Definitions
- the invention relates to an encapsulated Voltage converter arrangement for switchgear with several plant fields that run alongside each other extending system axes are arranged, according to Preamble of claim 1.
- DE-U-9 209 167 is an encapsulated one Voltage converter arrangement known in the three in section round or elongated housing for one Voltage transformers are arranged side by side. If each voltage converter has its own housing while there are no particular problems with each other electrical insulation, but that's the arrangement also not designed multi-phase. On the other hand, that would be Building a multi-phase arrangement is no longer compact, if along the lines of this release a separate housing for each Voltage converter would be designed.
- JP-A-56 114308 is known to have three in a single housing To accommodate voltage transformers.
- the Core axes of the magnetic cores transverse to the longitudinal axis of an im Section rectangular case aligned and in Are arranged one behind the other in the longitudinal direction.
- the coils come very close so that the Dielectric strength can be impaired.
- the core axes again aligned parallel to each other, but the Voltage transformers are in a triangular formation housed in an average circular housing.
- DE-C-0 576 081 is a Voltage transformer arrangement with three in a row arranged voltage transformers known in the also the core axes of the magnetic cores transverse to Longitudinal axis of an elongated housing aligned and are arranged one behind the other in the longitudinal direction.
- the cores are by side, in Core legs extending in the longitudinal direction with one another connected. But here too is the distance between the Coils very low, so that the dielectric strength may be affected.
- the invention has for its object a encapsulated voltage transformer arrangement for switchgear to indicate with several plant fields, which a small Has housing width and still a sufficient Distance between the live components guaranteed, and to specify a switchgear these encapsulated voltage converter arrangements.
- the solution according to the invention is that the Voltage converters are also parallel to each other aligned but offset from each other.
- This arrangement uses both the case length and the case width are optimal without the coils arranged on the cores would be close to the housing walls.
- the The distances between the coils are large enough to To prevent voltage flashovers. This results in the advantage that switchgear with several Plant fields also several converter housings in one shorter distance can be arranged. This makes the switchgear more compact without Cut back on dielectric strength should be.
- this is Transducer housing elliptical in section, four Rectangularly arranged and rounded corners indicated are.
- This form of housing is particularly recommended if the interior of the converter housing with a Insulating gas, for example sulfur hexafluoride, under high pressure to be filled.
- the curved Housing walls only require a small wall thickness.
- the long sides are also flattened. This Housing shape is particularly advantageous if the Case length is not very much larger than that Case width.
- the task is the longitudinal axis of the housing Transducer housing substantially perpendicular to one level determined by the system axes and the voltage transformers are transverse with their core axes aligned to the longitudinal axis of the housing and in the longitudinal direction arranged one above the other, the cores being separated by two lateral, longitudinal core legs are integrally connected.
- the converter housing with its In this embodiment, the longitudinal axis of the housing is vertical, so that it can be recommended for switchgear, their installation space in width, i.e. across to the Plant axes is restricted, however, where vertical enough space is available upwards.
- the invention also relates to a Switchgear designed according to the invention Voltage converter arrangements.
- a Switchgear designed according to the invention Voltage converter arrangements.
- Such an arrangement is already due the inventive design of the Voltage converter arrangements more compact than known ones Switchgear.
- the converter housing 1 is essentially elliptical and has four rectangularly arranged and rounded corners 7. Two side walls 8 are curved and extend essentially in the direction of a Longitudinal axis 9.
- the voltage converters 2, 3, 4 are elongated Formation in the direction of the housing longitudinal axis 9 arranged one behind the other, the core axes 10, 11, 12 of the cores 5 parallel to the longitudinal axis 9 of the housing lie.
- the core axes 10 and 12 of a first and one third core 5 are laterally opposite to the left Longitudinal axis 9 shifted.
- a second middle one Core 5 with core axis 11 is on the right side shifted relative to the longitudinal axis 9 of the housing.
- the free ends 13, 14, 15, 16 of the cores 5 side by side and overlap lengthways.
- the Core axes 10, 11, 12 transverse to the longitudinal axis 9 of the housing aligned and the voltage converters 2, 3, 4 in turn arranged one behind the other in the longitudinal direction.
- the three Cores 5 are through two lateral, parallel to Longitudinal axis 9 of the core legs 17, 18 connected in one piece.
- Fig. 3 shows a converter housing 19, in which the Housing length l is not very much larger than that Housing width b is. Beyond that it is Transducer housing 19 flattened on its long sides, so that two straight, parallel side walls 20th arise.
- the three voltage converters 2, 3, 4 are star-shaped with radial core axes 10, 11, 12 arranged, the core axis 10 of a first Voltage converter 2 parallel to the longitudinal axis 9 of the housing is aligned and coincides with this.
- the two other core axes 11, 12 of the other two Voltage converters 3, 4 each point to the first Core axis 10 at an angle W of more than 120 °.
- the converter housing 21 shown in Fig. 4 is in essentially cylindrical, again the Housing length l larger than that of the cylinder diameter corresponding housing width b is. They are here too Voltage converters 2, 3, 4 with their core axes 10, 11, 12 arranged transversely to the longitudinal axis 9 of the housing, the Cores 5 through two lateral, parallel to Longitudinal axis 9 of the core legs 17, 18 are integrally connected.
- Embodiment of the invention are Longitudinal axis 9 of the transducer housing 21 perpendicular to a level determined by the system axes A, B, C aligned. In Fig. 7 this level corresponds to the Paper plane on which the housing longitudinal axes 9 are perpendicular stand.
- the cylindrical converter housing 21 then protrudes vertically upwards.
- the cylinder diameter of the Transducer housing 21 determines the housing width b, which in turn turns out to be advantageously small, since this one arrangement according to the invention within the circular Cross section accommodated only a voltage converter must be, since the three voltage converters 2, 3, 4 one above the other in the direction of the cylinder longitudinal axis are arranged.
- the three voltage transformers within the circular housing cross section side by side arranged in a star shape, resulting in a larger one Housing diameter and thus a larger one Housing width b results.
