Definitions
- the invention relates to a high-voltage outdoor bushing arrangement with an electrically insulating cover and an isolating switch module having an electrically conductive housing, wherein a phase conductor that can be interrupted by a separating section into a first section and a second section extends along an axis through the bushing arrangement extends.
- Such a high-voltage outdoor bushing arrangement is known, for example, from US Pat. No. 6,538,224 B2.
- the arrangement there has a disconnector module with a separate gas space.
- the isolating switching path is aligned along the phase conductor, which can be interrupted in two sections.
- a section of the phase conductor can be grounded by means of an earthing switch.
- This design allows the disconnector module to be inserted into flange connections.
- a conventional disconnector arrangement must be used. As a result, the isolating switch module has a larger volume.
- the present invention is based on the object of specifying a high-voltage outdoor bushing arrangement which has a compact disconnector module and a compact overall volume.
- a switching element or a link has a Nes multi-part contact piece is movable obliquely to the axis.
- the space inside the electrically conductive housing is better utilized. Due to the inclination, the cross-section of the housing determined by the flange openings is better utilized, so that the length in the direction of the axis can be reduced. On the one hand, this shortens the electrically conductive housing, and on the other hand the overall length of the high-voltage outdoor bushing is reduced. Alternatively, if the previous housing size is retained, additional space is available inside, for example to arrange further components within the housing.
- At least one of the sections can be grounded by means of an earthing switch arranged within the electrically conductive housing by continuing a further movement of the switching element.
- the space gained by the inclination of the movement path of the contact piece can, for example, be used advantageously to arrange an earthing switch.
- This earthing switch can be designed as a combination with the isolating switch in order to further minimize the installation space required. It is particularly advantageous if the movable contact piece of the isolating switching path and a movable contact piece of the earthing switch are moved by a common drive.
- the contact piece moves along an oblique path and is designed in the form of a bolt.
- the bolt has contact areas at each of its two ends, with one end facing Switching the switching path and the other end can be used to switch the earthing switch.
- a link-like design of the contact piece also makes it possible, for example, to move on curved tracks.
- the movable switching element is driven via a shaft which passes through the essentially cylindrical housing.
- a substantially cylindrical shape of the housing allows a flexible arrangement of the shaft for driving the movable contact.
- the axis of rotation of the shaft can for example be arranged radially to the axis. Alternatively, it can also be provided that the axis lies skew to the axis of rotation of the shaft.
- the contact piece is designed as a knife contact.
- Disconnectors are intended to create safe isolating paths in a phase conductor. As such, the contact systems of isolating switches are only exposed to a minimal load from switching arcs, since the isolating switches are switched in the de-energized state.
- Knife contacts represent an inexpensive variant for forming a switch contact. A particularly simple embodiment is that To move knife contacts on a swivel path and to insert them into slot-shaped counter contacts.
- the contact piece is pin-shaped.
- pin-shaped contacts can only be produced with increased effort.
- arcing may also occur at isolating switch contacts, for example due to the appearance of charge.
- Pin-shaped contacts are more resistant to arcing stress.
- the isolating switching path is held in the housing via column supports.
- Holding the isolating switching path via support insulators enables the isolating switching path to be arranged very flexibly within the encapsulation housing. Furthermore, the support insulators allow a generous flushing and flow of an insulating gas through the encapsulation housing.
- post insulators for example, the use of bulkhead insulators can be dispensed with. If sections to be partitioned off are dispensed with, the volume of insulating gas available within a gas space is increased. This improves cooling of the contact areas of the disconnector.
- the contact piece can be moved on a curved path.
- a curved path enables switching movements to be carried out in the immediate vicinity of the wall of the encapsulation housing.
- Such a curved path movement can be achieved, for example, by a link-like configuration of the contact piece.
- a curved path can also be achieved by pivoting a contact piece around a pivot axis.
- the shaft penetrates an outer wall of the housing in a cylindrical region of the housing.
- An arrangement of the shaft in the cylindrical region of the encapsulation housing allows the drive movement to be introduced relatively centrally into the encapsulation housing.
- the isolating switch or the earthing switch can then be arranged around this point of introduction.
- Figure 1 shows a first embodiment of a high-voltage outdoor bushing arrangement
- Figure 2 shows a second embodiment of a high-voltage outdoor bushing and the Figure 3 shows a third embodiment of a high-voltage outdoor bushing.
- the high-voltage outdoor bushing 1 has an electrically conductive housing 2.
- the electrically conductive housing 2 is made, for example, of aluminum or another metal.
- the electrically conductive housing 2 is preferably produced by means of a casting process.
- the housing 2 is arranged essentially rotationally symmetrically around an axis 3.
- the electrically conductive housing 2 has a first flange 4 and a second flange 5.
- the first and the second flange 4, 5 are also arranged coaxially to the axis 3.
- An insulating sleeve ⁇ is flanged to the first flange 4.
- the insulating sleeve ⁇ is designed in the form of an open-air bushing in a known manner.
- the electrically insulating sleeve 6 and the housing 2 surround a common gas space which is filled with an insulating gas.
- the insulating sleeve 6 is arranged coaxially to the axis 3.
- an electrical phase conductor is arranged coaxially to the axis 3.
- the electrical phase conductor has a first section 7 and a second section 8.
- the first section 7 of the phase conductor is surrounded by the insulating sleeve 6 and is guided to the outside at the free end of the insulating sleeve 6.
- the first section 7 of the phase conductor is through the first flange 4 passed into the interior of the electrically conductive housing 2.
- the second section of the phase conductor is guided through the second flange 5 into the interior of the electrically conductive housing 2.
- the second flange 5 is arranged at the end of a pipe socket 9.
- the pipe socket 9 is also arranged coaxially to the axis 3.
- the pipe socket 9 is surrounded by an annular current transformer 10.
- a separating section 11 is arranged in the interior of the electrically conductive housing 2.
- the isolating section 11 is formed from a stationary contact piece 12 and a movable contact piece 13.
- the stationary contact piece 12 is electrically conductively connected to the first section 7 of the phase conductor which projects through the first flange 4.
- the stationary contact piece 12 and the first section 7 of the phase conductor are insulated in the interior of the housing 2 via a columnar support insulator 14a.
- the second section 8 of the phase conductor which is guided through the second flange 5, is also secured in an insulated manner in the interior of the electrical housing 2 by means of a further columnar support insulator 14b.
- the movable contact piece 13 is designed in the form of a bolt.
- the bolt can be displaced along its longitudinal axis along a linear path lying obliquely to axis 3.
- a shaft 15 is passed through the wall of the electrically conductive housing 2 in a cylindrical region.
- the shaft 15 is designed as an electrically insulating shaft. The rotary movement of the shaft 15 is converted into a linear movement of the movable contact piece 13 via a rocker arranged on the shaft 15.
- the movable contact piece 13 has at its one end face a contact area which can be moved into the fixed contact piece 12 of the isolating section 11. At the end of the movable contact piece 13 facing away from the separating section 11, a contact area is arranged, which can be moved into a grounding contact 16 arranged inside the electrically conductive housing 2. If an opening movement of the movable contact piece 13 is continued, contact is made with the grounding contact 16. As a result, the second section 8 of the phase conductor can be grounded.
- the high-voltage outdoor bushing arrangement shown in FIG. 2 has a construction that is the same as that of FIG. 1 with regard to the electrically conductive housing 2 and insulating sleeve 6 and the flanges 4, 5. Only the contact system of the isolating section is modified compared to FIG. 1.
