Definitions
- the invention relates to a gas-insulated medium voltage switchgear with
- Busbar arrangement with a plurality of switching fields, in which T-connection elements form an electrical connection between the busbar and switch panel, according to the preamble of claim.
- Busbar arrangements for medium voltage installations are known which are designed for a current carrying capacity of 2,500 amperes and 1,250 amperes. These are e.g. around solid-insulated busbars.
- T-connectors are used.
- T-connection elements are known to correspond to the cable cross-sections of the busbar, both in the looping through section of busbar element to busbar element, as well as in the output section to the panel.
- the invention is therefore based on the object, a switchgear with
- the core of the invention is therefore that the T-connection elements are designed in the area of the outlet to the panel in the cable cross-section only on the current carrying capacity of the respective panel. Thus, only the looping through section in the T-connector on the required current carrying capacity of
- Busbar designed. In other words, only this section has the same cross-section as the busbars themselves. By contrast, the section going to the switching field is thus equipped, unlike in the prior art, only with the smaller line cross-section and thus the lower current carrying capacity. As an example, this means that the cross-section of the busbar is rated at 2,500 amperes of current carrying capacity, while the output to the panel is designed for 1,250 amperes.
- the T-connection elements are provided with a plastic insulation. This is important for the outside
- busbar and the T-connection elements are provided with a plastic insulation.
- the plastic insulation on the outer surface is provided with a carbonization layer.
- the carbonization layer is placed at ground potential.
- the busbar is designed in the conductor cross-section for a current carrying capacity of 2,500 amps and the T-connectors are designed in the cross section of the outgoing area for 1,250 amperes.
- a particular functional advantage is that when nennstromnton designed switchgear duch choice of the connector according to the invention a connection to a busbar with a higher rated current can be connected.
- FIG. 1 busbar arrangement in a schematic representation
- Figure 2 T-connection elements
- Figure 1 shows in the upper part of a solid-insulated busbar, which is designed for a total current carrying capacity of 1,250 amps.
- the outlets are also designed for the same cable cross-section, namely for 1,250 amperes.
- a busbar is designed for a current carrying capacity of 2,500 amperes. Only one of the panels is also on the same
- FIG. 2 shows in detail an inventive T-connector, in the middle part of the picture.
- the cross section in the outlet region down the same cross-section, as the through-connection of the busbar itself left shows the design to 2,500 amps and the right interpretation of 1,250 amps.
- the middle part of the picture shows the connecting piece according to the invention.
- This is provided in the interconnected busbar area with a larger, namely designed to 2,500 ampere cross-section, while the outgoing area is designed for a smaller cross section, namely for 1,250 amps. This then corresponds to the cross section for the current carrying capacity of the panel, and not the busbar.
