Definitions

  • the invention relates to the field of metal-encapsulated gas-insulated switchgear (GIS), in particular the gas-insulated high-voltage switchgear and relates to a gas-insulated switchgear module.
  • GIS metal-encapsulated gas-insulated switchgear
  • a cubicle is generally understood here as a field of a switchgear and can e.g. also designate a departure field.
  • GISs whose switchgears have a single-phase encapsulated guide of the primary conductors are fundamentally distinguished from GIS, whose switchgear panels have a three-phase encapsulated guide of the primary conductors.
  • the type of encapsulation (single or three-phase) of the nominal conductor for guiding the primary currents can be mainly due to the desired nominal voltage: single-phase encapsulated panels (panels) or switchgear modules allow a significantly higher rated voltage at a comparable cost. Furthermore, the type of encapsulation has fundamental effects on the layout of the fields and on the design and arrangement of the modular functional groups.
  • a representative of a housing for a three-phase encapsulated guidance of the primary conductors is described, for example, in WO 2008/022893 A1.
  • the primary conductors are arranged in a triangular configuration for three-phase encapsulated leads.
  • Three-phase encapsulated lines have the disadvantage that in this case a large internal volume is created, which is to be filled with insulating gas. Furthermore have single phase encapsulated switchgear modules compared to traditional three-phase encapsulated switchgear modules a better behavior in case of a ground fault.
  • busbar In order to realize a gas-insulated substation, typically at least two fields are connected on the input side or output side to a so-called busbar.
  • busbar includes both single- and triple-encapsulated guided Primärleitersch rails. For this reason, GIS busbars with single-phase busbar routing are also differentiated from GIS with three-phase busbars.
  • the object of the invention is therefore to avoid at least a few of the disadvantages of the generic switchgear, and a multi-phase encapsulated
  • the idea of the invention now consists of improving or increasing the versatility of a GIS switchgear panel and thus of power density per unit volume of a GIS switch panel by merging the first type of GIS and the second type of GIS into a new, third type of GIS ,
  • This third genus of GIS forms a hybrid of the first and second asset classes.
  • This hybrid combines as many advantages of both genera and In the busbar housing, a connection topography in the space to a busbar of an adjacent switching field, as is known from single-phase encapsulated busbars, is possible with an arrangement of the busbar conductors in the busbar housing which is encapsulated in an eh / three-phase manner.
  • a switchgear module with a housing for receiving an insulating gas and at least three arranged in the housing gas-insulated nominal conductors of at least three different phases, the housing having a first connection area at least three first connection openings of the nominal conductors, and a second connection region having at least three second connection openings of the nominal conductors, wherein the at least three first connection openings and the at least three second connection openings are interconnected by a continuous gas space, wherein in each case a nominal conductor from a first connection opening to a second connection opening extends.
  • a first distance from the nominal conductor to an inner wall of the housing is less than every other distance through the contiguous gas space from the nominal conductor to each other of the nominal conductors of another phase.
  • a nominal conductor serves to carry a nominal load during operation.
  • an arc occurs, for example between a first phase conductor (for example R) and its corresponding, metal-enclosed housing by the arc with respect to the Conductor axis forms radially to the housing wall.
  • the short circuit does not spread to the other phase conductors (such as S and T) but remains single-phase until a protective shutdown occurs or the housing wall fails.
  • only one phase is affected by the short circuit, while the other two phases continue to be available for power transmission, depending on the operating concept.
  • the new, third genus according to the invention is a hybrid form of the first and the second genus.
  • the technical effect of the hybrid form lies in the fact that the gas-insulated switchgear, or its busbar section, in the case of an arcing fault, is for the most part like a single-phase encapsulated GIS of the first
  • Species behaves, so in the case of a fault arc rather leads to a ground fault, as to a more energetic, three-phase arc, without having to forego the benefits of a three-phase encapsulated G IS.
  • Such advantages form, for example, a common filling and emptying device for the insulating gas, a common pressure relief valve (for example, a bursting device), a common gas pressure monitoring, a common partial discharge detection and much more, which allow a particularly economical embodiment of the inventive hybrid solution.
  • each nominal conductor is arranged in the busbar housing in a first distance to an inner surface of the housing.
  • the fourth distance relative to the length of the nominal conductor is in most cases smaller than a second distance in which the nominal conductors of the same switchgear module are arranged away from one another. This promotes the formation of a fault arc leading to ground fault instead of a three-phase arc in the event of a short circuit.
  • the distance between the nominal conductor in the predominant longitudinal section and a respective section of an inner wall of the housing can always be smaller than the distance of the nominal conductor from a nominal conductor of another phase. For example, a first nominal conductor of the phase R and a second nominal conductor of a phase S or T.

  • the longitudinal section or the longitudinal direction may follow a curvature of the nominal conductors.
  • the distance to the inner wall of the gas space is in embodiments, in particular in the radial direction, i. measured perpendicular to the longitudinal direction of the nominal conductor. For example, in an embodiment terminating in the housing, the distance may also be measured longitudinally from a tip of the nominal conductor.
  • the nominal signal between a first connection opening and a second connection opening may also comprise switches, which temporarily interrupt an electrical connection between the one first connection opening and a second connection opening.
  • first busbar conductor / nominal conductor or second busbar conductor / nominal conductor per phase is mentioned in advance, this should not be interpreted to mean that this only applies to a single phase (for example R), but that this also applies analogously for the other phases (for example S and T) of the same switchgear module applies.

  • the retracted housing shape and also the openings have the advantage that the gas space 30 can be kept as small as possible, so that as little insulating gas volume has to be provided. Since many insulating gases such as SF6 have unfavorable environmental properties and are also costly, this is particularly desirable.

Abstract

La demande concerne un module (10a) pour installation de commutation, doté d'un boîtier (11a) qui reprend un gaz isolant et au moins trois conducteurs nominaux (14a, 14b, 14c) disposés dans le boîtier en étant isolés par gaz, pour au moins trois phases différentes, le boîtier comprenant une première partie de raccordement (15) qui présente au moins trois premières ouvertures de raccordement (16a, 16b, 16c) pour les conducteurs nominaux et une deuxième partie de raccordement (17) qui présente au moins trois deuxièmes ouvertures de raccordement (34a, 34b, 34c) pour les conducteurs nominaux, lesdites au moins trois premières ouvertures de raccordement et lesdites au moins trois deuxièmes ouvertures de raccordement étant reliées entre elles par un espace continu (30) de gaz, un conducteur nominal s'étendant à chaque fois entre une première ouverture de raccordement et une deuxième ouverture de raccordement. Pour une partie principale (35a, 35b, 35c) de la longueur de chaque conducteur nominal, une première distance (36) entre le conducteur nominal et la paroi intérieure (37) du boîtier (11a) est inférieure à chaque deuxième distance (38a, 38b) entre le conducteur nominal et chacun des autres conducteurs nominaux d'une autre phase dans l'espace continu de gaz.
