Definitions

  • the invention relates to a switch panel for an outdoor switchgear.
  • An outdoor switchgear is cheaper and easier to maintain than a corresponding gas-insulated switchgear.
  • sulfur hexafluoride which is known to be a very strong greenhouse gas, is also often used as an insulating and/or quenching gas.
  • outdoor switchgear is therefore also more environmentally friendly.
  • the invention is based on the object of specifying an improved control panel for an outdoor switchgear which is particularly suitable for reducing the space requirement of the outdoor switchgear.
  • the object is achieved according to the invention by a switch panel with the features of claim 1 and an outdoor switchgear with the features of claim 13 .
  • a switch panel comprises a circuit breaker with a housing and an interrupter unit arranged in the housing, outdoor bushings through which an electrical conductor is guided from the housing to a contact element arranged on the outdoor bushing, a carrier on which the housing is arranged, and a pivoting mechanism by which the contact elements are pivotable between two end positions.
  • the control panel combines the functions of a circuit breaker and a circuit breaker.
  • the circuit breaker is used in particular for the rapid switching of high overload currents and short-circuit currents which flow via a current path which runs through the switching panel between the contact elements arranged on the outdoor bushings.
  • the circuit breaker can, in particular, be gas-insulated with a gas-tight housing and thus have a compact design.
  • the isolating switch function is realized by the pivoting of the contact elements, with which the electrical connections of the contact elements to the corresponding mating contacts can be visibly separated. This makes the panel particularly suitable for an outdoor switchgear as a combined circuit breaker and disconnector, which requires less space than a separate version of a circuit breaker and a disconnector .
  • An embodiment of the control panel according to the invention provides that the housing is mounted on the carrier so that it can rotate about a rotation axis and can be rotated about the rotation axis, for example by 90 degrees, by the pivoting mechanism.
  • the housing is mounted on the carrier so that it can rotate about a rotation axis and can be rotated about the rotation axis, for example by 90 degrees, by the pivoting mechanism.
  • each outdoor bushing can be pivoted about a pivot axis, for example by 90 degrees, using the pivoting mechanism.
  • the outdoor bushings are not rigidly connected to the circuit-breaker housing, but can be pivoted relative to the housing .
  • each outdoor bushing is connected to the housing by a flange that can be rotated about the pivot axis.
  • the pivoting mechanism has a drive for pivoting the contact elements.
  • the drive is designed as a belt drive with a belt that can be driven by a motor.
  • the support is adjustable in height, in particular by a drive.
  • the carrier has a scissor mechanism for height adjustment, which is arranged on a frame, for example.
  • the height adjustability of the carrier makes it possible to lower the circuit breaker and the outdoor bushings with the contact elements arranged thereon, for example down to ground level. As a result, these components of the panel can be easily maintained, repaired or replaced without the need for a crane, for example. If the panel is arranged in an outdoor switchgear, this can be achieved, for example, that maintenance, repairs or replacing these components, it is not necessary to switch off adjacent parts of the plant, so that these parts of the plant can continue to be operated.
  • a further embodiment of the switching panel according to the invention provides at least one support which is set up to support a counter-contact for a contact element.
  • the counter-contact can be held in a fixed position, which is advantageous, for example, when the counter-contact is connected to a conductor cable.
  • An outdoor switchgear according to the invention has a switch panel according to the invention, the switch panel being arranged in such a way that in a first end position of the contact elements of the switch panel each contact element contacts an electrical counter-contact and in the second end position of the contact elements the contact elements of the mating contacts are separated.
  • An outdoor switchgear according to the invention advantageously uses the aforementioned space-saving double function of a switch panel according to the invention as a circuit breaker and disconnector.
  • a mating contact contacted by a contact element is a busbar contact of a busbar in the outdoor switchgear
  • the switch panel is arranged in such a way that a straight line running through two contact elements is in the first End position of the contact elements forms an angle different from zero and 90 degrees with a longitudinal axis of the busbar.
  • FIG. 1 shows a perspective view of an exemplary embodiment of a switching panel in a first position
  • FIG. 2 shows a perspective view of the switch panel shown in FIG. 1 in a second position
  • FIG. 3 shows a perspective view of the switch panel shown in FIG. 1 in a third position
  • FIG. 4 shows a plan view of an exemplary embodiment of an outdoor switchgear.
  • FIGS. 1 to 3 show perspective representations of an exemplary embodiment of a control panel 1 according to the invention in different positions.
  • the switch panel 1 comprises a circuit breaker 3 with a housing 5 and an interrupter unit arranged in the housing 5, two outdoor bushings 7, 9, through which an electrical conductor is routed from the housing 5 to one arranged on the outdoor bushing 7, 9 Contact element 11, 13 is guided, a carrier 15 on which the housing 5 is arranged, a pivoting mechanism 17, through which the contact elements 11, 13 can be pivoted between two end positions, and a supporter 19, which is used to support a first Mating contact 21 for a first contact element 11 is set up.
  • the circuit breaker 3 of this exemplary embodiment is designed in what is known as the dead-tank design, with the housing 5 being made of metal and being grounded when the circuit breaker 3 is in operation. Furthermore, the housing 5 is designed to be gas-tight and, when the circuit breaker 3 is in operation, is filled with a pressurized gas, for example with an insulating gas such as sulfur hexafluoride or with air.
  • the outdoor bushings 7, 9 of this exemplary embodiment extend in a V-shape, i.e. at an angle other than zero degrees to one another, away from the housing 5 (in other exemplary embodiments, the outdoor bushings 7, 9 can be arranged parallel or perpendicular to one another) .
  • One of the contact elements 11 , 13 is arranged on an end of each outdoor bushing 7 , 9 facing away from the housing 5 .
  • the contact elements 11, 13 of this exemplary embodiment are each designed like plates.
  • the housing 5 is rotatably mounted on the carrier 15 about an axis of rotation A and can be rotated by the pivoting mechanism 17 about the axis of rotation A by 90 degrees.
  • the swivel mechanism 17 has a belt drive with a belt 25 that can be driven by a motor (not shown).
  • the carrier 15 comprises a scissor mechanism 27, through which it can be adjusted in height, and a frame 29, on which the scissor mechanism 27 is arranged and which is made of a metal or an alloy, for example steel.
  • a drive cabinet 31 is arranged on the framework 29 , in which a drive for the scissor mechanism 27 is arranged.
  • FIG. 1 shows the switch panel 1 in a first position of the circuit breaker 3 and the outdoor bushings 7, 9 with the contact elements 11, 13 arranged thereon. In this position, the first contact element 11 electrically contacts the first counter-contact 21 and the second contact element 13 contacts a second counter-contact 22 .
  • a current path runs between the two mating contacts 21 , 22 through the panel 1 which can be opened and closed by the interrupter unit of the circuit breaker 3 .
  • the circuit breaker 3 is used in particular for switching high overload currents and short-circuit currents that flow via this current path.
  • the first mating contact 21 is, for example, a field outgoing contact to a conductor cable 41 of an outdoor switchgear 40
  • the second mating contact 22 is, for example, a busbar contact of a busbar 44 of the outdoor switchgear 40 (see FIG. 4).
  • the mating contacts 21, 22 each have a slot into which the respective contact element 11, 13 is inserted in the position shown in FIG.
  • the support 19 holds the first mating contact 21 in a fixed position.
  • FIG. 2 shows the switch panel 1 in a second position of the circuit breaker 3 and the outdoor bushings 7, 9 with the contact elements 11, 13 arranged thereon.
  • the housing 5 is rotated by the pivoting mechanism 17 by 90 degrees about the axis of rotation A compared to the position shown in FIG.
  • the two contact elements 11, 13 are pivoted from their first end position shown in FIG. 1 about the axis of rotation A into a second end position shown in FIG. 2, in which they are separated from the mating contacts 21, 22.
  • the panel 1 Due to the pivotability of the contact elements 11, 13, the panel 1 has a circuit breaker function, with which the current path between the mating contacts 21, 22 is visibly separated by pivoting the contact elements 11, 13 into the second end position.
  • the contact elements 11 , 13 are separated from the counter-contacts 21 , 22 when the switching panel 1 is in no-load operation.
  • FIG. 3 shows the switch panel 1 in a third position of the circuit breaker 3 and the outdoor bushings 7, 9 with the contact elements 11, 13 arranged thereon.
  • the circuit breaker 3 and the outdoor bushings 7, 9 with the contact elements 11, 13 arranged thereon are lowered by the scissor mechanism 27 of the carrier 15 to a safety distance from the mating contacts 21, 22 compared to the position shown in FIG .
  • maintenance or repair work can be carried out on the circuit breaker 3, the outdoor bushings 7, 9 and/or the contact elements 11, 13 arranged thereon.
  • FIG. 3 indicates that these components can be transported away, for example, with a forklift truck on fork carriers 33 of the forklift truck.
  • the exemplary embodiment of a switching panel 1 shown in FIGS. 1 to 3 can be modified in various ways to form other exemplary embodiments.
  • the contact elements 11 , 13 can be designed in a manner other than plate-like.
  • the pivoting mechanism 17 can have another drive for rotating the housing 5 about the axis of rotation A instead of a belt drive.
  • the pivot mechanism 17 can be set up to pivot the outdoor bushings 7 , 9 about a pivot axis relative to the housing 5 instead of rotating the housing 5 about the axis of rotation A.
  • the outdoor bushings 7 , 9 are connected to the housing 5 for this purpose by a flange that can be rotated about the pivot axis.
  • FIG. 4 shows a plan view of an exemplary embodiment of an outdoor switchgear assembly 40 according to the invention.
  • the outdoor switchgear 40 has switch panels 1 , conductor cables 41 and busbars 44 .
  • the conductor cables 41 run parallel to one another and perpendicular to the busbars 44 .
  • Each panel 1 is designed like the panel 1 described with reference to FIGS. 1 to 3 and assigned to a conductor cable 41 and a busbar 44 .
  • Each panel 1 is arranged in such a way that, in the position shown in FIG. and its second contact element 13 makes electrical contact with a counter-contact 22, which is a busbar contact of the busbar 44 assigned to the panel 1.
  • a straight line L running through both contact elements 11 , 13 forms an angle a different from zero and 90 degrees (approximately 45 degrees in this example) with a longitudinal axis of the busbar 44 assigned to the switching panel 1 .
  • This oblique arrangement of the switch panels 1 relative to the busbars 44 and conductor cables 41 allows the switch panels 1 to be arranged under the busbars 44 in a space-saving manner. Since the panels 1 each have a disconnector function next to the circuit breaker 3, no additional circuit breaker is required for a panel 1. This also eliminates the space requirement for these isolating switches. Overall, the outdoor switchgear 40 can thus be built in a much more space-saving manner than a conventional outdoor switchgear. For example, around 16 percent of the space required can be saved compared to a conventional outdoor switchgear .
