Definitions

  • the invention relates to an outdoor switching device and a method for switching high voltages of several phases, with at least two interrupter units, each of which is assigned to a different phase.
  • An outdoor switching device for high voltages in particular for switching voltages of up to 1200 kV and/or currents of up to several hundred amperes, is known, for example, from DE 196 08 285 A1 , DE 19 95 069 U , GB 1 013 971 A , DE 10 2004 042310 A1 and DE 10 2016 202853 A1 known.
  • the outdoor switching device comprises an interrupter unit for one pole, which is arranged in an insulating housing. Overhead lines can be connected via two electrical connections and a current path between the overhead lines can be switched via the interrupter unit. The current path between the two connections can be closed and/or opened via the interrupter unit for one pole, i.e. one phase of current/voltage.
  • the interrupter unit in the insulating housing is arranged coaxially on an insulating housing part and forms a pole column on a support frame.
  • the pole column stands on the ground, e.g. a concrete foundation, pointing essentially vertically upwards, i.e. the longitudinal axis of the pole column forms a right angle to the horizontal plane of the ground.
  • Each pole column with associated interrupter unit is designed to switch one phase in a current path between two connections for, for example, overhead lines, electrical consumers and/or power generators.
  • Three separate pole columns arranged next to each other are designed to switch three to switch different phases simultaneously and/or separately from one another at different times.
  • the arrangement of separate pole columns for switching different phases is complex, costly and space-intensive, and requires several separate foundations and several similar elements such as support frames, drives and/or insulating housing parts next to one another.
  • the object of the present invention is to provide an outdoor switching device and a method for switching high voltages of several phases, which avoid the problems described above.
  • the object is to provide a simple, compact and cost-effective outdoor switching device for switching high voltages of several phases, which requires little space in the open field and is designed to switch several phases with a common drive.
  • an outdoor switching device for switching high voltages of several phases with the features according to claim 1 and/or with a method for switching high voltages of several phases with the above-described outdoor switching device according to claim 12.
  • Advantageous embodiments of the outdoor switching device according to the invention for switching high voltages of several phases and of the method for switching high voltages of several phases with the above-described outdoor switching device are specified in the subclaims. Subject matters of the main claims can be combined with one another and with features of subclaims, as well as features of the subclaims with one another.
  • the interrupter units are arranged on a common carrier.
  • the arrangement of the interrupter units for switching different phases on a support results in a simple, compact and cost-effective outdoor switching device for switching high voltages of several phases, which requires little space in the open field and is designed to switch several phases with a common drive.
  • outdoor switching devices with several parallel pole columns which are each designed separately for one phase and arranged next to each other independently of each other, supports and the associated material and costs are saved.
  • the at least two interrupter units are arranged on different longitudinal axes, in particular on longitudinal axes that are not parallel. This makes it possible to achieve good insulation of the individual phases from one another or of the electrical connections of the interrupter units of different phases from one another, with a compact structure.
  • the different longitudinal axes can be arranged at an angle ⁇ that is not equal to zero.
  • an angle ⁇ in the range of 90 degrees can result in a maximum distance and thus good electrical insulation of electrical connections of the interrupter units of different phases from each other.
  • an angle ⁇ in the range of 60 degrees can result in a maximum distance and thus good electrical insulation of electrical connections of the interrupter units of different phases from each other.
  • the different longitudinal axes intersect at one point when viewed from above.
  • the electrical connections of the interrupter units of different phases from the point of intersection, in particular the external connections of the outdoor switchgear to e.g. power lines, power generators and/or consumers, a good electrical Isolation of electrical connections from one another, in particular different phases and/or the same phase with the current path open.
  • the at least two interrupter units are arranged in different planes, essentially parallel to the substrate and at different distances from the substrate. This means that interrupter units for different phases on crossing axes that do not intersect can be electrically well insulated from one another. Crossing axes that do not intersect arise from longitudinal axes that intersect when viewed perpendicular to the axes in a top view and, for example, run parallel when viewed perpendicular to the top view in a side view.
  • the interrupter units can comprise vacuum tubes and/or gas-filled circuit breakers, in particular with rated and arcing contacts. This makes it possible to achieve high switching voltages of up to 1200 kV and higher per phase and switch high switching currents of up to several hundred amperes. Circuit breakers, in particular with rated and arcing contacts, can comprise switching gases, e.g. SF 6 and/or clean air.
  • the interrupter units can be compact and/or cost-effectively encased directly with an insulator, in particular ceramic and/or silicone, and/or arranged in insulating housings which comprise an insulator.
  • Two or more interrupter units per phase can be included, in particular connected in series and/or arranged on a common longitudinal axis per phase. This allows high switching voltages to be achieved with inexpensive, in particular standardized interrupter units. For example, a series connection of vacuum tubes with switching voltages of up to 35 kV each can result in an outdoor switching device with switching voltages of several hundred kV per phase. Parallel connection of two or more interrupter units per phase can enable analogously high switching currents, especially in the range of several hundred amperes.
  • the common support can be designed in the form of a column, in particular in the form of exactly one column.
  • the support in particular designed in the form of a column, can be arranged essentially vertically upright on the ground. This assumes a horizontally flat ground in one plane, in which, for example, a foundation made of concrete is formed for firmly anchoring the column on the ground.
