Definitions

  • the present invention relates to a high-voltage electrical disconnection (or connection) disconnector device according to the preamble of claim 1.
  • the disconnector In closed mode, the disconnector thus makes it possible to pass a high load current (above 1500 amperes) between, for example, electrical units commonly referred to as systems. of bus.
  • a mechanism for separating the male and female connectors is provided in order to obtain a break in said current, this cutoff giving rise to an electric arc formation that must be effectively resorbed in order, for example, to prevent any inadvertent reignition.
  • An object of the present invention is to provide a disconnecting disconnector device or high-voltage electrical connection for increasing the disconnector disconnection performance, particularly for the case where higher values of BTV transfer voltages and currents, BTC are required.
  • a first of the blocks is movable between and relatively to the male end of the male contactor and the second block ensuring contact with the second set of contactors-spring during the disconnection mode, it is possible to form during this said mode two interstices at the longitudinal ends of the movable block, that is to say vis-à-vis the male end of the male contactor and a face of the second block.
  • the cutoff arc formed during the disconnection mode is subdivided into two arcs, each of which is located in one of the two interstices formed.
  • the arcs being formed in series, their tensions add up, which thus makes it possible to satisfy GIS post conditions at disconnector of higher values of voltage or transfer current BTV, BTC.
  • the first set of contactors-spring is disconnected from the male contactor (hence a minimized wear of the first set of contactors-spring), while through the second set of contactors-spring and by means of a maintenance of contact between the male contactor and the conductor comprising the two blocks, the current initially passing during the closed mode in parallel through each of the sets of contactor-spring is not suddenly cut, but is redistributed in a very short time to one of said passages in parallel, which thus makes it possible not to generate arc cutoff at the beginning of disconnection as usually known.
  • a set of subclaims also has advantages of the invention.
  • the first and second sets of spring contactors (3, 5) are respectively disposed on the first and second internal circumferences of the female contactor, the said circumferences being distinct because they are juxtaposed longitudinally in the recess of the female contactor in which the closed the male end (or pin) of the male contactor is housed.
  • the disconnecting device provides a thrust arrangement (4) which exerts a force on the conductor comprising the two blocks (6, 7) towards the longitudinal end (pin "male") of the male contactor (1), ensuring their contact in the closed disconnector.
  • the two blocks (6, 7) are electrically conductive and arranged in series in the longitudinal direction, said blocks being dissociable in said direction by a spacer means - such as here an elastic retaining arrangement (8, 9, 9 ') - in the next disconnection mode of the disconnector.
  • Figure 2 presents the disconnector device according to figure 1 at the beginning of the disconnection mode, while the male contactor (1) has initiated its longitudinal withdrawal to withdraw from the first set of spring contactors (3).
  • the first series connection of the contactor male (1), the first set of contactors-spring (3), the female contactor (2) is open, so that the first current passage (I1) is blocked.
  • the thrust arrangement (4) always exerts a force on the conductor comprising the two blocks (6, 7) towards the longitudinal end (pin "male") of the male contactor (1), thus ensuring their contacts, so that the second current passage (I2) is maintained through the second set of spring contactors (5). It is thus advantageously avoided to generate a first and only breaking arc between the contactors (1, 2) at the beginning of disconnection, such as for usual disconnection configurations between male and female contactors.
  • Figure 3 presents the disconnector device according to Figures 1 and 2 at the end of the disconnection mode, whereas, the thrust arrangement (4) always exerts a force on the conductor comprising the two "first and second" blocks (6, 7) towards the longitudinal end of the male contactor (1) . Then, knowing that the male contactor (1) continues its withdrawal stroke of the female contactor, it finally appears a gap between the end of the male contactor (1) and the second block (6) closest to said male contactor (1). ), said block having a limited stroke. It is then that a dissociation of the two blocks (6, 7) can be initiated. Also, said dissociable blocks reach their position dissociated along said direction by a spacing means in disconnector disconnection mode.
  • the spacing means is at most simple an elastic retaining arrangement (8, 9, 9 ') interacting on at least one longitudinal end of the conductor comprising the two blocks (6, 7) arranged in series and to dissociate longitudinally.
  • the purpose of this restraint is to dissociate the said blocks (6, 7), while the first block (6) closest to the male contactor (1) also dissociates itself from the male contactor still set back from the female contactor .
  • the resilient retaining arrangement may thus comprise an axis (9) (electrically insulating) with a sectional stop (9 ') coupled via tensors (8) to the second most movable block (7).
  • the first block (6) being arranged fixed on the axis (9) farthest from the stop (9'), so that said second block (7) and the tensors (8) exert a longitudinal return or withdrawal of the stop (9 ') since, in disconnection mode, the other first block (6) is separated from the male end of the male connector (1).
  • the resilient retaining arrangement comprises a sectional abutment axis (9 ') coupled via tensors (8) to the second block (7) closest to said abutment (9), the first block (6) being willing on the axis (9) farthest from the stop (9 '), the axis (9) with sectional stop (9') coupled to tensors (8) exerting a longitudinal force on the block (6) in order to moving said block (6) with the axis (9) and away from the other block (7) on the axis.
  • two interstices are formed in series (between the elements 1 and 6 as well as between the elements 6 and 7), where break arcs (10, 11) are created in series as referred to in FIG. 'invention.
  • the insulating gas such as SF6 is then housed in the interstices to blow the arcs and realize their respective cut.
  • the spacing means may comprise magnets arranged between longitudinal ends of the blocks (6, 7) and having identical magnetic poles exerting a repulsive force between said blocks.
  • the spacer means may comprise electrically insulating compressible elements arranged in notches of the longitudinal ends of the blocks (6, 7) and exerting a repulsive force between said blocks.
  • Figure 4 finally presents the device according to one of Figures 1 to 3 in open mode.
  • the cutoff arches (10, 11) in series were smothered by SF6 gas in the interstices.
  • the device according to the invention as shown in one of the figures is adapted to the requirements of the IEC 62271-102 standard and in particular to a related revision CD 17A / 1067 / CD, according to a version 02/201.
  • the high-voltage electrical disconnection disconnector device presented in the scope of the invention is also analogically adapted to allow electrical connection of the male and female contactors, for example by considering connection modes defined by the preceding Figures 1 to 4 successively taken in their reverse order.
