OVERHEAD LINE CONNECTION TO A THREE PHASE GAS INSULATED METAL-CLAD HIGH VOLTAGE SWITCHGEAR

摘要

1. Overhead-line connection at a switching station comprising a three-pole encapsulated pressure-gas insulated high-voltage switching unit, wherein the overhead cables (19) are coupled to a supporting structure (20) by insulators (21) and then to feed-through ducts (8) on the three-pole encapsulated pressure gas insulated switching field (1), characterized in that the connection points (23) of the insulators (21) which couple the overhead cables (19) for a switching field (1) to the supporting structure (20) are staggered in depth and height in a plane which in particular is vertical and preferably lies on the centre axis in the region of the field division of the switching field (1), and that the feed-through ducts (8) of the switching field are arranged in series in this plane.
