Definitions

  • the invention relates to a pressurized gas-insulated disconnector module with an electrically conductive housing and with a main axis, along each of which a first and second electrical conductor adjoining an isolating switching path extends.
  • Such a circuit breaker module is known, for example, from US Pat. No. 6,538,224 B2.
  • an interrupter unit of a circuit breaker is arranged within an earthed encapsulation housing.
  • Flanges are arranged on the encapsulation housing, through which electrical conductors are made for contacting the interrupter unit.
  • a disconnector module is flanged to the flanges.
  • the electrical conductors supplied can be electrically isolated from the interrupter unit by means of the disconnector modules.
  • the isolating switch modules are delimited by means of bulkhead isolators from adjacent pressurized gas-insulated areas of the encapsulation housing of the circuit breaker or from adjoining open air bushings. Since the outdoor bushings are no longer flanged directly to the encapsulation housing, the position of the outdoor connections changes by the length of the isolator switch modules.
  • a circuit breaker equipped with such disconnector modules can no longer be used, for example, in standardized switch panels.
  • the present invention is based on the object of designing a pressure-gas-insulated disconnector module of the type mentioned at the outset such that it has a short overall length.
  • the object is achieved according to the invention in a pressurized gas-insulated disconnector module of the type mentioned at the outset in that the first phase conductor penetrates a first flange of the disconnector switch housing and the second phase conductor penetrates a second flange of the disconnector switch housing.
  • a tubular electrode is connected to the housing of the isolating switch module and concentrically surrounds the first phase conductor and is arranged radially on the inside of the first flange and projects beyond it.
  • the flange surfaces of the first flange are dielectrically shielded by the tubular electrode. This makes it possible to arrange the housing of the isolating switch module in a small volume directly around the isolating circuit of the isolating switch. This shortens the insulating distances that determine the size.
  • a further advantageous embodiment can provide that the second flange, which is arranged coaxially to the first flange at the opposite end of the housing, has on its outside a receiving device onto which an annular converter can be placed.
  • the coaxial arrangement of the first and second flange creates an elongated shape of the disconnector module. All the devices necessary for the construction of the isolating switch module can extend along the main axis. In addition to the flange function of the second flange, this can also be used have on the outside also a receiving device for an annular transducer. This enables the disconnector module to be completed as a sub-assembly.
  • the second flange is arranged at the end of a tubular connecting piece, which at least partially carries the transducer.
  • the overall height of the isolating switch module can be reduced by combining the second flange with a tubular connecting piece.
  • the converters which are alternatively attached to intermediate housings or to a counter flange, are now assigned to the isolating switch module. This can reduce the number of flange connections required. This reduction enables the overall length of the disconnector module to be reduced.
  • first and the second flange are annular and the first flange has a larger circumference than the second flange.
  • annular transducer can be easily pushed onto the second flange. Its outer contour corresponds approximately to the contour of the first flange. This creates an almost cylindrical contour from the outside in the overall structure of the disconnector module. Individual projecting assemblies are thus avoided. At the same time, sufficient space is made available in the area of the first flange in order to shape the tubular electrode in a suitable manner.
  • a further advantageous embodiment can provide that the electrode is carried by the housing, in particular cast on.
  • the housing In order to achieve sufficient pressure resistance of the housing, it must be made of a mechanically stable material, for example aluminum.
  • the housing forms, as it were, a scaffold for all of the assemblies attached to or installed in it, such as the isolating circuit and the converter. Mechanical forces are introduced into the housing structure via the first or second flange. Casting the electrode onto the housing allows particularly effective manufacturing processes for producing the housing. For example, it can be manufactured as a one-piece cast body. In this way, slender configurations of the housing can also be produced.
  • a further advantageous embodiment can provide that one of the phase conductors can be earthed inside the housing by means of an earthing switch.
  • a compressed gas is applied to the interior of the housing. Therefore, this room is not mechanically accessible from the outside. If an earthing switch is operated incorrectly, arcing faults occur which could affect the health of the operating personnel. An arcing fault is hardly possible from inside the housing. In this way, in particular in the case of manually operated earthing switches, a hazard to the operating personnel can be virtually ruled out.
  • the use of a plurality of earthing switches can also be provided, for example to earth a first and a second phase conductor.
  • outdoor bushings are provided for connecting electrical lines to the circuit breaker interrupter unit.
  • the conventional structure of the known isolating switch module forces the isolating switch module to be inserted between an outdoor bushing and a connecting flange of the encapsulating housing of the circuit breaker.
  • the object is achieved according to the invention in a bushing arrangement with a circuit breaker with a circuit breaker which is arranged within an electrically conductive housing in a pressure gas-insulated manner in that an electrically insulating union flange flanged to the housing is penetrated in the manner of an open-air bushing by a first phase conductor passed through the union , which is connected at one end to a switch contact of the isolating switching path, the housing and the union surrounding a common gas space.
  • the common gas space makes it possible to dispense with the use of bulkhead insulators.
  • These bulkhead isolators increase the overall volume of a bushing arrangement with isolating switch by the overall height of the necessary flanges or the insulating bulkheads.
  • a connection of a switching contact of the isolating switching path with the first phase conductor enables sufficient mutual mechanical stabilization of the isolating switching path and the first phase conductor.
  • the first phase conductor can, for example, be held on the insulating sleeve in the area of its passage through the wall of the sleeve.
  • the common gas space also makes it possible for the modules to share sections of the electrically conductive housing. Strict separation and division into individual gas spaces would make such flexible use of space in the housing difficult.
  • the first phase conductor is supported on the housing by means of a column support.
  • the column support can be arranged very flexibly inside the housing. It can be provided that the column support is arranged directly on the first phase conductor, or it can also be advantageously provided that the first phase conductor is supported via a switch contact of the disconnector.
  • the gas space extends into a tubular socket of the housing, around which an annular transducer is arranged.
  • an electrode extends coaxially with the first phase conductor and the electrode shields the connection area of the insulating union with the housing.
  • the use of the electrode makes it possible to shorten the transition area from the grounded housing to the insulating union.
  • the electrical fields are influenced by the electrode in such a way that the connection area of the electrically insulating sleeve and the housing of the first flange are not exposed to any impermissible electrical loads.
