5) and the end stirrups (2), also made of good conductors of electricity are both in their rest position.
  • the whole of this mobile assembly pivots about an axis (6) of a cylinder (7) on which the fixed contact (5) is positioned.
  • an axis (8) held at each end in a slide (9) made of insulating material, supports two main copper rollers (10) and a cutter roller made of copper-tungsten alloy (11) and slides in a buttonhole (12).
  • a coaxial spring (14) of the axis (8) ensures the continuity of the electrical circuit by applying the sides of the main copper rollers (10) against the stirrup (1).
  • FIG 3 is an elevational view of the central bracket (1) stopped on the fixed contact (5).
  • This fixed contact (5) consists of two tracks (30) made of a material that is good conductor of electricity and located on either side of a central track (31) made of material resistant to electric arc.
  • the central track (31) is arranged in a plane recessed with respect to the plane of the tracks (30).
  • the central section (31) is longer than the tracks (30) and ends at each end with an inclined plane (32) which facilitates access to and departure from the cutting roller (11).
  • each track (30) made of a material which is a good conductor of electricity ends at each end by an inclined plane (33) which facilitates access to and departure from the main rollers (10).
  • the main rollers (10) roll on the tracks (30) then on the inclined planes (33).
  • the cutting roller (11) can in turn roll on the track (31) then on the inclined plane (32). In this way, the breaking of the current carried by the fixed contact (5) is carried out at the inclined plane (32) and the cutting roller (11) both made of material resistant to electric arc.
  • FIG 4 showing an exemplary embodiment of an end bracket (2) at rest, the rotation of the bracket (2) is provided by an axis (15).
  • One end of the stirrup (2) supports an axis (20) around which an auxiliary roller (21) made of copper-tungsten alloy pivots, the other end of the stirrup ends with a bar (22) which, in position rest, is aligned with the axis (15) and the spacer (19).
  • the strands (17) and (18) work respectively in the opposite direction in the manner described above.
  • the use of a torsion spring (16) as a calliper return device (2) makes the contact pressure between the auxiliary roller (21) and the fixed contact (5) proportional to the angle, the stirrup (2) deviates from its rest position.
  • a corrugated washer (23) made of a material that is a good conductor of electricity is introduced between the auxiliary roller (21) and each arm of the caliper (2). Current can thus be conveyed from the auxiliary roller (21) to an outlet (24).
  • the angular movement is adjustable by an eccentric device modifying the position of the center of rotation of the bracket considered.
  • This angular movement, for each end bracket (2) is also adjustable by a device modifying the position of at least one end stop of the end bracket (2).
  • diagram 5 A shows the mobile assembly at rest on the fixed contact (5).
  • the bracket (1), supporting the main rollers (10) is in the middle of the fixed contact (5) and carries the line current IL at the tap voltage (29), from the fixed contact (5) to a main conductor (28).
  • the end stirrups (2) supporting the auxiliary rollers (21) are respectively designated by (2G) and (21 G) for the stirrup and the auxiliary roller located to the left of the central stirrup and by (2D) and ( 21 D) for the caliper and the auxiliary roller located to the right of the central caliper.
  • the end brackets (2G and 2D) and the auxiliary rollers (21G and 21 D) are at the potential of the socket (29).
  • the electrical circuit connecting the fixed contact (5) to the main conductor (28) is formed by two parallel branches of unequal resistances.
  • the branch of the end clamp (2G) into which the impedance (26) is inserted does not conduct the current; it is the branch of the central stirrup (1) of practically zero resistance which continues to convey the line current IL from the fixed contact (5) to the main conductor (28).
  • Diagram 5C represents the moving assembly at the moment when the central stirrup (1) has just left the fixed contact (5) by cutting the line current IL, the passage of which is ensured, thereafter, by the branch of the end clamp (2G) through the impedance (26).
  • Diagram 5D shows the moving assembly when the auxiliary roller (21 D) of the end bracket (2D) approaches the fixed contact (25) while the roller.
  • auxiliary (21G) of the end bracket (2G) has not yet left the fixed contact '(5).
  • the IL line current. reaching the main conductor (28) is practically driven in half by the branch comprising the auxiliary roller (21G), the end clamp (2G) and the impedance (26), the other half of line current flows to through the branch comprising the auxiliary roller (21 D), the end bracket (2D) and the impedance (27).
